Briefly about the purpose of the KDM mechanical valve

The main task of the KDM is to save petroleum products and significantly reduce the loss of petroleum products due to poor sealing of the working tank space. Thus, KDM 50 valves are products that are similar in all operating conditions to KDS-3 valves. Frost resistance and high strength of the metal are two main and major advantages.

Installation is simple, low weight is an additional advantage of the product over its competitors. Also, KDM products have a reduced risk of primary and secondary damage during extreme or normal transportation. Use and installation have also become easy: there is now a redundant suspension clamp.

The valve has a built-in fire protection that can prevent fire from entering the tank. The presence of fasteners in accordance with OST 26-2043-91 helps to operate products in various industries - petrochemical and chemical.

In the future, KDM valves need to be replaced with KDS-3 valves, which have high quality characteristics.

How the mechanical breathing valve KDM 50 is used in the enterprise

Its use is strictly regulated by the main OST and PB - “Industrial Rules”. Safety of oil depots and petroleum product warehouses" (according to PB 03-560-03) and "industry standards" (according to OST 26-2043-91).

The KDM valve has the following designs

U, UHL, TS, TV with cat. placement 1 according to GOST 15150-69. — resistance to various influences of climatic factors.

Connecting sizes - KDM - 250, 1150, 50M, 50, etc. Breathing valves manufactured by SZNRO TU 3689-001-56510196-2009 in compliance with TU 26-02-1111-94.

Domestic new road cars

This review will focus on machines developed and put into mass production in 2013. Today this technique is the embodiment of the most advanced developments in the field of CDM production.

And so, let's start with Russian devices. Perhaps one of the most affordable road combination models now can be called SAAZ MDK-432932 , produced by the Skopinsky Automotive Unit Plant. For 1.9 million rubles, the customer receives a machine designed for all-season maintenance of hard road surfaces.

Using the electronic remote control in the driver's cabin and the hydraulic drive of the equipment, you can control: – a salt-sand spreading unit with a salt moistening system, a system for width distribution and maintaining a constant density of reagents; – high-pressure watering equipment with rotating nozzles and a comb with nozzles; – four types of dumps (included) and two types of brushes (included), plus – additional equipment for collecting water from reservoirs.

More expensive, but also more functional equipment of this type is produced today by the Arzamas Municipal Engineering Plant. KO-829B1 machine is currently the leader in sales among Russian-made KDM.

For 3.1 million rubles, the customer receives a 280-horsepower diesel vehicle on a KAMAZ base chassis. The machine includes: a 12 cubic meter tank. m. and watering equipment with a throw range of 20 m; deicing material distributor body for 8 cubic meters. m, as well as a brush and blade with a working area width of 2.5 m.

ED-405 will cost a little more . M.I. Kalinina. The device on the KAMAZ 65115-62 chassis, worth 3.3 million rubles, is equipped with: a 13.5 cubic meter tank. m. (water ejection range from 4 to 18 m) and a sand spreader body similar to the Arzamas one for 8 cubic meters. m. (distribution of PGM from 2 to 10 m). The kit also includes a brush and a blade with a working area width of 2.5 to 3 m.

Breathing valve

To ensure explosion-proof operation at RVS, specialized equipment is required. Breathing valves are considered such equipment and are considered an integral part of vertical tanks. The formation of vapors and the origin of evaporation is considered a normal phenomenon during the storage of petroleum products, as well as during loading and unloading operations. If the ambient temperature changes, the pressure may also change during the day. Such processes can be characterized as “breathing” and can lead to an increase in pressure in the gas space, which can lead to explosion and destruction. To avoid such incidents, it is advisable to install safety and breathing valves.

What is KDM?

The Region 45 road equipment plant sells reliable road equipment of the highest quality. Combined road vehicles are in great demand.

Features of combined road vehicles

Various municipal services require specific devices and vehicles for use in cleaning roads and areas adjacent to them. Among them are equipment for watering, snow removal, and sand spreading, which are mounted on trucks. Moreover, each specific type of special equipment is used in a certain season. Thanks to road-combined machines, it is possible to use the load-bearing chassis all year round by installing the necessary attachments on it, taking into account the time of year and the needs of utility workers.

Combined road vehicles, regardless of the type of chassis on which the equipment is installed, have a single design. For all types of such special equipment, certain types of mounted modular devices are provided.

In this case, water is transported in tanks, filled through a hatch on top or using a built-in pump. To regulate the location of the spray nozzles, a special hydraulic drive is used. As an option, you can sometimes connect a hose with a lock gun to wash individual items, such as road markers or signs. At the same time, this technique has special rotating brushes with rather rough bristles. At the same time, rotation is also provided by a hydraulic drive with a frequency of 300-600 rpm, taking into account specific purposes (the frequency is set by the driver-operator).

The functioning of the hydraulic units is ensured by an oil pump. The use of such equipment in winter implies the need to retrofit the chassis with all the required devices. Typically, the use of simple and high-speed snow dumps, a special body, a trapezoidal section, and equipment for spreading sand or other reagents (for example, salt) is required.

The sand spreading equipment has a drive that drives the power take-off. In this case, the chains are located outside the receiving body and have corrosion protection. To spray liquid reagents, such special equipment is equipped with nozzles, and the container itself for the sprayed substances is made of polyethylene, which can withstand various temperature fluctuations.

Snow plows can be of different types. In particular, the front one has a special rubber blade that can replicate all the unevenness on the road, and the angle with the height of the blade is regulated by a hydraulic cylinder. In addition, you can install a side blade, which is protected from collision with any obstacle. If necessary, use a middle blade installed in place of the brush. This device is equipped with a steel blade and is used to remove rolled and dense layers of snow. In addition, you can always adjust the working width.

Types of KDM

Combined road special equipment is divided into several categories based on the type of chassis used:

A – with wheel formula 6*4 and 6*6;
B – with the wheel formula 4*2.

At the same time, the chassis of the 1st group assumes its use on MAZ, KamAZ vehicles or imported similar vehicles for removing snow on highways and wide streets, when there is no need for special maneuverability, but speed and efficiency of work are of great importance.

Chassis of the second category are used on ZILs and their analogues, capable of performing work in simple urban conditions, including rather narrow passages, traffic jams and limited space for turning special equipment.

Depending on the type of change of KDM attachments, you can also buy several types:

vehicles with a standard layout;
special equipment with a multi-lift system.

In the first case, schemes are used when it is possible to replace certain types of devices on the chassis. In other words, a specific device (tank, bunker, etc.) is installed separately on the chassis manually or using a crane. At the same time, category A products provide special jacks with stands to facilitate installation.

In the second case, it is proposed to use vehicles in the form of a dump truck, on the body of which the necessary device is installed, including equipment that supplies the sand mixture, which is attached to special brackets. This option is the most profitable, since the car can also be used as a simple dump truck.

The version of special equipment with a multi-lift contains a device that tightens the necessary equipment onto the chassis using a winch with cables. It is then secured to the frame in the traditional way. Sometimes such road special equipment is equipped with special electronic systems to monitor the density and volume of sand mass or reagents to prevent possible troubles associated with ice.

The scope of use of combined machines for roads implies that they will be used for watering work on asphalt or concrete, in roadside areas, squares, parks, for cleaning roads with a brush, for clearing roads of snow; for the distribution of special mixtures and compounds on roads and much more.
