A well-known analogue is the safety valve of a vehicle's pneumatic brake system, which contains a hollow body with inlet and outlet openings and with covers fixed therein, made with stops, the piston, placed in the cavity of the housing, is spring-loaded relative to the covers and made with central radial and axial holes, spring-loaded locking elements, saddles locking elements made on the ends of the said piston coaxially with the hole therein, while for increasing the efficiency of compressed air distribution by increasing the sensitivity of the valve, it provided with a spool placed in the said coaxial bore of the piston with the possibility of movement, while the spool is made with a dividing disk in the middle part and axial grooves on the surface that form channels for air passage in the piston hole, and the locking elements spring-loaded relative to the spool and placed at its ends with the possibility of interaction with the cover stops (patent SU 797931, published on January 23, 1981) A well-known analogue is an electropneumatic valve for railway brakes, which contains a housing, control and power supply system unit, valve, power coil, contacts, sealing ring, spring, stop, the valve is installed in the mounting tees, which are connected through end valves and brake hoses with rubber sealing rings to the previous or subsequent elements of the train's rolling stock, in this case, the valve device is equipped with toroidal coils placed in rubber sealing rings of brake hoses. The basis of the known analogue is the task improvement of the electropneumatic valve of railway brakes by providing The rubber sealing rings of the brake hoses contain toroidal coils connected by wires to an electropneumatic valve for railway brakes, through which power is supplied and control of the valve itself according to the transformer principle, which prevents the harmful effects of dust, dirt, sand and grease on the effective operation of braking systems in operating conditions. Electropneumatic valve with a section of brake line with structurally significant elements contains a toroidal coil placed in a rubber sealing ring, a brake sleeve, end valve, mounting tee, valve itself, section of brake line pipe, which connects the specified node to other brake elements (main reservoir, air distributor, etc.) (patent UA 7893, published on 15.07.2005). An analogue is a safety valve, which contains a valve body assembly and a device for its rigid attachment to the product, where for scheduled replacement of a valve or safety valve that has failed in field conditions, and compliance with the rules and safe operation of pressure devices, and also general explosion safety rules for explosive, chemical, petrochemical and oil refining industries, the valve in the lower part is equipped with a diaphragm safety a device made in the form of a cylindrical body with upper and lower annular grooves on horizontal planes of the body, connected by a continuous vertical opening with a horizontal the opening of the pipeline - the fitting connected to the compressor, and the second solid opening, which passes through the wall of the membrane safety device housing, made horizontal in the safety device housing and connects the internal cavity of the safety device with the second pipeline - a fitting designed to connect a pressure gauge, and the diaphragm housing The safety device is equipped with horizontally arranged gaskets at the top and bottom with vertical holes (patent UA 45227, published 26.10.2009) Known valve comprising a housing with an axial channel, a connecting fitting, a metering a working element rigidly connected to the pusher, as well as a drive for the working element, where the working the element is made in the form of a ball, and the pusher is in the form of an expansion tube covered by a casing, while the drive of the working element and pusher is made in the form of a resistive heater, connected to a source of electrical control signal. The problem to be solved is known analogue, is an expansion of functionality and simplification of the valve design, by its reconstruction (patent UA 61728, published 25.07.2011) An analogue is the well-known valve, which consists of a cylindrical sleeve with a seat, spring-loaded valve, flange and sealing elements forming three hydraulic cavities located along fluid flow "before the gate", "after the gate", "after the seat" - between the cavities "before the gate" and "after "gate", while the gate has a throttle hole that connects the cavity "behind the gate" with cavity "in front of the shutter", in the cavity "behind the shutter" an additional shutter is made, which has the possibility of blocking the throttle hole in the bolt, with the spring located between the additional gate and valve gate (patent UA 37396, published 25.11.2008) An analogue is a valve containing a body with a stem that acts on a rupture element located coaxially with the inlet and outlet fittings, and a pyro cartridge, where the bursting element is made of two parts mounted on a rod hingedly by means of an axis with the possibility of rotation in the longitudinal direction vertical plane. The analogue belongs to pneumatic-hydraulic systems, namely to valves with locking element (patent UA 40207, published 25.03.2009). An analogue is a valve containing a housing with valves placed in it - excess pressure and vacuum, loaded with compression springs, regulated by separate devices, and The vacuum valve is placed inside the excess pressure valve, where the movement of the vacuum valve is limited in the direction of movement of the overpressure valve under the action of the overpressure in container on which the safety valve is installed. The task of the known analogue is to increase the efficiency of the safety valve operation by the simultaneous operation of the valves - overpressure and vacuum - when triggered by an increase in gas pressure in the tank above established by the design documentation (patent UA 104230, published on 25.01.2016). An analogue is a valve, in the body of which there is a closing element containing concentrically movable sleeves are located, between which a sealing element is located, and which are individually connected to the springs pressing them against the saddle, where the spring of the inner sleeve is placed in the passage in the housing groove under the saddle, connected to its sleeve through a rod placed coaxially with the shut-off body, and is made with a stiffness that exceeds the stiffness of the spring of the outer sleeve. The basis analogue, the task is set by improving the safety valve, making changes to the design of the shut-off element and the corresponding change in the location of its elements in the body, to ensure a reduction in the device's operating differential (patent UA 50012, published 15.05.2001 r.). The closest analogue to the utility model has not been found. The utility model is based on the task of creating a blocking valve that provides quickly releasing pressure from the vehicle's wheel, as well as ensuring that the wheel is locked in emergency situations (breakage of the pressure supply tube to the wheel). The problem is solved by the fact that, according to the utility model, the blocking valve contains housing, disc washer, bracket, fittings, while inside the housing is installed spring-loaded diaphragm, spool and one-way seal, where the disc washer is made of with the possibility of pressure relief, and the bracket is designed to allow the valve to be fixed to the wheel vehicle, where the fittings are designed to allow the connection of a valve. The fittings are designed to allow the valve to be connected to a stationary air source. The fittings are designed to allow the valve to be connected to the wheel. The fittings are designed to allow the valve to be connected, if necessary, to an external source. compressed air. Given that a utility model can be modified and have alternative options embodiment, the following description is given as an example to characterize the essence of the utility model and the possibility of its material realization. It should be obvious that the detailed description provided is not intended to limit the utility model to the given individual embodiments, but vice versa, includes all modifications, equivalents and alternatives that fall within the spirit and scope of the patent protection defined by the utility model formula. The utility model is explained by drawings. Fig. 1 conventionally shows a general view of the blocking valve. Fig. 2 schematically shows a blocking valve, top view. Fig. 3 schematically shows a blocking valve, side view. The above figures are given as an example to characterize the essence and possibility of implementation, of the object described in the formula. The following is a detailed description of a preferred embodiment of the utility model. The blocking valve consists of a housing, inside which is placed a special spring-loaded diaphragm, spool and one-way seal, and on which a disc washer is placed for discharge pressure; from a bracket designed to secure the valve to the vehicle wheel, and fittings. Using fittings, the valve is connected to a stationary air source, a wheel and, finally, if necessary, to an external source of compressed air. The utility model works as follows. Air, from a stationary source with a certain, necessary pressure, is fed into a valve, which passes it into the inner cavity of the wheel, inflating the wheel to given pressure. If the pressure supplied from a stationary source of compressed air is greater than the pressure in wheel, the valve passes it through a one-way cuff into the inner cavity of the wheel until the pressure value in the wheel will not be equal to the pressure supplied from the source. If the pressure supplied supplied from a stationary source of compressed air less than the pressure in the wheel, the valve, for using a cuff, blocks the pressure supply from the source to the wheel and opens, using spool and membrane, releasing excess pressure from the wheel, pressure is released from under the disc washers on the valve body until the pressure value in the wheel is equal to the pressure supplied from the source (due to the large cross-section of the exhaust opening, fast pressure relief). If it is necessary to inflate the wheel from an external source of compressed air, use a special fitting with a built-in nipple, which is fixed to the bottom valve. This fitting allows you to quickly and conveniently connect an external source of compressed air and pump the wheel to the required pressure. In the event of an emergency, such as a puncture compressed air supply tubes from a stationary compressed air source, the valve instantly covers the wheel, using a spring-loaded membrane inside the valve, and the pressure in the wheel remains unchanged (the wheel does not go down). The blocking valve is installed directly on the vehicle wheel, which allows inflate tires from an external source of compressed air (such as a stationary - installed directly on the vehicle, and from an external one - connected through a special fitting with nipple). The blocking valve provides quick pressure relief, as well as locking the wheel in emergency situations (breakage of the pressure supply tube to the wheel). It should be understood that the above-described examples and embodiments are illustrative only and specialists in this field are offered various modifications and changes that cover the essence of usefulness model and the scope of the utility model formula.
