The prior art describes a safety valve that includes a valve body assembly and its device. rigid attachment to the product, where for scheduled replacement of a valve or safety valve that has come out out of order in the field, and compliance with the rules and safe operation of devices operating under pressure, as well as 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 with vertical holes (patent UA 45227, published on 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 utility model, there is an expansion of functionality and simplification of the design valve, by its reconstruction (patent UA 61728, published 25.07.2011) A valve is known from the prior art, 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 shutter and valve shutter (patent UA 37396, publ. 11 / 25 / 2008) The prior art describes a valve comprising a housing 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 made of two parts, mounted on a rod hingedly using an axis with the possibility of rotation in longitudinal vertical plane. The known solution relates to pneumatic-hydraulic systems, namely - for valves with a closing element (patent UA 40207, published on 25.03.2009). The prior art describes a valve comprising a housing with valves placed therein - overpressure and vacuum, loaded with compression springs, adjustable 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 the movement of the excess pressure valve under the action of excess pressure in the container on which the safety valve is installed. The task of a known useful model is to increase the efficiency of the safety valve by simultaneously functioning of valves - excess pressure and vacuum - when triggered by an increase gas pressure in the tank exceeds that established by the design documentation (patent UA 104230, publ. 01 / 25 / 2016). The prior art describes a valve in the body of which there is a closing member, which includes concentrically arranged movable bushings, between which a sealing element is located, and which individually connected to the springs pressing them against the saddle, where the inner sleeve spring placed in the through-groove of the housing under the saddle, connected to its sleeve through a rod placed coaxially to the locking member, and is made with a stiffness that exceeds the stiffness of the outer spring bushings. The known technical solution is based on the task of improving the safety valve, by making changes to the design of the shut-off element and a corresponding change in its location elements in the housing, to ensure a reduction in the device's operating differential (patent UA 50012, publ. 05 / 15 / 2001). The closest analogue of the utility model has not been found. The basis of the claimed technical solution is the task of creating such a regulating valve, which provides a connection between the vehicle tire locking system and the pressure regulation system in tires with a pneumatic vehicle system. The regulating valve is installed after the vehicle's receiver. The control valve ensures the functioning of the tire locking system and the control system. tire pressure, provided that the receiver has a pressure higher than the required, pre-set pressure value. If the pressure in the receiver is lower than required - the tire locking system and the tire pressure regulation does not function, and the receiver provides only the vital functions vehicle functions. The task is solved by means of a regulating valve according to the utility model, which consists of a housing, an adjusting nut, inlet and outlet fittings and mounting brackets, at the same time, a spring-loaded spool with a single-acting cuff is installed in the middle of the housing, where the adjustable nut is designed to allow the valve to be pre-set to a certain value pressure, and the spring-loaded spool with a single-acting cuff is made with the possibility of movement, opening the air channel.

A detailed description of the preferred embodiment of the technical solution will be provided below. A specialist in Based on this detailed description, further development and refinement of the useful models. The utility model - the valve - consists of a body, an adjusting nut, an inlet and an outlet fittings and mounting brackets. A spring-loaded spool is installed inside the housing with single-acting cuff. The adjusting nut is made with the possibility of preliminary valve setting to a certain pressure value. Spring-loaded spool with one-way cuff The action is performed with the possibility of movement, opening the channel for air. The utility model works like this. The regulating valve is installed after the vehicle's receiver. Regulating valve ensures the functioning of the tire pressure regulation system and tire locking system only when conditions of the presence of pressure in the receiver greater than the required, preset value. If pressure in the receiver is lower than required - tire pressure regulation system and locking system the tires do not function, while the receiver provides only vital functions vehicle. The control valve ensures the passage of compressed air through it only if its pressure value is equal to or greater than the required value preset on the valve. If the compressed air pressure supplied to the valve is lower than required, the valve does not open and does not allows air to pass through. Before starting work, using the adjusting nut, the valve is pre-adjusted to a certain pressure value. Compressed air, from a pressure source, is supplied to the inlet fitting. If the supplied pressure value is equal to or greater than the preset value on the valve, compressed air passes through the valve and exits through the outlet fitting. If the pressure value that supplied is less than the preset value on the valve, the valve closes and does not passes compressed air through it. It should be understood that the above-described examples and embodiments are illustrative only and Various modifications and changes are suggested to those skilled in the art, which are within the scope of this application. and the scope of the utility model formula. It should be understood that the above information does not in any way limit the scope of rights under the application.
