Automatic adjuster

Abstract

The invention discloses an automatic adjuster. The automatic adjuster comprises a valve body and a valve element; the valve element is arranged in the valve body and can move in the axial direction of the valve body, one end of the valve body is provided with an inlet, and the valve wall is provided with an outlet; the valve element comprises a pressure-adjustment spring, an adjustment valve element body, a reset spring and a valve element block; the pressure adjustment spring is arranged in the axial direction of the valve body and is connected to the adjustment valve element body in a sleeved manner, and one end of the pressure adjustment spring is movably connected with the bottom of the valve body in the initial state; the top of the adjustment valve element body is provided with an opening communicating with a valve body opening and stretches inwards from the opening to the bottom of the adjustment valve element body to from a cavity, and the bottom of the cavity is provided with a through hole; and one end of the reset spring is connected with one end of the valve element block, the valve element block is embedded into the cavity of the adjustment valve element body, the other end of the reset spring is fixed to the top of the adjustment valve element body, and the top edge of the adjustment valve element body is furthermore provided with an annular adjustment chuck. By means of the automatic adjuster, two-way ventilation can be achieved, the work pressure is adjustable, self-locking can also be achieved, and error operation is avoided.

Description

technical field [0001] The present invention relates to a valve, in particular to an automatic regulator. Background technique [0002] The brake valve is a part of the automobile air brake braking system. An automatic switch valve is often used in the brake valve. In an automatic switch brake valve with adjustable working pressure and its realization method, the function of the automatic regulator is to communicate with the The air port and air outlet, but in the air return process of the brake valve, it is necessary to add an additional one-way valve to realize the air return process. After the additional one-way valve is added, the disadvantages of the brake valve are very prominent: 1 1. Additional one-way valves increase costs; 2. Some air passages need to be set separately, and one-way valves are installed in the air passages, which makes the structure of the entire brake valve complicated and is not conducive to processing and production; 3. Too many and chaotic Open...

[0002] The brake valve belongs to a part of the automobile air brake braking system. An automatic switch valve is often used in the brake valve. In a working pressure adjustable automatic switch brake valve and its realization method, the function of the automatic regulator is to connect the Air port and air outlet, but in the air return process of the brake valve, it is necessary to add an additional one-way valve to realize the air return process. After the additional one-way valve is added, the disadvantages of the brake valve are very prominent: 1 1. Additional one-way valves increase costs; 2. Some air passages need to be set separately, and one-way valves are installed in the air passages, which makes the structure of the entire brake valve complicated and is not conducive to processing and production; 3. Too many and chaotic airways can make the flow of gas more difficult to control
