Specifically, the distribution valve controls the distribution and transmission of air pressure signals by adjusting the valve position in the air circuit to achieve the switching and movement of pneumatic equipment. In transportation equipment, the brake distribution valve is a control device in the brake system that can distribute the hydraulic pressure generated by the master cylinder to the brakes of each wheel, thereby achieving independent braking of each wheel.

[0029] Embodiment 1

[0031] The regulating mechanism 2 includes an adjusting component 21 and a locking component 22, and the locking component 22 is arranged on the surface of the adjusting component 21;

[0032] The buffer mechanism 3 includes a mounting base 31, and there are four mounting bases 31. The four mounting bases 31 are respectively fixedly connected to the four ends of the top of the valve body base 1.

The top of the exhaust leakage cylinder 35 is fixedly connected to a support bent strip 37, and the left surface of the support bent strip 37 is slidably connected to a T-shaped round support strip 38. The bottom end of the buffer cylinder 32 is opened There is an exhaust smooth cavity 39, and circular through holes are provided in the middle of the mounting base 31 and in the middle of the limiting circular plate 34. The top of the buffer cylinder 32 is fixedly connected to the support cylinder 36, and the adjustment component 21 includes a support seat 211, and the support seat 211 is fixedly connected to the side of the buffer cylinder 32. The bottom end of the support seat 211 is fixedly connected to a first spring 212, and the top of the first spring 212 is fixedly connected to a limiting slide plate 213. The left and right ends of the limiting slide plate 213 are respectively fixedly connected to damping movable bars 214, and a damping support bar 215 is arranged inside one end of the damping movable bar 214.

[0033] Furthermore, a limiting groove is provided inside the support seat 211, and the surface of the limiting slide plate 213 is slidably connected to the inside of the limiting groove. Deep grooves are provided inside one end of the damping movable bar 214 and on the corresponding side of the damping support bar 215. The deep grooves provided inside the damping movable bar 214 are tightly fitted with the deep grooves provided inside the damping support bar 215. When high-pressure gas is exhausted, the tight fitting connection between the deep grooves inside the damping movable bar 214 and the deep grooves inside the damping movable bar 214 is utilized, so that a certain damping effect can be exerted on the limiting circular plate 34 when impacted by the gas in the valve, and the damping movable bar 214 is moved left and right and the contact area between the deep grooves between the damping movable bar 214 and the damping support bar 215 is changed, so as to achieve the effect of changing the adjustment of the exhaust damping effect.

[0034] Embodiment 2

[0035] See also Figure 1-6 On the basis of the first embodiment, the positioning component 22 further comprises a T-shaped block 221, which is slidably connected to the inside of the damping movable bar 214, a shift block 222 is fixedly connected to the left side of the T-shaped block 221, and the upper and lower ends of the right side of the shift block 222 are respectively fixedly connected to the second spring 223, the right end of the second spring 223 is fixedly connected to the I-shaped bar 224, and the upper and lower ends of the right side of the I-shaped bar 224 are respectively fixedly connected to the positioning bar 225, a hollow positioning long plate 226 is fixedly connected to the surface of the damping movable bar 214, a positioning hole is provided inside the hollow positioning long plate 226, and the surface of the positioning bar 225 matches the inside of the positioning hole, a cross groove is provided inside the damping movable bar 214, and openings are provided at both the front and rear ends of the cross groove, and the middle of the surface of the T-shaped block 221 is slidably connected to the inside of the cross groove.

[0036] Furthermore, a smooth groove is opened in the middle of the buffer cylinder 32, the surface of the limiting circular plate 34 is slidably connected to the inside of the smooth groove, an exhaust hole is opened at the top of the buffer cylinder 32, openings are opened at the upper and lower ends of the support cylinder 36, the bottom end of the support cylinder 36 is connected to the top of the buffer cylinder 32, and the surface of the exhaust funnel 35 is slidably connected to the inside of the support cylinder 36. Part of the gas quickly enters through the circular through hole in the middle of the limiting circular plate 34 and impacts the exhaust funnel 35 to drive it to move upward, thereby driving the exhaust funnel 35 to move upward under the support of the inner wall of the support cylinder 36, thereby exposing more leakage holes on the surface of the exhaust funnel 35 outside the buffer cylinder 32, and discharging the high-pressure gas, thereby performing a certain gas buffering effect.

[0037] In actual operation, when the device is used, high-pressure gas is transported upward from the inside of the valve body base 1, wherein the gas passes through the exhaust smooth cavity 39 and impacts upward, and part of the gas quickly passes through the round through hole in the middle of the limiting circular plate 34 and impacts the exhaust leak cylinder 35 to drive it to move upward, thereby driving the exhaust leak cylinder 35 to move upward under the support of the inner wall of the supporting cylinder 36, thereby exposing more of the leakage holes on the surface of the exhaust leak cylinder 35 outside the buffer cylinder 32, thereby discharging the high-pressure gas, thereby performing a certain gas buffering effect, and then performing a protective effect on the inside of the equipment, and utilizing the close fitting connection between the deep tooth grooves inside the damping movable bar 214 and the deep tooth grooves inside the damping movable bar 214, thereby being able to play a certain damping effect on the limiting circular plate 34 when it is impacted by the gas in the valve;

[0038] Later, during the exhaust process, the limiting circular plate 34 and the exhaust funnel 35 may quickly impact the inside of the buffer cylinder 32, causing excessive damage to the inside of the buffer cylinder 32. Therefore, in order to reduce the damage to the inside of the equipment caused by this impact, the exhaust funnel 35 drives the supporting bent bar 37 to drive the limiting slide plate 213 and the damping movable bar 214 to move upward when moving upward. At this time, the I-shaped bar 224 is moved away from the hollow positioning long plate 226, thereby driving the positioning bar 225 to detach from the hollow positioning long plate 226, and then the damping movable bar 214 is moved left and right and the contact area between the deep tooth grooves between the damping movable bar 214 and the damping support bar 215 is changed, so as to achieve the adjustment effect of changing the exhaust damping effect, and after the adjustment is completed, the positioning bar 225 is reinserted into the hollow positioning long plate 226.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
