AI Technical Summary
After long-term use of the existing pressure regulator valve, the piston sliding range becomes smaller due to the accumulation of dirt in the slide chute, resulting in an imbalance in the pressure reduction ratio and the dirt cannot be effectively cleaned.
A light-duty fire-fighting pressure stabilization valve is designed, using a movable valve spool and pushing ring. The sliding ring drives the push ring and metal ball vibration, changes the water flow pressure, cleans up the dirt in the valve body, and combines the filter net and elastic plate to ensure the sliding ring. and smooth movement of metal balls.
The problem of dirt accumulation is effectively solved through the vibration cleaning mechanism, maintaining the pressure reduction ratio of the valve, and extending the service life.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of valves, in particular to a light fire-fighting pressure-stabilizing valve. Background Art
[0002] A pressure-stabilizing valve generally refers to a pressure-reducing valve, of which there is a proportional pressure-stabilizing valve. When there is no water in the pipe network behind the valve, the valve is closed, and the pressure ratio before and after the valve is a constant value. When the fire hydrant or sprinkler is used to spray water in the pipe network behind the valve, the pressure before the valve is greater than the pressure after the valve, pushing the piston backward to open the proportional pressure-reducing valve. The pressure in the pipe network behind the valve decreases with the increase of flow (in line with the flow-pressure characteristic curve) until it reaches a balanced position and the piston stops moving.
[0003] In the prior art, the piston slides through a slide groove provided on the inner wall of the valve body. However, after long-term use, dirt will be generated in the slide groove, which will reduce the sliding range of the piston and cause an imbalance in the pressure reduction ratio in the pressure regulating valve.

[0029] By sliding the sliding ring 64, the push ring 62 can be driven to move, which can drive the metal ball 61 to move, which will cause the inner wall of the valve body 1 to vibrate, and then the water pressure in the lower pipeline is changed by switching the main valve of the water flow, so that the valve core 4 moves to allow the dirt to be better cleaned through the effect of vibration. In addition, the push ring 62 is set in its middle position to allow the metal ball 61 to be evenly distributed on both sides, and a gap is left at the bottom of the push ring 62 but the metal ball will not be stuck in it, in order to ensure that it can slide well.
