Description

A kind of pressure reducing valve with pressure stabilizing noise abatement

Technical field

The utility model relates to valve body technical fields, and in particular to a kind of pressure reducing valve with pressure stabilizing noise abatement.

Background technique

In the application process of valve body, pressure reducing valve will use mostly, and in the technical process for casting of pressure reducing valve, usually Fixed restriction device can be added, people can usually be referred to as throttle valve, during traditional pressure reducing valve use, mostly use greatly Spool and threaded stem assembly connection, often will appear valve body being not enough due to unlatching during unlatching in this way, from And the cause water inlet and the unlatching of the water outlet of water outlet junction of indirect are not enough, so as to cause water flow after outflow Pressure expected pressure is not achieved, i.e. decompression is not enough, and often along with big in the use process of pressure reducing valve The noise of amount has seriously affected the mood of operator.

Utility model content

In order to solve the above technical problems, the utility model is designed to provide a kind of pressure reducing valve with pressure stabilizing noise abatement, Achieve the purpose that noise is stablized and reduced in decompression.

To achieve the above object, a kind of pressure reducing valve with pressure stabilizing noise abatement of the utility model, including valve body, throttle orifice Plate, spool, noise-decreasing device, sleeve, reset spring, sliding block, sliding bar, fixed link and handle, the restricting orifice are arranged in institute The junction of the inlet and outlet of valve body is stated, the sleeve is fixed at the top of the restricting orifice, the spool Slidingtype is fixed in the sleeve, and the spool is equipped with boss, is offered on the sleeve lining and is matched with the boss The groove of connection is closed, the noise-decreasing device is fixed at the bottom of the spool, and the fixed link passes through the reset spring It is fixedly connected with the spool, the fixed link is fixedly connected with the sliding bar, and the sliding bar is by the sliding block in institute Displacement on sleeve lining is stated, the handle is fixedly connected with one end of the fixed link, is fixed with card on the handle It detains, is fixed with and the card slot snapped fit attachment on the valve body.

Further, the noise-decreasing device includes connecting rod, fixing seat, air bag, spring and sponge, is set on the restricting orifice There are several throttle orifices, the fixing seat is fixedly connected by the connecting rod with the spool, and the fixing seat passes through described Spring is fixedly connected with the sponge, and the air bag is fixed between the fixing seat and the sponge, in the air bag Equipped with lubricating oil.

Further, the throttle orifice is arranged at equal intervals on the restricting orifice.

It further, further include washer, the washer is fixed at the flow inlet of the valve body and the junction of outflow port, The washer is fixed at the lower part of the restricting orifice.

It further, further include strength of fluid sensor, controller and alarm, the strength of fluid sensor is arranged in institute It states in air bag, the strength of fluid sensor is electrical connected with the controller with the alarm.

Further, integrated at the inlet and outlet of the valve body to be fixedly connected with flange.

The utility model compared with prior art, the beneficial effect is that: setting handle plays operator is facilitated to turn valve Core is arranged after uniform throttle orifice can flow through restricting orifice in order to water flow, the stream of water flow to open valve body and valve body Speed and pressure are equal, and when flowing through restricting orifice due to water flow, can generate cavitation noise, thus profit can be smeared in throttle orifice Lubricating oil so that water flow and throttling hole wall generate friction and loss of energy can reduce noise, when valve body when closed, due to spool Decline, and then fixing seat extruding gasbag can be made, the lubricating oil in air bag is extruded and penetrates into sponge, is again turned on Valve body, air bag revert to original state under the elastic reaction of spring, and convenient to use next time, sponge moves upwards in turn, and right Restricting orifice is smeared, it is possible thereby to reduce cavitation noise, sponge is continued up, and can also be applied to sleeve lining It smears, prevents from getting rusty, influence to open, setting washer can be played when valve body is closed, and leveled up spool, prevented the leakage of water；

Sliding block is set between sliding bar and sleeve lining, sliding bar can be made only to do directed movement in the vertical direction, Cooperated between spool and sleeve using boss and groove, spool can be made only to do directed movement in the vertical direction, it is above-mentioned Synergy compress reset spring can only in the vertical direction or diastole, extend the service life of reset spring, when When valve body is closed, i.e., buckle fastening card slot, reset spring play the role of buffering, when valve body is opened, due to the pressure of water inlet Power is fixed value, thus position when spool can be made to be restored to unlatching, ensure that water outlet is completely opened, guarantees decompression Stablize.
