Abstract
The utility model provides a pressure reducing stabilizing valve which is composed of the component parts of a valve body, a spring, a spring shield, a stopper plug, a valve core, a piston bush, a valve seat, a limiting nut, an O-shaped sealing ring, etc., wherein a groove diaphragm is arranged on the upper end of the valve core, a hole is arranged in the center of the valve core, and the hole is connected with a cavity between the diaphragm and the piston bush. The utility model has the advantages that dynamic pressure is reduced, static pressure is reduced, and the pressure in the back of the valve has few changes which are 10 percents of the changes of the pressure in front of the valve. The utility model has large flow and stable operation. Low pressure water supply and constant pressure water supply can be realized.
Description
The utility model relates to a kind of valve.
Along with expanding economy, the tall building in city is more and more.Be to adapt to water system, various pressure loading valves produce in succession, though, can play the effect that reduces hydraulic pressure, defective is only to subtract dynamic pressure, do not subtract static pressure, can not satisfy the requirement of water system fully, especially can not adapt to the occasion that needs reduce pressure in some industrial production.
The purpose of this utility model is to propose a kind of decompression venting valve, and this valve not only subtracts dynamic pressure but also subtract static pressure at work, and has voltage stabilizing function.
The technical solution of the utility model is: decompression venting valve is made up of parts such as valve body, spring, spring shield, plug, spool, piston sleeve, valve seat, spacing mother and O RunddichtringOs, the spool upper end is provided with a fluted body diaphragm, center spool is offered a hole, and cavity communicates between this Kong Keyu diaphragm and the piston sleeve.
Before the described valve behind hydraulic action face and the valve ratio of the area of hydraulic action face be 1: 10.
Described fluted body diaphragm adopts rubber to add nylon net cloth and makes.
Valve of the present utility model is an open type spring diaphragm chip decompression venting valve, and its working principle is: downstream pressure is regulated by adjusting screw rod, and by the change open area of damming, the build-up of pressure loss realizes decompression.This valve is to go out under enterprising, when downstream pressure is delivered on the elastomer diaphragm by the center spool hole, makes flap and dam mouthful to keep a relevant position, closes and realizes subtracting static pressure when reaching the setting mouth that dams; When downstream pressure was lower than setting, the pressure of spring had been opened the mouth that dams again and has been carried out supercharging to pressing down spool, guarantees that downstream pressure is no more than setting.Since before the valve behind hydraulic action face and the valve hydraulic action face be 1: 10, the power that the power of 0.1mPa can the preceding 1mPa of equilibrium valve behind the valve is so there is pressure stabilization function.
The utility model has the advantages that: big flow, stable; Both subtract dynamic pressure, subtracted static pressure again; Downstream pressure changes little, only is 10% of upstream pressure variation; The requirement of no orientation is installed; Can realize low pressure, isobaric water supply, can economize on water, energy-conservation, simplify the equipment in the water system, reduce engineering cost.The removable parts part, the occasion of the voltage stabilizing that need in the industrial production also to can be applicable to reduce pressure.As: pressurized air, low-temperature steam, oils etc.
Below in conjunction with drawings and Examples, further specify the utility model.
Fig. 1 is a kind of embodiment's of decompression venting valve a sectional view;
Fig. 2 is the another kind of embodiment's of decompression venting valve a sectional view.
Fig. 1 illustrates the structure of the utility model decompression venting valve, with reference to Fig. 1, this valve comprises: plug lid 1, sealing gasket 2, stop nut 3, flap 4, seal ring 5, valve seat 6, interlock spool 7, O RunddichtringO 8, piston sleeve 9, valve body 10, fluted body diaphragm 11, nut 12, spring tray 13, spring 14, spring shield 15, adjusting screw rod 16, spring seat 17, acorn nut 18, screw 19, packing ring 20, sealing gasket 21,22 and packing ring 23; Its design key part is a band groove 111 is fixed in interlock spool 7 upper ends below spring tray 13 a elastomer diaphragm 11, form cavity 24 between diaphragm 11 and the piston sleeve 9, the transverse holes 72 that interlock spool 7 centers are provided with a hole 71 and communicate with cavity 24, hole 71 communicates with hole 72, as shown in phantom in FIG..Valve body 10 left ends are water intake, and right-hand member is a water outlet, and water outlet pressure is set a setting by adjusting the position of adjusting screw rod 16.Change the open area of damming, the build-up of pressure loss realizes pressure-reducing function.When water outlet pressure reached setting, downstream pressure was delivered to cavity 24 by spool 7 center holes 71,72, promoted diaphragm 11, drove on the spool 7 and moved, and closed the mouth that dams, and realized subtracting static pressure.When current entered valve body 10, if water outlet pressure is during less than setting, downstream pressure was delivered to cavity 24 by the hole on the spool 7 71,72, making spring 14 compression diaphragms 11 drive spool 7 moves down, make mouthful increase of damming, so the increase of water outlet pressure, thereby play pressure stabilization function.
Since before the valve behind hydraulic action face and the valve ratio of the area of hydraulic action face be 1: 10, downstream pressure can the preceding 10 multiplication of voltage power of equilibrium valve.
But the utility model both level is installed, and also can vertically install.
Referring to Fig. 2, when whole valve body was big, the plug lid replaced with bottom flange, and is connected with valve body with screw, and the pressure feedback mechanism of its spool is identical, does not describe in detail here.
