Abstract
The invention relates to a one-way pressure-control tap water valve which comprises a valve body with internal threads arranged at the two ends and a valve cavity formed in the valve body. One end of the valve cavity is fixed to a protruding shoulder in the valve body and the other end of the valve cavity is in interference fit with the inner wall of the valve body. A valve element located through a shaft shoulder at one end of the valve cavity, a reset spring and a valve deck fixed to the other end of the valve cavity are sequentially arranged in the valve cavity. The valve element is provided with a damping hole. The position, overlapped with the valve element, on the valve cavity is provided with a drainage hole. A pilot valve port is formed between the valve element and the valve deck. A handle is arranged on the valve body, wherein one end of the handle extends into the valve body and is connected through a thread. The end, extending into the valve body, of the handle is sequentially provided with the spring and a pilot valve. Under the elastic force of the spring, the pilot valve port is plugged through the pilot valve. By the adoption of the one-way pressure-control tap water valve, water only can flow in one direction and is effectively prevented from flowing back, the water pressure can be adjusted, and water can be conveniently supplied to the occasions, such as a solar water heater and a roof water storage tank, with the high water pressure use requirement.
Description
Technical field
The present invention relates to reduction valve field, refer in particular to a kind of unidirectional pressure control running water valve.
Background technique
Solar water heater, roof water storage box etc. are placed on the top layer in house substantially; When hydraulic pressure is less, easily flow backwards when sending water, for this reason, we have developed a kind of unidirectional pressure control running water valve, make current can only one-way flow, effectively prevent aqueous reflux, and can regulate the pressure of water, be convenient to send water to solar water heater, roof water storage box etc.
Summary of the invention
The present invention seeks to provide a kind of unidirectional pressure control running water valve to overcome the deficiencies in the prior art, making current can only one-way flow, effectively prevent aqueous reflux, and the pressure of water can be regulated, be convenient to send water to solar water heater, roof water storage box etc.
For achieving the above object, the technical solution used in the present invention is: a kind of unidirectional pressure control running water valve, comprises two ends and arranges female valve body and be arranged on the valve pocket in valve body; One end of described valve pocket is fixed on the convex shoulder in valve body, and the inwall gap of all the other and valve body is arranged; Be disposed with by spool, the Returnning spring of valve pocket one end shaft shoulder location in described valve pocket and be fixed on the valve gap of the valve pocket the other end; Described spool is provided with damping hole; Described valve pocket is provided with weep hole with the overlapping of spool, and between spool and valve gap, is provided with pilot valve valve port; Described valve body is provided with one end to stretch in valve body and the handle be threaded connection; The described handle end stretched in valve body is disposed with spring and pilot valve, makes pilot valve block pilot valve valve port under the elastic force of spring.
Preferably, described valve pocket is threaded connection or is weldingly fixed on convex shoulder.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Unidirectional pressure control running water valve of the present invention makes current can only one-way flow, effectively prevents aqueous reflux, and can regulate the pressure of water, be convenient to have the occasion of high hydraulic pressure usage requirement to send water to solar water heater, roof water storage box etc.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is the structural representation of unidirectional pressure control running water valve of the present invention;
Wherein: 1, valve body; 2, valve pocket; 21, weep hole; 22, pilot valve valve port; 3, valve gap; 4, Returnning spring; 5, spool; 6, pilot valve; 7, spring; 8, handle.
Embodiment
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
Accompanying drawing 1 is unidirectional pressure control running water valve of the present invention, comprises the valve pocket 2 that two ends arrange female valve body 1 and are arranged in valve body 1; One end of described valve pocket 2 is threaded connection or is weldingly fixed on the convex shoulder in valve body 1, and the inwall gap of all the other and valve body 1 is arranged; Spool 5, Returnning spring 4 and valve gap 3 is disposed with in described valve pocket 2; Described spool 5 is provided with damping hole, and is located by the shaft shoulder of valve pocket 2 one end; Described valve gap 3 is threaded connection the other end being fixed on valve pocket 2, plays seal action; Described valve pocket 2 is provided with weep hole 21 with the overlapping of spool 5, and is provided with pilot valve valve port 22 between spool 5 and valve gap 3; Described valve body 1 is provided with one end to stretch in valve body 1 and the handle 8 be threaded connection; Described handle 8 end stretched in valve body 1 is disposed with spring 7 and pilot valve 6; Described pilot valve 6 blocks pilot valve valve port 22 under the elastic force of spring 7, makes current can only one-way flow.
During use: tap water enters from the water intake near damping hole, and enter in valve pocket 2 by damping hole, hydraulic pressure now in valve pocket 2 is identical with the hydraulic pressure of valve body 1 water intake, but weep hole 21 is blocked by spool 5, pilot valve valve port 22 is blocked by pilot valve 6, until when the hydraulic pressure of water intake is greater than the pressure of spring 7 setting, water in valve pocket 2 backs down pilot valve 6 automatically, hydraulic pressure now in valve pocket 2 is identical with the hydraulic pressure of valve body 1 water outlet, and hydraulic pressure in valve pocket 2 is lower than the hydraulic pressure of valve body 1 water intake, owing to there is pressure difference, the elastic force overcoming Returnning spring 4 slides to valve gap 3 by spool 5, the water of water intake flows into water intake by weep hole 21.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Unidirectional pressure control running water valve of the present invention makes current can only one-way flow, effectively prevents aqueous reflux, and can regulate the pressure of water, be convenient to have the occasion of high hydraulic pressure usage requirement to send water to solar water heater, roof water storage box etc.
Below be only embody rule example of the present invention, protection scope of the present invention is not constituted any limitation.The technological scheme that all employing equivalents or equivalence are replaced and formed, all drops within rights protection scope of the present invention.
