Abstract
The utility model relates to a running water pressure control discharge valve, which comprises a a valve body, a water inlet, a water outlet, and an end cover. The utility model is characterized in that the front end of an inner cavity pipe has a film piston component fixed on the valve body, one end of a spring is connected with the film piston component, and the other end is fixed at a fixing pin of the front end of the end cover; the end cover is communicated with a two-position three-way valve having breathing holes, one end of a nonreturn valve is connected with the two-position three-way valve, and the other end is connected with the inlet and the outlet of a running water pipe. The utility model has the advantages of no need of special power sources, the convenient source of working mediums, reliable performance, long service life, low cost, good sealing effect, and strong sewage discharging ability, and the utility model can be used for water sealing and discharging places having the need of middle and low water head, and high flow rate.
Description
The utility model be use a kind of very widely in, the low-pressure drainage sealing water device.
At present, along with automatic control technology day by day gos deep into the every field of national economy, also by a large amount of employings,, be widely used in fields such as chemical industry, papermaking, printing and dyeing, washing plant especially especially from control draining valve as the Self controlling valve of important self controlled element.But, as current automatically controlled drain valve, gas control drain valve from the control draining valve main body generally be faced with complex structure, cost an arm and a leg, defective such as bulky, especially automatically controlled drain valve will be joined motor special, the gas control drain valve will be joined special air compressor, improve the user cost of its single-piece greatly, seriously hindered popularizing of itself.
The purpose of this utility model is to make a kind of simple in structure, convenient and reliable automatic control water shutoff drainage means.Its working medium convenient sources, pressure stability, and with low cost; The film piston action is reliable rapidly, the life-span is long.When taking into account the gentle control draining valve advantage of automatically controlled drain valve, remedied its user cost height, expensive defective again, can be widely used in every field such as washing plant, papermaking, printing and dyeing, chemical industry.
Technical solution of the present utility model is: drain valve is communicated with the use in washing machine screw is fastening by the flange on the valve body.The pipe front end has the film piston assembly that is fixed on the valve body in the chamber of valve body, and spring one end links to each other with the film piston assembly, and the other end is fixed on the spring fixing pin of end cap front end.Be communicated with the two position three-way valve of being with spiracle at the end cap front end, one-way valve one end is connected with two position three-way valve, and the other end has the interface that joins with running water pipe (or other self is with the baric flow body source).Tap water (perhaps its itself fluid with pressure), enter in the setting-out chamber of forming by film piston assembly and end cap via interface, one-way valve, two position three-way valve, rely on the pressure of himself, press the film piston assembly, make its front end that is pressed on pipe in the valve body chamber, carry out water shutoff.When the spiracle of two position three-way valve was opened, the high pressure water in the setting-out chamber was communicated with atmosphere, discharged himself pressure of being with, and spring relies on its restoring force, drove the front end that the film piston assembly leaves pipe in the valve body chamber, carried out draining.In addition, adopt one-way valve to keep the pressure stability of tap water (or other self is with hydraulic fluid), eliminate the influence of its pressure surge, and be provided with the manual drainage valve, near the valve body drain opening, be provided with dirt guiding groove at the downside of end cap to water sealing effect.
According to technique scheme, this installs, and each piece volumes is little, simple in structure, cheap, good sealing effect, pollution discharge capability are strong, wherein, and with tap water (or its itself fluid with pressure) medium of working, convenient sources, with low cost, flexibility and reliability; Keep the working medium pressure steady fixed with one-way valve; Can realize automatic control with two position three-way valve; Can realize manually-operable with manually-operated gate; Itself is provided with dirt guiding groove valve body, makes dirt be difficult for accumulating.The utility model is compared with prior art: this device applicability is strong, and the working medium convenient sources is reliable, and self structure is simple, can be big, can be little, and each component costs is cheap, and good reliability is applicable to every field such as washing machine equipment, printing and dyeing, papermaking, chemical industry.
Accompanying drawing is the utility model structure cross-sectional schematic.
With reference to the accompanying drawings, embodiment of the present utility model is described as follows:
This device mainly comprises valve body, advances drain opening, film piston assembly, spring, end cap, two position three-way valve, one-way valve, manually-operated gate.The usefulness screw is fastening is communicated with by the flanged surface on the valve body 2 and washing machine 1 for drain valve.The pipe front end has the film piston assembly 3 that is fixed on the valve body 2 in the chamber of valve body 2, and spring 4 one ends link to each other with film piston assembly 3, and the other end is fixed on the spring fixing pin 6 of end cap 5 front ends.Be communicated with the two position three-way valve 7 of band spiracle at end cap 5 front ends, one-way valve 8 one ends are connected with two position three-way valve 7, and the other end has the interface 9 that links to each other with running water pipe (or other self fluid source with pressure).Tap water 10 (perhaps its itself fluid with pressure) enters in the setting-out chamber of being made up of film piston assembly 3 and end cap 5 via interface 9, one-way valve 8, two position three-way valve 7, rely on the pressure of himself, press film piston assembly 3, make it be pressed on the front end of pipe in valve body 2 chambeies, carry out water shutoff.When the spiracle of two position three-way valve 7 was opened, the high pressure water in the setting-out chamber was communicated with atmosphere, discharged himself pressure of being with, and spring 4 relies on its restoring force, drives the front end that film piston assembly 3 leaves pipe in valve body 2 chambeies, carries out draining.
In addition, keep the pressure stability of tap water (or other self is with hydraulic fluid), eliminate the influence of its pressure surge water sealing effect with one-way valve 8.Be provided with manual drainage valve 11 at end cap 5 downsides, can realize manually-operable.Near valve body 2 drain opening, be provided with dirt guiding groove 12, strengthened pollution discharge capability.
Its medi-spring, two position three-way valve, manually-operated gate etc. adopt outsourcing piece; Valve body and end cap are formed by casting on request, through after the machining processes, and surface spraying aluminium paint; The rubber film piston is formed by the mould compacting on request.
