Abstract
The utility model relates to an automatic check liquid valve, in particular to the valve is a liquid check valve depending upon water pressure for automatic closing and opening. The water tube and the valve for nowadays check valve are integrated which is difficult to manufacture and maintain. The automatic check valve will have a hole plate blank 1 to connect a seal plate 2 using soft band 3.The automatic check valve is more particularly fit for pumping pipe which is put vertically. The automatic check valve is positioned into the pumping pipe and the hole plate blank 1 is positioned at the lower and the seal plate 2 at the upper. When water is pumped the seal plate 2 is opened; when water is not pumped, water runs down automatically to press the seal plate 2 on the water-running hole 8 for automatic closing mode. The utility model has the advantages of elaborate structure designing, convenient maintaining and replacing and good sealing. The force of using water flow can realize closing and opening and is specially usefully for pumping pipe with head; after stopping pumping no irrigation is needed if pumping again.
Description
Technical field
The utility model relates to a kind of Liquid valve, specifically a kind of unidirectional Liquid valve by the hydraulic pressure recloser.
Background technique
The sealed core structure of existing hydraulic pressure one-way cock has two big classes: a class is that spring is arranged, and makes water valve produce the state that opens or closes with the elastic force of spring, can make valve be in the state of opposite pass (or opening) again by the hydraulic pressure spring.Another kind of is to make valve produce the state that opens or closes by the positive and negative direction of current entirely without spring.
Chinese patent 02279076.4 discloses a kind of one-way valve that spring is arranged, two sides at backing plate is established sealed tongue and spring respectively, valve rod passes the valve opening and the sealed tongue at backing plate center and fixes, when water flows to sealed tongue from spring, water flows to the sealed tongue direction from the water hole of backing plate valve opening periphery, the water hole that spring and water make sealed tongue be pressed in backing plate makes valve closing.If this one-way valve is used for water lift the lift water pipe is arranged promptly, the spring in this one-way valve is to belong to unnecessary setting.
Chinese patent 92107193.0 discloses a kind of one-way valve that does not have spring, establishes at the inwall of water pipe and supports the leakproof ring, flexibly connects with supporting the leakproof ring with the point at a water proof valve block edge, and certain that the water proof valve block is positioned at support the leakproof ring simultaneously.When water flowed to support leakproof ring from the water proof valve block, the water proof valve block was being supported on the leakproof ring this closed check valve by hydraulic pressure.When water flowed from opposite direction, the water proof valve block was dashed from supporting the leakproof ring, the one-way valve unlatching.This one-way valve water proof valve block links to each other with support leakproof ring in the water pipe, and water pipe and valve are one.
Summary of the invention
The purpose of this utility model provides a kind of can be placed between two pipe joints, and is abolishable again, the automatic one-way valve that leans on water (flow) direction to open or close automatically.
The structure of the automatic one-way valve of the utility model is: porose backing plate 1 is connected with soft band 3 with sealing plate 2.The hole of porose backing plate 1 is the water flow hole 8 of automatic one-way valve, and sealing plate 2 is to be used to seal water flow hole 8, so sealing plate 2 should be greater than water flow hole 8, and when a plurality of water flow hole 8, an available big sealing plate 2 hermetically sealed a plurality of water flow holes 8; Also but each water flow hole 8 is distinguished adapted sealing plates 2.When water when water flow hole 8 flows to sealing plate 2, sealing plate 2 because of soft band 3 no support forces then sealing plate 2 washed open automatically by water; Opposite when water when sealing plate 2 flows to water flow hole 8, sealing plate 2 is rushed at water flow hole 8 automatically by water, because of the position-limiting action of soft band 3, sealing plate 2 all seals water flow hole 8 and covers, the realization automatic-closing valve.This automatic one-way valve is particularly suitable for erectting the drinking-water pipe of placement, this automatic one-way valve is positioned in the drinking-water pipe of erectting placement, and porose backing plate 1 is following, sealing plate 2 is last, sealing plate 2 is opened when drawing water, and water is pressed in sealing plate 2 downwards automatically and becomes automatic closed condition on the water flow hole 8 when not taking out.Perfect construction design more below the utility model also has:
In order to make porose backing plate 1 and the water pipe good seal of putting automatic one-way valve, establish seal ring 4 at the edge of porose backing plate 1.Seal ring 4 is rubber Baltimore groove 5 packing rings, also can be rubber faced washer 9.Rubber Baltimore groove 5 packing rings are embedded in porose backing plate 1 outward edge in the Baltimore groove 5, and the water pipe periphery of clamping automatic one-way valve both sides like this can both seal.
Smooth tight for sealing plate 2 is covered on protruding ring 6, at hole backing plate 1 attachment post 7 of a little higher than protruding ring 6 is set, big centre, attachment post 7 two is little, and the rubber positioning ring 10 of soft band 3 can not dropped out in the middle of being stuck in attachment post 7.Soft band 3 is connected with attachment post 7, than with the direct-connected better tightness of plate face of porose backing plate 1.General porose backing plate 1 and sealing plate 2 are connected to good with two soft bands 3, the switch accurate positioning.Also available one or more soft band 3 connects.Be connected with soft band 3 with attachment post 7, then attachment post 7 matches with the quantity same position of soft band 3.
When a plurality of water flow hole 8, an available big sealing plate 2 hermetically sealed a plurality of water flow holes 8; Also but each water flow hole 8 is distinguished adapted sealing plates 2.
The porose backing plate 1 and the sealing plate 2 best Placements of the automatic one-way valve of the utility model are: soft band 3 is integral with sealing plate 2, be the extension that soft band 3 is sealing plates 2, the terminal positioning ring 10 of soft band 3 is socketed in the groove of the attachment post 7 on the porose backing plate 1.Material selection is that porose backing plate 1 is good with rigid plastics, also available metal; Sealing plate 2 and soft band 3 are used rubber, also available flexible plastic.
The utility model structural design is ingenious, and easy-maintaining is easily changed, and good airproof performance is realized switch automatically with the strength of current, is specially adapted to the water pipe that draws water of lift, draws water again behind stop pumping water again and need not pour water.
