Abstract
The utility model relates to a liquid valve, comprising a valve cavity with a water outlet, a water inlet tube with an end port inside the valve cavity and a valve flake. The utility model is characterized in that the end port of the water inlet tube inside the valve cavity is elliptic; the closed valve flake of the elliptic end port can be hinged with the end port or the inner wall of the valve cavity after rotation; the angle between the plane of the elliptic port and the cross section of the water inlet tube is the angle between the cross section of the water inlet tube and the vertical plane after the installation of the valve plus zero to forty-five degrees. An adjusting bolt which can adjust the valve flake into the biggest opening angle exteriorly and an observation port which can observe the transparency and sealing of the valve flake are better arranged on the valve cavity wall. The utility model has the advantages of providing a return and self-closing valve for liquid to pass through smoothly if only the liquid has small positive pressure, in order to meet the requirements of specific applications, for example, to meet the requirements of solar water heating system to realize the composite circulation by natural circulation and forced circulation.
Description
Technical field
The utility model is a kind of Liquid valve, is specially adapted to use in the cocycle pipeline of solar water-heating system.
Background technique
Existing various backflow self closing stop valve, or claim check valve, one-way valve, the positive pressure that all needs liquid to have certain intensity could be pushed its valve block open, and liquid also could pass through smoothly.But in some application, the positive pressure of liquid is very little, is difficult to valve block is pushed open.For example in the cocycle pipeline that is tilted to of solar water-heating system, just in the pipeline that is tilted to that the upper cycling mouth that makes heat collector is communicated with cyclic water tank top, need to be connected in series a backflow self closing stop valve sometimes.This valve is in parallel with a pump circulation water pump, and the forward of valve is the direction to cyclic water tank top from the upper cycling mouth of heat collector, and the pump circulation water pump is electrically connected with the electric controller that has temperature transducer, to realize the combined cycle of natural circulation and pump circulation composition.When heat collector heat absorption after a little while, water temperature is lower, the pump circulation water pump is not worked, hot water is natural circulation, flows out, enters cyclic water tank top through upper circular tube and backflow self closing stop valve from the upper cycling mouth of heat collector.When heat collector absorbs heat for a long time, the water temperature height, the electric controller that has temperature transducer makes the pump circulation water pump connect power supply, water pump operation, the reverse pressure of water pump water delivery is closed the backflow self closing stop valve, this moment, hot water was pump circulation, sent into cyclic water tank top from upper cycling mouth outflow, process upper circular tube and the pump circulation water pump of heat collector.Thereby strong at sunlight, when natural circulation can not effectively be worked, pump circulation starts automatically, improves operational efficiency; Because pump circulation is located on the cocycle pipeline as bypass, under the pump circulation state, the stratification state of high and low warm water can be not destroyed in the heat collector, can not cause cold and hot water to mix, therefore come-up hot water in the heat collector can have been improved the useful thermal efficiency under the pump circulation state greatly by preferential, layering sucking-off.But this technological scheme is existing backflow self closing stop valve as if what use, and is small from the heat hydraulic pressure that the heat collector upper cycling mouth flows out at the natural circulation state, the valve block of backflow self closing stop valve can not be pushed open at all.
Summary of the invention
The purpose of this utility model provides a kind of needs liquid to have the backflow self closing stop valve that very little positive pressure just can be passed through smoothly.
The utility model backflow self closing stop valve includes the valve chamber of taking the mouth of a river out of, intake pipe and the valve block of one port in valve chamber, it is characterized in that the port of intake pipe in valve chamber is for oval, the one frivolous valve block that can make this elliptical ports sealing after rotating is with this port is hinged or hinged with the valve chamber inwall, the angle of plane, elliptical ports place and intake pipe cross section for after this valve installation, the angle of intake pipe cross section and vertical guide increase again 0 ° of ∠～≤ 45.Be preferably in the valve pocket body wall and be provided with and adjust the adjusting bolt of valve block maximum opening from the outside, and be provided with the observation panel that to observe the transparent of valve block and sealing.Because regardless of this valve the acclivitous degree in back is installed, when frivolous valve block was in the position of occluded ellipse port, its center of gravity all departed from vertical line, therefore under the gravity torque effect, valve block is often opened.In case and when in the valve chamber reverse water pressure being arranged, frivolous valve block just counter-rotating immediately makes elliptical ports airtight.
The beneficial effects of the utility model are for satisfying the requirement of particular application, as realizing the requirement of natural circulation and pump circulation composition combined cycle for satisfying solar water-heating system, provide a kind of to need liquid to have very little positive pressure, the backflow self closing stop valve that liquid itself just can pass through smoothly.

Fig. 2 is the structural representation of A-A section among Fig. 1.
Embodiment
See the embodiment of Fig. 1 and 2, be used for the cocycle pipeline that is tilted to of solar water-heating system.The port of intake pipe 1 in valve chamber 2 is oval, and the frivolous valve block 3 of corrosion resistant alloy of this elliptical ports sealing is articulated on the port by twisted axis 4.After valve was installed on upper circular tube, the angle of cut α of elliptical ports place plane L and intake pipe cross section M was that the angle β of M and vertical guide N increases by 4 degree (having done exaggerative expression among Fig. 1) again.The wall of valve chamber 2 is provided with the adjusting bolt 5 that can adjust valve block 3 maximum openings from the outside.6 is water outlet among the figure, and 7 are assembling bolt, and 8 is guide plate, and 9 for hanging the stream plate, and 10 is the seal ring that elliptical ports studded with.The effect of guide plate 8 and extension stream plate 9 is the sloughs of reducing in the valve chamber 2, to reduce fluid resistance.Valve chamber 2 is provided with the transparent sealing observation panel that can observe valve block 3, so that the adjustment of valve block 3.Observation panel is made up of detector tube 11, perspective piece 12, seal ring 13 and visor gland 14.
Above embodiment is only in order to be further described the utility model, and scope of the present utility model is not subjected to the limitation of illustrated embodiment.
