The working life such as daily life action, study, work, leisure, social, amusement, personal lifestyle, family life and social life with
And ponder life.In order to preferably live, everyone must work hard for we.The value of life is in view of live system
Individual important category, value " concrete " is showed in view of live field.In a sense, the value of life is the meaning of life,
Assessment life " magnitude of value " size, it is possible to understand that how is the meaning of life, understands life significance size.Life is higher than surviving
A kind of state of aspect, is also a kind of optimistic attitude of life.
Leakage-preventing check valve is a kind of pipeline valve for being widely used in the water systems such as city, family, and it would generally be with
Apparatus for metering fluids in tubing is attached, such as water meter, due to the problem of water meter sensitivity, when the stream of water in pipeline
During amount very little, water meter cannot just carry out accurate metering；Meanwhile, if manifold pressure can cause water meter to count when fluctuating again；Cause
This, just can be avoided the occurrence of well above-mentioned using leakage-preventing check valve.Existing check-valves in use cannot
Impurity in water is filtered, and sealing is poor, using leakage is susceptible to after a period of time, causes troublesome poeration, it is difficult to
Meet the demand of people.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided a kind of leakage-preventing check valve.
This utility model is to be achieved through the following technical solutions：
A kind of leakage-preventing check valve, including valve gap, are threadedly coupled between the valve gap and valve body, set on described valve gap one end
The first inlet opening is equipped with, the valve body side is provided with the second inlet opening, and the valve body center is provided with the axis of guide, described
The axis of guide is connected with guide grab, is provided with returning spring between the axis of guide and guide grab, the guide grab and valve body it
Between be provided with sealing ring A and sealing ring B, the guide grab end is provided with wearing layer, and the valve gap is internally provided with drainage screen A
With drainage screen B.
Used as optimal technical scheme of the present utility model, the sealing ring A, sealing ring B are embedded on guide grab.
Used as optimal technical scheme of the present utility model, the sealing ring A, sealing ring B are O-ring seals.
As optimal technical scheme of the present utility model, the drainage screen A, the curved convex shapees of drainage screen B, and filter essence
Degree is different.
Compared with prior art, the beneficial effects of the utility model are：This utility model simple structure, it is reasonable in design,
By arranging sealing ring A, sealing ring B, drainage screen A and drainage screen B, when using, check-valves can be played preferably this utility model
Anti-leak function, while can realize filtering the impurity in water in the presence of drainage screen A and drainage screen B, effectively
Raising water quality, and sealing ring A, sealing ring B can improve the sealing of guide grab, extend the service life of valve body, full
The demand of sufficient people.
Description of the drawings
