For the ease of filtering larger impurity, prevent from blocking stream, as preferably, described filter screen is provided with several filtering hole, and the diameter of described filtering hole is 3 ~ 5mm, and the spacing of adjacent two described filtering hole is 5mm.
Beneficial effect: the utility model utilizes the hinged rotation of catch and the effect of return spring, ensure that the traffic organising in valve body, adds filter screen and can to disappear deimpurity impact, reduce the loss of catch, also can ensure the stability of traffic organising.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the plan view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As depicted in figs. 1 and 2, the utility model is made up of valve body 1 and three air outlet holes etc., air passing hole is provided with in described valve body 1, three described air outlets are all connected through with air passing hole, a valve pocket 2 is provided with in each described air outlet, the middle part of described valve pocket (2) appearance is provided with the annular boss (21) of one machine shaping, described annular boss (21) is equipped with a groove of cooling down with the both sides root of valve pocket (2) joint, is all embedded with seal ring (5) described in each in groove of cooling down; One end of described valve pocket 2 is spirally connected and is fixed on air outlet, and the side of each described valve pocket 2 inner chamber is equipped with filter screen 3, and described filter screen 3 is provided with several filtering hole, and the diameter of described filtering hole is 3 ~ 5mm, and the spacing of adjacent two described filtering hole is 5mm.
The opposite side of described inner chamber is equipped with three catch, 4, three described catch 4 and evenly arranges along the inwall of valve pocket 2, and each described catch 4 is all triangular in shape, and mutually abut between adjacent two described catch 4, three described catch 4 are all in same level; A limit of each described catch 4 is all suitable and hinged fixing with the shape of valve pocket 2 inwall corresponding position, the side of each described catch 4 is provided with the limit spring 6 keeping catch level, one end of described limit spring 6 and the respective side of catch 4 are connected and fixed, and valve pocket 2 inwall of the other end and corresponding position is connected and fixed.
Using method of the present utility model is as follows:
As shown in Fig. 1 to Fig. 2, three valve pockets 2 are spirally connected respectively to be fixed on three air outlets corresponding on valve body 1, each side of valve pocket 2 upper annular platform 21 abuts with the air outlet hole outer wall end face of valve body 1 corresponding position, seal ring 5 all screws in air outlet hole, connect the valve pocket 2 of gas or liquid inflow direction, the side and valve body 1 that are provided with filter screen 3 are spirally connected fixing, outside the side being provided with catch 4 is stretched to, the valve pocket 2 of all the other both directions of valve body 1, then being spirally connected the side being provided with catch 4 is fixed on valve body 1, when when gas or liquid, the valve pocket 2 through ingress arrives catch 4 position of corresponding position, due to catch 4 being installed with limit spring 6, and limit spring 6 plays is the effect keeping catch 4 level, mutually abut between three adjacent catch 4, when pressure is less than the elastic force of limit spring 6, gas or liquid cannot wash the plane of the similar baffle plate that three catch 4 are formed open, namely the barrier functionality of one-way valve is realized, when pressure is greater than the elastic force of limit spring 6, limit spring 6 is shunk, catch 4 is under the pulling of limit spring 6, centered by hinged place, the flow direction along gas or liquid rotates, so just form opening, gas or liquid enter in valve body 1 immediately, under pressure, wash the catch 4 on correspondence direction valve pocket 2 successively open, and flow out from the air outlet hole of correspondence direction, after liquid or gas conveying put in place, pressure reduces, and limit spring 6 promotes catch 4 return, again the air outlet hole of airtight valve pocket 2.
In these cases, the impurity in gas or liquid can be trapped between catch 4 and filter screen 3; If also installed according to the mode of the valve pocket 2 of inflow direction flowing out the valve pocket 2 in direction, namely the side and valve body 1 that are provided with filter screen 3 are spirally connected fixing, outside the side being provided with catch 4 is stretched to, the impurity in gas or liquid is trapped between catch 4 and filter screen 3 too.
Accordingly, side as three valve pockets 2 are provided with catch 4 is spirally connected to be fixed on and stretches on valve body 1, and gas or liquid first enter in valve body 1 via filter screen 3 again, and impurity then accumulates on filter screen 3, be convenient to cleaning, a small amount of small-sized impurity still can be trapped between catch 4 and filter screen 3.
In sum, the utility model is easy for installation, uses flexibly, applied widely.
It is consistent with prior art that the utility model does not describe part, and therefore not to repeat here.
These are only mode of execution of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure utilizing the utility model specification and accompanying drawing content to do; directly or indirectly be used in the technical field that other are relevant, all in like manner within scope of patent protection of the present utility model.
