Abstract
The utility model relates to a novel check valve which comprises a tapered valve body. A movable piston is arranged in a tapered hole of the bottom of the valve body, the piston is in a tapered structure, the taper of the piston is identical to the taper of the valve body, the piston is matched with a tapered surface of the valve body, a first hook is arranged at the bottom of the piston, a second hook is arranged on the outside of the valve body, and the first hook and the second hook are connected through a string. According to the novel check valve, the tapered hole is formed in the valve body, the tapered piston is arranged in the tapered hole of the valve body, and the piston and the valve body are connected through the string, so that when water is fed, the piston is pushed open and cannot be blown away as the piston and the valve body are connected through the string, and during checking, the tapered hole at an inlet of the valve body is matched with the piston through the tapered surface, so that the check effect is guaranteed.
Description
Technical field
The utility model relates to a kind of non-return valve.
Background technique
Traditional check valve structure complexity, manufacture cost is higher, and the non-return effect also can go down to some extent after long-time the use.
The model utility content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, a kind of non-return valve is provided, simple in structure, the non-return effect is superior.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of non-return valve, comprise tapered valve body, the taper hole of described valve body bottom is provided with mobilizable piston, the tapered structure of described piston, the tapering of described piston is identical with the tapering of valve body, the cone match of described piston and valve body, and the bottom of described piston is provided with first hook, the outer installment of described valve body has second hook, and described first hook links together by cord with second hook.
Further, described piston adopts rubber to make.
The beneficial effects of the utility model are: be taper hole in the valve body, the piston of a taper is set in the taper hole of valve body, link together by cord between piston and the valve body, during water inlet, piston is open, owing to there is cord to be tied together, so piston can not be blown away, when non-return, the taper hole of the inlet of valve body and piston phase cone match are guaranteed the non-return effect.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is structural representation of the present utility model;
Wherein: 1, valve body, 2, piston, 3, cord.
Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic representation that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
As shown in Figure 1, a kind of non-return valve, comprise tapered valve body 1, the taper hole of valve body 1 bottom is provided with mobilizable piston 2, piston 2 tapered structures, and the tapering of piston 2 is identical with the tapering of valve body 1, the cone match of piston 2 and valve body 1, the bottom of piston 2 is provided with first hook, and the outer installment of valve body 1 has second hook, and first hook links together by cord 3 with second hook.For improving the non-return sealing effect, piston 3 adopts rubber to make.
Be taper hole in the valve body 1, the piston 2 of a taper is set in the taper hole of valve body 1, link together by cord 3 between piston 2 and the valve body 1, during water inlet, piston 2 is open, owing to there is cord 3 to be tied together, so piston 2 can not be blown away, when non-return, the taper hole of the inlet of valve body 1 and piston 2 phase cone match are guaranteed the non-return sealing effect.
Be enlightenment with above-mentioned foundation desirable embodiment of the present utility model, by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this model utility technological thought.The technical scope of this model utility is not limited to the content on the specification, must determine its technical scope according to the claim scope.
