Abstract
The utility model relates to the technical field of check valves, in particular to a check valve with an improved valve plate. The check valve comprises a valve body, a connecting rod and the valve plate, and is characterized in that the connecting rod and the valve plate are integrated; and the outer side surface of the valve plate is a circular arc surface. Compared with the prior art, the utility model has the characteristics of simple structure, good stability and airtightness, and long service life.
Description
[technical field]
The utility model relates to the safety check technical field, a kind of specifically safety check that improves valve plate.
[background technique]
Safety check is used quite extensive at home at present, but most safety check is after long-time the use, the valve plate of circular plate type all can deform or damage, thereby causes valve body that phenomenons such as leakage take place, and this is to cause because valve plate is subjected to the pressure of medium for a long time.
[summary of the invention]
The purpose of this utility model is in order to overcome the deficiencies in the prior art, to have improved the valve plate moulding, and it is good to have improved stability and airtight performance, increases the service life.
To achieve these goals, designed a kind of safety check that improves valve plate, comprised valve body, connecting rod, valve plate, it is characterized in that: connecting rod and valve plate are integral type, and the outer side surface of valve plate is an arc surface.
The piston part of described valve plate and the surface of contact of valve body are provided with seal ring.
The utility model is compared with prior art, and is not only simple in structure, good stability and to have an airtight performance good, the characteristics of long service life.
[description of drawings]
Fig. 1 is the utility model structural representation.
Referring to Fig. 1,1 is connecting rod; 2 is valve plate; 3 is valve body; 4 is seal ring.
[embodiment]
Below in conjunction with accompanying drawing the utility model is further described.
Referring to Fig. 1, medium enters the runner on valve body 3 left sides, valve plate 2 and connecting rod 1 are subjected to after the thrust of medium by jack-up, make medium flow into the runner on valve body 3 the right, when the medium stop motion, because the gravity of connecting rod 1 lower end is greater than the top, make valve plate 2 and connecting rod 1 close runner with regard to freely falling, having finished medium only flows to a direction, and stoped process of flowing in the other direction, outer side surface because of valve plate 2 is an arc surface again, so can better pressure medium be disperseed, causes distortion and damage because of pressure is excessive thereby reduced valve plate 2.
Claims (2)
1. a safety check that improves valve plate comprises valve body, connecting rod, valve plate, it is characterized in that: connecting rod (1) is an integral type with valve plate (2), and the outer side surface of valve plate (2) is an arc surface.
2. a kind of safety check that improves valve plate as claimed in claim 1 is characterized in that: the surface of contact of the piston part of valve plate (2) and valve body (3) is provided with seal ring (4).
