Description
Technical field
The utility model is related to valve body equipment technical fields, are specially Double-disc type metal sealing check valve.
Background technology
Check valve is that fluid can only be flowed along fluid inlet, and fluid outlet medium can not but flow back, and be commonly called as check valve, unidirectionally
Valve is also known as check-valves or non-return valve.For preventing oil stream reverse flow in hydraulic system, or for preventing from pressing in pneumatic system
Contracting air reverse flow has in present mechanical equipment and has been widely used, but present check valve is typically necessary outside
Portion's driving device braking cut-out pipeline internal medium, ensures that medium can only be flowed from a direction, saves because pressure change causes back
The medium of stream, but external driver device is installed and so that the structure of check valve is excessively complicated, it is not easy to install, also increases device
Production cost.
Utility model content
The technical problems to be solved in the utility model is the defects of overcoming the prior art, and it is unidirectional to provide Double-disc type metal sealing
Valve.
In order to solve the above-mentioned technical problem, the utility model provides following technical solution：Double-disc type metal sealing list
To valve, including silently, main shaft, gasket seal A, axle sleeve, spring, valve plate, valve body and gasket seal B, the interposition of the valve body
It installs and is equipped with circular hole, and main shaft is provided in the circular hole of valve body, be equipped with silently in the circular hole of the valve body both sides, and valve body
Horizontal cross sectional geometry is circle, and the centre position of the main shaft is equipped with axle sleeve, and spring is fixedly connected with axle sleeve, the spring
It is fixedly connected with the one side of valve plate, and the junction of valve plate and spring is provided with the company of gasket seal A, the main shaft and valve body
The place of connecing is provided with gasket seal B.
Preferably, it is to be flexibly connected between the main shaft and axle sleeve.
Preferably, the valve body and valve plate are stainless steel metal material members, and the cross sectional shape of valve plate is circle.
Preferably, valve plate section diameter of a circle is less than the diameter of section of valve body centre bore, and the edge peace of valve plate
Equipped with gasket.
Preferably, the length of the main shaft is less than the maximum gauge of valve body.
The advantageous effect that the utility model is reached is：Using internal pipe pressure valve plate is promoted to rotate so that medium leads to
It crosses, when inlet pressure is less than in the case of downstream pressure, valve plate can be closed moment, cut off media flow, and whole process automatically adjusts,
Without external driver device, the structure of device is greatly simplified, facilitates the installation of device, while in the connection of valve plate and main shaft
The junction of place, main shaft and valve body is respectively arranged with gasket seal A and gasket seal B so that device has higher leakproofness
Can, effectively avoid valve port leakage, function admirable.

Specific embodiment
The preferred embodiment of the utility model is illustrated below in conjunction with attached drawing, it should be understood that described herein excellent
Embodiment is selected to be only used for describing and explaining the present invention, is not used to limit the utility model.
Embodiment 1
As shown in Figs. 1-2, Double-disc type metal sealing check valve, including silently 1, main shaft 2, gasket seal A3, axle sleeve 4, bullet
Spring 5, valve plate 6, valve body 7 and gasket seal B8, the centre position of valve body 7 are provided with circular hole, and main function guarantee is connected with pipeline,
It accepts trim and upper cover position is fixed, and main shaft 2 is provided in the circular hole of valve body 7, be equipped in the circular hole of 7 both sides of valve body
Silently 1, sealed valve body 7 prevents medium from leaking outside, and the horizontal cross sectional geometry of valve body 7 is circle, the centre position installation of main shaft 2
There is axle sleeve 4, and spring 5 is fixedly connected with axle sleeve 4, spring 5 is fixedly connected with the one side of valve plate 6, and valve plate 6 and spring 5
Junction is provided with gasket seal A3, and noise reduction reduces friction, cushioning effect, and main shaft 2 and the junction of valve body 7 are provided with sealing
Gasket B8, connection valve plate 6 and valve body 7, and fixed relative position, to be flexibly connected between main shaft 2 and axle sleeve 4, valve body 7 and valve plate
6 be stainless steel metal material members, and the cross sectional shape of valve plate 6 is circle, and 6 section diameter of a circle of valve plate is less than 7 center of valve body
