Description
Technical field
The utility model is related to a kind of one-way valve structures, particularly without the vertically arranged one-way cock for wanting spring.
Background technology
One-way cock has big application prospect due to having, and also there are many structures.If lift check valve is that one kind prevents
The valve that pipeline medium is flow backwards, is mainly made of associated components such as valve body, valve seat, flap, flaps.Lift check valve carries bullet
Spring, for ensuring flap under the action of the spring in the dynamic equilibrium, regardless of the pressure medium size at valve inlet end,
Valve energy balance movement, but can only be horizontally mounted；Lift check valve flap is also with guide rod, and guide rod is in the guiding of flap
Lifting is freely lifted in hole, when liquid injects in one direction, liquid is in the elastic force that flap pressure below is more than top, lifting
Formula check-valves flap rises on the sealing ring of valve, valve conducting, and conversely, flap is sealing when liquid injects above flap
It seals tightlier, therefore can not turn on ring.
When installing check-valves, it should be specifically noted that media flow direction, should make medium normal flow direction with referring on valve body
The arrow direction shown is consistent, otherwise will block the proper flow of medium.Bottom valve should be mounted on the bottom of pump sump pipeline.
The multiple industries of palpus need more preferable one-way cock more with industry, since existing one-way cock is generally suitable for water
Safety fills, and is restricted when in use more, and the functional reliability of the check valve of non-horizontal mounting can be greatly affected.
Utility model content
The utility model aim is to propose that one kind is suitable for vertically arranged gravity-held check valve, the work stress of valve
With flow evenly.Can be used for various fluids, including liquids and gases, the reliability of work greatly improves, and for woth no need to
The one-way cock of spring.
The technical solution of the utility model is a kind of gravity-held check valve door, it is characterized in that including valve body, valve import, list
To valve base, the outlet of valve, axis pin, flap, the one-way valve seat is an annulus on valve body, plane, that is, check valve of annulus
Valve seat planes are parallel with horizontal plane, and annulus is mounted in the center of the inlet and outlet runner of valve, flanged planar surface, that is, one-way valve of annulus
Seat Plane Installation flap, flap are the structure of clamshell doors, and each Men Jun is the cover board rotated freely around an axis pin in clamshell doors,
The each lower position of cover board when rotated is by one-way valve seat planes bound；By clamshell doors two during one-way valve seat planes bound
A cover board plane covers circular planes completely；Clamshell doors around two axis pins in the both sides of annulus.
The installation palpus right angle setting of the utility model, the course of work of the utility model, due to the flanged planar surface of annulus
With the horizontal plane angle of parallelism, flap is a cover board that placement is rotated freely around axis pin, cover board when rotated upper-lower position respectively by
Valve body wall and flanged planar surface limit；Circular planes are covered by cover board plane completely when being limited by flanged planar surface.Fluid is positive
During flowing, the pressure of fluid, which pushes flap cover board open, makes its rotation, and the aperture of the more big then cover board of pressure and flow of fluid is bigger；Stream
Body reverses through when, the pressure of fluid pushes flap to valve seat, and valve seat flap is all the more closed；The utility model is that need not have spring
Check valve；Reverse flow only needs to be sealed valve using flap gravity, and forward flow will not be subject to sealing influence or shadow
Sound is minimum.
Advantageous effect：As above operation principle understands that the work of the utility model is extremely reliable, can also ensure without spring
The work of check valve, saving spring part can make the structure of the utility model extremely simple, the reliability higher especially to work.
The utility model can be used for various fluids, including liquids and gases, can be used for requiring high MO sources valve.It is suitable for
Vertically arranged gravity-held check valve, the flap work stress and flow of the clamshell doors door of valve are evenly.
Description of the drawings
Fig. 1 is the utility model structure diagram.
Specific embodiment
As shown in the figure, valve body 1, valve outlet 2, flap free end 3 for concave shaped plate, the sealing joint strip 4 of flap, flap 5, valve
Body upper strip 6, axis pin 7, valve seat upper strip 8, one-way valve seat 9, valve import 10.
Gravity-held check valve door installs valve import, one-way valve seat, valve outlet, axis pin, flap, one-way valve on valve body
Seat is a Flange-shaped Parts hole seat, typically an annulus, and there are one the structure of the flanged planar surface of Flange-shaped Parts hole seat, flaps for tool
5 --- a pair of of gate-shaped structure, one around both sides, axis pin rotates freely on the door, and each door, which can be covered, to carry out in flanged planar surface to valve
Lid falls half, and the sealing after a pair of of door closure is good completely to valve is equipped with sealing joint strip 4 in the joint close position of door；Flap cover board is revolving
Upper-lower position respectively by valve body wall (valve body upper strip 6 hinders the shock of flap) and flanged planar surface restriction, (put down by Flange-shaped Parts when turning
Adhesive tape 8 also is provided in face, that is, valve seat planes)；When being limited by flanged planar surface flanged planar surface i.e. valve seat is covered completely on the door by one
Plane.Thickness, that is, weight of flap cover board is related with application, be usually 0.1-1mm or so stainless steel plate preferably, stainless steel plate
The flap cover board of preparation also is provided with axis hole with axis pin junction, and axis pin insertion flap plate shaft hole is equipped with one-way valve seat
Axis hole.This design is common design.
The improvement of the utility model is that each door of flap, that is, cover board includes a cover board for covering half of one-way valve seat
And the one piece of arc panel connected, one piece of arc panel is connected away from axis pin distalmost end on cover board, and arc panel is concave shaped plate (referring to attached
Figure).It can make the rigidity reinforcement of cover board, flap can be opened in time when having outflow fluid.
The simple modifications of principle based on the utility model are not departing from scope of the present application.
