Description
Technical field
The present invention relates to the startup of a kind of check valve, be specifically related to the integral type check valve of a kind of low startup force value.
Background technology
Check valve is that fluid can only flow along water inlet, a kind of device that outlet medium but cannot reflux.Check valve is again
Claim check-valves or non-return valve, in hydraulic system, prevent oil stream reverse flow, or in pneumatic system, prevent compression sky
Gas reverse flow, is divided by structure: lift check valve, butterfly check valve, swing type check valve；Lift check valve: vertical
Check valve, horizontal check valve；Swing type check valve: single-lobe formula check valve, Double-disc type check valve, multi-clove type check valve.By connecting
Form divides: threaded check valve, welding check valve, flange check valve, check valve has through type and right-angle type two kinds, straight-through
Formula check valve is arranged on pipeline with threaded, and angle check valve has connection threaded, board-like and flange three kinds connection
Mode.
Starting pressure and refer to the pressure of switch open moment, the pressure just opened is exactly the startup pressure of this check valve, existing
Some check valve inlet openings are directly connected with switching device, are a straight-through pipeline, and water shortage or water velocity are little
In the case of, often do not reach the startup force value of check valve, it is difficult to start non-return valve operational.
Summary of the invention
The technical problem to be solved is the startup stress problems of check valve, it is therefore intended that provide a kind of low startup
The integral type check valve of force value, solves the problem that check valve can not start in the case of pressure is little.
The present invention is achieved through the following technical solutions:
The integral type check valve of a kind of low startup force value, including valve body, valve body flows to radial symmetric, valve inner about liquid
One cavity is set, flows to direction according to liquid in cavity, have valve head, inlet opening, pressure chamber, switching device, spring successively,
Inlet opening is radially disposed in valve head interior, and valve head is close to valve interior wall side, and pressure chamber one end is connected with inlet opening, and the other end withstands on
On switching device, on the switchgear, the other end withstands on valve seat on spring one end top, in the prior art, and traditional check valve
Inlet opening is directly connected with switching device, be a straight-through pipeline, water shortage or water velocity little in the case of, past
Toward the startup force value not reaching check valve, it is difficult to start non-return valve operational, the invention provides a kind of low startup force value
Integral type check valve, uses pressure chamber structure, increases water volume, and water reaches certain volume will form a force value, opens
Dynamic non-return valve operational, well solves the problem that tradition check valve can not start in the case of pressure is little.
Inlet opening is cylindrical, and cylinder has good tension stress and compressive resistance, can increase the concentration degree of water, will not
Four sides diffusion, thus a bigger force value is provided, it is provided that start the startup force value of check valve.
Cylindrical diameter is less than the width of pressure chamber, only when cylindrical diameter is less than the width of pressure chamber, current
Entering pressure chamber can store, the storage force value along with water is also gradually increased, the when of reaching to start force value, and check valve
Will start.
Spring is compressive state, and spring is a kind of machine components utilizing elasticity to carry out work, zero made with elastomeric material
Part deforms upon under external force, and removing restores to the original state again after external force provides enough force value, the spring of compression to baffle plate
There is force value, allow switching device be close on pressure chamber, stop liquid reverse flow.
The present invention compared with prior art, has such advantages as and beneficial effect:
1, the integral type check valve of a kind of low startup force value, including valve body, valve body is to flow to radial symmetric, valve body about liquid
Inside arranges a cavity, flows to direction according to liquid in cavity, have successively valve head, inlet opening, pressure chamber, switching device,
Spring, inlet opening is radially disposed in valve head interior, and valve head is close to valve interior wall side, and pressure chamber one end is connected with inlet opening, another
On the switchgear, on the switchgear, the other end withstands on valve seat on spring one end top, in the prior art, traditional on end top
Check valve inlet opening is directly connected with switching device, is the little feelings of a straight-through pipeline, water shortage or water velocity
Under condition, often do not reach the startup force value of check valve, it is difficult to start non-return valve operational, the invention provides a kind of low startup and press
The integral type check valve of force value, uses pressure chamber structure, increases water volume, and water reaches certain volume will form a pressure
Value, starts non-return valve operational, well solves the problem that tradition check valve can not start in the case of pressure is little.；
2, the integral type check valve of a kind of low startup force value of the present invention, cylindrical diameter is less than the width of pressure chamber, only
When cylindrical diameter flows into pressure chamber can store less than the width of pressure chamber, water, along with water storage force value also
Being gradually increased, the when of reaching to start force value, check valve will start；
3, the integral type check valve of a kind of low startup force value of the present invention, spring is compressive state, and spring is a kind of utilization elasticity
Carrying out the machine components of work, the part made with elastomeric material deforms upon under external force, recovers again former after removing external force
Shape provides enough force value to baffle plate, and the spring of compression has force value, allows switching device be close on pressure chamber, stops liquid
Body reverse flow.
