Description
Technical field
The utility model relates to a kind of one-way valve with pooling feature.
Background technique
One-way valve be fluid can only one direction flow and position control valve that can not reverse flow.Its working principle is that fluid enters from import, overcomes spring force and frictional force one-way valve valve port is opened, and fluid flow to outlet from import; When import is during without fluid, under spring force and outlet fluid pressure action, valve port is in closed condition, makes from being exported to inlet ductwork obstructedly, and one-way valve is applied to not allow the occasion of reverse fluid flow.
After after general one-way valve pressurized, pressure is greater than spring force, one-way valve moves, valve core opening is to connecting pipeline after certain value, but when in pipeline, compression shock, force value change, the easy discontinuous circuit pressure pulse big rise and fall of one-way valve action, the one-way valve life-span declines thus greatly, and the stability of one-way valve can not be protected.

The utility model one-way valve available buffer compression shock, effectively extends one-way valve life-span guarantee one-way valve stability.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1-valve body, 2-mounting nuts, 3-fluid inlet, 4-fluid output, 5-step, 6-the first cavity, 7-the second cavity, 8-the first spool, 9-the first spring, 10-the second spool, 11-the second spring, 12-7 type damping hole, 13-conical damping hole.
Embodiment
Below in conjunction with Figure of description, the utility model is described in further detail:
A kind of one-way valve with pooling feature, comprise valve body 1 and mounting nuts 2, valve body 1 one end and mounting nuts 2 threaded, regulate mounting nuts 2 can regulate the force value of one-way valve, and then meet the use of different occasions, valve body 1 the other end arranges fluid inlet 3, and body wall arranges fluid output 4, valve body 1 inwall is provided with step 5, step 5 is separated into the first cavity 6 and the second cavity 7 by body cavity, interior the first spool 8 and the first spring 9 of arranging of the first cavity 6, the first spring 9 is between the first spool 8 and mounting nuts 2, the stressed meeting of the first spool 8 is to the first spring 9 compressions, pressure reduces the first spring 9 can promote the first spool 8 resets, the first spool 8 operates in the first cavity 6, fluid output 4 is arranged on the right side of the first spool 8 in the first cavity 6 and while being positioned at free state, guarantees after the first spool 8 motions, fluid inlet 3 and fluid output 4 to be communicated with, interior second spool 10 that arranges of the second cavity 7, the second spool 10 operates in the second cavity 7, second spool 10 one end are interference fitted in the fluid inlet place of valve body, second spool 10 the other ends through the first spool and with the first spool 8 interference fit, the stressed meeting compression of the second spring 11, the second spools 10 the second spring 11 is set between the second spool 10 and the first spool 8, and pressure continues to increase, the second spool 10 can drive the first spool 8 actions, and then communication of fluid import 3 and fluid output 4, on the second spool 10, be provided with 7 type damping hole 12, the 7 12 communication of fluid imports 3 of type damping hole and the second cavitys 7, on the first spool 8, be provided with conical damping hole 13, conical damping hole 13 is communicated with the second cavity 7 and the first cavity 6, the left bore open of conical damping hole 13 is greater than right bore open, conical damping hole 13 both sides form pressure reduction △ p, the pressure direction of this pressure reduction △ p left, this pressure reduction △ p produces certain pressure left to the second spool 10 and changes with the pressure P of fluid inlet 3, the second spool 10 is with the pressure P of fluid inlet 3 to the right during single-way moving, pressure reduction △ p plays the buffering to the second spool 10, in order to avoid the pressure P force value of fluid inlet 3 is fierce, damage the second spool 10 while changing.
During use, fluid enters valve body from fluid inlet, in the situation that pressure is less than the power of the first spring and the second spring, segment fluid flow enters 7 type damping hole and conical damping holes, because aperture, conical damping hole left and right is different, can produce certain pressure reduction △ p, the pressure direction of this pressure reduction left, this pressure reduction produces certain pressure left to the second spool and changes with the pressure P of fluid inlet, the second spool is with the pressure P of fluid inlet to the right during single-way moving, pressure reduction △ p plays the buffering to the second spool, in order to avoid the pressure P force value of fluid inlet is fierce, damage the second spool while changing.Pressure reduction △ p acts on valve body, plays certain buffer function when the first spool moves.The pressure P of fluid inlet increases, and overcomes the elastic force of the second spring, and the second spool moves right; The pressure P of fluid inlet continues to increase the elastic force that overcomes the second spring and the first spring, and the second spool and the first spool move right, and move to certain position, valve standard-sized sheet, pipeline conducting; After the pressure P value of fluid inlet reduces, under the second spring and the first spring action, the first valve core reset; When the pressure P value of fluid inlet continues to reduce, the second valve core reset, one-way valve is replied original state.
