Unless otherwise defined, technical and scientific term all used in this specification is led with technology of the invention is belonged to
The normally understood meaning of the technical staff in domain is identical.Used term is only in the description of the invention in this specification
The purpose of description specific embodiment is not intended to the limitation present invention.Term "and/or" used in this specification includes one
Any and all combinations of a or multiple relevant listed items.
- Fig. 3 refering to fig. 1, the check valve of the embodiment of the present invention include first shell 10, second shell 20, ball 30, ball
Seat 40, compressed spring 50 and spring base 60, first shell 10 and second shell 20 seal against each other fixation, are formed in the valve of check valve
Chamber, ball 30, ball base 40 and compressed spring 50 are contained in valve insertion；Ball 30 is undertaken in ball base 40, ball base 40
It is equipped with the concave arc curved surface to fit with the circular arc camber of ball 30, one end of compressed spring 50 is connected to ball base 40, separately
One end is connected to spring base 60, and spring base 60 is fixed in the mounting hole of first shell 10.
Wherein, first shell 10 is equipped with medium flow channel 11, and second shell 20 is equipped with medium flow pass 21, is situated between
Matter flow channel 11, medium flow pass 21 are connected to valve insertion respectively, center line and the medium outflow of medium flow channel 11
Not on the same line, the axis direction of medium flow channel 11 and the side outer rim 30 of ball are tangent for the center line in channel 21.
Valve insertion includes the cylindrical cavity in the first shell 10 and the semicircle inner cavity in second shell 20,
Medium flow channel 11 extends into cylindrical cavity, and ball base 40 and compressed spring 50 are contained in cylindrical cavity, and with
Medium flow channel 11 is staggered；The spherical shape of ball 30 matches with the semicircle inner cavity in second shell 20, in intraluminal fluid
When body pressure is lower than setting value, ball 30 is under the thrust of compressed spring 50, the circular arc camber and second shell of ball 30
Semicircle inner cavity on 20 is mutually adjacent to, closed dielectric flow pass 21.
When the liquid with certain speed injects valve insertion by medium flow channel 11, fluid is formed in valve insertion
Vortex, since the axis direction and ball 30 of medium flow channel 11 are tangent, under the action of fluid tangential force, ball 30 occurs
Rotation, with being gradually increased for valve insertion Fluid pressure, ball 30 can overcome the resistance of compressed spring 50 and be detached from second shell
Semicircle inner cavity on 20, liquid are flowed out by medium flow pass 21.
The material of ball 30 can be ceramics, the form of the glass perhaps ball such as stainless steel 30 can be solid or empty
The heart.
It is understood that the decrement of compressed spring 50 depends on spring base in the case where compressed spring 50 determines
The distance between 60 and ball base 40, the present embodiment can be adjusted because spring 50 and medium flow channel 11 are arranged in a staggered manner from outside
Position of the spring base 60 in first shell 10 protrudes into the length of valve insertion to change spring base 60, to adjust liquid discharge
The cracking pressure of mouth, without removing check valve from pipeline.
In the case where changing spring base 60 and protruding into the length of valve insertion and be also unable to satisfy regulatory demand, can also first by
Spring base 60 takes out out of first shell 10, replaces compressed spring 50, changes the rigidity of compressed spring 50.
In one embodiment, the lateral surface of spring base 60 is equipped with external screw thread, is equipped in the mounting hole of first shell 10 interior
Screw thread (not shown), spring base 60 are screwed with first shell 10 and connect.For example, when needing to increase opening for liquid outlet
When opening pressure, spring base 60 can be made to be further threaded into first shell 10.
Optionally, the bottom of spring base 60, which is equipped with, puts forth effort hole 61, for example, putting forth effort hole 61 can be six prismatic, crosswise etc., incites somebody to action
Tool insertion puts forth effort that relaxedly and rapidly spring base 60 can be threaded in or out in first shell 10 in hole 61.
In the above-described embodiment, first shell 10 is in the edge of cylindrical cavity and second shell 20 in semicircle
The edge of shape inner cavity is equipped with Flange-shaped Parts flange, and Flange-shaped Parts flange is equipped with several location holes, utilizes the screw threads such as screw, bolt
Fastener, which sequentially passes through each location hole, to seal against each other fixation for first shell 10 and second shell 20.
Preferably scheme, on the Flange-shaped Parts flange of first shell 10 and/or the Flange-shaped Parts flange of second shell 20 is set
There is annular groove 12, annular groove 12 is for accommodating O-ring seal, by the way that first shell 10 and second is arranged in O-ring seal
Between shell 20, enhance the sealing performance between first shell 10 and second shell 20.
In the above-described embodiment, it can also be not provided with ball base 40, and directly by ball 30 and the one of compressed spring 50
End connection.
It should be noted that specification of the invention and its a better embodiment of the invention is given in the attached drawing, still,
The present invention can be realized by many different forms, however it is not limited to this specification described embodiment, these embodiments
Not as the additional limitation to the content of present invention, purpose of providing these embodiments is makes understanding to the disclosure
It is more thorough and comprehensive.Also, above-mentioned each technical characteristic continues to be combined with each other, and forms the various embodiments not being enumerated above,
It is considered as the range of description of the invention record；It further, for those of ordinary skills, can be according to the above description
It is improved or converted, and all these modifications and variations should all belong to the protection domain of appended claims of the present invention.
