Abstract
This utility model discloses a kind of check valve, including valve body, spheroid and Magnet；Spheroid is mounted in valve body, and both sides are provided with end cap, and spheroid can be arranged on one end of valve body in free movement in valve body, Magnet.Spheroid is adsorbed at one end by magnetic field, is contacted with the inner surface of end cap, and the end cap inner surface is the conical surface, is fitted close with spherome surface, plays a part of to block hole at this.When fluid is entered from magnet end is installed, pressure is more than magnetic field force, promotes spheroid to enter valve body, realizes unidirectional connection.This utility model replaces mechanical force with magnetic field force, and the multiple amount of parts in unidirectional valve chamber are reduced to one, has reached the purpose for reducing amount of parts in cavity.While with non-maintaining, being not easily blocked, convection cell, gas degree of purity require to reduce, and simple structure, reliability are high, and low cost, the pressure loss are little, the advantages of heating less.
Description
Technical field
The invention belongs to field of fluid control, particularly fluid one way flow control field.
Background technology
Check valve plays a part of to control fluid flow direction, and one end allows flow of fluid, the other end to prevent flow of fluid, extensively
It is general to be applied to the field such as hydraulic pressure, pneumatic, lubrication.The inside of check valve generally by spring, spring support, alignment pin, sealing ring and
The parts such as plug are constituted.As parts are numerous, when used in unclean environment, blocking is easily produced, lose its unidirectional control
The effect of system.Fatiguability when spring is worked for a long time under high pressure, easily snaps off, and causes to lose unidirectionally controlled effect.Spring
Frame complex structure, and typically have straight flange, cause the pressure loss larger, while bringing heating problem.Sealing ring in frequently extruding and
When applying in unclean environment, aging, deformation, breakage are susceptible to, its sealing function are lost, is caused to lose its unidirectionally controlled work
With.Need time-based maintenance and inspection when in use, when these work are carried out, it is necessary to maintenance shut-downs, cause equipment Downtime and
Manpower is wasted.When check valve loses single effect, investigation is difficult, and needs experienced professional to process.
The content of the invention
To solve numerous amount of parts in the unidirectional valve chamber that prior art is present, easy blocking, needing asking for maintaining
Topic, the invention provides a Novel check valve, the valve replaces mechanical force with magnetic field force, by multiple zero in unidirectional valve chamber
Number of packages amount is reduced to one, has reached the purpose for reducing amount of parts in cavity, while being not easily blocked, non-maintaining maintenance.
A kind of check valve, including valve body, spheroid and Magnet composition；Valve body, access cover, spheroid and outlet cap；Valve body is hollow,
Spheroid is placed in valve body；Spheroid has magnetic；The inner surface setting of access cover has the conical surface for contacting with spheroid, coordinating；Access cover
With magnetic；Valve body one end is connected with access cover, and the other end is connected with outlet cap.
The access cover has annular groove, and Magnet is provided with annular groove.
The outlet of the outlet cap is rectangle, and rectangle is less than sphere diameter more than sphere diameter, another side.
The valve body is provided with sealing ring with access cover, outlet cap junction.
The present invention is had the advantages that compared to prior art：
1) amount of parts in valve body is few, multiple is reduced to one by common.
2) it is not easily blocked, the smooth spheroid of inside cavity only one of which does not have spring, the obstacles of straightsided shape structure.
3) non-maintaining, only one of which spheroid in valve body does not have rapid wear and needs the structure safeguarded.
4) simple structure, valve inner amount of parts are reduced to one.
5) reliability is high, affects without mechanical failure, seal failure.
6) low cost, the parts of cancellation have saved cost.
7) pressure loss is little, and rounder and more smooth in cavity, no straight flange, the pressure loss are little.
8) generate heat few, the little then heat of the pressure loss produces few.
9) magnet with do not contacted by control medium, it is to avoid there is possible chemical reaction.
Description of the drawings
Fig. 1 is the schematic diagram of the present invention, including such as lower component：
1. access cover；2. cannular boss；3. import；4. mouth sealing ring is entered；5. Magnet；6. valve body；7. spheroid；
8. exit seal circle；9. outlet cap.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
A kind of access cover 1 of check valve of this utility model connects for inside and outside portion；Cannular boss 2 avoids magnet and quilt
Control medium contact；Import 3 is fluid, gas access；Inlet seal circle 4 is used for inlet seal；Magnet 5 is in valve body
Spheroid applies magnetic force；The valve body of valve body 6 is hollow, and two ends are provided with hole；Spheroid 7 is, with ferromagnetism, to be controlled by magnetic field of magnets power, is risen
Unidirectional switching effect；Exit seal circle 8 is used for exit seal；The inside and outside portion's connection of 9 use of outlet cap；Outlet 10 is fluid, gas
Body is exported.Access cover 1 has annular groove, and Magnet 5 is provided with annular groove；The cannular boss 2 of access cover 1, its inner surface
It is provided with the conical surface for contacting with spheroid 7, coordinating；6 one end of valve body is connected with access cover 1, and the other end is connected with outlet cap 9.Outlet
The outlet of lid 9 is rectangle, and rectangle is less than sphere diameter more than 7 diameter of spheroid, another side.Valve body 6 and access cover 1
Junction is provided with into mouth sealing ring 4；9 junction of outlet cap is provided with exit seal circle 8.
7 magnetic field force induced impact of spheroid, absorption are provided with one end of Magnet 5 in valve body 6, block the hole opened at this.When there is stream
When body or gas never install one end of Magnet into valve body, stopped by spheroid, it is impossible to by the valve body.When from being provided with magnetic
When one end of ferrum 5 enters valve body 6, the pressure of fluid or gas overcomes magnetic field force, and spheroid 7 is pushed open, into valve body 6, never
Flow out valve body in the one end for installing Magnet.Play unidirectional connection, the effect for reversely preventing.
