Description
Technical field
Dual-valve body electromagnet core pipe valve of the invention belongs to valve field, is in the core pipe stem nut series of my original invention
Dual-valve body core pipe valve plate block control valve in subfamily, be related to opening and closing, adjusting, decompression, non-return, emergency cut-off etc..
Background technique
Currently, direct-acting electromagnetic valve uses the shut-off valve vertically opened and closed substantially, guide electromagnetic valve is excessively complicated, due to existing
Valvular design feature, solenoid valve leave several sorry:
1, the degree of regulation of solenoid valve product is limited, and solenoid valve usually only switchs two states, and spool can be only in two
A extreme position cannot continuously adjust；
2, solenoid valve is limited using medium, such as temperature, viscosity of medium etc.；
3, solenoid valve is more demanding for the cleannes of environment, for that cannot be well adapted to containing granular medium,
Therefore it needs to add filter screen；
4, normally closed solenoid valve when needing to open, continues to power, can just keep it turning on shape after starting solenoid valve according to the time
State；Normally open solenoid valve when needing to close, continues to power, is just able to maintain normally off after starting solenoid valve according to the time；
5, community can not be constituted with valves such as decompression, non-return, emergency cut-offs；
6, it not can enter high-pressure medium, use in hyperbaric environment.
Summary of the invention
The object of the present invention is to provide dual-valve body electromagnet core pipe valves, overcome the shortcomings of existing solenoid valve, not only meet normal
Rule production needs, moreover it is possible to meet aerospace, nuclear energy, poisonous and harmful medium, inflammable and explosive medium, extreme environment, high-end devices
It is needed with the production needs of pipe network, security needs, energy conservation.
Dual-valve body electromagnet core pipe valve is mainly technically characterized by: the valve core tube for being wrapped in outer valve inner cavity is connection pressure
Force container, press device, medium pipe network the coaxial sleeve through the sleeve I of valve body, body cavity and valve body of fixing piece
Pipe II；There is axial interlayer in the middle part of valve core tube, interlayer is made of the intermediate pipeline section of the valve core tube of kernel and kernel radial radiation；Interlayer
Axially adjacent both sides be respectively input section and deferent segment at least one radial recirculation hole；Around the annular spool and sleeve of interlayer
The ring-shaped valve seats of at least one sleeve throat of pipe I and sleeve II constitutes sealing pair；The difference of the outer diameter of input section and deferent segment >=
0, input section and sleeve I and deferent segment are that shaft hole mode cooperates the setting of its at least one engaging portion to seal with sleeve II；Outer valve
The electromagnet that the setting of at least one direction of axial ends moves axially valve body；Under the action of both direction potential energy, valve body phase
The mobile realization opening and closing of axial reciprocating, power and energy are made in outer body cavity for valve core tube.
The annular inner wall of at least one sleeve of the sealing ring around interlayer and sleeve I and sleeve II matches composition
Secondary sealing pair.
Setting compression bullet between at least one end face of the sleeve I and sleeve II and corresponding outer valve inner face
Spring.
The effect of the compressed spring is:
One, annular spool and adjacent sleeve throat ring-shaped valve seats are closed；
Two, annular spool is left with adjacent sleeve throat ring-shaped valve seats.
Several balls are set between the annular outer wall of the valve body and the annular inner wall of outer valve.
The outer valve internal ring wall has a counterbore of a radial direction, in counterbore from the inside to the outside successively axial setting compressed spring and
Ball, the external annulus of valve body on same profile line there are two with the matched semicircle pit of ball, it is mobile in valve body axial reciprocating
When, ball respectively falls in the two pits, is respectively positioned in the state of being turned on or off.
The electromagnet is axially set in outer valve outer end, and plug one passes through outer valve end and inner cavity and sleeve I
It is connected at least one sleeve end of sleeve II.
The electromagnet shaft is to being arranged in outer valve inner face and at least one sleeve end face of sleeve I and sleeve II is attracting
It is affixed.
At least one sleeve end face of the sleeve I and sleeve II is installed by iron block.
It is described that permanent magnetic is set at least one sleeve corresponding outer valve axial inner ends face of sleeve I and sleeve II
Iron.
The interlayer is made of the intermediate pipeline section of the valve core tube of kernel and kernel radial radiation, can be it is integrated, can also
To be that kernel is axially forced to two of valve core tube parts and is constituted；Two axial end faces of the interlayer kernel are ligulate triangle slopes
Conveyance capacity is improved from interflow is diverted in face to greatest extent, realizes that medium flow direction is steady, flow resistance is small, low pressure loss；In interlayer
Two axial end faces of core can be spherical surface, is also possible to arc lower guide surface, can also be plane, concave surface and the conical surface.
At least one sleeve of the sleeve I and sleeve has a liner of tubular, and tubular liner is located at sleeve throat just and ring
Shape valve seat is integrally formed.
In conclusion dual-valve body electromagnet core pipe valve of the present invention has the active effect that
1, structure is simple, convenient for manufacture；
2, without external leakage；
3, ring-shaped valve seats and annular spool are axial straight contacts, few to rub, and sealing effect is good；
4, long service life, cost performance are high；
5, it adapts to from miniature to the various bores of ultra-large type；
6, various operating conditions are adapted to substantially；
7, the medium flow direction of pipe network is consistent with the structure of valve flowing channel design flow direction, and flow resistance is small；
8, opening and closing resistance is small；
Even if operability can be still good 9, in the state of high pressure or negative pressure；
10, energy consumption is reduced；
11, production efficiency is improved；
