Description
Technical field
Subzero valve technical equipment field is the utility model is related to, more particularly to a kind of electromagnetism sequencing valve.
Background technology
The pneumatic pilot line that Conventional cryogenic quick action emergency valve uses is opened and closed to realize the switch of pipeline.This type is special
Low temperature quick action emergency valve be applied to cryogenic tank, tank car and tank car on cut off circulation medium, particularly break down when can and
When cut off medium, be widely used in LNG, LN2, LO2, liquid ethylene and other cryogenic medias.Needed during the valve use
Use compressed air, then there will be compressed air line, have the risk that pipeline will have failure, and can also increase
Corresponding production cost.During the use of valve, if pipeline leaks, valve can not normal switch, controlling
Platform can not accurate judgement failure cause, it is difficult to is quickly found out leak point, it is necessary to which leakage point, which will be investigated, can just find out.
Replace pneumatic emergency stop valve to greatly reduce the generation of failure using sequencing valve, it is not necessary to compressed air it is whole
Set system.
Utility model content
For the needs of above-mentioned Cryo Equipment conveying, technical purpose of the present utility model is to provide a kind of relatively reliable
Electromagnetism sequencing valve.
The utility model is achieved through the following technical solutions：
Electromagnetism sequencing valve of the present utility model, including：Band magnet valve bar and magnet coil, the magnet coil are sheathed on band magnetic
One end of valve rod, control moving up and down with magnet valve bar.
Electromagnetism sequencing valve of the present utility model, the magnet coil are located at the top of valve stem sleeve, and the valve stem sleeve is sheathed on
Outside with magnet valve bar, the bottom of valve stem sleeve is on bonnet or valve body.
Electromagnetism sequencing valve of the present utility model, sealing drum, the sealing drum are provided between the valve stem sleeve and magnet coil
Top be provided with support, the support is fixedly mounted with magnet coil, sealing drum and with being provided with sealing device between magnet valve bar.
Electromagnetism sequencing valve of the present utility model, the magnet coil are explosion-proof electromagnetic coil.
Electromagnetism sequencing valve of the present utility model, the outside with magnet valve bar are provided with valve position feedback switch provided with cooperation.
Electromagnetism sequencing valve of the present utility model, the outside of the sealing drum are provided with radiation disk.
Electromagnetism sequencing valve of the present utility model, the sealing device are sylphon seal.
The beneficial effects of the utility model are:
1st, by the way that existing low temperature quick action emergency valve pneumatic control is set into Electromagnetic Control, the number of parts can be reduced
Amount, source of the gas and pipeline equipment in air control unit are particularly reduced, so as to increase the reliability of electromagnetism sequencing valve, and energy
Enough it is easy to remote control, can directly shows the on off state of valve at switch board by valve position feedback switch, realize valve
Remote control and monitoring, and other programs are chain realizes Automated condtrol；
2nd, by provided with radiation disk can reduce environment temperature around explosion-proof electromagnetic coil, so as to anti-explosion electric
Magnetic coil carries out radial-type heat dissipating, enables to the temperature of explosion-proof electromagnetic coil to be in normal temperature, and increase magnet coil uses the longevity
Life and stability.
Brief description of the drawings
Fig. 1 is the structural representation of this electromagnetism sequencing valve.
Marked in figure：1 be valve body, 2 be band magnet valve bar, 3 be sealing device, 4 be valve position feedback switch, 5 be magnet coil,
6 it is sealing drum, 7 be valve stem sleeve, 8 be radiation disk, 9 is support.
Embodiment
The utility model is described in detail below in conjunction with the accompanying drawings.
Electromagnetism sequencing valve as shown in Figure 1, including：Band magnet valve bar 2 and magnet coil 5, the magnet coil 5 are sheathed on band

In in valve body 1, and valve element is installed.Come the opening and closing of control valve by way of this Electromagnetic Control, relative to existing skill
The pneumatic control of art is relatively reliable, and easily finds trouble point, and can facilitate remote monitoring.
The magnet coil 5 is located at the top of valve stem sleeve 7, and the valve stem sleeve 7 is sheathed on the outside with magnet valve bar 2, valve rod
On bonnet or valve body 1, what it is due to conveying is ultralow temperature medium for the bottom of set 7, therefore valve stem sleeve 7 is long valve stem sleeve, valve rod
The length of set 7 can be 3~6 times of the external diameter of valve body 1.
It is provided with sealing drum 6 between the valve stem sleeve 7 and magnet coil 5, sealing drum 6 and with being provided with sealing between magnet valve bar 2
Device 3.
The top of the sealing drum 6 is provided with support 9, and the support 9 is fixedly mounted with magnet coil 5.The magnet coil 5
For explosion-proof electromagnetic coil, increase the security of property medium inflammable and explosive to transporting low temperature.
The outside with magnet valve bar 2 is provided with valve position feedback switch 4 provided with cooperation, can be straight by valve position feedback switch housing
It is connected on the open and-shut mode that distal end knows valve.The outside of the sealing drum 6 is provided with radiation disk 8,.The sealing device 3 is ripple
The seal of tube, the reliability of sealing can be increased by sylphon seal, reduce the resistance of opening and closing valve seal.
Embodiment of the present utility model is the foregoing is only, not thereby limits the scope of the claims of the present utility model, it is every
The equivalent structure or equivalent flow conversion made using the utility model specification and accompanying drawing content, or be directly or indirectly used in
Other related technical areas, similarly it is included in scope of patent protection of the present utility model.
