Description
Technical field
The present invention relates to Subzero valve technical field, particularly a kind of ultralow temperature solenoid valve.
Background technique
At present, along with industrial automation process is more and more faster, more and more higher for the requirement of process automation control.At present, in the ultralow temperature pipeline of China, realize automation or semi-automatic Cryogenic valve or blank, main manifestations be LNG, liquid oxygen, liquid nitrogen, etc. the conveying of super-low liquid, for example, in cold storing and fresh-keeping technical field, when temperature is during higher than certain setting temperature, ultralow temperature solenoid valve is opened automatically, liquid nitrogen is transported in ice chest, thereby reaches the effect of cooling down.
Again for example, in the core ice chest of present domestic LNG gas station, implementation procedure control can only solve with low temperature Emergeny Cutoff Valves, all producers all can only adopt this valve, this low temperature Emergeny Cutoff Valves is emergency episode control valve, but due to the production of domestic not this valve, and inlet valve price is too high, so the research and development of ultralow temperature solenoid valve are extremely urgent, but the ability of not producing low temperature valve between the current domestic producer that can produce solenoid valve, causing domestic used low-temperature solenoid valve is now nearly all dependence on import.
Summary of the invention
The object of the invention is to overcome the shortcoming of prior art, provide that a kind of simple in structure, flow is large, sealing is tight, be applicable to open and close the ultralow temperature solenoid valve that occasion, switching motion that frequency is high are sensitive, can realize telecontrol.
Object of the present invention is achieved through the following technical solutions: a kind of ultralow temperature solenoid valve, it comprises valve body and electromagnetic coil, in described valve body, be provided with feed pathway, the through hole of liquid outlet channel and connection feed pathway and liquid outlet channel, the top of valve body is provided with pilot hole and pilot hole is communicated with liquid outlet channel, in described electromagnetic coil, be provided with blind hole, top and blind hole that electromagnetic coil is arranged on pilot hole are communicated with pilot hole, in the passage that described pilot hole and blind hole form, be provided with magnetic core, the bottom of magnetic core is provided with groove, in described groove, be provided with the tapered shape of sealing tetrafluoro and sealing tetrafluoro bottom, the tapering part of sealing tetrafluoro is pressed on the top of through hole.
The degree of depth of described blind hole is greater than pilot hole.
Described through hole, pilot hole and blind hole is all perpendicular to feed pathway setting.
Described blind hole and the diameter of pilot hole are all greater than magnetic core.
The present invention has the following advantages: in the passage that (1) pilot hole of the present invention and blind hole form, be provided with magnetic core, the bottom of magnetic core is provided with groove, in groove, be provided with the tapered shape of sealing tetrafluoro and sealing tetrafluoro bottom, the tapering part of sealing tetrafluoro is pressed on the top of through hole, in the time that electromagnetic coil is switched on, magnetic core is picked up, and sealing tetrafluoro and valve body sealing surface depart from, the circulation of cryogenic liquide; In the time of electromagnetic coil power-off, magnetic core declines rapidly, the tapering part of sealing tetrafluoro is pressed on the top of through hole firmly, thereby blocks the circulation of cryogenic liquide, therefore, only need just can control fast the circulation of cryogenic liquide or block to electromagnetic coil energising or power-off, switching motion is very sensitive, and is applicable to open and close the occasion that frequency is high, again due to sealing tetrafluoro and contacting of through hole be line and curved surface contact and seal polytetrafluoroethylsealed sealed very tight, therefore, there is the tight feature of sealing.(2) electromagnetic coil of the present invention only need be connected with wire just can complete to its energising, therefore, be easy to realize telecontrol.(3) what magnetic core of the present invention was suffered is magnetic force, and it is very large that magnetic force can do, and therefore, the present invention can be used for the occasion that flow is large.

In figure, 1-valve body, 2-electromagnetic coil, 3-feed pathway, 4-liquid outlet channel, 5-through hole, 6-pilot hole, 7-blind hole, 8-magnetic core, 9-groove, 10-seals tetrafluoro.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described, and protection scope of the present invention is not limited to the following stated:
As shown in Figure 1, a kind of ultralow temperature solenoid valve, it comprises valve body 1 and electromagnetic coil 2, in described valve body 1, be provided with the through hole 5 of feed pathway 3, liquid outlet channel 4 and connection feed pathway 3 and liquid outlet channel 4, the top of valve body 1 is provided with pilot hole 6 and pilot hole 6 is communicated with liquid outlet channel 4, in described electromagnetic coil 2, be provided with blind hole 7, top and blind hole 7 that electromagnetic coil 2 is welded on pilot hole 6 are communicated with pilot hole 6.As shown in Figure 1, in the passage that pilot hole 6 and blind hole 7 form, be provided with magnetic core 8, the bottom of magnetic core 8 is provided with groove 9, is provided with sealing tetrafluoro 10 and the sealing tetrafluoro 10 tapered shapes in bottom in described groove 9, and the tapering part of sealing tetrafluoro 10 is pressed on the top of through hole 5.As shown in Figure 1, in the time that electromagnetic coil 2 is switched on, magnetic core 8 is picked up under the effect of magnetic force, and sealing tetrafluoro and valve body sealing surface depart from, cryogenic liquide circulation; In the time of electromagnetic coil 2 power-off, magnetic core 8 declines, the tapering part of sealing tetrafluoro 10 is pressed on the top of through hole 5, block the circulation of cryogenic liquide, therefore, only need switch on or power-off just can be controlled fast the circulation of cryogenic liquide or block to electromagnetic coil 2, switching motion is very sensitive, and is applicable to open and close the occasion that frequency is high.
As shown in Figure 1, the degree of depth of blind hole 7 is greater than pilot hole 6; Through hole 5, pilot hole 6 and blind hole 7 all arrange perpendicular to feed pathway 3; The diameter of blind hole 7 and pilot hole 6 is all greater than magnetic core 8.
Working procedure of the present invention is as follows: when toward electromagnetic coil 2 interior galvanization, magnetic core 8 is picked up under the effect of magnetic force, and sealing tetrafluoro 10 departs from valve body sealing surface, and at this moment cryogenic liquide enters liquid outlet channel 4 from feed pathway 3 via through holes 5; In the time of the electric current of cutoff solenoid 2, magnetic core 8 declines, and the tapering part of sealing tetrafluoro 10 is pressed on the top of through hole, thereby has blocked the circulation of cryogenic liquide.
