Description
The utility model relates to a kind of explosion-proof type high-pressure solenoid valve.
Existing explosion-proof type solenoid valve adopts cylinder mode or encapsulation type structure to carry out explosion-proof and flame proof more, the solenoid valve working medium pressure is all below 2.5MPa, can not satisfy the needs of actual use far away, particularly can not satisfy the usage requirement of high-voltage explosion-proof under the deep layer mine.
The purpose of this utility model provides guide's one piston type mine explosion-proof high-pressure solenoid valve that a kind of working pressure is 4-6MPa.
The purpose of this utility model realizes with following design.
By electromagnet start-up part and valve body explosion-proof high-pressure magnet valve dimerous.An integrated type pilot valve is arranged between electromagnet start-up part and main valve body, and the main valve body valve core is a piston type.Pilot valve is positioned on the valve gap of valve body, and pilot valve core is connected with the moving iron core of electromagnetism and links with the moving iron core of electromagnetism.The pilot valve core chamber is communicated with valve body piston valve core rear chamber and valve body import by the import duct that is positioned on valve body valve gap and the valve body, and the pilot valve outlet is communicated with the valve body outlet by the outlet duct that is positioned on valve body valve gap, the valve body.Switching is controlled by pilot valve in the inlet/outlet duct, and pilot valve core, valve body piston valve core are equipped with return spring.
When mine uses with the explosion-proof high-pressure solenoid valve, insert behind the conveyance conduit that high-pressure medium enters the pilot valve core chamber by the valve body import simultaneously by the import duct and valve body spool rear chamber produces back pressure to the valve body piston valve core, spool is in closed condition under the back pressure effect.Opens solenoid valve, electromagnet coil power, electromagnetic core action, pilot valve core link thereupon, and pilot valve is opened.Medium is discharged by pilot valve outlet, outlet duct in the indoor and valve body spool rear chamber of pilot valve core, and the suffered back pressure of valve body spool is removed the valve body piston valve core and is subjected to the import high-pressure medium and pushes and move, and valve body is opened.Close solenoid valve, electromagnetic action disappears, pilot valve core is return under the return spring effect, pilot valve is closed, pilot valve core chamber and valve body spool rear chamber charge into high-pressure medium, the suffered back pressure of piston valve core raises, and last piston valve core is closed valve body in back pressure and return spring effect return.
Mine adopts threaded flame-proof type to connect with the explosion-proof interface of explosion-proof high-pressure solenoid valve electromagnet, and the jointing dress adds sealing gasket, to improve flame proof, the explosion-proof performance of solenoid valve.
Mine adopts guide's one piston cylinder operator with the explosion-proof high-pressure solenoid valve, open and close by pilot valve control valve body, valve body adopts the spool of piston cylinder operator, thereby improved the working pressure of solenoid valve in the situation that does not increase power of electromagnet, make the explosion-proof high-pressure solenoid valve be easy to miniaturization and explosion-proof, flame proof processing, reduced the manufacture cost of explosion-proof high-pressure solenoid valve simultaneously.Adopt screw thread to add sealing gasket, simplify the structure, improved explosion-proof, the explosion insulation performance of valve body valve seal, thus safe and reliable.
Accompanying drawing is a structural drawing of the present utility model, further specifies the utility model below in conjunction with accompanying drawing.
Fig. 1 is mine explosion-proof high-pressure electromagnetic valve structure figure;
Fig. 2 is the partial structurtes sectional view (enlarged view) of mine with explosion-proof high-pressure solenoid valve electromagnet one pilot valve part.
Mine explosion high-pressure solenoid valve structure as shown in the figure, (1) is screw among the figure, (2) chromium weldering, (3) anti-explosion is electromagnetic iron, (4) loam cake, (5) valve body of main valve, (6) import duct, (7) piston valve core return spring, (8) piston valve core, (9) piston cylinder, (10) outlet duct, (11) loam cake, (12) O RunddichtringO, (13) outer cover, (14) tenminal block, (15) outlet port sealing circle, (16) wire outlet screw, (17) ground terminal, (18) concentrating flux sleeve, (19) moving iron core group, (20) spring, (21) concentrating flux sleeve, (22) coil, (23) magnetic conducting plate, (24) set screw.
As shown in the figure, mine is made of electromagnet start-up part and valve body two-part with explosion-proof solenoid valve, and an integrally-built pilot valve is arranged between electromagnet start-up part and valve body, and the valve body spool is a piston valve core.Pilot valve is positioned on the valve body valve gap, the pilot valve core chamber is by being positioned at import duct and the valve body import on valve body valve body, the valve gap, valve body piston valve core rear chamber is communicated with, and the pilot valve outlet is communicated with the valve body outlet by the outlet duct that is positioned on valve body valve gap and the valve body.
Connect power supply when starting solenoid valve, electromagnetic core drives pilot valve core and mentions, the pilot valve core chamber is communicated with pilot valve with the pilot valve inlet/outlet and opens, indoor high-pressure medium of pilot valve core and valve body spool rear chamber inner high voltage are situated between by the outlet duct, the valve body outlet is discharged, the suffered high-pressure medium back pressure of valve body piston valve core disappears, and the valve body piston valve core is pushed down at inlet's high-pressure medium and risen, and valve body is opened.Cut off the electricity supply when closing solenoid valve, electromagnetism disappears, pilot valve core whereabouts return under the return spring effect is closed pilot valve, high-pressure medium enters pilot valve core chamber and valve body spool rear chamber by the import duct and is full of, make piston valve core be subjected to the back pressure effect that high-pressure medium produces again, piston valve core moves down return valve body is closed under back pressure and return spring effect.
Adopts between the electromagnet part outer casing of solenoid valve and valve body and between electromagnet part outer cover and loam cake to be threaded, jointing is adorned and is added sealing gasket, thereby has guaranteed flame proof, the explosion-proof performance of valve effectively.
