Abstract
The utility model discloses an intrinsically safe electromagnetic pilot valve used in an explosive gas environment. The intrinsically safe electromagnetic pilot valve comprises a valve body, and two two-position three-way pilot valve cores with identical structures which are arranged on the upper and lower sides of the horizontal center line in the valve body, wherein the right end part of the valve body is a concave cavity; the ejector rods of the two two-position three-way pilot valve cores horizontally extend into the concave cavity and are connected with one end of a lever, respectively; two electromagnetic actuators are hermetically arranged at the right end of the valve body in the positions corresponding to the concave cavity; push rods are horizontally and fixedly connected with the armatures of the two electromagnetic actuators respectively; the two push rods extend to be contacted with the levers respectively; a mounting box is fixedly connected onto the housing of the electromagnetic actuator; a control circuit board of the electromagnetic actuator is hermetically fixed in the mounting box through potting adhesive; and dustproof and waterproof intrinsically safe electrical connector receptacle and an electromagnetic actuator action indicator lamp are arranged on the side wall of the mounting box. The intrinsically safe electromagnetic pilot valve used in the explosive gas environment has the advantages of reducing the labor intensity of the miners and improving the mining efficiency.
Description
Technical field
The utility model relates to pilot valve, especially relates to the INTRINSICALLY SAFE TYPE ELECTRO-MAGNETIC PILOT VALVE that is used for the explosion gas environment.
Background technique
Pilot valve is widely used in fields such as mine, chemical industry, metallurgy, oil, environmental protection, is used for finishing electrical signal and transforms to the action of mechanical energy.At present, the pilot valve that uses on the hydraulic support is many by manual control.Along with the progress of science and technology, more and more higher to the working automation degree requirement of hydraulic support.How the pilot valve that uses on electromagnetic actuator and the hydraulic support being combined to realize automation control, satisfy the requirement of explosion proof in this environment that contains explosion gas under the coal mine again, is the problem that those skilled in the art study always.
Summary of the invention
The INTRINSICALLY SAFE TYPE ELECTRO-MAGNETIC PILOT VALVE that is used for the explosion gas environment that provides a kind of automaticity high just is provided the utility model purpose.
For achieving the above object, the utility model can be taked following technical proposals:
The INTRINSICALLY SAFE TYPE ELECTRO-MAGNETIC PILOT VALVE that is used for the explosion gas environment described in the utility model, it comprises valve body, is symmetricly set on the identical two-bit triplet guide spool of two structures of the upper and lower both sides of horizontal central line in the described valve body; The right part of described valve body is a curved cavity, the push rod of described two two-bit triplet guide spools extends horizontally to respectively in the described cavity and links with an end of lever, be provided with two electromagnetic actuators at the valve body right-hand member corresponding to the sealing of cavity position, level is fixed with push rod respectively on the armature of described two electromagnetic actuators, and described two push rods extend to the position that contacts with described lever respectively; Be fixed with mounting box on described electromagnetic actuator housing, by the casting glue sealing and fixing electromagnetic actuator control circuit board arranged in described mounting box, the mounting box sidewall is provided with dustproof and waterproof intrinsic safety type electrical socket and electromagnetic actuator action indicator.
The utility model advantage is to seal two electromagnetic actuators that are arranged on valve body right-hand member cavity position, to control electrical signal and be converted into magnetomotive, drive push rod by armature and press the lever that is arranged in the described cavity, according to the push rod of the described two-bit triplet guide spool of control requirement driving, the hydraulic support action is finished in the motion that reaches controlling liquid.Greatly reduce coal-getter's labor intensity, improved coal mining efficient.
