Problems solved by technology
[0003] However, after a long time of use of the existing electromagnetic pilot valve, the sensitivity between the pressure rod and the touch rod in the valve body will decrease, especially when the pressure rod controls the pilot valve. There is a problem of poor interception effect when stringing components, which may easily lead to liquid leakage in the closed state, which affects the use effect

The embodiment of the invention discloses a mining intrinsically safe electromagnetic pilot valve. The mining intrinsically safe electromagnetic pilot valve is characterized in that a valve body is fixedly connected to an electromagnetic driver, a socket shell is arranged on the electromagnetic driver, the mining intrinsically safe electromagnetic pilot valve further comprises an abutting device which is arranged between the valve body and the electromagnetic driver, an elastic mounting groove is formed in the middle of the upper end of the valve body shell, a mounting screw hole is formed in the center of the bottom in the elastic mounting groove, an insertion hole is formed in the center of the bottom in a driver shell, the lower end of the guide rod is screwed in the mounting screw hole, the upper end of the guide rod is inserted in the insertion hole, the guide rod is sleeved with an abutting plate and a spring, the spring is arranged between the lower end of the abutting plate and the inner bottom of the elastic mounting groove, and the upper end of the abutting plate abuts against a pressing rod. According to the mining intrinsically safe electromagnetic pilot operated valve, the abutting device is arranged between the valve body and the electromagnetic driver, the abutting device can abut against the middle of the pressing rod all the time in the using process, upward pushing force is generated, it can be guaranteed that liquid is completely intercepted, and the sensitivity and the using effect are guaranteed.
Description
technical field [0001] The embodiment of the present invention relates to the technical field of electromagnetic valves, in particular to an intrinsically safe electromagnetic pilot valve for mining. Background technique [0002] In the prior art, as a very important valve body structure, the pilot solenoid valve is widely used in fields such as coal mining and oil mining, and is especially suitable for flow control of liquid, water, hot water, gas, oil, gas, etc. Generally in use, when the power is turned on, the valve stem is lifted by the electromagnetic force, and the pilot valve port is opened. At this time, the upper cavity of the solenoid valve is relieved through the pilot hole, and a pressure difference is formed around the main valve core. When the power is off, under the action of the spring force and the gravity of the main valve core, the valve stem resets, the pilot hole is closed, the main valve core moves downward, and the main valve port opens. Close; the p...
