The intrinsic safety electromagnet adopts a design of mechanical and electrical combination, greatly improves the thrust and the travel, is advanced in design, has a compact structure, and is safe, stable and reliable, convenient to install and use, and ideal.
Description
Technical field
[0001] the present invention relates to a kind of valve intrinsic safety electromagnet, belong to underground coal mine electrical equipment design and the technical field of making.
Background technology
The automatic control of colliery downhole equipment is mostly finished by electromagnetically operated valve, the critical component of electromagnetically operated valve is exactly electromagnet, down-hole electromagnet commonly used is intrinsic safety type and flame-proof type, the intrinsic safety type electromagnet is less than flameproof electromagnet drive current, caloric value is low, wiring is simple, compact conformation, especially power operation not, greatly facilitate maintenance of underground, increased fail safe; But general intrinsic safety electromagnet thrust is little, and stroke is short, requires the aperture of valve little, causes contamination resistance poor, and poor reliability has hindered the application of intrinsic safety electromagnet.
