Abstract
The utility model discloses an explosion proof proportion magnet, which has the function of explosion proofing. An explosion proof structure is arranged at the outer part of a general proportion magnet. The working principle of the utility model is the same with a general proportion magnet, the electromagnetic conversion principle is adopted, and an input electrical signal is converted to an analogue mechanical output signal. The utility model can be matched with various hydraulic valves with different functions to compose various explosion proof proportion hydraulic valves, an electric input signal can be infinitely transformed to a proportion hydraulic output signal, and the functions of an explosion proof proportion pressure valve, an explosion proof proportion flow regulating valve, an explosion proof proportion directional control valve, etc. can be realized. Owing to that the utility model has the advantages of compact structure and low price, the utility model can be widely used for various hydraulic equipment needing the proportion control of occasions with explosive gases.
Description
The utility model relates to a kind of proportion electro-magnet with explosion-proof performance, is applicable to that the damp occasion need be with the hydraulic test of proportion electro-magnet.
Up to now, adopt the electromagnetic conversion principle, input electrical signal is converted to the proportion electro-magnet of the mechanical output signal of simulation, can form various ratio hydraulic valves with the hydraulic valve of various functions, but, can not be used to have the place of damp because its power of proportion electro-magnet far surpasses the requirement of coal mine explosion-proof rules.
The purpose of this utility model provides a kind of proportion electro-magnet that can be used for having the damp place.
Main points of the present utility model are: will have proportion electro-magnet now by the explosion--proof regulations requirement, at its shell and each joint zero, parts explosion suppresion surface is set, and explosion-proof wiring device is set in feed cable introducing place, and both kept the operation principle of former proportion electro-magnet, increased explosion-proof performance again.
Remarkable result of the present utility model: because of the utility model only increases explosion prevention function on former proportion electro-magnet basis, easily realize and enlarged the scope of application, can be used for the place that colliery, chemical industry etc. have imflammable gas, improved the main frame automaticity.
Be further described below in conjunction with accompanying drawing.
Fig. 1 structure cutaway view of the present utility model.
As shown in the figure, proportion electro-magnet assembly (2) is contained in the explosion-resistant enclosure (1), pole shoe (4) and explosion-resistant enclosure (1), and guide pipe (3) and explosion-resistant enclosure (1), the composition surface of terminal box (8) and explosion-resistant enclosure (1) all is provided with explosion suppresion surface (5).
Be provided with terminals (6), sealing clamp (7) in feed cable introducing place by explosion--proof regulations, in terminal box (8), be provided with binding post (9) and interior ground connection (10).
Claims (2)
1. flame-proof type proportion electro-magnet, it is characterized in that: proportion electro-magnet assembly (2) is contained in the explosion-resistant enclosure (1); Feed cable introducing place is provided with terminals (6), and sealing clamp (7) is provided with binding post (9) and interior ground connection (10) in terminal box (8).
