Abstract
The utility model relates to an anti-high temperature corrosion diaphragm electromagnetic valve, which comprises a valve body, a valve base, a rod-shaped armature, an armature guiding pipe and a separating film on the valve base. The periphery of the armature guiding pipe is sheathed with a plastic sealing electromagnetic wire parcel which is connected with an electric source wire. The separating film matched with the valve base made of polytetrafluoroethylene is in an umbrella shape. The center of the umbrella-shaped separating film is thin and the edge is thick. The contact part of the middle part of the separating film and a valve opening is in a convex shape, and a concave part on the back surface is connected with the rod-shaped armature. The core part on the other end of the rod-shaped armature is provided with a spring hole and a spring is positioned in the spring hole. The valve has low cost, high temperature resistance and the corrosion resistance of strong acid and alkali and partial toxic gases. The utility model can be widely used for various analyzing detection devices of fluid-state media.
Description
The utility model relates to a kind of solenoid valve.
In detection facility, the sewage that corrosivity is very strong, gas and acidity, alkalies are known from experience corrosion internal electrical magnet valve, and existing solenoid valve sealability can not be satisfied the demand, non-refractory and corrosion, cost costliness.
The purpose of this utility model provides the low high-temperature corrosion resistance diaphragm electromagnetic valve of a kind of cost, make high temperature resistant, corrosion-resistant, sealing effect is better.
The purpose of this utility model is achieved in that this valve comprises the barrier film on valve body, valve seat, shaft-like armature, armature conduit and the valve seat, armature conduit periphery is with plastic packaging electromagnetic wire bag, plastic packaging electromagnetic wire bag is connected with power line, it is characterized in that: the barrier film that cooperates with the teflon valve seat is umbrella, the umbrella diaphragm center is thin, the edge is thick, its middle part is convex with the valve port contacting point, the reverse side recess shaft-like armature interior with being contained in the armature conduit is connected, shaft-like armature the other end core has spring eye, and spring is positioned at spring eye.
Above-mentioned umbrella diaphragm center position is the taper projection, and the edge of barrier film is semi-round ring shape.
The above-mentioned shaft-like armature end that is connected with barrier film embeds in the barrier film recess, is the dop shape.
Above-mentioned shaft-like armature end also can be threaded with the barrier film recess.
Above-mentioned barrier film is to make of polytetrafluoroethylmaterial material.
Working principle of the present utility model: behind power connection, electromagnetic wire packet generation magnetic force overcomes the elastic force of spring, and armature is mentioned, and armature lower end related umbrella teflon barrier film is upwards opened, and imports and exports conducting; When cutting off the electricity supply, the magnetic force that the electromagnetic wire bag is produced disappears, and armature resets under the effect of spring together with barrier film, and center hole is shut, and import and export separate.
Advantage of the present utility model: valve seat and barrier film all adopt the high-quality teflon to make, high temperature resistant, anti-strong acid, highly basic and the corrosion of part toxic gas.Diaphragm edge partly is a semi-annular shape, conduit with it is compressed after valve seat is threaded, thereby make valve chamber space and external isolation, avoided the corrosion of medium to conduit, armature.Can be widely used in the analyzing and testing equipment of various liquid state, gaseous medium.
Below in conjunction with drawings and Examples the utility model is described in detail:
Fig. 1 is the utility model embodiment one a structural representation.
Embodiment one: high-temperature corrosion resistance diaphragm electromagnetic valve such as Fig. 1, comprise the barrier film on valve body, valve seat, shaft-like armature, armature conduit and the valve seat, armature conduit periphery is with plastic packaging electromagnetic wire bag 2, plastic packaging electromagnetic wire bag is connected with power line 8, the barrier film 5 that cooperates with teflon valve seat 7 is umbrella, the umbrella barrier film is made of polytetrafluoroethylmaterial material, and the center is thin, the edge is thick, and its edge is semi-round ring shape.Diaphragm center position and valve port contacting point are the conical protrusions shape, and shaft-like armature end embeds in the barrier film recess, connects with the dop shape.Shaft-like armature 4 the other end cores have spring eye, and spring 6 is positioned at spring eye.Housing screw 1 is fixed on conduit 3 ends, and the conduit upset is threaded with valve seat 7.
