Signaling switch 21 is housed on the utility model valve gap 2, spring 22 is arranged on its bar, between bar and the valve rod 3 steel ball 23 is arranged, switch cover 24 is arranged.
Valve gap 2 is threaded with flange circle 27 inner rings, and flange circle 27 is connected with the flange 25 of valve body 1 by bolt 26, and seal ring 28 is arranged in the valve body 1, and the inner chamber of block 6 cooperates with the pipe 29 of valve gap 2, and managing 29 upper ends has waterproof grommet 30.
The utility model is simple in structure, rationally, adopted flexible bellow to make seal isolation motion main part, have stroke long, high pressure resistant, be active in one's movements reliability height, advantages such as good airproof performance.Can be by multiple material such as rubber-like, stainless steel, copper material etc., it is withstand voltage poor to have solved cap shape lacquer disk(-sc), problems such as stroke weak point.
Solenoid valve adopts the cup-shaped static iron core of mountain word, with the moving little Spielpassung of iron core of T type, has increased magnetic density, has strengthened magnetic tractive force, has reduced driving voltage, electric current, has improved explosion-proof performance.
Status switch is provided with, and the fine motion signaling switch produces signal output by the open and close state of steel ball by valve rod control groove control fine motion signaling switch, and the open and close state of reaction valve is suitable for the valve distant control, observes.
Following is accompanying drawing of the present utility model.
Fig. 1 is a structural drawing of the present utility model.
Following is embodiment of the present utility model:
The connection mouth 31 of valve body 1 is a suction port, and 32 is the air outlet, and connection mouth can be made and be threaded or the flange plate connection, can be used for various gas pipelines, toxic and harmful pipeline, applicability is strong, apparent size, installation dimension is with consistent with the common stop valve of bore, and versatility is good.
Valve rod 3 has control groove 13 spacing with controlling rod 11 interlocks, the fixing block 6 in valve rod upper end, the lower end connects seal disc 5, seal disc 5 is connected flexible bellow 4 with valve gap 2, spring 7,8, electromagnetic valve component is fixed on the valve gap 2 by static iron core 17 screw threads, fastening ring 19 adjusting plays and fastening location, valve gap 2 upper end necks are established seal ring 30 and are cooperated with block 6, make waterproof sealing.
Working principle of the present utility model is as follows:
The pulling block 6 interlock valve rods 3 that make progress move upward, and valve rod control groove 13 is spacing with controlling rod 3 interlocks, and seal disc 5 interlocks make progress, and center hole is opened, spring 7,8, and bellows all is compressed, and this practicality this moment is analysed type and is in the ventilation open state.Steel ball 23 is pressed to control flume 13 by spring 22, and the fine motion signaling switch is closed, no signal output.
