At valve body, coil 90 is then loaded onto, middle liner plate 92 and shell 91 are finally mounted on the outside of the valve body with coil 90 with shape
In groups at complete bistable electromagnetic valve.
In Fig. 2 and preferred embodiment shown in Fig. 3, feed liquor access 51 and communication paths 52 are in three-port structure, and into
Liquid access 51 is arranged perpendicular to communication paths 52.Certainly, feed liquor access 51 and communication paths 52 can with arranged in a crossed manner, that is,
The angle of the two is not equal to 90 degree.At this point, the difficulty of processing of access may be will increase, it is unfavorable for manufacturing.
Preferably, feed liquor access 51 is linear, bending shape, waveform etc..
Preferably, communication paths 52 are linear, bending shape, waveform etc..Whether feed liquor access 51 or connection are logical
It road 52, can be effective when feed liquor access 51 and communication paths 52 are linear as long as the two can guarantee that liquid is connected
The difficulty of processing for reducing valve seat 50 in parallel, effectively improves the processing efficiency of product.
In order to avoid liquid leakage, first sleeve component 40 and/or the second sheath assembly 60 weld with valve seat 50 in parallel and connect
It connects.Since the liquid in the first cavity 41 and the second cavity 61 is easy in first sleeve component 40 and/or the second sheath assembly 60
It leaks with the junction of valve seat 50 in parallel, thus needs to guarantee first sleeve component 40 and the second sheath assembly 60 and valve seat in parallel
50 connection sealings avoid the generation of leakage accident, so as to effectively improve the use reliability of bistable electromagnetic valve, extend
Its service life.
Similarly, first sleeve component 40 and the welding of the first valve seat 30, and/or the second sheath assembly 60 and the second valve seat 70
Welding.
Preferably, one end for protruding into has a first boss structure 54 in the first cavity 41 of direction of valve seat 50 in parallel, and first
