As improvement, described solenoid valve comprises newel cylindraceous, is located at the outer electromagnetic coil of newel and is located at the interior spool of newel, the two ends of newel are installed with upper seal support and bottom sealing socket, form the through hole that is tightly connected with described runner on this bottom sealing socket, described filter screen is arranged on the runner that bottom sealing socket and barrier film top links to each other.
As improvement, form a through hole on the described upper seal support and be communicated with weep hole.
As improvement, the two ends of described spool are provided with sealing gasket and lower seal pad, respectively with upper seal support and bottom sealing socket fitted seal.
At last, described solenoid valve is by being threaded on the valve gap, and seals with the O RunddichtringO; The spool of electromagnetic valve is arranged in the pipeline top, is provided with spring between spool and the bottom sealing socket, is convenient to production and assembly.
Compared with prior art, advantage of the present utility model is: be provided with filter screen above barrier film with in the runner that solenoid valve is connected, can avoid dirt or impurity particle to enter epicoele blocks runner and causes that closing of solenoid valve is malfunctioning, thereby influence the use of valve, the utility model is simple in structure, reasonable in design, can be widely used in each water system field, be particularly useful for sewage conduct.
Description of drawings
Fig. 1 is a sectional view of the present utility model.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in the figure, a kind of guide electromagnetic valve, comprise main valve 1 and the solenoid valve 2 of fixedlying connected with main valve, wherein main valve 1 comprises valve body 12, main valve plug, the valve rod 16 that has import 11, valve body 12 comprises valve gap 121 and valve seat 122, and valve gap 121 is involutory with valve seat 122, clamps septum assembly 13, valve body 12 inner cavities are divided into epicoele 15 and cavity of resorption 10, barrier film 131 in the middle of septum assembly 13 comprises and punch holder 132, die holder 133; Be supported with Returnning spring 14 between septum assembly 13 and the valve gap 121; The outer handwheel 17 of the upper end of valve rod 16 and valve body is connected, and valve rod 16 and valve gap 121 are for being threaded, and handwheel 17 and valve rod 16 pass through nut 18 to be fixed.Being provided with through hole in the described epicoele 15 is communicated with guide's cavity of solenoid valve 2.Described solenoid valve 2 comprises newel 21 cylindraceous, be located at the outer electromagnetic coil 23 of newel 21 and be located at spool 22 in the newel 21, the two ends of newel 21 are installed with upper seal support 25 and bottom sealing socket 26, upper seal support 25 is fixed on the upper end of newel 21 by nut 20, forms a through hole on the upper seal support 25 and is communicated with weep hole 29; Form through hole on the bottom sealing socket 26 and pass valve gap 121, barrier film 131, valve seat 122 and form the runner 30 that is connected with cavity of resorption 10, so just form being communicated with of epicoele 15 and import 11, and in the runner 30 above bottom sealing socket 26 and the barrier film 131, be provided with filter screen 24.The spool 22 of solenoid valve 2 is exactly an armature, is provided with spring 27 between spool 22 and the bottom sealing socket 26; Be provided with sealing gasket and lower seal pad at the two ends of spool 22, carry out fitted seal with upper seal support 25 and bottom sealing socket 26 respectively; Solenoid valve 2 is by being threaded on the valve gap 121, and is fixed with bottom sealing socket 26, is lined with seal ring.
