Detailed description of the invention
Below in conjunction with the accompanying drawings structural principle of the present utility model and embodiment are specifically described:
Filling machine three-way magnetic valve as shown in Figure 1, is provided with 3 inlet channels on valve body 1, logical
Road A, passage B and channel C, the upper and lower chamber within valve body 1 is each provided with 1 valve port, valve port A and
Valve port B, as it is shown on figure 3, passage A connect with passage B by valve port A, channel C pass through valve port B and
Passage A connects.As shown in Figure 4, the company in the upper and lower chamber of valve body 1 is realized by through hole A and through hole B
Logical.Sleeve pipe 12 is fixed and is connected with attaching nut 10 and static iron core 16 by welding respectively, forms thimble assembly.
Dynamic iron core 13 is installed on inside thimble assembly, is embedded with valve port pad 7, by being arranged on bottom dynamic iron core 13
Primary seal spring 8 in attaching nut 10, makes valve port pad 7 be sealed in valve port A.Opening as shown in Figure 5
The connecting rod closing valve body 6 passes the through hole A in valve body and through hole B, and top contacts with dynamic iron core 13,
The effect of the bottom back-moving spring 4 by being arranged in base nut 3, base nut 3 is threaded connection
Fix with valve body 1.The bottom of switch valve valve body 6, embeds and is equipped with switch valve gasket seal 5, due to main close
The force value of envelope spring 8 is much larger than back-moving spring 4, and switch valve valve body 6, under the effect of primary seal spring 8, makes
Obtaining switch valve gasket seal 5 and leave valve port B, keeping valve port B is normally open.
When coil block 17 in dead electricity, pilot gas is when passage B enters, and valve port A is due to valve
The sealing function of mouth pad 7 is closed, and pilot gas cannot be introduced into the epicoele of valve body 1.Work as coil
When assembly 17 obtains electric, dynamic iron core 13, under the effect of electromagnetic attraction, up moves, and drives valve port pad 7
Leave valve port A so that passage A connects with passage B, meanwhile, under the effect of back-moving spring 4, switch
Valve body 6 moves upward, and drives switch valve gasket seal 5 to move upward, until valve port B is sealed, and will
Passage A and channel C isolation.Now, pilot gas enters passage A by through hole B and through hole C,
Realize the pilot control to executors such as ball valves.When coil 17 dead electricity again, at the work of primary seal spring 8
Under with, valve port pad 7 seals valve port A, is pressed for 6 times by switch valve valve body simultaneously, drives switch valve sealing gasket
Sheet departs from valve port B, and the pilot gas at passage A carries out pressure release by channel C, completes opening of pilot gas
Close control.
