Abstract
This invention relates to electromagnetic stop valve and three-position four-way electromagnetic valve including four stop valves mounted on the valve block in two groups, magnet powder sources at the same side in parallel, each stop valve is composed of press spring, valve core. Sealing pad, guide sleeve, sealing loop, nut and combined sealing pad, in which, the valve core has a through hole with 0.1mm-0.5 mm diameter, the magnet has a back cavity opposite to the core the through hole connect the front and back cavities, the front cavities of stop valve and stop valve commonly connect to port A the middle of stop valve connects to and stop valve to c, middle cavities of stop valve sand stop valve to B and the middle of stop valve connects with the front of stop valve, the middle of stop valve with the front of stop valve.
Description
Technical field
The present invention relates to a kind of electromagnet cut off valve and three-position four-way valve, belong to the fluid operating system class.
Background technique
Existing three position four-way electromagnetic valve all adopts the guiding valve form, the defective of revealing in existing inevitably, and fluid pressure difference, the power of electromagnet also otherwise with.
Technology contents
The purpose of this invention is to provide a kind of electromagnet cut off valve and three-position four-way valve that utilizes equilibrium principle, reveal to stop internal valve, the mode that realizes above-mentioned purpose is to open a through hole in the valve core axis with electromagnet cut off valve, be communicated with ante-chamber and back cavity, four integrated being installed in of electromagnet cut off valve are promptly formed three-position four-way valve on the valve body.Its beneficial effect is that it utilizes equilibrium principle, only need less action force to open and close, same valve can be used for the fluid of different pressure, adopts soft fluorine sealing gasket, can reduce corresponding machining accuracy, there is not interior leakage problem fully, increase the service life, and the restriction that is not stressed, gas, hydraulic control system be applicable to, the present invention proves practicable through claimant's repetition test.
Description of drawings
Accompanying drawing 1 of the present invention is the structural representation of three-position four-way valve, and Fig. 2 is the section sectional view of Fig. 1, is numbered stage clip 1 among the figure, spool 2, sealing gasket 3, guide pin bushing 4, seal ring 5, nut 6, combination seal pad 7, electromagnet 8, stop valve 9,11,14,15, back cavity 10, lumen 12, ante-chamber 13, valve body 16, import A, outlet B, two-port C, the D of connection gas, fluid cylinder, the structural representation of single electromagnet cut off valve does not provide in addition.
Mode of execution
Embodiments of the invention are as follows, below in conjunction with description of drawings it, electromagnet cut off valve of the present invention is by stage clip 1, spool 2, sealing gasket 3, guide pin bushing 4, seal ring 5, nut 6, combination seal pad 7 is formed, and spool 2 has the boss of a band tapering, and electromagnet faces spool 2 places back cavity 10, be installed in four electromagnet cut off valve 9,11,14,15 of electromagnet 8 controls on the valve body 17, divide two groups and be installed on the valve body 17, upper and lower power supply parallel connection on the valve body, open and close simultaneously with electromagnet on one side; On the spool 2 through hole is arranged, through hole is communicated with ante-chamber 13 and back cavity 10; Make the fluid pressure balance that acts on the spool 2, through-hole aperture on the spool is about 0.1mm-0.5mm, be about 0.1mm as gas, liquid is about 0.5mm, the ante-chamber 13 common A mouths of the ante-chamber of stop valve 15 and stop valve 9, and the lumen of stop valve 15 leads to the D mouth, the lumen 12 logical C mouths of stop valve 9, the common B mouth of the lumen of the lumen of stop valve 14 and stop valve 11, the lumen of stop valve 15 communicates with the ante-chamber of stop valve 11, and the lumen 12 of stop valve 9 communicates with the ante-chamber of stop valve 14.Its working method is electromagnet energising on one side, then another side is in off-position, switch on, open simultaneously as the stop valve 15 and the electromagnet of stop valve 9, fluid enters from the A mouth, enter an end of clutch release slave cylinder through stop valve 9 ante-chambers 13, lumen 12, C mouth, and the backflow of the clutch release slave cylinder the other end enters from the D mouth then, through stop valve 9 lumens 12, the ante-chamber 13 of stop valve 11, lumen 12, B mouth are discharged; Vice versa.
