Technical field
The utility model relates to a kind of parts that are applied to the pneumatic mechanisms that do exercises of relevant industries equipment such as electric power, machinery, metallurgy, particularly a kind of circuit breaker pneumatic operator electromagnetism blowdown valve.
Background technology
At present, state's inner breaker pneumatic operator electromagnetism blowdown valve is divided into two kinds: a kind of is homemade electromagnetism blowdown valve, the another kind of import electromagnetically operated valve that adopts.Homemade electromagnetism blowdown valve because have that volume is big, failure rate is than problems such as height, in electric power system, progressively replaced at present by the import electromagnetically operated valve.But in the actual motion of circuit breaker air-operated loop, exist the import piston of electromagnetic valve to rupture easily, have a strong impact on the operating mechanism operate as normal, cause the equipment obstacle, even accident.The measure of handling failure is to change at present, the cost costliness.
Summary of the invention
The utility model has overcome the defective of above-mentioned existence, purpose is to influence the problem of circuit breaker pneumatic operation loop operate as normal for solving the import piston of electromagnetic valve easy fracture that is in operation, by design piston and stage clip structure, guarantee the electromagnetically operated valve precision maneuver, a kind of circuit breaker pneumatic operator electromagnetism blowdown valve is provided
The utility model circuit breaker pneumatic operator electromagnetism blowdown valve content Description:
The utility model circuit breaker pneumatic operator electromagnetism blowdown valve is characterized in that: circuit breaker pneumatic operator electromagnetism blowdown valve is made of electromagnet, piston, air chamber three parts; The electromagnet part: be made up of electromagnetic valve body, coil, armature and spring, armature is fixed on the electromagnetic valve body by spring, is provided with stage clip in armature inside and connects the conducting of seal gasket control steam vent, and the bottom is provided with steam vent; The pressure release plunger links to each other with electromagnetic valve body by spring, and seal gasket is arranged on the valve seat, and the three constitutes air chamber, and the buffering back-up ring is arranged in the air chamber between the valve seat and electromagnetic valve body, and cushion rubber bumper is arranged on the top of armature.
The seal gasket edge is groove shapes, and its air guide channel communicates with the steam vent of bottom air chamber, valve seat.
The pressure release plunger is arranged between steam vent and the top air chamber, adopts alloy aluminum to make, and the central shaft of piston adopts hollow structure.
The utility model circuit breaker pneumatic operator electromagnetism blowdown valve in circuit breaker raising pneumatic operator in service blowdown speed, has increased the air-tightness of electromagnetism blowdown part, and having reduced system's gas leakage may.Improve pneumatic operator and build pressure performance and exhaust efficiency, adaptability is strong under northern China winter low temperature running environment, increase intensity, the air-tightness of piston and improved the stability of piston action, rapid property, guarantee that pneumatic operator is built rapidly and press and pressure release, improved the security reliability of equipment.
Description of drawings
Fig. 1 is a circuit breaker pneumatic operator electromagnetism blowdown valve working state figure
Among the figure: the 1st, electromagnetic valve body, the 2nd, coil, the 3rd, armature, the 4th, air admission hole, the 5th, spring, the 6th, stage clip, the 7th, seal washer, the 8th, valve seat, the 9th, pressure release plunger, the 10th, steam vent, the 11st, buffering back-up ring, the 12nd, O-ring seal, the 13rd, buffering apron, the 14th, steam vent, the 15th, stage clip, the 16th, seal gasket, the 17th, steam vent.
Embodiment
The utility model circuit breaker pneumatic operator is achieved in that to do below in conjunction with accompanying drawing with the electromagnetism blowdown valve and specifies.See Fig. 1, circuit breaker pneumatic operator electromagnetism blowdown valve, by: electromagnetic valve body 1, coil 2, armature 3, air admission hole 4, spring 5, stage clip 6, seal washer 7, valve seat 8, pressure release plunger 9, steam vent 10, buffering back-up ring 11, O-ring seal 12, buffering apron 13, steam vent 14, stage clip 15, seal gasket 16 and steam vent 17 are formed.
Circuit breaker pneumatic operator electromagnetism blowdown valve is made of electromagnet, piston, air chamber three parts.
The electromagnet part; Be made up of electromagnetic valve body 1, coil 2, armature 3 and spring 5, armature 3 is fixed on the electromagnetic valve body 1 by spring 5, is provided with stage clip 15 in armature 3 inside and connects 17 conductings of seal gasket 16 control steam vents, and the bottom is provided with steam vent 14.
Pressure release plunger 9 links to each other with electromagnetic valve body 1 by spring 6, seal gasket 7 is arranged on the valve seat 8, the three constitutes air chamber, buffering back-up ring 11 is arranged in the air chamber between the valve seat 8 and electromagnetic valve body 1, cushion rubber bumper 13 is at the top of armature 3, the impulsive force when the two is used for 9 actions of compensator or trimmer pressure release plunger.
Seal gasket 7 edges adopt groove design, the air-tightness when increasing the solenoid closure state, and its air guide channel communicates with the steam vent 4 of bottom air chamber, valve seat 8.
8 of electromagnetic valve body 11 and valve seats guarantee the junction sealing property with O-ring seal 12 sealings.
The utility model circuit breaker pneumatic operator electromagnetism blowdown valve: electromagnet is subjected to electricity, and armature rises, and the seal gasket at armature top is blocked the exhaust passage on electromagnet top.When gases at high pressure enter the bottom air chamber, pass the air guide channel on the air chamber piston, depended on pressure official post electromagnet upper discharge hole is blocked.Gases at high pressure enter air chamber by the air guide channel on the piston, are subjected to the momentum effect of air-flow, and the plug edge on the piston closely contacts with air chamber wall.In air chamber, piston abuts against on the valve seat because of the pressure differential effect, and the realization air chamber is closed.Electromagnet outage, armature discharges steam vent, and piston action makes the pressure of air loop reach the outside atmosphere voltage levels rapidly, builds to press next time for operating mechanism and prepares.
Because the utility model has increased intensity, air-tightness and has improved the stability of piston action, rapid property, guarantee that pneumatic operator is built rapidly to press and pressure release, improved the security reliability of equipment.
