Description
Technical field
The present invention relates to a kind of solenoid valve market more particularly to a kind of piston electromagnetic valves.
Background technique
Solenoid valve is an executive component in automatic control system, for controlling fluid on and off, changes flow direction,
Show fluid effect etc..The high-pressure solenoid valve of the prior art does not all account for valve body and plunger tube component under high pressure, stream
The high pressure waterjet that body forms the impact of shank and fluid by position under high pressure.Often solenoid valve is in early period
Using effect can be with seal is slowly cut and causes to leak after a period of use.Secondly, solenoid valve is common under high pressure
Sealing element can not play sealing function, not be that be ejected be exactly to be cut, stability is bad, and often the service life cannot be guaranteed.In addition,
Solenoid valve can generate vortex in either on or off moment, media flow, and solenoid valve either on or off is made to be obstructed.
Summary of the invention
The present invention provides that a kind of simple structure, the operation is stable, production cost be low, the scope of application in order to solve problem above
Extensively, the piston electromagnetic valve that stress levels are high, explosion-proof effect is good.
The technical scheme is that the solenoid valve includes piston boit, electromagnetic coil, spring, piston rod, sealing
Part, gas port, warming extensible member, spool, valve body, valve seat, balance hole, piston ring, valve deck, valve bonnet seal part, the valve body
Setting is arranged on valve body in solenoid valve base, the valve seat, and the spool is arranged on valve seat, and the piston ring is set
Set in spool two sides, the balance hole setting in piston ring lower part, the warming extensible member setting spool and valve deck it
Between, the gas port is arranged in valve deck, and the sealing element is arranged at gas port and is connected with piston rod, described
Piston rod top connecting spring, the spring top are connected on piston boit, and the electromagnetic coil is arranged outside piston boit
Side.
The engaging portion of the spool and valve seat is equipped with seal spool part.
The configuration of the present invention is simple, the operation is stable, production cost are low, applied widely, stress levels are high, explosion-proof effect is good.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
1 is piston boit in figure, and 2 be electromagnetic coil, and 3 be spring, and 4 be piston rod, and 5 be sealing element, and 6 be gas port, and 7 be temperature
Feel extensible member, 8 be spool, and 9 be valve body, and 10 be valve seat, and 11 be balance hole, and 12 be piston ring, and 13 be valve deck, and 14 be valve bonnet seal
Part, 15 be seal spool part.
Specific embodiment
A kind of piston electromagnetic valve, the solenoid valve include piston boit 1, electromagnetic coil 2, spring 3, piston rod 4, sealing
Part 5, gas port 6, warming extensible member 7, spool 8, valve body 9, valve seat 10, balance hole 11, piston ring 12, valve deck 13, valve bonnet seal
Part 14, in solenoid valve base, the valve seat 10 is arranged on valve body 9 for the setting of valve body 9, and the setting of spool 8 exists
On valve seat 10, in 8 two sides of spool, the setting of balance hole 11 is described in 12 lower part of piston ring for the described setting of piston ring 12
Warming extensible member 7 be arranged between spool 8 and valve deck 13, the gas port 6 is arranged in valve deck 13, the sealing element
5 are arranged at gas port 6 and are connected with piston rod 4, the 4 top connecting spring 3 of piston rod, 3 top of spring
It is connected on piston boit 1, the setting of electromagnetic coil 2 is in 1 outside of piston boit.
The engaging portion of the spool 8 and valve seat 10 is equipped with seal spool part 15.
Above embodiments are only to illustrate the invention and not limit technical solution described in the invention；Cause
This, is although this specification has been carried out detailed description to the invention referring to above-mentioned each embodiment, this field
It is to be appreciated by one skilled in the art that still can modify to the invention or equivalent replacement；And all do not depart from this
The technical solution and its improvement of the spirit and scope of innovation and creation, should all cover the scope of the claims in the invention
In.
