Further scheme as the utility model：A disc spring is provided between piston and valve deck.
Further scheme as the utility model：The dynamic iron core top is provided with protecting against shock pad.
Further scheme as the utility model：Guide rod is provided among piston.
Further scheme as the utility model：Guide rod is inserted into the guide rod being arranged in valve inner piston following position directly
In slot.
The utility model has the advantage of：When work, fluid is entered by fluid inlet, and two calutrons press operative scenario
It is powered or power-off, when energization, dynamic iron core moves up, and pilot hole is opened, and pressure reduces above piston, and piston is pushed open by fluid, flows
Body passes through；When power-off, dynamic iron core moves down under the action of the spring, blocks pilot hole, and the pressure above piston becomes larger, will be under piston
Pressure, the access of block fluid flow.When Fluid pressure is excessive, has exceeded the pressure release threshold values of relief valve, spool is pushed by fluid, fluid
It is flowed out from the outlet of relief valve, ensures the safety of valve body, when pressure is gradually reduced, spool is slowly depressed by valve core spring, until
Fluid pressure drops in safe range, and spool blocks the outlet of relief valve again.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model protected against explosion two-bit triplet solenoid valve.
Specific implementation mode
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.
As shown in Figure 1, the utility model provides a kind of protected against explosion two-bit triplet solenoid valve, including valve head 1 and calutron
2.The valve head 1 includes valve body 11, piston 12, valve deck 13, pilot hole 14 and relief valve 15, and the calutron 2 includes dynamic iron
Core 21, static iron core 22 and electromagnetic coil 23.
The static iron core 22 is tubular, is internally provided with dynamic iron core 21, and 21 top of the dynamic iron core is provided with protecting against shock pad,
21 lower part of dynamic iron core carries spring, and the spring is against in the protrusion of 22 bosom of static iron core, when spring is not by load, moves
The protecting against shock pad on the top of iron core 21 cannot touch the roof inside static iron core 22；It is tied with electromagnetic coil outside the static iron core 22
23, when electromagnetic coil is powered, static iron core 22 generates magnetic force, dynamic iron core 21 is inhaled upwards, spring-compressed, dynamic iron core 21 are upward at this time
It is mobile.
The valve body 11 is T-shape, and the foot of T-shape is fluid inlet, and the head both sides of T-shape are two fluid outlets；
Position in valve body 11 close to two exits is each provided with a piston 12, and guide rod is provided among piston 12, and guide rod is inserted into
It is arranged in the stem guiding trough of 11 internal piston of valve body, 12 following position directly；Valve body 11 is divided into an inner cavity and two by the piston 12
A exocoel, inner cavity are connected to fluid inlet, and exocoel is connected to fluid outlet；The top of the piston 12 is provided with valve deck 13, piston 12 with
It is provided with a disc spring between valve deck 13, pilot hole 14 is provided in valve deck 13 and extends in valve body 11, with the inner cavity
It is connected；The valve body 11 is bolted with valve deck 13.
The static iron core 22 is connected by screw thread with valve deck, and the bottom end of dynamic iron core 21 can block the elder generation on valve deck 13 at this time
At this moment guide hole 14, the spring in dynamic iron core 21 are in compressive state, avoid the open-top dynamic iron core of fluid 21, it is notable that this
When 21 top of dynamic iron core 22 inner top wall of protecting against shock pad and static iron core between still have gap.
The centre position of the valve body 11 is provided with a relief valve, and the relief valve includes spool and valve core spring, this is let out
The pressure release threshold values of pressure valve can be adjusted by changing the length of valve core spring.
When work, fluid is entered by fluid inlet, and two calutrons are powered or are powered off by operative scenario, when energization,
Dynamic iron core 21 moves up, and pilot hole 14 is opened, and 12 top pressure of piston reduces, and piston 12 is pushed open by fluid, and fluid passes through；Power-off
When, dynamic iron core 21 moves down under the action of the spring, blocks pilot hole 14, and the pressure of 12 top of piston becomes larger, piston 2 is pushed,
The access of block fluid flow.When Fluid pressure is excessive, has exceeded the pressure release threshold values of relief valve 15, spool is pushed by fluid, fluid
It is flowed out from the outlet of relief valve 15, ensures the safety of valve body, when pressure is gradually reduced, spool is slowly depressed by valve core spring, directly
It is dropped in safe range to Fluid pressure, spool blocks the outlet of relief valve 15 again.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Any modification, equivalent replacement or improvement etc., should be included in the utility model made by within the spirit and principle of utility model
Protection domain within.
