The model utility content
The purpose of this utility model is in order to overcome deficiency of the prior art, to provide a kind of simple in structure, and volume compares less, the commutation easy switching, and energy consumption is little, the heavy caliber two-bit triplet reversing solenoid valve that cost of production is relatively low.
In order to achieve the above object, the utility model adopts following scheme:
A kind of heavy caliber two-bit triplet reversing solenoid valve, comprise electromagnet and valve body, in valve body, be provided with a valve pocket, on valve body, be respectively equipped with the import that can be communicated with valve pocket, upper outlet and outlet down, described import, valve pocket and upper outlet are formed upper channel, described import, lower channel is formed in valve pocket and following outlet, in described valve pocket, be provided with the movable spool that can switch upper channel and lower channel, in import, be provided with first control channel that is connected with the valve pocket of spool upper end, in valve body, be provided with second control channel that is connected with upper outlet, described first control channel is connected with second control channel by connecting port, and connecting port is provided with the electromagnet that can open and close connecting port;
Aforesaid a kind of heavy caliber two-bit triplet reversing solenoid valve, wherein said movable spool comprises a core bar, is respectively equipped with upper piston and lower piston at the core bar two ends;
Aforesaid a kind of heavy caliber two-bit triplet reversing solenoid valve, wherein said lower piston lower end valve pocket is communicated with following outlet;
Aforesaid a kind of heavy caliber two-bit triplet reversing solenoid valve, wherein said electromagnet is arranged on the valve body top, and described electromagnet comprises a mobilizable iron core, is provided with the diaphragm seal that can seal described connecting port on iron core;
Aforesaid a kind of heavy caliber two-bit triplet reversing solenoid valve, wherein said upper piston is threaded on the core bar, and described lower piston is threaded on the core bar.
In sum, the utility model with respect to its beneficial effect of prior art is: adopt the opening and closing of a magnet control connecting port to realize that first control channel is by being connected with second control channel in the utility model, thereby make valve inner produce pressure difference, the spool of valve inner is realized the commutation switching of upper channel and lower channel in the process kind of described variation in pressure, it is simple to operate, only use an electromagnet in the utility model, reduce the volume and the loss that has reduced electric energy of valve body, saved cost of production.
Description of drawings
Generalized section of the present utility model when Fig. 1 closes for electromagnet;
Generalized section of the present utility model when Fig. 2 opens for electromagnet.
Embodiment
Below in conjunction with description of drawings and embodiment the utility model is further described:
A kind of heavy caliber two-bit triplet reversing solenoid valve, comprise electromagnet 1 and valve body 2, in valve body 2, be provided with a valve pocket 3, on valve body 2, be respectively equipped with the import 4 that can be communicated with valve pocket 3, upper outlet 5 and outlet 6 down, described import 4, valve pocket 3 and upper outlet 5 are formed upper channel, described import 4, lower channels are formed in valve pocket 3 and following outlet 6, in described valve pocket 3, be provided with the movable spool 7 that can switch upper channel and lower channel, in import 4, be provided with first control channel 8 that is connected with spool 7 upper end valve pockets 3 upper ends, in valve body 2, be provided with second control channel 9 that is connected with upper outlet 5, described first control channel 8 is connected with second control channel 9 by connecting port 89, and connecting port 89 is provided with the electromagnet 1 that can open and close connecting port 89.
Movable spool 7 described in the utility model comprises a core bar 71, is respectively equipped with upper piston 72 and lower piston 73 at core bar 71 two ends; Described upper piston 72 is threaded on the core bar 71, and described lower piston 73 is threaded on the core bar 71.
Electromagnet 1 described in the utility model is arranged on valve body 2 tops, and described electromagnet 1 comprises a mobilizable iron core 10, is provided with the diaphragm seal 11 that can seal described connecting port 89 on iron core 10.
Working principle of the present utility model:
Adopt general electromagnet 1 at valve body 2 with top in the utility model, valve body 2 is provided with an import, two outlets, import is connected with the valve pocket that is located at valve inner, the charging medium is divided into up and down through valve pocket after import enters, and two passages flow out, two outlets are sealed by two pistons respectively, establish first control channel in inlet, the charging medium enters the valve pocket top at upper piston place by first control channel, adopt the rubber sealing element sealing between upper piston and the valve body, upper piston and lower piston connect into an integral body with a core bar, the pressure area on upper piston top is greater than the pressure area below it, and upper piston is lived in outlet in the action of pressure lower seal.Work as coil electricity, when moving on the iron core, as shown in Figure 2, the pressure on the valve pocket top at upper piston place is released, and whole like this spool moves on just under action of pressure, and upper outlet is opened, following port closing, after upper outlet was opened, the upper and lower surface of upper piston had the area of pressure basic identical.But the pressure below the valve pocket is higher than top pressure, thereby forms the thrust that upper piston is made progress, and this burst thrust is greater than the downward thrust of lower piston, thereby the maintenance upper outlet is opened the state of following port closing.During coil blackout, the pressure balance at upper piston two ends, the spool integral part just moves down under the downward thrust of lower piston, gets back to original state.
