Description
The utility model relates to a kind of solenoid valve, particularly relates to a kind of four way solenoid valve.
The path conversion is a modal method in the control.Will realize conversion and control between the multichannel at present, need to adopt a plurality of single channel solenoid valves, or several several three-way electromagnetic valves could be realized cost height, complex structure, switching difficulty.Do not see at present the solenoid valve that switches a plurality of flow directions by single solenoid valve.
The purpose of this utility model provides a kind of easy switching multichannel electromagnetic valve with regard to being at above-mentioned prior art present situation.
The purpose of this utility model is achieved in that
A kind of solenoid valve, valve body 20 and four connection mouths 9,10,22,26 that hollow cavity is arranged, closely be installed on the piston 25 in the above-mentioned hollow cavity, piston 25 is made up of piston seat 24, piston ring 12 and spring 21,24 liang of inboards of piston seat connect piston ring 12 separately, middle by spring 21 supports, piston seat 24 tops link to each other with moving unshakable in one's determination 6 of electromagnetic controller 1, electromagnetic controller 1 is made up of shell 3, coil 5, fixed core 2, moving unshakable in one's determination 6, be wound with coil 5 on the fixed core 2, the lower end connects spring 4, and electromagnetic controller 1 is connected by nut 7 with valve body 20.
Aforesaid solenoid valve, its valve body 20 lower ends are connected to hand-control device, the handle 15 of hand-control device is connected on the push rod 16, push rod 16 tops connect jacking block 13, jacking block 13 embeds in the piston seat bottom 24, spring 14 is fixed between handle 15 and the nut 19, and nut 19 is connected in the screw thread mode with valve body lower end, has outside thread 17 to cooperate with the internal thread 18 of the nut 19 of valve body 20 lower ends on the push rod 16.
Aforesaid solenoid valve is better sealing, also is connected with seal ring 8 on moving unshakable in one's determination 6, and seal ring 11 is arranged on piston ring 12.
Because the utility model adopts such structure, can make the port of solenoid valve itself constitute two kinds of loop states by electric control or manual control.In solenoid valve when energising,, coil 5 produces magnetic fields, attracts moving unshakable in one's determination 6 to move up, and moves up thereby drive piston, closely contact with valve body 20 upper ends to piston, this moment connection mouth 22,9 be communicated with, connection mouth 26,10 connections; When solenoid valve cut off the power supply, coil can not produce magnetic field, and moving unshakable in one's determination 6 effects at spring 4 move down, and moved downward thereby drive piston, closely contacted with valve body 20 lower ends to piston, and this moment, connection mouth 22,10 was communicated with and connection mouth 26,9 connections.During outage, available manual mode realizes the variation of above-mentioned path.Therefore the utlity model has simple in structurely, cost is low, can realize the advantage that a plurality of paths are changed.
Description of drawings.

Fig. 2 is the utility model embodiment 1 an A-A sectional view;
Fig. 3 is the utility model embodiment 2 a structural representation;
Fig. 4 is the utility model embodiment 2 an A-A sectional view;
Fig. 5 is the utility model embodiment 2 a lateral plan.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Embodiment 1: a kind of electromagnetic valve, valve body 20 and four connection mouths 9 that hollow cavity is arranged, 10,22,26, be installed on the piston 25 in the above-mentioned hollow cavity abreast, piston 25 is by piston seat 24, piston ring 12 and spring 21 are formed, 24 liang of inboard piston rings 12 that connect of piston seat, middle by spring 21 supports, connect seal ring 11 on the piston ring 12, piston base 24 tops link to each other with moving unshakable in one's determination 6 of electromagnetic controller 1, electromagnetic controller 1 is by shell 3, coil 5, fixed core 2, moving unshakable in one's determination 6 form, be wound with coil 5 on the fixed core 2, the lower end connects spring 4, on the moving iron core 6 seal ring 8 is arranged; Electromagnetic controller 1 is connected by nut 7 with valve body 20, and wire connecting hole 23 is arranged on the shell 3.Therefore, the utility model becomes two kinds of loop states.In solenoid valve when energising,, coil 5 produces magnetic fields, attracts moving unshakable in one's determination 6 to move up, and moves up thereby drive piston 25, closely contact with valve body 20 upper ends to piston 25, this moment connection mouth 22,9 be communicated with, connection mouth 26,10 connections; When solenoid valve cut off the power supply, coil 5 can not produce magnetic field, and moving unshakable in one's determination 12 move down under the active force of spring 4, moved downward thereby promote piston 25, closely contacted with valve body 20 lower ends to piston 25, and this moment, connection mouth 22,10 was communicated with and connection mouth 26,9 connections.Therefore by the power on/off of solenoid valve, the Placement of connection mouth is changed in these two kinds of modes, thereby realizes the conversion of path.
Embodiment 2: a kind of electromagnetic valve, the main body of its solenoid valve is identical with embodiment 1, valve body 20 lower ends are connected with manual operating device, the handle 15 of manual operating device is connected on the push rod 16, push rod 16 tops connect conical jacking block 13, and jacking block 13 embeds in the piston base 24, and spring 14 is fixed between handle 15 and the nut 19, nut 19 is connected in the screw thread mode with valve body 20 lower ends, has outside thread 17 to cooperate with the internal thread 18 of the nut 19 of valve body 20 lower ends on the push rod 16.
During power failure, the solenoid valve motor drive mechanism is inoperative, uses manual mechanism this moment.Driving handle 15, jacking block 13 move up and promote piston 25 and move up, and closely contact with valve body 20 upper ends to piston 25, handle with sleeve 15, push rod 16 also rotates thereupon, and the outside thread 17 on the push rod 16 is harmonious fixed handle 15 with the internal thread 18 on the attaching nut 19. Connection mouth 22,9 connections this moment, connection mouth 26,10 are communicated with; Rotatable handle 15, push rod 16 also rotate thereupon, and the outside thread 17 on the push rod 16 leaves the internal thread 18 of nut 19, this moment the handle 15 of leaving behind, move downward thereby drive piston 25, closely contact with valve body 20 lower ends to piston 25, this moment, connection mouth 22,10 was communicated with and connection mouth 26,9 connections.Therefore by the pushing to and leaving behind of handle 15, the Placement of connection mouth is changed in these two kinds of modes, thereby realizes the conversion of path.
