Background

The two-position five-way electromagnetic valve is the most common control valve for controlling the action of the double-acting cylinder, wherein the two-position electromagnetic valve has two working states of normal state (not electrified) and action state (electrified), the five-way electromagnetic valve has five ventilation interfaces 1-5, wherein 1 is an air inlet, 2 and 4 are working ports, and 3 and 5 are air outlets. The electromagnetic valve is connected with the cylinder, the port 1 is connected with an air inlet source, the

ports

2 and 4 are connected with two air inlets of the cylinder, and the

ports

3 and 5 are connected with the muffler. If the solenoid valve is in a normal (non-energized) operating state, the cylinder is in a retracted state, and after the solenoid valve is switched to an active (energized) operating state, the cylinder will be switched to an extended state. If the corresponding state relation is to be changed, the air cylinder stretches out when the electromagnetic valve is in a (non-energized) working state, and the air cylinder retracts when the electromagnetic valve is in an energized working state, the two air inlets of the air cylinder are required to be in the opposite positions with the two air pipes of the electromagnetic

valve working ports

2 and 4.

Referring to fig. 1-4, the embodiment comprises a gas circuit board body 2, a long reversing stud 1, a central valve core 3 and a short reversing stud 4.

The air circuit board body 2 is a shell with a cavity arranged inside, and threaded holes penetrating through the cavity are respectively arranged on two sides of the air circuit board body 2, and the sizes of the two threaded holes are the same.

The long reversing stud 1 and the short reversing stud 4 have the same screw thread length, the long reversing stud 1 is also provided with a section of extension rod 11, and the short reversing stud 4 has no extension rod part. The long reversing studs 1 and the short reversing studs 4 can be in threaded connection with threaded holes on two sides of the gas circuit board body 2, namely, the positions of the long reversing studs 1 and the short reversing studs 4 can be mutually exchanged.

The central valve core 3 is in a round rod shape, and the central valve core 3 is movably positioned in the cavity of the gas circuit board body 2. When the long reversing studs 1 and the short reversing studs 4 are in threaded connection with threaded holes on two sides of the gas circuit board body 2, the long reversing studs 1 and the short reversing studs 4 respectively abut against two ends of the central valve core 3.

Four circles of outwards-protruding sealing ring grooves 31 are formed in the outer surface of the central valve core 3, and sealing rings 32 are arranged in the sealing ring grooves 31. The sealing ring groove 31 and the sealing ring 32 are tightly attached to the inner wall of the gas circuit board body 2, the cavity of the gas circuit board body 2 is divided into a first sealing space A, a second sealing space B and a third sealing space C, and an air passage 5 which penetrates through the first sealing space A and the third sealing space C is arranged in the central valve core 3.

The shell of the air circuit board body 2 is provided with a first air hole 21, a second air hole 22, a third air hole 23 and a fourth air hole 24. When the long reversing stud 1 is positioned in the threaded hole at one end of the first sealing space A and the short reversing stud 4 is positioned in the threaded hole at one end of the third sealing space C, the first air hole 21 is communicated with the third air hole 23 through the first sealing space A, and the second air hole 22 is communicated with the fourth air hole 24 through the second sealing space B. When the short reversing stud 4 is positioned in the threaded hole at one end of the first sealing space A and the long reversing stud 1 is positioned in the threaded hole at one end of the third sealing space C, the first air hole 21 is communicated with the fourth air hole 24 through the second sealing space B, and the second air hole 22 is communicated with the third air hole 23 through the third sealing space C, the air passage 5 and the first sealing space A.
