Abstract

A pneumatically controlled reversing valve comprises a valve base with a sealing ring, an upper valve spool and a lower valve spool which are provided with sealing rings and installed on a valve body, and a valve stem which is capable of conducting up and down movement in the upper and lower valve spools and the valve body to match with an air inlet port, an exhaust port and a working gas port that are arranged on the valve body. A first, a second, a third, a fourth and a fifth diaphragms are sequentially connected with the valve stem, the first and the second diaphragms match with the upper valve spool, the third and the fourth diaphragms match with the lower valve spool, and the fifth diaphragm matches with the valve body. In the pneumatically controlled reversing valve, except that the O-shaped sealing rings on the valve spools and the valve base are statically sealed with the valve body, the diaphragms are installed on the valve stem and match with the upper and the lower valve spools and the valve body in a dynamic seal, so as to partition the valve cavities and improve the seal among the valve cavities, resulting in better sealing effect and more rapid reversing speed. The pneumatically controlled reversing valve has the advantages of remarkably improved reversing efficiency, and more safe and reliable service.

Description

Pneumatic reversal valve

Technical field

The utility model relates to the selector valve in a kind of Pneumatic Transmission, particularly a kind of Pneumatic reversal valve that is used to change air current flow direction or air-flow break-make direction.

Background technique

In Pneumatic Transmission, the control of automation airflow-reversing makes the working air current commutation, generally all adopt Pneumatic reversal valve, now the Pneumatic reversal valve of Shi Yonging only has the static seal between spool and valve body, valve rod upper and lower moving in spool reaches the commutation purpose, do not intercept, seal but have significantly between each part, sealing is relatively poor, inefficiency.

The Pneumatic reversal valve that patent No. CN200520034784.6 " Pneumatic reversal valve " only provides a kind of piston and spool to adopt the independent split type structure has been avoided the piston hair fastener that causes because of valve body hole and cylinder bore disalignment, the irremovable problem of spool fully.

Summary of the invention

Technical problem to be solved in the utility model is: a kind of Pneumatic reversal valve is provided, and simple in structure, compact, commutating speed is fast, good airproof performance, high working efficiency, use safer, reliable.

The technical scheme in the invention for solving the above technical problem is: Pneumatic reversal valve, valve seat by the band seal ring, the upper and lower spool of band seal ring is installed on the valve body, and valve rod upper and lower suction port, relief opening, work gas port mobile and on the valve body in upper and lower spool, valve body cooperate, also be connected with the first, second, third, fourth, the 5th diaphragm on the described valve rod in turn, first, second diaphragm cooperates with upper valve core, three, the 4th diaphragm cooperates with lower valve core, and the 5th diaphragm cooperates with valve body.

Compared with prior art, advantage of the present utility model is: this Pneumatic reversal valve has O RunddichtringO and valve seal on spool, valve seat be the static seal, diaphragm also is installed on valve rod, valve rod each diaphragm in moving process cooperates with upper and lower spool, body movable sealing, not only intercept each valve pocket but also increased sealing between each valve pocket, make commutating speed faster, sealing effect is better, and commutation efficient improves greatly.

Description of drawings

Fig. 1, structural representation of the present utility model (no pressure air control).

Fig. 2, structural representation of the present utility model (pressure air control is arranged).

Embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is further described.

On two surfaces of valve body 1 mounting hole is arranged, two relief opening R, the S of band screw arranged on the right flank, a suction port P has the two working hole A, the B that are with screw on the left surface, spool bore and screw are arranged on the end face, is shoulder hole in the middle of the lower end.

Valve rod 2 is big on the multidiameter shaft, little down, lower end blind hole mounting spring 14, and it is primary diaphragm 8, secondary diaphragm 10, tertiary membrane sheet 11, the 4th diaphragm 13, the 5th diaphragm 3 of rectangle that the cross section is installed on valve rod 2 successively.

The end face of upper valve core 7 is close to primary diaphragm 8 for the middle concave arc surface that through hole is arranged, and upper valve core 7 and valve seat 9 are separated and is sealed, and is embedded with two O RunddichtringOs 6 on the peripheral wall, two pores that correspondence is arranged on the middle annular groove, communicate.

Lower valve core 5 lower surface grooves cooperate with the 4th diaphragm 13, lower valve core 5 and valve body 1 are separated and sealed, and are embedded with O RunddichtringO 6 on the peripheral wall, and two pores that correspondence is arranged on the annular groove of lower end, communicate there is a breach 12 on the last end periphery.

Upper and lower spool 7,5 is enclosed within on the valve rod 2, and second, third diaphragm 10,11 is kept apart upper and lower spool, and spool, the valve rod that has assembled is pressed in the valve body 1.

Valve seat 9 lower ends are embedded with O RunddichtringO 6, and there is control gas port C the upper end, and valve seat 9 is screwed in the screw of valve body 1 end face.

For the requirement of processing technology also is embedded with copper pad 4 in the jointing place groove of lower valve core 5 and valve body 1.

During work, the no pressure air in control gas port C place passes through, valve rod 2 is not stressed, under the effect of spring 14, move up, the diaphragm that drives simultaneously on it moves up, at this moment the 5th diaphragm 3 leaves valve body 1, the 4th diaphragm 13 on the lower valve core 5 is to upper process, the lower end surface of being close to lower valve core seals, and tertiary membrane sheet 11 also leaves the upper-end surface of lower valve core, and at this moment secondary diaphragm 10 moves up and projection, the lower end surface of being close to upper valve core seals, primary diaphragm 8 also moves up, and projection is close to valve seat 9 lower end surfaces and seals, and at this moment pressure air enters from suction port P, enter work gas port A by pore on the lower valve core and the breach on the lower valve core 12, be that P-A communicates, the gas port B that works simultaneously communicates with relief opening S, as shown in Figure 1.

When control gas port C feeds pressure air, valve rod 2 moves down under the effect of pressure air, at first, primary diaphragm 8 moves down the last concave arc surface of being close to upper valve core, secondary diaphragm 10 disengagings contact with upper valve core, lose isolation, seal action, tertiary membrane sheet 11 is close to the upper-end surface and the sealing of lower valve core, the 4th, the 5th diaphragm 13,3 with valve body on, the sealing of downstairs hole, at this moment the pressure air that enters from suction port P enters work gas port B through pore on the lower valve core and the breach on the lower valve core 12, be that P-B communicates, the gas port A that works simultaneously communicates with relief opening R, reaches the commutation purpose and is transformed into P-B from P-A, and simultaneously B-S communicates and is transformed into A-R and communicates.
