SUMMERY OF THE UTILITY MODEL
The utility model discloses an overcome the automatic reciprocating valve of gas accuse of conventional design all is external amortization exhaust structure (amortization exhaust choke valve) on two end covers to make whole valve structure great, and amortization exhaust structure (amortization exhaust choke valve) is hit bad by the foreign object easily in the course of the work, lead to the shortcoming that whole reciprocating valve can not normally work, the to-be-solved technical problem of the utility model is to provide a design compacter, the appearance is more pleasing to the eye, use reliable gas accuse automatic reciprocating valve.
The utility model is achieved by the following concrete technical means:
a reliable pneumatic control automatic reciprocating valve comprises a valve body, a valve rod, an end cover, a back pressure adjusting screw and a silencing exhaust structure; be equipped with mobilizable valve rod in the valve body, the end cover is installed at the valve body both ends, and the valve rod both ends cooperate with the end cover, and the end cover top is equipped with the screw chamber, and the backpressure adjusting screw is installed in the screw chamber with detachable mode, and the backpressure adjusting screw cooperatees with the valve rod, and the end cover lateral part is equipped with the exhaust chamber, is equipped with amortization exhaust structure in the exhaust chamber, exhaust chamber and screw chamber intercommunication.
Furthermore, the bottom of the valve body is provided with a P gas port, the top of the valve body is provided with a gas port A and a gas port B, and the P gas port is positioned between the gas port A and the gas port B.
Further, the silencing exhaust structure is a silencing exhaust throttle valve.
Compared with the prior art, the utility model discloses following beneficial effect has:
the utility model discloses in fall into two parts with backpressure adjusting screw and amortization exhaust structure, integrate again in the end cover contains the face outward, both satisfied the functional requirement of automatic gas accuse reciprocating valve, also prevented some defects that amortization exhaust structure caused, so, reached design compacter, the appearance is more pleasing to the eye, the reliable in use effect.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a structural schematic diagram of a pneumatic control automatic reciprocating valve of a conventional design.
The labels in the figures are: 1-valve body, 2-valve rod, 3-end cover, 4-backpressure adjusting screw, 41-screw cavity, 5-silencing exhaust structure, 51-exhaust cavity, 6-P air port, 7-A air port and 8-B air port.
Detailed Description
The invention is further described below with reference to the accompanying drawings:
examples
A reliable pneumatic control automatic reciprocating valve is shown in figure 1 and comprises a valve body 1, a valve rod 2, an end cover 3, a back pressure adjusting screw 4 and a silencing exhaust structure 5; a movable valve rod 2 is arranged in the valve body 1, end covers 3 are arranged at two ends of the valve body 1, two ends of the valve rod 2 are matched with the end covers 3, a screw cavity 41 is arranged at the top of each end cover 3, a back pressure adjusting screw 4 is detachably arranged in each screw cavity 41, the back pressure adjusting screw 4 is matched with the valve rod 2, an exhaust cavity 51 is arranged at the side part of each end cover 3, a silencing exhaust structure 5 is arranged in each exhaust cavity 51, and each exhaust cavity 51 is communicated with the corresponding screw cavity 41;
the bottom of the valve body 1 is provided with a P gas port 6, the top of the valve body 1 is provided with a gas port A7 and a gas port B8, and the P gas port 6 is positioned between the gas port A7 and the gas port B8;
the silencing exhaust structure 5 is a silencing exhaust throttle valve;
in the utility model, after the air flow enters from the P air port 6, the backpressure at two ends of the valve rod 2 is controlled by adjusting the adjusting screw, so that the axial stress of the valve rod 2 generates pressure difference, thereby pushing the valve rod 2 to move in two directions and leading the A air port 7/B air port 8 to ventilate and exhaust alternately;
fig. 2 can know, a is the valve body, b is the valve rod, c is the end cover, d is the backpressure adjusting screw, e is amortization exhaust structure, the automatic reciprocating valve of gas accuse of conventional design all is external amortization exhaust structure e (amortization exhaust choke valve) on two end covers c, thereby make whole valve structure great, and amortization exhaust structure e (amortization exhaust choke valve) is broken by the foreign object easily in the course of the work, lead to whole reciprocating valve can not normally work, in order to overcome above-mentioned prior art not enough, the utility model discloses fall into two parts with backpressure adjusting screw 4 and amortization exhaust structure 5, integrate again in 3 outer envelopes of end cover faces, both satisfied the functional requirement of automatic gas accuse reciprocating valve, also prevented some defects that amortization exhaust structure 5 caused, so, reached the design compacter, the appearance is more pleasing to the eye, reliable in use's effect.
Although the present disclosure has been described in detail with reference to the exemplary embodiments, the present disclosure is not limited thereto, and it will be apparent to those skilled in the art that various modifications and changes can be made thereto without departing from the scope of the present disclosure.
