Description
Technical field
The utility model relates to a kind of pneumatic valve, especially a kind of double spool pneumatic control valve.
Background technique
Pneumatic control valve is exactly take pressurized gas as power source, take cylinder as final controlling element, and go to drive valve by means of annexes such as valve positioner, transducer, solenoid valve, guarantor position valve, gas holder, pneumatic filters, realize switching value or proportion expression adjustment, to receive the control signal of industrial automation control system and complete adjutage track media, but cause due to regular use the wearing and tearing of spool very fast when traditional pneumatic control valve operates, and can not the water yield used be added up.Therefore, a kind of double spool pneumatic control valve is devised for the problems referred to above.
Model utility content
The purpose of this utility model is to provide a kind of double spool pneumatic control valve, to solve the problem proposed in above-mentioned background technology.
The purpose of this utility model is achieved by following technical proposals: a kind of double spool pneumatic control valve, comprise sealing film, spring, supporting frame, water meter, monitor unit, valve gap, air pressure entry port, valve rod, stuffing box packing, spool, valve body and valve seat, described sealing film is arranged on the two ends of valve gap; The below of described valve gap is installed with spring; Support frame as described above is arranged on the middle-end of valve body; Described valve body is provided with water meter; Described monitor is arranged in valve body; Described valve gap is arranged on the top of valve body; Described valve body upper end is provided with air pressure entry port; The below of described valve gap is fixedly connected with valve rod; The inside of described valve body is provided with stuffing box packing; The below of described valve rod is provided with spool; Described valve seat is arranged on valve body bottom.
Further, described water meter and monitor are fastenedly connected and can carry out branch's dismounting.
Further, described valve rod is provided with two semicircle shape spools.
Further, support frame as described above fixes the motion of valve rod.
Further, described valve body adopts stainless steel material to make.
Compared with prior art, the beneficial effects of the utility model are this kind of double spool pneumatic control valves, easy to use, are swift in response, safe to use, simultaneously low cost, long service life and quality is light and handy, are applicable to promoting the use of.
Accompanying drawing explanation
Fig. 1 is the utility model whole structure figure;
In figure: 1-sealing film, 2-spring, 3-supporting frame, 4-water meter, 5-monitor, 6-valve gap, 7-air pressure entry port, 8-valve rod, 9-stuffing box packing, 10-spool, 11-valve body, 12-valve seat.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment; technological scheme in the utility model embodiment is clearly and completely described; obviously; described embodiment is only the utility model part embodiment; instead of whole embodiments; based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, the utility model discloses a kind of double spool pneumatic control valve, comprise sealing film 1, spring 2, supporting frame 3, water meter 4, monitor unit 5, valve gap 6, air pressure entry port 7, valve rod 8, stuffing box packing 9, spool 10, valve body 11 and valve seat 12, described sealing film 1 is arranged on the two ends of valve gap 6; The below of described valve gap 6 is installed with spring 2; Support frame as described above 3 is arranged on the middle-end of valve body 11; Described valve body 11 is provided with water meter 4; Described monitor 5 is arranged in valve body 11; Described valve gap 6 is arranged on the top of valve body 11; Described valve body 11 upper end is provided with air pressure entry port 7; The below of described valve gap 6 is fixedly connected with valve rod 8; The inside of described valve body 11 is provided with stuffing box packing 9; The below of described valve rod 8 is provided with spool 10; Described valve seat 12 is arranged on valve body 11 bottom.
Described water meter 4 and monitor 5 are fastenedly connected and can carry out branch's dismounting, are convenient to monitor Water usage and changes facilitate; Described valve rod 8 is provided with two semicircle shape spools 10, effectively alleviates the wearing and tearing of spool 10; Support frame as described above 3 fixes the motion of valve rod 8, prevents valve rod 8 from causing because of unbalance stress bending; Described valve body 11 adopts stainless steel material to make, and improves the life-span of use, and this kind of double spool pneumatic control valve, easy to use, is swift in response, safe to use, simultaneously low cost, long service life and quality is light and handy.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any reference character in claim should be considered as the claim involved by limiting.
