Description
Technical field
The utility model relates to valve field, particularly relates to a kind of multi-functional butterfly valve.
Background technique
Butterfly valve rotates by butterfly plate the object reaching open and close around valve shaft; in fluid line, main rising is cut off and throttling action; existing butterfly valve structure is simple, function singleness; in sewage delivering pipe in sewage disposal system, usually also need sampling cock is installed, inspection by sampling is carried out to the sewage of discharging; Decompression valves is installed; carry out the pressure in equalizing main, this not only adds the quantity of the element in sewage delivering pipe, but also increase difficulty and the cost of installation and maintenance.
Summary of the invention
According to above technical problem, the utility model provides a kind of multi-functional butterfly valve of integration, comprise valve body, adpting flange, butterfly plate, valve shaft, handwheel, it is characterized in that: also comprise surge drum, piston, connecting rod, handle, spring, vertical tube, horizontal pipe, discharge opeing relief tube, the two ends of described valve body are provided with adpting flange, the inside of described valve body is provided with butterfly plate, described butterfly plate is vertically provided with valve shaft, the inside of described valve shaft offers vertical tube, the upper end of described valve shaft is provided with handwheel, the upper end of described handwheel is provided with surge drum, described vertical tube is communicated with surge drum, the inside of described surge drum is provided with piston, the upper end of described piston is connected with handle by connecting rod, the outside of described connecting rod is provided with spring, described surge drum is provided with discharge opeing relief tube, the inside of described butterfly plate offers horizontal pipe, described horizontal pipe is communicated with vertical tube.
The downward-sloping setting of described discharge opeing relief tube.
The beneficial effects of the utility model are: the utility model improves on original butterfly valve, namely horizontal pipe has been offered in the inside of butterfly plate, vertical tube has been offered in the inside of valve shaft, horizontal pipe is communicated with vertical tube, also add surge drum in the upper end of handwheel, when valve opening, horizontal pipe is parallel with the flow direction of fluid, at this moment fluid flows through from horizontal pipe, undertaken sampling and pressure release by the discharge opeing relief tube on surge drum, butterfly valve is not only made to have the functions such as sampling and pressure release, and the installation of functional valve in the sewage delivering pipe decreasing in sewage disposal system, thus reduce difficulty and the installation and maintenance cost of installation and maintenance.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
According to Fig. 1, the utility model is further described:
As Fig. 1, valve body-1, adpting flange-2, butterfly plate-3, valve shaft-4, handwheel-5, surge drum-6, piston-7, connecting rod-8, handle-9, spring-10, vertical tube-11, horizontal pipe-12, discharge opeing relief tube-13.
Embodiment 1
The utility model comprises valve body 1, adpting flange 2, butterfly plate 3, valve shaft 4, handwheel 5, surge drum 6, piston 7, connecting rod 8, handle 9, spring 10, vertical tube 11, horizontal pipe 12, discharge opeing relief tube 13, adpting flange 2 is separately positioned on the two ends of valve body 1, first vertical tube 11 is offered in the inside of valve shaft 4 during installation, horizontal pipe 12 is offered in the inside of butterfly plate 3, then butterfly plate 3 is arranged on the inside of valve body 1, valve shaft 4 is vertically arranged on butterfly plate 3, horizontal pipe 12 is communicated with vertical tube 11, handwheel 5 is arranged on the upper end of valve shaft 4, again discharge opeing relief tube 13 is arranged on surge drum 6, piston 7 is arranged on the inside of surge drum 6, then spring 10 is arranged on the outside of connecting rod 8, again the upper end of piston 7 is connected with handle 9 by connecting rod 8, finally surge drum 6 is arranged on the upper end of handwheel 5, vertical tube 11 is communicated with surge drum 6.
Embodiment 2
During use, fluid enters valve body 1 from adpting flange 2, rotate handwheel 5 by hand, handwheel 5 drives valve shaft 4 to rotate, thus drive the opening and closing of the butterfly plate 3 rotary control valve body 1 be connected with valve shaft 4, when valve body 1 is opened, horizontal pipe 12 is parallel with the flow direction of fluid, at this moment fluid flows through from horizontal pipe 12, when needs sample, 9 are pulled handle with portable, piston 7 is moved up, in horizontal pipe 12, the fluid of flowing upwards flows into surge drum 6 from vertical tube 11, fluid in surge drum 6 flows out from discharge opeing relief tube 13, when the pressure in valve body 1 raises, also piston 7 can be made to move up, by the balanced action of spring 10, piston 7 is made to be in equilibrium position, when the pressure in valve body 1 continues to raise, piston 7 is made to continue to move up, make surge drum 6 and discharge opeing relief tube 13 conducting, fluid in surge drum 6 flows out from discharge opeing relief tube 13, thus carry out pressure release.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvement, these improvement also should be considered as protection domain of the present utility model.
