Abstract
Disclosed is a pneumatic piston type sewage valve, which relates to a pneumatic sewage valve provided with a valve body, a sewage inlet and an outlet are disposed on the valve body, a straight through passageway is arranged between the inlet and the outlet, a piston cavity is disposed in the valve body and crossed with the passageway, a piston is disposed in the piston cavity, the diameter of the piston is larger than that of the passageway, a stepped spacer ring is disposed at the rear end of the piston, control ports are disposed on the piston cavity at both sides of the spacer ring, and because the straight through passageway is arranged between the inlet and the outlet, the requirements of high speed flow of sewage can be met; and because the piston cavity is disposed in the valve body and crossed with the passageway, the piston is disposed in the piston cavity, the diameter of the piston is larger than that of the passageway, the stepped spacer ring is disposed at the rear end of the piston, the control ports are disposed on the piston cavity at both sides of the spacer ring, the valve will not be easily clamped by impurities in sewage and leak, the closing speed is fast, high-speed instant passing and cutting of sewage can be achieved, the valve can be used normally at sites needing fast and frequent valve closing and opening, and is suitable for draining sewage.
Description
Technical field
The present invention relates to pneumatic sewage valve, is a kind of Pneumatic piston sewage valve specifically.
Background technique
We know, and are often straight-through between the import of existing pneumatic sewage valve and the outlet, and giving vent to anger in the side that always alters course, inner passage, can not satisfy the swiftly flowing requirement of sewage; And Pneumatic butterfly valve, ball valve etc. are because there is baffle plate the centre, valve is blocked by the impurity in the sewage easily and leaks, and this type of pneumatic valve closing velocity is slow, the high speed moment that can't realize sewage by and cut off, can't normally use in the frequent fast occasion that opens and closes of needs.
Summary of the invention
The technical problem that the present invention solves is, solve existing pneumatic sewage valve and can not satisfy the swiftly flowing requirement of sewage, valve is blocked by the impurity in the sewage easily and leaks, closing velocity is slow, the high speed moment that can't realize sewage by and cut off, the problem that can't normally use in the fast frequent occasion that opens and closes of needs, provide a kind of and can satisfy the swiftly flowing requirement of sewage, valve is not easy to be blocked by the impurity in the sewage and leaks, closing velocity is fast, the high speed moment that can realize sewage by and cut off the Pneumatic piston sewage valve that can normally use in the frequent fast occasion that opens and closes of needs.
Technological scheme of the present invention is, be provided with valve body, valve body is provided with sewage import and outlet, the main structure characteristics are, are straight-through runner between import and the outlet, and interior the intersecting with runner of valve body is provided with piston cavity, be provided with piston in the piston cavity, piston diameter is greater than Flow diameter, and piston rear end is provided with the stepped shaft spacer ring, and the piston cavity of spacer ring both sides is provided with the control mouth.
Piston of the present invention is provided with stuffing box gland.
Piston cavity of the present invention rear end is provided with end cap.
The runner for leading directly between import and the outlet the invention has the beneficial effects as follows, owing to can satisfy the swiftly flowing requirement of sewage; Because interior the intersecting with runner of valve body is provided with piston cavity, be provided with piston in the piston cavity, piston diameter is greater than Flow diameter, piston rear end is provided with the stepped shaft spacer ring, the piston cavity of spacer ring both sides is provided with control mouthful, and valve is not easy to be blocked by the impurity in the sewage and leaks, and closing velocity is fast, the high speed moment that can realize sewage by and cut off, can normally use in the frequent fast occasion that opens and closes of needs.The present invention is applicable to effluent discharge.
Description of drawings
Accompanying drawing is a kind of structural representation of the present invention, also is a kind of embodiment's schematic representation.
Embodiment
Pneumatic piston sewage valve as shown in the figure, be provided with valve body 6, valve body 6 is provided with sewage import 1 and outlet 4, import 1 and export between 4 and to be straight-through runner, valve body 6 interior intersecting with runner are provided with piston cavity 8, be provided with piston 2 in the piston cavity 8, piston 2 diameters are greater than Flow diameter, runner capable of blocking when piston 2 passes runner.Piston 2 is provided with stuffing box gland 3, can strengthen the sealing between piston 2 and runner.Piston 2 rear ends are provided with stepped shaft spacer ring 7, and the piston cavity 8 of spacer ring 7 both sides is provided with control mouth 5,9, and piston cavity 8 rear ends are provided with end cap 10, the convenient installation.As can be seen from the figure, control mouth 9 is located on the end cap.During use, sewage import 1 is connected with pipeline with outlet 4, control mouthful connects a source of the gas, and another control mouthful is communicated with atmosphere, by controlling the source of the gas air inlet and giving vent to anger the advance and retreat of control piston 2, the folding of realization valve.Because import 1 and exporting between 4 to straight-through runner can be satisfied the swiftly flowing requirement of sewage; Because valve body 6 interior intersecting with runner are provided with piston cavity 8, be provided with piston 2 in the piston cavity 8, piston 2 diameters are greater than Flow diameter, piston 2 rear ends are provided with stepped shaft spacer ring 7, the piston cavity 8 of spacer ring 7 both sides is provided with control mouthfuls 5,9, and valve is not easy to be blocked by the impurity in the sewage and leaks, and opening and closing speed is fast, the high speed moment that can realize sewage by and cut off, can normally use in the frequent fast occasion that opens and closes of needs.
