Abstract
The utility model discloses a diaphragm type pneumatic blowoff valve which relates to a pneumatic blowoff valve. The diaphragm type pneumatic blowoff valve is provided with a valve body; the lower part of the valve body is provided with a sewage inlet and a sewage outlet; a straightway runner is arranged between the sewage inlet and the sewage outlet; a packing cup is arranged in the upper part of the valve body; the packing cup divide the valve body into an upper cavity and a lower cavity; a sealing ball is arranged in the lower cavity; the sealing ball is flexibly connected with the center of the packing cup; a reset spring is arranged between the upper end of the valve body in the upper cavity and the packing cup; and a control port is arranged on the upper cavity. The diaphragm type pneumatic blowoff valve can meet the requirements of high speed floating of the sewage, is hard to be blocked by the impurities in the sewage to cause leakage, has quick on-off speed, can realize the high speed instant passing through and cutting off of the sewage, can be normally used on occasions needing quick and frequent opening and closing, and is suitable for sewage promoting.
Description
Technical field
The present invention relates to pneumatic sewage drain valve, is a kind of diaphragm type pneumatic sewage drain valve specifically.
Background technique
We know that the runner between the import of existing pneumatic sewage drain valve and the outlet is often straight-through, and inner flow passage is always crooked or the change direction, 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 diaphragm type pneumatic sewage drain 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 lower portion is provided with sewage import and outlet, and the main structure characteristics are to be straight-through runner between import and the outlet, the valve body internal upper part is provided with leather cup, leather cup is separated into upper cavity and lower chamber with valve body, is provided with ball sealer in the lower chamber, and ball sealer and leather cup central authorities flexibly connect, be provided with Returnning spring between upper cavity inner valve body upper end and the leather cup, upper cavity is provided with the control mouth.
Leather cup of the present invention middle part is provided with pad, and ball sealer and pad central authorities flexibly connect.
Ball sealer outer surface of the present invention is provided with elastic sealing layer.
Returnning spring of the present invention inboard is provided with guide sleeve.
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 the valve body internal upper part is provided with leather cup, leather cup is separated into upper cavity and lower chamber with valve body, be provided with ball sealer in the lower chamber, ball sealer and leather cup central authorities flexibly connect, valve is not easy to be blocked by the impurity in the sewage and leaks, switching 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.The present invention is applicable to that sewage promotes.
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
Diaphragm type pneumatic sewage drain valve as shown in the figure is provided with valve body 8, and valve body 8 bottoms are provided with sewage import 1 and outlet 11, import 1 and export between 11 and to be straight-through runner, valve body 8 internal upper parts are provided with leather cup 6, and leather cup 6 middle parts are provided with pad 5,7, and leather cup 6 stirs effective up and down.Leather cup 6 is separated into upper cavity and lower chamber with valve body 8, is provided with ball sealer 10 in the lower chamber, and ball sealer 10 flexibly connects with leather cup 6 central authorities, and as can be seen from the figure, ball sealer 10 flexibly connects not fragile leather cup 6 with pad 7 central authorities.Ball sealer 10 outer surfaces are provided with elastic sealing layer 9, can improve the sealing between ball sealer 10 and the outlet 11.Be provided with Returnning spring 2 between upper cavity inner valve body 8 upper ends and the leather cup 6, Returnning spring 2 inboards are provided with guide sleeve 3, can avoid Returnning spring 2 bendings, improve performance.Upper cavity is provided with control mouth 4, is used to control leather cup 6 and stirs up and down.During use, import 1 is connected with sewage conduct, outlet 11 is connected with vacuum line, control mouthfuls 4 is communicated with vacuum line and atmosphere respectively through three-way valve, when the control three-way valve makes control mouthfuls 4 be communicated with atmosphere, leather cup 6 is upset downwards under the action of gravity of the thrust of Returnning spring 2 and ball sealer 10, and ball sealer 10 is adjacent to outlet 11 under the suction of outlet 11, and blowdown valve cuts out; When the control three-way valve made control mouthfuls 4 be communicated with vacuum line, leather cup 6 overcomes the gravity of ball sealer 10 and outlet 11 under the effect of the pulling force of Returnning spring 2 and upper and lower chamber pressure difference suction made progress and overturns, and with ball sealer 10 pull-ups, blowdown valve is opened.Because import 1 and exporting between 11 to straight-through runner can be satisfied the swiftly flowing requirement of sewage; Because valve body 8 internal upper parts are provided with leather cup 6, leather cup 6 is separated into upper cavity and lower chamber with valve body 8, be provided with ball sealer 10 in the lower chamber, ball sealer 10 flexibly connects with leather cup central authorities, rely on ball sealer 10 to be adjacent to outlet 11 and close blowdown valve, valve is not easy to be blocked by the impurity in the sewage and leaks, and the blowdown valve 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.
