Description
Technical field
The utility model relates to the valve of water-in and water-out control in the current pipe network, especially a kind of rubber seal valve.
Background technique
At present; Old-fashioned rubber seal valve; Its rubber gasket is the sealing surface that rotates and compress or leave valve body along with the rotation of handle, and because of there is spin friction in the sealing surface of rubber gasket when the valve open and close and valve body, so rubber gasket very easily damages and occurs leaking.In order to address this problem; A kind of rubber seal valve also occurred on the market now, the rubber gasket of this valve is connected on the bottom plane of a guide pin bushing, and guide pin bushing relies on valve gap spacing and realize can only moving axially and can not rotating; Guide pin bushing and valve rod are for being threaded; Drive guide pin bushing, rubber gasket realization axial motion through rotatablely moving of valve rod, under the rotatablely moving of handle, just can realize the open and close of valve like this; Rubber gasket does not just rotatablely move in the process of open and close simultaneously, and its serviceability has improved greatly; But the valve gap of this kind valve is to be connected through the internal thread of its outside thread with the top of the endoporus of valve body; The internal thread that requirement rotation knockout is arranged in the endoporus of valve body in other words; Because valve body structure is complicated; Its part profile is not symmetrical with the axis of screw thread, and realizing rotating its injection moulding of screw thread or die casting mould so in the above will be very complicated, improve die cost greatly; The screw thread fuse was taken out in manual rotation after this structure adopted the demoulding, though can reduce die cost, but increased labor intensity greatly, also be inconvenient to the automation of producing; So just be difficult to promote.
Summary of the invention
Be not durable in order to overcome existing rubber seal valve, the shortcoming that difficulty of processing is big, the utility model provides a kind of rubber seal valve, and this rubber seal valve mechanism is simple, durable, easy processing, cost are low, easy to use, reliable.
The utility model solves the technological scheme that its technical problem adopted: this rubber seal valve comprises valve body and from bottom to top is arranged at rubber gasket, guide pin bushing, valve rod, the valve gap in the endoporus of valve body; And the handle that is connected in the valve rod top; The O RunddichtringO is housed on valve rod; At the endoporus of valve body and the joint of valve gap rubber seal is arranged, valve gap is to be connected through the outside thread of its internal thread with the top of the endoporus of valve body.The rubber gasket of this rubber seal valve is connected on the bottom plane of guide pin bushing; Guide pin bushing relies on valve gap spacing and realize can only moving axially and can not rotating, and guide pin bushing and valve rod are for being threaded, through the drive guide pin bushing that rotatablely moves, the rubber gasket realization axial motion of valve rod; Like this under the rotatablely moving of handle; Just can realize the open and close of valve, rubber gasket does not just rotatablely move in the process of open and close simultaneously, and its serviceability has improved greatly.Because the valve gap of this rubber seal valve is to be connected through the outside thread of its internal thread with the top of the endoporus of valve body, in other words with the internal thread conversion on the top of traditional valve body for outside thread, outside thread is very easily realized on injection moulding or die casting mould; This moment, the shape in the endoporus of valve body also was easy to realize with the structure of loosing core on injection moulding or die casting mould, and the injection moulding of valve body or die casting mould are easy to processing like this; Because valve gap is the part of simple drum, its profile and screw thread are same axis, and top like this internal thread also is easy to realize productions automatic, a plurality of parts on mould; The production of this rubber seal valve just is easy to like this, can reduce the input of mould greatly, has also made things convenient for the automation of producing.
The beneficial effect of the utility model is, can overcome existing rubber seal valve effectively and not be durable, and the shortcoming that difficulty of processing is big, this rubber seal valve mechanism is simple, durable, easy processing, cost are low, easy to use, reliable.
