Description
Technical field
The utility model relates to the starting drive of the double draining valve of water tank, is particularly useful for the pneumatic button of a kind of water tank drain valve of non-top-push draining valve requirement.
Background technology
Common folk art term draining valve pushbutton enable mechanism is mechanical direct press type, the pressing force of button haptic element is directly exported, directly press the contact of arguing for the sake of arguing on the folk art term draining valve by haptic element, thereby start the drain function of draining valve, this mechanical fit system, make the installation of pushbutton enable mechanism only be confined to draining valve directly over, the Cistern flushing operative orientation is single; And present bathroom industry development is rapid, the existing line traffic control draining valve of draining valve, it can connect steel wire by spanner and start draining valve, multiple choices have just been looked in the installation site of spanner, therefore be not limited only to directly over the draining valve for the installation requirement of water tank drain valve actuating mechanism, but because what adopt is that steel wire passes plastic pipe and slides, but still have frictional force to exist, if the bending amplitude is big or bending more for a long time, the increase of its frictional force will influence the startup of actuating mechanism to draining valve; Moreover the stroke of steel wire need precisely be controlled, otherwise can cause the disabler or the confusion of line traffic control folk art term draining valve; Therefore demand developing a kind of quick and easy for installation, good stability urgently and be not subjected to the draining valve starting drive of installation site constraint.
The utility model content
For solving the existing problem of above-mentioned draining valve starting drive, the utility model is intended to propose compact conformation, volume is less, installation position is not subjected to the draining valve constraint the pneumatic button of a kind of water tank drain valve.
The technical scheme in the invention for solving the above technical problem is: the pneumatic button of a kind of water tank drain valve, to arrange button and its complete down row's guide pillar engagement connection entirely, compressing gasbag is with back-moving spring in the body, the bottom of body bottom and compressing gasbag snapping, the column jecket that full row's guide pillar passes compressing gasbag and bottom plugs together, dial hood entangles full row's button and withstands its convex annular edge down, and dial hood is connected with the body interference fit, and locking nut and body outer wall screw; It is characterized in that: bottom has valve body integrated with it, upper and lower air vent and two Kong Zhu that are communicated with it that are respectively equipped with of valve body, be provided with column type air guide spool in the valve body, be provided with spring in the space between bottom, valve body chamber and the spool, spool is provided with the annular groove that the O RunddichtringO is installed, and the O sealing ring is in post mouth edge, hole; Spool is provided with the passing contact and exposes outside the valve body chamber; In body cavity, be provided with half row's guide pillar, partly arrange guide pillar with arrange partly that button engage and and full row's button guide pillar overlap, the passing inclined-plane of partly arranging bottom the guide pillar contacts mutually with passing contact on the spool.
In the utility model, be provided with the stroke limit groove, fixture block that spool is provided with and the screens of stopper slot end with the integrated valve body of bottom; Air vent in the column jecket is communicated with the valve body chamber, and the hole post pore of valve body below is communicated with the valve body chamber; Spool stroke portion in the air vent correspondence is provided with air guide chamber groove, and the annular groove that the O RunddichtringO is installed is on the spool at groove two ends, air guide chamber; The groove width of air guide chamber groove equals two Kong Zhukong distance in the heart, also equals the flute length of stopper slot.The annular groove that an O RunddichtringO perhaps only is installed is between the Kong Zhu and stopper slot of the most close stopper slot, the spool of annular groove between at the bottom of the valve body chamber partly is air guide chamber groove, air guide chamber groove is communicated with air vent, press down the passing inclined-plane roof pressure spool indentation that makes on it by partly arranging guide pillar, make current path change, be used to control the startup of the stroke switching mechanism of the mozzle on the draining valve, realize the full row and semi-row function of draining valve.
The beneficial effects of the utility model are: with bottom that air bag is communicated with below be provided with an air guide valve body, the passing contact that exposes by the spool that is in the valve body with partly arrange button and lead the passing inclined-plane of bottom and push up interlock mutually, make spool indentation valve body chamber, the position of the O RunddichtringO by air guide chamber groove end changes, make the gas passage in the valve body change, realization is to the start-up control function of gas control folk art term draining valve, and because this novel employing flexible pipe is connected with the actuating mechanism of draining valve, therefore installation site of the present utility model is not limited.
