Description

A kind of gas control draining valve

Technical field

The utility model relates to the double draining valve of water-closet tank, and the controlled way that particularly starts operating mechanism is pneumatic a kind of gas control draining valve.

Background technology

Conventional toilet folk art term draining valve actuating mechanism is mechanical direct press type, make the installation of pushbutton enable mechanism only be confined to the draining valve drainage mechanism directly over, thereby restricted the variation of water tank product-forming and flushing operation mode, this normal discharge valve only is applicable to plug-in dew formula water tank mostly; In order to make full use of the living space, at present existing be hidden in body of wall or bathe in the cabinet concealed water tank, therefore the normal discharge valve is inapplicable, therefore being connected between draining valve and the start-up control mechanism must be that flexible the interlock links, existing line traffic control draining valve adopts wire rope to be connected with spanner, spanner can be installed in the optional position, rotate the full row of control by spanner, partly rank the draining of Cheng Shixian folk art term, make start-up control mechanism no longer be confined to directly over the water valve, but owing to adopt steel wire to half row of draining valve and the control of full seniority among brothers and sisters journey, the steel wire penetrating plastic pipe slides and has frictional force, if the crooked amplitude of plastic pipe 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 needs precisely control, otherwise can cause the disabler or the confusion of line traffic control folk art term draining valve.

The utility model content

Based on the existing problem of above-mentioned draining valve starting drive, the utility model is intended to propose a kind of gas control draining valve, and the installation of its actuating mechanism is not limited by particular location.

The technical scheme in the invention for solving the above technical problem is: a kind of gas control draining valve, the valve body that contains double water, it is characterized in that: the hub cap of valve body is provided with the gas control device, and the gas control device is made up of stroke switching device shifter and stroke generating means and is buckled on the base; Be provided with back-moving spring between limited cover and pull bar in the stroke switching device shifter, be provided with ballonet between pull bar and base; In the stroke generating means, the air cell covering at top entangles air vesicle, and the air vesicle top is connected fixing with the air cell covering top, and air bag is communicated with the hole post that base is provided with; Hub cap is provided with fork, and pull bar and fork touch, and is connected by shadoof between air cell covering top and the conduit that exposes valve body.

The pole top of teasing and ridicule entirely in the utility model valve body is provided with Ka Tai, the fork bottom with tease and ridicule pole entirely and touch and be in the Ka Tai place, when the stroke switching device shifter is worked, pull bar rises and stirs the fork swing that touches with it, the Ka Tai that teases and ridicule entirely on the pole in fork bottom and the valve body breaks away from, remove and tease and ridicule the restriction of pole entirely, make whole row float bucket work, realize the full row function of double water valve body full seniority among brothers and sisters journey.

The beneficial effects of the utility model are: by having installation gas control device on the valve body of double water function, the stroke generating means of gas control device is used to draw high conduit, the work of pole is teased and ridicule in the stroke switching device shifter control of gas control device entirely, makes the different operating state of gas control device control full row and semi-row water function of the present utility model; And the gas control device can be connected with pneumatic button by soft air pipe, and the feasible installation position that starts the pneumatic button of gas control device is equipped with multiple choices, to adapt to the development need of various water tanks.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

As Fig. 1～a kind of gas control draining valve shown in Figure 7, the valve body 16 of double water by draining body 16.1, top be provided with card platform 13.1 tease and ridicule full pole 13, conduit 14, partly arrange keg float 15, whole row float bucket 17, hanger 18, base plate 19, water-drainage base seat 20, sealing rubber cushion 21, valve body 16 lower covers 22, rubber cushion 23 is installed and draining nut 24 frocks form; The hub cap 11 of valve body 16 is provided with gas control device 7, and gas control device 7 is made up of stroke switching device shifter 7.1 and stroke generating means 7.2 and is buckled on the gas control base 8, and the Kong Zhuke under the gas control base 8 is connected with pneumatic button by flexible pipe; 3 on limited cover 1 and pull bar are provided with back-moving spring 2 in the stroke switching device shifter 7.1, and 8 of pull bar 3 and bases are provided with ballonet 4; In the stroke generating means 7.2, the air cell covering 5 at top entangles air vesicle 6, and air vesicle 6 tops are connected fixing with air cell covering 5 tops, and two air bags all are communicated with the hole post that base 8 is provided with; Hub cap 11 is provided with fork 12, pull bar 3 touches with fork 12, fork 12 bottoms touch and are in card platform 13.1 places with teasing and ridicule pole 13 entirely, are connected by shadoof 9 between air cell covering 5 tops and the conduit 14 that exposes valve body 16, and wherein 14 in shadoof 9 and conduit are provided with O RunddichtringO 10.

As Fig. 8～shown in Figure 10, it (is ballonet 4 pressure-controlled of not being bullied that stroke switching device shifter 7.1 in gas control device 7 is not worked, be in original state under the pressure of back-moving spring 2 thereon) and during stroke generating means 7.2 work, promptly pass through gas control device 7 and air vesicle 6 corresponding hole post air inlets, air vesicle 6 drum pressure of being bullied plays jacking air cell covering 5, the shadoof 9 of air cell covering 5 through being attached thereto draws high conduit 14, partly arrange keg float 15 work, drum pressure does not rise because ballonet 4 is bullied, can't pushing rod 3, pull bar 3 can't be stirred fork 12 swings, fork 12 bottoms can't be separated with the card platform 13.1 of teasing and ridicule pole 13 tops entirely, use whole row float bucket 17 not work, so conduit 14 can only be pulled up to the impulse stroke of half row's keg float 15, realize half drain function of the present utility model.

As Figure 11～shown in Figure 13, when all air inlet pressurized work of the post hole of the gas control base 8 of gas control device 7, ballonet 4 drum pressure of being bullied plays jacking pull bar 3, back-moving spring 2 is compressed by pull bar 3 roof pressures, pull bar 3 is stirred fork 12 swings that touch with it, separate with the card platform 13.1 of teasing and ridicule pole 13 tops full fork 12 bottoms, remove the restriction to conduit 14 impulse strokes of teasing and ridicule pole 13 entirely, whole row float bucket 17 work, air vesicle 6 drum pressure of being bullied simultaneously plays jacking air cell covering 5, the shadoof 9 full seniority among brothers and sisters Cheng Lasheng conduits 14 of air cell covering 5 through being attached thereto are realized full drain function of the present utility model.Ballonet 4 action backs reset under the effect of back-moving spring 2, make fork 12 in 14 times backwardnesss of conduit the space that resets be arranged.
