The utility model has the advantages that: no external stress is exerted on the lower plane and upper plane of the water-sealing rubber; the water-sealing result is improved; at the same time, the installation of the drain valve is more convenient.
Description
The utility model relates to a kind of valve cover structure of draining valve, is specially adapted to the valve cover structure of the draining valve in the toilet water tank.
The valve gap of the draining valve in the toilet water tank in the market, include hollow pot, following hollow pot and the water sealing aprons that gripping between the hollow pot up and down are (as the patent No.: 99235663.6 and 96221242.3), because hollow pot two planes up and down of gripping water sealing aprons up and down, make water sealing aprons produce a kind of applied stress, cause the water sealing aprons distortion, make the draining valve in the toilet water tank produce drainage.In addition, the hollow pot up and down of valve gap is formed a hollow ball or microscler hollow body, when on the drain hole that draining valve is installed in the toilet water tank, need dig valve gap about 90 °, at this moment, the following hollow pot of valve gap just blocks the screw on the connector of the drain hole in drain valve seat and the toilet water tank, is above screw tightening extremely inconvenient and extremely difficult with screwdriver.
According to above situation, the purpose of the new shape of this practicality is to provide two planes up and down of water sealing aprons of valve gap of a cover draining valve without any applied stress, reduces the distortion of water sealing aprons, thereby reduces the drainage of the draining valve in the toilet water tank.Equally also the volume of the following hollow pot of valve gap being reduced to minimum, is extremely convenient and easy for being fixed on the screw tightening on the connector of drain valve seat on the drain hole in the toilet water tank with screwdriver.
The purpose of this utility model is achieved in that the valve gap of this draining valve, comprise the time-delay tube, there is an arm of force to be connected versatilely on the bearing support of drain valve seat on the time-delay tube, the tube bottom that it is characterized in that delaying time fixedly connected the last hollow pot of valve gap, fixedly connected water sealing aprons axle below the last hollow pot, seal in water sealing aprons on the water sealing aprons axle, water sealing aprons centre bore and water sealing aprons axle are being closely cooperated.Be fixed on the water sealing aprons axle (water sealing aprons axle and the plastic sealing water also available glue be adhesively fixed of piece of encircling for protection, or be linked to be an integral body to both) in the lower end of water sealing aprons axle with the key screw plastic sealing water piece of encircling for protection so long.Make the plastic sealing water piece of encircling for protection protect water sealing aprons and can not lose downwards, and must not clamp water sealing aprons, make water sealing aprons up and down the plastic sealing water of the last hollow pot of two planes and upper connector and the following connector piece of encircling for protection maintain certain clearance, guarantee that water sealing aprons does not apply any applied stress in two planes up and down, makes water sealing aprons swing up and down freedom.And to lower plane process frosted processing on the water sealing aprons, make it to be the frosted shape, eliminate the mirror status of lower plane on the water sealing aprons, water sealing aprons can't be bonded together by water with last hollow pot lower surface under any state, because when the draining valve draining, the valve gap of draining valve is upwards dug about 90 °, when the water in the water tank drains, valve gap leaves behind automatically, at this moment, under action of gravity, water sealing aprons must move upward, pasting the following transverse plane of going up hollow pot, between the two air is being extruded and forming negative pressuren zone, therefore on the lower limb of last hollow pot, having several apertures or have some radioactivity striped in the lower surface of last hollow pot, make air from these apertures or radioactivity striped, enter negative pressuren zone between hollow pot lower surface and the water sealing aprons, thereby the negative pressuren zone on the destruction between hollow pot lower surface and the water sealing aprons, make above both be not bonded together by water, and reduce draining valve drainage in the toilet water tank.
Be further described accompanying drawing the 1, the 2nd, the valve cover structure schematic diagram of this draining valve below in conjunction with the valve gap of accompanying drawing to this draining valve.The valve gap of this draining valve by the upper end of last hollow pot (8) fixedly connected time-delay tube (10), last hollow pot (8) lower end fixedly connected water sealing aprons axle (7), water sealing aprons axle (7) seals in water sealing aprons (5), with screw (9) the plastic sealing water piece (4) of encircling for protection is fixed on the water sealing aprons axle (7), and make two planes up and down of water sealing aprons (5) and last hollow pot (8) and the plastic sealing water piece (4) of encircling for protection keep certain interval, water sealing aprons (5) is swung up and down freely, and the last lower plane of assurance water sealing aprons (5) is not subjected to any applied stress provides possibility.Water sealing aprons (5) two planes is up and down handled through frosted, and be the frosted shape, eliminate water sealing aprons (5) mirror status on two planes up and down, water sealing aprons (5) can't be bonded together by water with the lower surface of last hollow pot (8) under any state, and on the lower limb of last hollow pot (8), have several apertures (6) or have some radioactivity striped in the lower surface of last hollow pot (8), air can enter from these apertures or radioactivity striped between hollow pot (8) and the water sealing aprons (5), and water sealing aprons (5) is not bonded on the following transverse plane of hollow pot (8) by water.
Drain valve seat (3) fixedly is installed on the drain hole in the toilet water tank, with screwdriver the screw (1) in the connector (2) being tightened is extremely easily, because when drain valve seat is installed, valve gap is dug about 90 °, as the state of accompanying drawing 2, plastic sealing water piece (4) volume of encircling for protection is very little, and has left the drain hole center line of draining valve, also be the center line of screw (1), it is extremely convenient with screwdriver screw (1) being tightened.
