Description

Tool is promoted the valve dredger of cleaning effect

The utility model is a kind of dredger of valve, refer in particular to the cleansing pin or the diaphragm that have helix in a kind of water-closet tank valve and be provided with the helix through hole, when moving up and down at the diaphragm pressurized by this, produce Vorticose current to strengthen the impurity mediation in the valve.

The sealing part that advances of water-closet tank is to be the center with a water inlet pipe 10 as shown in Figure 1, and ball float 11 is located at an end of armed lever 12, the other end then connects one and adjusts termination 13, and make and adjust termination 13 and press downwards and be positioned at water inlet pipe 10 tops one sealing switch 14, water inlet pipe 10 then is installed in water-closet tank bottom 15; General water-closet tank promptly is to utilize the water inlet pipe 10 in these parts to be responsible for water is introduced in the water tank, and ball float 11 is then controlled the water outlet opportunity of water inlet pipe 10 through the adjustment termination 13 of the armed lever 12 effect other ends with the lifting of water level.Though existing water-closet tank all is to utilize ball float 11 to drive armed levers 12 to make and adjust termination 13 compactings or loosen the effect of sealing switch 14 is realized the into control of sealing, but the open type of sealing switch 14 but is divided into two kinds of direct sealing formula and diaphragm sealing formulas; The former directly stops delivery port in the water inlet pipe downwards by the adjustment termination of ball float actuating arm rod end, water is no longer flowed out, and the latter utilizes pressure balanced mode, utilize the less pressure that ends to make the huge downforce of the interior generation of sealing switch remove to suppress diaphragm obstruction water inlet pipe delivery port, reach the control of water outlet; In these two kinds of sealing switches, directly the sealing formula need design big ball float and long-armed bar to produce bigger sealing pressure, and this measure easily enlarges the volume of water tank, has not gradually met the life requirement in the little space of household at present; But the valve in its switch is difficult for the impurity obstruction takes place, and arranged long application life.Compared to the design of the large volume of direct sealing formula switch, diaphragm type sealing switch is not owing to need excessive sealing pressure, so ball float and armed lever all dwindled, and creates the water tank of smaller size smaller; But this kind sealing switch is to utilize pressure differential to advance the control of sealing, and the small finedraw between diaphragm and cleansing pin is easy to be blocked by impurity in the water and can't operate in its switch; Be must strict control with the use water quality of this type of switch.

As shown in Figure 2, has a stopper 140 that directly touches with adjustment termination 13 in the diaphragm type sealing switch 14, stopper 140 is placed in the spring 141 and installs above the pore 143 that sealing switch top cover 142 is offered, pore 143 belows then are another diaphragm 145 of being shored by spring 144, the cleansing pin 146 of planting in the middle of the diaphragm 145; This sealing switch is to utilize armed lever 12 to drive adjustment termination 13 to press down stopper 140 obstruction pores 143, make the air chamber 147 of 145 on stopper 140 and diaphragm produce pressure and diaphragm 143 is pressed down make the intermediate portion block water inlet 148, and water can't be flowed in the water tanks by delivery port 149.The place that the easiest generation impurity blocks in diaphragm type sealing switch is cleansing pin 146 and diaphragm 145 cooperation places, and as shown in Figure 3, the stopper 140 of diaphragm 145 inside has a centre bore 1451, and cleansing pin 146 just thus centre bore 1451 run through; Centre bore 1451 is as the water source that replenishes in the air chamber 147, so that the pressure that presses down diaphragm 145 to be provided; And the aperture of centre bore 1451 is related to the speed that the water source replenishes, and and then influences the speed of water tank water intake.The aperture of this centre bore 1451 is all very narrow and small; For being blocked by impurity in anti-narrow and small here aperture, so establishing a cleansing pin 146 runs through centre bore 1451, affect centre bore 1451 on cleansing pin 146, to move when making diaphragm 145 upper and lower displacements, use the impurity of removing in the centre bore 1451, prevent from diaphragm switch to be operated because of centre bore 1451 blocks.Traditional cleansing pin 146 and centre bore 1451 all are designed to level and smooth surface, and when diaphragm 145 moved up and down, 1451 of cleansing pin 146 and centre bores produced the current that wash away of straight line, so that impurity in the water is gone out outside the diaphragm 145; Traditional cleansing pin 146 and centre bore 1451 be not because to be subject to distance and the speed that diaphragm 145 is shifted up and down be very big, so it also is very light and slow occurring in the water velocity of washing away of 1451 of cleansing pin 146 and centre bores, like this to wash away water velocity limited really to the removing of impurity, and fail to bring into play actual effect as and if the setting of cleansing pin 146.

In diaphragm switch, diaphragm produces displacement because of the pressure action, and its speed that moves is difficult to the jumbo to some extent increase and decrease with the variation of pressure, desires mat and changes pressure and the diaphragm shifting speed is speeded, and then promote the water velocity of washing away between cleansing pin and diaphragm centre bore, in fact rather have obstacles and be difficult to walk.In view of this, desire is promoted the water velocity of washing away between diaphragm centre bore and cleansing pin, goes to set about to improve from cleansing pin or centre bore, and seemingly feasible road, the utility model promptly are based on this notion and develop.

At the shortcoming of prior art, this novel purpose is that the surface with helix is made on level and smooth cleansing pin or centre bore surface commonly used, and a kind of spiral cleansing pin or spiral centre bore promptly are provided; This spiral cleansing pin is in the planar central hole of inserting diaphragm, or the plane cleansing pin inserts the centre bore of diaphragm tool helix, then when the diaphragm pressurized and when cleansing pin moves up and down, can form one vortex water flow between diaphragm centre bore and cleansing pin, this vortex water flow has the unexistent revolving force of straight current, impurity in the water between cleansing pin and diaphragm centre bore can be discharged rapidly in diaphragm; So, promptly have under the translational speed, can make the stronger vortex water flow of generation between cleansing pin and diaphragm centre bore, effectively get rid of the impurity that accumulates in diaphragm, make the normal function of the normal guarantor of diaphragm at diaphragm; I.e. this: the cleansing pin surface at the diaphragm in diaphragm type sealing switch has helix, or the hole wall of the diaphragm through hole that cleansing pin ran through is provided with helix novel it is characterized in that; When adopting spiral helicine cleansing pin, the hole wall of the diaphragm through hole that it runs through is a flat face; When the hole wall of diaphragm through hole had helix, the cleansing pin surface of then running through was flat face.
