Installing the utility model in the siphon toilet chair water tank can not only better wash the washing surface of the toilet chair, but also better avoid the second time reflex pollution. The utility model is compact in structure, reliable in performance.
Description
The utility model relates to a kind of toilet cistern fittings, particularly low cistern toilet cistern fittings commutation water-feeding valve.
At present, hydrocone type low cistern toilet is lower than the flushing surface of toilet because of the water outlet height of its weep hole, the moisturizing of toilet, the flushing of flushing surface must utilize pressure of supply water, most of inflow of certain hour moisturizing and enter flushing surface respectively in the water inlet process, the remaining water yield just enters the toilet water tank.Finish above-mentioned work must water feed apparatus install additional one the commutation water-feeding valve realize.Yet, the deadweight that interior buoyancy of water of toilet water tank or water are all depended in the commutation action of existing common low cistern toilet cistern fittings commutation water-feeding valve realizes, so exist following drawback: 1, cross when low, too much or not the commutate phenomenon of action of moisturizing occurs when pressure of supply water.2, the working portion of commutation moisturizing valve body is immersed in the water for a long time, and incrustation scale is adsorbed on its surface easily, causes its rough surface injustice, has increased frictional force, influences the reliability of its commutation action.3, when the volume of toilet water tank big and need water displacement hour because the height of water is little,, can't realize that commutation moves so be difficult to reach the required stroke of commutation.4, rate of water make-up increases with pressure of supply water, the phenomenon that the secondary bath often occurs or waste water.
The purpose of this utility model is that a kind of low cistern toilet cistern fittings commutation water-feeding valve will be provided, to overcome the existing the problems referred to above of present common commutation water-feeding valve, make it not depend on the deadweight of interior buoyancy of water of toilet water tank and water, commutation water-feeding valve body running part is away from the water surface of toilet water tank, rate of water make-up is little with the fluctuation of hydraulic pressure, thereby the commutation of water inlet and moisturizing action is reliable and stable.
The purpose of this utility model is achieved in that when in original state the utility model low cistern toilet cistern fittings commutation water-feeding valve has commutation function and can make the changeover valve core of water (flow) direction change be in the moisturizing direction under the effect of commutation floating drum.When inlet valve was just intake, water entered the moisturizing state, and little water enters the commutation water tank by the cubic hole in the outlet passage, along with the water level in the commutation water tank rises, the floating drum that will commutate floats, and makes changeover valve core be in into water direction, makes water enter in the toilet water tank.When the water of toilet water tank is full make inlet valve stop into water to setting height after, along with the water in the commutation water tank flows in the toilet water tank by its aperture that leaks, the commutation floating drum falls voluntarily because of losing buoyancy of water, makes changeover valve core be in the moisturizing direction again.At this moment, just finish the into commutation process of water and moisturizing.
Below in conjunction with accompanying drawing structure of the present utility model is further described:
Fig. 1, be structural representation of the present utility model.
In the drawings, the utility model low cistern toilet cistern fittings commutation water-feeding valve is by commutation moisturizing valve body (4), be installed in the commutation moisturizing valve body (4) and have the changeover valve core that commutation function is the plow harrow shape (6), commutation water tank (1), be installed in the commutation floating drum (3) in the commutation water tank (1), and can make that commutation floating drum (3) is floating to fall and the reversing shaft (7) of changeover valve core (6) rotation constitutes, the left side of commutation moisturizing valve body (4), the right side respectively has the hole with the below and is connected outlet passage (2) respectively, water-adding pipe (5) and outlet pipe (8), commutation water tank (1) and commutation floating drum (3) are connected in an end of reversing shaft (7), commutation moisturizing valve body (4) and changeover valve core (6) are connected in the other end of reversing shaft (7), changeover valve core (6) rotates around reversing shaft (7) in commutation moisturizing valve body (4), it is along with the position that be used for change himself of the SEA LEVEL VARIATION in commutation water tank (1) by commutation floating drum (3) makes the water (flow) direction change, thereby reaches the commutation effect of water into or moisturizing respectively.
When the supporting inlet valve that is connected with outlet passage (2) also do not have water to enter or when just having begun to intake, commutation floating drum (3) does not float because of can not get buoyancy of water, makes changeover valve core (6) be in the B position with limit function, at this moment, is the moisturizing state.Water intake valve, feed water flow is to the moisturizing direction, have only a spot of water to enter commutation water tank (1) by the cubic hole C in the outlet passage (2) that is connected with inlet valve, and the water yield size that flows to commutation water tank (1) can be regulated by being installed between commutation water tank (1) and the outlet passage (2) the moisturizing adjusting screw in connecting tube.Along with the water level in the commutation water tank (1) progressively raises, the floating drum (3) that will commutate slowly floats, because of reversing shaft (7) is connected with changeover valve core (6) with commutation floating drum (3) respectively, also driving changeover valve core (6) when commutation floating drum (3) come-up rotates a certain angle, make changeover valve core (6) be in the A position, thereby changeover valve core (6) is closed the current of moisturizing direction.At this moment, change has taken place in the flow direction of water, and enters in the toilet water tank by outlet pipe (8), and this is a water state into.When the water of toilet water tank is full make inlet valve stop into water to setting height after, the water in commutation water tank (1) flows in the toilet water tank by the aperture D that leaks of its bottom, the floating drum (3) that commutates falls voluntarily because of losing buoyancy of water.Falling of commutation floating drum (3) also drives the B position that changeover valve core (6) has rotated to position-limiting action by reversing shaft (7).At this moment, changeover valve core (6) is in the moisturizing direction again.So, just, finish the into commutation process of water and moisturizing.Then, enter work cycle next time.
Can determine according to the size of pressure of supply water, inflow the turn around time of the utility model water inlet and moisturizing, also can determine by regulating the moisturizing adjusting screw.When the hydraulic pressure that supplies water was low, water flow was little, and the commutation needed time of water inlet and moisturizing is long; When hydraulic pressure was high, water flow was big, and the commutation needed time of water inlet and moisturizing is short, and the rate of water make-up that obtains almost is constant.Like this, the problem that changes with variation in water pressure with regard to the rate of water make-up that has solved the toilet water tank.
The deadweight of interior buoyancy of water of toilet water tank and water is not depended in the commutation action of the utility model low cistern toilet cistern fittings commutation water-feeding valve, and its working portion has guaranteed the commutation reliability of water inlet and moisturizing away from the water surface in the toilet water tank.In hydrocone type toilet water tank, the utility model is installed, can be washed the flushing surface of toilet well, can avoid secondary back to pollute again preferably.Its rate of water make-up is little with the variation of pressure of supply water, has characteristics such as compact structure, reliable in action, long service life.
