Abstract
The utility model relates to an inlet valve of water tank. The front half section of an outlet tube is covered in the inlet tube, and the back half section of the outlet tube is connected with a water outlet of an inlet valve. The upper part of the inlet tube is provided with a water storage cavity, and a rubber valve block is arranged on the lower end of the water storage cavity. The rubber valve block is coverd on the upper end of the front half section of the outlet pipe and the upper end of the inlet tube. A branch channel is arranged between the inlet tube and the water storage cavity and the branch channel is provided with a filter screen. The water storage cavity of the inlet valve of the water chamber cannot be clogged by the sundries in the running water, and the quantity of water which flows across the filter screen occupies few or no proportion of the total water which flows into the inlet valve. The filter screen has no need of frequent cleaning and replacement, so the service life of the filter screen can be extended and the speed at which the running water flows into the water chamber can be improved.
Description
Technical field
The utility model belongs to a kind of tank intake valve of water that is used for equipment such as toilet, particularly relates to a kind of tank intake valve of water that utilizes tap water hydraulic that it is closed automatically.
Background technique
Existing hydrostatic tank intake valve of water all is provided with water storage cavity on valve body top, and the underpart of water storage cavity is provided with rubber valve plate, and rubber valve plate covers in the intake pipe upper end-hole.When inlet valve is opened, when water tank replenishes water inlet, water storage cavity is retaining gradually simultaneously also, behind storage full water in the water storage cavity, the hydraulic pressure in the water storage cavity equates that with the hydraulic pressure of tap water rubber valve plate just makes intake pipe seal, whole inlet valve is closed thereupon.After impurity in the tap water accumulates over a long period in water storage cavity with its obstruction, existing tank intake valve of water is provided with filter screen in the middle of intake pipe, impurity in the water just can not flow in the water storage cavity like this, but there is following shortcoming in above-mentioned filtration: 1, all water that enter water tank filter screen of all must flowing through, make the water yield of the filter screen of flowing through big, filter screen will soon stop up, necessary frequent clean, replacing; 2, tap water flows into the speed in the water tank owing to be subjected to the retardance of filter screen through intake pipe, outlet pipe successively, and flow velocity is slow, is unfavorable for making tap water to add in the water tank rapidly.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above existence and a kind of tank intake valve of water is provided, it can make water storage cavity can not stopped up by the foreign material in the tap water, can reduce the water yield of the filter screen of flowing through again significantly, prolong the working life of filter screen, improve tap water and replenish the speed that flows into water tank.
For realizing above purpose, tank intake valve of water of the present utility model comprises intake pipe, outlet pipe, preceding half section of outlet pipe is enclosed within the intake pipe, the second half section of outlet pipe connects the water outlet of inlet valve, be provided with water storage cavity on intake pipe top, be provided with rubber valve plate in the water storage cavity underpart, rubber valve plate covers before outlet pipe the upper end-hole of half section and intake pipe, rubber valve plate places the position limit cycle can be up and down, the water storage cavity upper end also is provided with relief hole, be provided with floating drum and transmission levers in the intake pipe outside, floating drum connects an end of transmission levers, and the other end of transmission levers is positioned at relief hole top, and its main feature is, be provided with branched bottom between intake pipe and water storage cavity, branched bottom is provided with filter component.
Described filter component can be a filter screen.
The utlity model has following advantage and effect:
1, the flow through water yield of filter screen only accounts for the minimum ratio that flows into the inlet valve Total Water, need be few by the water yield that filter screen filters, and filter screen does not need frequent clean, replacing, prolongs the working life of filter screen.
2, water storage cavity can not stopped up by the foreign material in the tap water.
3, filter screen can not block the speed that tap water flows into water tank.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Specific embodiment
Fig. 1, tank intake valve of water shown in 2 comprises intake pipe 5, outlet pipe 3, preceding half section of outlet pipe 3 is capwise and being enclosed within the intake pipe 5, the second half section of outlet pipe is level trend and the water outlet 4 that connects inlet valve, be provided with water storage cavity 9 on intake pipe top, be provided with rubber valve plate 2 in the water storage cavity underpart, rubber valve plate 2 covers the upper end-hole at preceding half section and intake pipe 5 of outlet pipe 3, rubber valve plate 2 places the position limit cycle 12 can be up and down, water storage cavity 9 upper ends also are provided with relief hole 1, be provided with floating drum 11 in the intake pipe outside, floating drum 11 is fixedlyed connected with montant 10, montant 10 connects an end of transmission levers 8, and transmission levers 8 can rotate around its rotating shaft 81, and the other end of transmission levers is positioned at relief hole 1 top, be provided with branched bottom 7 between intake pipe 5 and water storage cavity 9, branched bottom 7 is provided with filter screen 6.
The foregoing description working procedure is as follows: after cistern water level descends, floating drum 11 descends, driving transmission levers 8 rotates, relief hole 1 is opened, and tap water begins to enter valve body through intake pipe 5, and current are divided into two-way, the flow direction is shown in arrow among Fig. 1, wherein one the tunnel flow in the water tanks through intake pipe 5, outlet pipe 3, water outlet 4 successively, another road branched bottom 7 of flowing through filters the back by filter screen 6 and flows into water storage cavities 9.After the rising of water tank middle water level puts in place, floating drum 11 also rises to the upper position of its stroke range, driving montant 10 promotion levers 8 rotates counterclockwise, with relief hole 1 sealing, hydraulic pressure in the water storage cavity 9 is risen to gradually with hydraulic pressure from the beginning to be equated, because the compression area above the rubber valve plate 2 is greater than the compression area below it, the down pressure that rubber valve plate 2 center portions are subjected to is greater than its upward pressure that is subjected to, make rubber valve plate with outlet pipe 3 and the sealing of intake pipe 5 upper end-hole, whole inlet valve is just closed.
Claims (2)
1, a kind of tank intake valve of water, comprise intake pipe, outlet pipe, preceding half section of outlet pipe is enclosed within the intake pipe, the second half section of outlet pipe connects the water outlet of inlet valve, be provided with water storage cavity on intake pipe top, be provided with rubber valve plate in the water storage cavity underpart, rubber valve plate covers before outlet pipe the upper end-hole of half section and intake pipe, rubber valve plate places the position limit cycle can be up and down, and the water storage cavity upper end also is provided with relief hole, is provided with floating drum and transmission levers in the intake pipe outside, floating drum connects an end of transmission levers, the other end of transmission levers is positioned at relief hole top, it is characterized in that: be provided with branched bottom between intake pipe and water storage cavity, branched bottom is provided with filter component.
