Description

A kind of outlet valve of flushing device for toilet water tank

The utility model belongs to the outlet valve of the parts of lavatory flushing device for toilet, particularly a kind of water tank.

The water tank outlet valve of the present lavatory flushing device for toilet that generally uses, structure comprises valve seat, closed rubber parts, switch handle, swing arm, gimmal, wherein valve seat has water outlet and spill-over mouth, the switch handgrip is installed on outside the water tank, swing arm is positioned at water tank and is connected with the switch handgrip, gimmal one end is fixed on the swing arm afterbody the other end and is fixed on closed rubber parts top, and closed rubber parts is connected by its edge lug and valve seat strand.Can be by the operating switch handgrip carrying on the gimmal or putting down, so that closed rubber parts is opened or borrow water pressure to close the water outlet of valve seat.Because the sectional area of gimmal is less, is subjected to easily to be broken behind the aqueous corrosion, this has caused very big inconvenience to use, has also increased the work of maintenance.

The purpose of this utility model provides a kind of outlet valve of improved flushing device for toilet water tank, replaces gimmal with corresponding coupling component, makes it to be difficult for being damaged, and can reduce maintenance work.

The utility model is achieved in that a kind of outlet valve of flushing device for toilet water tank, comprise valve seat, closed rubber parts, switch handgrip, swing arm, Sealing, water outlet and spill-over mouth are wherein arranged on the valve seat, the switch handgrip is installed on outside the water tank, swing arm is positioned at water tank and is connected with the switch handgrip, it is characterized in that closed rubber parts is loaded on the fitting seat, lifting arm, its lower end are connected on the fitting seat, are placed through the pilot hole of valve seat in the middle of it, its upper end has an ailhead to move in the elongated slot that is engaged on the swing arm.

Such scheme replaces gimmal as middle coupling component with a lifting arm, and its sectional area is bigger, and the damage that is difficult for being corroded can make maintenance work reduce.In order to guarantee the join strength of lifting arm and closed rubber parts, establish a fitting seat at closed rubber parts top, lifting arm is connected with fitting seat.In order to make lifting arm that good vertical lift performance be arranged, establish a pilot hole on the valve seat and place thereon for lifting arm, swing arm is provided with elongated slot and does mobile the cooperation with the ailhead of lifting arm simultaneously.It is more direct to use above-mentioned lifting arm to close water outlet, and it is also more convenient effectively to grasp the water-outlet quantity size as required.

Below in conjunction with accompanying drawing the utility model is done further to describe.

Fig. 1 is the vertical profile schematic representation of the installment state of a kind of scheme of the utility model.

Fig. 2 is the plan view of Fig. 1.

With reference to Fig. 1～Fig. 2, this outlet valve, comprise valve seat 1, closed rubber parts 2, switch handgrip 3, swing arm 4, Sealing 5 etc., water outlet 6 and spill-over mouth 7 are wherein arranged on the valve seat 1, switch handgrip 3 is installed in outside the water tank 8, swing arm 4 is positioned at water tank 8 and is connected with switch handgrip 3, feature is that closed rubber parts 2 is contained on the fitting seat 9, and lifting arm 10, its lower end is threaded on the fitting seat 9, be placed through in the pilot hole 11 of valve seat 1 in the middle of it, its upper end has an ailhead 12 to move in the elongated slot 13 that is engaged on the swing arm 4.In addition, the closing face 14 of closed rubber parts 2 is made the spherical crown shape, and closed performance is better also more durable like this; Also be provided with a revolute joint 15 in the middle of the swing arm 4, to increase operational flexibility; Valve seat 1 also be provided be equipped with on the support 16, support 16 of a protrusion one by small floating ball 17 controls withhold device 18, be used for fixing the lowering position of lifting arm 10; Also have a nut 19 to be used for valve seat 1 is locked at water tank 8 on the valve seat 1.

Advance full water in the water tank 8 during use, lifting arm 10 is in lowering position, and fitting seat 9 is subjected to water pressure and pushes closed rubber parts 2 and close water outlet 6, and small floating ball 17 come-ups are withheld device 18 and withheld lifting arm 10 from the side to fix its lowering position.When the needs water outlet, switch handgrip 3 lower plates, swing arm 4 afterbody perks, lifting arm 10 is raised, and drives closed rubber parts 2 and opens water outlet 6, and the water of water tank 8 pours bedpan from water outlet 6.Ailhead 12 can move in elongated slot 13 between lifting arm 10 buck stays, and joint 15 also can have in a small amount rotates, and can overflow from the spill-over mouth when the water level in the water tank 8 is too high.
