Embodiment 1

[0012] The closed floating ball valve of the present invention consists of a water inlet 1, a water outlet 2, a ball rod connected to a pendulum 3, a push-pull rod connected to a pendulum 4, a push-pull rod 5, a sealing gasket 6, a sealing support 7, a water blocking wall 8 and a valve body 9, one end of the valve body 9 is connected with a ball rod connected to the pendulum block 3, the other end is a water inlet 1, there is a water outlet 2 at the middle bottom of the valve body 9, and a sealed cavity is formed between the water blocking wall 8 and the water outlet 2 , The water inlet end of the water blocking wall has seals 6 and 7, the seals 6, 7 are fixedly connected with the push-pull rod 5, and the push-pull rod 5 is fixedly connected with the pendulum block 4 connected with the push-pull rod. The connection and the function between the push-pull rod connecting the pendulum 4 and the club connecting the pendulum 3 are present technology.

Embodiment 2

[0014] Other parts are the same as in Embodiment 1, and there are 2-6 positioning pieces 10 between the sealing gasket 6 and the sealing holder 7 .

Embodiment 3

[0016] Other parts are the same as in Embodiment 1, and the push-pull rod 5 is movably connected with the pendulum block 4 connected with the push-pull rod.

Abstract

The invention relates to a closed valve and solves the problem that water runs off a water tank over a long period of time in that the water tank cannot be closed tightly caused by the float valve thereof in a reverse water plugging. The closed valve consists of a water inlet (1), a water outlet (2), a ball rod connecting centering block (3), a pull / push rod connecting centering block (4), a pull / push rod (5), a sealing gasket (6), a sealing support (7), a water-plugging wall (8), a valve body (9) and locating plates (10), wherein, the water-plugging wall (8) is arranged between the water inlet (1) and the water outlet (2); a sealing is arranged at the water-entering end of the water-plugging wall (8); 2 to 6 locating plates are arranged on the sealing; a sealing cavity is arranged between the water-outgoing end of the water-plugging wall (8) and the water outlet (2); and the sealing is fixedly connected with the pull / push rod connecting centering block (4). The closed float valve of the invention has the advantages of good sealing effect and reasonable and simple structure.

Description

technical field [0001] The invention relates to a valve, in particular to a water tank float valve. Background technique [0002] In the existing floating ball valve at the water inlet of the water tank, one end of the valve body is connected with a pendulum block, and the other end is the water inlet. The inside of the valve body is hollow and communicated with the water outlet. The nozzle piece and the seal are fixedly connected with the pull rod on the pendulum block through the shaft. When the pendulum swings, the pull rod pulls the shaft to move outward, the seal is separated from the water inlet, and the water flows into the gate valve cavity and then flows into the water tank through the water outlet. , when the water in the water tank is full, the buoyancy of the water makes the pendulum return to its original position, and the pendulum pushes the pull rod, thereby pushing the axis connected to the pull rod to move inward, so that the seal presses the water inlet, an...
