Embodiment 1

[0023] This embodiment is suitable for being installed under the pool and is similar to the current water return bay type water valve, such as figure 1 As shown, the present invention is a water valve, which is composed of a valve body 8 and a floating valve core 4 arranged in the valve body 8, the valve body 8 is a thick cavity structure in the middle, and the two ends of the cavity are respectively used The water inlet and outlet connected to the drainage pipe network are connected with the cavity in the middle of the valve body; the floating valve core 4 is set in the middle cavity of the valve body 8, which is made of light material A sphere, a hollow sphere, an elliptical sphere or an elliptical hollow sphere can also be a hollow body made of a material with a larger specific gravity, but it must be ensured that the specific gravity of the entire ball is between 0.1 and 0.8, and the outer surface of the floating valve core 4 is in contact with the valve body cavity. The w...

Embodiment 2

[0025] This embodiment is also suitable for being installed under the pool and is similar to the current backwater inlet valve, such as figure 2 As shown, the valve body 8 is fixedly connected by the upper valve body 1 and the lower valve body 2 through threaded engagement, the upper end of the upper valve body 1 is provided with a water inlet, the lower end of the lower valve body 2 is provided with a water outlet, and the water inlet and outlet The nozzle is connected with the upper and lower valve bodies 1 and 2 to form a valve body cavity that is connected internally. Such a structure is convenient for the valve core to be installed in the valve body during the assembly process, and is also convenient for replacing the internal floating valve core 4. The rest of the structure is the same as the embodiment 1.

Embodiment 3

[0027] Such as image 3 As shown, the floating spool 4 is connected with the valve plug 6 which closes the water outlet in the valve body cavity through the connecting rod 5, and the valve plug 6 is provided with a positioning rod 7; the water outlet at the water outlet in the valve body cavity is provided with a positioning pin 3 , There is a circular hole in the center of positioning pin 3, and positioning rod 7 is movable to be arranged in the circular hole of positioning pin 3 and can move up and down. All the other structures are with embodiment 2.

[0028] When there is water flowing into the valve cavity, the floating valve core 4 will generate upward buoyancy, driving the connecting rod 5, valve plug 6, and positioning rod 7 to move upward, so that the valve plug 6 leaves the water outlet in the lower valve body 2, and the lower valve body 2 The water flows down, and after the lower water flows, the floating spool 4 falls automatically under the action of its own grav...

Abstract

A draining water valve is prepared as setting valve body to be cavity structure with water inlet and water outlet at two ends of cavity body, setting float spool at internal of cavity structure and coordinating external surface of said spool to water outlet on cavity body in order to seal water outlet on cavity body when float spool is contacted with said water outlet.

Description

1. Technical field: [0001] The invention relates to a sewer valve, in particular to a sewer valve without an upward turnback structure and not easy to be blocked, which is used under a water pool or a floor drain in a house. 2. Background technology: [0002] In order to prevent harmful gases and cockroaches, rats and other pests in the outdoor sewage pipe network from entering the room through the sewer pipe, people often install water return bays, floor drains and manual water plugs near the indoor sewer outlet to prevent the sewage pipe network from entering the room. Harmful gases and pests enter the room. But all there are some defects in these sewer devices, as the backwater bay and floor drain that are used now, its principle is to utilize the structure in the device to make the sewer flow down in it and then turn back up and then flow down again, so that after the sewer has flowed out, there will be water in the device. Keep some water and use it to separate the ind...
