Description

Self-closing valve Technical Field The invention belongs to the technical field of valves, and particularly relates to a self-closing valve. Background In daily life, water is sometimes required to be stopped because of the reasons such as maintenance pipelines of tap water companies, during the water stopping period, people habitually open a water faucet to check whether water comes, the water faucet is turned off along the way in most cases, the situation that the water faucet is turned off after leaving home is forgotten, a large amount of water flows and is wasted after the water comes, even the flowing water overflows to the water tank to flow to the ground, the floor is soaked, furniture placed on the floor is soaked, water leakage exists, the roof of a downstairs neighbor is damaged, and the loss is huge. In addition, some public places such as hotels, public toilets, factories, research rooms, schools and the like often have the overflow phenomenon, the environment is tidy and civilized construction is influenced by light water, and properties, equipment and other articles are damaged seriously, so that certain economic loss is brought. The floating ball type overflow prevention controller is 85202023 and is named as a switch of the floating ball type overflow prevention controller, the floating ball type overflow prevention controller consists of a shell, a floating ball, a restorer and a top cover, referring to fig. 1, the floating ball ascends into a cavity at the highest position, gas is collected after water is supplied into the cavity, the collected gas exerts downward force on the floating ball which floats, the floating ball cannot ascend to the highest position, the floating ball is impacted to a pipe orifice by the aid of the impact of flowing water, even the pipe orifice is blocked, water cannot be normally used, when water supply is interrupted, the floating ball falls down to cover the pipe orifice under the action of self gravity, when water supply is recovered, the floating ball can be separated from the pipe orifice due to disturbance of air flow and water flow, the floating ball cannot realize the overflow prevention purpose when no person is filled in the pipe, the floating ball can not realize the overflow prevention purpose when the water flows, the floating ball is firmly clamped at the pipe orifice, the floating ball is difficult to move away normally by pressing the top pin through hands, and the floating ball has the defects that when water is used as follows, the water cannot flow is not drained and the valve cannot be stably removed when no person forgets to finish the overflow prevention. Disclosure of Invention The invention mainly aims to provide a self-closing valve with good anti-overflow effect and convenient opening. The utility model provides a self-closing valve, including the shell, floater and floater return assembly, set up the rivers passageway in the shell, floater return channel, inlet tube and outlet pipe, rivers passageway and floater return channel set up side by side, the lower extreme at rivers passageway is installed to the inlet tube, the upper end at rivers passageway is installed to the outlet pipe, the diameter of floater is greater than the pipe diameter of inlet tube and outlet pipe, the floater is placed in rivers passageway or floater return channel, floater return assembly installs in one side of shell, the operation floater return assembly can make the floater get into floater return channel after the rivers passageway removes, the floater rolls down from floater return channel by the reason of dead weight after cutting off water and gets into rivers passageway. Preferably, a partition plate is arranged between the water flow channel and the floating ball reset channel, a first floating ball passing port and a second floating ball passing port are formed in the partition plate at a preset distance from top to bottom, the first floating ball passing port is close to a water outlet of the water outlet pipe, the bottom of the floating ball reset channel is an inclined surface, the floating ball can roll along the inclined surface at the bottom of the floating ball reset channel to enter the water flow channel through the second floating ball passing port, the floating ball reset assembly is arranged on one side of the water flow channel, and the floating ball reset assembly is operated to push the floating ball to enable the floating ball to move from the water outlet of the water outlet pipe to enter the floating ball reset channel after passing through the first floating ball passing port. Preferably, the first float ball passing opening is provided with a blocking elastic piece, the blocking elastic piece is used for blocking the float ball to pass through the first float ball passing opening due to the impact of water, the float ball reset assembly is operated to push the float ball to squeeze the blocking elastic piece, and the blocking elas
