Abstract
The utility model relates to an anti-siphon valve in a water inlet valve of a water tank of a toilet bowl. The anti-siphon valve comprises a valve seat, a valve and a housing, the valve seat is a cylinder made of flexible materials, a water round hole is arranged in the middle of the valve seat, the water round hole at the front end of the valve seat is reduced, and the tail of the valve seat is connected with a gasket. The valve is a ball, the diameter of the ball is larger than that of the water round hole at the front end of the valve seat but smaller than the inner diameter of the housing, and the ball is heaver than water with the same volume. The housing is a section of water inlet pipe of the water inlet valve, the valve seat and the valve are mounted in the housing, and the gasket at the tail of the valve seat is fastened at the end opening of the water inlet pipe via nuts of a water inlet hose. When water inlet pressure of the water inlet valve is higher than water outlet pressure of the water inlet valve, the valve is separated from the housing, and then water flows into the water tank smoothly. When the water inlet pressure of the water inlet valve is lower than the water outlet pressure of the water inlet valve, the valve and the valve seat are closed, and water can not flow backwards and avoid polluting water resources. The anti-siphon valve can be mounted on various types of novel and conventional water inlet valves.

Anti-siphon valve described in the utility model comprises valve seat, valve and valve body.Described valve seat is a cylindrical shape, and there is the water flowing circular hole centre, and the water flowing circular hole of valve seat front end diminishes, but greater than the inlet valve water outlet, the afterbody of valve seat is connected with packing ring.
Described valve is a ball, or an assemblying body of being made up of head, round platform, cylinder, cylinder and counterweight.
Described ball, diameter are greater than the diameter of the water flowing circular hole of valve seat front end, and less than the internal diameter of valve body, the weight of this ball is greater than the weight of same volume water, and being embedded in has down force in the water.
The head of described assemblying body is a hemisphere, diameter is greater than the diameter of the water flowing circular hole of valve seat front end, internal diameter less than valve body, hemispheroidal disc is connected with the roundlet face of round platform, the big disc of described round platform is connected with cylinder, in the middle of the described cylinder circular hole is arranged, the diameter of this cylinder is less than the internal diameter of cylinder.One end of described cylinder entangles cylinder, and the centre has support that cylinder and cylinder are fused; Space between cylinder and cylinder is a water-filled pipe, and the external diameter of this cylinder is less than the internal diameter of valve body, and cylinder can slide in valve body flexibly.
Described counterweight is fastened in the circular hole in the middle of the cylinder, and the weight of whole assemblying body is brought up to weight greater than same volume ponding, and being embedded in has down force in the water.
Described valve body is one section intake pipe of inlet valve, valve seat and valve are installed in the intake pipe, this intake pipe becomes the valve body and the water-filled pipe of anti-siphon valve simultaneously, the interface of the flexible pipe of using with the connection water source, the packing ring of valve seat afterbody is fastened on the intake pipe port, the water-filled pipe of flexible pipe and anti-siphon valve is connected.
Water intake valve pressure is during greater than inlet valve water outlet pressure, and piston leaves the valve port, and water flows to water tank swimmingly; When water intake valve pressure and inlet valve water outlet pressure maintenance balance, piston sinks, and with the water flowing circular hole closure of valve seat front end, anti-siphon valve is at any time treats working state; When water intake valve pressure during less than inlet valve water outlet place pressure, anti-siphon valve is had an effect immediately, and the water in the water tank can not blow back in the water supply line.
