Abstract

The utility model relates to a siphon-type full-automatic drain valve which is used for flushing sanitary equipment. The siphon-type full-automatic drain valve uses a ball float valve to control the water inlet quantity of a container. A siphon tube of the siphon-type full-automatic drain valve is communicated with the switch of an electromagnetic valve which is controlled by infrared. When human body signal is inducted, the electromagnetic valve is turned on within a certain time, and water can fill up the siphon tube rapidly to form siphonage and open the siphon-type full-automatic drain valve. When power supply is not available, the siphon-type full-automatic drain valve can be opened by hand. The siphon-type full-automatic drain valve has the advantages of good reliability, simple structure, convenient and sanitary use.

Description

Siphon-type full-automatic drain valve

The utility model relates to a kind of sanitary installation, particularly a kind of full-automatic draining valve of hydrocone type infrared control.

Existing low hydraulic pressure, big flow draining valve have following two kinds at present.The one, gravity flow siphon valve.When the water level that discharges water surpassed the syphon cavity, the siphon valve was opened automatically, and water is all towards intact in the water tank, and water level continues to rise behind the valve closing, works again and again.This valve arrangement is simple, but the unlatching of valve do not control because of toilet user's number, and water consumption is very big.The 2nd, with the fully automatic water-saving valve of solenoid control, the water inlet of this valve is controlled by electromagnetic valve switch, and when toilet user's number reaches when a certain amount of, the water level in the water tank reaches the enable possition, the bath of siphon valve open.The shortcoming of this valve has: a, discharge time are influenced by the hydraulic pressure size, daytime during water use peak especially, the water yield seldom, and energising for a long time very easily burns out electromagnetic valve; Can't use when b, power failure; The water yield in c, the water tank can't be adjusted.

The purpose of this utility model is that a kind of novel draining valve will be provided, to solve the deficiency of above-mentioned hydrocone type draining valve.

The technical solution of the utility model is achieved in that being made up of on the hydrocone type draining valve casing, siphon valve, syphon, float valve, an electromagnetic valve and hand-operated valve is set.Two valves are and are connected in parallel, a termination running water pipe, and the other end is connected with siphonal low water stage place by flexible pipe.In order to guarantee to open the siphon valve reliably when the water tank low water stage, on tegmental wall on the siphon valve, have a negative pressure valve, when electromagnetic valve or hand-operated valve were opened water inlet, this negative pressure valve was closed, and making into, water starts the siphon valve effectively.When having a power failure, available hand-operated valve operation discharges water.

Provide embodiment below in conjunction with accompanying drawing.

Fig. 1 is the utility model example structure schematic diagram.

Referring to Fig. 1, complete unit comprises casing 6, siphon valve 7, float valve 10, electromagnetic valve 1, handle valve 2 and syphon 5 and flexible pipe 4.At siphonal low water stage place, a Y-pipe 9 is installed, electromagnetic valve 1 and hand-operated valve 2 are by threeway 3 and are connected in parallel, and two valves are communicated with Y-pipe 9 on the syphon by flexible pipe 4.Water inlet in the casing 6 is subjected to float valve 10 controls, can change the required inflow of primary emission by regulating float valve.Electromagnetic valve 1 is by infrared facility control, as toilet user person during from the lavatory, and electromagnetic valve 1 conducting, tap water enters syphon 5 through electromagnetic valve 1, makes syphon 5 conductings, and siphon valve 7 is opened, and forms big volume exhaust.After the draining, siphon valve 7 cuts out, and float valve is opened water inlet, reaches when demarcating water level, and float valve is closed, and finishes the one action cycle.In case have a power failure, can open hand-operated valve 2 operation drainings.Consider the unlatching reliability of hour draining valve of hydraulic pressure, negative pressure valve 8 is housed on tegmental wall on the siphon valve 7.At ordinary times, this valve is opened, to guarantee siphon valve inside and outside differential pressure balance.When electromagnetic valve 1 or hand-operated valve 2 conductings, water feeding pressure is closed negative pressure valve 8, and making into, water all enters syphon and forms siphon.

The utility model simple structure, good reliability realize full-automatic no touch gauge tap, and regulating pondage as required.
