Abstract

Provided is an anti-siphon structure of a water tank inlet valve. The top of the valve body extends with a first pipe ring communicated with a valve body water inlet channel. A second pipe ring sleeves the outer side of the first pipe ring at interval. The inner wall edge of the second pipe ring is provided with a launching hole communicated with a water outlet pipe. A guiding pipe ring is disposed between the launching hole and the first pipe ring. A rectifier in the guiding pipe ring cooperates with the first pipe ring and the guiding pipe ring at interval. A gland combines with the second pipe ring, forming a water outlet cavity. The top of the gland is provided with a plurality of air inlets communicated with the water outlet cavity. An anti-siphon rubber mat which seals the upward air inlet or a downward water spraying mouth is disposed between the gland and the water spraying mouth. When water flows in from the water outlet cavity, the anti-siphon rubber mat slides upward to seal the air inlet, blocking air from flowing in the water outlet cavity. When the water inlet pipe is blocked, the anti-siphon rubber mat slides downward to open the air inlet, air flows in the water outlet cavity, blocking the siphon and preventing water in the water tank from flowing back to the water inlet pipe to pollute water source. The utility model is advantageous in that no back pressure valve is disposed in the water outlet cavity; the gland can be provided with more air inlets; the anti-siphon effect is bettered.

Description

A kind of anti-syphon structure of tank intake valve of water

Technical field

The utility model relates to the anti-syphon structure of toilet tank intake valve of water, particularly a kind of tank intake valve of water.

Background technology

Existing tank for excrement pan water intaking valve mostly possesses anti-siphon function, as the disclosed a kind of anti-syphon valve inlet of Chinese patent (notification number CN201250431Y), it is at the shunting disk 4 at water inlet pipe 1 top, sealing gland 3 bottoms are equipped with sealing rubber cushion 5, form the valve pocket 30 that an intake tunnel and outlet pipe are communicated with between gland 3 and the shunting disk 4, gland 3 is provided with and is communicated with the inside and outside gas supplementing opening 301 of valve pocket 30, and it is can be between the two movable to stop up exhalant canal 42 water inlet ends 421 and intake tunnel 41 water sides 411 or to stop up the anti-siphon rubber cushion 6 of described gas supplementing opening 301 to be provided with between shunting disk 4 and the gland 3; There are the following problems for the anti-syphon structure of above-mentioned water intaking valve: the sealing rubber cushion 5 of 1. controlling water inlet pipe water inlet or sealing is installed with 6 while of the anti-siphon rubber cushion fit of control valve pocket 30 air inlets, increase the complexity of structure assembling greatly, anti-siphon effect and functional reliability are lower; 2. need to be provided with a lot of gas supplementing openings 301 on the gland 3 and prevent siphon effect preferably to get, but limit by the intensity of gland 3, gas supplementing opening 301 can't be provided with too much, and therefore anti-siphon effect is relatively poor.

The utility model content

For solving above-mentioned gas supplementing opening too much gland intensity and the anti-siphon functional reliability problem of raising of influencing can not be set, the utility model is intended to propose a kind of anti-syphon structure of tank intake valve of water.

The technical scheme that the utility model addresses the above problem employing is: a kind of anti-syphon structure of tank intake valve of water, contain one and water inlet pipe, the valve body that outlet pipe connects, first pipe ring of valve body top extension one and valve inleting water channel connection, be placed in second pipe ring in first pipe ring outside at interval, the valve body at the second pipe ring inwall edge is provided with the drainage hole that is communicated with outlet pipe, it is characterized in that: on the valve body between the drainage hole and first pipe ring, be provided with a shrouding ring, cover unification rectifier in the shrouding ring, the rectifier and first pipe ring, shrouding ring cooperates at interval, is spaced apart water jet between shrouding ring and the rectifier; The gland and second pipe ring constitute water chamber, and the gland top is provided with some air inlets that are communicated with water chamber, are provided with upwards shutoff air inlet or the anti-siphon rubber cushion of shutoff water jet downwards between gland and the water jet.

Gland described in the utility model or rectifier are provided with an endless tube, and anti-siphon cushion cover moves up and down on endless tube and along it, and preferential the employing in the gland bottom of the utility model is provided with this endless tube.

Rectifier inner top described in the utility model is provided with a deflection cone, and described rectifier is a cylindrical duct, is interval with the some muscles that extend outstanding rectifier bottom on the rectifier lateral wall, and muscle makes rectifier cooperate with shrouding ring border and bottom interval; Perhaps described rectifier is a cylindrical duct, and the base of cylindrical duct is provided with some projections that rectifier is cooperated with the shrouding ring bottom interval; Deflection cone can be entering the water uniform ring of water chamber from first pipe ring to water conservancy diversion, make current after rectifier is handled, can evenly gush out at a high speed, promote anti-siphon rubber cushion along the air inlet on the endless tube slip rising shutoff gland of gland bottom through the water jet that rectifier bottom, rectifier lateral wall and shrouding ring form at interval.

Rectifier of the present utility model top contacts mutually with the endless tube bottom, and rectifier is fixed in the shrouding ring, and the rectifier top avoids the endless tube on anti-siphon rubber cushion and the gland to break away from along shelving anti-siphon rubber cushion simultaneously; Rectifier perhaps of the present utility model top and endless tube bottom socket, the rectifier top directly is installed on the endless tube it along shelving anti-siphon rubber cushion.

The beneficial effects of the utility model are: fasten by gland and second pipe ring and form water cavity, and during the water chamber water inlet, the anti-siphon rubber cushion shutoff air inlet that upwards slides, the blocking-up air enters water chamber; In water inlet pipe when cutout,, the anti-downward sliding opening air inlet of siphon rubber cushion, air enter water chamber blocking-up siphon, promptly avoid the water chamber negative pressure form siphon the aqueous reflux in the water tank back into the waterpipe polluted source; The counterbalance valve of control water inlet is not set in the utility model water chamber, so structure is more simple, it is more quick to assemble, and gland can open more air inlet, anti-siphon effect is better.
