Description
Technical field
The utility model relates to the toilet tank intake valve of water, particularly a kind of water tank anti-syphon valve inlet.
Background technology
The toilet tank intake valve of water is connected with water supply pipe, when water supply pipe stops or hangs down hydraulic pressure, be connected water intaking valve with it and can produce negative pressure and cause water siphon in the toilet cistern to be flow backwards back polluting water supply pipe, therefore the toilet cistern water intaking valve mostly has anti-siphon function at present; The disclosed a kind of anti-syphon valve inlet of China's utility model patent (CN201250431), it is provided with can be between the two movable anti-siphon rubber cushion 6 to stop up described exhalant canal 42 water inlet ends 421 and intake tunnel 41 water sides 411 or to stop up described gas supplementing opening 301 between shunting disk 4 and gland 3, the shunting disk 4 of this water intaking valve comprises a disk body 401 and one and the chassis 402 that is welded as a whole of this disk body 401, and this chassis 402 is formed by water inlet pipe 1 top outer extension.The problem that above-mentioned water intaking valve exists mainly contains:
1.Intake tunnel 41 and exhalant canal 42 all are located on this shunting disk 4, are made the structure of shunting disk 4 too complicated, the die sinking cost increases, and the contraposition problem that causes follow-up shunting disk 4 and chassis 402 welding on the water inlet pipe 1 to assemble;
2.Because intake tunnel 41 and exhalant canal 42 all are located on this shunting disk 4, therefore need earlier water side 422 contrapositions on exhalant canal on the shunting disk 4 42 and the chassis 402 when this shunting disk 4 is with chassis 402 welding, therefore packaging efficiency is low, and may occur causing the fraction defective of product to heighten because of wrong contraposition welding.
The utility model content
For addressing the above problem, the utility model is intended to propose a kind of simple in structure, a kind of efficiently water tank anti-syphon valve inlet of assembling.
The technical scheme that the utility model addresses the above problem employing is: the water tank anti-syphon valve inlet, containing outlet pipe and top epitaxial lateral overgrowth has the water inlet pipe of disk, top sides is connected the outlet pipe top along the gland that is provided with some air inlets, be provided with the sealing rubber cushion in the gland, be provided with a shunting disk between sealing rubber cushion and the disk, the sealing rubber cushion is placed in the shunting disk top and fits with the water inlet pipe top, it is characterized in that: the shunting disk edge is provided with the pod apertures of its top of some connections and bottom, and the shunting disk bottom is provided with the split channel that is communicated with pod apertures; Water inlet pipe and shunting disk are tightly connected; The gap between shunting disk top, shunting disk side and the gland and the water outlet breach of outlet pipe constitute an exhalant canal, and exhalant canal is communicated with pod apertures; Be provided with between shunting disk and the gland and can move up the shutoff air inlet or move down the anti-siphon rubber cushion of shutoff pod apertures.
Described disk side is provided with an annular groove, is with sealing ring in the annular groove, and shunting disk, sealing ring, water inlet pipe fit or engagement connection make intake tunnel separate with exhalant canal.
Described disk below is provided with the cyclone that makes the current noise abatement, and the water of the feasible outlet pipe of flowing through of this cyclone forms the centrifugal force discharge fast and lays out pipe inner wall and flows down, to avoid producing the flowing water noise.
Described disk below is provided with an anti-siphon servicing unit that is made of grid dish and elastic rubber fitting; Make that anti-siphon effect of the present utility model is better.
Of the present utility modelly usefully be: shunting disk is connected with water inlet pipe top fit but not welds, and does not have the contraposition problem, assembles more quick; The pod apertures of the shunting disk at water inlet pipe top is by sealing rubber cushion control water inlet or sealing.It is more simple that the gap between shunting disk top, shunting disk side and the gland and the water outlet breach of outlet pipe constitute an exhalant canal structure, during the water inlet pipe cutout, anti-siphon rubber cushion is opened air inlet, and the water of avoiding water tank pollutes through the outlet pipe water supply pipe that flows backwards back.
