Description
Technical field
The present invention relates to tap, specially a kind of anti-loosening free bonding tap with membrance.
Background technology
Existing tap with membrance, reference picture 1, it includes valve body 1, diaphragm of rubber 2, moulding circle 3, gland 4, lifting screw
6th, spacing ring 7 and spiral cover 5；The valve body 1 has intake antrum 1-1, water chamber 1-2 and the faucet connected with water chamber 1-2,
The mouth that dams is provided between intake antrum 1-1 and water chamber 1-2, mouthful upper end of damming is matched somebody with somebody provided with diaphragm of rubber step 1-3, step 1-3
Fill diaphragm of rubber 2, lifting screw 6 is located in moulding circle 3 and matched, and moulding circle 3 matches with valve body 1 to be equipped with, and is compressed
Diaphragm of rubber 2, gland 4 are threadedly coupled fixed moulding circle 3 with valve body 1, spacing ring 7 are arranged on the valve body 1 below gland 4（It is logical
The blue ring that custom is said）, the inwall of spiral cover 5 is adapted with the external screw thread of spacing ring 7 provided with internal thread, is additionally provided with and lifts in spiral cover 5
The threaded connector that screw rod 6 matches, spiral cover 5 are limited during rotation by spacing ring 7, and spiral cover 5 does not move up and down,
Drive lifting screw 6 up and down by spiral cover 5.Spiral cover 5 is threadedly connected with lifting screw 6, and the time is grown, spiral cover 5
It can release automatically.Meanwhile when spiral cover 5 drives lifting screw 6 to rotate, between spiral cover 5 and spacing ring 7, spiral cover 5 and gland 4 all
There is Relative friction motion, because gland 4 does not prevent its measure rotated, if rotating freely, gland 4 will loosen, and lead
Cause moulding circle 3 to loosen, and then loosen diaphragm of rubber 2, leak occurs.In order to prevent spiral cover 5 and spacing ring 7, gland 4 and valve body
Loosening is produced between 1, between gland 4 and valve body 1, spacing ring 7 and spiral cover 5, is bonded with bonding agent, otherwise, can all loosened
Come off.Time is grown, bonding agent also can aging, reliability decrease.In addition, using bonding agent, pollution can be produced to environment.
The content of the invention
The purpose of the present invention is that in view of the shortcomings of the prior art, the structure of existing tap with membrance is improved,
It is reasonable in design to provide one kind, it is simple in construction, do not loosen, without the tap with membrance of bonding agent.
Realizing the technical scheme of the object of the invention is：
A kind of anti-loosening free bonding tap with membrance, including valve body, diaphragm of rubber, moulding circle, gland, lifting screw and rotation
Lid；The valve body has intake antrum, water chamber and the faucet connected with water chamber, is provided between intake antrum and water chamber
Dam mouth, and mouthful upper end of damming is provided with diaphragm of rubber step, step fitted with rubber barrier film, unlike the prior art：
The inwall of the moulding circle is provided with inner trapezoidal thread, and the groove that projection and valve body are provided with the top of the outer wall of moulding circle is embedded in,
Fixed moulding circle prevents it from loosening；
The bottom of the lifting screw is hollow cylindrical, and cylindrical outer wall is provided with the interior trapezoidal spiral shell of outer trapezoidal thread and moulding circle
Line is adapted, and the top of lifting screw is non-circular post；The end of the outer trapezoidal thread of lifting screw, can freely up and down without line
Motion, when it rises to setting position, you can voluntarily position and lock；
The inwall of the gland is adapted provided with internal thread with the external screw thread on valve body, and is fixed moulding circle；
The shrinkage pool being adapted with the non-circular post on lifting screw top is provided with the spiral cover, lifting screw and spiral cover pass through not rounded
Shape post is fixedly connected with shrinkage pool matching, drives lifting screw to move up and down when spiral cover rotates；
The lifting screw is located in moulding circle and matched, and moulding circle matches with valve body is equipped with and compresses diaphragm of rubber,
Gland is connected through a screw thread with valve body and fixes moulding circle, and spiral cover is set in outside gland and is connected with lifting screw.
The center of the diaphragm of rubber is provided with projection, is additionally provided with the compression leg to match with projection, and the top of compression leg is inlaid in
In the hollow cylindrical of lifting screw.
During the tap assembling, by diaphragm of rubber on its step, and the projection of compression leg and diaphragm of rubber is equipped with,
Lifting screw is equipped with moulding circle, and moulding circle is equipped with valve body, then gland is connected with valve body, and spiral cover finally is set in into gland
It is connected outside and with lifting screw.
Tap with membrance of the present invention, lifting screw are connected through a screw thread with moulding circle, and are fixed by gland
Cushion rubber, spiral cover is interior to be provided with the shrinkage pool being adapted with the non-circular post on lifting screw top, and spiral cover rotation drives lifting screw simultaneously
Move up and down；Compression leg is provided between diaphragm of rubber and lifting screw, on the one hand compression leg is fixed to diaphragm of rubber, separately
On the one hand avoid lifting screw from directly being contacted with diaphragm of rubber, avoid lifting screw from being produced when rotating with diaphragm of rubber and rub, shadow
Ring the service life of diaphragm of rubber.In addition, when spiral cover drives lifting screw motion, spiral cover and gland, gland and valve body, compression
Between circle and valve body, friction is not produced, and is completely embedded, and will not be loosened, it is not necessary to using bonding agent, while eliminate spacing ring
Part.
Tap with membrance of the present invention：Simple in construction, reasonable in design, dismounting is convenient, easy to use, cost-effective, also has
There is the characteristics of anti-loosening, free bonding.
