Description
Technical field
A kind of rubber gasket is the utility model is related to, belongs to and irrigates flange field of sealing technology.
Background technology
In the water supply pipe net system of low pressure crop field, flange is that pipeline, pipe fitting, valve, instrument and equipment etc. are attached
One of most important, most common form, flange connection should be exactly bolt, flange, rubber sheet gasket connection, and its sealing is
Rubber sheet gasket is extruded by the pretightning force of bolt, makes elastic deformation caused by rubber sheet gasket, fills up bumps small on sealing surface not
Flat gap, medium is set to be more than the pressure difference of sealing surface both sides by the resistance of sealing surface, so as to realize sealing, wherein rubber sheet gasket
It is the core component for realizing sealing.The subject matter of existing rubber sheet gasket is：The external diameter of ordinary rubber pad is less than ring flange
External diameter, it is only end contact between rubber sheet gasket and flange, if in the case of being extruded without external force, rubber blanket can be at itself
Fall down in the presence of gravity, when rubber sheet gasket is installed, because hand can not directly contact rubber sheet gasket, want rubber sheet gasket
It is installed in pipe network system and is not easy exactly very much, during pipeline network construction, often made troubles to construction, delays to apply
Work progress；In addition, water supply network, during the maintaining in later stage, rubber sheet gasket easily comes off, lost, people is safeguarded to pipe network
Member causes certain economic loss while making troubles.
The content of the invention
The purpose of this utility model is：A kind of anti-dropout flange rubber gasket is provided, to solve current rubber blanket
During piece, rubber sheet gasket is installed in pipe network system exactly and is not easy very much, is made troubles to construction, delays construction speed, and
Rubber sheet gasket easily comes off, lost, the problems such as causing economic loss while being made troubles to pipe network attendant.
To solve the above problems, intending using such a anti-dropout flange rubber gasket, include the rubber blanket of annular
Circle, the external diameter of rubber washer are more than the external diameter of flanged ends, and one end of rubber washer is provided with retaining convex rib, rubber washer
Outward flange is the overhead structure set towards end where retaining convex rib, and the other end of rubber washer is provided with multiple seal beads, and
The retaining convex rib, overhead structure and seal bead are the loop configuration coaxial with rubber washer.
In aforementioned rubber sealing gasket, the overhead structure is the loop configuration that section is " L " type, and one end of overhead structure is hung down
Straight one end for being fixed on rubber washer, the other end are perpendicularly oriented to the axis of rubber washer；
In aforementioned rubber sealing gasket, the seal bead shares four, and four seal beads are coaxially disposed, and from inside to outside
Diameter increases successively；
In aforementioned rubber sealing gasket, the retaining convex rib, overhead structure and seal bead and rubber washer are integral type
Structure, and be elastic caoutchouc；
In aforementioned rubber sealing gasket, the retaining convex rib is square-section.
Compared with prior art, one end of the present utility model is provided with overhead structure, the overhead structure can with flange
Groove be used cooperatively, in the groove for just tipping ring flange in, so, effectively avoid sealing gasket from coming off；Other end design
Seal bead can ensure the reliability of sealing well, in addition, being designed with retaining convex rib, when installing elasticity can occur for the convex tendon
Deform and be clamped in the groove of ring flange, ensure the fixation of sealing gasket.The present invention effectively prevent the loss and peace of sealing gasket
Position is set, the program can effectively improve construction speed, save construction cost, be easy to the later maintenance of water supply network to maintain, simultaneously
Promote the reform of flange professional standard.
