Abstract
The utility model relates to a sealing pad which is used for a hydraulic pipe fitting, particularly a sealing gasket being suitable for a membrane pipe connecting piece arranged on a membrane separating device in the production of chloropropene. The external shape forms a round table shape, the middle is provided with an inner hole which is provided with a step, the contact surfaces 2, 3 of the sealing pad and a pipe fitting are in tight fit under the pressurization of a nut arranged in a pipe joint, contact surface 1 and a membrane pipe are simultaneously in tight fit, and the fluid of the inner and the outer sides of the membrane pipe can not leak. The utility model has the characteristics of simple structure, easy fabrication, easy installation, aging resistance, corrosion resistance, and long service life.
Description
Technical field
The utility model relates to a kind of sealing gasket of chemical industry hydraulic tube piece, is particularly useful for chloroacrylate and produces the sealing gasket that the film pipe connects on the membrane separation device.
Background technique
Therefore in the membrane separation device, will circulate in the pipeline acidity or corrosive liquids require the sealing material at film pipe two must possess performances such as antiacid, alkali resistant, anticorrosive, tight seal.
The sealing gasket (as Fig. 1) that use existing membrane separation device periosteum joint adopts rubber to make, on sealing gasket, have a circular groove 6, metal supporting rings (as Fig. 2) is installed in circular groove 6, in use, by the pressuring action of metal supporting rings, make the sealing contact surface 4 of sealing gasket, surface of contact 5, surface of contact 7 closely cooperates with pipe fitting joint, plays the effect of sealing.But this gasket structure, install complicatedly, the back easy deformation is installed, working life is short, will corrosion failure after after a while, cause material from leakage or string mutually.
Summary of the invention
The purpose of this utility model is to overcome the defective in the present technology, provides a kind of simple in structure, easily processing, install simple and easy, the sealing gasket of long service life.
To achieve these goals, the utility model profile is a frustoconic shape, the centre has endoporus, and endoporus has a step, adding of nut, depress in being installed in pipe joint, the surface of contact 2,3 and the pipe fitting of sealing gasket are closely cooperated, and surface of contact 1 closely cooperates with the film pipe simultaneously, makes the fluid of the inside and outside both sides of film pipe seepage can not take place.
The utility model adopts politef material the best, because this material acid resistant alkali, anticorrosive, and hardness is suitable, can excessive deformation after the installation, have excellent sealing performance.
The utility model compare with present technology have simple in structure, easily processing, install simple and easy, ageing-resistant, corrosion-resistant, the characteristics of long service life.Guaranteed stable, the long-term operation of tooling, brought tangible economic benefit to factory.
Description of drawings
Fig. 1 is the sectional view of the sealing gasket that uses in the prior art.
Fig. 2 is the sectional view of the metal supporting rings used in the prior art.
Fig. 3 is the sectional view of the utility model sealing gasket.
Embodiment
The utility model profile adopts the politef material, is frustoconic shape, and the centre has endoporus, and endoporus has a step.During enforcement, depress in adding of pipe joint nut, the surface of contact 2 of sealing gasket, surface of contact 3 are closely cooperated with pipe fitting, surface of contact 1 closely cooperates with the film pipe simultaneously.The utility model simple installation, the installation back operation period is long, and the sealing gasket joint phenomenon of material seepage all do not occur through repeatedly disassembly, cleaning.
Claims (2)
1, a kind of sealing gasket is characterized in that profile is a frustoconic shape, and the centre has endoporus, and endoporus has a step, adding of nut, depress in being installed in pipe joint, and the surface of contact (2) of sealing gasket, surface of contact (3) are closely cooperated with pipe fitting, and surface of contact (1) closely cooperates with the film pipe simultaneously.
2, sealing gasket according to claim 1 is characterized in that: adopt the politef material to make.
