Abstract
The utility model discloses a kind of sealing element of bulb tube connector, gasket including circular ring shape, the edge of the gasket is equipped with flange outwardly, flange and gasket form step, are connected between flange and gasket by inclined surface, and the thickness of flange is less than the thickness of gasket, flange is attached between pipe fitting, flange and gasket form step, and sealing element is not easy to be moved position, and ensure that the concentricity of sealing element and pipe fitting.
Description
Technical field
The utility model relates to a kind of gasket seal, in particular to a kind of sealing element of bulb tube connector.
Background technique
In some equipment for needing to use high temperature high voltage resistant pipeline, and for the reliability of pipe joint, generally pipeline
Connector is designed to the spherical surface of male-female engagement, the sealing element installed on bulb tube connector currently on the market, generally rubber material
Gasket, which is generally circular ring shape, has the following problems in the process of installation: when installation, 1: since general pipeline is in sleeping
Formula state, the bad positioning of sealing element, be easy dress causes pore part to be blocked partially；2, rubber sheet gasket is easily deformed, and is easy quilt
The gas or liquid of high temperature and pressure squeeze out and lead to seal failure.
Utility model content
The shortcomings that the purpose of the utility model is to overcome the prior arts and deficiency provide a kind of for having spherical surface interface
Pipeline on sealing element, the sealing element can in conjunction with spherical male and fomale(M&F), preferably position, it is not easy to deform.
The purpose of this utility model is achieved through the following technical solutions: a kind of sealing element of bulb tube connector, including annulus
The gasket of shape, the edge of the gasket are equipped with flange outwardly, and flange and gasket form step, by inclining between flange and gasket
Inclined-plane connection, the thickness of flange are less than the thickness of gasket.
Preferably, the gasket and flange are an integral molding structure.
Preferably, the sealing element is made of polytetrafluoroethylene (PTFE).
Preferably, the angle between the flange and inclined surface is 135 degree.
Preferably, the outermost of the flange is additionally provided with inflection side, and the inflection side is vertical with flange.
The utility model is compared with the existing technology have following advantages and effects portion between spherical surface and pipe fitting outer rim
With after Hp contacts, flange can tightly touch two pipe fittings for position, realize the perfect positioning of sealing element, guarantee sealing element and pipe
The concentricity of connector can prevent sealing element dress from causing pore part to be blocked partially, and flange is attached to the spherical surface and pipe of evagination
Between connector on position, flange and gasket form step, and sealing element is not easy to be moved position.
Detailed description of the invention
Fig. 1 is the front view of the sealing element of bulb tube connector.
Fig. 2 is the sealing element of bulb tube connector and the combination figure on inflection side.
Fig. 3 is installation diagram of the sealing element of bulb tube connector in pipe fitting.
Specific embodiment
The present invention will be further described in detail with reference to the embodiments and the accompanying drawings, but the implementation of the utility model
Mode is without being limited thereto.
- Fig. 3 referring to Fig.1, the sealing element of the bulb tube connector, the gasket 1 including circular ring shape, the edge of the gasket 1
Equipped with flange 3 outwardly, flange 3 and gasket 1 form step, are connected between flange 3 and gasket 1 by inclined surface 2, flange 3
Thickness is less than the thickness of gasket 1, when in use: when installation, first 3 position of flange of sealing element can be made to be directed at pipe fitting with hand
5 outer circles, the spherical of evagination enter inside pipe fitting 5, the location contacts in pipe fitting 5, between 5 outer rim of spherical surface and pipe fitting
After can preferably position, can prevent sealing element dress from causing pore part to be blocked partially, and flange 3 be attached to the spherical surface of evagination with
Between pipe fitting 5 on position, flange 3 and gasket 1 form step, it is not easy to be moved position.First make the convex of sealing element with hand
1 position of edge is directed at the outer circle of the recessed spherical surface of another pipe fitting 6, and the spherical of evagination enters in recessed spherical surface, and two pipes connect
Head compresses sealing element, and collar nut 7 and the external screw thread of pipe fitting 6 are screwed, so that the spherical of evagination and recessed spherical surface pressure
Tight seal is to play sealing.
As preferential embodiment, the gasket 1 and flange 3 are an integral molding structure.In preferred scheme, sealing
Part is made of polytetrafluoroethylene (PTFE), using the polytetrafluoroethylene material for having some strength and stable chemical performance, sealing element be not easy by
The gas or liquid of high temperature and pressure squeeze out and lead to seal failure.
As preferential embodiment, angle between the flange 3 and inclined surface 2 is 135 degree, so as to tightly
Touch outer recessed spherical surface and recessed spherical surface.
As preferential embodiment, the outermost of the flange 3 is additionally provided with inflection side 4, the inflection side 4 and flange 3
Vertically, before the mounting, inflection side 4 can be stuck in the outer surface of pipe fitting 5, it is ensured that gasket 1 cannot move, and lead at this time
Cross the make-up of nut 7, it is ensured that the concentricity of sealing element and pipe fitting.
Above-described embodiment is the preferable embodiment of the utility model, but the embodiments of the present invention is not by above-mentioned
The limitation of embodiment, it is made under other any spiritual essence and principles without departing from the utility model to change, modify, replacing
In generation, simplifies combination, should be equivalent substitute mode, is included within the protection scope of the utility model.
