Sealing device with function of quick locking

Abstract

The invention discloses a sealing device with a function of quick locking. The sealing device comprises a body base, an oil pipe penetrating through the body base, and an O-shaped ring which is arranged on the outer end face of a flange of the body base. The sealing device is characterized in that a symmetric rotation clamping device and a compression sealing device are arranged on the body base.In the design, the clamping technology that wedge surfaces compress pin shafts, the pin shafts transfer force to clamping blocks, and the clamping blocks are centered to tightly hold a pipe piece is adopted, and the integrated cone-sleeve cooperation sealing technology that the sealing ring is axially compressed is adopted. The device has no requirements for a special structure of a steel pipe piece connection end, the device is easy to assembly, install and operate, the structure is compact and smart, the cost is low, the practicability is high, and the device can be reused.

Description

technical field [0001] The invention relates to a sealing device, in particular to a combined quick clamping sealing device. Background technique [0002] In the actual operation of water, oil, and gas steel pipelines that need to be sealed and connected, there is a lack of a convenient and fast fast sealing and connecting device; after searching, it is known that the technical solutions of the following two patents are relatively close to the technology of the present invention , 1 is: CN205424190U-a flanged pipe fitting pipeline sealing device; 2 is: CN106641534A-quick connector. Both of these two patented technologies have made certain contributions to solving the tube sealing and detachable technology, and also proposed corresponding feasible technical solutions. But, as the combined technical scheme of the wedge-shaped block quickly clamping the oil pipe and the tapered sleeve pressing and sealing, the above two technical schemes have not been proposed. First of all, ...

Problems solved by technology

However, as a combined technical scheme of the integrated wedge block quickly clamping the oil pipe and the taper sleeve pressing and sealing, the above two technical schemes have not been proposed.

First of all, patent 1 clamps and seals the pipe through the snap ring and the snap teeth, which puts forward requirements on the shape of the joint part of the pipe, that is, a snap ring groove for the snap ring is required, so that the flat pipe is relatively flat. The effect of clamping and sealing is not easy to realize, and the connection between the pipeline and the valve plate is not fully described in the technical solution of this patent; secondly, patent 2 adopts the clamping and sealing device of sliding mode, which is also for the The requirements for the joints of pipe fittings are put forward, which is suitable for connecting external spigot-type structural parts. At the same time, when the diameter of the pipeline is large, the processing of the snap ring and the sleeve of the patented structure is relatively difficult, and it is also difficult to push the snap-fit ​​seal. accomplish
