Abstract
The utility model discloses a kind of connection seal arrangement for vacuum pipe, comprise and be sleeved on vacuum pipe upper seal support cover successively, seal ring, compress dottle pin and locking nut, sealed socket sleeve comprises and to be integrally formed and center is provided with base and the termination of through hole, base external diameter is greater than termination external diameter and the two joint caves inward and is formed with annular groove, through hole internal diameter and the vacuum pipe external diameter of base adapt, termination through hole internal diameter is slightly larger than the through hole internal diameter of base, seal ring is arranged in termination, locking nut to be coordinated with the outside thread that termination outer wall is formed by the internal thread that is formed at its inside and is fixed on termination, the compression dottle pin one end be arranged in locking nut is press-fitted to on seal ring, the other end is press-fitted on locking nut inwall by the protruding structure of adjacent end.This connection sealing device structure being used for vacuum pipe is simple, easy to operate, by the interaction between each parts, can be docked by two vacuum pipes fast, and good sealing effect.
Description
Technical field
The utility model relates to seal arrangement field, particularly a kind of connection seal arrangement for vacuum pipe.
Background technique
Traditional vacuum pipe connects and generally adopts welding manner, and this Placement by the restriction of site environment factor, and needs the welder with corresponding technical ability, time-consuming, operation easier large, repairing inconvenient; In addition due to the differentia influence by field condition, welding quality and appearance quality are difficult to reach satisfied result, thus affect construction quality and repairing progress, and the dust polluting environment of Site Welding generation simultaneously, seldom adopts at engineering first-aid repair.
Prior art adopts more seal ring as sealing for tubing joints system, seal ring is inserted in the end of two ends connecting tube, external application two semi-circular tube cards are fastened by bolts, realize pipeline to connect, seal ring sealing surface is applied directly in outer diameter tube, and the structural type of seal ring and Material selec-tion mate unreasonable with operating condition design, directly impact can connect sealing effect, and under elevated pressures effect, may be pulled out, affect construction quality.
Summary of the invention
The purpose of this utility model is to provide that a kind of structure is simple, good sealing effect, can fast by the connection seal arrangement being used for vacuum pipe of two vacuum pipes one connection.
For this reason, the technical solution of the utility model is as follows:
A kind of connection seal arrangement for vacuum pipe, comprise and be sleeved on vacuum pipe upper seal support cover successively, seal ring, compress dottle pin and locking nut, described sealed socket sleeve comprises and to be integrally formed and center is provided with base and the termination of through hole, described base external diameter is greater than described termination external diameter and the two joint caves inward and is formed with annular groove, through hole internal diameter and the vacuum pipe external diameter of described base adapt, described termination through hole internal diameter is slightly larger than the through hole internal diameter of described base, described seal ring is arranged in described termination, for being coated on the joint of two vacuum pipes, described locking nut to be coordinated with the outside thread that termination outer wall is formed by the internal thread that is formed at its inside and is fixed on described termination, the described compression dottle pin one end be arranged in described locking nut is press-fitted to on described seal ring, the other end is press-fitted on described locking nut inwall by the protruding structure of adjacent end.
Wherein, described seal ring is viton seal ring.Fluorine rubber can in high temperature less than 200 DEG C work, and after locking, seal ring is subject to locking nut and compresses distortion, and counterseal power becomes large, pipeline road is tightly embraced, working medium is not leaked.
Compared with prior art, this connection sealing device structure being used for vacuum pipe is simple, easy to operate, by the interaction between each parts, can fast by two vacuum pipe docking, and good sealing effect, can work at high temperature 200 DEG C, the working medium in pipeline is not leaked.
Figure of description
Fig. 1 is the structural representation of the connection seal arrangement for vacuum pipe of the present utility model.
Embodiment
Be described in detail below in conjunction with the structure of accompanying drawing to the connection seal arrangement for vacuum pipe of the present utility model.
As shown in Figure 1, this connection seal arrangement being used for vacuum pipe comprise be sleeved on successively vacuum pipe upper seal support cover 1, seal ring 4, compress dottle pin 3 and locking nut 2, described sealed socket sleeve 1 comprises and to be integrally formed and center is provided with base 11 and the termination 12 of through hole, described base 11 external diameter is greater than described termination 12 external diameter and the two joint caves inward and is formed with annular groove, through hole internal diameter and the vacuum pipe external diameter of described base 11 adapt, described termination 12 through hole internal diameter is slightly larger than the through hole internal diameter of described base 11, described seal ring 4 is arranged in described termination 12, for being coated on the joint of two vacuum pipes, described locking nut 2 to be coordinated with the outside thread that termination 12 outer wall is formed by the internal thread that is formed at its inside and is fixed on described termination 12, described compression dottle pin 3 one end be arranged in described locking nut 2 is press-fitted to on described seal ring 4, the other end is press-fitted on described locking nut 2 inwall by the protruding structure of adjacent end.Wherein, described seal ring 4 is viton seal ring.
