Problems solved by technology

[0002] At present, various pipeline systems such as: gas pipelines, water supply pipelines, oil pipelines, etc. are widely used in people's daily life. Pipeline deflection and thermal expansion and contraction caused by complex terrain, seasonal changes, and large temperature differences between day and night will have a serious impact on the pipeline. The general solution is to set compensation joints during the pipeline laying process to compensate for the axis of the pipeline However, this will cause leakage due to poor sealing of the pipe joints, which may cause a large safety accident. Therefore, the requirements for its sealing and reliability are extremely high. Traditional pipe joints generally have complex structures. The disadvantages of poor sealing effect and low safety and reliability

Embodiment Construction

[0014] Please refer to figure 1 as shown, figure 1 It is a schematic diagram of the structure of the stuffing box type compensation joint of the present invention. In this embodiment, a stuffing box type compensation joint includes a body 1 and a telescopic tube 2 sleeved in the body 1. The outer circle of the telescopic tube 2 and the A gland 3 is arranged between the body 1, the gland 3, the outer circle of the telescopic tube 2 and the body 1 form a stuffing box 4, and bushings 5 ​​are arranged at both ends of the stuffing box 4, and the bushing 5 Rubber sealing rings 6 and graphite packing layers 7 are arranged at intervals, and fixing bolts 8 are pierced between the gland 3 and the body 1 , and fixing nuts 9 are arranged in cooperation with the fixing bolts 8 .

[0015] The stuffing box type compensation joint is connected to the stuffing box 4 formed by the body 1, the gland 3 and the outer circle of the telescopic tube 2. The stuffing box 4 is provided with a rubber se...

Abstract

The invention discloses a stuffing box type compensating joint comprising a body and an extension tube sheathed in the body, wherein a gland is arranged between the excircle of the extension tube and the body, and the gland, the excircle of the extension tube and the body form the stuffing box; two ends of the stuffing box are both provided with bushes, and rubber seal rings and graphite packing layers are arranged at intervals between the bushes; a fixing bolt penetrates through the space between the gland and the body, and a fixing nut is arranged by being cooperated with the fixing bolt; the stuffing box type compensating joint causes the gland to press the seal ring by screwing bolts and nuts, so that the seal ring generates elastic deformation to extrude the body and the extension tube to achieve the purpose of sealing. Thus, the invention ensures that the extension tube slides relatively to the body without leaking, and has simple structure, good sealing effect and high safe reliability.

Description

technical field [0001] The invention relates to a pipe joint, in particular to a stuffing box type compensation joint with good sealing effect. Background technique [0002] At present, various pipeline systems such as: gas pipelines, water supply pipelines, oil pipelines, etc. are widely used in people's daily life. Pipeline deflection and thermal expansion and contraction caused by complex terrain, seasonal changes, and large temperature differences between day and night will have a serious impact on the pipeline. The general solution is to set compensation joints during the pipeline laying process to compensate for the axis of the pipeline However, this will cause leakage due to poor sealing of the pipe joints, which may cause a large safety accident. Therefore, the requirements for its sealing and reliability are extremely high. Traditional pipe joints generally have complex structures. The shortcomings of poor sealing effect and low safety and reliability. Contents o...
