Description

Technical Field

[0001] The utility model belongs to the technical field of thermal insulation pipes, and in particular relates to a prefabricated thermal insulation pipe glue injection and sealing mechanism. Background Art

[0002] Prefabricated direct buried insulation pipe is composed of steel pipe (working pipe) for conveying medium, polyurethane rigid foam plastic layer (insulation layer), high-density polyethylene outer sleeve (outer protective layer). It is widely used in insulation and cold preservation projects of central heating pipelines, central air-conditioning pipelines, chemical, pharmaceutical and other industrial pipelines due to its advantages of low heat loss, good corrosion resistance and insulation performance, fast and safe construction, etc. The main process is to spray polyurethane on the surface of the rust-removed steel pipe, and then insert the external protection pipe on the outside of the steel pipe, and then inject the insulation material foaming liquid into the gap between the steel pipe and the external protection pipe to complete the production of the insulation pipe. In the process of injecting the foaming liquid between the steel pipe and the external protection pipe, it is necessary to seal the two with sealing rings at both ends, otherwise the foaming liquid will leak out directly from both sides. The sealing ring structure currently used by the company is too complicated, and assembly and disassembly are very time-consuming and labor-intensive, so it is urgent to improve this sealing ring.

[0017] In the description of the present disclosure, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, it can be a mechanical connection, an electrical connection, or a communication connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0018] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings and preferred embodiments.

[0019] like Figure 1 and Figure 2 As shown, the utility model discloses a prefabricated thermal insulation pipe glue injection plugging mechanism, including a sealing ring 1 and a plurality of adjusting mechanisms 2. In order to ensure sealing, the sealing ring has an inclined surface around the circumference. The adjusting mechanism is used to drive the sealing ring to move between the steel pipe and the external protective pipe. In this device, there are four adjusting mechanisms, which are evenly distributed around the sealing ring.

[0020] Specifically, the adjustment mechanism includes an adjustment block 3, a clamping bolt 4 and a long clamping bolt 5. One side of the adjustment block is provided with a C-shaped opening 6. The clamping bolt is threadedly connected to one side of the C-shaped opening. The C-shaped opening is used to clamp the end of the steel pipe and is fixed by the clamping bolt. The long clamping bolt passes through the adjustment block and is threadedly connected to the inner part of the steel pipe. One end of the long clamping bolt cooperates with one side of the sealing ring. The axial direction of the long clamping bolt is perpendicular to the axial direction of the clamping bolt. When the adjustment block is fixed to the steel pipe by the clamping bolt, the long clamping bolt moves in the adjustment block by turning the long clamping bolt, thereby driving the sealing ring to move and controlling the distance between the sealing ring and the outer protective tube.

[0021] Furthermore, in order to facilitate the connection between the sealing ring and the clamping long bolt, a positioning block 7 is fixed to the side of the sealing ring, and one end of the clamping long bolt is rotatably matched with the positioning block. The movement of the clamping long bolt drives the positioning block to follow the movement. Specifically, a strip groove 8 is opened on the inner side of the positioning block, and a circular groove 9 is provided at the end of the strip groove. An end cap 10 is provided at one end of the clamping long bolt, and the end cap is inserted from the strip groove into the circular groove. The clamping long bolt can rotate in the positioning block and can also drive the positioning block to move.

[0022] When in use, place the sealing ring between the steel pipe 11 and the external protective tube 12, and then insert the C-shaped opening of the adjusting block into the outside of the steel pipe. This device adopts four adjusting blocks. The position of the adjusting block is adjusted so that the end cap at the end of the tightening long bolt enters the positioning block on the side of the sealing ring. After the positions are determined, tighten the clamping bolt to fix the adjusting block on the steel pipe, and finally turn the tightening long bolt to adjust the depth of the sealing ring in the steel pipe and the external protective tube. After sealing, glue injection can be completed. After glue injection is completed, turn the tightening long bolt in the opposite direction to pull the sealing ring out from between the steel pipe and the external protective tube, and finally remove the adjusting block. This device is very convenient to install and disassemble.

[0023] It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications should also be regarded as the protection scope of the utility model.
