Abstract

The utility model provides a top pressure injection fixture, which includes a fixture body, a pressure plate and a push rod, the push rod is aligned with the positioning round hole of the pressure plate, the shape of the pressure plate fits the shape of the leakage of the fixture body, and an injection hole is arranged in the middle of the pressure plate. The beneficial effects of the utility model are: the utility model is suitable for leakage points with low temperature and low pressure. Due to the adjustability of the pressure plate, the construction is relatively flexible, which brings a large adjustment space to the construction personnel and improves the plugging capacity. success rate.

Description

Top pressure injection fixture

technical field

The utility model belongs to the field of plugging and repairing appliances, in particular to a top pressure injection fixture.

Background technique

During the transportation and storage of liquids in pipelines, due to long-term use and external objective influences such as wind and weather, there will be problems of damage and leakage, especially when transporting and storing highly corrosive liquids, leakage problems often occur . At present, the treatment method after pipeline leakage is generally to stop production, remove the liquid, perform repair welding and other operations, and then start it after passing the acceptance. The shutdown will seriously affect the production progress, cause huge economic losses, and pollute the environment. In the later stage, a huge amount of pollution needs to be invested Governance fees. The seal of the flange is damaged during production, and it needs to be repaired in time. In the existing technology, it is mainly aimed at different leakage points of the flange, and different plugging fixtures and methods are selected according to different leakage conditions. Design 1. Making plugging jigs of different specifications has technical problems such as not being universal and not being able to mend leaks in time.

Contents of the invention

The purpose of the utility model is to provide a top pressure injection fixture with simple structure, strong adjustability and convenient operation.

The technical solution of the utility model is: the top pressure injection fixture includes a fixture body, a pressure plate and a push rod, the push rod is aligned with the positioning round hole of the pressure plate, and the shape of the pressure plate fits the shape of the leakage of the fixture body, An injection hole is arranged in the middle of the pressing plate.

The diameter of the injection hole is 4mm.

The advantages and positive effects of the utility model are: the utility model is suitable for leakage points with low temperature and low pressure. Due to the adjustability of the pressure plate, the construction is relatively flexible, which brings a large adjustment space to the construction personnel and improves The success rate of plugging.

Detailed ways

As shown in Figure 1, the top pressure injection fixture of the utility model includes a fixture body 1, a pressure plate 2 and a push rod 3, the push rod 3 is aligned with the positioning round hole of the pressure plate 2, and the shape of the pressure plate 2 fits the leakage of the fixture body 1. The shape of the center, the injection hole 4 is set in the middle of the pressure plate 2.

The working process of this example: Take the flange as an example, make an arc-shaped pressure plate 2 with a width equal to the gap between the flanges, drill a 4mm injection hole 4 in the middle, quickly depress the pressure plate 2, and tighten the ejector rod 3 to form a sealed cavity. Rod 3 injects sealant 5 into the leakage point to achieve sealing specific pressure and eliminate leakage.

An embodiment of the present utility model has been described in detail above, but the content described is only a preferred embodiment of the present utility model, and cannot be considered as limiting the implementation scope of the present utility model. All equal changes and improvements made according to the application scope of the utility model should still belong to the scope covered by the patent of the utility model.
