Description

A flange leak detector

technical field

The utility model relates to a leakage detection device, in particular to a flange leakage detector which detects the leakage of a liquid medium and prevents it from splashing around when it leaks.

Background technique

At present, various types of valves are widely used in many industries, especially in petrochemical systems, where one piece of equipment often uses thousands of valves of various types. The installation and connection methods of different valves are different. Among them, the flange connection has the advantages of simple installation and convenient replacement, and is widely used; but the flange connection often has the situation that the bolts are not screwed in place during installation, or the gasket is damaged. , will cause leakage at the connection part of the flange, resulting in the leakage of the medium stored in the equipment, and the slight leakage is not easy to be found at ordinary times, and it is easy to cause waste of resources and pollute the environment; when the leakage is serious, the stored medium may even splash around. Most of the chemical substances have physical and chemical properties that can cause harm to the human body. If they are contaminated with the human body, they will cause harm and pose a safety hazard.

Contents of the invention

The purpose of the utility model is to overcome the deficiencies in the prior art and provide a flange leakage detector with simple and reasonable structure, which will not splash around when the medium leaks and can be recovered. The equipment using this detector is cost-effective and safe. reliable.

According to the technical solution provided by the utility model, the flange leakage detector includes an upper clamp, a lower clamp, a diversion tube and a clamp, the upper clamp is a large semi-circular ring, and the lower clamp is a small semi-circular ring. The arc length of the lower hoop is longer than the notch arc length of the upper hoop, the upper hoop is installed on the outer circle of the flange, the lower hoop is pressed on the upper hoop, the lower hoop overlaps with the side of the upper hoop, and passes through The hoop is pressed tightly, the bottom of the lower hoop is provided with a diversion hole penetrating through the wall of the lower hoop, and the outer wall of the lower hoop is fixed with a diversion tube communicating with the diversion hole.

As a further improvement of the utility model, the upper clamp, the lower clamp, the draft tube and the clamp are all made of stainless steel.

The structure of the utility model is simple and reasonable. Compared with the prior art, when the medium leaks, it will flow out along the upper and lower clamps through the guide tube without splashing everywhere, which is safe and reliable; It can be collected in containers to prevent it from flowing to the ground, causing waste of resources and polluting the environment, and saving costs.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Fig. 2 is a schematic diagram of the specific application of the utility model.

Detailed ways

Below in conjunction with specific accompanying drawing and embodiment the utility model is further described.

As shown in Figure 1, the utility model is mainly assembled by an upper clamp 1, a lower clamp 2, a diversion tube 3 and a clamp 5, the upper clamp 1 is a large semi-circular ring, and the lower clamp 2 is a small Semi-circular ring, the arc length of the lower clamp 2 is longer than the notch arc length of the upper clamp 1, the upper clamp 1 is installed on the outer circle of the flange 6, the lower clamp 2 is pressed on the upper clamp 1, and their sides overlap , and pressed by the hoop 5, the bottom of the lower hoop 2 is provided with a diversion hole 4 passing through the wall of the lower hoop 2, and the outer wall of the lower hoop 2 is welded and fixed with a diversion tube 3 communicating with the diversion hole 4. When the medium leaks, it will flow out along the upper and lower clamps 1 and 2 through the guide tube 3, without splashing around; the outflowing medium can be collected in a pre-installed container to prevent it from flowing to the ground, causing waste of resources and polluting the environment , saving costs; regular inspection of pre-installed containers can easily understand the sealing condition of storage equipment, and when the medium leaks slightly, it can be found and appropriate treatment measures can be taken to prevent further expansion of losses.

In addition, in order to further improve the corrosion resistance of the device and prolong its service life, the upper clamp 1, the lower clamp 2, the draft tube 3 and the clamp 5 are all made of stainless steel.
