Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, and in particular to a device for detecting the sealing performance of a drainer's observation port. Background Technology

[0002] A gas drainer is a device used to remove moisture and impurities from gas pipelines. Firstly, the gas drainer utilizes the principle of physical separation, changing the flow rate and direction of the gas flow to separate moisture and impurities from the gas. Since the gas drainer needs to be checked regularly, a funnel-shaped drain pipe is installed at the outlet of the drainer to facilitate the inspection of its operation.

[0003] Due to increasingly stringent environmental protection requirements and the construction of green factories in recent years, the open discharge of gas drain pipes can cause environmental pollution. Furthermore, there is a risk of gas leaks and poisoning during on-site inspections. Therefore, it is necessary to seal the observation port of the drain pipe. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a device for detecting the sealing performance of the observation port of a drainer, which overcomes the shortcomings of the prior art and effectively solves the problems of environmental pollution and personnel poisoning caused by open discharge of gas drainers.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A device for testing the sealing performance of a drainer's observation port includes a horizontal pipe. Side flanges are welded to the outer walls of both ends of the horizontal pipe, and an inspection flange is provided on one side of the outer wall of the side flange. An inspection lens is placed on one side of the inner wall of the inspection flange, and a retaining ring is provided on one side of the inspection lens.

[0007] Symmetrically distributed outer sleeves are welded to one side of the outer wall of the horizontal tube, and a sealed bearing is installed on the inner wall of the outer sleeve. A cleaning tube is fixedly connected to the inner ring of the sealed bearing. A nozzle is installed on the outer wall of one end of the cleaning tube, and a valve is installed on the end of the outer wall of the cleaning tube away from the nozzle.

[0008] Preferably, the side flange and the inspection flange are fixedly connected by equally spaced fastening bolts.

[0009] Preferably, the inner wall of one side of the inspection flange is provided with an installation groove, and the retaining ring is welded to the inner wall of the installation groove.

[0010] Preferably, a drain pipe is welded to the top of the outer wall of the horizontal pipe, and an upper flange is installed on the top outer wall of the drain pipe.

[0011] Preferably, a flared variable diameter bucket is welded to the bottom of the outer wall of the horizontal tube, and a drain pipe is welded to the bottom outer wall of the flared variable diameter bucket.

[0012] Preferably, a lower flange is welded to the outer wall at the bottom of the drain pipe.

[0013] Preferably, the centers of the nozzle and the horizontal pipe are on the same axis.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. The drainage outlet sealing test device designed in this paper allows on-site inspectors to check the operation of the drainage device through the sight glass without affecting production. By improving the drainage pipe sight glass, the drainage outlet of the drainage device is sealed, solving the problem of odor diffusion from the drainage outlet and eliminating the risk of poisoning during drainage device inspection. It can effectively solve the problem of exhaust gas discharge without affecting the inspection of the drainage device.
