The anti-leak gas drainage device relates to a gas pipeline drainage system produced and used by industrial enterprises. It is specifically suitable for water-sealed drainage devices with large displacement of gas pipelines, good energy-saving effect and strong secondary leakage prevention function. Then, let's learn about the production process of the anti-leak gas drainage device!

Leak-proof gas drainers are suitable for water-sealed drainers of well-known gas transportation pipelines. There are two types of water-sealed drainers: ordinary water-sealed drainers and ordinary leak-proof water-sealed drainers. The general water seal drain has a simple structure, but it needs long-term water replenishment to maintain overflow and waste energy. In addition, when the downpipe in the water seal is eroded and damaged, the water seal is damaged due to insufficient height, causing a large amount of gas outflow accident. Although it is shown that the general leak-proof water seal drain has leak-proof and water-saving functions, there are two disadvantages:

First, when the anti-leakage function works, it is necessary to restore the function of maintaining the drainage after the gas is discharged through the drainage outlet, which cannot completely eliminate the defect that personnel may cause poisoning due to gas contact.

Second, the amount of accumulated water in the gas pipeline increases sharply, and the leak-proof function will also start and stop drainage. In other words, due to the defect that it is impossible to accurately identify whether it is damaged by air pressure or the water volume increases, the effective drainage and safe operation of the gas pipeline are seriously affected.

In order to solve the shortcomings of traditional water-sealed drainers, the utility model provides a simple structure, the larger the water volume, the larger the displacement, the two-stage anti-leakage function, and the energy-saving two-stage anti-leakage drainage without manual recovery. Water seal drain.

In order to solve the technical problems of the leak-proof gas drainage device, decontamination holes are arranged at the lower part of the water sealing box and the water sealing box, the outer wheel of the decontamination hole is arranged on the decontamination hole, one fastening bolt is arranged on both sides of the outer wheel of the decontamination hole, and the fastening plate is arranged on one side of the fastening plate with a locking nut and a fastening screw in the middle of the fastening plate, the water sealing box with fastening rotating rod for cleaning outside the screw has a downpipe inserted from top to bottom. The downpipe is equipped with a water washing cleaning pipe at the exposed part of the water sealing box, and a ball valve and a screw plug are installed on the water washing cleaning pipe. A leakage prevention float is installed on the upper part of the water sealing box. There are an upper positioning slider and a lower positioning slider on both sides of the leakage prevention float, and the other upper positioning slider and the other lower positioning slider. A positioning frame and another positioning frame are also provided at both ends of the leakage prevention float, and a sliding groove and another sliding groove are respectively provided on the positioning frame and the other positioning frame. One upper positioning slider and one lower positioning slider are fitted with one chute, and the other upper positioning slider and the other lower positioning slider are fitted with another chute. Below the center of the leak-proof float are: groove-type rubber head, connecting chain, blocking plate, secondary blocking of drain pipe and primary blocking of drain pipe. The lower center of the leak-proof float is equipped with fixing bolts, bolt rods and bolt rods fixing groove-type rubber heads, the primary closing opening of the chain drain pipe connected below the bolt rod is connected with the drain pipe protruding to the outside of the water seal housing, and the outside of the drain pipe is provided with a capped cleaning pipe; The upper part of the center of the anti-leakage float is provided with a fixing rod, which is provided with a lower garden splint, a rubber pad and an upper garden splint, and is installed in the sealing tube on the upper surface of the top cover of the water seal box.

The upper part of the sealing pipe is connected with the release pipe, between which the top plate of the sealing pipe is arranged, and the top plate of the sealing pipe is provided with ventilation holes. Patent Document 1 discloses a drainage energy-saving device. The decontamination hole, the outer ring of the decontamination hole and the fastening bolts and fastening plates on both sides are provided at the lower part of the water sealing box and the water sealing box. The fastening plate is provided with a clamping groove, a locking nut, a fastening screw and a rotating rod are arranged in the middle of the fastening plate, and a sealing cover is arranged between the decontamination hole and the fastening plate, water washing cleaning pipe, ball valve and plug wire are installed on the chute. Anti-leakage float is installed in the water seal box. Both sides of the anti-leakage float are provided with upper and lower positioning sliding blocks. Both ends of the anti-leakage float are respectively provided with chute. The lower part of the anti-leakage float is provided with groove-type rubber head, secondary plugging of drain pipe, blocking plate and primary plugging of drain pipe. Capping pipe is provided on the outside; the upper part of the anti-leakage float is connected with a clamp, a bottom plate, a fixing rod with a rubber sealing ring, a sealing pipe above the top cover of the water sealing tank, and a heat pipe above the sealing pipe.

The above is the production process of the leak-proof gas drain. If you need to know more, please feel free to contact us!
