Abstract

The utility model belongs to industry gas-phase medium cutoff technology field, principally relates to an U-shaped tube-type water-sealed tank. A tank (2) of the water-sealed tank has an U-shaped structure, the top of the tank (2) is provided with an inlet duct (1) and an outlet duct (5), the lower end of the tank is provided with a port (3) for charging and discharging water, and the upper part of the tank nearby the outlet duct is provided with an overflow port (4). According to the utility model, because gas-phase pipes have non right angles, local resistance coefficient is reduced greatly compared with that of traditional water-sealed tank; simultaneously, sectional area of the gas-phase pipe is not changed, such that the structure reduces pressure-drop loss to maximum extent.

Description

U type tubular type water sealed tank

Technical field

The utility model belongs to industrial gas phase media stopped flow technique field, relates generally to a kind of U type tubular type water sealed tank.

Background technique

In oil refining, chemical industry field, large-scale low-pressure vapor phase medium is when carrying, and the cutting-off method of pipeline is a lot, and at present, the general method that adopts is the water seal pot process.The water sealed tank that is now adopted is made easily, and cost is low, and is difficult for leaking.But, present employed water sealed tank must be with 90 ° of intercross arrangement of large diameter low-pressure vapor phase pipeline, and make gas phase media when normally carrying by water sealed tank, processes such as enlarging deceleration, dilatation, 180 ° turn to, reducing acceleration have been carried out, cause gas phase media pressure loss the time big normally by water sealed tank, thereby directly influence the transmitting power input or the energy recovery output of gas phase media, increased the loss of energy.

Summary of the invention

The purpose of this utility model is to propose a kind of U type tubular type water sealed tank, make it have advantages such as pressure drop is little, simple in structure, sealing is tight, thereby it is big to solve traditional water sealed cans pressure loss when carrying gas phase media, the problem that energy consumption is many.

The utility model is finished the technological scheme that its invention task taked:

A kind of U type tubular type water sealed tank, the tank body of described water sealed tank is a U type structure, and the top of described tank body has suction tude and steam outlet pipe, and the lower end of tank body has intake-outlet, and on the tank body top of steam outlet pipe one side flow-off is set.

The utility model has adopted technological scheme as mentioned above, has following advantage:

1. pressure drop is low, and promptly the pressure loss of energy is low.

Low pressure loss U-shaped pipe water sealed tank of the present utility model, because the gas phase pipeline does not have the right angle to distribute, all adopt the bend pipe form, coefficient of partial resistance relatively and the traditional water sealed cans decline of very big degree has been arranged, gas phase pipeline sectional area does not have significant change simultaneously, thereby this structure has farthest reduced droop loss.

2, sealing is tight.Tighter, more reliable than other seal valve, butterfly valve seal.Can adapt to gas phase media of different nature, as poisonous, the inflammable medium that waits.

Description of drawings

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

Fig. 2 is a user mode schematic representation of the present utility model.

Among the figure: 1, suction tude, 2, tank body, 3, intake-outlet, 4, flow-off, 5, steam outlet pipe.

Embodiment

With embodiment the utility model is illustrated in conjunction with the accompanying drawings:

As shown in Figure 1, a kind of U type tubular type water sealed tank, the tank body 2 of described water sealed tank is a U type structure, and the top of described tank body 2 has suction tude 1 and steam outlet pipe, and the lower end of tank body has intake-outlet 3, and on the tank body top of steam outlet pipe one side flow-off 4 is set.

As shown in Figure 2, when blocking gas phase media if desired, open water intake 3 and begin water inlet, under the pressure effect of gas phase media, U-shaped pipe both sides difference of liquid level occurs until reaching balance liquid level, realize efficient sealing effect, 4 may command liquid levels of flow-off prevent that liquid from entering in the gas phase media outlet conduit 5.

Open the gas phase media passage as need, then open water outlet 3, gas inlet tube 1 and gas outlet tube 5 UNICOMs, pipeline is opened.

Claims

1. U type tubular type water sealed tank, it is characterized in that: the tank body of described water sealed tank (2) is U type structure, the top of described tank body (2) has suction tude (1) and steam outlet pipe (5), and the lower end of tank body has intake-outlet (3), and on the tank body top of steam outlet pipe one side flow-off (4) is set.
