Description

Quick closing water seal valve

technical field

The utility model relates to the technical field of valves, in particular to a quick-closing water-sealed valve.

Background technique

In the iron and steel metallurgy industry, the temperature of gas is very high, around 300-400°C, and some even reach 600°C. If valves such as butterfly valves or gate valves are used as cut-off valves, the temperature will be too high and the temperature difference will be too large, and the steel will expand due to heat. The impact of cold shrinkage will lead to poor sealing, gas leakage, and gas waste, so it is generally selected for this matching water seal valve. However, the existing water-sealed valve mainly cuts off the gas path by injecting water to stop the gas supply, and then drains the water to continue the gas supply. This takes a long time, does not meet the actual operation requirements, and greatly affects the work efficiency. .

Contents of the invention

In view of the above-mentioned problems, the purpose of this utility model is to provide a quick-closing water-sealed valve with simple structure, easy to use, which can quickly cut off gas and improve work efficiency.

Realize the technical scheme of the utility model as follows:

The quick-closing water-sealed valve includes a valve body with an air inlet and an air outlet, a water tank is arranged in the valve body, sealing water is arranged in the water tank, the air outlet is arranged above the sealing water, and a movable bell valve is arranged in the water tank. The valve body is provided with a driving device connected with the movable bell valve and driving its movement.

With the above-mentioned scheme, the sealing water in the water tank is mainly used to seal the gas outlet to realize the function of cutting off the gas. During operation, the movable bell valve is moved downward through the action of the driving device so that it is submerged in the sealing water. Until the air outlet is completely blocked by the sealing water, the gas cannot go out from the air outlet, thereby realizing the cut-off function. When the gas supply needs to be continued, just lift the movable bell valve upward, so that the sealing water will drop to the bottom of the air outlet. Thereby the gas can be supplied again, and the effect of the driving device and the movable bell valve realizes fast cut-off and communication, the time is greatly shortened, and the working efficiency is improved.

The driving device is arranged on the top of the valve body, and the driving device includes a frame fixedly connected with the valve body. A guide rail parallel to the frame image and a lifting device are sequentially connected between the lower support plates, and a movable plate is also connected to the guide rail and the lifting device, and a connecting rod is connected to the movable plate, and the connecting rod is fixed to the movable bell valve. Connection, the advantage is driven by the lifting device, the movable plate drives the connecting rod to move up and down, that is, the movable bell valve also moves up and down, so that the sealing water can seal or connect the air outlet, and the guide rail can guide the movable plate so that it goes up and down along the guide rail movement to prevent the tilt from getting stuck and preventing it from working.

The lifting device is a lead screw, the upper end of the lead screw is connected with a motor, and the motor is arranged on the upper support plate and drives the lead screw to move.

The air outlet is set upwards, which can prevent the sealing water from flowing away from the air outlet when the sealing water seals the air outlet. There is a water outlet connected to the water tank on the valve body, which is convenient for draining and changing water. The lower end of the valve body is provided with a sewage outlet. Advantages When cleaning the inside of the valve body, water can be passed through the air inlet for cleaning, and then the sewage can be discharged through the sewage outlet, which is simple and convenient.

Detailed ways

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

As shown in Figure 1, the fast closing water seal valve includes a valve body 1 with an air inlet 2 and an air outlet 3, a water tank 4 is provided in the valve body 1, a sealing water 5 is provided in the water tank 4, and the air outlet 3 is arranged on Above the sealing water 5, a movable bell valve 6 is arranged in the water tank 4, and a driving device 7 connected with the movable bell valve 6 and driven to move is provided on the valve body 1.

The driving device 7 is arranged on the top of the valve body 1. The driving device 7 includes a frame 71 fixedly connected to the valve body 1. The frame 71 is vertically arranged. The frame 71 is provided with an upper support plate 72 vertically connected with it and The lower support plate 73, the upper support plate 72 and the lower support plate 73 are connected with a guide rail 74 parallel to the frame 71 and a lifting device 75 successively, and the movable plate 76 is also connected on the described guide rail 74 and the lifting device 75. The movable plate 76 is connected with a connecting rod 77, and the connecting rod 77 is fixedly connected with the movable bell valve 6. The advantage is that driven by the lifting device, the movable plate drives the connecting rod to move up and down, that is, the movable bell valve also moves up and down, so that the sealing water The air outlet can be sealed or communicated, and the guide rail can guide the movable plate so that it moves up and down along the guide rail to prevent the tilt from being stuck, so that it cannot work.

The lifting device 75 is a leading screw, and the upper end of the leading screw is connected with a motor 78, and the motor is arranged on the upper support plate and drives the leading screw to move.

The air outlet 3 is arranged obliquely upward. When the sealing water seals the air outlet, it can prevent the sealing water from flowing away from the air outlet. The valve body 1 is provided with a water outlet 8 connected with the water tank 4, which is convenient for draining and changing water. There is a sewage outlet 9, and the advantage is that when cleaning the inside of the valve body, water can be passed into the air inlet for cleaning, and then the sewage is discharged through the sewage outlet, which is simple and convenient.
