Abstract
The utility model relates to a quick closing valve water seal valve, including the valve body that has air inlet and gas outlet, being equipped with the basin in the valve body, being equipped with sealed water in the basin, the gas outlet sets up in the top of sealed water, is equipped with movable clock valve in the basin, is equipped with the drive arrangement who links to each other with activity clock valve and drive its motion on the valve body. The utility model has the characteristics of simple structure, convenient to use can cut off coal gas fast, improves work efficiency etc.
Description
Technical field
The utility model relates to valve technology field, particularly quick closing valve water-sealing valve.
Background technique
In iron and steel metallurgical industry, the temperature of coal gas is very high, and at about 300-400 DEG C, what have even reaches 600 DEG C, if with the valve such as butterfly valve or gate valve as cut-off valve, can because temperature be too high, excessive temperature differentials, the impact that iron and steel is expanded with heat and contract with cold, then can cause poorly sealed, leakage gas, causes gas to waste, and is thus generally selected to this supporting water-sealing valve.But existing water-sealing valve mainly realizes cutting off gas circuit by water filling stops air feed, then to drain continuation air feed at Jiang Shui, needs is chronic like this, does not meet practical operation requirement, greatly have impact on working efficiency.
Summary of the invention
For the problems referred to above, it is simple that the purpose of this utility model is to provide a kind of structure, easy to use, energy fast shut-off coal gas, the quick closing valve water-sealing valve of increasing work efficiency.
Realize the technical solution of the utility model as follows:
Quick closing valve water-sealing valve, comprises the valve body with suction port and air outlet, is provided with tank in described valve body, sealing water is provided with in tank, air outlet is arranged on the top of sealing water, is provided with movable bell valve in tank, and valve body is provided with and is connected with movable bell valve and drives the drive unit that it moves.
Have employed above-mentioned scheme, sealing water in tank is mainly used for air outlet to seal, realize the function cutting off coal gas, during operation, by the effect of drive unit, movable bell valve is moved downward, it is made to submerge in sealing water, until air outlet is blocked by sealing water completely, such coal gas just cannot be gone out from air outlet, thus realize cutting function, when needing to continue air feed, only movable bell valve upwards need be promoted, such sealing water will drop to below air outlet, thus coal gas can air feed again, achieve fast shut-off by drive unit with the effect of movable bell valve and be communicated with like this, time shortens greatly, improve working efficiency.
Drive unit is arranged on the top of valve body, this drive unit comprises the frame be fixedly connected with valve body, this frame is vertically arranged, frame is provided with perpendicular connected upper backup pad and lower supporting plate, be connected with in turn between upper backup pad and lower supporting plate with frame as parallel guide rail and lifting device, described guide rail and lifting device are also connected with mobile plate, this mobile plate is connected with connecting rod, described connecting rod is fixedly connected with movable bell valve, advantage is driven by lifting device, mobile plate drives connecting rod to move up and down, namely movable bell valve also moves up and down, thus make sealing water can by gas outlet seal or connection, guide rail can lead to mobile plate, it is moved up and down along guide rail, prevent inclination from blocking, so that cannot work.
Lifting device is leading screw, and leading screw upper end is connected with motor, and motor to be arranged on upper backup pad and to drive guide screw movement.
Air outlet tilts upward setting, can prevent sealing water from flowing away from air outlet when sealing water seal and living air outlet, valve body is provided with the water outlet be connected with tank, be convenient to draining and change water, valve body lower end is provided with sewage draining exit, and advantage is when cleaning valve inner, can pass into water clean from suction port, then by sewage draining exit, sewage is being discharged, simple and convenient.
