Abstract
The utility model discloses a water cooling butterfly valve in the high temperature condition butterfly valve field, comprises a valve housing, a valve disc and a valve rod, wherein, the valve disc is correspondingly arranged in the valve housing; the valve rod passes through the valve housing; the valve disc is fixed with the center of the valve rod; a cooling water jacket is arranged in the valve housing; the center of the valve rod is provided with a cooling water channel which axially passes through the valve rod; the cooling water jacket and the cooling water channel are respectively communicated with a water inlet and a water outlet. When the utility model works, the cooling water can be injected through the water inlet, and lowers the temperatures of the valve housing, the valve rod and the valve disc after heat exchange in the valve housing and the valve rod, and leaves the device from the corresponding water outlet, heat can be constantly taken away during the constant circulation of the cooling water, so the valve housing, the valve rod and the valve disc can work in the environment with lower temperature. Compared with the prior art, the utility model can bear higher environmental temperature, and can be used in the working situation with high temperature.
Description
Technical field
The utility model relates to a kind of valve, particularly a kind of butterfly valve that is used for worst hot case.
Background technique
Butterfly valve of the prior art mainly is made up of valve casing, valve disc and valve rod etc., and valve disc is equipped with in valve casing, valve rod passes valve casing, and valve disc and valve rod middle part fix, and the valve rod top is provided with operating mechanism and rotates with the control valve rod, drive valve disc when valve rod rotates and rotate, realize the opening and closing of valve; Its deficiency is: this valve can only use in the lower workplace of temperature, can not be used for the high temperature occasion.
The model utility content
The purpose of this utility model provides a kind of water-cooled butterfly valve, makes it can be applied in the workplace of high temperature.
The purpose of this utility model is achieved in that the water-cooled butterfly valve, comprise valve casing, valve disc and valve rod, valve disc is equipped with in valve casing, valve rod passes valve casing, valve disc and valve rod middle part fix, be provided with cooling water chamber in the valve casing, valve rod central authorities are provided with the cooling water channel that axially runs through valve rod, and described cooling water chamber and cooling water channel have been connected water intake and water outlet respectively.
During the utility model work, can inject cooling water by water intake, cooling water has reduced the temperature of valve casing, valve rod and valve disc after heat exchange in valve casing and valve rod, cooling water in the continuous circulation of cooling water, is constantly taken away heat from corresponding water outlet separating device, valve casing, valve rod and valve disc can be operated under the lower temperature environment, compared with prior art, the utility model can tolerate higher ambient temperature, can be used in the hot operation occasion.
For easily manufactured, valve casing can be made up of two-part, being respectively housing that has cooling water chamber and the cover plate that is enclosed in the cooling water chamber outside forms, cover plate can be separated with housing, can make things convenient for the processing of cooling water chamber like this, housing can adopt foundry goods, install cover plate after, form complete valve casing.
