Abstract
The utility model relates to a water cooling device, in particular to a water cooling device of a semi-ball valve of an RH furnace. A water cooling sleeve with a water inlet and a water outlet is connected between the semi-ball sealing valve and a blanking conduit. The water cooling device has compact structure, small occupying space, little expense, convenient installation, low manufacturing cost and simple adjustment, can reduce the consumption of the semi-ball effectively, and reduce the disadvantageous effects of the damage to the semi-ball valve on production.
Description
Technical field
The utility model relates to a kind of water cooling plant, a kind of specifically RH stove semisphere valve water cooling plant.
Background technology
At present, the real life-span of using of the blanking conduit episphere seal valve of RH stove design also can only reach 1 month in the world, and the rear quarter seal valve had also just lost its due effect in 1 month.Main cause is that the hemisphere seal valve directly contacts with the blanking conduit, and the blanking conduit can directly conduct the heat in the vacuum tank to the hemisphere seal valve, causes the damage of hemisphere seal valve sealing ring, and the damage of valve body, thereby lose sealing effectiveness, cause the unusual of vacuum.The hemisphere seal valve is an import parts, is worth about 400,000 yuan, thereby causes expense to strengthen.
Summary of the invention
Technical problem to be solved in the utility model is: at the shortcoming of above prior art existence, a kind of RH stove semisphere valve water cooling plant is proposed, compact conformation, expense is few, can effectively reduce the consumption of semisphere valve, the damage that reduces because of semisphere valve causes the production adverse influence.
The technical scheme that the utility model solves above technical problem is:
RH stove semisphere valve water cooling plant is connected to a water cold sleeve that is provided with intake-outlet between hemisphere seal valve and blanking conduit.
The upper end of water cold sleeve is connected with the hemisphere seal valve by flange, lower end and the welding of blanking conduit.Separate with dividing plate between the intake-outlet.
Water cold sleeve is connected with a control valve by a metal hose, and control valve is located at one that gate valve is connected on the total equipment waterpipe of RH stove by a transition conduit.Perforate welding point on the total equipment waterpipe of RH stove is installed gate valve by joint.
The utility model compact conformation, institute takes up space little, and expense is few, and is easy for installation, cheap, adjusts simply, can effectively reduce the consumption of semisphere valve, and the damage that reduces because of semisphere valve causes the production adverse influence.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Embodiment one
The structure of present embodiment as shown in Figure 1, RH stove semisphere valve water cooling plant is connected to a water cold sleeve 1 that is provided with intake-outlet between hemisphere seal valve and blanking conduit.Water cold sleeve 1 is provided with water inlet 2 and delivery port 3, and inside separates with dividing plate, and the upper end of water cold sleeve 1 is connected with the hemisphere seal valve by flange, lower end and the welding of blanking conduit.Water cold sleeve 1 is connected with a control valve by a metal hose, and control valve is located at one that gate valve is connected on the total equipment waterpipe of RH stove by a transition conduit.Perforate welding point on the total equipment waterpipe of RH stove is installed gate valve by joint.
Installation process of the present utility model is as follows: after making water cold sleeve 1 of the present utility model, select the installation site, be connected with the hemisphere seal valve by flange, the other end and the welding of blanking conduit.Choose and carry out the gate valve that the perforate welding point is installed DN50 on the total equipment waterpipe of RH stove, by carrying out the installation of control valve behind the changeover portion.By metal hose water cold sleeve 1 is connected with control valve, opens valve.Draw the moving source gas of one road nitrogen after installing, and control valve opening is adjusted to suitable position as control valve.The heat conduction of thermal current that produces in the cooling production process by water cold sleeve 1 and blanking conduit self all can significantly be reduced, thereby protection hemisphere seal valve 1 can normally use.
The utility model can also have other embodiment, and the technical scheme that equal replacement of all employings or equivalent transformation form all drops within the claimed scope of the utility model.
