The characteristics of the utility model is：Four control valve H type attachment structures, not only with compact-sized, small volume, meet
Installation and requirement in small space, operation and allotment control are also facilitated, steam supply is steadily balanced, and end will not occur
The problem of terminal device steam supply deficiency, while the Collaborative Control of four delivery outlets and four control valves is reasonably set, can be with
Realize a variety of output services patterns.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
As shown in figure 1, tetrad valve group peculiar to vessel of the present utility model is made up of four control valves and connection member, four
Control valve is gate valve, and connection member is three-way pipe.Four one group two-by-two of control valves 1,2,3,4, one of which control valve 1,3 passes through
Three-way pipe A is connected in series, and another group of control valve 2,4 is connected in series by three-way pipe B.Two three-way pipes A, B branch pipe mouth of pipe phase
To setting, and three-way pipe C is bridged, two groups of control valves after bridge joint are in H type structures.Above-mentioned control valve and three-way pipe, each three-way pipe
Between connected mode for welding.The three-way pipe C branch pipe mouth of pipe is delivery outlet 5, and delivery outlet is set upward, is arranged on for connecting
Terminal device above tetrad valve group.The arrival end of one group of control valve is welded with three-way pipe D, three-way pipe D and one on ship
High temperature and high pressure steam source connects, and the three-way pipe D branch pipe mouth of pipe is delivery outlet 6, and delivery outlet is set towards outside, can also be towards its other party
To setting.The arrival end of another group of control valve is welded with three-way pipe E, three-way pipe E and another high temperature and high pressure steam source on ship
Connection, the three-way pipe E branch pipe mouth of pipe is delivery outlet 7, and delivery outlet sets towards outside, can also set towards other directions.Three-way pipe
D, E is reducer tee piece, i.e., the undergauge at three-way pipe D, E branch pipe, steam is through three-way pipe branch pipe shunting output to steam demand
Measure small terminal device.Two groups of control valve outlets are both connected on reducing bend three-way pipe 8, wherein the port of export of control valve 3 with
One branch pipe of reducing bend three-way pipe is connected by flange 9, the port of export of control valve 4 and another branch pipe of reducing bend three-way pipe
Connected by flange 10, stress build up can be avoided using flange connection, and be easy to maintain.Reducing bend three-way pipe
Supervisor's mouth of pipe is delivery outlet 11.Reducing bend three-way pipe is expanding on supervisor, and solving two vapour sources, steam supply causes simultaneously
The problem of reducing bend three-way pipe convergence overload.By 6,7 sections of reducings of delivery outlet in three-way pipe D, E, and set via three
Individual three-way pipe A, B, C collect the delivery outlet 5 of output, increase flow resistance, reduce the steam output quantity of delivery outlet 5,6,7, simultaneously
During to four terminal device steam supplies, more steam flow terminal devices 8, ensure that terminal device steam supply is balanced, meet each terminal
