Coordinate with venthole sealing；During use, the venthole is welded to connect with the upper cylinder half of the steam turbine.
Further improve as this utility model, including sleeve, on the inwall of the sleeve, annular is provided with several gas
Close groove, the valve handle activity are plugged in the sleeve, and are fixed on the valve casing by the sleeve seal.
Further improve as this utility model, on the valve casing, be vertically provided with multiple transfer ports, the transfer port and institute
State sleeve to be connected.
Further improve as this utility model, including valve seat, the valve seat is in hollow tube-shape, and the valve seat is set in described
In venthole, and its left side is provided with the first taper seat, and the valve disc is matched somebody with somebody by first taper seat and the valve base sealing
Close.
Further improve as this utility model, the right side of the valve disc is provided with and is engaged with first taper seat
The second taper seat.
Prior art is contrasted, the beneficial effects of the utility model are：
This utility model simple structure, easy to use, large tonnage steam pressure of can weighing, with higher safety
Coefficient；The stop valve control of this kind of structure is flexible simultaneously, and during use, venthole is directly welded on the casing top half of steam turbine, is saved
Main steam pipe is removed, has been taken up room less, and it is easy for installation, effectively save field-erection time, convenient and hommization.
Description of the drawings
Fig. 1 is the structural representation of this utility model steam turbine integrated main steam valve；
In figure：1st, valve casing, 2, air intake, 3, venthole, 4, valve rod, 5, valve disc, 6, sleeve, 7, airtight groove, 8, transfer port,
9th, valve seat, the 10, first taper seat, the 11, second taper seat.
Specific embodiment
The utility model is described in more detail with specific embodiment below in conjunction with the accompanying drawings.
As shown in figure 1, this utility model provides a kind of steam turbine integrated main steam valve, its structure includes, including valve casing
1, the venthole 3 for being respectively arranged with air intake 2 on the valve casing 1 and being connected with the air intake 2, the air intake 2 are vertically set
Put, the venthole 3 is horizontally disposed with；Including horizontally disposed valve rod 4 and valve disc 5, the valve disc 5 is arranged at the valve rod 4
One end, 4 activity of the valve rod is plugged in the valve casing 1, and passes through the valve disc 5 and the sealing of the venthole 3 coordinates；Make
Used time, the venthole 3 are welded to connect with the upper cylinder half of the steam turbine.
As shown in figure 1, a kind of steam turbine integrated main steam valve of this utility model, its structure is also including sleeve 6, the sleeve
On 6 inwall, annular is provided with several airtight grooves 7, and 4 activity of the valve rod is plugged in the sleeve 6, and passes through the sleeve 6
It is sealingly fastened on the valve casing 1.Arrange sleeve 6 to coordinate with the sealing of valve rod 4, can effectively prevent steam from carrying out along valve rod 4
Leakage, with preferable sealing effectiveness；Several airtight grooves are set in 6 annular of sleeve simultaneously, it is possible to use airtight groove enters one
Step is sealed to valve rod, can further prevent steam from seepage at valve rod 4, further makes this utility model have higher gas
Close property.
As shown in figure 1, being vertically provided with multiple transfer ports 8 on the valve casing 1, the transfer port 8 is connected with the sleeve 6
It is logical.Arrange transfer port 8 effect be：To collect along the steam that valve rod is leaked, be transmitted to the equipment such as airtight heater
Heat exchange, the waste of steam of prevent leakage, more environmentally-friendly and hommization are carried out inside.
