T-type connects, and valve rod upper end is connect by the valve stem nut on holder with handwheel, and it is close that filler is arranged between valve rod periphery and valve deck
Seal apparatus；Mainly valve body forms three-port structure, first outlet by intake channel, first outlet channel, second outlet channel
Channel centerline, second outlet channel centerline, flashboard center line in approximately the same plane with valve rod vertical and intersectant centerline；The
One exit passageway inlet end face and second outlet channel entrance end face are respectively equipped with and the mutually matched sealing of one side plane of flashboard
Face, the flashboard other side are formed with lozenges and lower lozenges, are equipped with and upper lozenges phase in the valve chamber on the upside of valve body import channel
The upper wedging face mutually coordinated, is equipped in the valve chamber on the downside of valve body import channel and the mutually matched lower wedging face of lower lozenges；Lock
Both sides are respectively equipped with the guide groove along valve rod axis direction at plate central plane, and body cavity is equipped with and the guide groove phase interworking
The guiding rib of conjunction.
Preferably, the intake channel center line of valve body, first outlet channel centerline, second outlet channel centerline are same
It is mutually parallel in one plane, first outlet channel centerline and second outlet channel centerline are symmetricly set in intake channel
The both sides up and down of heart line.
Preferably, gate sealing surface and first outlet channel sealing surface, second outlet channel sealing surface distinguish built-up welding hard
Alloy.
Preferably, the upper wedging face of body cavity and the upper lozenges on lower wedging face and flashboard and lower lozenges difference
Pile-up welding hard alloy.
It is an advantage of the invention that valve body forms three-port structure, lock by intake channel, first outlet channel, second outlet channel
Plate respectively with first outlet channel and second outlet channel fitted seal, changing flow direction or the assignment of traffic to two exit passageways
Ratio is adjusted, and has the characteristics that simple in structure, good seal performance, two exit passageway assignment of traffic ratios are adjustable.
Description of the drawings
Fig. 1 is the structural schematic diagram of the present invention.
Specific implementation mode
Gate valve, including valve body 1, valve deck 6, valve rod 5, flashboard 4, handwheel 10 is adjusted in folding wedge compact form threeway as shown in Figure 1；
Inverted T shaped connection, 5 upper end of valve rod is used to connect with handwheel 10 by the valve stem nut 9 on holder 8 between 5 lower end of valve rod and flashboard 4
It connects, stuffing seal 7 is set between 5 periphery of valve rod and valve deck 6；Valve body 1 is by intake channel 12, first outlet channel 3,
Two exit passageways 2 form three-port structure, 3 center line of first outlet channel, 2 center line of second outlet channel, 4 center line of flashboard
In approximately the same plane with 5 vertical and intersectant centerline of valve rod, 3 center line of first outlet channel, 2 center line of second outlet channel and
4 center line of flashboard is mutually parallel in the horizontal direction；2 inlet end face of 3 inlet end face of first outlet channel and second outlet channel
It is respectively equipped with and is formed with lozenges and lower lozenges with the mutually matched sealing surface of 4 one side plane of flashboard, 4 other side of flashboard, into
Be equipped in the valve chamber of 12 upside of mouthful channel with the mutually matched upper wedging face 11 of upper lozenges, in the valve chamber of 12 downside of intake channel
Equipped with the mutually matched lower wedging face of lower lozenges 14；Both sides are respectively equipped with along 5 axis direction of valve rod at 4 central plane of flashboard
Guide groove, 1 internal chamber wall of valve body is equipped with and the mutually matched guiding rib of the guide groove 13.4 central plane of the flashboard is
Refer to by 5 center line of valve rod and with the plane of 4 central axis of flashboard.First outlet channel 3 connects user's heater import, the
Two exit passageways 2 constitute three-way pipeline by bypass pipe and user's heater outlet conduit, downstream line, go out in user's heater
Switch valve is installed on mouth pipeline.In the normal heating of user's heater, the switch valve on user's heater outlet conduit, which is in, to be opened
State is opened, flashboard 4 coordinates with the sealing of second outlet channel 2, and 12 medium of intake channel is taken by first outlet channel 3 into access customer
Warmer, then flow out to downstream line from user's heater outlet conduit；When needing user's heater to stop heating, user is taken
Switch valve on warmer outlet conduit is closed, and flashboard 4 coordinates with the sealing of first outlet channel 3, and 12 medium of intake channel passes through the
Two exit passageways 2, bypass pipe are flowed into downstream line；When needing to adjust user's heater flow, flashboard 4 is moved to first
Between exit passageway 3 and second outlet channel 2, a 12 medium part of intake channel is taken by first outlet channel 3 into access customer
Warmer enters downstream line, and another part is fed directly to downstream line by second outlet channel 2, bypass pipe, realizes user
Heater flow-rate adjustment, and the total flow for entering downstream line is constant, does not influence downstream user heating pressure.
12 center line of intake channel of valve body 1,3 center line of first outlet channel, 2 center line of second outlet channel are same
It is mutually parallel in a plane, 3 center line of first outlet channel and 2 center line symmetrical setting of second outlet channel are in intake channel 12
The both sides up and down of center line.
3 sealing surface of 4 sealing surface of flashboard and first outlet channel, 2 sealing surface of second outlet channel distinguish pile-up welding hard alloy,
Sealing surface wear-resisting property is improved, so that product is suitable for the industries such as oil, chemical industry, electric power, there is the threeway of abrasive media pipeline to cut
Change valve.
The upper wedging face 11 of 1 inner cavity of valve body and the upper lozenges on lower wedging face 14 and flashboard 4 and lower lozenges difference
Pile-up welding hard alloy reduces and is worn between 4 lozenges of flashboard and 1 wedging face of valve body, and it is logical with first outlet to improve 4 sealing surface of flashboard
Sealing matching property between 2 sealing surface of 3 sealing surface of road and second outlet channel.
