The utility model has the advantages that valve body forms threeway knot by intake channel, first outlet channel, second outlet channel
Structure, flashboard are sealed with first outlet channel and the cooperation of second outlet channel respectively, changing flow direction or the stream to two exit passageways
Amount allocation proportion is adjusted, and has the spies such as structure simple, good seal performance, two exit passageway assignment of traffic ratios are adjustable
Point.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The dedicated regulating three-way valve of heating device pipeline as shown in Figure 1, including valve body 1, valve deck 6, valve rod 5, flashboard 4, handwheel
10;Inverted T shaped connection is used between 5 lower end of valve rod and flashboard 4,5 upper end of valve rod passes through the valve stem nut 9 and handwheel 10 on bracket 8
Stuffing seal 7 is arranged in connection between 5 periphery of valve rod and valve deck 6;Valve body 1 by intake channel 12, first outlet channel 3,
Second outlet channel 2 forms three-port structure, 3 center line of first outlet channel, 2 center line of second outlet channel, 4 center of flashboard
Line in 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
It is parallel to each other in the horizontal direction with 4 center line of flashboard;2 input end of 3 inlet end face of first outlet channel and second outlet channel
Face, which is respectively equipped with, 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,
It is equipped in the valve chamber of 12 upside of intake channel and the mutually matched upper wedging face 11 of upper lozenges, the valve chamber of 12 downside of intake channel
It is interior to be equipped with and the mutually matched lower wedging face 14 of lower lozenges;Two sides are respectively equipped with along 5 axis side of valve rod at 4 central plane of flashboard
To guide groove, 1 internal chamber wall of valve body be equipped with and the mutually matched guiding rib 13 of the guide groove.4 central plane of flashboard
Refer to the plane by 5 center line of valve rod and with 4 central axis of flashboard.First outlet channel 3 connect user's heater 15 into
Mouthful, second outlet channel 2 constitutes three-way pipeline by bypass pipe and 15 outlet conduit of user's heater, downstream line, in user
Switch valve 16 is installed on 15 outlet conduit of heater.In user's 15 normal heating of heater, 15 outlet conduit of user's heater
On switch valve 16 it is in the open state, flashboard 4 and second outlet channel 2 sealing cooperate, 12 medium of intake channel pass through first
Exit passageway 3 enters user's heater 15, then flows out to downstream line from 15 outlet conduit of user's heater;When needing user to take
When warmer 15 stops heating, the switch valve 16 on 15 outlet conduit of user's heater is closed, flashboard 4 and first outlet channel 3
Sealing cooperation, 12 medium of intake channel are flowed into downstream line by second outlet channel 2, bypass pipe;When needing to adjust user
When 15 flow of heater, flashboard 4 is moved between first outlet channel 3 and second outlet channel 2,12 medium one of intake channel
Part by first outlet channel 3 enter user's heater 15 enter downstream line, another part by second outlet channel 2,
Bypass pipe is fed directly to downstream line, realizes that user's heater flow is adjusted, and the total flow for entering downstream line is constant, no
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 parallel to each other 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 two 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 petroleum, 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 upper lozenges and lower lozenges difference on lower wedging face 14 and flashboard 4
Pile-up welding hard alloy reduces and wears between 4 lozenges of flashboard and 1 wedging face of valve body, improves 4 sealing surface of flashboard and first outlet is logical
Sealing matching property between 2 sealing surface of 3 sealing surface of road and second outlet channel.
