Aperture indicating arm is arranged at the top of valve shaft, and it passes through the axle envelope on lid in control chamber.
Sealing ring pressing plate on main valve disc, sealing ring and main valve disc on main valve disc are housed in main valve disc seal, on main valve disc
Lower seal.
In upper seal, upper sealing ring is arranged in upper sealing ring pressing plate, and upper seal ring pressing plate is arranged on main valve epicoele and master
Valve lumen connection hole.
Waterpower triple valve provided by the utility model, barrier film in control chamber can be in the presence of upper and lower chamber differential water pressures
Above or move down, barrier film is connected by valve shaft with main valve disc, main valve disc can be made to move up or down therewith, and then make main valve
Lumen connects main valve epicoele or cavity of resorption, so as to realize the switching of path, can operate valve using the hydraulic pressure of pipeline itself, no
Need that the power sources such as motor are installed, hand all operates the minor valve also only needed on operational control pipeline, compared to traditional Three-way rotary valve
It is more laborsaving.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples：
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the utility model Fig. 1 A-A to sectional view.
Embodiment
As depicted in figs. 1 and 2, a kind of waterpower triple valve,
Including diaphragm type control chamber and it is arranged at the three-chamber main valve body 8 of diaphragm type control chamber bottom；
In diaphragm type control chamber, the space in control chamber between lid 1 and control chamber lower cover 4 forms control cavity, control chamber
Body inner space is separated into control chamber epicoele 2 and the two parts of control chamber cavity of resorption 5, control chamber epicoele 2 and control chamber epicoele by barrier film 3
Water inlet pipe 1a is connected, and control chamber cavity of resorption 5 connects with control chamber cavity of resorption water inlet pipe 4a, and the middle part of barrier film 3 passes through barrier film top board 3a
It is pressed abd fixed on barrier film lower platen 3b with nut on valve shaft 7；
In three-chamber main valve body 8, the inside of three-chamber main valve body 8 is divided into main valve epicoele 10, main valve lumen 11 and master
Valve cavity of resorption 12, main valve epicoele 10 are connected by main valve lumen 11 with main valve cavity of resorption 12, and valve shaft 7 passes through the axle envelope of control chamber lower cover 4,
It is connected with the main valve disc 9 in main valve lumen 11, it is close under the main valve disc on main valve disc 9 equipped with main valve disc seal and with guide grab
Seal pressing plate 9d；
Main valve epicoele 10 is provided with the upper seal being engaged with main valve disc seal with the connectivity part of main valve lumen 11, main
Valve lumen 11 is provided with the connectivity part of main valve cavity of resorption 12 and is engaged with being engaged guide grab on main valve disc lower seal pressing plate 9d
Lower sealing ring 8c, guide grab on the main valve disc lower seal pressing plate 9d with guide grab can in lower sealing ring 8c on move down
It is dynamic, so as to limit moving radially for main valve disc 9.
The edge of barrier film 3 is arranged in control chamber between lid 1 and control chamber lower cover 4, and blending bolt compresses.
Aperture indicating arm 6 is arranged on the top of valve shaft 7, and it passes through the axle envelope on lid 1 in control chamber.
Sealing ring pressing plate 9a on main valve disc, sealing ring 9b and master on main valve disc are housed in main valve disc seal, on main valve disc 9
Valve disc lower seal 9c.
In upper seal, upper sealing ring 8b is arranged in upper sealing ring pressing plate 8a, and upper seal ring pressing plate 8a is arranged on main valve
Chamber 10 and the connection hole of main valve lumen 11, upper sealing ring pressing plate 8a maximum outside diameter of the minimum diameter more than lower sealing ring 8c and master
The external diameter of valve disc 9.
The flange that can be connected with exterior line is installed on main valve epicoele 10, main valve lumen 11 and main valve cavity of resorption 12.
The course of work of the present utility model is as follows：
By installing appropriate control piper, make control chamber epicoele water inlet pipe 1a cut-in pressures water source, while make control chamber
Cavity of resorption water inlet pipe 4a drainings, now barrier film 3 can be moved down in the presence of differential water pressures, by valve shaft 7 make main valve disc 9 therewith to
Lower movement, main valve disc lower seal 9c and lower sealing ring 8c, which is formed, to be sealed, and main valve lumen 11 is kept apart with main valve cavity of resorption 12, and
Connected completely with main valve epicoele 10；Conversely, work as control chamber cavity of resorption water inlet pipe 4a cut-in pressures water source, while control chamber epicoele is intake
During pipe 1a drainings, main valve disc 9 moves up, and main valve lumen 11 is kept apart with main valve epicoele 10, and complete with main valve cavity of resorption 12
Connection.So just realize the switching of path.
Pressure water source typically may be derived from pressure highest one in three pipelines being connected with triple valve, and now barrier film 3 exists
Effective diameter in control chamber should be greater than the external diameter of main valve disc 9, the pressure on main valve disc 9 is consistently less than the pressure of the both sides of barrier film 3
Power is poor, to ensure that valve can be operating normally.
