Specific embodiment
Specific embodiments of the present invention will be further explained by 1-3 with reference to the accompanying drawing.
The dedicated coaxial valve group of shield machine shield tail injected grease, including valve block group, gas control coaxial valve plug-in unit 6 and outlet end cap 8；Valve block
Organizing includes at least one valve block 1, at least one valve block 22, and the section of valve block 1 and valve block 22 is square, this shape
It is easy to process and can greatly reduce processing cost, valve block 1 with laterally and be connected in valve block 22 and offer valve block through-hole,
The top of valve block through-hole has been sequentially communicated valve block outlet, connecting bushing location hole, interleaved in valve block 1 and valve block 22
It connects equipped with screw hole and by screw 1, is positioned between valve block 1 and valve block 22 radial through steel bushing 1, on steel bushing 1
It is inlaid with sealing ring, the end connection blind plate of valve block group or inlet flange 12, the one end that can be valve block group are connected with blind plate
4, the other end is connected with inlet flange 12 by steel bushing 2 11, and the both ends for being also possible to valve block group pass through steel bushing 2 11 and are connected with
Inlet flange 12 is inlaid with sealing ring on steel bushing 2 11；The connecting bushing of connecting bushing location hole and gas control coaxial valve plug-in unit 6 connects
It connects, the valve seat of gas control coaxial valve plug-in unit 6 is connect with outlet end cap 8, passes through spiral shell between valve block 1, valve block 22 and outlet end cap 8
27 connections are followed closely, the side wall of outlet end cap 8 offers reserved screwed hole, can be equipped with flowmeter or pressure in reserved screwed hole
Force snesor can also be equipped with plug screw 9 by gasket 10 in reserved screwed hole.
It is a kind of to have gathered manifold-type coaxial valve, main line or bye-pass flowmeter (switch), main line or bye-pass pressure
The control valve groups such as switch (sensor), guide's gas source, ball valve and pipe fitting.The valve group can be used for shield machine high-pressure grease pouring system
System, can be used for pressure common cooling system.Inherit the innate advantage of coaxial valve: antipollution, high pressure resistant, low starting pressure
Power.Can be carried out in same valve group high-low pressure subregion, mountable different negotiabilities single valve, different medium can be achieved control,
The vacancy of the following extension can be reserved, converging, the multiple functions such as gas, electricity and sensor being integrated for different medium can be achieved, significantly
Improve product itself to the adaptability of environment.
Pipeline is substituted with valve block, is easily installed and is dismantled, and reduces leakage point；Valve block intermediate throughholes can be done arbitrarily large
Small, to meet field demand, adaptability is stronger；It is radially positioned, is inlayed on steel bushing 1 close with steel bushing 1 between valve block and valve block
Seal guarantees No leakage between valve block and valve block；It is axial to be connected and fixed with screw 1, spring washer；Valve block is divided to two kinds, such valve block
Quantity arbitrarily can arbitrarily increase and decrease according to field demand, and single valve is directly fixed in valve block with screw 27, outlet end cap 8
Reserved screwed hole can be sealed, mountable flowmeter or pressure sensor with plug screw 9 when not used；Valve group medium inlet or outlet
Connection type can arbitrarily be changed according to client's needs (inlet flange 12, blind plate 4).
The present invention meets live actual demand by arbitrarily increasing valve block quantity, and assembles valve group, fundamentally solves
Certainly narrow space, it is difficult to installation or the problems such as later maintenance.
More than, it is merely preferred embodiments of the present invention, but scope of protection of the present invention is not limited thereto, it is any
Those familiar with the art within the technical scope of the present disclosure, according to the technique and scheme of the present invention and its invents
Design is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
