Examination.It is of course also possible to as spare feed liquor input port and it is spare go out liquid input port, can also with feed liquor input port and out liquid input
Mouth doubleway output reflux.
Inlet pipe 10 is respectively perpendicular with liquid access 11 out, feed liquor input channel 12, and outlet tube road 20 and feed liquor access
21, go out liquid output channel 22 to be respectively perpendicular, be easy to pipe, access turnery processing, it is convenient for production.
In addition, spacing is greater than between 10 outlet tube road 20 of inlet pipe between feed liquor input port 83 and out liquid delivery outlet 84
Spacing.That is feed liquor input port 83 and liquid delivery outlet 84 is staggeredly located position out, because of feed liquor input port 83 and liquid delivery outlet 84 out
Mating end is bigger than the mating end of liquid inlet and outlet matching hole, avoids the mating end interference of the two, in addition can provide more
Space, the curved of adjustment can be turned to by, which being applicable in, connects end.
In specific embodiment, inlet pipe 10 is equipped with the liquid access 11 out of three phase uniform intervals setting, outlet tube road
20, which are equipped with three, corresponds matched feed liquor access 21 with liquid access 11 out, any matching it is pairs of go out liquid matching hole 81 with
The line of feed liquor matching hole 82 is parallel with the first face.Shape is regular, easy to process.Its duct forms on similar dice six figure
Shape.
Function matching hole 7, out liquid matching hole 81, feed liquor matching hole 82, feed liquor input port 83, liquid delivery outlet 84 has respectively out
There is internal screw thread duct.
Function matching hole 7 goes out liquid matching hole 81, feed liquor matching hole 82, feed liquor input port 83, the opening for going out liquid delivery outlet 84
End is respectively equipped with sealing structure 9.The sealing structure 9 can improve mating leakproofness.
Specifically, sealing structure 9 includes single layer concave station sealing structure 91 or the double-deck concave station sealing structure 92.Single layer concave station is close
One preferred structure of seal structure, interior concave ring stage are equipped with for assembling the ring of sealing ring recessed 911.Single layer concave station sealing structure
Another preferred structure, interior concave ring stage be equipped with arc concave shape 912.
It is illustrated for arc concave shape 912, using cyclic sealing gasket, the inner ring diameter of cyclic sealing gasket is less than in arc
Recessed 912 wide mouth part diameter, during the crimping of outside, cyclic sealing gasket can be embedded in arc concave shape 912, realize sealing.
The above sealing structure 9 is relatively suitably applied in the cooling branching block of integrated form of this case.
