It is bright to consider effective, reliable sealing means and connection type.It is sealed in terms of high pressure Inlet and outlet water using copper packing, two sides are into medicine portion
Divide and uses O-shaped sealing ring sealing.
Working principle:
3 upper end of valve body of the present apparatus is high pressure intake, is equipped with high-pressure water inlet connector 1, lower end is high-pressure outlet, is equipped with
High pressure water outlet connector 10.High pressure water flow flows into this valve from water inlet, and when water flow flows to the upper end of spool 5, section becomes smaller, flow velocity
Accelerate；When water flow flows through the path cylindrical cavity 20 of the lesser straight section in 5 section of spool, continues flow down, section becomes more next again
Bigger, according to bernoulli principle, the flow velocity of fluid is bigger, and pressure is smaller, somewhere around here just forms local decompression, passes through operation
Control, left when two sides use flow control valve 6, right in the open state, the steel ball of two check valve assemblies with flow control valve 16
12 just under the action of negative pressure, compresses two compressed springs 11, two steel balls 12 are respectively between corresponding inner seal ring 13
In the open state, the liquid of two sides will be inhaled into spool 5 by check valve assembly, be mixed with the high pressure water of splash,
And it is discharged through water outlet.
Flow control valve 6, right flow control valve 16 are used by manually adjusting the left of two sides, can control the suction of two sides liquid
The liquid of the on-off entered, two sides can suck simultaneously, can also individually be sucked with side；And by adjusting the left with flow control of two sides
Valve 6 processed, it is right use flow control valve 16, can control the flow for the liquid being inhaled into.
Left in the two sides of this valve uses flow control valve 6, right use to use check valve assembly design on flow control valve 16,
To guarantee that the medical fluid of two sides can only enter on the inside of this valve from outside, and the high pressure water in valve will not be flowed out by the feeding opening of two sides
This valve.
Due to being operations involving high pressure, the present invention considers effective, reliable sealing means and connection type.High pressure Inlet and outlet water
Aspect is sealed using copper packing, and two sides use O-shaped sealing ring into medicine part and seal.
Using the present apparatus, high-pressure hydraulic pump is connected in the water inlet of this valve body 3, and water outlet connects giant, and two sides are with soft
The explosive barrel filled there are two types of additive is managed while being connected, the flow control valve of two sides is passed through, controls the on-off for the medical fluid that two sides are added
And additive amount, one can be completed cleaning process giant.This avoid the operations for being frequently replaced and cleaned apparatus, improve
Operating efficiency reduces the labor intensity of staff, decreases the investment for purchasing implement.
Bernoulli principle and siphon principle is utilized in the present apparatus, during entire dosing, does not need in addition to increase and fix
Investment, the not additional energy consumption of pilot process, also not extra discharge.
The present apparatus no matter shape or internal structure, have biggish difference with existing valve, present domestic manufacturer is still
The device for not producing similar functions has the device of the external similar functions of import, is singly that function is similar, no matter shape or internal
Structure differs larger；Domestic blank has been filled up in the appearance of the present apparatus for the first time；And the structure of the present apparatus is simple, processing and manufacturing
It is convenient, strong using function.
Above-mentioned specific embodiment cannot function as limiting the scope of the invention, for the technology people of the art
For member, any alternate modification or transformation made to embodiment of the present invention are fallen within the scope of protection of the present invention.
Place is not described in detail by the present invention, is the well-known technique of those skilled in the art of the present technique.
