Specific embodiment
The technical solution of the utility model is further elaborated with reference to the accompanying drawing.
It is shown in Figure 1, a kind of above-mentioned Gas-liquid mixing valve, including with the first cavity 1 the first valve seat 2, have second
Second valve seat 4 of cavity 3.In the present embodiment, the first cavity 1 and the second cavity 3 all have upward opening, the first valve seat 2
Cylindrical with the main body of the second valve seat 4, the main body of the first cavity 1 and the second cavity 3 is also cylindrical.
Gas-liquid mixing valve further includes the cover board 5 for sealing the second cavity 3, up and down set on the top of the second valve seat 4
The spool 6 being arranged in the second cavity 3 and cover board 5, between the outside circumference of spool 6 and the inside circumference of the second valve seat 4 between
Gap distribution, forms admission chamber.In the present embodiment, the second valve seat 4 extends downwardly shape including valve seat body 41, by valve seat body 41
At the first extension 42 for protruding into the first cavity 1, the use that is extended outward to form by the outside circumference of valve seat body 41
In the second extension 43 for sealing the second cavity 3, between the outside circumference of the first extension 42 and the inside circumference of the first valve seat 2
Gap distribution forms inlet chamber, i.e. gas-liquid mixed chamber.In the present embodiment, valve seat body 41 and the first extension 42 are in circle
Cylindricality, the diameter of valve seat body 41 are greater than the diameter of the first extension 42, and spool 6 is movable simultaneously along the vertical direction to be arranged in valve
In seat ontology 41 and the first extension 42, the first extension 42 is distributed along the vertical direction with the coaxial extension of spool 6, axial line；
Second extension 43 extends outwardly in the horizontal direction, and the second extension 43 is in a ring.
Gas-liquid mixing valve further includes the inlet tube 7 being connected to the second cavity 3 being set in valve seat body 41, is opened in first
The liquid outlet 8 of 42 bottom of extension, is set to the first valve seat 2 at the air inlet pipe 9 being connected to the first cavity 1 on the first valve seat 2
The discharge nozzle 10 for being located at 8 lower section of liquid outlet of bottom.In the present embodiment, inlet tube 7 is opened in valve seat body in the horizontal direction
41 side, air inlet pipe 9 are then opened in the side of the first valve seat 2 in the horizontal direction；Second cavity 3, liquid outlet 8, goes out spool 6
Expects pipe 10 is coaxial to be extended, and axial line is distributed along the vertical direction.It is arranged by this, below liquid outlet 8, compressed gas is surround
The liquid outlet 8, the distance between 8 bottom end of liquid outlet and 10 top of discharge nozzle are smaller, compressed gas can with higher flow velocity with
The liquid mixing flowed out at liquid outlet 8, mixes gas and liquid more evenly.
Spool 6 include for contradicting the inside circumference of the first extension 42 with prevent that liquid enters in the first cavity 1 the
One end 11, in the present embodiment, first end 11 are used to contradict the bottom of the first extension 42.First end 11 contradicts first
When extension 42, the distance that the bottom of spool 6 extends along a length thereof the bottom that direction is higher by the first extension 42 is d, wherein 0≤
D≤3mm, since the first extension 42 has certain thickness, the bottom of the first extension 42 said herein is the first extension
At the minimum point in portion 42.It is arranged by this, makes to control whether liquid passes through the first end that liquid outlet 8 enters the first cavity 1
Closer distance is kept between 11 and gas-liquid mixed point, even if the connectivity part of the first cavity 1 and the second cavity 3 generates negative pressure,
It can guarantee that liquid is full of inlet tube 7 and the second cavity 3 when persistently mixing with gas always, to guarantee liquid flow when mixing
The stability of amount.When d is 0, first end 11 is contradicted in the bottom of the first extension 42, for preventing liquid from entering the first chamber
In body 1, at this point, liquid can be covered with entire second cavity 3 and inlet tube 7, when spool 6 is upwardly away from liquid outlet 8, the second cavity
It will not cause liquid that cannot be covered with the second cavity 3 and inlet tube in lasting mixing due to the negative pressure generated at liquid outlet 8 in 3
7.First end 11 plays the role of switch valve to the liquid in the second cavity 3, by controlling the size of d, can control
Switch valve and the first cavity 1 keep closer distance.
The outside circumference of first valve seat 2 extends outward to form the third extension 12 positioned at 43 lower section of the second extension,
In the present embodiment, third extension 12 extends outwardly in the horizontal direction, third extension 12 in a ring, third extension 12 it is outer
Diameter is identical as the outer diameter of the second extension 43.
Gas-liquid mixing valve further includes the first fixed mechanism for being fixed on third extension 12 on second extension 43
13, for cover board 5 to be fixed on to second fixed mechanism 14 on 41 top of valve seat body.In the present embodiment, the first fixed mechanism
13 and second fixed mechanism 14 be fixing bolt.
Gas-liquid mixing valve further includes set on the first sealing between first end 11 and the inside circumference of the first extension 42
Part 15.In the present embodiment, first seal 15 is that sealing ring is passed through by the way that first seal 15 is arranged in first end 11
When first seal 15 contradicts the first extension 42, it can guarantee the sealing effect between the first cavity 1 and the second cavity 3, have
The prevention liquid of effect enters in the first cavity 1.
Gas-liquid mixing valve further includes the second seal 16 being set between spool 6 and cover board 5, set on the upper of valve seat body 41
Third sealing element 17 between surface and the lower surface of cover board 5.In the present embodiment, second seal 16 and third sealing element 17
It is sealing ring, second seal 16 is sheathed on spool 6, can by setting second seal 16 and third sealing element 17
The medium in the second cavity 3 is prevented to leak to outside.
Gas-liquid mixing valve further includes the 4th close between the lower surface of valve seat body 41 and the upper surface of the first valve seat 2
