Stream intracavitary is connected to an adjusting rod.
It should be noted that above-mentioned example embodiment is to be located at false pressure head second body surface with one group of second opening
Illustrated exemplified by branch chamber, but the branch chamber 5 of the present invention can also include the of the second opening in the 3rd plane 13
Two groups of branch chambers.With reference to shown in figure 3, for the structural representation of another false pressure head component of the present invention.Wherein, branch chamber 5 also includes：
Second group branch chamber of second opening in the 3rd plane 13.Second group of branch chamber 52 includes successively dividing along through hole bearing of trend
The 4th branch chamber 54, the 5th branch chamber 55, the 6th branch chamber 56 that cloth and total depth are sequentially reduced.Wherein the 4th branch chamber 54
Coaxial with the first branch chamber 51, the 5th branch chamber 55 and the second branch chamber are coaxial, and the 6th branch chamber 56 and the 3rd branch chamber 53 are same
Axle.4th branch chamber 54 directly connects with negative pressure cavity 4, and the bottom of the 5th branch chamber 55 connects with the 4th branch chamber 54, the 6th point
The bottom of stream chamber 56 connects with the 5th branch chamber 55.4th branch chamber 54, the 5th branch chamber 55, correspondingly connect in the 6th branch chamber 56
It is connected to the 4th adjusting rod 34, the 5th adjusting rod 35, the 6th adjusting rod 36.It is identical with the first component stream chamber regulative mode, by according to
The 4th adjusting rod 34 of secondary regulation, the 5th adjusting rod 35, the 6th adjusting rod 36, the absorption length of false pressure head can be adjusted.This example
Property embodiment by first group of branch chamber and second group of branch chamber matching design, realize false pressure head bidirectional modulation absorption length
Purpose, add the adjustable range of false pressure head absorption length.
It should be noted that above-mentioned illustrated so that second group of branch chamber includes 3 branch chambers as an example, but in the present invention
Other exemplary embodiments in, second group of branch chamber can also include the branch chamber of other quantity.Such as second group of branch chamber
(n+1)th to 2n branch chamber can also be included, and the n-th+m branch chambers and m-th of branch chamber are coaxial；Wherein, (n+1)th shunting
Chamber directly connects with negative pressure cavity, and the n-th+m branch chambers are right by the (n+1)th to the n-th+m-1 branch chambers and negative pressure cavity indirect communication
Answer, adjusting rod is connected with each branch chamber.
False pressure head component in this illustrative embodiments can also include end cap 6, and end cap 6 offers with false pressure head body
The side connection that branch chamber second is open, this illustrative embodiments is by end cap 6 with entering exemplified by the connected mode of second surface 12
Row explanation.
It is adjusting rod and false pressure head component disassembly diagram with reference to shown in figure 4.It can be provided with end cap 6 and branch chamber opening
The corresponding screwed hole 61 in position；The diameter of screwed hole 61 is less than the diameter of branch chamber 5.
It should be noted that multiple fixing holes 62 can be provided with end cap 6, fixing hole 62 is passed through by end cap using screw
It is fixed on false pressure head second body surface 12.Adjusting rod 3 can partly set the outer spiral shell to match with the internal thread of screwed hole 61
Line, adjusting rod 3 are spirally connected with screwed hole 61, by the i.e. adjustable first end of adjusting rod 3 of rotation adjusting lever 3 in the position of branch chamber 5.
The first end of adjusting rod 3 can be removably connected with sealing ring 7, sealing ring 7 and shunting in this illustrative embodiments
Chamber 5 is in sealing contact.
Wherein, due to needing to stretch into branch chamber provided with externally threaded adjusting rod 3, the diameter of branch chamber is naturally larger than screwed hole
61 diameter.The needs of sealing ring 7 are in sealing contact with branch chamber, and the diameter of sealing ring 7 is necessarily not less than the diameter of branch chamber.Therefore
The first end of adjusting rod 3 for being provided with sealing ring 7 cannot pass through screwed hole 61 and stretch into branch chamber.
For this illustrative embodiments by the design of end cap, screwed hole is arranged on can be with the false dismantling connection of pressure head body 1
End cap 6 on.When mounted, the first end of adjusting rod is passed through into screwed hole 61 first；Then it is socketed in the first end of adjusting rod 3
Sealing ring 7, sealing ring is fixed on to the first end of adjusting rod 3 using back-up ring 8 and Screw 9；Finally by the first end of adjusting rod 3
Stretch into branch chamber 5, and end cap 6 is fixed on false pressure head second body surface 12.So as to solve adjusting rod first end not
The technical problem of branch chamber can be stretched into through screwed hole 61.
It should be noted that when branch chamber 5 includes second group of branch chamber, on the 3rd surface 13 of false pressure head body 1
It is provided with end cap.
Optionally, sealing ring 7, which can roll, is connected to the first end of adjusting rod 3, and when adjusting rod 3 rotates, sealing ring 7 is only dividing
The movement of the bearing of trend of chamber 5 is flowed, without being rotated with adjusting rod simultaneously, so as to reduce the damage of the friction between sealing ring 7 and branch chamber 5
Consumption, improves the service life of sealing ring 7, while reduce the power required for rotation adjusting lever 3.
In this illustrative embodiments, the end of adjusting rod 3 second can be connected with rotary handle, can be with by rotary handle 10
The position of adjusting rod 3 is adjusted, rotary handle can be polygon thread head or circular compass, and the present invention is not done to this
Go out specific restriction.
Adjusting rod is located at the inside of false pressure head body, when adjusting adjusting rod, can not observe adjusting rod and stretch into branch chamber
Depth.In this illustrative embodiments, adjusting rod 3 second is also provided with scale marker on end.When adjusting rod first end position
When branch chamber bottom, 0 graduation mark of scale marker aligns with the side of false pressure head body；Scale marker is from 0 graduation mark position
Gradually increase to the extreme direction of adjusting rod first.It can be judged according to the graduation mark to be alignd on adjusting rod with the side of false pressure head body
The absorption length of false pressure head.
In this illustrative embodiments, each adjustable range of adjusting rod 3 can be with identical, and the regulation for evenly distributing adjusting rod is grown
Degree can avoid some adjusting rod adjustment length long, prevent that equipment may be caused because length is long in action process
Action interference.
