For shape to be detached from the cam of annular groove axial limiting, the cam single-degree-of-freedom is rotationally connected with valve body.
Further, the axial pawl is set in handwheel inner body wall, and the annular groove is set on valve body.
Further, the driving portion and reversed clamping shaft of forward driving axial direction pawl are provided on the contour curve of the cam
To the card-tight part of pawl.
Further, the lower end of the cam is provided with the planar structure portion that it is rotated about axis convenient for outer power limit.
Further, the both sides radial protrusion of the annular groove forms gear teeth structure, sets on the handwheel inner body wall or valve body
It is equipped with the radial pawl matched with gear teeth structure, the radial direction pawl is alternately distributed with axial pawl.
Further, the radial pawl is set to handwheel inner body wall, and the annular groove and gear teeth structure are set on valve body.
The beneficial effects of the utility model：The utility model is conveniently adjusted the handwheel assembly of scale value direction, when working as scale
When being worth display surface towards user, it can be convenient and quickly adjust so that scale value is towards user；The utility model other
Beneficial effect will be further detailed in conjunction with embodiment in detail below.

Specific embodiment
As shown in the figure：The handwheel assembly for being conveniently adjusted scale value direction in the present embodiment, including being provided with scale value
Handwheel ontology 1 and setting are provided with mutually matched ratchet machine in handwheel intrinsic valve body 2 between handwheel ontology 1 and valve body 2
Structure, the ratchet mechanism include being respectively arranged at handwheel inner body wall with the axial pawl on valve body and for axial limiting axial direction
The annular groove of pawl is provided with below handwheel ontology 1 and is deformed for driving axial pawl to be detached from the cam 4 of annular groove axial limiting,
The cam single-degree-of-freedom is rotationally connected with valve body 2.Valve body inside certain handwheel ontology 1 is provided with spool, valve seat and drive
The driving device etc. that movable valve plug moves up and down, this class formation use the prior art, and details are not described herein again.
It can be with as shown, axial pawl 9 is set on 1 inner wall of handwheel ontology, the annular groove 11 be set to valve body 2
On, naturally it is also possible to axial pawl is arranged on valve body, annular groove is arranged in handwheel inner body wall, is able to achieve practical
Novel purpose；Preferably axially pawl 9 is set on 1 inner wall of handwheel ontology, and the annular groove 11 is set on valve body 2, operation side
Just.
After the installation is completed, axial pawl 9 is stuck in annular groove 11, is only generated axial limiting effect, is had no effect on handwheel ontology
It is rotated around its own axis；When scale value display surface is not towards user, it is fixed, is revolved with the rotation of outer power limit cam 4
Changing hands wheel ontology 1 makes handwheel ontology 1 and cam 4 generate relative motion, and 4 driving axial pawl 9 of cam is close to the change of handwheel ontology 1
Shape after releasing axial limiting, when pulling up the rotation of handwheel ontology 1 after handwheel ontology 1 upwards to towards user, is pressed downward handwheel sheet
Body makes axial pawl 9 continue to be stuck in recovery normal operating conditions in annular groove 11.
In the present embodiment, the driving portion 5 of forward driving axial direction pawl and reversed is provided on the contour curve of the cam 4
The card-tight part 6 of clamping axial direction pawl.When having adjusted scale value towards after restoring normal operating conditions, handwheel ontology 1 is reversely rotated
So that axial pawl 9 is stuck in card-tight part 6, position-limiting action can be played to handwheel ontology 1, it is prevented to be detached from valve body 2.
In the present embodiment, the lower end of the cam 4 is provided with the planar structure portion that it is rotated about axis convenient for outer power limit
7.General operation process manually fixes cam 4 with hand, and fixed cam 4 is convenient in setting planar structure portion 7.
In the present embodiment, the both sides radial protrusion of the annular groove 11 forms gear teeth structure 10, on 1 inner wall of handwheel ontology
It is provided with the radial pawl 8 matched with gear teeth structure 11, the radial direction pawl 8 is alternately distributed with axial pawl 9.Due to the gear teeth
10 both ends of structure are all chamfer bevels, thus no matter forward and reverse rotation handwheel ontology 1, radial pawl 8 all will not be with gear structure
10 is stuck, and only resistance increases when by the double wedge of gear structure, and when by between two adjacent double wedges, resistance subtracts
Small, through this structure, when rotation hand wheel ontology 1, can produce stepping resistance, without seeing that scale can feel handwheel by feel
The case where ontology 1 rotates how many step, understands aperture with feeling.
Certainly, if axial pawl is arranged on valve body, annular groove is arranged when in handwheel inner body wall, corresponding radial direction pawl
It is also disposed on valve body, to prevent axial pawl and radial pawl from interfering with each other.
Finally, it is stated that above embodiments are merely intended for describing the technical solutions of the present application, but not for limiting the present application, although ginseng
The utility model is described in detail according to preferred embodiment, those skilled in the art should understand that, it can be to this
The technical solution of utility model is modified or replaced equivalently, without departing from the objective and model of technical solutions of the utility model
It encloses, should all cover in the scope of the claims of the utility model.
