Description
Technical field:
The utility model relates to rotate the valve of class folding, in particular to a kind of rotation class valve with installation position limiting structure
Door.
Background technique:
For soft sealing butterfly valve, the valve of the rotation class folding such as the butterfly valve that does not limit and ball valve, when in-site installation finds, when
When valve is attached on pipeline 91, valve plate can be can't see or the centre of sphere is on or off, only in the corresponding valve connected with actuator
Have a groove 93 on 92 top surface of axis judge valve plate or the centre of sphere where.Fig. 1~3 are respectively that valve is in off-position, half
Open position, the state of open position, when without actuator, worker can rotate valve shaft 92 with spanner come after test line 91 and valve installation
Whether seepy question, for the valve not limited, perhaps valve shaft 92 can go to the position for holding position or Guan Guowei, such one
Come, when actuator is installed, if the not corresponding installation in position, will cause actuator cannot well control valve to standard-sized sheet/
Closed positions, or even cause switch reversed.In addition, upper lower flange is opposite when actuator is installed, it can be the valve between them
Axis groove 93 blocks, and causes the difficulty accurately installed.
Summary of the invention:
In consideration of it, it is necessary to design one kind can limiter valve turned to ON/OFF position and can effectively indicate installation position
The rotation class valve with installation position limiting structure set.
A kind of rotation class valve with installation position limiting structure, comprising: valve body, spool, flange, valve shaft；Wherein, spool position
In in valve body, spool realizes conducting/sealing of valve by the rotation of its own, and flange is located at body top, valve shaft one end and
Spool connection, the valve shaft other end are pierced by flange and drive valve core rotation by own rotation to connect actuator, valve shaft；It has
The rotation class valve of installation position limiting structure further includes limit pointer, is vertically provided with one 1/4 on the end face of flanged joint actuator
Round through slot, and fan-shaped region is surrounded by circular arc using 1/4 circle through slot on the same end face of flange and mills out a groove, it is described
The start-stop position of 1/4 circle through slot respectively corresponds the standard-sized sheet and closed positions of spool；Limit pointer need to have certain rigidity, and limit refers to
Needle includes leading portion, middle section and back segment, and back segment is located in the groove, and back segment one end is fixed with valve shaft, and the other end is vertical with middle section
Fixed, middle section is pierced by downwards by the 1/4 circle through slot, and middle section lower end is vertical with leading portion to be fixed, and the leading portion other end is to flange outside
It stretches out, the axis co-planar of plane and valve shaft where limit pointer, the junction for limiting pointer and valve shaft makes to limit pointer by institute
Spool is exactly in standard-sized sheet/off position when stating 1/4 circle through slot limit.
Preferably, orthographic projection of its axis of the pipeline being connect with valve on the end face of flanged joint actuator, and it is described
1/4 circle through slot one end is overlapped.
Preferably, when plane where limit pointer is vertical with the orthographic projection, spool is exactly in closed positions.
The utility model is in installing the debugging before actuator, since 1/4 circle through slot is to the position-limiting action for limiting pointer, valve
Door, which will not be transferred to, to be opened or crosses off position, and easily reaches standard-sized sheet/off position, is avoided valve and is in/the open position that reaches a standard
Set the problem of connecting with actuator；Simultaneously as limit pointer front end will not be blocked when installing actuator, thus
Be conducive to actuator accurately to install.

In figure:
The prior art: pipeline 91, valve shaft 92, groove 93.
The utility model: valve body 1, flange 3, valve shaft 4, limit pointer 2, through slot 31, groove 32, leading portion 21, middle section 22, after
Section 23, pipeline 5.
Specific embodiment:
As shown in Figure 4,5, a kind of rotation class valve with installation position limiting structure, comprising: valve body 1, spool, flange 3, valve
Axis 4；Wherein, spool is located in valve body 1, and spool realizes conducting/sealing of valve by the rotation of its own, and flange 3 is located at valve
Also integrally casting shaping can be bolted in 1 top of body, flange 3 and valve body 1, and 4 one end of valve shaft is connect with spool, valve shaft 4
The other end is pierced by flange 3 and drives valve core rotation by own rotation to connect actuator, valve shaft 4, and valve internal is more specific
Structure be the prior art, be not repeated herein；Rotation class valve with installation position limiting structure further includes limit pointer 2, method
The through slot 31 of one 1/4 circle is vertically provided on the end face of 3 connection actuator of orchid, and logical with 1/4 circle on the same end face of flange 3
Slot 31 surrounds fan-shaped region by circular arc and mills out a groove 32, and the start-stop position of the 1/4 circle through slot 31 respectively corresponds spool
Standard-sized sheet and closed positions；Limit pointer 2 need to have certain rigidity, and limit pointer 2 includes leading portion 21, middle section 22 and back segment 23,
Back segment 23 is located in the groove 32, and 23 one end of back segment and valve shaft 4 are fixed, other end fixation vertical with middle section 22, middle section 22 by
The 1/4 circle through slot 31 is pierced by downwards, the fixation vertical with leading portion 21 of 22 lower end of middle section, and 21 other end of leading portion is to stretching on the outside of flange 3
Out, the junction of the axis co-planar of the plane where limit pointer 2 and valve shaft 4, limit pointer 2 and valve shaft 4 makes to limit 2 quilt of pointer
Spool is exactly in standard-sized sheet/off position when the 1/4 circle through slot 31 limits.
In the present embodiment, its axis of pipeline 5 connecting with valve connects the positive throwing on the end face of actuator to flange 3
Shadow, the orthographic projection are overlapped with 1/4 circle, 31 one end of through slot, i.e., are overlapped with the endpoint of 1/4 circular arc.
In the present embodiment, when limit 2 place plane of pointer is vertical with the orthographic projection, spool is exactly in full off-position
It sets.
