Description
Technical field
It the utility model is related to ball valve field, more particularly to the upper limit indicating mechanism of ball valve.
Background technology
Ball valve is more frequent in fortune oil pipeline use because it opens and closes quick with accurate, high medium flow efficiency.
The opening and closing instruction of valve is typically determined by handle orientations or executing agency's instruction, but is worked as valve and used too long, related components
After there is abrasion, the problem of position of the switch misregister can be caused, influence valve seal or logical ball cleans.For this reason, it may be necessary to
Outside the on-off structure of top, an accurate club position instruction and position-limit mechanism are redesigned.
Utility model content
In order to solve the above technical problems, the utility model proposes a kind of upper limit indicating mechanism of ball valve, including valve
Bar, support, the support are installed on the adpting flange bottom of valve body, and the valve rod passes through the support, and the valve rod is externally provided with
Actuating sleeve, connecting key is provided between the valve rod and the actuating sleeve, semi-circular shape boss, the driving are provided with the support
Put and be provided with a quarter fan-shaped platform, a quarter sector edge of table is bonded with the plane of the semi-circular shape boss, institute
State support and be provided with peep hole, the peep hole semicircle boss blocks peep hole described in half.
Preferably, the peep hole is two, and described two peep holes are located at the rack side wall, and are separated by 180 °.
The utility model proposes the upper limit indicating mechanism of ball valve have following beneficial effect：Mechanism can accurately refer to
Show the keying position of valve, in the absence of because executing agency's parts depreciation and caused by perform inaccuracy, and then it is actual to influence valve
The situation of keying occurs.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe.
As Figure 1-Figure 4, the utility model proposes a kind of upper limit indicating mechanism of ball valve, including valve rod 1, branch
Frame 6, the support 6 are installed on the bottom of adpting flange 7 of valve body, and the valve rod 1 passes through the support 6, and the valve rod 1 is externally provided with
Actuating sleeve 2, connecting key 4 is provided between the valve rod 1 and the actuating sleeve 2, wherein, connecting key 4 by valve rod 1 and actuating sleeve 2 it
Between connected by connecting key 4, valve rod 1 rotate when, actuating sleeve 2 can be driven while rotated.
It is provided with semi-circular shape boss 3 in the support 6, the actuating sleeve 2 is provided with a quarter fan-shaped platform 8, and described four
The edge of/mono- fan-shaped platform 8 is bonded with the plane of the semi-circular shape boss 3, and the support 6 is provided with peep hole 5, the sight
Examine 5 semicircle boss of hole and block peep hole 5 described in half, a quarter fan-shaped platform 8.
A support 6 is set up below the top of valve rod 1 with executing agency's adpting flange 7, it is semicircle spacing that one is carried in support 6
Block, one actuating sleeve 2 of the top of valve rod 1 connection, the excircle of actuating sleeve 2 carry an a quarter fan-shaped platform 8.Due to ball valve is four/
One Open valve, thus open and close position a quarter sector boss have all the time side touch it is semicircle convex in support 6
Platform.Cylindrical 180 ° of the interval of support 6 is provided with two peep holes 5, when it is a complete circle to see in hole, illustrates that valve is in out
Open/closed position.
A variety of modifications to embodiment will be apparent for those skilled in the art, determine herein
The General Principle of justice can be realized in other embodiments in the case where not departing from spirit or scope of the present utility model.Cause
This, the utility model is not intended to be limited to the embodiments shown herein, and is to fit to and principles disclosed herein
The most wide scope consistent with features of novelty.
