With the matching grooves on valve.
As it is of the present utility model it is a kind of improve, the snap fastener is is arranged on valve circle of position cylinder lateral wall and and valve
On matching grooves tongue, it is preferable that tongue is wholely set with valve circle of position cylinder.Operate it is more convenient, without worry installation or
The loss of valve rod key pin in unloading process.
Further, the valve stem seal of the circular open periphery, which covers, is provided with the sealing drum concentric with circular open, institute
State and annular seal grooves are offered on the lateral wall of sealing drum, elastic seal ring, the sealing ring are provided with the sealed groove
A part exposed outside to sealing drum.
Further, the top of the valve circle of position cylinder is provided with the closure matched with sealing drum, when the closure covers
When on to sealed cylindrical, madial wall and the sealing ring of closure are in close contact.
By the mating reaction of sealed groove, sealing ring and closure, confined space is formed, prevents rainwater etc. from entering valve position
In indicator.
Preferably, the valve stem seal is covered provided with multiple mounting holes, so can be conveniently by bolt by valve stem seal
Lid is installed on valve base.
Preferably, the indicating mechanism is arranged at the top of valve circle of position cylinder, to facilitate monitoring.
Further, the indicating mechanism is three-dimensional arrow, can be conveniently and intuitively right by three-dimensional arrow
Valve position situation is monitored.
Compared with prior art, the utility model has the advantages that：
（1）Simple in construction, convenient disassembly, the maintenance of valve phase indicator and valve member is conveniently；
（2）Valve phase indicator of the present utility model be adapted to it is horizontal and vertical angularly install, strong applicability, the facility of monitoring
Property is good；
（3）Rational in infrastructure, good seal performance and sealing mechanism service life length are dexterously hidden by sealing ring by closure
Ensconce inside valve phase indicator, prevent rainwater and sunlight from being adversely affected to sealing ring, while played a protective role to valve.
