The second sealing ring 20 is embedded with recessed channel 19.First sealing ring 18 and the second sealing ring.20 prevent the liquid such as rainwater from entering activity
In hole 10 so that spring 12, connecting rod 11 and alignment pin 8 will not corrosion, extend spring 12 service life, facilitate secondary tear open
Unload.
As shown in figure 1, handwheel 1 and valve rod 2 only bear moment of torsion by alignment pin 8 due to handwheel 1 in use
When, easily make the secondary dismounting of the deformation effect of alignment pin 8.Therefore, mounting hole 5 is in kidney-shaped, and the side wall of mounting hole 5 is divided into the He of straightway 51
Segmental arc 52, positioning hole 6 are located in the side wall of the straightway 51 of mounting hole 5.When rotating handwheel 1, valve rod 2 will not with installation portion 4
Generation radial rotating, the moment of torsion that alignment pin 8 is born is reduced, avoids alignment pin 8 from bearing moment of torsion for a long time and deform.
As shown in figure 5, being deformed to prevent alignment pin 8 from bearing the gravity of handwheel 1 for a long time, valve rod 2 includes construction section 201
With cylindrical portion 202, construction section 201 is in kidney-shaped and, cylindrical portion 202 and construction section 201 junction identical with the shape size of mounting hole 5
A supporting table 15 is formed, the bottom face of installation portion 4 abuts with supporting table 15.Because the bottom face of installation portion 4 abuts with supporting table 15, hand
The gravity of wheel 1 is born by valve rod 2, and alignment pin 8 only plays positioning action, therefore does not allow yielding.
Working principle and beneficial effect of the present utility model is as follows：
When needing to dismantle handwheel 1 and valve rod 2, by pull operation end 14, operating side 14 is driven by connecting rod 11 and positioned
In the retraction movable span 10 of 8 compression spring of pin 12, so as to which Rapid reversal is to the spacing of valve rod 2, handwheel 1 is removed., will during installation
Valve rod 2 is provided with the mounting hole 5 of one end insertion handwheel 1 of through hole 7, is made through hole 7 conllinear with the axial line of positioning hole 6, is unclamped operation
End 14, the elongation of spring 12 drive alignment pin 8 to insert in through hole 7, completed to the spacing of valve rod 2, due to need not be by other works
Tool, convenient disassembly.
Because reinforcement 3 is obliquely installed so that installation portion 4 and handwheel 1 in the same plane, do not increase operating space,
During disassembly and installation handwheel 1, facilitate operating personnel's pull operation end 14.
After the deformation of alignment pin 8, pull down alignment pin 8 and pass through manhole 16, so as to change alignment pin 8, maintenance
It is convenient.After spring 12 produces metal fatigue and failed, operating side 14 is pulled down, connecting rod 11, alignment pin 8 are taken out from manhole 16
It is easy to maintenance so as to change spring 12 with spring 12, improve follow-up dismounting convenience.
Described above is only preferred embodiment of the present utility model, and the scope of protection of the utility model is not limited merely to
Above-described embodiment, all technical schemes belonged under the utility model thinking belong to the scope of protection of the utility model.It should refer to
Go out, for those skilled in the art, some improvement under the premise of the utility model principle is not departed from and
Retouching, these improvements and modifications also should be regarded as the scope of protection of the utility model.
