In the handwheel that is connected, annular magnetic sheet is located at the junction of the square axis of cone and square shaft, and locking axle sleeve is located at square shaft and nibbled with bonnet
Close, nut is located at screw mandrel and is connected with bonnet, and nut interior is machined with raceway and is placed with ball；Bonnet is arranged on valve body
On, the middle and lower part of valve rod is provided with bellows, and bellows is located at the lower section of bonnet and the top of flap, and Step Shaft is used for connection valve
Valve.
Further, the valve body includes upper valve body and lower valve body, and upper valve body and lower valve body are connected by flange, and connection
Place is provided with gasket seal.
The beneficial effects of the present invention are：
(1) present invention instead of traditional slip screw thread by screw mandrel and nut and ball engagement formation rolled threads pair
Pair, can reduce power needed for opening and closing cut-off valve, improve operating efficiency；
(2) present invention is by the cooperation of locking axle sleeve and square shaft, and locking axle sleeve and bonnet are engaged, and have stop valve
There is locking function；
(3) present invention is provided with bellows, buffer fluid medium and valve rod in the middle and lower part of valve rod, reduces temperature to sealing
The influence of filler；
(4) valve body is set to upper valve body and lower valve body by the present invention, is easily installed and replaces bellows.
