Description
Technical field
The utility model belongs to valve field.The utility model is suitable for the valve on underwater operation pipeline.
Background technique
It is all the valve rod using elongate valve currently used for the valve on submarine pipeline, extension valve rod easily gets rusty in water,
Open and close torque is big, and valve rod is easy to cause to deform, and valve rod deforms in order to prevent, needs to increase stem diameter, increase product cost and
Volume, installation space are big.
Summary of the invention
The purpose of this utility model is that in view of the problems of the existing technology, it is small to provide a kind of open and close torque, prevents valve rod
It gets rusty deformation, the water proof type that product cost is low, small in size lengthens driving device valve.
The technical solution of the utility model includes valve body, valve rod, driving device；The mainly output axis connection of driving device
Waterproof lengthens transmission mechanism, which lengthens transmission mechanism and be made of bracket and main shaft, and bracket is by steel pipe, upper flange, lower flange
It is formed with sealing cover, deep groove ball bearing is installed between main shaft periphery and upper flange inner hole wall, deep groove ball bearing lower end installation
On the radial convex shoulder of main shaft in plane, seal cap sealing is mounted on the upper surface of deep groove ball bearing and upper flange, in sealing cover
Sealing ring is set between hole and main shaft periphery；Main shaft lower end is equipped with connector sleeve, which is formed with square hole, the square hole and valve rod
The square shaft on top, which cooperates, to be connected；Bearing, lower flange and valve flange are installed at lower flange inner hole and connector sleeve lower end surface
Sealing is fixed.
Preferably, locating shaft is set at main shaft lower end surface center, the setting of valve rod upper surface center cooperates with locating shaft
Location hole.
Preferably, the locating shaft uses square shaft, and the location hole uses square hole.
Preferably, steel bushing is reinforced in welding outside main shaft, which is welded in radial convex shoulder lower plane, adds
Strong steel bushing lower end is welded in connector sleeve upper surface.
Preferably, it is cooperated between reinforcement steel bushing using square shaft and square hole outside main shaft.
The utility model has the advantages that the output shaft in driving device is connect by waterproof lengthening transmission mechanism with valve, subtract
The small design height of valve prevents valve rod infiltration from getting rusty, and valve opening and closing is light, production cost is low, installation space is small.
Detailed description of the invention
