Abstract
The utility mode relates to a valve manual driving device and pertains to the technical field of a valve operation or control device. The technological problem of the utility model to be solved is that a valve manual driving device with low manufacturing cost and long service life is provided. The utility model comprises a fan-shaped worm gear, a spinning hand wheel and a shell. The shell consists of two semi-shells formed by pressing with steel sheet. The two semi-shells are fixedly connected by screws or riveting. The driving device is particularly suitable for being used with such valves as a butterfly valve, a ball valve, a plug valve, etc. the valve cores of which can rotate within the range of 90 degrees.
Description
Technical field
The utility model relates to a kind of valve manual driving device, belongs to valve and handles or the control gear technical field.
Background technique
The valve manual driving device is used for the control of 90 ° of turning valves, as butterfly valve, ball valve, cock etc.Comprise turn handwheel and shell that worm sector, worm transmission pair, worm sector rotation angle are regulated spacing screw rod, linked to each other with worm screw in the formation of existing valve actuator.Shell is made of the housing and the end cap of casting.Its deficiency is the aluminium alloy casting moulding of its housing, and weight is big and heavy, and manufacture cost is higher, and processing technology is complicated.In addition, the intensity of aluminum alloy is lower, and it is unfavorable for improving the working life of valve actuator.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of valve manual driving device, and this installs low cost of manufacture, long service life.
It is as follows to address the above problem the technological scheme that is adopted:
A kind of valve manual driving device, it comprises turn handwheel and the shell that worm sector, worm transmission pair, worm sector rotation angle are regulated spacing screw rod, linked to each other with worm screw, said shell is made of two stamping forming half shells of steel plate, and is fixedly connected between the two halves shell.
Described valve manual driving device is characterized in being fixedly connected as between said two and half shells screw-nut connection or riveted joint.
Valve manual operating device provided by the utility model is the improvement on the original device basis, and original device integral Al-alloy cast housing and end cap are replaced with two and half shells, and half shell is stamping forming with steel plate.Such housing has simple in structure, good manufacturability, and low cost of manufacture, casing rigidity is big, helps improving the working life of device.This device is particularly suitable for and the valve supporting uses of spool angle of revolution in 90 ° of scopes such as butterfly valve, ball valve and cock.
