The invention relates to a novel signal worm gear head. The novel signal worm gear head comprises a shell, a shell cover, a worm gear, a worm and a signal indicator. The worm gear and the worm are inmeshed connection inside the shell. A hand wheel and the portion, outside the shell, of the worm are fixedly installed. The worm gear penetrates out from the shell cover. The top face of the worm gearis flushed with the top face of the shell cover, a chassis is coaxially and fixedly installed at the top face of the worm gear, a limiting sleeve is coaxially and fixedly installed at the top face ofthe chassis, a cam supporting shaft of the signal indicator is inserted into the limiting sleeve, and the signal indicator comprises two cams, the cam supporting shaft, two contact switches, a wiringterminal, an indication dial, an indication dial housing and a circular supporting cover. The circular supporting cover is fixedly inserted between two circles of protrusions manufactured on the topface of the shell cover, and the lower portion of the cam supporting shaft penetrates out from the circular supporting cover to be inserted into a limiting sleeve and fixedly clamped to the limiting sleeve. According to the worm gear head, only several bolts or buckles need to be fixed to the housing, the other bolts or buckles are inserted, operation is easy, and time and labor are saved.
Description
technical field [0001] The invention belongs to the field of valves and relates to a worm gear head, in particular to a novel signal worm gear head. Background technique [0002] The worm gear head is a mechanism that controls the opening of the valve and the flow of the medium. The installation of the traditional worm gear head indicator and the worm gear head housing is cumbersome, and the processing and manufacturing of the worm gear head housing is relatively complicated and the manufacturing cost is high. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a new type of signal worm gear head, which can assemble the worm gear head housing and signal indicator in a short time, is easy to operate, and can be produced in batches during manufacture, reducing the cost of manufacturing. cost. [0004] The technical scheme that the present invention solves technical problem adopts is: [0005] ...
