Description

Technical Field

[0001] The utility model relates to the technical field of design and manufacturing of turbine flowmeter maintenance tools, and more specifically, to a Y-shaped gland wrench for turbine flowmeter maintenance. Background Art

[0002] A Y-type gland wrench is a hand tool with a unique design that features two or more branches, shaped like the letter "Y." This type of wrench is typically used to tighten or loosen fasteners with glands that may be located in hard-to-reach or space-restricted areas. During use, turbine flowmeters require regular maintenance and inspection due to fluid impact, deposition of impurities, and wear of mechanical components. The quality of maintenance work directly affects the performance and life of the turbine flowmeter. Improper maintenance may lead to decreased measurement accuracy, frequent failures, and even affect the metering accuracy of the flowmeter. When disassembling and maintaining a gas turbine flowmeter for inspection and cleaning, the gland is generally difficult to remove; if disassembled violently, the gland gasket may be deformed or damaged, affecting the sealing performance and causing the flowmeter to malfunction and leak.

Under the action of the No. 2 spring 22, the adjusting block 21 enters the pin hole 29 on the surface of the wrench inner rod 1. The movement of the connecting rod 18 drives the No. 2 gear 27 to move, the rack 24 is fixed, and the No. 2 gear 27 is engaged with the rack 24, which will drive the rectangular block rack 26 to move outward, and the rectangular block rack 26 drives the wrench inner rod 1 outward.

The No. 1 gear 4 contacts the ratchet 7 above the ratchet 5 to achieve clockwise rotation, completing the disassembly of the turbine flowmeter gland.

[0025] Through the design of gear No. 1 4, ratchet 5 and ratchet 7, the Y-type gland wrench device 10 is aligned with the gland of the turbine flowmeter, a specific square block is inserted into the square slot 6, the ratchet 5 is rotated to rotate the right side of the ratchet 5 upward, and the inner rod 1 of the wrench is rotated clockwise. Since the Y-type gland wrench device 10 is used to clamp the gland of the turbine flowmeter, the inner rod 1 of the wrench will drive the rotating shaft 9 to rotate, and the rotating shaft 9 drives the No. 1 gear 4 to rotate. The No. 1 gear 4 contacts the ratchet 7 above the ratchet 5 to achieve clockwise rotation, completing the disassembly of the gland of the turbine flowmeter, and rotating the inner rod 1 of the wrench counterclockwise will not generate resistance.

Since the Y-type gland wrench device 10 is used to clamp the turbine flowmeter gland, the wrench inner rod 1 will drive the rotating shaft 9 to rotate, and the rotating shaft 9 drives the No. 1 gear 4 to rotate.
