Counter weight for liquid level float switch

Abstract

The invention discloses a counter weight for a liquid level float switch. The counter weight comprises a counter weight cup and a counter weight cover, wherein the top of the counter weight cup is rotatably matched with the counter weight cover; the central part of the counter eight cover is provided with a cover eccentric hole; a cup eccentric hole matched with the cover eccentric hole is arranged in the counter weight cup; at least one filler is arranged around a cup hollow column; the counter weight cover is provided with a rotation handle which is connected with a shell of the counter weight cover; the shell of the counter weight cover is of a layered structure and comprises an indication layer and a connection layer in mutual connection; indication holes are arranged on the part of the connection layer close to the indication layer; the indication layer comprises a start indication layer and a close indication layer corresponding to each other; and the number of the indication holes is two, and the two indication holes are in one-to-one correspondence with the start indication layer and the close indication layer respectively. The counter weight disclosed by the invention notonly is of a simple structure and convenient to use and maintain, but also has relatively good fixing effect and high adjustability.

Description

technical field [0001] The invention relates to a cable fixing device for a float switch, in particular to a weight for a liquid level float switch, and is particularly suitable for a float switch with good fixing effect and strong adjustability. Cable retainer for switch. Background technique [0002] At present, in the hydropower industry, water supply and drainage industry, sewage treatment plant and other industries, liquid level float switches have been widely used, mainly used in water treatment in various industries, clean water pools, mixing pools in waterworks, waste water pools, water intakes, For domestic water tanks and other places that need to automatically monitor the liquid level, the switch can be controlled according to the level of the liquid to achieve the purpose of controlling the automatic start and stop of the water pump. The liquid level float switch is made using the principle of gravity and buoyancy. It is mostly composed of a float and a driving ...
