Abstract

The invention discloses a liquid level switch and a liquid level control device. The liquid level switch comprises a stationary part (1) and a movable part, wherein the stationary part (1) is provided with a travel switch (11); one of the stationary part (1) and the movable part is provided with a hollow push rod cavity; the other one of the stationary part (1) and the movable part is provided with a push rod (21) capable of moving relative to the push rod cavity in a predetermined range of the push rod cavity; the movable part comprises a floating body (22) capable of floating on the liquid; the movement of the movable part is capable of actuating the travel switch (11). According to the technical scheme, the push rod (21) of the floating body liquid level switch is capable of moving in the predetermined range along the push rod cavity, so that the movement range of the movable part is limited, thereby avoiding shake or swing caused by excessively large movement range of the movable part; the problem that signals shake can be effectively overcome.

Description

technical field [0001] The present invention relates to a liquid level controller, in particular to a liquid level switch, and also to a liquid level control device. Background technique [0002] There are many places in the industrial production process that require liquid level monitoring and automatic control through liquid level controllers, such as waste water pools, sewage pools, slag water pools, and rainwater pools. When the liquid level in the pool reaches the specified level, it needs to be dealt with in time. For example, a liquid level monitor can be used to monitor the liquid level, and when the liquid level reaches the specified liquid level, the monitoring personnel will be reminded to operate to control the liquid level; of course, the pump can also be used in conjunction with the liquid level monitor to realize The liquid level is automatically controlled to maintain the liquid level within a certain range. [0003] Liquid level controllers can be divided ...
