Problems solved by technology

[0004] For now, in the sealing process of existing float valves, the sealing force is mainly provided by the buoyancy of the float, and because the buoyancy provided by the float is limited, the only way to increase it is to increase the volume of the float and adopt a longer connecting rod structure. Sealing force, the structure is relatively complicated; secondly, the opening / closing of the valve is controlled by means of a floating ball and a connecting rod assembly. As long as the fluid medium in the liquid storage device is slightly lost or used, the floating ball valve will open, which will cause the floating ball valve to open. Frequent closing / closing will seriously affect the control of the float switch and the service life of the valve

Embodiment Construction

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0035]It should be noted that when a component is said to be "mounted on" another component, it may be directly on the other component or there may be an intervening component. When a component is said to be "set on" another component, it may be set directly on the other component or there may be an intervening component at the same time. When a component is said to be "fixed" to another component, it may be directly fixed to the other component or there may b...

Abstract

The invention relates to the technical field of valves, in particular to a liquid level controller and a liquid level control system thereof. The liquid level controller comprises a valve body assembly, a valve clack, a valve element, a floating assembly and a differential-type sealing assembly. The valve clack and the valve element are arranged in the valve body assembly; the valve clack and thevalve element are connected, and a cavity is formed between the valve clack and the valve body assembly; a first outlet is formed in the valve body assembly, and a channel is formed in the valve element; one end of the differential-type sealing assembly is used for being matched with the valve element, and the other end of the differential-type sealing assembly is used for being matched with the floating assembly; when bearing force to be upwards floated, the floating assembly pushes the differential-type sealing assembly to seal the channel, and thus the valve clack moves to enable the liquidlevel controller to be stopped; and when the floating assembly falls, the differential-type sealing assembly is separated from the channel, the cavity and the first outlet communicate through the channel, and the valve clack moves to enable the liquid level controller to be started.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a liquid level controller and a liquid level control system thereof. Background technique [0002] The liquid level controller is installed in the liquid storage device to control the liquid level in the liquid storage device. According to different control methods, the liquid level controller can be divided into electronic liquid level switch control and float switch control, that is, float valve, liquid level relay control, non-contact control, etc. The liquid level controller is mainly to control the opening and closing of the valve, so as to replenish the liquid storage device to realize the control of the liquid level. [0003] Float switch control is generally a float valve, which mainly includes valve body components, connecting rod components, and floating balls. The buoyancy drives the floating ball to float to realize the opening / closing of the floating ball valve and ...
