Description

Liquid level float control device

technical field

The utility model relates to a liquid level floating ball control device.

Background technique

In some production equipment, a kind of liquid storage tank is often involved. The liquid in the liquid storage tank needs to be continuously supplied to the next equipment, so as to ensure the normal operation of the next equipment. To ensure the continuous supply of energy in the liquid storage tank For the next equipment, the liquid in the liquid storage tank needs to be guaranteed. At this stage, the liquid volume in the liquid storage tank is mainly ensured manually. If the liquid in the liquid storage tank is found to be insufficient, the personnel will add liquid to the liquid storage tank. Manually Predict the liquid required by the equipment and add it, so as to ensure that the liquid in the liquid storage tank is not wasted, but this increases the workload of the personnel. If the personnel fail to find out that the liquid in the liquid storage tank needs to be added in time, it will affect the follow-up work. process, greatly reducing work efficiency.

Contents of the invention

In order to overcome the above disadvantages, the purpose of this utility model is to provide a liquid level float control device that can automatically control the opening or closing of the water inlet pipe.

In order to achieve the above purpose, the technical solution adopted by the utility model is: a liquid level float control device, which includes a barrel body, a water inlet pipe with a water inlet solenoid valve arranged at the upper end of the barrel body, and a water inlet pipe arranged at the upper end of the barrel body. There is a water outlet at the lower end of the barrel body, and an induction connecting rod is also provided in the barrel body, and the induction connecting rod has a first induction contact, a second induction contact and a liquid sleeve set on the induction connection rod. Level float, the water inlet solenoid valve and the induction connecting rod are connected in the electric control cabinet through wires, when the liquid level float floats up to the first sensing contact, the first sensing contact sends a The stop signal is sent to the electric control cabinet, and the electric control cabinet controls the closing of the water inlet solenoid valve; when the liquid level float floats down to the second sensing contact, the second sensing contact sends an opening signal To the electric control cabinet, the electric control cabinet controls the opening of the water inlet solenoid valve.

Preferably, the liquid level float floats up to the first sensing contact when the liquid in the barrel rises, and the liquid level float floats down to the first sensing contact through the drop of liquid in the barrel. Second sense contact.

Preferably, the density of the liquid level float is smaller than that of the liquid, so as to ensure that the liquid level float can float on the liquid.

Due to the adoption of the above technical scheme, it is not difficult to see that the liquid level float control device of the utility model floats up to the first sensing contact and the second sensing contact through the liquid level float to control the closing and closing of the water inlet solenoid valve on the water inlet pipe. Opening, through automatic control of the liquid in the barrel, compared with the traditional scheme of manually controlling the liquid in the barrel, it reduces the workload of personnel and avoids the problem of affecting the operation of subsequent equipment due to personnel failing to fill the barrel with liquid in time ,Improve work efficiency.
