A liquid level controller for vacuum calibrating tank for pipe production

Abstract

The invention provides a liquid level controller for a vacuum calibrating tank for pipe production, which includes a vacuum calibrating tank and a water tank connected thereto. It includes a liquid level control box based on the communication between the water pipe and the inside of the water tank and the same air pressure as the inside. The liquid level control box is located at the same liquid level as the upper limit liquid level and the lower limit liquid level. There are respectively a first float switch and a second float switch. The ball switch is provided with a pipeline solenoid valve on the water inlet pipe, and both the first float switch and the second float switch are electrically connected with the pipeline solenoid valve. The present invention optimizes the design of the liquid level control box communicated with the water tank. Under the condition of ensuring the same internal air pressure of the two, based on the principle of the connector in physics, the liquid levels of the two are always the same. The liquid level can monitor the liquid level in the water tank, which is convenient for observation and later maintenance; the electric automatic control is adopted to improve the monitoring accuracy and ensure the continuous and efficient production of pipes.

Description

technical field [0001] The invention belongs to the technical field of pipe material processing and production, and in particular relates to a liquid level controller for a vacuum calibrating tank used for pipe material production. Background technique [0002] The production and use of pipes have become more and more common in modern economic life. In the processing and production of pipes, the formed pipes need to enter the vacuum calibrating box to be sprayed with water to cool down and set the temperature. The water used for spraying water to cool down is generally stored and circulated by configuring a water tank connected with the vacuum calibrating box. The continuous cooling and shaping processing and production of pipes requires monitoring of the water level in the water tank, that is, when the liquid level in the water tank is lower than a certain threshold, new water needs to be pumped into the water tank; when the liquid in the water tank When the position is hi...

AI Technical Summary

Problems solved by technology

The existing method for mechanically controlling the liquid level of the water tank has at least the following defects: 1. The mechanical control accuracy is low, and the control delay occurs frequently, which affects the high-efficiency continuous production of the pipe material; 2. Since the float switch is set at Inside the water tank, and the huge volume of the water tank will bring a lot of inconvenience to observation and later maintenance
