Pipeline anti-freeze drainer and application method thereof

Abstract

The invention discloses a pipeline anti-freeze drainer and a method. The pipeline anti-freeze drainer is characterized in that the pipeline anti-freeze drainer comprises a bleeder valve comprising a jacket; a piston is arranged at the upper portion of the inner wall of the jacket in a matched manner, a pressure adjusting nut is in threaded fit with the lower portion of the inner wall of the jacket and is provided with through holes for emptying; springs are arranged between the pressure adjusting nut and the piston; an inner ring used for being matched with the bottom face of the piston and used for limiting is arranged on the inner wall of the jacket and above a pressure adjusting bolt; a connecting discharging port communicated with an inner cavity of the jacket is formed above the inner ring and on the wall of the jacket; a connector is arranged and connected with the discharging port; the pipeline anti-freeze drainer further comprises a release control valve, one end of the release control valve is communicated with a pipeline, and the other end of the release control valve is communicated with the connector; and the upper end of a release valve is communicated with the pipeline after being connected with a control valve. Compared with the prior art, the purpose of draining accumulated water in the pipeline when the water conveying pipeline is shut down and overhauled in severe cold weather is achieved. It is prevented that the additional maintaining cost is increased after the pipeline is frozen damaged, the labor intensity of workers is relieved, the operation risk is reduced, and the overhauling time is saved.

Description

technical field [0001] The invention relates to a pipeline antifreeze drainer and a use method thereof. Background technique [0002] In modern industry, there is no industrial sector that does not use water, and there is no industry that does not have a direct or indirect relationship with water. More industries use water to cool equipment or products. Every factory uses water for various functions. To maintain normal production, antifreeze of water pipes is also a very tricky part of daily work. [0003] In order to prevent the stagnant water in the pipeline from freezing and damaging the pipeline in the severe cold season, two solutions are generally adopted: [0004] One is to add insulation material to the outside of the pipeline, which can keep the water temperature in the pipeline above the freezing point in a short period of time, and prevent the volume from expanding and tearing the pipe wall after the water freezes. If the water in the pipeline does not flow for a...

AI Technical Summary

Problems solved by technology

[0008] In order to solve the above problems, the present invention provides a pipeline antifreeze drain and its use method. By setting the drain valve, the problem of water accumulation inside the discharge pipeline when the water pipeline is out of service for maintenance in severe cold weather is solved, and at the same time, the pipeline is prevented from being damaged by freezing. Additional maintenance costs will be added later, which reduces the labor intensity and operation risks of personnel, and saves maintenance time
