Abstract
Description
Technical Field
[0001] This invention relates to a heat preservation box for pipe bundles in steam tracing and drain valve stations, which is used in steam distribution stations and drain valve stations of steam tracing pipeline networks to provide box-type insulation for the pipe bundles in drain valve stations. Background Technology
[0002] Currently, the insulation of traditional steam tracing and drain valve station pipe bundles is done on-site. Each distribution pipe valve and drain valve is individually packaged and insulated. The workload of insulating many branch valves and drain valves in the entire pipe bundle is very large. The space is very small, and it is not easy to do insulation. Manual packaging is also very messy and unsightly. This is a problem in the installation of piping in engineering projects. Summary of the Invention
[0003] The technical problem this application aims to solve is: addressing the difficulties of on-site packaging for steam tracing steam trap station pipe bundle insulation, which involves a large workload, limited space, and is difficult to perform insulation work properly, resulting in an unsightly appearance. This application provides a steam tracing steam trap station pipe bundle insulation box, which houses the entire steam tracing steam trap station pipe bundle. The insulation box provides overall insulation for the pipe bundle. The insulation box has a movable door, allowing for easy opening and operation of valves, as well as maintenance and replacement of steam traps, without the need to disassemble the insulation sleeve.
[0004] To address the aforementioned issues, this application is characterized by the following: Based on the number, size, and spatial distance of valves in the steam tracing and drain valve station pipe bundle, and according to the external dimensions (length x width x thickness), plus the insulation layer thickness and valve operating space, steel plate sandwich insulation boxes of different specifications and sizes are designed. The insulation box is divided into two separate insulated halves, separated by the middle. The rear half has a sealed bottom, and 30cm of insulation cotton is installed around its perimeter. The front half has an insulated door with hinges and a lock, and 30cm of insulation cotton is also installed around its perimeter. The inside and outside of the insulation box are made of 1mm thick galvanized steel plates, with 30mm of insulation cotton installed in the middle. Based on the external dimensions of the box, a 40mm x 40mm angle steel edging bracket is constructed at the four corners of the exterior and the four corners of the rear perimeter of the insulation box. Two 40x80x40 channel steels are welded to the center of the upper and lower sides of the angle steel bracket. The small plane of the channel steel is aligned with the middle connecting edge of the rear half of the box. The prefabricated rear half of the insulation box is placed into the angle steel bracket. The four corners and the perimeter of the rear half of the box are fixed to the angle steel bracket with self-drilling screws. Then, the pipe bundle with the drain valve installed is placed into the rear half of the insulation box. Two bolt holes are drilled in the middle of the channel steel. The recovery main pipe of the pipe bundle is locked to the two channel steels above and below the angle steel bracket with pipe clamp bolts, so that the entire drain valve station pipe bundle is suspended in the middle of the insulation box. After the drain valve station pipe bundle is installed and locked, the front half of the insulation box is aligned with the four corner brackets of the box and merged with the rear half of the box. The front half of the box is fixed to the angle steel at the four corners with self-drilling screws, and then merged into a complete insulation box.
[0005] Before merging, the front half of the box is aligned with the outlet of the main recovery pipe and the branch pipe of the condensate station, and outlet channel openings are reserved for both. There are 4 bolt holes drilled behind each of the two channel steels on the upper and lower parts of the insulation box support for external connection and installation of the insulation box. There is a movable box door in front of the insulation box. During production, workers can open the insulation box door at any time to operate the valve switch and inspect the condensate valve. The external connection of the condensate inlet of the condensate station pipe bundle adopts flange connection and compression fitting movable joint for easy maintenance and replacement of valves.
[0006] This application aims to provide users with a steam tracing condensate valve station pipe bundle insulation box that meets the usage requirements of the steam tracing condensate valve station pipe bundle. The advantages are that the insulation box is neat and beautiful, windproof and rainproof, dustproof and fireproof, with good overall insulation effect, convenient operation of valve opening and closing, and easy maintenance and replacement of condensate valves, saving on-site installation time and improving work efficiency.
