Prefabricated valve set for four-pipe fan coiler

Abstract

The invention provides a prefabricated valve set for a four-pipe fan coiler. The prefabricated valve set comprises a support, an electric two-way valve, a first ball valve, a second ball valve and a filter. The support comprises a steel channel, first supporting plates and second supporting plates. Multiple first supporting plates are fixedly connected to the outer side of the first side wall of the steel channel. Multiple second supporting plates are fixedly connected to the outer side of the second side wall of the steel channel. The first side wall and the second side wall are parallel. Thefirst end of the electric two-way valve is connected with the first end of the first ball valve through a first pipe section. The first end of the filter is connected with the first end of the secondball valve through a second pipe section. The first pipe section penetrates through holes in the first supporting plates, and the second pipe section penetrates through holes in the second supportingplates. According to the prefabricated valve set, the project construction quality is improved greatly, the prefabricated valve set has integrality and compactness, and is easy to install, and unnecessary potential safety hazards of high-altitude operation are avoided.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a four-pipe fan coil prefabricated valve group. Background technique [0002] In various public mechanical and electrical projects, especially those with higher requirements for the air-conditioning system, the fan coil in the air-conditioning system generally adopts four-pipe connection pipes, and uses separate cold and hot water supply pipes and return pipe systems, which can be integrated in one In the season, the room is cooled or heated separately, which increases the flexibility of the air conditioning system adjustment. There are a series of valve parts when connecting with the fan coil unit, which makes the mechanical and electrical construction more complicated and cumbersome, and increases the construction and installation time. How to find a simple way to improve the construction and installation efficiency is the subject of this invention. [0003] The exist...
