Problems solved by technology

In the construction of large-scale projects, due to the large number of fire protection zones, large systems, concentrated risers and large water volume in the pipe network, if the traditional suppression method is adopted, it will lead to high labor intensity, long water injection time, long suppression time, low efficiency and design changes Pipeline repressurization is slow
When faced with the situation of tight construction schedule and strict cost control, there is an urgent need for a new pressure device and pressure method to solve the problem of low efficiency of single pipeline pressure test, improve pipeline pressure efficiency, reduce pressure test cost, shorten pipeline pressure test time, and achieve Duration Node Requirements

Abstract

The invention relates to an environment-friendly integral pipeline pressing device and a pressing method. The pressing working condition and the water changing working condition are efficiently and rapidly switched through a second branch pipe which is arranged and a water injection valve and a pressing valve located on the second branch pipe. Switching of the valve meets design changes, etc., andresults in a retest pressure. The operation is very flexible and convenient. The efficiency can be greatly improved, and the pressing progress is accelerated by about 50% through a number of first branch pipes which are arranged. The pressing time and the pressing labor can be saved, the pressure test cost is reduced, and the construction period requirement is guaranteed by using the pressing method of the pressing device. The method is applied to the field of mounting and pressure test of the pipeline in building construction.

Description

technical field [0001] The invention relates to the technical field of pipeline installation and pressure testing in building construction, in particular to an environment-friendly integrated pipeline compression device and a compression method. Background technique [0002] In the field of building construction, it is an indispensable work to carry out liquid pressure test on fire pipelines. The traditional pressure test technology uses plastic hoses to connect the pressure test pipeline and the water point of the civil construction, uses a pressure pump to inject water and pressurize, and repeats the operation one by one to complete the pressure test. In the construction of large-scale projects, due to the large number of fire protection zones, large systems, concentrated risers and large water volume in the pipe network, if the traditional suppression method is adopted, it will lead to high labor intensity, long water injection time, long suppression time, low efficiency ...
