Substitute valve pressure test fake part

Abstract

The invention relates to the technical field of connecting valves, and discloses a substitute valve pressure test fake part which comprises a connecting pipe, a connecting assembly is arranged on the outer side of the connecting pipe, and a splicing mechanism is arranged on the outer surface of the connecting pipe and located on the side close to the connecting assembly. According to the substitute valve pressure test fake part, the connecting assembly is arranged, the opposite faces of the hubbed butt welding flange and the flat welding flange are attached together in the valve installation process, then the gasket is placed between the hubbed butt welding flange and the flat welding flange, the bolt is twisted to fix the screw rod, and the external thread hose is arranged, when the valve is installed, only the external thread hose needs to be twisted, connection of an outer side pipeline twisted into the flat welding flange is lost, a structure capable of being quickly assembled is adopted, a valve pressure test fake part can be replaced to be used for pressure tests of different pipeline systems, and the valve pressure test device has the advantages of being convenient to carry and disassemble, and capable of being repeatedly used and being used in different chemical projects.

Description

technical field [0001] The invention relates to the technical field of connection valves, in particular to replace valve pressure test dummy parts. Background technique [0002] Instead of valve pressure test fake parts, commonly used workpieces in light industry, chemical industry, petrochemical industry, coal chemical industry, and marine engineering industry, every factory will encounter that the valves purchased by the customer or the factory itself cannot be delivered to the factory during the equipment process. The construction period needs to be in accordance with the plan to install the pressure pipe or the skid block to install the valve under pressure test, and reserve the size and position of the valve in advance. [0003] In the prior art, if the pressure test valve does not arrive at the factory, the delivery date will be affected. The traditional single fixed type is used as the pipeline pressure test part, which is relatively heavy and cannot be reused. It can...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a replacement valve pressure test dummy, which has the advantages of convenient installation, disassembly and repeated use, and solves the problem of the traditional single fixed type, which is bulky and cannot be reused as a pipeline pressure test part. Can be applied to a specific project, new project pressure test has to be re-made, high production cost, waste of materials and labor, long cycle, often requires two people to complete the installation at the same time, disassembly needs to start from the pipe flange, time-consuming, local adjustment lengthy problem
