Three-way electric valve union disassembling tool and suit

Technical Field

The utility model relates to an air conditioning system overhauls technical field, especially relates to a tee bend motorised valve union disassembly and assembly tool and suit.

Background

The special precision air conditioner for the machine room is a special technical air conditioner designed for a modern electronic equipment machine room, because computer equipment, a program controlled switch product and the like in the machine room are composed of a large number of electronic elements, the stability and the reliability of the use of the equipment are improved, the temperature and the humidity of the environment are strictly controlled within a specific range, the common air conditioning equipment cannot meet the high-precision temperature and humidity regulation and control requirements of related equipment, and the special precision air conditioner for the machine room can control the temperature and the relative humidity of the machine room within a very small fluctuation range, so the service life and the reliability of the equipment are greatly improved.

The three-way electric valve is an important part of a special precise air conditioner for a machine room, and the cold water flow regulated by the three-way electric valve provides precise control for the conditions of the machine room. As shown in fig. 4, the three-way electric valve 5 is connected with the pipeline 7 through a movable joint 6 in use, one end of the movable joint 6 is connected with an internal thread at the end part of the three-way electric valve 5 through an external thread, the other end of the movable joint 6 is butted with the pipeline, both of the movable joint and the pipeline are provided with external threads and connected through an internal thread locking nut, and a strip-shaped positioning clamping point 61 (see fig. 5) is arranged on the inner wall of the pipeline connecting end of the movable joint 6. When the three-way electric valve 5 needs to be repaired or replaced, the movable joint 6 needs to be detached from the three-way electric valve 5. Since the union 6 is connected to the three-way electric valve 5 by a screw, a common way of disassembling at present is to clamp the union 6 from the outside by a pipe wrench and unscrew it from the three-way electric valve 5. However, the movable joint 6 is often damaged and cannot be reused.

Detailed Description

It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict. The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

Fig. 1-3 show an embodiment of the three-way electric valve union disassembling tool of the present invention. In this embodiment, the three-way electric valve union detaching tool includes a cylindrical main body 1, a stopper plate 2, and a force application portion 3. One end of the cylindrical main body 1 is a free end, the other end of the cylindrical main body is fixedly connected with the limiting plate 2, and the diameter of the limiting plate 2 is larger than that of the cylindrical main body 1. The stopper plate 2 is connected to the urging portion 3 on the opposite side to the side connected to the cylindrical body 1. The biasing portion 3 is used for biasing a tool such as a wrench. At least one pair of clamping grooves 4 are formed in the outer wall surface of the cylindrical main body 1, the two clamping grooves 4 in the pair of clamping grooves 4 are symmetrically arranged, and the two clamping grooves all extend to the free end of the cylindrical main body 1 along the axial direction.
