Description

Technical Field

[0001] The utility model relates to the technical field of valve opening, and particularly relates to a valve opening device. Background Art

[0002] In the current field of mechanical and electrical installation construction, achieving the design requirements is one of the core goals of the project. However, during the ceiling construction near areas such as machine rooms and equipment rooms, a series of thorny problems are often faced. Due to the design layout and functional requirements, the pipelines on the ceilings of these areas are extremely dense. Especially for fire pipelines, they have a large diameter and are equipped with numerous valves, which greatly compresses the operable space in the pipeline concentration area. Moreover, the unique shape design of some decorative secondary keels makes it extremely easy to come into contact with the pipelines below during the installation process, further increasing the complexity and difficulty of construction.

[0003] In the later stage of pipeline construction, during the pressure test and flushing stage, in order to ensure the construction quality and safety, the pressure test construction needs to be carried out separately according to different areas. This requires multiple opening and closing operations of the valves. However, under the existing construction conditions, due to the narrow operation space, complex pipeline layout, and high height, the operation of the valves becomes extremely difficult.

[0004] Traditional valve opening methods and tools are ineffective in such an environment of dense pipelines. They are not only inconvenient to operate, consume a large amount of time, but also usually require working at heights, which is prone to safety problems. At the same time, it will also lead to low construction efficiency and increased construction costs.

[0005] In summary, there is an urgent need for an innovative tool that can simply and conveniently operate valves in dense pipeline areas, avoid working at heights to ensure safety, and save construction time. Content of the Utility Model

A plug capable of being clamped with the valve lock core is arranged at the upper end of the head rod; connecting rings are arranged at the mutually connected ends of the tail rod, the head rod, and the connecting rods. Two adjacent connecting rings are hinged, and the two hinged connecting rings are fixed by fasteners.

[0008] Further, the fastener includes a nut fixedly arranged on an outer side surface of the connecting ring, and a rotating rod is arranged through the center of the connecting ring. One end of the rotating rod is in threaded connection with the nut, and the other end is provided with a rotating handle. Through the rotating handle, the rod bodies after adjusting the length can be preliminarily fastened.

[0009] Further, arc grooves corresponding to each other are formed on one side of the ends where the tail rod, the head rod and the connecting rod are connected to each other. The size of the arc groove is one-fourth of the outer diameter of the connecting ring, and the thickness of the connecting ring is half of the thickness of the rod body where it is located. The connecting ring is fixed in the arc groove, and the other sides of the ends where the tail rod, the head rod and the connecting rod are connected to each other can be abutted against each other, so as to limit the rotation angle of adjacent rod bodies.

[0010] Further, grooves are formed on the side surfaces of the ends where the tail rod, the head rod and the connecting rod are connected to each other and away from the arc grooves. Sliding grooves are formed on the two inner side walls of the grooves at the upper ends of the tail rod and the connecting rod. A rotating shaft is slidably arranged in the sliding grooves, and a hook is vertically arranged on the rotating shaft. A clamping groove matching the hook is formed on one inner wall of the grooves at the lower ends of the head rod and the connecting rod. The free end of the hook can be clamped in the clamping groove. Through the arrangement of the hook and the clamping groove, adjacent two rod bodies can be further fastened and the rotation of the rod bodies can be restricted after the adjacent ends are abutted against each other and preliminarily fastened by the rotating handle.

[0011] Further, an inserting block is fixedly arranged on the bottom surface of the bent section of the hook, and a slot matching the inserting block is formed on the bottom surface of the clamping groove. The inserting block can be inserted into the slot, and the inserting block can prevent the hook from disengaging after hooking the clamping groove.

[0012] Further, a polygonal inserting column is fixedly arranged at the lower end of the plug, and a polygonal slot matching the polygonal inserting column is formed at the upper end of the head rod. A fastening screw is arranged through and in threaded connection with one side wall of the polygonal slot, and one end of the fastening screw located in the polygonal slot can abut against the polygonal inserting column. The plug can be replaced, and a matching plug can be replaced when encountering valve lock cores of different shapes.

[0013] Further, a lock core slot matching the valve lock core is formed on the upper end surface of the plug, and the lock core slot is in a stepped shape that gradually decreases from top to bottom, and can be applicable to valve cores of different models.

[0014] Further, the side surfaces of the tail rod, the head rod and the connecting rod that are close to each other after rotation can be attached to each other, which is convenient for adjusting the length and convenient for storage.

[0015] The beneficial effects of the technical solution provided by the present utility model are as follows: The device can adjust its length according to the height of the pipeline valve through the hinged tail rod, head rod and several connecting rods. After being fixed by fasteners, it can be used to open valves at different heights. This device not only avoids the problem that high-altitude operations are prone to safety accidents, but also can facilitate the operation of valves in dense pipeline areas and save time.
