Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of splint valves, in particular to a reduced-diameter connection structure of a splint valve. Background Art
[0002] The splint valve is an important supporting device in the technology of non-stop pressure pipeline tapping. Its performance directly affects the implementation effect of the pressure pipeline tapping operation. When in use, the splint valve is installed on the plugging tee on the pressure pipeline to hold the tapping machine for pressure pipeline tapping, or install the plugging device to plug the pressure pipeline, so as to complete the pipeline emergency repair construction and other operations. Usually, the models of the tee, the tapping machine, and the plugging device should be the same to ensure good sealing of the connection surface. However, the price of the splint valve is relatively expensive, and there is often a shortage of spare parts in emergency repair construction, which either affects the smooth progress of the construction or greatly increases the economic cost of the emergency repair. Summary of the Invention
[0003] In order to solve the above problems, the utility model provides a reduced-diameter connection structure of a splint valve, and the following specific technical solutions can be adopted:
[0004] The reduced-diameter connection structure of the splint valve described in the utility model is arranged between the splint valve and the pipeline tee, the tapping machine and / or the plugging device, and includes a transition section. One end of the aperture of the transition section is adapted to the splint valve, and the other end is adapted to the pipeline tee, the tapping machine or the plugging device; counterbored through holes and threaded blind holes are arranged around the aperture of the transition section. A first connecting bolt extending from the transition section to the splint valve is arranged in the counterbored through hole, and a second connecting bolt extending from the pipeline tee, the tapping machine or the plugging device to the transition section is arranged in the threaded blind hole; a concentric annular concave-convex structure is arranged on the connection surfaces of the transition section with the splint valve, the pipeline tee, the tapping machine, and the plugging device, and metal gaskets are arranged on the connection surfaces of the transition section with the splint valve, the pipeline tee, the tapping machine, and the plugging device.
[0005] The counterbored through holes are arranged outside the threaded blind holes, and adjacent counterbored through holes are evenly spaced circumferentially, and adjacent threaded blind holes are also evenly spaced circumferentially.
[0006] The concentric annular concave-convex structure is arranged on the connection surface inside the counterbored through hole.
[0007] The reduced-diameter connection structure of the splint valve provided by the utility model has a clever structure, low cost, convenient installation, firm connection, and good sealing. It can overcome the defect that the splint valve does not match the models of the tee, the tapping machine, and the plugging device, and realizes that one splint valve can be simultaneously matched with multiple models of equipment to meet the requirements of emergency repair construction, speeds up the project progress, and reduces the construction cost.
[0008] Compared with the prior art, the advantages of the utility model are as follows:
[0009] 1) The structure of the present utility model has been greatly improved. Under the limitation that the original conventional splint valve can only be used in a single supporting manner, by adding transition joint devices at one end or both ends of the splint valve, using bolts to tightly connect the splint valve with other devices, and using countersunk through holes to prevent the bolts from being higher than the connection surface, the purpose of not affecting the sealed connection between the transition joint and other devices is achieved. Thus, the splint valve and related equipment can be quickly installed according to the diameter of the main pipeline during emergency repair construction, avoiding the delay of the construction period.
[0010] 2) The present utility model connects the splint valve, the transition joint and other equipment through bolts. In order to eliminate the safety hazards caused by poor sealing performance, a concentric annular concave-convex structure is set on the transition joint, and a metal gasket is installed on the connection surface, thereby obtaining a good sealing structure and enabling it to be used in the operating conditions of continuous operation under pressure.
[0011] 3) By using transition joints with unequal diameters at both ends, the present utility model changes the drawback that the splint valve cannot be matched with a variety of equipment, meets the requirements of emergency repair construction, and reduces the construction cost. BRIEF DESCRIPTION OF THE DRAWINGS
[0012] Figure 1 is a schematic structural diagram of the present utility model. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0013] The following will describe the embodiments of the present utility model in detail with reference to the drawings. This embodiment is implemented on the premise of the technical solution of the present utility model, and the detailed implementation manners and specific working processes are given. However, the protection scope of the present utility model is not limited to the following embodiments.
[0014] As Figure 1 shown, the variable-diameter connection structure of the splint valve described in the present utility model can be arranged between the splint valve M and the pipe tee T, or can be arranged between the splint valve and the M hole opener P or the plugging equipment, and can be specifically determined according to the on-site working conditions.
[0015] Whether installed at one or both ends of the clamping plate valve, it is achieved through the transition section 1. Specifically, one end of the aperture of the transition section 1 is adapted to the clamping plate valve M, and the other end is adapted to the pipe tee T, the hole opener P or the plugging device. Countersunk through holes 2 and threaded blind holes 3 are provided around the aperture of the transition section 1, and the countersunk through holes 2 and the threaded blind holes 3 are respectively arranged along concentric rings of unequal diameters. The countersunk through holes 2 are on the outer ring, and the threaded blind holes 3 are on the inner ring. Adjacent countersunk through holes 2 are evenly spaced circumferentially, and adjacent threaded blind holes 3 are also evenly spaced circumferentially. A first connecting bolt 4 extending from the transition section 1 to the clamping plate valve M is provided in the above-mentioned countersunk through hole 2, and a second connecting bolt 5 extending from the pipe tee T, the hole opener P or the plugging device to the transition section 1 is provided in the threaded blind hole 3. In order to improve the sealing performance between the connection surfaces, a concentric annular concave-convex structure located inside the countersunk through hole 2 is provided on the end surface of the transition section 1, and a metal gasket 6 is installed on the connection surfaces of the transition section 1 with the clamping plate valve M, the pipe tee T, the hole opener P and the plugging device.
[0016] It should be noted that in the description of the present invention, terms indicating orientation or positional relationships such as "front", "rear", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation to the present invention.
