Description
Technical Field
[0001] The utility model belongs to the technical field of gas transmission pipeline network, and in particular relates to a special adapter for sewage discharge of a trunk cutoff valve. Background Art
[0002] The main shut-off valve is one of the commonly used equipment on the long-distance natural gas pipeline network. A drain plug is set at the drain outlet of the main shut-off valve. Before draining, the drain plug must be disassembled first and then connected to the drain external discharge device. Due to the large size of the drain plug of the main shut-off valve, a pipe clamp is required for disassembly, which is time-consuming and labor-intensive. In addition, since the main shut-off valve is set in the valve pool, the working space is limited and it is inconvenient to use calipers for operation. At the same time, repeated disassembly and installation of the drain plug can easily cause thread damage and damage to the equipment. At the same time, most drain plugs cannot be disassembled through practical operations. At present, two drain holes are set opposite to the drain plug at the end of the main shut-off valve on-site. Adapters are required to drain the two drain holes. Due to the large valve cavity volume and strong airflow impact, there is currently a lack of special drainage parts, which makes the drainage operation more complicated. Utility Model Content

DETAILED DESCRIPTION
[0030] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention. The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. According to the following description and claims, the advantages and features of the present invention will be more clearly described. It should be noted that the drawings are all in a very simplified form and are not in precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.
[0031] like Figure 1-Figure 3As shown, the drain port of the main body of the current main shut-off valve 4 is connected to the drain plug 41 through the drain valve 42. When the drain valve 42 is opened, the main shut-off valve 4 can discharge sewage through the drain hole 411 of the drain plug 41, and when the drain valve 42 is closed, the drain plug 41 cannot discharge sewage. The specific structure of the drain plug is cylindrical, one end of which is connected to the drain valve, and the other end is provided with an internal thread and bolted with a sealing bolt 43 for sealing. Two drain holes 411 are relatively arranged on the side wall of the drain plug. Preferably, the drain hole can be a countersunk hole, and its thick end is located at its outer wall. The drain hole is also arranged along the radial direction of the drain plug.
[0032] like Figure 4 As shown, this embodiment provides a special adapter for draining a main shut-off valve, including an adapter ring 1 and a first adapter 2. The adapter ring 1 is a circular ring, and a threaded hole 11 is radially arranged on its side wall. One end of the first adapter 2 is a plug-in end, and the plug-in end is provided with an external thread that matches the threaded hole 11. The other end of the first adapter 2 is used to communicate with a drainage pipe 3. The adapter ring 1 is used to be sleeved on a drain plug 41 of a main shut-off valve 4, and the threaded hole 11 is connected to the drain hole 4 on the drain plug 41. 11 is aligned, the plug-in end of the first adapter 2 is threadedly connected to the threaded hole 11 and sealed and plugged into the drain hole 411, and is connected to the drain hole 411, so that the adapter ring can be directly sleeved on the drain plug, and the threaded hole is aligned with the drain hole, and then the first adapter is tightened at the threaded hole, so that the plug-in end of the first adapter is sealed and plugged into the drain hole, at this time the first adapter is connected to the drain hole, and the adapter ring is also pinned to the drain plug, and the sewage can be directly discharged through the drainage pipe. The inner diameter of the adapter ring in this embodiment is slightly larger than the outer diameter of the drain plug, so that the adapter ring can be easily sleeved on the drain plug.
[0033] like Figure 5 As shown, in the above technical solution, the plug-in end of the first adapter 2 is coaxially recessed with an annular step-shaped abutment notch 21, and a sealing gasket 22 is sleeved on the abutment notch 21. The end of the plug-in end of the first adapter 2 is inserted into the drain hole 411, and the sealing gasket 22 is pressed against the drain wire plug 41, so that the end of the plug-in end can be inserted into the drain hole, and the sealing gasket can also seal the orifice of the drain hole, which can improve the sealing performance of the first adapter and the drain hole.
[0034] By providing an abutment notch at the end of the plug-in end of the first adapter, a sealing gasket can be sleeved at the abutment notch, and the end of the plug-in end of the first adapter still partially protrudes out of the sealing gasket to communicate with the drain hole. When the drain hole is a countersunk hole, the end of the plug-in end of the first adapter is inserted into the thin end of the drain hole, and the sealing gasket is located in the thick end thereof.
[0035] In the above technical solution, the outer wall of the middle part of the first adapter 2 is a regular hexagon (coaxially distributed regular hexagonal cylinders, similar to the outer edge of a nut), so that the first adapter is easier to tighten or loosen relative to the adapter ring using a wrench.
[0036] The drain wire plug 41 in the above technical solution has two relatively distributed drain holes 411 on its side wall, the adapter ring 1 has two relatively distributed threaded holes 11, and two first adapters 2 are provided, the two first adapters 2, the two threaded holes 11 and the two drain holes 411 correspond one to one respectively, so that the two drain holes can discharge sewage at the same time, and the adapter ring can be more stably pinned to the drain wire plug through the two first adapters.
[0037] In the above technical solution, an elbow 5 is provided at the connection between the other end of the first adapter 2 and the drainage pipe 3. By providing the elbow, the jet discharged from the sewage discharge hole can be buffered to a certain extent by the elbow.
[0038] In the above technical solution, the elbow 5 is connected to the drainage tube 3 via the second adapter 6, so that the elbow can be connected to the drainage tube more conveniently. The elbow is also a metal part, and both ends of the elbow can be provided with internal threads, and the corresponding ends of the first adapter and the second adapter are provided with external threads that match the internal threads on the elbow, so that the first adapter and the second adapter are both threadedly connected to the corresponding ends of the elbow.
[0039] The drainage pipe 3 in the above technical solution includes a main drainage pipe 31, a tee 32 and two branch pipes 33. The two branch pipes 33 correspond one-to-one to the two second adapters 6. One end of each of the branch pipes 33 is connected to the corresponding second adapter 6. One end of the main drainage pipe 31 and the other ends of the two branch pipes 33 are connected through the tee 32, so that the two elbows can share a main drainage pipe, thereby improving the convenience of sewage discharge operation.
[0040] In the above technical solution, a pressure gauge 34 is also provided on the main drainage pipe 31, so that the jet pressure during sewage discharge can be monitored by the pressure gauge.
[0041] In the above technical solution, each branch pipe 33 is also provided with a valve 35, so that the opening of the valve can be adjusted to switch the sewage discharge hole for sewage discharge.
[0042] The main drainage pipe 31 and the branch pipe 33 described in the above technical solution are both flexible and resistant to bending oil delivery hoses (because the stains in the trunk shut-off valve are mostly oil stains, the main drainage pipe and the branch pipe are required to have good oil resistance), and they have good durability.
[0043] The length of the main drainage tube can be about 10 m, which is not specifically limited here.
[0044] The connection between the branch pipe and the second adapter can be a sealed plug-in, and the corresponding end of the branch pipe can be sleeved with a pipe clamp to tighten it to the corresponding end of the second adapter. Of course, the second adapter can also be inserted in the corresponding end of the branch pipe with interference fit, so that the sealing effect is better. Of course, the branch pipe is a soft pipe with a certain expansion and contraction property. In this way, when the second adapter is tightly sleeved on the corresponding end of the branch pipe, due to the expansion and contraction property of the branch pipe, it is tightened on the second adapter and is not easy to loosen.
[0045] In this embodiment, the first adapter, the elbow and the corresponding second adapter are connected as a first integral part, and the three do not need to be disassembled. The drainage tube is a second integral part. When in use, first put the adapter ring on the drainage wire plug, and then assemble the two first integral parts on the adapter ring respectively, and then connect the branch pipe with the corresponding second adapter, and place the drainage end of the main drainage pipe in the collection bucket to start drainage. After the drainage is completed, close the drainage valve, disconnect the two branch pipes from the corresponding second adapter, and then remove the two first integral parts from the adapter ring, and finally remove the adapter ring.
[0046] The above description is only a preferred embodiment of the utility model and does not limit the utility model in any form. Any ordinary technician in the industry can smoothly implement the utility model as shown in the drawings of the specification and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the utility model using the technical content disclosed above are all equivalent embodiments of the utility model. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the utility model are still within the protection scope of the technical solution of the utility model.
