Description

Technical Field

[0001] This utility model relates to the field of mud gate valve technology, and in particular to a mud gate valve that is easy to replace. Background Technology

[0002] Mud gate valves are divided into two types: steel-core mud gate valves and rubber-core mud gate valves. They are mainly used for cutting off the medium in drilling mud manifolds during oil and gas extraction.

[0003] When existing mud gate valves are damaged and need to be replaced during use, the mud system often needs to be shut down before the valve can be replaced, which is very inconvenient and will affect the progress of the project. Therefore, a mud gate valve that is easy to replace is proposed. Utility Model Content

[0004] The main purpose of this utility model is to provide a mud gate valve that is easy to replace. The mud is stopped by the second gate, and the valve body can be replaced by disassembling the flanges at both ends of the valve body. This can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides a mud gate valve that is easy to replace, including a valve body and an extension pipe;

[0006] Flanges are connected to both ends of the valve body, and a valve cover is connected to the top of the valve body. A valve stem is provided inside the valve cover, and a turntable and a first gate are connected to both ends of the valve stem. The first gate is slidably installed inside the valve body.

[0007] The extension pipe is connected to one end of the valve body via a flange. A second gate is inserted into the extension pipe, and one end of the second gate is connected to a cylinder. A screw hole is provided on the extension pipe.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the second gate plate is provided with multiple breakage grooves.

[0010] Furthermore, the extended pipe is fixedly connected to the second gate by bolts.

[0011] Furthermore, a sealing surface is provided inside the extended pipe.

[0012] Furthermore, the central channel of the extension pipe is circular, and the end of the second gate near the extension pipe is arc-shaped to match the extension pipe.

[0013] Furthermore, the second gate is made of a rigid material.

[0014] The beneficial effects of this utility model are as follows: This utility model provides a mud gate valve that is easy to replace, and has the following advantages:

[0015] 1. This utility model uses a second gate to stop the mud flow, and then replaces the valve body by disassembling the flanges at both ends of the valve body, thus solving the problem that replacing existing mud gate valves requires shutting down the mud system.

[0016] 2. This utility model features a second gate that can be broken off. After the mud gate valve is replaced, the second gate is broken off and fixed by drilling, thus achieving a seal on the extension pipe. The inner edge shape of the second gate matches the shape of the extension pipe, thereby not affecting the flow of mud in the extension pipe.

[0023] The following is in conjunction with the appendix Figure 1-3The principles and features of this utility model are described below. The examples given are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of this utility model will become clearer from the following description and claims. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0024] It should be noted that when a component is described as "fixed to" another component, it can be directly on the other component or may have a component in between. When a component is described as "connected to" another component, it can be directly connected to the other component or may have a component in between. When a component is described as "set on" another component, it can be directly set on the other component or may have a component in between. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] like Figure 1-3 As shown, this utility model provides a mud gate valve that is easy to replace, including a valve body 1 and an extension pipe 7;

[0027] Flanges 2 are connected to both ends of the valve body 1, and valve cover 3 is connected to the top of the valve body 1. Valve stem 4 is provided inside the valve cover 3. Turntable 5 and first gate 6 are connected to both ends of the valve stem 4, and the first gate 6 is slidably installed inside the valve body 1.

[0028] The extension pipe 7 is connected to one end of the valve body 1 via flange 2. A second gate 8 is inserted inside the extension pipe 7. One end of the second gate 8 is connected to a cylinder 9. The cylinder 9 drives the second gate 8 to move in the extension pipe 7. A sealing surface 12 is provided inside the extension pipe 7 to ensure that the second gate 8 can perform sealing operations on the extension pipe 7.

[0029] After the second gate plate 8 seals the extension pipe 7, the mud is intercepted, allowing the valve body 1 to be replaced. After replacement, the cylinder 9 drives the second gate plate 8 to move in the extension pipe 7, thereby opening the channel in the extension pipe 7 and restoring the flow of mud. The second gate plate 8 is broken off by the break groove 11 on the second gate plate 8, leaving a part of the second gate plate 8 in the slot of the extension pipe 7. Holes are drilled on the second gate plate 8, which is made of rigid material, and bolts are used to connect the holes on the second gate plate 8 with the screw holes 10, thereby completing the connection between the broken second gate plate 8 and the extension pipe 7 and achieving the sealing of the extension pipe 7 by the second gate plate 8.

[0030] Furthermore, the central channel of the extension pipe 7 is circular, and the end of the second gate 8 near the extension pipe 7 is arc-shaped to match the extension pipe 7, so that the broken-off second gate 8 does not affect the flow of the extension pipe 7 after it is connected to the extension pipe 7.

[0031] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description.
