Description

Technical Field

[0001] This utility model relates to the field of ball valve technology, and in particular to a regulating ball valve for natural gas. Background Technology

[0002] A ball valve is a type of valve widely used in pipeline systems, primarily for cutting off, distributing, or changing the flow direction of media.

[0003] In the process of natural gas transportation, distribution and use, it is necessary to accurately regulate parameters such as natural gas flow and pressure. As an important control device, regulating ball valves are widely used in natural gas systems. In the existing technology, natural gas contains certain impurities and particles. During long-term use, these impurities can easily cause wear on the valve core and valve seat of the ball valve, affecting the valve's regulation accuracy and service life. In severe cases, it can even cause perforation of the ball valve shell, resulting in natural gas leakage and insufficient safety. Therefore, it is necessary to redesign a natural gas-specific regulating ball valve to address the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a special regulating ball valve for natural gas.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A natural gas-specific regulating ball valve includes a valve housing. The inner wall of the valve housing has multiple mounting grooves. A prismatic rod is fixedly installed inside each mounting groove. A sliding sleeve is slidably installed on the outer wall of each prismatic rod. The outer wall of each sliding sleeve is connected to the inner wall of the corresponding mounting groove via an elastic mechanism. Each sliding sleeve on the same side has a compression plate fixedly connected to its outer wall via a connecting mechanism. Compression pads, made of vulcanized rubber, are fixedly installed on the inner walls of both compression plates. A slot is provided inside the valve housing. A pull-out opening communicating with the slot is provided on the outer wall of the valve housing. A connecting channel that mates with the pull-out opening is fixedly installed on the outer wall of the valve housing. A connecting plate is slidably installed inside the slot. A filter funnel is fixedly installed on the outer wall of the connecting plate. A cover plate is fixedly installed at the end of the connecting plate. A bolt is rotatably installed through the outer wall of the valve housing via a support mechanism. A lower pressure plate is rotatably connected to the end of the bolt via a connecting mechanism.

[0007] Preferably, the elastic mechanism includes a compression spring installed on the outer wall of the prism rod, with both ends of the compression spring elastically connected to the inner wall of the mounting groove and the outer wall of the sliding sleeve, respectively.

[0008] Preferably, the connecting mechanism includes a connecting rod fixedly installed on the outer wall of the sliding sleeve, and the end of the connecting rod is fixedly connected to the outer wall of the extrusion plate.

[0009] Preferably, the support mechanism includes a support plate fixedly installed on the outer wall of the valve housing, and the bolt passes through the support plate by threaded rotation.

[0010] Preferably, the connecting mechanism includes a connecting block fixedly installed at the end of the bolt, and the end of the connecting block is rotatably connected to the upper surface of the lower pressure plate.

[0011] Preferably, a sealing gasket for connecting channels is fixedly installed on the bottom wall of the cover plate, and the sealing gasket is made of silicone.

[0012] The beneficial effects of this utility model are:

[0013] 1. By setting up components such as connecting channels, connecting plates, and filter buckets, and by utilizing the ingenious cooperation between the connecting channels and the pull-out opening, the connecting plate can be easily inserted into the slot, enabling convenient installation of the filter bucket inside the valve housing. The cover plate can tightly cover the upper surface of the connecting channel, while the sealing gasket is compressed to further enhance the sealing effect. During the natural gas transportation process, the filter bucket plays a key role in efficiently intercepting impurities and particles in the natural gas.

[0014] 2. By setting up components such as compression springs, sliding sleeves, and compression pads, the elastic force of multiple compression springs causes the sliding sleeve to slide smoothly along the prismatic rod, thereby driving the connecting rod, compression plate, and compression pad to move precisely, so that the compression pad fits tightly against the outer wall of the valve core. This tight-fitting sealing structure greatly enhances the sealing performance of the ball valve in the closed state. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5 A natural gas-specific regulating ball valve includes a valve housing 1. The inner wall of the valve housing 1 has multiple mounting grooves. A prismatic rod 2 is fixedly installed inside each mounting groove. A sliding sleeve 3 is slidably installed on the outer wall of each prismatic rod 2. The unique shape of the prismatic rod 2 serves as a guide for the sliding sleeve 3 and also enhances the structural mechanical properties. The sliding sleeve 3 can slide flexibly along the axial direction of the prismatic rod 2. The outer wall of each sliding sleeve 3 is connected to the inner wall of the corresponding mounting groove through an elastic mechanism. The elastic mechanism includes a compression spring 4 installed on the outer wall of the prismatic rod 2. The two ends of the compression spring 4 are elastically connected to the inner wall of the mounting groove and the outer wall of the sliding sleeve 3, respectively.

[0023] Each sliding sleeve 3 on the same side has an extrusion plate 6 fixedly connected to its outer wall via a connecting mechanism. The connecting mechanism includes a connecting rod 5 fixedly installed on the outer wall of the sliding sleeve 3. The end of the connecting rod 5 is fixedly connected to the outer wall of the extrusion plate 6. Extrusion pads 7 are fixedly installed on the inner walls of both extrusion plates 6. The extrusion pads 7 are made of vulcanized rubber. Vulcanized rubber refers to rubber that has been vulcanized and has properties such as non-stickiness and difficulty in breaking. It also has high elasticity, heat resistance, tensile strength, and insolubility in organic solvents. A slot is provided inside the valve housing 1. A pull-out opening communicating with the slot is provided on the outer wall of the valve housing 1. A connecting channel 8 that mates with the pull-out opening is fixedly installed on the outer wall of the valve housing 1. A connecting plate 9 is slidably installed inside the slot.

[0024] A filter hopper 10 is fixedly installed on the outer wall of the connecting plate 9. A cover plate 11 is fixedly installed at the end of the connecting plate 9. A sealing gasket 12 that matches the connecting channel 8 is fixedly installed on the bottom wall of the cover plate 11. The sealing gasket 12 is made of silicone. A bolt 14 is rotatably installed through the outer wall of the valve housing 1 via a support mechanism. The support mechanism includes a support plate 13 fixedly installed on the outer wall of the valve housing 1. The bolt 14 rotatably passes through the support plate 13 via a thread. A lower pressure plate 16 is rotatably connected to the end of the bolt 14 via a connecting mechanism. The connecting mechanism includes a connecting block 15 fixedly installed at the end of the bolt 14. The end of the connecting block 15 is rotatably connected to the upper surface of the lower pressure plate 16.

[0025] When this utility model is in use, the elastic compression of multiple compression springs 4 allows the sliding sleeve 3 to slide on the outer wall of the prismatic rod 2. At this time, multiple sliding sleeves 3 on the same side can move the compression plate 6 on the same side through the cooperation of the connecting rod 5. This allows the two compression plates 6 to respectively drive the compression pad 7 on their inner walls to fit against the outer wall of the valve core. Under the elastic compression of multiple compression springs 4, the compression pad 7 can fit tightly against the outer wall of the valve core, thereby increasing the sealing effect of the ball valve in the closed state, preventing natural gas leakage, and avoiding energy waste and safety hazards.

[0026] Before installing the ball valve, the connecting plate 9 can be inserted into the slot through the cooperation of the connecting channel 8 and the pull-out opening, thereby enabling convenient installation of the filter 10 inside the valve housing 1. Then, the cover plate 11 can be used to cover the upper surface of the connecting channel 8. Next, the lower pressure plate 16 can be rotated through the cooperation of the connecting block 15, causing the lower pressure plate 16 to rotate to the upper surface of the cover plate 11 (e.g., ...). Figure 1 As shown), finally, the bolt 14 can be tightened to cause the lower pressure plate 16 to descend through the connecting block 15 and press down on the cover plate 11. At this time, the cover plate 11 is under force and can squeeze the sealing gasket 12, increasing the sealing between the bottom wall of the cover plate 11 and the upper end face of the connecting channel 8. When natural gas is transported through the ball valve, the filter hopper 10 can intercept and filter impurities and particles inside the natural gas, thereby avoiding wear on the valve core and valve seat of the ball valve, thus ensuring the adjustment accuracy and service life of the valve.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
