Description

Technical Field

[0001] This utility model relates to the field of pipeline control valve technology, and in particular to an easy-to-use oil mist purification pipeline control valve. Background Technology

[0002] In the field of industrial oil mist purification, traditional pipeline control valves have many inconveniences and defects. As industrial production continues to increase its requirements for oil mist purification efficiency and equipment stability, the shortcomings of existing control valves in terms of installation and maintenance have become increasingly prominent. Traditional control valves often have complex installation structures, requiring a lot of time for precise alignment and tightening during installation, and lack convenient disassembly design. Once the valve malfunctions and needs to be repaired or replaced, it often requires the use of professional tools and a long time to disassemble, which is quite troublesome. At the same time, the connection between the handwheel and the valve stem is usually relatively fixed, which is extremely inconvenient when the handwheel needs to be replaced or maintained, and it is impossible to quickly separate and reinstall it, which greatly limits the flexibility and efficiency of equipment maintenance. Therefore, we have introduced a new, easy-to-use oil mist purification pipeline control valve. Utility Model Content

[0003] The main objective of this invention is to provide an easy-to-use oil mist purification pipeline control valve that can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] An easy-to-use oil mist purification pipeline control valve includes a valve body. A connecting pipe is provided on both the left and right sides of the outer surface of the valve body. An installation mechanism is provided on the outer surface of each of the two connecting pipes. A lower end cover is fixedly installed on the upper part of the outer surface of the valve body via a fixing seat. An upper end cover is movably installed on the upper end of the lower end cover. A valve stem is provided at the middle of the upper end of the upper end cover. A fixing mechanism is movably engaged on the upper part of the outer surface of the valve stem via a positioning block. Three connecting rods are provided on the upper part of the outer surface of the fixing mechanism. A handwheel is provided on the upper part of the outer surface of the three connecting rods. A flange is provided at the end of each of the two connecting pipes away from the valve body. An external pipe is provided at the end of each of the two flanges away from the connecting pipes.

[0006] Preferably, the mounting mechanism includes a mounting base and an arc-shaped sleeve. The front and rear outer surfaces of the arc-shaped sleeve are provided with corresponding plates. The lower ends of the two corresponding plates are provided with corresponding blocks. The left and right inner sides of the two corresponding blocks are fixedly installed with first springs through inner grooves. The left and right inner sides of the two corresponding blocks are movably installed with movable blocks through inner grooves. The ends of the four movable blocks away from the corresponding first springs are provided with locking blocks. The front and rear ends of the mounting base are threaded with bolts through mounting ears. The front and rear upper ends of the mounting base are provided with corresponding seats. The left and right inner walls of the two corresponding seats are provided with locking holes.

[0007] Preferably, the arc-shaped sleeve is fixedly installed on the upper part of the outer surface of the connecting pipe, and the arc-shaped sleeve is movably engaged inside the two corresponding seats by corresponding blocks.

[0008] By adopting the above technical solution, the arc-shaped sleeve can be quickly and accurately installed in the corresponding seat through the corresponding block, thus achieving the purpose of rapid installation.

[0009] Preferably, the two corresponding blocks are movably engaged inside the two corresponding seats.

[0010] By adopting the above technical solution, the installation and disassembly of components are facilitated, making it easier to carry out maintenance and repairs in the future.

[0011] Preferably, the card block is movably engaged within the card hole by a first spring.

[0012] By adopting the above technical solution, the locking block can be stably held in the locking hole under the action of the spring, which plays the role of connecting and fixing the valve stem, ensuring the integrity of the structure, preventing the parts from accidentally falling off, and also facilitating subsequent quick disassembly and removal.

[0013] Preferably, the fixing mechanism includes a positioning sleeve, a fixing hole is provided on the front of the outer surface of the positioning sleeve, an extension sleeve is provided on the front of the outer surface of the positioning sleeve, a movable rod is movably installed at the front end of the extension sleeve, a pull block is provided at the front end of the movable rod, a driving block is fixedly installed at the rear end of the movable rod, an insert rod is fixedly installed at the middle of the rear end of the driving block, and a second spring is movably sleeved on the outer surface of the movable rod.

[0014] By adopting the above technical solution, the presence of the positioning sleeve can position the components it mates with, ensuring that the valve stem is installed in the accurate position.

[0015] Preferably, the fixing hole and the insertion rod are movably engaged inside the fixing hole, the outer surface of the driving block is movably fitted with the inner surface of the extension sleeve, and the second spring is fixedly connected to the front end of the driving block and the inner front wall of the extension sleeve respectively.

[0016] By adopting the above technical solution, the fixing mechanism can reliably fix the rod by relying on the spring force to push the insertion rod into the fixing hole under normal circumstances through the structure of movable rod, pull block and second spring.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The combination of the mounting base and the arc-shaped sleeve greatly facilitates the installation and disassembly of the entire valve body. During installation, the corresponding block and the corresponding seat cooperate, and the elastic force of the first spring on the locking block can easily achieve quick connection and fixation, shortening the installation time and improving work efficiency. When disassembly is required, only appropriate external force needs to be applied to overcome the spring force to smoothly separate the valve from the mounting base. This convenient disassembly method is conducive to the maintenance, repair and replacement of the equipment, reduces downtime caused by valve failure, and effectively improves the operational stability and maintainability of the entire oil mist purification pipeline system.

[0019] 2. The fixed mechanism facilitates the quick disassembly of the handwheel. Through the coordinated action of the pull block, movable rod, driving block, insertion rod, and second spring, the fixed connection between the handwheel and the valve stem can be quickly released or established. This facilitates the replacement of the handwheel when it is damaged or needs to be upgraded, improves the efficiency and flexibility of equipment maintenance, and ensures the long-term stable and reliable operation of the oil mist purification pipeline control valve.

[0028] Please see Figure 1-4 This utility model provides a technical solution:

[0029] An easy-to-use oil mist purification pipeline control valve includes a valve body 1. A connecting pipe 2 is provided on both the left and right sides of the outer surface of the valve body 1. An installation mechanism 3 is provided on the outer surface of each of the two connecting pipes 2. A lower end cover 4 is fixedly installed on the upper part of the outer surface of the valve body 1 via a fixing seat. An upper end cover 5 is movably installed on the upper end of the lower end cover 4. A valve stem 6 is provided at the middle of the upper end of the upper end cover 5. A fixing mechanism 7 is movably engaged on the upper part of the outer surface of the valve stem 6 via a positioning block. Three connecting rods 8 are provided on the upper part of the outer surface of the fixing mechanism 7. A handwheel 9 is provided on the upper part of the outer surface of the three connecting rods 8. A flange 10 is provided at the end of each of the two connecting pipes 2 away from the valve body 1. An external pipe 11 is provided at the end of each of the two flanges 10 away from the connecting pipe 2.

[0030] In this embodiment, the mounting mechanism 3 includes a mounting base 30 and an arc-shaped sleeve 31. Corresponding plates 32 are provided on both the front and rear sides of the outer surface of the arc-shaped sleeve 31. Corresponding blocks 33 are provided at the lower ends of the two corresponding plates 32. First springs 34 are fixedly installed on the inner left and right sides of the two corresponding blocks 33 via inner grooves. Movable blocks 35 are movably installed on the inner left and right sides of the two corresponding blocks 33 via inner grooves. A locking block 36 is provided at the end of each of the four movable blocks 35 away from the corresponding first spring 34. The mounting base 3... Both the front and rear ends of 0 are fitted with bolts 37 through mounting ears and threaded connections. The upper front and upper rear ends of the mounting base 30 are provided with corresponding seats 38. The inner left and inner right walls of the two corresponding seats 38 are provided with locking holes 39. The arc-shaped sleeve 31 is fixedly installed on the upper part of the outer surface of the connecting pipe 2. The arc-shaped sleeve 31 is movably locked inside the two corresponding seats 38 by corresponding blocks 33. The two corresponding blocks 33 are movably locked inside the two corresponding seats 38 respectively. The locking block 36 is movably locked inside the locking hole 39 by the first spring 34.

[0031] With the above solution: During installation, the two corresponding blocks 33 on the arc-shaped sleeve 31 are aligned with the two corresponding seats 38 on the mounting base 30 and moved downwards. As the corresponding blocks 33 enter the corresponding seats 38, the locking block 36 is squeezed by the inner wall of the corresponding seat 38, overcoming the elastic force of the first spring 34 and contracting into the inner groove of the corresponding block 33. When the corresponding blocks 33 are fully inserted into the corresponding seats 38, the locking block 36 pops out under the elastic force of the first spring 34 and locks into the locking hole 39 in the corresponding seat 38, realizing the quick installation and fixation of the arc-shaped sleeve 31 and the mounting base 30, thereby facilitating the quick fixation of the connecting pipe 2. During disassembly, external force needs to be applied to press the locking block 36 back into the inner groove of the corresponding blocks 33, so that the locking block 36 disengages from the locking hole 39, and then the arc-shaped sleeve 31 and the connecting pipe 2 as a whole can be taken out upwards.

[0032] In this embodiment, the fixing mechanism 7 includes a positioning sleeve 71. A fixing hole 72 is provided on the front of the outer surface of the positioning sleeve 71. An extension sleeve 73 is provided on the front of the outer surface of the positioning sleeve 71. A movable rod 74 is inserted and movably installed at the front end of the extension sleeve 73. A pull block 75 is provided at the front end of the movable rod 74. A driving block 76 is fixedly installed at the rear end of the movable rod 74. An insert rod 77 is fixedly installed at the middle of the rear end of the driving block 76. A second spring 78 is movably sleeved on the outer surface of the movable rod 74. The fixing hole 72 and the insert rod 77 are movably engaged inside the fixing hole 72. The outer surface of the driving block 76 is movably attached to the inner surface of the extension sleeve 73. The second spring 78 is fixedly connected to the front end of the driving block 76 and the inner front wall of the extension sleeve 73 respectively.

[0033] With the above solution: when fixation is required, the positioning sleeve 71 is placed on the corresponding component, and the insertion rod 77 is inserted into the fixing hole 72 under the elastic force of the second spring 78, so that the positioning sleeve 71 is stably fixed on the corresponding component, thereby realizing the fixed connection function of the whole device. When the fixation is to be released, the pull block 75 is pulled to drive the movable rod 74 forward, and the driving block 76 at the rear end of the movable rod 74 moves forward accordingly, compressing the second spring 78, and at the same time driving the insertion rod 77 to be pulled out from the fixing hole 72. At this time, the fixed connection between the positioning sleeve 71 and the corresponding component is released, and the valve stem 6 can be adjusted, disassembled or replaced.

[0034] It should be noted that this utility model is an easy-to-use oil mist purification pipeline control valve. During use, when installing the entire valve body 1, align the connecting pipe 2 with the arc-shaped sleeve 31 with the mounting base 30, so that the corresponding block 33 on the arc-shaped sleeve 31 corresponds vertically with the corresponding seat 38 on the mounting base 30. Then, insert the corresponding block 33 into the corresponding seat 38. During insertion, the elastic force of the internal first spring 34 contracts and returns to its original position, causing the corresponding locking block 36 to engage in the corresponding locking hole 39, thereby achieving the installation and fixation of the valve body 1. To disassemble, external force must be applied to make the locking block 36 overcome the elastic force of the first spring 34 and disengage from the locking hole 39, and then the corresponding block 33 can be pulled out from the corresponding seat 38. When the handwheel 9 is turned, the handwheel 9 drives the fixing mechanism through the three connecting rods 8. 7. Rotation: Due to the movable engagement between the positioning block and the valve stem 6, the fixing mechanism 7 drives the valve stem 6 to rotate. The rotation of the valve stem 6 controls the valve core inside the valve body 1. When the handwheel 9 needs to be disassembled and replaced, the pull block 75 is pulled, which drives the movable rod 74 forward. The driving block 76 at the rear end of the movable rod 74 moves forward accordingly, compressing the second spring 78. The insertion rod 77 is pulled out from the fixing hole 72. At this time, the fixed connection between the positioning sleeve 71 and the valve stem 6 is released, allowing for quick disassembly. During installation, the positioning sleeve 71 is placed on the appropriate position on the outer surface of the valve stem 6. The insertion rod 77 is inserted into the fixing hole 72 under the elastic force of the second spring 78. At the same time, the outer surface of the driving block 76 is tightly fitted with the inner surface of the extension sleeve 73, ensuring that the positioning sleeve 71 is stably fixed on the valve stem 6.
