Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a valve that can be disassembled under pressure. Background Art

[0002] The concept of a valve that can be disassembled under pressure refers to a design that allows the valve to be disassembled and replaced without closing the valve control pipeline. The copper sleeve of this valve usually adopts a modular design to facilitate disassembly and replacement, and at the same time has a certain load-bearing capacity and wear resistance to increase service life.

[0003] When removing or installing the copper sleeve of the existing valve that can be disassembled under pressure, it is usually necessary to use a valve stem fixing mechanism to fix the valve stem to prevent the movement of the valve stem from affecting the removal and installation of the copper sleeve, so as to achieve the purpose of disassembly under pressure. However, the use of the valve stem fixing mechanism increases the complexity of the operation and may cause the valve stem to be loosely fixed, thereby affecting the safety and accuracy of the operation.

The valve that can be disassembled under pressure includes: a copper sleeve 1, a valve stem 10 is arranged inside the copper sleeve 1, four spring grooves 2 are opened on the valve stem 10, springs 3 are fixedly connected inside the four spring grooves 2, the springs 3 are compression springs, and the other end of the spring 3 is fixedly connected to a clamping rod 5, a clamping rod groove 4 is opened on the surface of the valve stem 10, a clamping shaft 6 is rotatably connected inside the clamping rod groove 4, and the clamping shaft 6 is fixedly connected to the clamping rod 5, a threaded groove 7 is opened on the outer surface of the copper sleeve 1, and a mounting block 8 is threadedly connected to the outer surface of the copper sleeve 1, and four clamping grooves 9 are opened on the inner wall of the mounting block 8. The automatic locking and unlocking function of the valve can ensure the safe disassembly and installation of the copper sleeve, reduce equipment failures caused by human operating errors, and enhance the reliability of the equipment.

[0021] A graphite block 11 is arranged inside the copper sleeve 1, a connecting plate 12 is fixedly connected to the bottom of the mounting block 8, a valve 13 is fixedly connected to the bottom of the valve stem 10, the graphite block 11 can ensure the lubricity inside the copper sleeve 1, and the rotation of the valve stem 10 controls the opening and closing of the valve 13.

[0022] The upper surface of the valve stem 10 is fixedly connected with a clamping block 14, and the top of the valve stem 10 is clamped with a valve button 15, which is clamped on the clamping block 14. It is convenient for the operator to control the opening and closing of the valve 13.

[0023] Four shift blocks 17 are slidably connected to the top of the connecting plate 12, and a shift slot 16 is provided at the bottom of the mounting block 8. The shift block 17 can be extended and retracted, and the shift block 17 is stuck in the shift slot 16 to facilitate the positioning of the card rod 5 so that it can be accurately inserted into the card slot 9.

[0024] A disassembly mechanism 18 is provided on the top of the mounting block 8, and two guide sleeves 19 are fixedly connected to the disassembly mechanism 18. An adjusting rod 20 is slidably connected inside the guide sleeve 19. An arcuate threaded block 21 is fixedly connected to the other end of the adjusting rod 20. A rotating adjusting rod 22 is threadedly connected inside the arcuate threaded block 21. The rotating adjusting rod 22 is rotated to move the adjusting rod 20 to the right, and the thread groove on the inner wall of the arcuate threaded block 21 is in close contact with the thread groove 7 on the copper sleeve 1.

[0026] The working principle of the valve that can be disassembled under pressure provided by the utility model is as follows: after the copper sleeve 1 is taken out, the copper sleeve 1 moves upward, leaving a chamber. When the copper sleeve 1 has not completely left the chamber, the spring 3 in the spring groove 2 pushes out the clamping rod 5, and the end of the clamping rod 5 connected to the clamping shaft 6 is fixed, and the lower end is rotated to the inside of the clamping groove 9, so that the valve stem 10 will not rotate, so that the device can complete the replacement of the copper sleeve 1 under pressure, and there is no need to use a valve stem fixing mechanism to fix the valve stem 10. When the copper sleeve 1 is installed, there is no need to use a valve stem fixing mechanism. When the copper sleeve 1 moves downward, the clamping rod 5 will be pressed back into the clamping groove 9 due to the downward angle of the clamping rod 5. The whole process only requires the replacement operation of the copper sleeve 1, and the valve stem 10 will be self-locking and automatically cancel the fixation.

[0027] Compared with the related art, the valve that can be disassembled under pressure provided by the utility model has the following beneficial effects:

[0028] By providing a valve stem 10 that can be automatically fixed after the copper sleeve 1 is removed, there is no need to use a valve stem fixing mechanism, which reduces the operating steps and eliminates the need to spend time and energy on finding and operating the valve stem fixing mechanism, thereby improving maintenance efficiency. In addition, the copper sleeve 1 can not only complete the disassembly operation under pressure, avoiding accidents caused by the movement of the valve stem 10 and improving the safety of operation, but also saves the design and manufacturing costs of the valve stem fixing mechanism, thereby reducing the cost of the entire equipment.
