Technical Field

[0001] The utility model relates to the technical field of split valve sleeves, in particular to a quick-disassembly device for split valve sleeves. Background Technique

[0002] As a kind of hydraulic valve with a special installation and connection form, cartridge valves have achieved great development since the 1970s. With the process of China's modernization, especially the increasingly wide application of mobile hydraulic machinery, the application of cartridge valves in China has also advanced by leaps and bounds.

[0003] When the existing valve sleeve is disassembled, it is usually disassembled by knocking the valve sleeve inside. However, removing the valve sleeve by knocking consumes a lot of manpower and time, which is not conducive to quickly disassembling the valve sleeve and reduces the use effect of the device.

[0004] Therefore, we propose a quick-disassembly device for split valve sleeves to solve the problems raised above. Content of the Utility Model

[0005] The purpose of the utility model is to provide a quick-disassembly device for split valve sleeves to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A quick-disassembly device for split valve sleeves includes a jacking tooling block and a plug that is slidably inserted into the inner cavity of the jacking tooling block. A fixing component is installed at the top of the plug, and a plug gauge is installed at the top of the inner cavity of the plug. A valve sleeve body is arranged near the middle of the inner cavity of the jacking tooling block, and the lower end of the plug gauge extends into the inner cavity of the valve sleeve body. The outer side of the valve sleeve body is connected to the inner cavity of the jacking tooling block through a plurality of O-rings. An oil passage hole is arranged at the lower part of the inner cavity of the jacking tooling block.

[0007] Preferably, the fixing component includes a housing fittingly installed at the top of the plug and an extrusion block slidably installed at the middle of the bottom wall of the inner cavity of the housing. A threaded rod is movably installed at the rear side of the extrusion block, and the rear end of the threaded rod threadedly penetrates and extends to the outside of the housing. Trapezoidal blocks are respectively fittingly installed on both sides of the extrusion block, and sliding rods are respectively fixedly installed on the outer sides of the trapezoidal blocks. The outer ends of the sliding rods respectively slide through and extend to the outside of the housing, and clamping plates are respectively fixedly installed at the outer ends of the sliding rods.

[0008] Preferably, a knob is fixedly installed at the rear end of the threaded rod.

[0009] Preferably, springs are respectively sleeved on the output shafts of the sliding rods, and the two ends of the springs are respectively fixedly installed on the trapezoidal blocks and the inner wall of the housing cavity.

[0010] Preferably, side plates are fixedly installed on both sides of the bottom of the outer shell, bolts are movably inserted through the side plates respectively, mounting plates are arranged on the inner sides of the side plates respectively, and the inner sides of the mounting plates are fixedly installed on the plugs respectively. The output ends of the bolts are inserted into the outer wall of one side of the mounting plates through threads respectively.

[0011] Preferably, a plurality of sealing holes for matching with O-rings are equidistantly arranged on the outer side of the valve sleeve body from top to bottom.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] Through the setting of the plug, the movement range of the plug gauge can be limited, so that the plug gauge can effectively seal the inner hole of the valve sleeve body, and there is a certain movement gap between the plug and the valve sleeve body, which is convenient for the pressure of the hydraulic oil to act entirely on the bottom of the valve sleeve body and the bottom of the plug gauge.

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Embodiment 1: Please refer to Figures 1-4 and Figures 6-8 , a quick-disassembly device for a split valve sleeve, including a jack tooling block 1 and a plug 2 slidably inserted at the bottom into the inner cavity of the jack tooling block 1. A fixing component 3 is installed at the top of the plug 2, and a plug gauge 4 is installed at the top of the inner cavity of the plug 2. A valve sleeve body 5 is provided near the middle of the inner cavity of the jack tooling block 1, and the lower end of the plug gauge 4 extends into the inner cavity of the valve sleeve body 5. The outer side of the valve sleeve body 5 and the inner cavity of the jack tooling block 1 are connected by a plurality of O-rings 6. An oil passage hole 7 is provided at the lower part of the inner cavity of the jack tooling block 1. The setting of the plug 2 can limit the movement range of the plug gauge 4, facilitating the disassembly of the valve sleeve body 5, and the setting of the fixing component 3 can fix the plug 2, improving the effect of restricting the plug gauge 4.

[0025] A plurality of sealing holes for matching with the O-ring 6 are equidistantly arranged from top to bottom on the outer side of the valve sleeve body 5, improving the use effect.

[0026] In this embodiment: During use, the setting of the plug 2 can limit the movement range of the plug gauge 4, enabling the plug gauge 4 to effectively seal the inner hole of the valve sleeve body 5. There is a certain movement gap between the plug 2 and the valve sleeve body 5, so that the pressure of the hydraulic oil acts entirely on the bottom of the valve sleeve body 5 and the bottom of the plug gauge 4. There is also a certain gap between the plug gauge 4 and the valve sleeve body 5. Pressure is applied to the bottom of the valve sleeve body 5 and the bottom of the plug gauge 4 through the oil passage hole 7 of the hydraulic oil jack tooling block 1. Since the plug 2 restricts the movement range of the plug gauge 4, by adjusting the pressure of the oil passage hole 7, the valve sleeve body 5 is pushed towards the plug 2 using the hydraulic oil. When the O-ring 6 leaves its corresponding sealing position, the valve sleeve body 5 can be taken out, improving the disassembly effect.

[0027] Embodiment 2: This embodiment is an improvement made on the basis of Embodiment 1. Specifically, please refer to Figures 1-7 , the fixing component 3 includes a housing 31 fitted and installed on the top of the plug 2 and an extrusion block 32 slidably installed in the middle of the inner bottom wall of the housing 31. A threaded rod 33 is movably installed at the rear side of the extrusion block 32, and the rear end of the threaded rod 33 threadedly penetrates and extends to the outside of the housing 31. Trapezoidal blocks 34 are respectively fitted and installed on both sides of the extrusion block 32. Slide rods 35 are respectively fixedly installed on the outer sides of the trapezoidal blocks 34. The outer ends of the slide rods 35 respectively slide through and extend to the outside of the housing 31, and clamping plates 36 are respectively fixedly installed at the outer ends of the slide rods 35. By driving the relative movement of the clamping plates 36, the plug 2 can be fixed on the jack tooling block 1.

[0028] A knob 331 is fixedly installed at the rear end of the threaded rod 33, which is convenient for driving the threaded rod 33 to rotate.

[0029] Spring 351 is respectively sleeved on the output shafts of the slide rods 35, and both ends of the spring 351 are respectively fixedly installed on the trapezoidal block 34 and the inner wall of the housing 31. The arrangement of the spring 351 facilitates the movement and restoration of the slide rod 35.

[0030] Side plates 311 are respectively fixedly installed at both sides of the bottom of the housing 31, and bolts 312 are respectively movably penetrated and installed on the side plates 311. Installation plates 313 are respectively arranged on the inner sides of the side plates 311, and the inner sides of the installation plates 313 are respectively fixedly installed on the plug 2. The output ends of the bolts 312 are respectively threadedly inserted on the outer wall of one side of the installation plate 313, which can play a role in the installation and disassembly of the housing 31.

[0031] In this embodiment: When the plug 2 is slidably inserted into the jack tooling block 1, the knob 331 can be rotated. When the knob 331 rotates, it will drive the threaded rod 33 to rotate. When the threaded rod 33 rotates, it will drive the extrusion block 32 to move backward. When the extrusion block 32 moves backward, the extrusion on the trapezoidal block 34 will gradually disappear. At this time, the trapezoidal block 34 will move and restore relative to each other under the action of the resilience of the spring 351, so as to drive the clamping plate 36 to move relatively through the slide rod 35, and the plug 2 can be clamped and fixed on the jack tooling block 1, improving the effect of restricting the movement range of the plug gauge 4 by the plug 2.

[0032] Working principle: When in use, the setting of the plug 2 can limit the movement range of the plug gauge 4, enabling the plug gauge 4 to effectively seal the inner hole of the valve sleeve body 5. There is a certain clearance between the plug 2 and the valve sleeve body 5, so that the pressure of the hydraulic oil acts entirely on the bottom of the valve sleeve body 5 and the bottom of the plug gauge 4. There is also a certain clearance between the plug gauge 4 and the valve sleeve body 5. Pressure is applied to the bottom of the valve sleeve body 5 and the bottom of the plug gauge 4 through the oil passage hole 7 of the hydraulic oil jacking tooling block 1. Since the plug 2 limits the movement range of the plug gauge 4, by adjusting the pressure of the oil passage hole 7, the valve sleeve body 5 is pushed towards the plug 2 by the hydraulic oil. When the O-ring 6 leaves its corresponding sealing position, the valve sleeve body 5 can be removed, improving the disassembly effect. When the plug 2 is slidably inserted into the jacking tooling block 1, the knob 331 can be rotated. When the knob 331 rotates, it drives the threaded rod 33 to rotate. When the threaded rod 33 rotates, it drives the extrusion block 32 to move backward. When the extrusion block 32 moves backward, it gradually loses the extrusion on the trapezoidal block 34. At this time, the trapezoidal block 34 will move and recover relatively under the action of the resilience of the spring 351, and then drive the clamping plate 36 to move relatively through the sliding rod 35, so as to clamp and fix the plug 2 on the jacking tooling block 1, improving the effect of the plug 2 limiting the movement range of the plug gauge 4.

[0033] The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
