Background
The cartridge valve is also called a cartridge cone valve or a logic valve and is composed of a cartridge assembly, a pilot control valve, a control cover plate and an integrated valve block, wherein the cartridge assembly (shown in figure 2) is composed of a valve core 5, a valve sleeve, a spring and a sealing element. The cartridge valve is a novel hydraulic control valve with simple structure, high standardization and universalization degree, large oil passing capacity, small hydraulic resistance and good sealing performance and dynamic characteristics. The method is widely applied to high-pressure large-flow systems such as hydraulic presses, plastic forming machines, die casting machines and the like at present.
Currently, cartridge valves are installed as follows: processing a mounting hole on the integrated valve block according to the outer diameter of the plug-in component, and mounting the plug-in component in the mounting hole; and after the cartridge assembly is inserted into the integrated valve block, the control cover plate is installed, and finally the pilot control valve is installed, so that the installation of the cartridge valve is completed. In order to ensure that the internal leakage does not occur between the plug-in component and the mounting hole, when the plug-in component is mounted, a sealing ring is arranged on the outer circumferential surface of the plug-in component; meanwhile, the outer circumferential surface of the plug-in component is tightly matched with the mounting hole; therefore, after the cartridge assembly is installed on the integrated valve block, the cartridge assembly is difficult to disassemble.
The traditional dismounting tool for the cartridge valve is formed by bending a steel wire, two ends of the steel wire extend outwards to form hooks (as shown in figure 3), when dismounting is carried out, the steel wire is firstly gripped to place the hooks of the steel wire into the valve core bayonets 5a, then an iron rod is arranged on the inner side of the bending part of the steel wire, and finally upward acting force is applied to the iron rod. This dismantlement mode is dismantled the degree of difficulty on the one hand and is big, the dismantlement time is than longer, and the flexion of on the other hand steel wire is because frequent deformation, often receives strong effort in addition, and the easy fracture takes place for the flexion, and this extracting tool still need dispose an iron bar in addition, has still increased the complexity of dismantling when increasing the cost.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a simple structure, convenient to carry, dismantle convenient quick, the not fragile valve cartridge extracting tool.
In order to realize the above-mentioned purpose, the utility model provides a plug-in valve extracting tool, including connecting rod, sleeve, pull rod, the sleeve cover is established in the connecting rod, the pull rod sets firmly at the connecting rod top perpendicularly, and the length of pull rod is greater than telescopic external diameter, the bottom of connecting rod is equipped with the overhead kick, the size of overhead kick and the case bayonet socket size phase-match of plug-in valve, the overhead kick is greater than the distance of case bayonet socket to case top to the distance of sleeve bottom.
In the scheme, the method comprises the following steps: the width sum of the barb and the connecting rod is greater than the internal diameter of the sleeve, so that the sleeve cannot penetrate out of the connecting rod, the use convenience of the plug-in valve dismounting tool is improved, the sleeve and the connecting rod are integrated, and an operator can carry the plug-in valve dismounting tool with one hand.
In the scheme, the method comprises the following steps: the outer diameter of the sleeve is set to be suitable for being held by a hand, so that an operator can hold the sleeve to move upwards to impact the pull rod conveniently, and an upward acting force is applied to the pull rod.
In the scheme, the method comprises the following steps: the middle part of the pull rod is fixed on the connecting rod, and the sleeve can apply acting force to two ends of the pull rod simultaneously, so that the balance and stability of the dismounting tool during dismounting can be guaranteed.
In the scheme, the method comprises the following steps: the connecting rod, the pull rod and the sleeve are all made of steel materials, wherein the connecting rod and the pull rod are made of steel bars, so that the material is saved, the maintenance and replacement cost of a disassembling tool is reduced, and the steel materials are high in strength, small in deformation and small in abrasion and are difficult to damage in the disassembling process.
The utility model has the advantages that: compared with the traditional dismounting tool for the cartridge valve, the utility model has convenient and quick dismounting, and the dismounting of the traditional dismounting tool for the cartridge valve needs one hour, and the dismounting of the utility model needs only ten minutes; furthermore, the utility model discloses an utilize the sleeve upwards to strike the pull rod and give an ascending effort of pull rod to let the cartridge subassembly break away from the integrated valve piece gradually, the power of sleeve upwards striking is very big, compares traditional extracting tool the utility model discloses more laborsaving.
