Embodiment Construction

[0011] figure 1 The shown disassembly tooling for a high-pressure safety valve includes a valve 1, a pressure plate 2, a lock nut 3, a valve stem 4, a spring 5, a yoke rod 6, a valve core 7, a limiting boss 8, a hydraulic pump 9, and a hydraulic cylinder 10 , Sleeve coupling 11, central hole 12, shoulder structure 13.

[0012] figure 1 The high-pressure safety valve dismounting tool is set directly above the valve pressing device, and the pressing device includes a pressing plate 2, a lock nut 3, a valve stem 4, a spring 5 and two symmetrical and vertically arranged yoke rods 6, The spring 5 is mainly used to provide a certain pressure. One end of the spring 5 is pressed against the valve core 7, and the other end is pressed against the bottom surface of the pressure plate 2 through the limit boss 8. The two ends of the pressure plate 2 pass through the symmetrical and vertically arranged yoke rods 6, And put the lock nut 3 on the yoke rod 6, so as to provide a certain pre-c...

Abstract

The invention discloses a high-pressure safety valve disassembling tool. A pressing device is arranged on a valve and comprises a pressing plate, locking nuts, a valve stem, a spring and two symmetrically and vertically arranged yoke bars, two ends of the pressing plate penetrate through the yoke bars, the locking nuts are sleeved on the yoke bars and abutted to the top of the pressing plate, the lower end of the valve stem is abutted to a valve spool, and the spring is arranged on the valve stem between the pressing plate and the valve spool. The high-pressure safety valve disassembling tool is characterized in that the high-pressure safety valve disassembling tool is vertically mounted right above the valve pressing device and comprises a hydraulic pump, a hydraulic cylinder and a sleeve coupling, the hydraulic cylinder is vertically placed on the pressing plate, the hydraulic pump is connected with an oil inlet of the hydraulic cylinder, the sleeve coupling penetrates through a center hole of a core of the hydraulic cylinder, the bottom of the sleeve coupling is connected with the valve stem in a threaded manner, and the top of the sleeve coupling is of a shoulder structure. By arranging an oil cylinder right above the pressing device, a downward force is provided, so that the locking nuts do not bear acting force from the spring and can be easily unscrewed.

Description

technical field [0001] The invention relates to a high-pressure safety valve disassembly tool, in particular to a high-pressure safety valve disassembly tool with convenient disassembly and high efficiency. Background technique [0002] The high-pressure safety valve is mainly used in occasions where the pipeline pressure is relatively high. The spring in the pressing device directly above the valve provides a certain pressure to resist the valve core. One end of the spring is against the valve core, and the other end is against the valve core. On the limit boss at the end of the valve stem, and the limit boss is against the pressure plate above it, and the two ends of the pressure plate are sleeved on the vertical and symmetrical yoke rods on both sides. The tight nut compresses the pressure plate, thereby using two lock nuts to respectively provide a downward force to counteract the upward force of the spring against the pressure plate. When the valve breaks down and need...
