Abstract
The utility model discloses a special tool for dismounting and mounting an emergency distributing valve piston. The special tool comprises at least four double-thread screws and a base connected with the screws. Screw holes are evenly distributed on the base, the double-thread screws penetrate through the screw holes, the number of the screw holes is equal to the number of the double-thread screw rods, and an adjusting nut and a locking nut which are respectively arranged on two sides of the base are arranged on each double-thread screw. The special tool is simple in structure and convenient to operate, can smoothly dismount and mount the emergency distributing valve piston, is high in work efficiency and can provide the convenient and effective solution scheme for dismounting and mounting the emergency distributing valve piston.
Description
Technical field
The utility model relates to a kind of instrument, specifically is a kind of emergency distributing valve piston tool specially for attaching and detaching that is used for the hydraulic generator unit.
Background technology
At present in the hydrogenerator maintenance process, the dismounting of emergency distributing valve piston mostly is to adopt the hammering method to carry out, adopt the method still can for the less emergency distributing valve of piston diameter, reach the emergency distributing valve of 200mm for piston diameter, carry out relatively difficulty of dismounting if adopt the hammering method, as easy as rolling off a logly cause device damage, and operating efficiency is not high yet.
The utility model content
Technical problem to be solved in the utility model provides a kind of emergency distributing valve piston tool specially for attaching and detaching, makes it like a cork the emergency distributing valve piston be carried out dismounting, increases work efficiency.
The utility model solves the problems of the technologies described above with following technical scheme:
The utility model emergency distributing valve piston tool specially for attaching and detaching, it comprises the base of at least four double threaded screws and connecting screw rod, be evenly equipped with screw identical with double threaded screw quantity and that supply double threaded screw to pass on the base, be furnished with adjustment nut and the locking nut that places the base both sides respectively on the every double threaded screw.
The utility model emergency distributing valve piston tool specially for attaching and detaching, the screw on the described base and the quantity of double threaded screw are four.
Base described in the utility model is that a, thickness the same with emergency distributing valve both sides end cap size is the Q235 steel plate of 20mm, has additional reinforcement on the base.
The utility model emergency distributing valve piston tool specially for attaching and detaching has following advantage:
1, instrument dismounting arbitrarily, easy to carry, occupy little space, easily keeping.
2, simple in structure, easy to operate, can be like a cork with the dismounting of emergency distributing valve piston.
3, can carry out work at narrow working space, and can increase work efficiency, for the dismounting of emergency distributing valve piston provides convenient, an effective solution like a cork with the dismounting of emergency distributing valve piston.
Description of drawings
Fig. 1 is the structural representation of the utility model emergency distributing valve piston tool specially for attaching and detaching.
Fig. 2 is that schematic diagram is looked on the left side of the base 2 among Fig. 1.
Fig. 3 is the structural representation of emergency distributing valve.
Among the figure: 1-adjusts nut, 2-base, 3-double threaded screw, 4-locking nut, 5-reinforcement, 6-screw, 7-servomotor is opened the chamber, and 8-servomotor cuts out the chamber, and 9-main control valve cuts out the chamber, 10-main control valve is opened chamber, 11-left side end cap, 12-right side end cap, 13-piston.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
The structure of hydrogenerator emergency distributing valve as shown in Figure 3, it comprises that piston 13, servomotor open chamber 7, servomotor and close that chamber 9 is closed in chamber 8, distributing valve, main control valve is opened chamber 10, the two ends of piston 13 are respectively equipped with left side end cap 11 and right side end cap 12.Traditional assembly and disassembly methods is: after the both sides end cap of piston 13 is taken off, directly impact piston with hammer and carry out dismounting, be easy to cause device damage, and operating efficiency is not high.
The utility model emergency distributing valve piston tool specially for attaching and detaching as depicted in figs. 1 and 2, it comprises the base 2 of four double threaded screws 3 and connecting screw rod 3, symmetry is evenly equipped with for four screws 6 that double threaded screw 3 passes on the base 2, is furnished with adjustment nut 1 and the locking nut 4 that places base 2 both sides respectively on the every double threaded screw.
Described base 2 is that a, thickness the same with emergency distributing valve both sides end cap size is the Q235 steel plate of 20mm, sets up reinforcement 5 on the base, and the double threaded screw quantity of passing the screw 6 on the base 2 is corresponding with the bolt hole on the end cap of emergency distributing valve body both sides.
During use, is emergency distributing valve both sides end cap that left end cap 11 and right end cap 12 unload (two of Fig. 3), M30 * 70 terminal screws of four double threaded screws 3 of specific purpose tool are screwed into emergency distributing valve body end bolt hole (the right-hand member place of Fig. 3), with locking nut 4 lockings, then base 2 is put the other end of four double threaded screws 3, adjust the adjustment nut 1 of base rear end, make between base 2 and the piston 13 apart from placing screw jack, when carrying out dismounting, the pedestal of screw jack is placed on the base 2, the expansion link of screw jack is withstood piston 13, just can finish the disassemble and assemble work of piston by the operation jack, high efficiency, and piston is difficult for being damaged.
The utility model utilizes base as the stressed fixed support of screw jack, and screw jack ejects piston or the piston jacking is installed by the reaction force of base.
Double threaded screw quantity and the screw quantity on the corresponding base that the utility model adopts also can be provided with a plurality of as required.
