Safety valve testing table is a kind of equipment of safety valve Performance Detection, and it is applicable to casing rigidity and the sealing property take-off/regulation experiment of all kinds of flange form safety valve.But current existing safety valve testing table often, in the time of test, lacks safeguard procedures, once test failure easily causes windfall loss.
Utility model content
The utility model, for above-mentioned the deficiencies in the prior art, provides the double that a kind of safeguard procedures are complete, security is higher safety valve testing table.
The utility model is achieved by the following technical solution:
A kind of double safety valve testing table, comprises left-hand worktable and dextrad worktable, and is arranged on the switch board between left-hand worktable and dextrad worktable, the below of described switch board is provided with gas drive supercharge pump cabinet;
Described switch board inside is provided with master control borad, is provided with the tensimeter, digital electric clock, action button plate and the pressure meter switch that are connected with master control borad on described switch board outside surface;
Left-hand worktable comprises moving door, base, be arranged on work top on base, be vertically arranged on the rear bearing sheet of work top rearward end, and be arranged on the horizontal outward extending top cover in rear bearing sheet top, the left-hand clamp jaw for clamping work pieces is installed on described work top; On described base, be provided with a straight line chute, on described top cover, be provided with a line slideway; The lower end of moving door is arranged in described straight line chute, and upper end is curling to be sleeved on described line slideway, and moving door can do tangential movement along described straight line chute and line slideway; Whether the end of described straight line chute is provided with limit switch, and described limit switch is connected with master control borad, close for detection of moving door; The inside of described straight line chute is provided with one for stoping the scalable pin of moving door motion, and the control end of described scalable pin is connected with master control borad.
Double safety valve testing table described in the utility model fully takes into account each details in safety valve test overall process, collection is dynamo-electric, hydraulic pressure is integrated, make the use of equipment convenient, practical reliable, test result is accurate, the efficiency that has greatly improved safety valve testing, has alleviated labour intensity.The utility model, by moving door and moving door locking device are set before worktable, makes to carry out in process at safety valve test simultaneously, and moving door cannot be opened, and has prevented the generation of maloperation, has guaranteed operating personnel's personal safety.
Further, transparent moving door glass is installed on described moving door.So arrange, can see easily the process of carrying out of safety valve test.
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing explanation
Fig. 1 is the structural drawing of double safety valve testing table described in the utility model;
In figure, the implication of each label is: left-hand worktable 1, left-hand clamp jaw 2, base 3, moving door 4, tensimeter 5, switch board 6, digital electric clock 7, action button plate 8, pressure meter switch 9, gas drive supercharge pump cabinet 10, moving door glass 11, dextrad clamp jaw 12, dextrad worktable 13, straight line chute 14.
Embodiment
As shown in Figure 1, the utility model provides a kind of double safety valve testing table, comprise left-hand worktable 1 and dextrad worktable 13, and be arranged on the switch board 6 between left-hand worktable 1 and dextrad worktable 13, the below of described switch board 6 is provided with gas drive supercharge pump cabinet 10; Described switch board 6 inside are provided with master control borad, are provided with the tensimeter 5, digital electric clock 7, action button plate 8 and the pressure meter switch 9 that are connected with master control borad on described switch board 6 outside surfaces; Left-hand worktable 1 comprises moving door 4, base 3, be arranged on work top on base 3, be vertically arranged on the rear bearing sheet of work top rearward end, and be arranged on the horizontal outward extending top cover in rear bearing sheet top, the left-hand clamp jaw 2 for clamping work pieces is installed on described work top; On described base 3, be provided with a straight line chute 14, on described top cover, be provided with a line slideway; The lower end of moving door 4 is arranged in described straight line chute 14, and upper end is curling to be sleeved on described line slideway, and moving door 4 can do tangential movement along described straight line chute 14 and line slideway; Whether the end of described straight line chute 14 is provided with limit switch, and described limit switch is connected with master control borad, close for detection of moving door 4; The inside of described straight line chute 17 is provided with a scalable pin for stoping moving door 4 to move, and the control end of described scalable pin is connected with master control borad.For the ease of viewing test situation, transparent moving door glass 11 is installed on described moving door 4.
