Description
(1) technical field
The utility model relates to a kind of device that can carry out long run test from the certain limit negative pressure to malleation, relates in particular to utilize pressurized air to finish vacuum take-off test, the negative pressure oil tanker vacuum pressure valve testing table to malleation tightness test, malleation take-off test simultaneously.Belong to and build the ship technical field.
(2) background technology
Oil tanker and chemical tanker repairing amount are more and more in recent years, when repairing at every turn, on the ship all vacuum pressure valves of oil cargo tank all need basically to disassemble, cleaning, maintenance and repair, And carries out close property and breathes the effectiveness test at internal field, workshop testing table one by one.(0.007～0.021MPa) keeps sealing air tight in certain vacuum or range of pressure values to require vacuum pressure valve during test, and in case exceed the essential smooth opening in time of this scope, thereby guarantee that oil cargo tank is relative with the external world isolated, guarantee that simultaneously the cargo tank structure is not subjected to excessive pressure or vacuum.
Originally the vacuum pressure valve test unit that uses adopts the electronic scraper plate vacuum pump of a 5.5KW, by handling the import and export and the flow of four stop valve control vacuum pumps, thereby provide test pressure or vacuum to vacuum pressure valve, there is weak point in this device: operation control inconvenience, often to start, close electric vacuum pump, four stop valves of frequent operation are controlled test pressure or vacuum simultaneously, regulate difficulty of control ratio, do not note slightly, liquid will be gone out in " U " shape glass-tube manometer, and liquid level is set in water filling again then; Scraper plate vacuum pump suction inlet must often add water, otherwise can cause heating and inefficacy; Vacuum pump directly is connected with pipe with vacuum pressure valve, there is not the air receiver pressure accumulation, check that the airtight situation before the vacuum pressure valve take-off is very difficult, in case and take-off, the pipeline inner pressure fluctuation is bigger, can not clearly illustrate the take-off value, so can not finely satisfy the actual tests requirement, the vacuum pressure valve of ship test sometimes needs one day even several days time; Because it is very low that vacuum pressure valve is tested required pressure, uses a Motorized vacuum pump efficiency low specially, the energy consumption height, noise is big, oil-sealed rotary pump maintaining inconvenience simultaneously.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of easy oil tanker vacuum pressure valve testing table is provided, and it is simple in structure, and is easy to operate, and test findings is accurate, and energy-conserving and environment-protective are easy to maintenance.
The purpose of this utility model is achieved in that a kind of oil tanker vacuum pressure valve testing table, comprise ejector and air receiver, ejector import butterfly valve and ejector exit butterfly valve are installed on the described ejector, described ejector import inserts pipeline pressurized air, suction inlet inserts air receiver, the logical atmosphere of outlet, two vacuum pressure valve mounting interfaces are set on the described air receiver, two vacuum pressure valve mounting interfaces link to each other with two vacuum pressure valves by two joint flanges, two joint flange dish valves are installed on described two joint flanges, a pressure vacuum gauge and " U " shape glass-tube manometer are installed on the air receiver, on two tops of " U " shape glass-tube manometer two little buckets are set respectively, also are provided with a cover blow-out disc on the air receiver.
Testing table directly utilizes low pressure line pressurized air in the workshop, through large-flow jet device and the conversion of control butterfly valve, through a 1m
3About air receiver provide test air pressure or vacuum to vacuum pressure valve.Test pressure is after the expansion box buffering, and it is more stable, clear that test pressure is shown, is convenient to observation and inspection, and operation control is also grasped easily; Two vacuum pressure valve mounting interfaces are set on the air receiver, and two dish valves are set, when a vacuum pressure valve is tested, can carry out the dismounting of another vacuum pressure valve like this, experiment work can uninterruptedly be carried out continuously, improve experimental examination efficient; Because test pressure very low (about 2100mm water column), vacuum pressure valve and the method that adopts general pressing plate to connect fast being connected of testing table, so both be beneficial to fast assembling-disassembling, raised the efficiency, and can adapt to the connection of most of different model vacuum pressure valves again, avoided often changing joint flange; A pressure vacuum gauge and " U " shape glass-tube manometer are installed on the air receiver, make and check that observation is convenient directly perceived, on two tops of " U " shape glass-tube manometer two little buckets are set respectively, cause the test pressure fluctuation in case be used for preventing misoperation, can automatically reset after water level overflows in " U " shape glass-tube manometer, avoid water filling again that the trouble of liquid level is set; For guaranteeing safety, a cover safety anti-explosive film is set on the air receiver; Because test vacuum tightness less (approximately 700mm water column), flow is bigger, so ejector adopts big traffic type, thereby improves the pressurized air service efficiency.
The beneficial effects of the utility model are:
Adopt above-mentioned oil tanker vacuum pressure valve testing table, work efficiency significantly improves, and operates very easyly, and test findings is clear, and it is convenient to check.Save kinetic energy simultaneously, reduce noise, simple in structure, easy to maintenance.
