Abstract
The utility model relates to an online pressure vessel safety valve calibration system and belongs to the field of pressure vessels. According to the online pressure vessel safety valve calibration system, a three-way pipe is connected between a pressure vessel and a safety valve, three joints of the three-way pipe are respectively connected with a first valve, the safety valve and a valve, the valve is connected with the pressure vessel through a pipeline, the first valve is connected with a quick-action male connector through a section of straight pipeline, the quick-action male connector and a quick-action female connector are connected with an air pump through a section of pipeline after being in butt joint, a joint of the air pump is connected with a nitrogen cylinder through the pipeline, and a pressure gauge is arranged on the straight pipeline. The online pressure vessel safety valve calibration system can be directly connected to the pressure vessel to detect the pressure of the safety valve online and is simple in structure and convenient in operation, a complicated process of safety valve removing is omitted, and medium in the pipeline can be effectively prevented from discharging to the air to pollute the environment and bring harm to people.
Description
Technical field
The utility model relates to a kind of pressure vessel relief valve on-line testing system, belongs to pressure vessel field.
Background technology
Pressure vessel is the common a kind of equipment of chemical enterprise, and safety valve is main element on pressure vessel, plays the effect of protection PVP (Pressure Vessels and Piping) safety, prevents great industrial accident.Safety valve principle of work is in not by any external force situation, utilizes tank internal pressure by medium in spool jack-up drain tank, to prevent the over proof safety value of pressure.After pressure recovers normally, valve is closed voluntarily and is stoped medium to continue to flow out.Safety valve is under long-term work, and its performance particularly set-pressure can change, and will cause safety valve opened by pressure or time seat in accordance with regulations, causes production safety hidden danger and contaminated environment.According to national relevant regulations, to safety valve, must regularly detect set-pressure.First the method for detection check disassembles safety valve above tank body now, and then carries out verification detection, this method complicated operation, and workload is large, and easily causes the medium in pipeline to be let out in air, and contaminated environment, the personnel that bring injure.
Utility model content
The purpose of this utility model be to provide a kind of can direct-on-line verification safety valve, remove the loaded down with trivial details operation of dismounting safety valve from, pressure vessel relief valve on-line testing system simple in structure, easy and simple to handle.
Technical solution is:
The utility model comprises: pressure vessel, safety valve, a three-way pipe is installed between pressure vessel and safety valve, three joints of three-way pipe connect respectively the first valve, safety valve and valve, valve is connected with pressure vessel by pipeline, the first valve is connected with quick male joint by straight-run of pipe road, male joint is connected with air pump by one section of pipeline with after quick female joint docking fast, and the joint of air pump is connected with nitrogen cylinder by pipeline, on described straight pipeline, establishes tensimeter.
Described quick male joint is provided with sealing dust-proof cover.
The utility model is owing to having adopted above-mentioned technology, and the good effect that makes it compared with prior art to have is:
The utility model can be connected directly to pressure vessel the pressure of safety valve is detected online, simple in structure, easy and simple to handle, remove the loaded down with trivial details operation of dismounting safety valve from, and effectively prevent that the medium in pipeline from letting out in air, and contaminated environment or the personnel that bring injure.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, further illustrate embodiment of the present utility model.
Shown in Figure 1, the utility model comprises air supply unit and detecting unit; Described air supply unit comprises: air pump 8, nitrogen cylinder 12; Described detecting unit comprises pressure vessel 1, safety valve 5; Described air supply unit is connected with described detecting unit, and pressure is provided to described detecting unit; The nitrogen cylinder 12 of described air supply unit connects air pump 8; Between the pressure vessel 1 of described detecting unit and safety valve 5, a three-way pipe 4 is installed, 4 three joints of three-way pipe connect respectively the first valve 9, safety valve 5 and valve 3, valve 3 is connected with pressure vessel 1 by pipeline 2, and the first valve 9 is connected with quick male joint 11 by straight-run of pipe road 10; Between described air supply unit and detecting unit, by quick male joint 11, be connected with quick female joint 7, female joint 7 is connected with the air pump 8 on described air supply unit by one section of pipeline fast; On described straight pipeline 10, establish tensimeter 6, described quick male joint 11 is provided with sealing dust-proof cover.
When not detecting, the first valve 9 is closed, use a dust cap by quick male joint 11 sealings simultaneously, prevent that dust from entering pipeline the inside, when need carry out verification safety valve 5, closes valve 3, open the first valve 9, quick male joint 11 is connected with quick female joint 7, air pump 8 is started working the gas High voltage output in nitrogen cylinder 12 simultaneously, through quick male joint 11 and female joint 7 fast, the first valve 9 is until safety valve 5, the value of observation safety valve 5 tensimeter 6 when opening.Verification is complete directly to be unloaded quick female joint 7, and dust cap is covered, and has completed checking process.
