Description
Technical Field
The utility model relates to a device, in particular to a device for testing pressure of an air safety valve, and belongs to the technical field of hydraulic generator overhaul fixture design and manufacture.
Background
In the air supply facilities such as a medium-pressure air system, a low-pressure air system and a speed regulator pressure system which are configured in a hydroelectric power station, a plurality of air safety valves are required to be installed to serve as the last defense line for providing pressure air for the pressure container, the function is particularly important, but in the use process, the air safety valves can normally and accurately act when overpressure occurs, and the air safety valves cannot malfunction when the pressure is lower than a set value, so that the air safety valves of the pressure container need to be overhauled throughout the year. In the prior art, the safety valve is detached firstly, and then the safety valve is sent to the inspection mechanism for inspection, and the safety valve is far in the way of sending inspection back and forth, and the set value is often drifted due to jolting, so that the condition that the safety valve acts when the rated pressure is not reached after the pressure is built is caused, and the construction period and the safety operation of the pressure container are seriously influenced. Accordingly, there is a need for improvements in the art.
Disclosure of Invention
The technical problems to be solved by the utility model are as follows: how to verify the disassembled air safety valve of the pressure vessel on site, ensure that the set value of the air safety valve after the back-loading does not drift, reduce the workload of back-and-forth disassembly, pressure building and pressure relief, ensure the reliability of the air safety valve and ensure the safe and stable operation of the pressure vessel.
The utility model is realized by the following technical scheme: the utility model provides an air relief valve pressure testing device, which comprises a frame, be equipped with two at least flanges in its characterized in that frame, the flange upper end links to each other with the air relief valve that awaits measuring, the lower extreme is connected with the air feed branch pipe of taking the valve on it, the air feed branch pipe links to each other with a tee bend, one in the tee bend link to each other with the air feed house steward one end that is connected with the manometer on it, the air feed house steward other end links to each other with the coupling, the coupling passes through the connecting pipe and links to each other with the air pump, so that after the control valve intercommunication air pump, can send into the air relief valve that awaits measuring, make it pressure boost, when the data on the manometer is close the settlement pressure value of air relief valve, stop the air pump air feed, when the pressure data of manometer is unchangeable, it is normal, no trouble, can continue to use, otherwise can't use, need to replace or maintain.
And the air supply main pipe is provided with a control valve to control whether the air pump supplies air or not.
The frame comprises a rectangular frame, a horizontal top plate arranged at the top of the rectangular frame, and flanges and pressure gauges are arranged on the horizontal top plate so as to facilitate operation.
The utility model has the following advantages and effects: by adopting the technical scheme, the air pump is conveniently communicated with the pressure gas pump through the control valve, and then the pressure gas can be fed into the air safety valve to be detected to boost the pressure gas, when the data on the pressure gauge is close to the set pressure value of the air safety valve, the air pump is stopped for gas supply, and when the pressure data of the pressure gauge is unchanged, the air safety valve is normal and has no faults, and can be continuously used, otherwise, the air safety valve cannot be used and needs replacement or maintenance.
Drawings
FIG. 1 is a schematic diagram of the structure of the present utility model.
Detailed Description
The utility model is further described below with reference to the accompanying drawings.
The utility model provides an air safety valve pressure testing device, which comprises a frame 1, wherein two flanges 2 are arranged on the frame 1, the upper ends of the two flanges 2 are respectively connected with corresponding air safety valves 3 to be detected, the lower ends of the two flanges are respectively connected with an air supply branch pipe 5 with a valve 6 on the upper end, the air supply branch pipe 5 is connected with a tee joint, one of the tee joints is connected with the inner end of an air supply main pipe 7 with a pressure gauge 4 connected thereon, the outer end of the air supply main pipe 7 is connected with a pipe joint 9, and the pipe joint 9 is connected with an air pump 12 through a connecting pipe 10; the air supply main pipe 10 is provided with a control valve 11 for controlling whether the air pump 12 supplies air or not; the frame 1 comprises a rectangular frame, a horizontal top plate 8 arranged at the top of the rectangular frame, and a flange 2, a pressure gauge 4 and an air safety valve 3 to be detected are arranged on the horizontal top plate 8 so as to be convenient to operate.
When in operation, the device comprises: after the control valves 6 and 11 are communicated with the air pump 12, the pressure gas can be sent into the air safety valve 3 to be detected, the pressure gas is pressurized, when the data on the pressure gauge 4 is close to the set pressure value of the air safety valve 3, the control valve 11 stops the air pump 12 for supplying air, when the pressure data of the pressure gauge 4 is unchanged, the air safety valve 3 is normal and has no fault, and can be continuously used, otherwise, when the pressure data of the pressure gauge 4 is reduced, the air safety valve 3 has a fault, and replacement or maintenance is needed.
