Abstract
The invention discloses a testing device of a transformer pressure relief valve. The testing device comprises an air barrel, an air inflation pipe, a pressure meter and testing bases. The air inflation pipe is connected on the upper portion of the air barrel, the pressure meter is connected at the top end of the air inflation pipe, one side of the air inflation pipe is connected with an air inflation mouth with a one-way valve, and a plurality of testing bases used for allowing the pressure relief valve to be placed are distributed on the upper portion of the air barrel. When the testing device is used, the pressure relief valve to be tested is placed on the testing bases to enable the bearing capacity test of pressure to be carried out. The testing device of the transformer pressure relief valve is simple in testing method, practical and reliable, multiple pressure relief valves can be tested at one time, and time and labor are saved.
Description
Technical field
The present invention relates to a kind of pick-up unit, relate in particular to a kind of verifying attachment of transformer pressure relief valve.
Background technology
The transformer pressure relief valve is contained on the oiling transformer mouth, is the safety feature of protecting transformer, can avoid fuel tank distortion or explosion.When transformer inside had an accident, the oil in the fuel tank was vaporized, and produces a large amount of gas, and tank internal pressure is sharply raise, and when pressure was elevated to the relief valve opening pressure, relief valve rose rapidly in Zms and opens, and in time discharges the overvoltage in the transformer.When pressure dropped to the closing presure value of valve, valve reliably cut out again, made to keep malleation in the fuel tank forever.Mostly the transformer pressure relief valve is outsourcing piece, at present, owing to lack the quality detection device of practical and reliable pressure relief valve, this product stock up can't check whether qualified, cause in use normally open and close to discharge the oil tank of transformer internal pressure, cause power transformer product quality accident to occur.
Summary of the invention
The purpose of this invention is to provide a kind of simple to operate, the verifying attachment of practical and reliable transformer pressure relief valve.
The objective of the invention is to be achieved through the following technical solutions, the verifying attachment of this pressure relief valve comprises inflator, gas-filled tube, tensimeter, check seat, described inflator is airtight cylindrical shape, the top of described inflator is connecting gas-filled tube, the top of described gas-filled tube is connected with tensimeter, one side of described gas-filled tube is connected with the charging connector of band retaining valve, the distributing check seat of a plurality of placement force relief valves of the top of described inflator.
During use, at first pressure relief valve to be tested is placed on the check seat, make pressure relief valve and the periphery of check seat be in sealing state, inflate in inflator by charging connector then, pressure size in the inflator is measured by the tensimeter that is positioned at the gas-filled tube top, also then detect the size that pressure relief valve bears pressure between just, namely whether qualified.
Beneficial effect of the present invention:
1, the method for inspection is simple, and is practical reliable; 2, once can check many pressure relief valves, time and labour saving.
Description of drawings
Describe embodiments of the invention in detail below in conjunction with accompanying drawing
Fig. 1 is front view of the present invention
Fig. 2 is vertical view of the present invention
Among the figure: 1, inflator 2, gas-filled tube 3, tensimeter 4, check seat 5, charging connector
Embodiment
Embodiment: as shown in Figure 1, 2, the verifying attachment of this pressure relief valve comprises inflator 1, gas-filled tube 2, tensimeter 3, check seat 4, inflator 1 is airtight cylindrical shape, the top of inflator 1 is connecting gas-filled tube 2, the top of gas-filled tube 2 is connected with tensimeter 3, one side of gas-filled tube 2 is connected with the charging connector 5 of band retaining valve, the distributing check seat 4 of a plurality of placement force relief valves of the top of inflator 1.During use, at first pressure relief valve to be tested is placed on the check seat 4, make pressure relief valve and the periphery of check seat 4 be in sealing state, inflate in inflator 1 by charging connector 5 then, pressure size in the inflator 1 is measured by the tensimeter 3 that is positioned at gas-filled tube 2 tops, also then detect the size that pressure relief valve bears pressure between just, namely whether qualified.
Claims (2)
1. the verifying attachment of a transformer pressure relief valve, the verifying attachment that it is characterized in that this pressure relief valve comprises inflator, gas-filled tube, tensimeter, check seat, the top of described inflator is connecting gas-filled tube, the top of described gas-filled tube is connected with tensimeter, one side of described gas-filled tube is connected with the charging connector of band retaining valve, the distributing check seat of a plurality of placement force relief valves of the top of described inflator.
