Performance testing equipment of pressure regulator of bottled liquefied petroleum gas and application method thereof

Abstract

The invention discloses performance testing equipment of a pressure regulator of bottled liquefied petroleum gas and an application method thereof. The existing testing equipment of the pressure regulator has the disadvantages of low automatic degree, time wasting of mounting a test piece and time wasting of replacing a tool and a clamp. The performance testing equipment comprises an inner structure and an outer structure, wherein the inner structure is connected with the outer structure through an electric wire; the outer structure comprises a vertical operation platform, left and right air exhausting fans, an air inlet pressure meter, an air outlet pressure meter, a liquid crystal display, a roughly-adjusting decompression valve, a finely-adjusting decompression valve, a test gas inlet, a test gas outlet, an integrated clamp, an operation platform, a Siemens PLC (Programmable Logic Controller), a pressure regulator driving module, an industrial personal computer and a wiring board; and the inner structure comprises an air source decompression valve, a primary decompression valve, a filter, No.1-No.9 solenoid valves, a pressure regulator, an electric control flow valve, a large-range flow meter, a clamp gas solenoid valve, a one-way valve, a middle-range flow meter and a small-range flow meter. The testing equipment disclosed by the invention has the advantages of being rapid and simple in installation and high in testing precision, and can better guarantee the accuracy of the static property detection of the pressure regulator, and the product quality.

Description

technical field [0001] The invention belongs to the technical field of flow testing equipment, and in particular relates to a performance testing equipment for a bottled liquefied petroleum gas pressure regulator and a use method thereof. Background technique [0002] Household bottled liquefied petroleum gas pressure regulators are products with a production license that are related to the safety of people's lives and property. The pressure regulator is used together with stoves and water heaters to ensure safe combustion. At present, there is a serious problem in the domestic pressure regulator industry: the pressure of products sold on the market is generally high and the flow rate is difficult to be accurate, and the pass rate is extremely low (less than 10%). However, the current test equipment for voltage regulators has a low degree of automation, time-consuming installation of test pieces, and time-consuming replacement of tooling and fixtures. In particular, one dev...

Problems solved by technology

At present, there is a serious problem in the domestic pressure regulator industry: the pressure of products sold on the market is generally high and the flow rate is difficult to measure, and the pass rate is extremely low (the pass rate is less than 10%)

However, the current test equipment for voltage regulators has a low degree of automation, time-consuming installation of test pieces, and time-consuming replacement of tooling and fixtures. In particular, one device can only test one performance index, resulting in low efficiency of the overall test. The development of a fixture completes all performance tests. , Faster and more convenient pressure regulator flow test equipment, process and method, to meet the higher demand of pressure regulator manufacturers, is an effective way to improve the production efficiency of pressure regulator products
