Testing system of steam hydrophobic valve type

Abstract

The invention discloses a testing system of a steam hydrophobic valve type, and the system comprises a high-pressure tank device which is used for providing steam with the specific testing pressure and temperature and hot condensed water for a tested drain valve, steam and hot condensed water pipes which are connected between the high-pressure tank device and the front end of the tested drain valve, a discharge pipe which is disposed in the direction of the rear end of the tested drain valve, a pipe-type telescoping joint which is connected between the rear end of the tested drain valve and the discharge pipe, and a monitoring device which is used for monitoring the on / off of the tested drain valve. The monitoring device comprises a first sight glass which is disposed between the pipe-type telescoping joint and the rear end of the tested drain valve. The first sight glass moves along with the stretching and drawing of the pipe-type telescoping joint. The system can achieve automatic control, and is used for the type tests of different types of stream drain valves in different nominal sizes.

Description

technical field [0001] The invention relates to a steam trap test system, in particular to a steam trap type test system. Background technique [0002] The energy consumed by the steam heating system occupies an important position in my country's energy consumption. According to statistics, at least 700 million tons of coal are used in steam heating systems in my country every year, accounting for about 1 / 3 of the country's coal production. However, the utilization rate of steam in our country is only about 30%, there is a huge waste, and the energy saving potential of the steam heating system is huge. As an energy-saving product, steam traps are widely used in steam heating systems such as steam heating equipment, pipes, heaters, radiators, etc., to automatically remove condensed water, air and other non-condensable gases, and to prevent steam leakage. In order to achieve energy-saving and environmental protection purposes such as improving heat exchange efficiency, reduc...

Problems solved by technology

[0023] The five sets of test devices recommended by GB / T12251-2005 "Test Methods for Steam Traps" need to be equipped with different flange joints for the type tests of steam traps of different models, specifications, types, and structural lengths, and the test process is extremely different. Convenience, with increased risk of compromising test safety
