Refrigerant leakage caused by cold storage refrigeration accident valve or the culprit

refrigerator frequent accidents refrigeration valve or the culprit

on August 7, 2013, anhui province dacheng food co. , LTD. Cold storage liquid ammonia leakage occurs, one minor injuries, accident investigation because of liquid ammonia leakage of valve failure, leakage of liquid ammonia, continuous dilution caused an accident.

in media reports, the cold storage safety accidents happen in all parts of the country, such as the recent yantai a cold storage of pipeline caused by breakage of ammonia leakage of the valve. Hubei is given priority to with processing and frozen aquatic products enterprise sudden ammonia leakage accident, according to the survey is due to the company a refrigerator valve core is suddenly loose, leakage of ammonia by vacuum room of pipe aperture, spread into the wall of packaging workshop, leading to the the company has more than one hundred and thirty employees in hospital inspection and treatment.

in numerous accident investigation, the cause of ammonia leakage, except for a handful of people error to the device itself is the reason: in the process of normal use, due to the years without repair equipment aging caused leakage accident, which is the equipment failure; The valve leakage, usually because of loose valve axis, air tightness is not good, leakage of ammonia along the axis; Weld aging, after a long period of use, some weld on the pipeline aging, causing ammonia leakage; Flange gasket, aging equipment oil prone to corrosion of pipeline in the flange rubber gasket, washer aging caused leak.

low-quality valves to project traders bring great trouble

although fluorine systems rarely appear the safety accidents such as leak, but due to use inferior valves for cold storage engineering annoyance creeping.

inferior valves generally adopts the material composition, high content of impurities, A lot of waste is recycled smelting) , the strength and impermeability is very important for valve parts, inferior valves tend to be informal manufacturers through the use of seals, reduce the material thickness to reduce the cost, make a profit.

inferior valve with high quality valve parts of the most obvious difference is that whether the leak, use inferior valve parts, will produce a lot of potential safety problems and waste systems, light of cold storage of the user to shut down stopped, there is no guarantee that food quality; Or may cause safety accidents.

quality valves in the market price difference is big, low valve parts, general is a high-grade valve 30 - price 50%, professionals pointed out: 'the high quality valves can be normal operation after installation and debugging for years or even decades, inferior valves may not warranty period began to rust, leakage, coil burned. '

good valves to have what condition?

in the refrigeration system, cooling valve is one of the most overlooked element, but it plays a vital role. Is there, opening, the key to be reckoned with, must cause enough attention, so choose a suitable, high quality and stability of the valve is particularly important.

valve as well as a need to have what condition? Reporter special interview domestic leader in the field of valve piece - — Zhejiang sanhua refrigeration group Marketing Department minister Meng Xinyang for details.

Meng Xinyang introduction, good valve product must have one of the most important features: no leakage, which is to guarantee the safety of its use. 'In the pursuit of the security performance of the valve parts, three flower series product innovations, such as we are on the verge of a comprehensive listing of a new generation of thermal expansion valve RFKH have replaced internal copper capillary tube with stainless steel materials, stainless steel strength is higher, it is not easy to break, to guarantee the reliability of the expansion valve, and also has a lot of improvement to product performance. '

' on the market a lot of piston solenoid valve life are in the tens of thousands of times or so, and three flowers piston solenoid valve can be run at least 1 million times. Unable to distinguish the merits of the solenoid valve performance for short periods of time, but after used more frequently, the differences came out, three solenoid valve without a gasket seal, but make it totally enclosed, it solves the valve product one of the key questions - — Leakage. 'Meng Xinyang introduction, three flowers for product reliability verification is obsessively, thermal expansion valve, for example, since launch, market feedback about reliability is 0.

air conditioner capacitor are among the best and the long known , which plays an essential part in automatic manufacturing.

A detailed plan must be developed if we hope to reach your profitability goal. Once we have a certain figure in mind, Hangzhou E cool refrigeration Co.,Ltd and our staff need to determine all the steps necessary to reach that goal and act on them.

Oftentimes for Hangzhou E cool refrigeration Co.,Ltd, this means look for the impact. Giving people something to believe in, that emotional connection, that's what refrigerant gas.
