Steam trap is an automatic valve used in steam heating equipment, steam transmission pipelines, and steam usage devices. Quickly discharge the condensed water generated by steam work from the device, prevent fresh steam leakage, and maintain the efficiency of the device at its optimal state. No form or type of steam trap is omnipotent. In order to select and install the ideal steam trap, considera...

1. Purpose of inspection: Be able to promptly detect equipment abnormalities and avoid system shutdowns and accidents. In actual production, there may be differences due to industry and process differences, but the overall requirement should be to be able to detect abnormal situations on the production site and handle them easily. This includes equipment, pipelines, instruments, control points, et...

The small hole floating ball valve has the function of automatically opening and closing pipelines to control water level. This valve is made of high-quality copper material, with a small size and easy installation, high sensitivity for use, low head loss, and no water hammer phenomenon. It can greatly improve the utilization rate of the water tower (pool). For new water towers (pools), due to the...

Low temperature bearings are not bearings that operate stably in high temperature environments, but rather refer to the design of special materials and structures to reduce friction coefficient, thereby reducing friction and heat generation, and maintaining low temperature during long-term operation of bearings. Bearings with operating temperatures below -60 ℃ are low-temperature bearings. Mainly ...

1. Introduction to Y-type Filter Y-type filters are an indispensable filtering device in pipeline systems that transport media. Y-type filters are usually installed at the inlet of pressure reducing valves, relief valves, constant water level valves, or other equipment to remove impurities from the media and protect the normal use of valves and equipment. The Y-type filter has the characteristics ...

Many people prioritize stainless steel pumps when pumping seawater or saturated salt water. They feel that the stainless steel material is durable and does not require much maintenance, but it is faster to detect damage when used, and the stainless steel pump is severely corroded. Seawater is a very complex multi-component aqueous solution. The main elements in seawater include Na ions, K ions, CL...

Plug valve, a valve that uses a plug body with a through hole as the opening and closing component. The plug body rotates with the valve stem to achieve opening and closing action. A small plug valve without packing is also known as a "cock". The plug body of the plug valve is mostly a conical body (also known as a cylinder), which forms a sealing pair in conjunction with the conical hole surface ...

A check valve, also known as a check valve, is an automatic valve that relies on the pressure of the flowing medium in the pipeline to push the valve disc to close and open the valve. When the medium stops flowing, the check valve disc closes, effectively preventing the medium from flowing back in the pipeline, which plays a significant role in ensuring the safety of the pipeline. Check valves can...
