Drain valve based on safety improvement

Abstract

The invention discloses a drain valve based on safety improvement. The drain valve based on safety improvement comprises a valve body assembly, a control assembly and mounting assemblies, the valve body assembly comprises a shell, a fastener arranged on one side of the shell, a water inlet piece arranged on the top of the shell, and a water outlet piece arranged at the bottom of the shell. The control assembly is arranged in the shell and comprises a valve seat arranged on the inner bottom wall of the shell, a valve clack arranged on the top of the valve seat, a flow guide part arranged in the valve seat and a floating ball part arranged on the top of the valve clack. The mounting assemblies are arranged on the inner bottom wall of the shell and located on the two sides of the valve seat. According to the drain valve based on safety improvement, through the arrangement of the control assembly and the mounting assemblies, the disassembly, assembly and maintenance efficiency of the drain valve is higher, meanwhile, the drain valve is more convenient to use, then through the arrangement of a connecting assembly, the stability of the drain valve is higher when the drain valve is connected to a pipeline, a certain buffer space is provided, the probability of breakage of the joint between the drain valve and the pipeline is greatly reduced, and the safety is higher.

Description

technical field [0001] The invention relates to the technical field of steam traps, in particular to a steam trap based on improved safety. Background technique [0002] The function of the steam trap (referred to as the trap) is to automatically remove non-condensable gases such as steam condensed water and air in the heating equipment or steam pipeline, and no steam leaks. Evenly supply heat, make full use of the latent heat of steam to prevent water hammer in the steam pipeline. There are many types of traps, each with different performance. When selecting a trap, first of all, its characteristics should be selected to meet the optimal operation of the steam heating equipment, and then Considering other objective conditions, it is correct and effective to choose the trap you need. The traps in the prior art are generally installed in the air or fixed on the wall by screws. During the use process, it is easy to cause the pipeline to be overstressed and cause large deforma...

Problems solved by technology

[0002] The function of the steam trap (referred to as the trap) is to automatically remove non-condensable gases such as steam condensed water and air in the heating equipment or steam pipeline, and not to leak steam. Because the trap has the function of blocking steam and draining water, it can make the steam heating equipment Uniform heat supply, make full use of steam latent heat to prevent water hammer in the steam pipeline, there are many types of steam traps, each with different performance, when selecting a steam trap, firstly choose its characteristics to meet the best operation of the steam heating equipment, and then Considering other objective conditions, it is correct and effective to choose the steam trap you need. The steam traps in the prior art are generally installed in the air or fixed on the wall by screws. During the use of the pipe, it is easy to cause the pipe to be subjected to excessive force and cause large deformation, resulting in breakage, etc., but the way of installing the trap on the wall has less room for error, and the trap needs a certain buffer space during use. In order to avoid the breakage of the connection between the trap and the pipeline, this method will lead to low safety during the use of the trap, and there will be a lot of inconvenience
