Problems solved by technology

Due to the frequent on-off actions of steam traps on-line, the spool is easily worn, resulting in high steam leakage rate of traditional steam traps and serious energy waste
At the same time, the online service life is short, and domestic steam traps usually need to be replaced in about one year

Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] like figure 1 As shown, the valve core 3 is installed through threads in the valve cavity of the valve body 2, and a flange 1 is welded and installed on both sides of the valve body 2. The locking washer 4 between the valve body 2 and the valve core 3 ensures the reliability of the connection.

[0022] The main principle of Venturi steam trap is to use the flow resistance caused by the different specific volumes of steam and condensed water to achieve the effect of steam blocking and drainage. The ability of the medium to pass through the flow channel is inversely proportional to the specific volume. The specific volume of condensed water and steam is about two orders of magnitude different under the same pressure, which makes the displacement of condensed water dozens of times higher than that of The displacement of steam. ...

Abstract

The invention relates to a valve design technique, and particularly discloses a venturi type steam trap. The venturi type steam trap comprises a valve body, a flange, a valve core and a locking washer, wherein the flange and the valve body are welded together, the valve core is in threaded connection to the valve body, and the connecting reliability can be guaranteed by virtue of the locking washer between the valve body and the valve core. The venturi type steam trap has the advantage of compact structure and is composed of four parts including the flange, the valve body, the valve core and the locking washer, compared with a traditional steam trap which is composed of dozens of parts, the number of the parts is greatly reduced, the stability of the steam trap is increased, the probability of failure is reduced, and the service life is long. In the same valve body, a plurality of groups of valve cores can be designed and installed, so that the displacement of condensation water is increased.

Description

Technical field [0001] The invention belongs to valve technology, and specifically relates to a steam trap used for condensation water discharge in a steam system. Background technique [0002] Steam traps are important control valves that ensure the normal operation of the steam system (heating equipment or steam pipe network), recycle condensate water, and save energy. On the one hand, it can prevent steam leakage and avoid energy waste caused by excessive steam consumption. On the other hand, it can discharge condensed water in time to avoid damage to pipelines caused by corrosion and water hammer. [0003] The energy consumed by the steam heating system occupies an important position in my country's energy consumption. The steam trap saves the heat energy of the system, not only saves coal, but also reduces the CO produced by burning this part of coal. 2 ,SO 2 And dust emissions, but also means saving auxiliary raw materials, materials, electricity, water, manpower and...
