High-displacement floater type trap valve

Abstract

The invention discloses a high-displacement floater type trap valve which comprises a valve cover, a valve body, a floater, a water inlet and a water outlet. The valve cover is arranged on the valve body, and the floater is arranged in the valve body. The valve further comprises a filter screen arranged below the water inlet. An in-valve water inlet is arranged between the filter screen and the floater, the filter screen is fixed in the valve body through a filter screen screw plug, an air return plate is arranged on the valve body between the water inlet and the floater, and a plurality of air return holes are formed in the air return plate. The floater type trap valve can solve the air blocking problem in work and improve the displacement. The high-displacement floater type trap valve has the advantages of being advanced in manufacture process, stable in performance, good in energy saving effect, long in service life and high in cost performance of free floater type trap valves, further solves the air blocking problem in work, increases flow, does not cause the air blocking problem and can adapt to various different conditions and environments. Meanwhile, the filter screen is easy to wash, simple and convenient.

Description

technical field [0001] The invention relates to the field of steam traps, in particular to a large displacement ball float type steam trap. Background technique [0002] Steam trap is an automatic valve used on steam heating equipment and steam pipelines, which can automatically remove condensed water, air and other non-condensable gases in pipelines and steam-using equipment, and can prevent steam leakage. [0003] In the existing technology, the free-floating ball trap uses the principle of density difference between condensed water and steam, and places the hollow floating ball unconstrained inside the valve body of the trap as the disc to complete the switching function. It can rise or fall freely, so that the trap can be opened and closed. The free float type steam trap has the advantages of advanced manufacturing technology, stable performance, good energy saving effect, long service life and high cost performance, so it has been widely used. [0004] But the prior a...

AI Technical Summary

Problems solved by technology

[0005] Once the water film is formed, under the pressure of the water flow, the internal and external air pressure will be unbalanced, so that no amount of water can enter the valve body, and the air blockage problem will occur during the working process. When the air blockage problem occurs to a certain extent, it will Seriously affect the normal operation of the entire steam trap and reduce the heat exchange efficiency of gas equipment, so there is an urgent need for a float type steam trap that can solve the problem of air blocking during work and increase the displacement
