Using WCB material.Design with full consideration of corrosion allowance,Minimum shell wall thickness, pressure and temperature class
The U-shaped flow channel design ensures that the inside of the valve body is in a water-sealed state
Micron-level high-precision valve seat and valve core ensure reliable closing system and no steam leakage
Small holes are left on the upper part of the bucket to remove air and other non-condensable gases to prevent the occurrence of steam lock the valve
Effectively prevent pipeline impurities from entering the valve Make sure the trap valve is working properly
Prevents water hammer from damaging internals. Also suitable for super-heated steam environments
Inverted bucket Steam traps are widely used in steam transmission pipelines, process heat tracing, jacketed heating kettles tank, reboil-ers and other equipment due to their safety, reliability, energy saving, long life, low temperature resistance and other characteris
The technical advantages of VMV traps:Unique and reasonable structure, high-preci-sion internal parts
VMV steam trap design has fully considered factors
such as shell strength, pressure and temperature
grade, casting manufacturability, tightness of valve
plug and seat closure, impact caused by water and
vapor mixing, and the strength of valve cover gasket
is affected by low temperature environment and other
factors .
Inverted bucket steam traps work on the difference in density between steam and condensate. When the bucket is full of condensed water and non-condensable gas,
the exhaust hole on the upper part of the bucket
removes the non-condensable gas, the bucket loses
buoyancy and drives the valve core to move down, the
trap opens to drain, and when steam enters the bucket after draining, the bucket floats to drive the valve
The core closes the trap.
The great advantages of the inverted bucket trap are
high back pressure rate, long life, reliable action,convenient maintenance and on original steam leakage.
.
The inverted bucket steam trap is intermittently drained,the subcooling degree is 5-10℃, and the back pressure rate is over 85% (back-end pipeline pressure/steam pressure). In general, the safety factor is 2-3 times when selecting, and 5-8 times for air separation units and drying cylinders. The amount of condensed water and the differential pressure of the steam-using equipment are important indicators for model selection. For the same type of steam trap, the displacement increases with the increase of the differential pressure. See the details on displacement curve.
Special reminder: Please do not mistakenly think that a trap with a large diameter has a large displacement.
The inverted bucket trap is installed horizontally at the bottom of the pipeline or equipment. The basic configuration of the trap is shown in the figure above.
When the pipeline is superheated steam, a check valve must be installed to prevent the failure of the trap due to the superheated steam drying out the water seal in the trap.
