Abstract

The invention provides a kind of drain valve that relies on capillary force and gravity work, it is used the tubule that the material compatible with working medium make or inserts capillary materials and make in thicker pipe.Have and do not consume energy, can make steam work system sealing system reliability height, hydrophobic power is big, working pressure is high, low cost and other advantages.Can be used for making various high-quality steam engines and vapor pump.

Description

A kind of drain valve that does not consume energy and uses thereof

The present invention relates to a kind of drain valve.

It is trivial that the working medium of heat pipe (ginseng horse with works such as pool " heat pipe ") leans on capillary force to flow to high pressure from low pressure area, invents out by the drain valve of capillary force work in view of the above and use it for new hot machine and heat pump.

The purpose of this invention is to provide a kind of drain valve that does not consume energy.

Its solution is, use the material compatible to make to insert capillary materials in tubule or the thicker pipe with working medium such as metal is arranged net or the thin slice rolled along the ripple direction as valve body.Require between capillary materials and tube wall heat conduction good, size is to satisfy hydrophobic speed and can proper functioning be as the criterion.Valve is arranged vertically the hydrophobic loop of access, when steam in valve from the zone of high pressure when low pressure area flows, very fast by be enclosed on slender pipeline with good traditional performance or the capillary materials in the valve pipe, under capillary force or action of gravity, absorbed to the zone of high pressure flowing liquid.Further, increase absorption or the transmittability of valve body by valve is dispelled the heat, increase the working pressure and the power of valve steam and heat energy thereof.

Accompanying drawing 1 is drawn one embodiment of the present of invention, and this is a vapour-liquid separation type heat pipe, makes with glass.Divide four parts that are interconnected up and down.The right is a drain valve 1, the telophragma tubular portion helps the valve working stability, during heat pipe work, the bottom of valve can be seen a crest shape vapour-liquid interface 2(who is stretched over the heating position and amplify in the right), the capillary tube of getting φ 2 is the valve pipe, per minute can be hydrophobic 1 milliliter under 1 atmospheric working pressure, crest downforce gradient can reach 0.2 barometric pressure/centimetre.Valve pipe lower diameter becomes big and the smooth connection of heat pipe hot junction from top to bottom gradually; Left side frame of broken lines 4 is the heat pipe steam passage, the heat pipe cold junction above steam passage connects; Having the liquid collecting plane in the cold junction, is that low voltage terminal links to each other with the upper end of valve.The lower end of valve is called high voltage terminal.

Thereby can fall end vapour-liquid interface height to valve body heat radiation makes the valve of same length can obtain higher working pressure.Can be by using bigger valve pipe such as the flat cross section valve pipe of surface area, the parallel connection of many valves, on the valve pipe, adorn various radiators such as radiating fin or heat-pipe radiator or adopt the mode that on tube wall, keeps the moisture content supply to make its evaporator strip walk heat to realize.But avoid waste to equipment heat energy.

Optionally, among Fig. 1 embodiment down, in, last three parts can be by the heat pipe hot junction, steam passage and heat pipe cold junction change boiler, steam turbine and the condensation chamber of steam engine into or change boiler, sparger and the condensation chamber of vapor pump into.Also can change the steam work system of other sealing into.

The present invention have energy-saving and water-saving, reliable, can be with the pipeline integral production, power is big, operating pressure is high, applicability is wide, cost is low, can make the advantages such as steam work system sealingization and high quality.

Claims

1, a kind of drain valve that relies on capillary force, action of gravity work done, constitute by pipeline or capillary materials, it is characterized in that: 1. steam in valve from the zone of high pressure to the flow process of low pressure area, very fast by be enclosed on slender pipeline with good heat transfer capacity or the capillary materials in the valve pipe, under capillary force or action of gravity, absorbed to the zone of high pressure flowing liquid.2. in the valve vapour-liquid interface far below condensation chamber liquid collecting face height.And reach the heating position.
