Description
Technical field
The present invention relates to valve and manufacture field, particularly a kind of outer silk Filter valve.
Background technique
Floor heating is the abbreviation of floor panel heating, English is Radiant Floor Heating, to take whole ground as radiator, by the heating agent in flooring radiation layer, the whole ground of homogeneous heating, utilize the make progress rule of radiation of the accumulation of heat on ground self and heat to conduct from the bottom to top, reach the object of heating.Water floor heating refers to water is heated to uniform temperature, is transported to underfloor water pipe pipe radiating network, by floor, is generated heat and is realized a kind of heating mode of heating object.
The temperature gradient that low-temperature ground heating agent successively decreases to head gradually at indoor formation sole, thus give the warm cool comfortable feel of pin.Ground radiation heating meets the fitness theory of the traditional Chinese medical science " temperature foot top is cool ", is the heating system of current the most comfortable, is also the symbol of modern life quality.
From thermal medium, be divided into water and warm up the large class of electric floor heating two, from paving structure, be divided into wet type and warm up two kinds of dry floor heatings, dry floor heating does not need peastone backfill (belonging to ultrathin); From surperficial decoration materials, be divided into floor type and warm up the floor heating of floor tile type; From function, be divided into common the far-infrared ground heating that warms up.
Water floor heating is that Terrestrial is that to take temperature be not heating agent higher than the hot water of 60 ℃, in heating pipe, circulate, heating floor, by ground with the heat transfer type of radiation (mainly) and convection current (less important) heating system to indoor heating.
In the circulatory system in the heating pipe of water floor heating, at present, conventionally adopt various valves to carry out the hot water circuit of different piece in control room.The general valve of the many employings of existing valve, this is almost the universal solution of current floor heating industry.But find according to the investigation to actual behaviour in service, in actual using process, because the long-term variation that colds and heat succeed each other need to be stood in the heating pipe inside of floor heating, and because causing overpressure, cold and hot variation changes greatly, easily cause inner-walls of duct, there is malformation in valve place particularly, causes the anti-fatigue performance of pipe racks to decline, and finally causes breaking.Although delivering hot water's pipeline can adopt plastic tube, so that offset cold and hot expansion for the impact of pipeline, valve, due to its sealing requirements, conventionally remains and adopts metal quality, and these metal member mades easily corrode, and cause equipment Rapid Damage.
For the problems referred to above, what the solution having related in prior art adopted conventionally is the pipe thickness that improves pipeline, to arrive the structural strength that improves pipeline, improve the object of the actual life of pipeline, otherwise, also cause existing valve tube wall thickness to increase, the metal use amount while manufacturing valve increases, and has directly improved manufacture cost.Secondly, also cause the body of valve to seem very thick, have influence in the process of decoration and can well valve be carried out to hiding problem.Therefore, be necessary to develop and a kind ofly have on the basis of thinner pipe thickness, can keep the valve pipe structure of the structural strength of existing pipeline.
