Description
Technical field
This utility model belongs to air bleeding valve technical field, especially relates to a kind of solar thermal collection system air bleeding valve.
Background technology
Solar thermal collection system uses air bleeding valve to be mainly lever in the market, by the lifting of ball float, drives pin
The piston of formula is opened or closes steam vent.This structure is primarily present three kinds of drawbacks in use process.First, capacity
Little: this type air bleeding valve is all to drive tapered metallic rod block or open venthole, because of by mounting ring by ball float lifting
Decision size in border is all without too big, so designing and arranging pore is smaller is generally less than 5mm.But large-sized solar heat collecting engineering,
Capacity relatively is bigger, especially often occurs aerofluxus not smooth problem summer.By calculating according to conventional 50 vacuum of heat collector
Pipe, collector area 8 squares maximum capacity in summer is not less than 12 cubes/minute, and aerofluxus aperture design should be not less than 10mm.The
Two, easily blocking: because exhaust apparatus design is at the most significant end of pipeline, when solar energy system runs, buoyancy of water can impurity incrustation scale,
Foreign material, plastics etc. float to pipeline top and block on air bleeding valve, cause air bleeding valve blocking to use.3rd, easily get rusty:
Because of high temperature, the high humidity environment of solar energy system, the material of air bleeding valve is required the highest, no matter stainless steel, or copper material,
The most inevitably produce corrosion.Because using the pin hole blockage structure of bevel-type, the highest to the smoothness requirements of sealing surfaces.Row
The anvil cinder that air valve self produces is easy to block steam vent.
In order to improve prior art, people have carried out long-term exploration, it is proposed that various solutions.
Such as, Chinese patent literature discloses a kind of solar thermal collector and air bleeding valve [application number: CN201420276667.X] thereof, bag
Including shell and the air bleeding valve being arranged on shell, this air bleeding valve includes exhaustor and protective cover, outside this exhaustor first end stretches into
The inside of shell, the second end is arranged on the outside of shell and is connected with protective cover；This protective cover is for having internal cavities and one end
The lid of opening, the second end puts in the internal cavities of lid and fixing with lid is connected, this second end end and internal cavities pair
Steam vent should be offered in place.
Although such scheme to some extent solves the deficiencies in the prior art, but the air bleeding valve of solar thermal collector
Capacity the least, be still susceptible to clogging, easily get rusty, the anvil cinder after getting rusty be easy to block steam vent.
Utility model content
