Abstract
The invention discloses an automatic drainage device of a steam warmer. The automatic drainage device comprises a shell, an air inlet pipe and a drain pipe, wherein the upper part of the shell is communicated with the air inlet pipe, the bottom of the shell is communicated with the drain pipe, a buoy is arranged inside the shell, a lever is connected below the buoy, a support is fixedly connected at the upper part of the drain pipe, and a seal cover corresponding to an inlet at the top of the drain pipe is arranged at the lower part of the lever. The structure can control water level in the shell to be in a certain range, avoid steam loss in drainage, thus obviously saving steam.
Description
Technical field
The present invention relates to a kind of heating equipment, particularly a kind of automatic water draining apparatus of steam heater.
Background technology
In recent years, steam heating is still used in the part as some regional specified conditions of the north a kind of heating system down, because steam is higher than the temperature of hot water, heat conductivility is quite a lot of, the pipe diameter of carrying heating agent to use, also than hot-water heating carefully; Particularly after evaporation became condensed water, its volume can reduce greatly, so return pipe is also thinner than steam pipe.This just makes steam heating lower than the initial cost of hot-water heating, and this is an advantage of steam heating.In addition, steam heating is littler than the thermal inertia of hot-water heating, and promptly immersion heater is cool also soon.
On the other hand, a remarkable shortcoming of steam heating is: in the heating process, steam receives low temperature effect can produce big water gaging; And water accumulates in the circulation and the heating effect that can influence steam in the radiator, and the content of water reaches certain proportion in the steam heating system, just need water be drained; To this purpose; Adopt draining valve at pipe end in the prior art, but after draining valve was opened, water and steam in the heating system were drained simultaneously; Bring the loss of quantity of steam, can't reach a purpose of not exhaust of draining.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, a kind of automatic water draining apparatus of steam heater is provided, it can control the storage of water, and when draining, avoids the loss of steam.
For solving the problems of the technologies described above a kind of automatic water draining apparatus of steam heater of the present invention, a kind of automatic water draining apparatus of steam heater; Be provided with housing, air inlet pipe, reach drainpipe, said housing top is communicated with air inlet pipe, and said housing bottom is communicated with drainpipe; It is cursory that said enclosure interior is provided with, and it is characterized in that: said housing top is communicated with observation panel, and this observation panel is provided with air bleeding valve; Said cursory below is connected with lever; This bottom and bearing are hinged, and said bearing is fixed in drainpipe top, and said lever bottom has been provided with and the corresponding capping that enters the mouth of drainpipe top.
Above one section on said drainpipe top be that horizontal direction distributes, said capping area enters the mouth greater than the drainpipe top.
After adopting such scheme, formed one by cursory, lever, capping and overlapped the switch of controlling drainpipe according to water level automatically, the water level that it can be controlled in the housing is in certain scope, and when draining, avoids the loss of steam, has practiced thrift steam significantly.This structure fabrication cost is lower in addition.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is done further detailed explanation.
Fig. 1 is the structural representation of a kind of automatic water draining apparatus of steam heater of the present invention.
Fig. 2 is the enlarged diagram of drainpipe top and capping among Fig. 1.
Fig. 3 is the left view on drainpipe top among Fig. 2.
The specific embodiment
Like Fig. 1, Fig. 2 and shown in Figure 3, a kind of automatic water draining apparatus of steam heater of the present invention is provided with housing 3, air inlet pipe 8, reaches drainpipe 4; Said housing 3 tops are communicated with air inlet pipe 8, and said housing 3 bottoms are communicated with drainpipe 9, and said housing 3 inside are provided with cursory 5; It is characterized in that: said housing 3 tops are communicated with observation panel 2; This observation panel 2 is provided with air bleeding valve 1, and said cursory 5 belows are connected with lever 6, and this bottom and bearing 10 are hinged; Said bearing 10 is fixed in drainpipe 4 tops, and said lever 6 bottoms have been provided with and the inlet 9 corresponding cappings 7 of drainpipe 4 tops.
During use, cursory 5 when low, and lever 6 and capping 7 positions are also lower, and capping 7 this moment is just in time sealed drainpipe 4 tops inlet 9; When steam and water constantly get into housings 3 from air inlet pipe 8, wherein water accumulates in housing 3 bottoms, and will cursory 5 picking-ups, when cursory 5 rise to certain altitude together along with the water surface; Cursory 5 tractive levers 6, thus the capping 7 on the lever 6 is also moved up, make capping 7 separate, at this moment with drainpipe 4 tops inlet 9; Drainpipe 4 water routes are open-minded, and water is discharged from drainpipe 4, when water level descends; Cursory 5 descend, and capping 7 descends again, just drainpipe 4 tops inlet 9 sealings again when reducing to certain position.
