By adopting the scheme, the invention ensures that the air pressure is in the proper range, and additionally can control the water level in the shell to be in a certain range so as to avoid the loss of the steam during the drainage of the water.
Description
Technical field
The present invention relates to a kind of heating equipment, and particularly a kind of steam heating is from controlling drainage.
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 than the temperature height 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 is subjected to 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, the content of water reaches certain proportion in the steam heating system, just water need be drained, at this purpose, adopt draining valve at pipe end in the prior art, after but draining valve is opened, water and steam in the heating system are drained simultaneously, have brought the loss of quantity of steam, can't reach a purpose of not exhaust of draining.Chinese patent ZL200920101370.9 belongs to a kind of self-draining arrangement, but this device needs manually regularly water is drained, and automation is not high.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of steam heating from controlling drainage, it can control the storage of water, and avoids the loss of steam when draining.
For solving the problems of the technologies described above, steam heating of the present invention comprises housing from controlling drainage, housing top is communicated with air inlet pipe, this air inlet pipe is provided with the control air parcel, this control air parcel is a hollow cavity, air inlet pipe is passed the cavity of control air parcel, and control air parcel inside is provided with current limiting plate, and this current limiting plate is provided with an above metering hole, described housing top is communicated with observation panel, this observation panel is provided with air bleeding valve, and described housing bottom is communicated with drainpipe, and it is cursory that described enclosure interior is provided with, described cursory bottom is provided with connecting rod, this connecting rod bottom is connected with the water shutoff ball, and described lower housing portion is fixed with fixed mount, and described connecting rod passes the middle part of fixed mount.
Described air inlet pipe also is communicated with the slagging-off pipe, and the end of this slagging-off pipe is provided with the slagging-off valve.
The quantity of described metering hole is 2 and is distribution up and down.
Describedly elastic positioning card is installed on cursory, this locator card contacts with inner walls.
After adopting such scheme,, therefore can guarantee that air pressure is in suitable scope owing to be provided with metering hole, in addition because switch cursory, water shutoff ball control drainpipe, the water level that it can be controlled in the housing is in certain scope, and avoids the loss of steam when draining, a large amount of saving steam.
This structure fabrication cost is lower in addition.
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Fig. 1 is the structural representation of steam heating of the present invention from controlling drainage.
Fig. 2 is the enlarged diagram of steam heating shown in Figure 1 from controlling drainage A place.
The specific embodiment
As Fig. 1, shown in Figure 2, steam heating of the present invention comprises housing 3 from controlling drainage, housing 3 tops are communicated with air inlet pipe 15, this air inlet pipe 15 is provided with control air parcel 14, this control air parcel 14 is a hollow cavity, air inlet pipe 15 is passed the cavity of control air parcel 14, control air parcel 14 inside are provided with current limiting plate 13, this current limiting plate 13 is provided with an above metering hole 12, described housing 3 tops are communicated with observation panel 2, this observation panel 2 is provided with air bleeding valve 1, and described housing 3 bottoms are communicated with drainpipe 9, and described housing 3 inside are provided with cursory 5, described cursory 5 bottoms are provided with connecting rod 6, these connecting rod 6 bottoms are connected with water shutoff ball 8, and described housing 3 bottoms are fixed with fixed mount 7, and described connecting rod 6 passes the middle part of fixed mount 7.
The diameter of water shutoff ball 8 is a bit larger tham the internal diameter of drainpipe 9, and connecting rod 6 is in vertical position and coaxial with drainpipe 9.
Described air inlet pipe 14 also is communicated with slagging-off pipe 11, and the end of this slagging-off pipe 11 is provided with slagging-off valve 10.Slagging-off valve 10 can be drained some impurity in advance.
The quantity of described metering hole 12 is 2 and is distribution up and down.Metering hole 12 is set limits gas flow with the size of metering hole 12, and then limit the pressure of gas in the passage of back, two metering holes 12 that distribute up and down are set prevent to have blocked entering of gas when water flows through metering hole 12.
On described cursory 5 elastic positioning card 4 is installed, this locator card 4 contacts with housing 3 inwalls.Elastic positioning card 4, cursory 5 widthwise size are slightly littler than housing 3, elastic positioning card 4 can prevent cursory 5 take place lateral shifts or with housing 3 collision frictions.
Cursory height can be adjusted as the case may be, and generally speaking, cursory suffered buoyancy should be greater than the resistance of housing 3 internal gas pressures generation.
The setting of fixed mount 7 is to cause water shutoff ball 8 and drainpipe 9 dislocation in order to place the connecting rod teeter.
During use, steam and water enter housing 3 from air inlet pipe 15 through slagging-off pipe 11, control air parcel 14, and wherein water accumulates in housing 3 bottoms, and hold up cursory 5, when cursory 5 rose to certain altitude together along with the water surface, the water shutoff ball 8 on cursory 5 tractive drainpipes 9 tops rose, and leave drainpipe 9, at this moment, drainpipe 9 is open-minded, and water is discharged from drainpipe 9, when water level descends, cursory 5 descend, and water shutoff ball 8 is closed drainpipe 9 by the top inlet that the gravity effect descends and also drops on drainpipe 9 again.
This structure can be provided with miniature air bleeding valve after connecting into the heating path with other heating installation on each monomer heating installation, can discharge to guarantee the cold air of retaining.A small amount of gas of getting rid of can guarantee the humidity of room air.
