Abstract
The utility model relates to an automatic air discharge valve for a radiator. The utility model is composed of an outer housing 1, an air inlet hole 2, a float 3, a drain hole 4, a crank 5, a piston 6, a hinged supporting base 7, a discharge hole 8, a safety valve 9, nuts 10, an air valve 11, etc. When air in the radiator is more, the air can be discharged by the utility model. After the air is discharged, water enters, the float is floated, the air valve is closed, and the water can not be discharged. Therefore, the utility model overcomes the defects that a manual discharge valve is operated by a person, and softened hot water is easy to steal.
Description
The utility model is a kind of water heating device, promptly a kind of water heater automatic control pressure vent.
At present, on every group of water heater, all be provided with manual exhaust valve, turn on outlet valve, can emit the gas in the warmer, make water be full of the warmer space, shut outlet valve again, thereby guarantee the water normal circulation in the warmer.Though manual exhaust valve has above-mentioned effect, also exist many shortcomings, for example, heating system for many groups warmer constitutes often is distributed in how tame user, when certain user wherein nobody the time, exhaust can't be carried out, and can influence the heat supply with the warmer of its polyphone like this.In addition, also some user can not abide by rules and regulations, and utilizes manual exhaust valve to emit hot water often, and for the usefulness of daily lifes such as bathing, because the water portion in the warmer is treated soft water, user cost is very high, thereby causes waste, and influences normal heat supply.
The purpose of this utility model is a kind of being fixed on the warmer of development, can automatic vent, and automatic control pressure vent that but can not draining.
Above-mentioned purpose is realized by following technological scheme: this automatic control pressure vent has a shell that can engage in warmer, enter an end of warmer at shell, if inlet hole, end in the warmer outside, be provided with exhaust port, in housings, be provided with a proportion less than water but, on float, be connected with a crank, between crank and the shell greater than the float of gas, there is hank chord seat to link to each other, there is a valve that communicates with exhaust port the other end top of crank, and a piston is arranged in the valve, and crank and piston join, crank is under the drive of float, by the switch of piston control valve.
In the outlet valve inboard, a side that promptly enters warmer also is provided with spilled water hole.
In the outlet valve outside, also be provided with a safety valve.
The automatic control pressure vent that adopts such scheme to make can be installed in the last angle of warmer, when in the warmer air being arranged, above air concentrates on, enters outlet valve, and passes through valve, discharges from exhaust port.After air was discharged, water entered outlet valve, and float drives crank and piston stroking upward promptly by levitating, closes valve, and water can not be discharged.Thereby overcome the shortcoming of existing manual exhaust valve.
Introduce two kinds of embodiments below in conjunction with accompanying drawing.
Fig. 1 is the main pseudosection of present embodiment.
Fig. 2 is the scheme of installation of present embodiment.
As shown in the figure, this outlet valve is made up of shell 1, inlet hole 2, float 3, spilled water hole 4, crank 5, piston 6, strand chord seat 7, exhaust port 8, safety valve 9, shellfish nut 10, valve 11 etc.Be installed on the last angle of heating installation.When the warmer air more for a long time, air collects in warmer top, enters in the valve from inlet hole 2 or spilled water hole 4 because the proportion of float is greater than air specific weight, can not float this moment, valve is opening state, air can be discharged through valve 11 people's exhaust ports.After air was discharged, water can enter valve, and float 3 is by levitating, drove crank 5, piston 6 is up, and valve 11 is closed, and water can not be discharged.When warmer aerogenesis once more, when drawdown was following to valve body, the water in the valve can release from spilled water hole 4, begins exhaust process again.On shell, can be provided with screw thread, so that the threads engaged on the warmer is installed, the shellfish nut 10 among the figure can play the effect of strengthening connection and sealing when mounted.When preventing that safety valve is malfunctioning, water is gone out from exhaust port 8, is provided with safety valve 9 on top, turns 9 and gas exhaust piping can be forced blocking-up.This shows that this valve need not be hand-manipulated, can work automatically fully, and can only exit, can not discharge water, thereby reach automatic work, the purpose that restriction discharges water.
Second kind of embodiment.Remove the crank of float, and directly connect piston by float, piston enters valve, and when float floated, piston was closed valve, when float falls, and valve opening and exhaust, its working principle is identical with last embodiment.
Claims (3)
1, a kind of warmer automatic control pressure vent, it is characterized in that: this automatic control pressure vent has a shell (1) that can engage in warmer, enter an end of warmer at shell (1), be provided with inlet hole (2), end in the warmer outside, be provided with exhaust port (8), in shell (1) the inside, be provided with a proportion less than water but greater than the float (3) of gas, on float (3), be connected with a crank (5), between crank and the shell, have hank chord seat (7) to link to each other, there is a door gas (11) that communicates with exhaust port (8) the other end top of crank, a piston (6) is arranged in the valve, crank and piston (6) join, and crank (5) can be under the drive of float (3), by the switch of piston (6) control valve (11).
2, warmer automatic control pressure vent according to claim 1 is characterized in that: enter warmer one side at automatic control pressure vent, also be provided with spilled water hole (4).
