Abstract
The utility model relates to a pressure release valve, specifically relates to the pressure release valve used on drinking water machine, which comprises a valve body, an air passing channel and an air releasing channel are arranged in the valve body, a pressure adjusting mechanism is arranged inside the air releasing channel, the exhaust channel is also arranged inside the valve body, a connected hole is arranged between the exhaust channel and the air passing channel, the exhaust channel is connected with the outside, a seal body is arranged inside the air passing channel, the connected hole is blocked after the rising of the seal body, and the seal body is at the air inlet of the air passing channel when the seal body falls down. The structural design of the utility model is simple and reasonable, the seal body is clashed to rise and block the connected hole when water is put into the inner refill, the remaining pressure is released through the concave groove of the surface of the connected hole when water input is stopped, the seal body falls on the air inlet port of the air passing channel, the pressure inside the inner refill body is consistent to the atmospheric pressure all the time and the chlorine gas can be discharged through the connected hole. The adjusting mechanism works when the pressure on the air passing channel is too large, the air releasing channel can still release pressure when the inner refill is not filled with water.
Description
Technical field
The utility model relates to a kind of Decompression valves, specifically relates to a kind of Decompression valves that is used on the drinking machine.
Background technique
Now the Decompression valves on the drinking machine has only the pressure release function, when having only pressure in the inner lining to reach predetermined pressure, Decompression valves just starts work, and very big pressure is still arranged in the inner lining so all the time, easily inner bag is damaged.And tap water contains chlorine residue, and former energy-saving drinking machine is totally-enclosed, and in the heating process, chlorine residue can't be volatilized, and influences the taste of water.
Summary of the invention
Therefore, the purpose of this utility model is to provide a kind of Decompression valves that can arrange chlorine again can pressure release.
The purpose of this utility model is to realize like this.
A kind of Decompression valves, comprise valve body, be provided with gas passage and disappointing passage in the valve body, be provided with pressure-regulating device in the disappointing passage, also be provided with the exhaust passage in the described valve body, be provided with connecting port between exhaust passage and the mistake gas passage, the exhaust passage communicates with the external world, cross in the gas passage and be provided with seal, shutoff connecting port after seal rises, seal were positioned at gas passage suction port when falling.
Above-mentioned purpose also can be done further perfect by the following technical programs.
Described seal is a spheroid, and its radius is less than crossing the gas channel radius.
Described connecting port surface is provided with a groove that was communicated with gas passage and exhaust passage at least.
The described suction port of gas passage excessively place is provided with the pad of a band through hole, and seal is pressed in gasket surface when falling.
Described pressure-regulating device comprises adjusting nut, sealed door and spring, and adjusting nut is located at the passage external port of losing heart, and the sealed door sealing is communicated with lose heart passage and the gas port of crossing of crossing the gas passage, and spring connects adjusting nut and sealed door.
Be provided with the relief opening that is communicated with between described exhaust passage and the disappointing passage.
The utility model structural design advantages of simple, when inner bag discharges water, seal by water dash rising shutoff connecting port, when stopping to discharge water, groove venting overbottom pressure by the connecting port surface, seal dropped on the air inlet port of gas passage, and the pressure in the inner lining is consistent with atmospheric pressure all the time, and chlorine can also be discharged by connecting port.Served as the gas channel pressure when excessive, pressure-regulating device work, disappointing passage can also pressure release, when inner bag does not discharge water.
