Abstract
The utility model relates to an anti-drainage automatic exhaust valve for water heating of a heating system. The utility model comprises a valve body, a manual exhaust valve, and a connecting pipe, wherein, the inner part of a working chamber of the valve body is provided with a floating body with a sealing block; the upper part of the valve body is provided with an exhaust passage; the manual exhaust valve is arranged on an exhaust outlet of the exhaust passage; the eccentric passage of the connecting pipe which is arranged at the side lower part of the valve body is communicated with the lower part of the working chamber. The utility model is arranged on a radiator. When the utility model is operated, the manual exhaust valve lies in a normally open state, the hot water causes the floating body to be floated up to block the inlet of the exhaust passage, and the hot water is prevented from exhausting. The utility model has the advantages of reasonable structure, and convenient operation.
Description
The utility model belongs to the anti-draining automatic exhaust steam valve of heating system annex air bleeding valve, particularly hot-water heating.
At present, the air bleeding valve of installing on radiator is a manual exhaust valve, when needing the steam in row's radiator, can realize manual exhaust with the thimble that hand is twisted on the air bleeding valve, but, also can emit hot water in the radiator by manual exhaust valve, the hot water in the heating system runs off, and can influence the normal operation of heating system.
The purpose of this utility model is to provide a kind of hot-water heating to prevent the draining automatic exhaust steam valve, not only can discharge the steam that collection is deposited in the radiator automatically, but also can prevent that the hot water in the radiator from discharging from air bleeding valve.
The utility model is achieved in that hot-water heating prevents the draining automatic exhaust steam valve, comprise valve body, manual exhaust valve and adapter, the buoyancy aid that has sealing block is installed in the operating room of valve body, the inwall of buoyancy aid external diameter and operating room is a matched in clearance, be provided with the exhaust passage on valve body top, the center of sealing block is corresponding on the center of the air inlet of exhaust passage and the buoyancy aid, on the exhaust outlet of exhaust passage manual exhaust valve is installed, communicates with the bottom of operating room in the eccentric channel of the adapter of the side lower part of valve body.
The utility model is installed in the upper lateral part of radiator by adapter, during work, manual exhaust valve often is in opens, the steam in the radiator enters the operating room by the eccentric channel of taking over, and steam is by the gap between buoyancy aid and the chamber wall, discharge through air bleeding valve from the exhaust passage, the proportion of buoyancy aid, floats buoyancy aid when hot water enters the bottom, operating room less than hot water greater than steam, sealing block on the buoyancy aid is adjacent to the air inlet of exhaust passage, has stoped the discharge of hot water.
Accompanying drawing is a structural representation of the present utility model, below in conjunction with accompanying drawing the utility model is further described, the anti-draining automatic exhaust steam valve of hot-water heating comprises valve body (1), manual exhaust valve body (11) and adapter (6), the buoyancy aid (5) that has sealing block (4) is installed in the operating room (3) of valve body (1), the external diameter of buoyancy aid (5) is a matched in clearance with the cooperating of inwall of operating room (3), on the inwall of operating room (3), be evenly equipped with guiding rib (9), make the external diameter of buoyancy aid (5) and the inwall of operating room (3) form the gap, be provided with exhaust passage (2) on valve body (1) top, the center of the air inlet of exhaust passage (2) is corresponding with the center that buoyancy aid (5) is gone up sealing block (4), manual exhaust valve (11) is installed on the exhaust outlet of exhaust passage (2), on the horizontal segment of exhaust passage (2), be provided with pit, in pit, be placed with glass garden ball (12), the diameter of garden ball (12) is greater than the diameter of exhaust passage (2), and the sphere of garden ball (12) matches with the sphere of the passway of exhaust passage (2) outlet one side, during use, if the utility model has been adorned on radiator, garden ball (12) is positioned on the exhaust passage (2), the hot water of discharging from radiator dashes garden ball (12) passway of (2) outlet one side to the exhaust passage, garden ball (12) blocks the passway, hot water in the radiator can not be discharged from the utility model, eccentric channel (7) in the adapter (6) of the side lower part of valve body (1) communicates with the bottom of operating room (3), eccentric channel (7) porch is equipped with filter screen (13), to filter the impurity in the heating installation water, the base plane of (3) is provided with uniform brace table (8) in the operating room, make buoyancy aid (5) and bottom, operating room (3) keep certain space, the top plan of (3) is provided with uniform boss (10) in the operating room, and buoyancy aid (5) top seal piece (4) plane exceeds the plane on buoyancy aid (5) top.
