Abstract
The utility model relates to an automatic exhaust valve of anti-feedback gas for the hot gas heating, which is composed of a valve body float, a water resisting rubber plug, a fastening screw, a sealing ring, a cushion ring, a gas guiding door, a gas exhausting door, a rubber pad of anti-feedback gas, a pressing cover of the rubber pad of anti-feedback gas, a gas exhaust valve cover, etc. The automatic exhaust valve of anti-feedback gas for the hot gas heating can solve the problems of water leakage, dripping, overflowing and the running of the hot water heating system and can prevent the back flowing of the air and control the illegal heating water use. The utility model has the advantages of energy saving, simple structure, heat guaranty, no perishable parts, safety, etc.
Description
The utility model belongs to a kind of anti feedback hot water automatic control pressure vent that heating is used.
The outlet valve that current hot water heating is used has two types, and a kind of is manually to open exhaust, and another kind is an automatic control pressure vent; This outlet valve of two types runs in actual use, emits, water leakage phenomenon is very serious, becomes a big common fault of building industry, is big problem extremely to be solved.
The purpose of this utility model is to provide a kind of air that can prevent to blow back into the hot water automatic control pressure vent in the pipe-line system.Owing to system's seepage and indivedual resident families water, owing to used anti feedback formula hot water automatic control pressure vent, air can't enter water heating system at system's peak after termination of pumping, produces vacuum, arrives to a certain degree then system's no seepage and no leakage, can save softened water, hot water.Circulation time is mended low amounts of water once more.System is horse back full water (do not need the removal system air, both made in the additional water and contained air, also can drain at once) then.The vent plug phenomenon can not take place, hot soon.Avoid because of long circulation head end heat, resident family windows; But end has not been arranged because of air, and both using electricity wisely, fuel saving again take place the phenomenon that heating installation is not warm.
The purpose of this utility model is finished like this: on the top of exhaust valve one circular groove is arranged, an exhaust port is arranged and be interlinked to the outside on circular groove is axial, 6～8 millimeters of exhaust hole depths, there is a gas-tight refluence rubber cushion this external exhaust valve top and prevents the gland (used when needing maintenance to lose efficacy) that water flows out, connect with exhaust valve with exhaust valve cap, there is a through hole on the exhaust valve top, and through hole and gas-tight refluence rubber cushion gland convex match.
The anti feedback hot water automatic control pressure vent that the utility model proposes is owing to realized said structure, so it has demonstrated following advantage than existing outlet valve:
1. manufacturing process is simple, the novel structure uniqueness, and volume is little in light weight, and no easily damaged parts is not fragile.
2. the exhaust port sectional area is big, and exhaust velocity is fast.
3. can prevent that air from flowing backwards, saving softened water, fuel etc.
The anti feedback automatic vent valve arrangement that the utility model provides is provided by following drawings and Examples.
Accompanying drawing 1 is the utility model overall structure sectional view;
Accompanying drawing 2 is plan views of model utility anti feedback part.
Mark block water plug, (13) float, (14) valve body, (15) air guide port, (16) seal ring, (17) sealing gasket of (1) screw, (2) valve gap, (3) exhaust valve cap, (4) gas-tight refluence rubber cushion gland, (5) gas-tight refluence rubber cushion, (6) circular groove, (7) exhaust port, (8) exhaust valve, (9) packing ring, (10) tightening nut, (11) nut, (12) wherein in the accompanying drawing.
Describe a embodiment with reference to the accompanying drawings in detail according to the anti feedback hot water automatic control pressure vent that the utility model proposes.
The anti feedback hot water automatic control pressure vent that the utility model is provided is installed in the peak of heating system, this valve will vertically be installed, transverse tube should have certain slope, metope is avoided in the position of exhaust port (7), with loosening 2～3 buttons (being rotated counterclockwise) of exhaust valve cap (3), as air when system pipeline is raised to this valve, be pooled to valve body top air will from air guide port (15) upwards below gas-tight refluence rubber cushion (5) to circular groove (6), from exhaust port (7) air is drained; After air is got rid of, the valve body (14) that rises to waterborne of system pipeline, water floats float (13).The plug (12) that blocks water is combined closely with air guide port (15), and water can not be discharged from air guide port.When not working as heating system, or because of various reasons, the interior water level of valve body (14) is fallen, float (13) falls, air guide port (15) breaks away from the plug (12) that blocks water, because the gravity of anti-aqueous reflux rubber cushion gland (4) forces gas-tight refluence rubber cushion (5) that ambient air can't be arrived in the valve body (14).Promptly play automatic vent, work again to prevent that air from flowing backwards.
Claims (4)
1, a kind of anti feedback hot water automatic control pressure vent, form by valve body (14), float (13), the plug that blocks water (12), tightening nut (10), seal ring (16), packing ring (9), sealing gasket (17), valve gap (2), screw (1), nut (11) air guide port (15), exhaust valve (8) etc., it is characterized in that there are a gas-tight refluence rubber cushion (5), gas-tight refluence rubber cushion gland (4) and exhaust valve cap (3) in exhaust valve (8) top.
2, anti feedback hot water automatic control pressure vent according to claim 1, it is characterized in that there is a circular groove (6) on exhaust valve (8) top, have on axially an exhaust port (7), exhaust port (7) radially to have a through hole to communicate on the top for dark 6～8 millimeters with exhaust port (7) along circular groove (6).
3, anti feedback hot water automatic control pressure vent according to claim 1 is characterized in that gas-tight refluence rubber cushion gland (4) is convex.
4, anti feedback hot water automatic control pressure vent according to claim 1 is characterized in that exhaust valve cap (3) upper end has a through hole, aperture and gas-tight refluence rubber cushion gland (4) convex to match.
