Abstract

The utility model discloses an automatic exhaust valve. The automatic exhaust valve comprises a valve body (1), a floating ball (2) arranged in the valve body (1) and an exhaust valve plug (3) arranged at the upper end of the floating ball (2). The overall floating ball (2) is of a big-end-down circular truncated cone shape. The upper end and the lower end of the exhaust valve plug (3) are provided with a protrusion (4) and an annular groove (5) respectively. An exhaust valve guide pipe (6) is arranged above the exhaust valve plug (3). The protrusion (4) extends into the exhaust valve guide pipe (6). A nut (7) is arranged above the exhaust valve guide pipe (6). The side face of the nut (7) is provided with an exhaust hole (8). A plugging pad (9) is arranged at the upper end of the nut (7). An O-shaped gasket (10) is arranged at the bottom end of the protrusion (4). The automatic exhaust valve is good in sealing performance, long in service life, reasonable in structural design and high in practicability.

Description

A kind of automatic control pressure vent
Technical field
The utility model relates to heat radiator fitting field, is specifically related to a kind of automatic control pressure vent.
Background technique
Automatic control pressure vent is a kind of heating system peak that is installed on, be used for discharging the valve that produces gas in heating system, automatic control pressure vent in the market, of a great variety, different, but be all to utilize buoyancy to promote ball float move to realize automatic unlatching or close mostly, problem of ubiquity, current outlet valve seal is poor, and serious wear works long hours, drain tap plug easily comes off on buoyancy aid, as part exchanging not in time, can affect heat supply.Working life popular on real existing market is short, sealing is poor, and structural design is unreasonable, can not satisfy the demands of consumers.
Model utility content
(1) technical problem that will solve
The technical problems to be solved in the utility model is to provide good airproof performance, long service life, and reasonable in design, has the automatic control pressure vent of practicability.
(2) technological scheme
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of automatic control pressure vent, comprise valve body (1), be located at the ball float (2) in described valve body (1) and the drain tap plug (3) that is located at described ball float (2) upper end, described ball float (2) integral body is little round table-like of Di great Ding, described drain tap plug (3) top and bottom are respectively equipped with projection (4) and annular groove (5), the top of described drain tap plug (3) is provided with exhaust valve guide (6), described projection (4) stretches in described exhaust valve guide (6), the top of described exhaust valve guide (6) is provided with nut (7), the side of described nut (7) is provided with exhaust port (8), the upper end of described nut (8) is provided with shutoff pad (9), the bottom of described projection (4) is provided with O type pad (10).
The below of described ball float (2) and be provided with guide plate (11) in described valve body (1).
The surface of contact of described drain tap plug (3) and exhaust valve guide (6) is same slope and mutually coincide.
Described drain tap plug (3) is injected into one by described annular groove (5) and described ball float (2), and described ball float (2) is solid construction.
(3) beneficial effect
The utility model is compared to prior art, there is following beneficial effect: because drain tap plug top and bottom are respectively equipped with projection and annular groove, projection stretches in exhaust valve guide, the upper end of nut is provided with shutoff pad, the bottom of projection is provided with O type pad, the sealing that is conducive to improve automatic control pressure vent, increases the service life; Owing to being provided with guide plate in valve body, being conducive to the flow direction of water in control valve body, thereby improving the working efficiency of automatic control pressure vent; Because ball float integral body is little round table-like of Di great Ding, be conducive to improve the buoyancy of ball float, thereby improve the sensitivity of automatic control pressure vent.The utility model good airproof performance, long service life, reasonable in design, has practicability.
Accompanying drawing explanation
Fig. 1 is the structural drawing of automatic control pressure vent of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, a kind of automatic control pressure vent, comprise valve body 1, the drain tap plug 3 that is located at the ball float 2 in described valve body 1 and is located at described ball float 2 upper ends, described ball float 2 integral body are little round table-like of Di great Ding, described drain tap plug 3 top and bottom are respectively equipped with projection 4 and annular groove 5, the top of described drain tap plug 3 is provided with exhaust valve guide 6, described protruding 4 stretch in described exhaust valve guide 6, the top of described exhaust valve guide 6 is provided with nut 7, the side of described nut 7 is provided with exhaust port 8, the upper end of described nut 8 is provided with shutoff pad 9, described protruding 4 bottom is provided with O type pad 10.
The below of described ball float 2 and be provided with guide plate 11 in described valve body 1.
The surface of contact of described drain tap plug 3 and exhaust valve guide 6 is same slope and mutually coincide.
Described drain tap plug 3 is by described annular groove 5) be injected into one with described ball float 2, described ball float 2 is solid construction.
The utility model is because drain tap plug top and bottom are respectively equipped with projection and annular groove, projection stretches in exhaust valve guide, and the upper end of nut is provided with shutoff pad, and the bottom of projection is provided with O type pad, be conducive to improve the sealing of automatic control pressure vent, life-span time expand; Owing to being provided with guide plate in valve body, being conducive to the flow direction of water in control valve body, thereby improving the working efficiency of automatic control pressure vent; Because ball float integral body is little round table-like of Di great Ding, be conducive to improve the buoyancy of ball float, thereby improve the sensitivity of automatic control pressure vent.The utility model good airproof performance, long service life, reasonable in design, has practicability.
Certainly, above is only concrete exemplary applications of the present utility model, and protection domain of the present utility model is not constituted any limitation.In addition to the implementation, the utility model can also have other mode of execution.All employings are equal to the technological scheme of replacement or equivalent transformation formation, within all dropping on the utility model scope required for protection.
