Provided by the utility model is the anti-freeze type Automatic steam trap Trap of falling the hanging bucket type of band honeycomb duct, mainly by valve body, valve gap, valve seat, spool, connecting rod, hex head bolt, hang upside down bucket, honeycomb duct, filter screen, filter screen plug, the valve pocket bolt that discharges water and form, closely be connected by hex head bolt between valve gap and the valve body, form the opening/closing system of Automatic steam trap Trap jointly by hanging upside down bucket, connecting rod, spool, valve seat.
The technological scheme that its technical problem that solves the utility model adopts mainly contains 2 points:
1, at the valve inner of original Automatic steam trap Trap of falling the hanging bucket type; steam honeycomb duct of design casting; at operating pressure differential under the very low or condensing capacity situation seldom; can make barrel opening that hangs upside down of Automatic steam trap Trap valve inner be in the steam isolation all the time; formation water seal protection; prevent that Automatic steam trap Trap from producing leakage vapour, the service behaviour and the working life of improving the novel Automatic steam trap Trap of falling the hanging bucket type.
2, below the valve body front of original Automatic steam trap Trap of falling the hanging bucket type, design and installation has the valve pocket bolt that discharges water, and plays blowdown, two functions that discharge water, and can carry out valve pocket cleaning and water of condensation and discharge, make the novel Automatic steam trap Trap of falling the hanging bucket type possess antifreeze ability, longer service life is of a specified duration.
The beneficial effects of the utility model are, both can be when steam-heating apparatus or steam pipe system stop supplies steam, the water of condensation of accumulating in the Automatic steam trap Trap of falling the hanging bucket type valve pocket is got rid of rapidly, guarantee that this Automatic steam trap Trap can not endure cold, can guarantee at operating pressure differential under the very low or condensing capacity operating conditions seldom again, the Automatic steam trap Trap of falling the hanging bucket type can proper functioning, stops to run the vapour phenomenon, has significantly improved the workmanship and the economic benefit of Automatic steam trap Trap.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the longitudinal profile tectonic maps of the anti-freeze type Automatic steam trap Trap of falling the hanging bucket type of band honeycomb duct.
Fig. 2 is that the discharge water sectional structural map of bolt of valve pocket is installed in valve body front below.
Among the figure: valve body (1), valve gap (2), valve seat (3), spool (4), connecting rod (5), hex head bolt (6) hangs upside down bucket (7), honeycomb duct (8), filter screen (9), filter screen plug (10), the valve pocket bolt (11) that discharges water.
Embodiment
As shown in Figure 1, the anti-freeze type Automatic steam trap Trap of falling the hanging bucket type of honeycomb duct is mainly by valve body (1), valve gap (2), valve seat (3), spool (4), connecting rod (5), hex head bolt (6), hang upside down bucket (7), honeycomb duct (8), filter screen (9), filter screen plug (10), the valve pocket bolt (11) that discharges water is formed.At first, the Automatic steam trap Trap of falling hanging bucket type inside hang upside down bucket (7) because self gravity drives connecting rod (5) and makes spool (4) break away from valve seat (3), Automatic steam trap Trap is in opening state.When steam-heating apparatus or steam pipe system supply steam, mix the filtration of incondensable gas through stainless steel filter screen (9), beginning enters the Automatic steam trap Trap valve pocket along the honeycomb duct (8) of valve inner, mixing an incondensable gas part discharges by the aperture that hangs upside down bucket (7) top, another part passes through along hanging upside down bucket (7) opening below, discharges valve body (1) rapidly through valve seat (3); And then the water of condensation that the pipeline thermal exchange produces enters the Automatic steam trap Trap valve pocket, what valve body (1) was inner hangs upside down bucket (7) by self gravitation, is in the sinking state, and Automatic steam trap Trap valve seat (3) is still opened, water of condensation is owing to the effect of operating pressure differential, by valve seat (3) discharging rapidly; After water of condensation has been arranged, fresh steam directly enters hang upside down barrel (7) of Automatic steam trap Trap along honeycomb duct (8), steam flow progressively increases, hang upside down bucket (7) simultaneously and produce buoyancy upwards, driving connecting rod (5) promotion spool (4) moves up, close valve seat (3), Automatic steam trap Trap quits work; Hang upside down bucket (7) top and have an aperture, energy is emptying gas automatically, when a part of steam is discharged from aperture, when another part steam becomes water of condensation through valve body heat radiation condensation, hang upside down bucket (7) loss of buoyance to sinking, be with connecting rod (5) to open valve seat (3) once more, water of condensation is by pressure reduction discharging again; The condensing capacity that produces when the Automatic steam trap Trap valve pocket is inner more after a little while; when perhaps operating pressure differential is low; fresh steam directly enters the top that hangs upside down bucket (7) through honeycomb duct (8), owing to hang upside down bucket (7) opening the water seal protection is arranged all the time, and steam can not cause leakage.The Automatic steam trap Trap of falling the hanging bucket type utilizes the density difference of water of condensation and steam, by the variation of water of condensation liquid level, make hang upside down the bucket (a 7) take off and landing strip movable valve plug (4) come the opening and closing drain valve, periodic duty, the discontinuity draining reaches the block steam and drain water purpose.
