Description
Technical field
The invention belongs to outlet valve field, especially relates to a kind of automatic control pressure vent.
Background technique
The principle that outlet valve adopts is mainly, while having gas overflowing in system, gas can be climb along pipeline, is finally gathered in the peak of system, and outlet valve is generally all arranged on system peak, when gas enters the top that outlet valve valve pocket is gathered in outlet valve, along with increasing of gas in valve, pressure rise, when gas pressure is greater than system pressure, gas can make the water surface in chamber decline, and floating drum declines with water level, opens relief opening; After gas drains, water level rises, and floating drum also rises thereupon, closes relief opening.Same reason produces negative pressure in system, and in valve pocket, the water surface declines, and Exhaust Open, because now external atmosphere pressure force rate system pressure is large, so atmosphere can enter system by relief opening, prevents the harm of negative pressure.
But the floating drum of common outlet valve is in ascending and descending process, because the circulation up and down of gas has some setbacks, easy jam; And the elastic components such as spring that exhaust ports is used also easily damage, and cause the malfunctioning of outlet valve.
Summary of the invention
What the invention will solve is the common jam of outlet valve and the flimsy problem of appearance.
For solving the problems of the technologies described above, the technological scheme that the invention adopts is: a kind of automatic control pressure vent, comprise housing, floating drum and seal valve, described housing is provided with the water intake of below and the relief opening of top, described floating drum and seal valve are positioned at described enclosure interior, the top of described floating drum is connected with the bottom of described seal valve by lever, described seal valve can stop up described exhaust port, described seal valve comprises sealed support, jump ring, jump ring support and with the seal valve seat of central through bore, the lower end of described sealed support is connected with lever, its upper end is flexibly connected with described seal valve seat, and described sealed support can seal from lower end the central through bore of described seal valve seat by sealing gasket, the upper end of described seal valve seat gets lodged in described exhaust port, described jump ring support casing is contained on described seal valve seat, its both sides are connected with the two ends of jump ring respectively, the middle part of described jump ring is socketed on the stage casing of described sealed support.
Preferably, described jump ring is arc type structure, and in the middle of its arc type structure second be curved to be socketed in the groove in stage casing of described sealed support.
Preferably, the upper end of described sealed support is provided with a pit, is convenient to place the sealing gasket of the central through bore that seals described seal valve seat.
Preferably, the stage casing of described seal valve seat outer surface is with projection, and its lower end is truncated cone shape structure.
Preferably, on the sidewall of two ends up and down of described floating drum, with annular projection, form the thick dumbbell shape structure in middle thin two ends, the annular projection band at two ends is jagged, and the upper and lower gas of described floating drum can be circulated.
Preferably, the bottom of described floating drum is provided with some small embossments.
Preferably, the inwall of described housing is provided with limited step, is less than the size of described floating drum in the enclosure interior size at this step place, to limit the lifting height of described floating drum.
Preferably, the both sides of described jump ring support are respectively with projection or mounting hole, and the two ends of described jump ring are connected with described projection or mounting hole respectively.
Advantage and good effect that the invention has are: this programme has adopted jump ring as elastic component, to produce the restoring force of sealing, under sealing state, can realize O means of press seals, greatly extend the life-span of jump ring, reduce costs, and the new design of floating drum also can make the lifting of its easy on and off, is difficult for jam.

Embodiment
Below in conjunction with the accompanying drawing in the invention embodiment, the technological scheme in the invention embodiment is clearly and completely described, obviously, described embodiment is only the invention part embodiment, rather than whole embodiments.Embodiment based in the invention, those of ordinary skills are not making the every other embodiment who obtains under creative work prerequisite, all belong to the scope of the invention protection.
A lot of details have been set forth in the following description so that fully understand the invention, but the invention can also adopt other to be different from alternate manner described here and implement, those skilled in the art can do similar popularization under the condition without prejudice to the invention intension, so the invention is not subject to the restriction of following public specific embodiment.
Secondly; the invention is described in detail in conjunction with schematic diagram; when the invention embodiment is described in detail in detail; for ease of explanation; the sectional drawing of indication device part structure can be disobeyed general ratio and be done local amplification; and described schematic diagram is example, it should not limit the scope of the invention protection at this.The three-dimensional space that should comprise in addition, length, width and height in actual fabrication.
As shown in Figures 1 to 6, the invention comprises housing 1, floating drum 2 and seal valve, described housing 1 is provided with the water intake of below and the relief opening of top, described floating drum 2 and seal valve are positioned at described housing 1 inside, the top of described floating drum 2 is connected with the bottom of described seal valve by lever, described seal valve can stop up described exhaust port, described seal valve comprises sealed support 3, the jump ring 4 of arc type structure, jump ring support 5 and with the seal valve seat 6 of central through bore, the lower end of described sealed support 3 is connected with lever, its upper end is flexibly connected with described seal valve seat 6, and described sealed support 3 can seal from lower end the central through bore of described seal valve seat 6 by sealing gasket, the upper end of described seal valve seat 6 gets lodged in described exhaust port, described jump ring support 5 is sleeved on described seal valve seat 6, being connected with the two ends of jump ring 4 respectively of described jump ring support 5 both sides mounting holes, the middle part of described jump ring 4 is socketed in the groove in stage casing of described sealed support 3.
The upper end of described sealed support 3 is provided with a pit, is convenient to place the sealing gasket of the central through bore that seals described seal valve seat 6, and the stage casing of described seal valve seat 6 outer surfaces is with projection, its lower end is truncated cone shape structure, when sealing, the bottom surface of round platform contacts with sealing gasket, can realize sealing.
On the sidewall of two ends up and down of described floating drum 2, with annular projection, form the thick dumbbell shape structure in middle thin two ends, the annular projection band at two ends is jagged, and the upper and lower gas of described floating drum 2 can be circulated, and also has leading role, is difficult for jam.
