Description
Technical field
The invention belongs to valve field, especially relates to a kind of vacuum breaker with degassing function.
Background technique
General vacuum breaker is in closed condition at manifold pressure higher than during barometric pressure, and gas in pipelines effectively can not be got rid of and affect water application efficiency, even endangers pipe safety; Conventional automatic control pressure vent is when normal water supply, the minimum gas that in purging line, medium is separated out can be continued, therefore the diameter of outlet of automatic control pressure vent is less, its air displacement and air compensation are relatively little, when water supply is abnormal, when there is negative pressure in pipeline, simple automatic control pressure vent can not fill into a large amount of gas fast and eliminate rapidly vacuum in pipe, prevents siphon backflow or booster.This just needs a kind of multi-functional structure, can continue to discharge the gas of separating out from water under normal water supply state, can fill into air rapidly again, avoid the siphon backflow under vacuum state and booster when vacuum appears in pipeline.
Summary of the invention
The problem that the invention will solve is to provide a kind of minimum gas that can continue in discharge conduit and can eliminates again vacuum in pipe fast, prevent the device of siphon backflow or booster.
For solving the problems of the technologies described above, the technological scheme that the invention adopts is: a kind of vacuum breaker with degassing function, comprise automatic control pressure vent, also comprise vacuum breakdown device of vacuum, the valve inner cavity of described automatic control pressure vent is provided with inlet hole, described vacuum breakdown device of vacuum is arranged on described inlet hole, described vacuum breakdown device of vacuum comprises valve seat, valve rod and valve plate, described valve seat is fixed on the hole wall of described inlet hole, the center hole of described valve seat is passed in one end of described valve rod, the other end is connected with described valve plate, described valve plate can seal described inlet hole, described inlet hole is opening down and/or also comprise the reply structure controlling valve plate.
Preferably, described valve plate is provided with sealing gasket near the outer side surface of described inlet hole.
Preferably, described reply structure is be sleeved on the spring on described valve rod, and described spring one end is connected with described valve seat, and the other end is connected with described valve plate.
Preferably, described reply structure is compressing tablet, and described compressing tablet one end is fixed on valve interior wall, and the other end is connected with the inner side of described valve plate.
The advantage that the invention has and good effect are: the technical program, the air of separating out from water is got rid of sustainably when pipeline normal water supply, improve water application efficiency, when there is negative pressure in pipeline, vacuum destroying mechanism action integrated in valve, sucks large quantity of air fast, to eliminate vacuum in pipe, prevent siphon from refluxing, this programme has the function of automatic control pressure vent and vacuum breaker valve concurrently, belongs to multi-purpose valve product.

Embodiment
Below in conjunction with the accompanying drawing in the invention embodiment, be clearly and completely described the technological scheme in the invention embodiment, obviously, described embodiment is only the invention part embodiment, instead of whole embodiments.Based on the embodiment in the invention, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the invention protection.
Set forth a lot of detail 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 to implement, those skilled in the art can when doing similar popularization without prejudice to when the invention intension, and therefore the invention is by the restriction of following public specific embodiment.
Secondly; the invention is described in detail in conjunction with schematic diagram; when describing the invention embodiment in detail; for ease of explanation; the sectional drawing of indication device part structure can be disobeyed general ratio and be made partial enlargement; and described schematic diagram is example, it should not limit the scope of the invention protection at this.In addition, the three-dimensional space of length, width and height should be comprised in actual fabrication.
As depicted in figs. 1 and 2, the invention comprises automatic control pressure vent 1, also comprise vacuum breakdown device of vacuum 2, the valve inner cavity of described automatic control pressure vent 1 is provided with inlet hole, described vacuum breakdown device of vacuum 2 is arranged on described inlet hole, described vacuum breakdown device of vacuum 2 comprises valve seat 21, valve rod 22 and valve plate 23, described valve seat 21 is fixed on the hole wall of described inlet hole, the center hole of described valve seat 21 is passed in one end of described valve rod 22, the other end is connected with described valve plate 23, described valve plate 23 can seal described inlet hole, described valve plate 23 is provided with sealing gasket near the outer side surface of described inlet hole.
Described inlet hole is opening down, and when valve plate 23 departs from inlet hole, Action of Gravity Field can make valve plate 23 have a downward restoring force;
Or comprise the reply structure controlling valve plate.Described reply structure is be sleeved on the spring on described valve rod 22, and described spring one end is connected with described valve seat 21, and the other end is connected with described valve plate 23; Or described reply structure is compressing tablet, described compressing tablet one end is fixed on valve interior wall, and the other end is connected with the inner side of described valve plate 23.
During normal water supply, the air in pipeline enters in valve body, and automatic control pressure vent carries out normal exhaust work, and described valve plate 23 is in closed state.When there is negative pressure in pipeline, automatic vent valve outlet hole is opened, and starts air-breathing; Described valve plate 23 is opened under suction function, and sucks large quantity of air fast, until eliminate vacuum in pipe.During pipeline inner pressure balance, described valve plate 23 is closed, and is sealed into pore.
This programme gets rid of the air of separating out from water sustainably, and when there is negative pressure in pipeline, vacuum destroying mechanism action integrated in valve, sucks large quantity of air fast, to eliminate vacuum in pipe, prevents siphon from refluxing.This programme has the function of automatic control pressure vent and vacuum breaker valve concurrently, belongs to multi-purpose valve product.
Above an embodiment of the invention has been described in detail, but described content being only the preferred embodiment of the invention, the practical range for limiting the invention can not being considered to.All equalization changes done according to the invention application range with improve, within the patent covering scope that still all should belong to the invention.
