Abstract
The utility model discloses a quick exhaust valve. The quick exhaust valve comprises an exhaust opening, a valve seat, a valve core, a housing, an air inlet and a working hole, wherein the valve seat is arranged in the housing; the working hole is formed in one side of the valve seat; the valve core is arranged at the lower end of the valve seat; and the exhaust opening and the air inlet are formed at two ends of the housing respectively. The exhaust opening of the exhaust valve is formed in a water outlet of a pump or in a water distribution pipeline, so that air accumulated in the pipeline is exhausted so as to improve the use efficiency of the pipeline and the water pump. Once negative pressure is generated in the pipeline, the quick exhaust valve can quickly inhale outside air for preventing the pipeline from being damaged due to the negative pressure. Moreover, the quick exhaust valve is reasonable in structure, easy to manufacture, low in cost and wide in application range.
Description
Technical field
The utility model relates to a kind of rapid escape valve.
Background technique
Society is for adapting to modern step now; A lot of factories have all adopted production line production; Make large-scale batch production become possibility, human daily life environment also progressively to automation and intelligent direction development, makes outlet valve all can use in pipeline exhausts such as independent heating system, central heating system, heating boiler, central air-conditioner, floor heating and solar heating system or the like; But the exhaust structure on the market is complicated; In a single day cost is high, and when producing negative pressure in the pipeline, causes pipeline to damage because of negative pressure easily.
The model utility content
The model utility purpose: the purpose of the utility model is in order to solve the deficiency of existing technology, to provide a kind of simple in structure, and cost is low, and can effectively prevent the rapid escape valve that pipeline damages because of negative pressure.
Technological scheme: in order to realize above purpose, the described a kind of rapid escape valve of the utility model, it comprises relief opening, valve seat, spool; Housing; Suction port and working hole are provided with valve seat in the described housing, and a side of valve seat is provided with working hole; The lower end of described valve seat is provided with spool, and the two ends of housing are respectively equipped with relief opening and suction port.
Described spool be horn-like and horn mouth down.
Beneficial effect: a kind of rapid escape valve that the utility model provides; Through being installed in, this relief opening pumps in place, the mouth of a river or the water distribution pipeline; In a single day thereby realize getting rid of aggregation at ducted air, to improve the utilization efficiency of pipeline and water pump, when producing negative pressure in the pipeline; This rapid escape valve can suck ambient air rapidly, damages because of negative pressure to prevent pipeline.And this exhaust structure is reasonable, and is easy to manufacture, and cost is low, so the application is extensive.
Description of drawings
Fig. 1 is the whole-cutaway view of the utility model.
Embodiment
Below in conjunction with accompanying drawing, further illustrate the utility model.
As shown in Figure 1, the described a kind of rapid escape valve of the utility model, it comprises relief opening 1, valve seat 2, spool 3, housing 4, suction port 5 and working hole 6.Be provided with horn-like in the described housing 4 and horn mouth valve seat 2 down, a side of described valve seat 2 is provided with working hole 6, and the lower end of valve seat 2 is provided with spool 3, and the two ends of housing 4 are respectively equipped with relief opening 1 and suction port 5.
When suction port 5 input service gases, move on the horn-like spool 3, at this moment, close valve seat 1, working gas arrives working hole 6 by the horn-like avris of spool 2.
When the no working gass input of suction port 5, under the effect of the differential pressure of working hole 6 and suction port 5, spool 3 descends rapidly, and at this moment, working hole 5 is closed, and then, by suction port 5 and relief opening 1 connection, has realized quick exhaust.
This outlet valve pumps in place, the mouth of a river or the water distribution pipeline through this relief opening 1 is installed in; Thereby realize getting rid of aggregation at ducted air; To improve the utilization efficiency of pipeline and water pump; In a single day when producing negative pressure in the pipeline, this rapid escape valve can suck ambient air rapidly, damages because of negative pressure to prevent pipeline.And this exhaust structure is reasonable, and is easy to manufacture, and cost is low, so the application is extensive.
Above-mentioned mode of execution only is the technical conceive and the characteristics of explanation the utility model, its objective is to let to be familiar with the also enforcement according to this of content that these those skilled in the art can understand the utility model, can not limit the protection domain of the utility model with this.All equivalents or modifications of being made according to the utility model spirit all should be encompassed within the protection domain of the utility model.
