Abstract
The utility model provides a guide structure of an exhaust valve buoy, which comprises a valve body, a buoy and a floating ball, wherein the valve body is provided with a valve body; the floating ball is arranged in the valve barrel and is connected with the floating barrel; the valve body inboard is equipped with a plurality of direction platforms, the flotation pontoon outside is equipped with a plurality of pairs of bosss, and every recess between to the boss with the direction platform cooperatees. The guide table on the inner side of the valve body is matched with the groove on the outer side of the float bowl, so that the float bowl vertically moves up and down, the float bowl is not blocked in the exhaust process, the exhaust is stable, and meanwhile, the guide table on the valve body increases the strength of the valve body.
Description
Technical Field
The utility model belongs to the technical field of exhaust valves, and particularly relates to a guide structure of an exhaust valve buoy.
Background
The exhaust valve is applied to exhaust of pipelines such as an independent heating system, a central heating system, a heating boiler, a central air conditioner, a floor heating system, a solar heating system and the like. When gas overflows from the system, the gas ascends along the pipeline and finally gathers at the highest point of the system, the exhaust valve is generally installed at the highest point of the system, when the gas enters the valve cavity of the exhaust valve and gathers at the upper part of the exhaust valve, the pressure rises along with the increase of the gas in the valve, when the gas pressure is higher than the system pressure, the gas can enable the water surface in the cavity to fall, the buoy falls along with the water level, and the exhaust port is opened; after the gas is exhausted, the water level rises, the buoy also rises along with the water level, and the exhaust port is closed. In the same way, when negative pressure is generated in the system, the water level in the valve cavity is lowered, the exhaust port is opened, and the outside atmospheric pressure is higher than the system pressure, so that the atmosphere can enter the system through the exhaust port, and the negative pressure is prevented from being damaged. In the traditional exhaust valve, the valve body and the float bowl are not matched in a guiding way, so that the float bowl is easy to block in the exhaust process, and the unstable exhaust condition occurs.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides the guide structure of the vent valve float bowl, the valve body is in guide fit with the float bowl, the float bowl is not blocked in the venting process, and the venting is stable.
In order to achieve the purpose, the technical scheme adopted by the utility model is as follows:
the utility model provides a guide structure of an exhaust valve buoy, which comprises a valve body, a buoy and a floating ball, wherein the valve body is provided with a valve body; the floating ball is arranged in the valve barrel and is connected with the floating barrel; the valve body inboard is equipped with a plurality of direction platforms, the flotation pontoon outside is equipped with a plurality of pairs of bosss, and every recess between to the boss with the direction platform cooperatees.
Preferably, the floating ball is connected with the buoy through a pin.
Preferably, four guide platforms are uniformly arranged on the inner side of the valve body, four pairs of bosses are arranged on the outer side of the buoy, and the grooves between each pair of bosses are matched with the guide platforms.
The utility model has the following beneficial effects:
the utility model provides a guide structure of an exhaust valve buoy, wherein the buoy is arranged in a valve body, a floating ball is arranged in a valve barrel, and the floating ball is connected with the buoy; the inner side of the valve body is provided with a plurality of guide platforms, the outer side of the buoy is provided with a plurality of pairs of bosses, and the grooves between each pair of bosses are matched with the guide platforms. The air in the pipeline enters through the lower end of the valve body and is discharged from the upper end, after the air in the pipeline is emptied, the water enters the exhaust valve to enable the floating cylinder and the floating ball to rise under the action of buoyancy, and the air inlet and the air outlet are sealed to realize exhaust. The guide table on the inner side of the valve body is matched with the groove on the outer side of the float bowl, so that the float bowl vertically moves up and down, the float bowl is not blocked in the exhaust process, the exhaust is stable, and meanwhile, the guide table on the valve body increases the strength of the valve body.

Detailed Description
In order to make the technical solutions of the present invention better understood, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
The embodiment provides a guide structure of an exhaust valve float, as shown in fig. 1 to 5, comprising a valve body 1, a float 2 and a floating ball 3; the float 2 is arranged in the valve body 1, the floating ball 3 is arranged in the valve barrel 2, and the floating ball 3 is connected with the float 2 through a pin 4; the inboard a plurality of direction platforms 11 that are equipped with of valve body 1, the flotation pontoon 2 outside is equipped with a plurality of pairs of bosss 21, and every recess 22 between every pair of boss 21 with direction platform 11 cooperatees. In this embodiment, four guide platforms 11 are uniformly arranged on the inner side of the valve body 1, four pairs of bosses 21 are arranged on the outer side of the float 2, and the grooves 22 between each pair of bosses 21 are matched with the guide platforms 11.
The working process is as follows: the air in the pipeline enters through the lower end of the valve body 1 and is discharged from the upper end, after the air in the pipeline is emptied, the water enters the exhaust valve to enable the floating cylinder 2 and the floating ball 3 to rise under the action of buoyancy, and the air inlet and the air outlet are sealed to realize exhaust.
According to the technical scheme, the guide structure of the vent valve buoy provided by the embodiment has the advantages that the buoy vertically moves up and down due to the cooperation of the guide table on the inner side of the valve body and the groove on the outer side of the buoy, the buoy is free of blocking in the exhaust process, the exhaust is stable, and meanwhile the strength of the valve body is increased by the four guide tables on the valve body.
The embodiments of the present invention have been described in detail through the embodiments, but the description is only exemplary of the embodiments of the present invention and should not be construed as limiting the scope of the embodiments of the present invention.
