Embodiment Construction

[0020] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0021] like figure 1 As shown, the exhaust valve includes a valve shell 1, the valve shell 1 is provided with an inner cavity 111, the upper end of the valve shell 1 has an exhaust hole 2 that communicates with the inner cavity 111, and the lower end of the valve shell 1 has an inner cavity 2 connected to the inner cavity 111. 111 is connected to the water inlet hole 3.

[0022] Preferably, in this embodiment, the valve housing 1 includes a valve body 11 and a valve cover 12, the lower end of the valve cover 12 is connected to the upper end of the valve body 11, and the exhaust hole 2 is opened on the valve cover 12 to facilitate the operation of the exhaust valve. Install. Of course, as another solution, the exhaust hole 2 can also be designe...

Abstract

The invention belongs to the technical field of valves, and relates to a float type exhaust valve, which solves the problems of complex structure and high production cost of the existing exhaust valve. The exhaust valve includes a valve shell, the valve shell is provided with an inner cavity, the upper end of the valve shell has an exhaust hole communicated with the inner cavity, the lower end of the valve shell has a water inlet hole communicated with the inner cavity, and the inner cavity A float that can move in the vertical direction is provided, the upper end of the float is provided with a sealing part that can seal the exhaust hole, and the float and the sealing part are integral structures. In this application, the sealing part and the float are designed as one piece, which can effectively simplify the overall structure of the exhaust valve and reduce the production cost.

Description

technical field [0001] The invention belongs to the technical field of valves, and relates to a float type exhaust valve. Background technique [0002] With the continuous development of the economy, there are more and more long-distance water delivery projects in cities, and due to the influence of various use environments such as topography and landforms. The water pipeline will also fluctuate, and the phenomenon of local gas accumulation will be formed in the pipeline. In order to solve this problem, an exhaust valve is usually designed at the highest point of the pipeline or where the gas is closed to discharge the gas in the pipeline. [0003] In addition, in some mechanical equipment, such as water pumps, an exhaust valve is also designed, and the water pump needs to discharge the air in the equipment every time it is turned on. [0004] Therefore, the use of exhaust valves is related to all aspects of people's life and work, and many manufacturers have also conducte...
