Problems solved by technology

Its disadvantages are: the flat base is not easy to drain, and the corners are easy to accumulate sludge and impurities; and when there are sludge and impurities near the flat valve seat, it is easy to damage the airtight running-in performance, causing hot air to enter through the gap or cold air to leak, reducing the refrigeration efficiency
The condensed water is removed through the flat water leakage port, whether it is a flat valve body or a spherical valve body, there is only one sealing function, and the spherical valve body is not easy to achieve true roundness
If it is an injection plastic joint, the joint line cannot be in close contact with the base to achieve an airtight effect

Embodiment 1

[0014] Embodiment 1: see attached figure 1 .

[0015] The shape of the float is disc-shaped, and the lower half of the float 1 has a multi-circle ring-shaped flange 2, and the inner surface of the valve seat matched with it is also disc-shaped.

Embodiment 2

[0016] Embodiment 2: see attached figure 2 .

[0017] The shape of the float is conical, and the lower half of the float 1 has a multi-circle ring-shaped flange 2, and the inner surface of the valve seat matched with it is also conical.

Embodiment 3

[0018] Embodiment 3: see attached image 3 .

[0019] The shape of the float is a cone, and its outer surface is a curved surface. The lower half of the float 1 has a multi-circle ring-shaped flange 2, and the inner surface of the valve seat matched with it is also of the same cone shape.

Abstract

This invention relates to a multi-sealing floater used in liquid and gas pipe sealing, which has the following structure: the floater down part has one round ring protruding edge; the floater takes shapes from disc shape, taper, column, or ball or prism or cuboid. The invention adds multi-layer ring protruding edges on down part to form multiple sealing surfaces with the bottom socket with same shape to generate the sealing effect without any demands of vacuum round degree.

Description

technical field [0001] The invention belongs to a float used for sealing in liquid or gas pipelines, and particularly relates to the improvement of its structure. Background technique [0002] Existing floats used for sealing in liquid or gas pipelines, for example, floats in automatic drainage devices in compressed air systems, floats in household water tanks, and their structures are spherical float valve bodies or flat valve bodies, The valve seat matched with it is a flat base. The disadvantages are: the flat base is not easy to drain, and the corners are easy to accumulate sludge and impurities; and when there are sludge and impurities near the flat valve seat, it is easy to damage the airtight running-in performance, causing hot air to enter through the gap or cold air to leak, reducing the refrigeration efficiency . The condensed water is drained through the flat leaking port. Whether it is a flat valve body or a spherical valve body, there is only one important sea...
