阅读说明：本技术 一种新结构阀片 (Valve plate with new structure ) 是由 田齐芳 郑春霞 田野 于 2019-01-10 设计创作，主要内容包括：一种新结构阀片是由2块成型板、1块折边型不锈钢薄片组成,其特征是成型板有2个梯形凸起和1个三角形凸起,折角型不锈钢薄片夹在2块成型板之间后铆接,折角型不锈钢薄片折角口紧贴其中1块成型板折角处底,阀片关闭时,阀片对折边型不锈钢薄片产生压力P,使折边型不锈钢薄片折角口紧贴成型板折角处底部,起密封作用。(The utility model provides a new construction valve block is by 2 profiled sheeting, 1 hem type stainless steel thin slice is constituteed, characterized by profiled sheeting has 2 trapezoidal archs and 1 triangle-shaped arch, dog-ear type stainless steel thin slice presss from both sides the back riveting between 2 profiled sheeting, dog-ear type stainless steel thin slice dog-ear mouth hugs closely wherein 1 profiled sheeting dog-ear bottom, when the valve block was closed, valve block produced pressure P to hem type stainless steel thin slice, make hem type stainless steel thin slice dog-ear mouth hug closely profiled sheeting dog-ear bottom, play sealed effect.)

1. The utility model provides a new construction valve block comprises 2 profiled sheeting, 1 hem type stainless steel thin slice, and characterized by profiled sheeting has 2 trapezoidal archs and 1 triangle-shaped arch, and dog-ear type stainless steel thin slice presss from both sides riveting behind between 2 profiled sheeting, and dog-ear type stainless steel thin slice dog-ear mouth hugs closely wherein 1 profiled sheeting dog-ear bottom.

Background

Most of the combined air valves are sealed by high-temperature-resistant silicone tubes, and the silicone tubes are easily abraded and corroded due to high humidity and much dust in the ventilation tunnels, so that the air discharge amount of the air valves is increased; according to the subway industry standard, the combined air valve passes a fire resistance integrity test for 2 hours at the temperature of 1000 ℃, and the silicone tube sealing strip cannot meet the test requirement.

Disclosure of Invention

The invention aims to overcome the defects of the original design, increase the strength of the valve plate, change the sealing mode, enhance the stability of the blade and reduce the air leakage rate.

The utility model provides a new construction valve block comprises 2 profiled sheeting, 1 hem type stainless steel thin slice, and characterized by profiled sheeting has 2 trapezoidal archs and 1 triangle-shaped arch, and dog-ear type stainless steel thin slice presss from both sides riveting behind between 2 profiled sheeting, and dog-ear type stainless steel thin slice dog-ear mouth hugs closely wherein 1 profiled sheeting dog-ear bottom.

In the figure, an original structure forming sheet (A), an original structure forming sheet (B) and a silicone tube sealing strip (C) are provided with 3 triangular bulges;

FIG. 2 is a cross-sectional view of a riveted valve plate

In the figure, an original structure forming sheet (A), an original structure forming sheet (B) and a silicone tube sealing strip (C) are provided with 3 triangular bulges;

FIG. 3 is a schematic view of 2 valve plates of original structure during sealing

In the figure, an original structure forming sheet (A), an original structure forming sheet (B), a silicone tube sealing strip (C) and a silicone tube sealing strip are clamped among 2 forming sheets and riveted to form a valve sheet, and the valve sheet is extruded and sealed by 2 silicone tube sealing strips (C);

FIG. 4 is a cross-sectional view of a valve plate of a new structure without riveting

In the figure, 2 new structure forming sheets (1) and a bevel type stainless steel sheet (2) are provided with 1 triangular bulge and 2 trapezoidal bulges;

FIG. 5 is a cross-sectional view of a valve plate with a new structure after riveting

In the figure, 2 new structure forming sheets (1) and a bevel type stainless steel sheet (2) are arranged;

FIG. 6 is a schematic view of the new valve plate structure

In the figure, 2 new structure forming sheets (1) and a bevel type stainless steel sheet (2) are arranged; when the valve plate is closed, the valve plate generates pressure P on the edge-folded stainless steel sheet, so that the corner opening of the edge-folded stainless steel sheet is tightly attached to the bottom of the corner of the forming plate, and the sealing effect is achieved.

Detailed Description

The utility model provides a new construction valve block is by 2 profiled sheeting, 1 hem type stainless steel thin slice is constituteed, characterized by profiled sheeting has 2 trapezoidal archs and 1 triangle-shaped arch, 2 trapezoidal archs have increased valve block intensity, dog-ear type stainless steel thin slice presss from both sides the back riveting between 2 profiled sheeting, dog-ear type stainless steel thin slice dog-ear mouth hugs closely wherein 1 profiled sheeting dog-ear department at the bottom, when the valve block was closed, valve block dog-ear type stainless steel thin slice produced pressure P, make hem type stainless steel thin slice dog-ear mouth hug closely profiled sheeting dog-ear department bottom, play the sealing action.
