Problems solved by technology

[0002] At present, most of the check pieces / valves in the flue check valve are double-opening doors arranged up and down or left and right, and a few are single-piece valves, but they basically cannot be fully opened in the valve body, so the indoor oil fume cannot be completely discharged. Lead to indoor pollution and endanger people's physical and mental health in severe cases
In higher floors, due to the existence of negative pressure, the check piece / valve cannot be completely closed after opening, which will also affect the use effect of the check valve

Embodiment Construction

[0018] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0019] Such as Figure 1-2 As shown, the zero-resistance flue check valve of the present invention includes a valve body 1, which can be composed of a square shell 100 and an upper cover 101 located at one end of the square shell 100, wherein an air hole 2 is opened in the middle of the upper cover 101, And a section extends outward from the air hole 2 to form an external connection 102 , and an upper cover level 107 can be provided on the upper cover 101 as required. The present invention is provided with a monolithic valve 3 at the vent hole 2. One side of the valve 3 extends outward for a section and passes through the side wall of the valve body to bend obliquely. The width of the upper and lower ends of the bent part is not equal. Install door shaft 4 at the bent end, such as Figure 3-4 As shown, since the width of the upper end of the...

Abstract

The invention discloses a zero-resistance flue check valve which comprises a valve body, wherein a vent hole is formed in the valve body; a single-piece valve is arranged at the vent hole of the valve body; a section extends out of one side of the single-piece valve, penetrates the side wall of the valve body and then is slantwise bent; the upper end and the lower end of the bent section have unequal widths; a pivot is mounted at the tail end of the bent section; and the single-piece valve can be completely opened in the valve body around the pivot. The zero-resistance flue check valve provided by the invention can be completely opened, thoroughly realizes a straight-through, zero-resistance and direct-discharge flue and is greatly improved in exhaust ventilation efficiency.

Description

technical field [0001] The invention relates to a flue check valve, in particular to a zero-resistance flue check valve. Background technique [0002] At present, most of the check pieces / valves in the flue check valve are double-opening doors arranged up and down or left and right, and a few are single-piece valves, but they basically cannot be fully opened in the valve body, so the indoor oil fume cannot be completely discharged. Cause indoor pollution, endanger people's physical and mental health when serious. In higher floors, due to the existence of negative pressure, the check piece / valve cannot be completely closed after opening, which will also affect the use effect of the check valve. [0003] Therefore, urgently need to solve the above-mentioned problem. Contents of the invention [0004] Purpose of the invention: The purpose of the invention is to provide a flue check valve with direct air discharge and zero resistance. [0005] Technical solution: The zero-r...
