Description

Technical Field

[0001] The invention relates to the field of building ventilation equipment, in particular to a wall valve suitable for a building fresh air system. Background Art

[0002] The fresh air system of a building usually has one set of fresh air system for one building unit, that is, there is one air supply vent and one air outlet. When there are more than two rooms, one room is equipped with an air supply vent. When the air volume in the room reaches saturation, it is sent to the next room through the pressure relief wall valve, and so on. Finally, the air is discharged to the outside through the air outlet, so as to achieve the circulation of indoor air in the rooms of the entire unit.

[0003] The traditional approach is:

[0004] 1. The pressure relief wall valve directly uses a straight-through hollow tube or grille vent, so the sound insulation between rooms is very poor; 2. Each room is equipped with air supply and outlet, which requires adding a lot of pipes and equipment to each room, increasing costs, and some rooms are limited and cannot be installed with pipes and equipment. Summary of the invention

[0005] The present invention provides a blind passage pressure relief wall valve, which aims to solve the shortcomings of the prior art, improve the sound barrier effect of the pressure relief wall valve, simplify pipeline equipment and reduce costs.

[0006] The technical solution adopted by the present invention to solve its technical problem is:

[0007] Blind channel pressure relief wall valve, characterized by:

[0008] One side of the square valve plate is a plate slot side, and more than two plate slots are provided on the plate slot side. The valve plate areas on both sides of each plate slot are respectively a ventilation hole area and a side hole area;

[0009] A ventilation hole is provided in the middle of the ventilation hole area of ​​the valve plate, and a slot-shaped side hole is provided on the side of the inserting slot in the side hole area;

[0010] More than two longitudinal valve sheets arranged vertically and more than two transverse valve sheets arranged horizontally are perpendicular to each other.

[0011] The longitudinal valve plate insert slots are opened upward, and the ventilation hole areas of adjacent longitudinal valve plates correspond to the side hole areas;

[0012] The transverse valve plate insert slot opening faces downward, and the ventilation hole area of ​​the adjacent transverse valve plates corresponds to the side hole area;

[0013] The inserting slot of the transverse valve sheet is aligned with the inserting slot of the longitudinal valve sheet and inserted, the inserting slot of the transverse valve sheet clamps the lower part of the inserting slot of the longitudinal valve sheet, and the inserting slot of the longitudinal valve sheet clamps the upper part of the inserting slot of the transverse valve sheet, so as to form a combination of the longitudinal valve sheet and the transverse valve sheet;

[0014] The combination of the longitudinal valve sheet and the transverse valve sheet is accommodated in a shell body with an air inlet and an air outlet to form a valve body.

[0015] The shell is composed of more than 4 side panels, which are fixed to the upper, lower, left and right sides of the combination of the longitudinal valve sheet and the transverse valve sheet to form a valve body, and the front and rear openings of the valve body are air inlet and air outlet.

[0016] The valve plate is made of bamboo fiber.

[0017] The depth of the insert slot is half the width of the valve plate.

[0018] The valve plate is also provided with a slot-shaped side hole on another side opposite to the side of the inserting plate groove.

[0019] The present invention is beneficial in that:

[0020] The present invention uses flexibly combined valve sheets to form a blind path structure, which not only plays a role in pressure relief, but also makes the propagation of sound subject to multiple obstacles. The blind path pressure relief wall valve has a better sound barrier effect. The material is bamboo fiber, which can inhibit the growth of bacteria and viruses, and the material is fluffy to prevent hard sound transmission. It only needs to be installed on the wall between rooms, and does not require many pipes and equipment, thereby simplifying the pipeline equipment and reducing costs.

[0026] In order to more clearly illustrate the technical solution of the present invention, the following will briefly introduce the drawings required for the description. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other embodiments can be obtained based on these drawings without creative work. In order to facilitate the understanding of the present invention, the present invention is described in more detail below in combination with the drawings and specific embodiments.

[0027] It should be noted that when an element is described as being "fixed to" another element, it may be directly on the other element, or one or more centered elements may exist therebetween. When an element is described as being "connected" to another element, it may be directly connected to the other element, or one or more centered elements may exist therebetween. The terms "upper", "lower", "inner", "outer", "bottom", etc. used in this specification indicate an orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", "third", etc., etc. are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0028] like Figure 1 As shown:

[0029] The valve sheet A of the present invention is a rectangular bamboo fiber sheet with a size of 120 mm in length and 60 mm in width. The bamboo fiber is made of bamboo fiber, which can inhibit the growth of bacteria and viruses, and the material is fluffy to prevent hard sound transmission.

[0030] One side thereof is a sheet inserting groove side B, on which five sheet inserting grooves C with a depth of 30 mm are opened, that is, the depth of the sheet inserting grooves C is half of the width of the valve plate A.

[0031] The valve plate areas on both sides of each insert slot C are respectively a ventilation hole area D and a side hole area E.

[0032] The valve plate A is provided with a ventilation hole F in the middle of the ventilation hole area D, which has a size of 30 mm in length and 10 mm in width.

[0033] The valve plate A has a slot-shaped side hole G with a length of 15 mm and a width of 10 mm on the side B of the insert slot in the side hole area E, and also has a slot-shaped side hole H with a length of 15 mm and a width of 10 mm on the other side opposite to the side B of the insert slot.

[0034] like Figure 2 As shown:

[0035] The five longitudinal valve sheets 1 are arranged longitudinally and in parallel, with the inserting slots C opening upward, and the ventilation hole areas D and the side hole areas E of adjacent longitudinal valve sheets 1 correspond to each other.

[0036] That is, the ventilation hole F of one longitudinal valve sheet 1 corresponds to a position without openings in the middle of the side hole area E of its adjacent longitudinal valve sheet 1. In this way, after the airflow passes through the ventilation hole F of one longitudinal valve sheet 1, it cannot directly pass through the adjacent longitudinal valve sheet 1, but is blocked by the adjacent longitudinal valve sheet 1 and separated to the four sides.

[0037] Furthermore, the side hole G or the side hole H of a longitudinal valve sheet 1 corresponds to a position without openings in the upper or lower part of the ventilation hole area D of its adjacent longitudinal valve sheet 1. In this way, after the airflow passes through the side hole G or the side hole H of a longitudinal valve sheet 1, it cannot directly pass through the adjacent longitudinal valve sheet 1, but is blocked by the adjacent longitudinal valve sheet 1 and separated to the four sides.

[0038] like Figure 3 As shown:

[0039] Place another five transverse valve sheets 2 perpendicular to the five longitudinal valve sheets 1 , that is, the five transverse valve sheets 2 are arranged in parallel and transversely. Like the longitudinal valve sheets 1 , the ventilation hole areas D and side hole areas E of adjacent transverse valve sheets 2 correspond to each other.

[0040] Moreover, the inserting slots C of the five transverse valve plates 2 face downward, and the inserting slots C of the transverse valve plates 2 are aligned with the inserting slots C of the longitudinal valve plates 1 and inserted downward, so that the inserting slots C of the transverse valve plates 2 clamp the portion below the inserting slots C of the longitudinal valve plates 1, and the inserting slots C of the longitudinal valve plates 1 also clamp the portion above the inserting slots C of the transverse valve plates 2.

[0041] The five inserting slots C of each transverse valve sheet 2 clamp the five longitudinal valve sheets 1 , and the five inserting slots C of each longitudinal valve sheet 1 clamp the five transverse valve sheets 2 .

[0042] The five longitudinal valve sheets 1 and the five transverse valve sheets 2 are combined together.

[0043] like Figure 4 As shown:

[0044] The four side panels 3 are bonded to the upper, lower, left and right sides of the combination of the five longitudinal valve sheets 1 and the five transverse valve sheets 2 to form a valve body 4. The front and rear openings of the valve body 4 are an air inlet 41 and an air outlet 42. This is a blind pressure relief wall valve. The four side panels 3 constitute a shell.

[0045] The blind passage pressure relief wall valve is installed on the wall between rooms (generally installed above the door). When the air volume in a room reaches saturation, the wind enters the blind passage pressure relief wall valve through the air inlet 41 and enters the next room from the air outlet 42. Since the five longitudinal valve plates 1 and the five transverse valve plates 2 are combined together, the ventilation holes F, side holes G, and side holes H inside form a tortuous passage in the form of a maze, so the wind cannot pass directly through, which makes the propagation of sound subject to multiple obstacles. The blind passage pressure relief wall valve has a better sound isolation and transmission effect; and it only needs to be installed on the wall between rooms, without requiring many pipes and equipment, thereby simplifying the pipeline equipment and reducing costs.

[0046] In this specification, each embodiment is described in a progressive manner, and each embodiment focuses on the differences from other embodiments, and the same and similar parts between the embodiments can be referred to each other. The above description of the disclosed embodiments enables professionals and technicians in this field to implement or use the present invention. Various modifications to these embodiments will be obvious to professionals and technicians in this field, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown in this article, but will comply with the widest range consistent with the principles and novel features disclosed herein.
