Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand and understand, the present invention is further explained below with reference to the accompanying drawings.
Referring to fig. 1, 2 and 3, the valve body of the air pressure unloading valve comprises a pressure regulating cavity (1), a piston cavity (2), an exhaust port (3), a one-way cavity (4) and a mounting end surface (5), and is characterized in that the mounting end surface (5) is respectively a first mounting end surface (a) and a second mounting end surface (b), the first mounting end surface (a) and the second mounting end surface (b) are in a step shape, wherein the first mounting end surface (a) is provided with two air vents which are respectively a first air vent (c), a second air vent (d) and a bolt fixing hole (e), the second mounting end surface (b) is provided with a one-way interface (f) and a bolt fixing hole (g), and the two air vents (c), (d) and the one-way interface (f) are arranged in the same direction. The utility model discloses constitute atmospheric pressure uninstallation valve with relevant part after, can rely on above-mentioned first installation terminal surface (a) and above that set up first interface (c), second interface (d) of ventilating, bolt fastening hole (e) and second installation terminal surface (b) and above that set up one-way interface (f), bolt fastening hole (g) to through sealing washer and bolt, closely and compactly fix in the air handling unit main part with atmospheric pressure uninstallation valve, constitute air handling unit assembly. If necessary, the air pressure unloader valve can be separately and conveniently removed from the air handling unit assembly for maintenance or replacement.
The pressure regulating cavity (1) is arranged on the side surface of the mounting end surface (5), and the axis (h) of the pressure regulating cavity is parallel to the mounting end surface (5). The structure of the air pressure unloading valve is more compact, and the space occupied by the air pressure unloading valve in the air processing unit assembly is reduced.
And the axis (j) of the piston cavity (2) and the axis (k) of the one-way cavity (4) are perpendicular to the mounting end surface (5). So set up, further reduced the occupation space in piston chamber (2) and one-way chamber (4), adapted more and connected with the correspondence of air handling unit main part contact surface.
The exhaust port (3) is arranged at the lower end of the piston cavity (2), and the axis (q) of the exhaust port is vertical to the axis (j) of the piston cavity (2). The air passage distance between the exhaust port (3) and the second air passage (d) and between the exhaust port and the piston cavity (2) is shorter, and the structure is more compact.
