Abstract
The utility model relates to an exhaust limiting plate and rotor compressor, including stiff end and the spacing section of arc, the stiff end is used for compressing tightly the exhaust valve piece, the spacing section of arc is equipped with spacing face, spacing face is used for limiting the maximum aperture of exhaust valve piece, the position of contact with the valve tongue of exhaust valve piece is equipped with the hole on the spacing face, when the valve tongue contacts with spacing face, the hole is covered completely by the valve tongue; the utility model provides the high life of discharge valve piece, and then can improve the life of compressor.
Description
Technical Field
The utility model relates to a compressor technical field specifically is an exhaust limiting plate and rotor compressor.
Background
The rotor compressor has the process of breathing in and exhausting when moving, and during the exhaust, the discharge valve piece outwards patted rapidly under the impact of high-pressure exhaust, and the frequent switching of discharge valve piece is patted back and forth between valve plate and exhaust limiting plate, and the discharge valve piece is easy to produce fatigue after receiving the power of beating of valve plate and limiting plate repeatedly for a long time, breaks even, directly influences the life of compressor.
Disclosure of Invention
The utility model aims at providing a life who promotes the discharge valve piece provides an exhaust limiting plate and rotor compressor.
The utility model has the following concrete scheme: the exhaust limiting plate comprises a fixed end and an arc-shaped limiting section, wherein the fixed end is used for compressing an exhaust valve plate, the arc-shaped limiting section is provided with a limiting surface, the limiting surface is used for limiting the maximum opening of the exhaust valve plate, a hole is formed in the limiting surface at the position, in contact with a valve tongue of the exhaust valve plate, and when the valve tongue is in contact with the limiting surface, the hole is completely covered by the valve tongue.
The holes of the utility model are round or oval or waist-round.
Stiff end bottom is equipped with the straightway, and the straightway is tangent with the spacing section of arc.
Exhaust limiting plate is along central line self-symmetry.
The utility model also provides a rotor compressor, the valves includes the cylinder cap, goes up the cylinder cap and is equipped with the exhaust hole, and exhaust hole department is equipped with the mounting groove, and the mounting groove internal fixation is equipped with discharge valve piece and exhaust limiting plate, the exhaust limiting plate adopts above-mentioned exhaust limiting plate.
The utility model discloses a theory of operation as follows: the exhaust valve plate is provided with the holes, so that the contact area between the valve tongue of the exhaust valve plate and the limiting plate is reduced, the impact force between the valve tongue and the exhaust limiting plate can be reduced, and the service life of the exhaust valve plate is prolonged.
Compared with the prior art, the utility model has the following advantages: the service life of the exhaust valve plate is prolonged, and the service life of the compressor can be prolonged.
