Constructive Disposition Introduced in Reciprocating Compressor Suction Valve

Abstract

Constructive disposition introduced in reciprocating compressor suction valve, whose moving parameters of elastic flexion area and, therefore, sealing end are mainly defined by specific geometries and dimensions of the own flexible segment of suction valve. Furthermore, the stiffness coefficient and natural frequency of flexible segment of suction valve are also defined from specific geometries and dimensions of the own flexible segment of suction valve, without being necessary to alter the material or thickness of metallic blade where the suction valve is defined.

1 . Constructive disposition introduced in reciprocating compressor suction valve, comprising:
 a rigid blade having at least one semi-surrounding hollow slot which defines at least one flexible segment; said flexible segment comprising at least one sealing end, at least one elastic flexion area, at least one passing port, and at least one crimping area; aid flexible segment further comprising the following dimensions:   “H” dimension, which comprises a general longitudinal extension of flexible segment;   “L” dimension, which comprises a general latitudinal extension of flexible segment;   dimension, in which “C” comprises the general longitudinal extension of passing port of flexible segment;   “R 1 ” dimension, which comprises the upper internal surrounding radius of passing port of flexible segment;   “R 2 ” dimension, which comprises the lower internal outline radius of passing port of flexible segment;   “B 1 ” dimension, which comprises the latitudinal straight distance between the insertion point between the imaginary circle “CR 1 ” and the most outstanding portion of the superior internal outline radius of passing port of flexible segment and the external outline point of flexible segment closer to the interception point between the imaginary circle “CR 1 ” and the most outstanding portion of upper internal outline radius of passing port of flexible segment;   “B 2 ” dimension, which comprises the latitudinal straight distance between the interception point between the imaginary circle “CR 2 ” and the most outstanding portion of lower internal outline radius of passing port of flexible segment and the external outline point of flexible segment closer to the interception point between the imaginary circle “CR 2 ” and the most outstanding portion of lower internal outline radius of passing port of flexible segment;   said constructive disposal introduced on a reciprocating compressor suction valve being specially characterized by:   the “H” dimension is larger than “L” dimension in a ratio which can vary between 1.31:1 to 1.9:1;   the “H” dimension is larger than “C” dimension in a ratio which can vary between 1.61:1 to 2.5:1;   the “R 2 ” dimension is larger than “R 1 ” dimension in a ratio which can vary between 1.1:1 to 1.7:1; and   the “B 2 ” dimension is larger than “B 1 ” dimension in a ratio which can vary between 1.2:1 to 1.8:1.
