Geometric modeling of wedge gate parts for ensuring the valves tightness

The aim of this work is to improve the quality of oil and gas valves with a rigid wedge in terms of integrity. The method of research presupposes modeling the geometrical specifications of the locking wedge in the coordinate system formed by the set of the major design datums of the wedge. This work result is tightness assurance of valves based on the separation of functions of the datums of the two wedge sealing surfaces into the sealing with informativeness three and the executive one with informativeness two. The datum with informativeness two is profiled in the form of two diametrically opposed areas on the wedge sealing surfaces and is used to make a sealing effort on the datum with informativeness three.The aim of this work is to improve the quality of oil and gas valves with a rigid wedge in terms of integrity.
