Problems solved by technology

However, the existing design method for the spool profile of the conical throttle valve adopts the iterative method of preliminary modeling, differential pressure characteristic calculation, and modeling optimization, and cannot directly introduce the influence of the differential pressure characteristic of the throttle valve on the spool type in the design process. The influence of the surface greatly limits the efficiency of the design of the conical throttle valve spool

Embodiment Construction

[0026] In order to make the technical purpose, technical solution and technical advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples of implementation.

[0027] figure 1 , figure 2 They are respectively a three-dimensional longitudinal section view and a two-dimensional longitudinal section view of a typical conical throttle valve. The conical throttle valve consists of a valve core 1 and a housing 2 forming an axisymmetric fluid channel, wherein the valve core profile 11 is a rotary surface, and the inner wall surface 21 of the housing is also a rotary surface. Spool 1 can be along figure 1 Move in the direction indicated by the double arrow in the center. During the movement of the spool 1, a certain weft circle on the spool surface 11 and a fixed weft circle on the inner wall surface 21 of the housing form the throat section 3 with the smallest flow area (such...

Abstract

The invention relates to a profile design method of a valve plug of a conical throttle valve with controlled pressure differential characteristics. The profile design method achieves profile design of the valve plug of the throttle valve by controlling the area of a throat of the conical throttle valve, and aims to improve the control capability of profile design of the valve plug of the conical throttle valve in incompressible flow on the pressure differential characteristics of the throttle valve. The profile design method achieves profile design of the valve plug by building the mathematical relational expressions of the relative displacement amount of the conical throttle valve pressure differential in incompressible flow, the area of the throat of the throttle valve, the valve plug of the throttle valve and a casing and controlling the area of the throat at different valve plug positions according to the requirements of the conical throttle valve pressure differential, avoids the repeated circulative iteration process of the traditional design method, can greatly improve the efficiency of profile design of the conical throttle valve, and is applicable to the profile design of the valve plug of the conical throttle valve of the incompressible flow field.

Description

technical field [0001] The invention relates to the design field of a conical throttle valve in pipeline flow, and is a method for modeling the spool of a conical throttle valve according to the pressure difference characteristic requirements of the throttle valve, specifically a conical throttle valve Controllable differential pressure characteristic spool profile design method. Background technique [0002] The use of conical throttle valves in pipeline flow is very common, not only widely used in industrial production fields, but also widely used in various fluid test devices. The change law of the static pressure difference between the inlet and outlet sections of the throttle valve with the opening of the throttle valve, that is, the pressure difference characteristics of the throttle valve, mainly includes linear pressure difference characteristics, equal percentage pressure difference characteristics, parabolic pressure difference characteristics and quick opening pre...
