Abstract
The invention provides a valve capable of regulating pressure drop and belongs to the field of valves. The valve comprises a valve body, a sleeve, a sliding plate, a valve rod, a sliding plate rod, a sleeve support, a valve rod positioning base and a sliding plate rod support. The valve rod is in linkage connection with a sliding plate rod in the valve body, the sliding plate rod drives the sliding plate to perform piston motion in the sleeve along the axial direction of the valve, and holes are arranged on the side wall of the sleeve and the sliding plate according to a certain rule. The valve capable of regulating the pressure drop overcomes the defect that when an existing typical valve is operated, medium in a pipe is easy to form turbulence so as to lead a pipe system to vibrate, operation torsion is large, and regulation is inflexible, is small in operation torque, and regulates flexibility of regulation medium pressure and flow.
Description
Technical field
The invention belongs to valve field, be specifically related to the valve that a kind of adjustable pressure falls.
Background technique
Valve is widely used in the pipe-line transportation system of many industrial fields such as oil, chemical industry, light industry, pharmacy, play and connect and cut off medium, regulate the effects such as pressure medium and flow, but due to the intrinsic structural type of existing typical valve (gate valve, stop valve, ball valve and butterfly valve etc.), also there is following deficiency: 1, during valve operation simultaneously, easily cause medium flow pattern to change, pipeline internal medium forms turbulent flow, causes that pipe-line system vibrates; 2, valve operation moment of torsion is larger, regulates pressure medium and flow underaction.
Along with developing rapidly of petrochemical industry, ten million ton of oil refining more in recent years and megaton ethane project are constructed and put into operation in succession, the more and more large-scale change of unit scale, and unit capacity is increasing, and pipe diameter reaches 3 meters of left and right.Impact due to the market demand, the actual treatment amount of device often changes, the pressure of medium and flow also respective change are larger, the defect of adding on conventional valve mechanism causes pipe vibration aggravation, particularly, in the large gas-liquid two-phase occasion of pressure surge, pipe-line system oscillation phenomenon often has generation.In the occasion of larger occasion, particularly gas-liquid two-phase flow of some pressure medium fluctuations, valve not only can not play the effect of voltage stabilizing, but also because structural defect has been aggravated the vibration of pipeline, so the innovation of valve mechanism has become the key of technological development.
Summary of the invention
While the object of the invention is to solve existing conventional valve operation, easily cause medium flow pattern to change, pipeline internal medium forms turbulent flow, cause that pipe-line system vibrates, and valve operation moment of torsion is larger, regulate the deficiency of the aspects such as pressure medium and flow underaction, the valve that provides a kind of adjustable pressure to fall, can carry out the pressure of manual tune pipe-line system according to the fluctuation of pressure, play the effect of voltage stabilizing, thereby restrain the vibration of pipeline, it is specially adapted to Two-phase Flow Pipeline Transport.
The present invention is achieved by the following technical solutions:
A valve falls in adjustable pressure, comprises valve rod 1 and valve body 2; Sleeve 4 is installed in the valve pocket of described valve body 2, described sleeve 4 and valve pocket coaxial line (axis of valve pocket is the axis of valve).
