Description
Technical field
The present invention relates to a kind of flow control system of protection against erosion wearing and tearing of the pipe-line system that contains a large amount of hard solid particles for medium.
Background technique
For some pipe-line system, not only need switch to control, also need the parameters such as flow in regulation and control pipeline.For the pipe-line system that contains a large amount of hard solid particles in medium, conventionally adopt ball valve as the control valve of pipe-line system, conventionally ball valve is only controlled for the switch of pipe-line system, if adopt ball valve to carry out adjusting and the control of flow, needs to realize by changing the aperture of ball valve.Accompanying drawing 1 is by changing the aperture of ball valve, to carry out the situation of regulation and control flow, now ball valve is in the position that part is opened, due to dwindling of channel cross-section A and cross section B area, therefore flow that can regulation and control pipe-line system, but cause the rate of flow of fluid at this position to increase simultaneously, but also changed the flow circuits of medium, make high-velocity fluid directly be washed into sphere inner wall and valve interior wall, while containing hard solid particle in medium, fluid high-speed with hard solid particle washes away the erosive wear that is easy to cause spheroid C position and valve body D position, the aperture of spheroid is less, the pressure reduction of fluid is larger, the rate of flow of fluid of ball valve local location is just larger, valve is more easily washed wearing and tearing, when in fluid, the content of hard solid particle is higher, valve is more easily washed wearing and tearing.Therefore, for the medium operating mode containing hard solid particle, ball valve is conventionally only applicable to the switch of pipe-line system and controls, and is not suitable for Flow-rate adjustment and the control of pipe-line system.
In Practical Project, user has following usage requirement: the medium in pipe-line system contains a large amount of hard solid particles, when pipe-line system pressure is higher, need to carry out by valve the flow of regulation and control pipeline medium, avoid having an accident because flow is excessive, and pressure decreased in pipeline is after the pressure of regulation, require the unimpeded medium that makes of pipeline to discharge rapidly.
For containing a large amount of hard solid particles in medium, conventionally select ball valve as the control valve of pipeline, and during ball valve full open, pipeline is completely unimpeded, can meet the medium requirement of discharge rapidly, but system requirements need to carry out adjust flux by valve when loine pressure is higher, according to analysis above, when ball valve is used for containing the Flow-rate adjustment of hard solid particle medium, valve is easy to damage because of erosive wear, therefore, only adopts a billiard ball valve cannot meet user's usage requirement.
Summary of the invention
The deficiency existing for prior art, the flow control system that the object of the present invention is to provide a kind of protection against erosion to wear and tear.
For achieving the above object, the invention provides following technological scheme: a kind of flow control system of protection against erosion wearing and tearing, comprise main line and be arranged on the cue ball valve on main line, also comprise looped pipeline road, the two ends on described looped pipeline road respectively with the suction side of main line, outlet side is connected, the Flow area on described looped pipeline road is less than the Flow area of described main line, described looped pipeline is provided with auxiliary-valve and current-limiting mechanism on road, described current-limiting mechanism is arranged on the suction side position of the corresponding main line of auxiliary-valve, described current-limiting mechanism comprises the metering hole in the runner that is placed in looped pipeline road, the area of described metering hole is less than the Flow area on described looped pipeline road.
