Abstract
The utility model relates to a spiral-flow energy-dissipation pressure regulating valve. A valve rod is arranged in a valve body, a piston barrel is connected onto the valve rod, and the water feed end and the water discharge end on the valve body form 90 degrees and connected with an inlet guide pipe and an outlet energy dissipater respectively. By means of the pressure regulating valve, energy of water flow entering the valve body can be dissipated, so that the water flow can be discharged from the water discharge end of the valve body after energy dissipation, the pressure of pressure pipelines is reduced greatly, safety of a hydropower station is protected, the structure is compact, and opening and closing actions of the valve are convenient and accurate.
Description
Technical field
The utility model relates to pressure regulator valve.
Background technique
In hydroelectric station operation, when water wheels unit cut when generating under abnormal condition, the stator of water turbine can quick closedown and easily cause the resonance damage water wheels unit of generator set, simultaneously, pressure piping rising water pressure and water power plant water inlet easily occurs destroy by rush of water causes the heavy losses of life and property.In order to guarantee the safety in water power plant, usually select surge shaft and pressure regulator valve to control the rotating speed of water turbine, reduce the hydraulic pressure of pressure piping.But the duration that investment that need to be larger is set and grows of surge shaft, and some power station is limited to landform, geological condition, is difficult to build surge shaft.Although its pressure regulator valve can be reduced investment outlay and the duration than surge shaft, respectively there are a feed-water end and a waterexit end in the both sides that on its structure are pressure regulator valve, after the pressure piping current enter from the feed-water end of pressure regulator valve, directly flow out from the waterexit end of pressure regulator valve, can not eliminate the energy of current, thereby valve and the pipeline in easy impact failure downstream, and volume is large, the occupation of land space is large, manufacture cost is high.
Summary of the invention
The purpose of this utility model is to provide eddy flow energy dissipating pressure regulator valve, and it is a kind of valve that can eliminate the energy of current in valve body.
The technical solution of the utility model is:
The utility model comprises valve body, valve rod, piston cylinder, inducer, energy dissipation below spillway device, a valve rod is arranged in valve body, piston cylinder is on valve rod, inducer is on the feed-water end of valve body, the energy dissipation below spillway device is on the waterexit end of valve body, 90 ° each other of the feed-water end of described valve body and the waterexit ends of valve body are connected with an inducer on the feed-water end of valve body, the waterexit end of valve body is connected with an energy dissipation below spillway device.
Advantage of the present utility model is as follows: the utility model due to feed-water end and waterexit end each other 90 ° and inducer has been installed respectively and the energy dissipation below spillway device after, current are flowed into discharges from the waterexit end after feed-water end enters the valve pocket energy dissipating under backward, reduced greatly the pressure of pressure piping, guaranteed the safety in water power plant, its compact structure, volume are little, and valve opening or closing motion are convenient, accurate.
