Abstract
The utility model discloses a steady flow valve. Steady flow valve including valve body, valve core case, case, forms the exhalant canal between case and the disk seat, the case overcoat is equipped with the spring, and spring one end offsets with the valve core case, and the other end offsets with the case, having seted up water on the fixed plate and having led to the groove, and still be equipped with the regulation pole on the fixed plate, the front end of adjusting the pole is the toper structure to arrange in and go in ring between the boss, and form inhalant canal between the annular boss. The beneficial effects of the utility model are that: when intaking end pressure power grow, the elastic force that movable valve element overcomes the spring can be pushed away and the disk seat is close to, make the exhalant canal diminish, case removal simultaneously can make the inhalant canal grow for the pressure differential of exhalant canal both sides becomes bigger, and according to the relation between discharge, rivers area, the water pressure, the rivers area is inversely proportional to with the evolution of pressure differential, and water pressure changes sooner more greatly than rivers area, further guarantees out the flow stability of water end (W. E. ), and pressure stability plays the stationary flow effect.
Description
Technical field
This utility model is related to a kind of valve, specifically related to a kind of flow stabilizing valve.
Background technology
At present, flow stabilizing valve is widely used in hot-water heating industry, adjusts flow by water flow temperature and ensures leaving water temperature
Reach a stationary value.
Chinese utility model patent application（Shen Qing Publication day：2013.07.24, application publication number：CN103216650A）Public
Drive a kind of flow control valve, including valve body, regulator base, actuator, memory alloy spring, valve seat.Adjust flow valve work
When, when hydraulic pressure increases suddenly, hydraulic pressure can promote actuator to overcome the elastic force of memory alloy spring to move towards valve seat direction, makes
The water space that goes out between actuator and valve seat reduces.
In addition, this flow control valve also add needle, this needle is arranged on valve seat, the tapered tip in its front end
Portion, plays shunting current stabilization effect, makes the regulation process stability of regulating valve more preferably, when hydraulic pressure increases suddenly, actuator and valve
Entering water space and equally can reduce between pin, plays the effect of auxiliary adjustment.
The Main Function of flow stabilizing valve, is when the intake pressure of water inlet end increases it is ensured that the discharge pressure of water side keeps
Inconvenience, according to the relation between discharge, current area, hydraulic pressure, current area is inversely proportional to the evolution of pressure reduction, when above-mentioned flow
When regulating valve water inlet end hydraulic pressure increases suddenly, water inlet end becomes big with the pressure differential of water side, goes out water space（Current area）Diminish,
Thus being adjusted correspondingly to hydraulic pressure, but being the increase in the structure of needle, when pressure becomes big, entering water space and diminishing so that going out
The pressure differential of water space both sides becomes less, and goes out water space（Current area）Determined by the hydraulic pressure of entrance point, therefore, on
State flow control valve and can only play an effect preferably subtracting stream it is difficult to ensure the pressure requirements of water side it is impossible to expire
Sufficient customer demand.
