Abstract
The utility model relates to a precise rotary adjusting valve that comprises an angular travel electric executing mechanism, a valve body, a valve cover, an adjusting rod, a valve seat and a valve flap, wherein the upper end of the valve body is fixedly provided with the valve cover; the angle travel electric executing mechanism is connected with the valve flap by the adjusting rod; and the valve seat is fixed in an internal passage of the valve body. According to the change of the practical working condition, the relative motion of two rotary porous plates is adjusted to change a circulating area, thus finally playing the role of adjusting pressure and flow. The precise rotary adjusting valve has a simple structure, can run reliably, and has strong adjusting capability and high durability.
Description
Technical field
It is flow or pressure regulating systems such as steam, water that the utility model relates to medium.Be specifically related to be applied to the rotating regulation valve that thermoelectricity, light textile, oil, chemical industry, papermaking, printing and dyeing etc. need be carried out flow or pressure controlled precision to steam, water etc.
Background technique
Shortcomings such as existing flow or pressure regulator valve generally adopt screw thread valve rod lifting structure, regulate the flow time and effort consuming, and the easily stifled easily card of valve seat is not closed completely, and working life is short.For a long time because medium temperature, pressure, the influence of washing away are difficult to the accurate control that keeps valve for a long time.Therefore need a kind of flow of research and development or pressure regulator valve to use for a long time, leakage rate is little, and does not influence performance.
Summary of the invention
In order to overcome above-mentioned deficiency, the purpose of this utility model is the rotating regulation valve of a kind of precision of design.
To achieve these goals, the utility model is by the following technical solutions:
Valve seat, the flap of accurate rotating regulation valve design do relative motion, by changing the actual internal area of medium, carrying out flow or pressure regulates, completely open and close only needs 90 ° of rotations, and the working seal plane of valve seat, flap is close to together all the time, it is easily quick to operate, and can not send vibrations and noise, and has reduced the erosion damage of sealing surface.Whenever valve closing once can also be removed impurity between valve seat, the flap, avoid damaging sealing surface.Because two rotation orifice plates can reach zero leakage through precise finish up and down.
Accurate rotating regulation valve, it comprises part-turn electric actuator, valve body, valve gap, adjustable lever, valve seat, flap, and the valve body upper end is valve gap fixedly, and part-turn electric actuator connects flap by adjustable lever, and valve seat is fixed on the valve body internal channel.The relative movement of regulating two rotation orifice plates according to the variation of actual conditions changes circulation area, finally plays the effect of regulating pressure, flow.
Accurate rotating regulation valve working principle is: medium is in vertically opposite position by the throttle orifices on the two rotation orifice plates in the valve inlet end inflow valve body, and runner is blocked fully, and valve is in closed condition.When the rotation of the rotation orifice plate that is connected with valve rod, the throttle orifice on the rotation orifice plate partially overlaps, and runner section is opened, and valve is in throttle, continues to rotate to throttle orifice on the two rotation orifice plates when entirely on the center, the whole turn-on flow rate maximums of valve.
Accurate rotating regulation valve simple in structure reliable, regulating power is strong, serviceability is high.
