Abstract
The utility model relates to a regulating valve, comprising a valve body. A valve rod is arranged in the valve body, one end of the valve rod is fixedly connected with a handle, and the other end of the valve rod is fixedly connected with a movable abrasive wheel on which a throttling orifice is arranged; a static abrasive wheel is fixed on the valve body, a throttling orifice which corresponds to the shape and the position of the throttling orifice of the movable abrasive wheel is arranged on the static abrasive wheel, and the static abrasive wheel and the movable abrasive wheel are mutually abutted. The utility model has the advantages that the operation can be easily and stably, and vibration can not be caused and noise can not be sent out; each time when the valve is opened and closed for once, soil which remains on work sealing surfaces can be thoroughly removed for once, so that the sealing surfaces can be avoided from being damaged by foreign matters which enter between two work sealing surfaces, and accordingly, the service life of the utility model can be extended.
Description
The utility model relates to a kind of modulating valve.
Modulating valve is mainly used in the Flow-rate adjustment of liquid stream on the pressure piping, air-flow, steam flow and ends.Defectives such as the modulating valve of traditional form generally adopts screw thread valve rod lifting structure, and adjusting flow effort is consuming time, and valve seat is easily stifled easily to be blocked, and also exists simultaneously to be not closed completely, and working life is short.
The purpose of this utility model is to overcome the above-mentioned defective of prior art, provide a kind of simple in structure, operation easily fast, the modulating valve of good, the long service life of Flow-rate adjustment.
The utility model comprises the valve body that is provided with import and outlet, be provided with valve rod in the valve body, one end of valve rod stretches out outside valve body affixed with handle, the other end and moving emery wheel are affixed, moving emery wheel is provided with throttle orifice, is installed with quiet emery wheel simultaneously on valve body, and quiet emery wheel is provided with the corresponding throttle orifice of throttle orifice of shaped position and moving emery wheel, quiet emery wheel and moving emery wheel are fitted mutually, and the import of valve body and outlet are located at the both sides of dynamic and static emery wheel respectively.
Because this type modulating valve has designed two emery wheels that respectively have two throttle orifices and has rotated relatively, carry out Flow-rate adjustment by the actual internal area that changes medium, complete shut-down to standard-sized sheet only needs handle half-twist angle just can realize, and this working seal plane to emery wheel is close together all the time, operate easily steadily, will not cause vibrations and make a noise, whenever valve opening and closing once, the dirt that remains on the working seal face can also be removed once up hill and dale, avoided foreign material to enter between the two working seal faces and the damage sealing surface.
Further illustrate particular content of the present utility model below in conjunction with drawings and Examples.
Fig. 1: the structural representation of present embodiment;
Fig. 2: the fundamental diagram of present embodiment two emery wheels under in off position;
Fig. 3: the fundamental diagram of present embodiment two emery wheels under adjustment state;
Fig. 4: the fundamental diagram of present embodiment two emery wheels under full-gear.
As shown in the figure, present embodiment comprises the valve body 1 that is provided with import 2 and outlet 3, be provided with valve rod 4 in the valve body 1, one end of valve rod 4 stretches out outside valve body 1 affixed with handle 5, the other end is affixed by pin and moving emery wheel 6, moving emery wheel 6 is provided with the throttle orifice of two symmetries, on valve body 1, be installed with simultaneously quiet emery wheel 7, quiet emery wheel 7 is provided with the corresponding throttle orifice of throttle orifice of two shaped positions and moving emery wheel 6, the one side of quiet emery wheel 7 fits tightly mutually with the one side of moving emery wheel 6, the import 2 of valve body 1 is located at the another side of moving emery wheel 6, and outlet 3 is located at the another side of quiet emery wheel 7.When valve in off position the time, the throttle orifice of two emery wheels is in vertically position (Fig. 2) in opposite directions, and runner is blocked fully; Make also rotating certain angle thereupon of emery wheel when the handle rotating certain angle and by valve rod, at this moment the relative position of two emery wheels has just formed two crescent shape holes (Fig. 3), fluid is divided into two bursts of tributaries by two crescent shape holes, merges into one outlet port from valve again and flows out; When handle rotates 90 ° when making emery wheel also rotate 90 °, the throttle orifice on the throttle orifice on the moving emery wheel and the quiet emery wheel is complete relative (Fig. 4) just, and at this moment the flow of valve is a maximum.In addition, valve because fluid can produce certain pressure to emery wheel, makes moving emery wheel and quiet emery wheel to be close together all the time at work, and the sealability of working surface is strengthened.
Claims (1)
