Abstract
The utility model relates to a flow valve capable of controlling flow by rotational speed. The flow valve can control a door sheet to open and close a flow channel through the cam rotations which act on a guide rod and the door sheet, and the flow can be controlled by the opening and closing frequencies of the door sheet due to different rotational speeds. The flow valve is composed of a valve body, a flow channel, a cam, a guide rod, a door sheet, etc. The flow valve has the advantages of easy fabrication and reliable use.
Description
The utility model relates to a kind of Flow valve, particularly a kind of Flow valve by the rotating speed control flow rate.
Various types of Flow valves are arranged at present, majority all is that the switching degree of one-tenth with control valve comes control flow rate, and this Flow valve itself is simple, but its control gear is then comparatively numerous and diverse, the Flow valve that relates in the supply for flow dynamics control or motor fuel particularly, practicality gets up to have very big difficulty.
The purpose of this utility model is to provide a kind of Flow valve by the rotating speed control flow rate, makes the control of flow oversimplify, and is suitable for reliable.
Principle of the present utility model is: according to flow Q=SV(Q is flow, S is a cross-sectional area, V is a flow velocity) when valve and different frequency open and close, then be in the speed V=at=f/mt of any particle at valve place, and only when valve opening particle just be subjected to the effect of separate room power.So the frequency of valve opening and closing is high more, action time is short more, and mean velocity is also more little, and then flow is also more little.
According to above-mentioned principle the utility model by valve body (1) valve body upper outlet joint (2), inlet attack (3) on cover plate (10) and the cover plate, be provided with garden post cavity (a 4) cavity diameter greater than runner (5) diameter on the runner (5) between the inlet of valve body (1) and the outlet, in cavity (4), be provided with one less than cavity (4) diameter greater than runner (5) diameter the door sheet (6), one end face center of door sheet connects guide rod (7), guide rod is arranged in the slideway concentric with runner (8), the other end and the guide rod of guide rod (7) are axially in an acute angle, constitute the inclined-plane, other is provided with the cam (9) that contacts with the inclined-plane, and cam rotating band action-oriented bar and door sheet are done straight line motion; In that being housed on the other end of door sheet, a spring (11) make a sheet under free state, be in the state of closing runner (5).
Advantage of the present utility model is that control flow rate is simple and compact for structure dynamically, reliable operation.
Accompanying drawing is the utility model cross-sectional view;
The utility model can be realized by following examples, but be not limited to embodiment.
Comprise outlet by injection molding, runner, slideway, cavity is at interior valve body, in slideway, be lined with high-abrasive material, the cover plate that can be tightly connected with the screw pressing with valve body that comprises inlet attack with injection molding, door sheet and guide rod are made of metal, make cam according to the flow control scope, promptly constitute Flow valve according to the accompanying drawing assembling.
Claims (2)
1, it comprises valve body (1) a kind of Flow valve by rotating speed control, outlet connection (2) on the valve body (1), inlet attack (3) on cover plate (10) and the cover plate, it is characterized in that: be provided with a garden post cavity (4) greater than runner (5) diameter in the runner (5) between valve body (1) upper outlet joint (2) and cover plate (10) inlet attack (3), in cavity (4), be provided with one less than cavity (4) diameter greater than runner (5) diameter the door sheet (6), one end center of door sheet connects guide rod (7), guide rod (7) is arranged in the slideway concentric with runner (8), guide rod (7) other end contacts with cam (9), is provided with spring (11) between the other end of door sheet (6) and the cover plate (10).
2, a kind of Flow valve by rotating speed control according to claim 1 is characterized in that guide rod (7) contacts inclined-plane of end face with cam (9).
