Abstract
The utility model provides a valve capable of accurately controlling an opening degree. The valve capable of accurately controlling the opening degree comprises a valve body which is provided with a water inlet and a water outlet, wherein the valve body is provided with a valve element, one end of the valve element is arranged in the valve body, the other end of the valve element extends out of the valve body, the valve element can open or close the valve capable of accurately controlling the opening degree in a rotating mode, a guiding groove is formed in the outer wall of the valve body, an indicating rod is installed in the guiding groove, scales are arranged on the side of the guiding groove, and a rod body of the indicating rod and the valve element are provided with meshed teeth, the meshed teeth of the rod body of the indicating rod are meshed with the meshed teeth of the valve element, so that rotation of the valve element is converted into linear movement of the indicating rod in the guiding groove. In the process of rotating the valve element to open the valve capable of accurately controlling the opening degree, due to the facts that the rod body of the indicating rod and the valve element are provided with the meshed teeth, and the meshed teeth of the rod body of the indicating rod are meshed with the meshed teeth of the valve element, rotation of the valve element can be converted into linear movement of the indicating rod in the guiding groove, the movement distance of the indicating rod in the guiding groove and an angle of rotation of the valve element are in direct proportion, the angle of rotation of the valve element can be obtained only with the need of measuring the movement distance of the indicating rod according to the scales, and the opening degree of the valve capable of accurately controlling the opening degree can be accurately controlled.
Description
Technical field
The invention belongs to valve technology field, specially refer to a kind of valve that can accurately control aperture.
Background technique
Valve is the controlling component in the fluid delivery system, have by, adjusting, water conservancy diversion, prevent functions such as adverse current, voltage stabilizing, shunting or overflow pressure release.The valve that is used for liquid control system, from the simplest stop valve to very complicated robot control system(RCS) used various valves, its kind and specification are quite various.Valve can be used for controlling flowing of all kinds fluids such as air, water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium.In some use occasion, need accurately control the aperture of valve, and existing valve all is to control by the operator is subjective that the reference of not corresponding control aperture can so can't accurately be controlled the aperture of valve.
Summary of the invention
The objective of the invention is to propose a kind of valve that can accurately control aperture.
The valve that can accurately control aperture of the present invention comprises the valve body that is provided with water intake, water outlet, and described valve body is provided with an end and is arranged in the valve body, and the other end extends the spool of valve body, and described spool is opened or throttle down by rotating; Key is that the outer wall of described valve body is provided with a guiding groove, in the described guiding groove indicating arm is installed, and the side of guiding groove is provided with scale; The shaft of described indicating arm and described spool are provided with the grinding tooth of working in coordination, and move so that the rotation of spool changes into the straight line of indicating arm in guiding groove.
In the process of rotational valve core with Open valve, because shaft and the described spool of indicating arm are provided with the grinding tooth of working in coordination, therefore the rotation of spool can change into the straight line of indicating arm in guiding groove and moves, the displacement distance of indicating arm in guiding groove is directly proportional with the angle of valve core rotation, therefore as long as measure the distance that indicating arm moves with reference to scale, can know the angle of valve core rotation, thus the aperture of accurate control valve.
The valve that can accurately control aperture of the present invention is by arranging indicating arm and the corresponding scale that can reflect the valve core rotation angle, can make the operator accurately up to the angle of valve core rotation, and therefore the aperture of control valve accurately has good practicability.
Description of drawings
Fig. 1 is the structural representation that can accurately control the valve of aperture of the present invention.
Embodiment
Contrast accompanying drawing below, by the description to embodiment, the effect of the mutual alignment between the shape of the specific embodiment of the present invention such as related each member, structure, the each several part and annexation, each several part and working principle etc. are described in further detail.
Embodiment 1:
As shown in Figure 1, the valve that can accurately control aperture of present embodiment comprises the valve body 1 that is provided with water intake, water outlet, described valve body 1 is provided with an end and is arranged in the valve body 1, and the other end extends the spool 2 of valve body 1, and described spool 2 is opened or throttle down by rotating; The outer wall of described valve body 1 is provided with a guiding groove 3, in the described guiding groove 3 indicating arm 4 is installed, and the side of guiding groove 4 is provided with scale 5; The shaft of described indicating arm 4 and described spool 2 are provided with the grinding tooth 6 of working in coordination, and move so that the rotation of spool 2 changes into the straight line of indicating arm 4 in guiding groove 3.
In the process of rotational valve core 2 with Open valve, because shaft and the described spool 2 of indicating arm 4 are provided with the grinding tooth 6 of working in coordination, therefore the rotation of spool 2 can change into the straight line of indicating arm 4 in guiding groove 3 and moves, the displacement distance of indicating arm 4 in guiding groove 3 is directly proportional with the angle that spool 2 rotates, therefore as long as measure the distance that indicating arm 4 moves with reference to scale 5, can know the angle that spool 2 rotates, thus the aperture of accurate control valve.
