Abstract
The invention aims at providing a valve capable of controlling opening accurately. The valve comprises a valve body, wherein a water inlet and a water outlet are formed in the valve body. The valve body is provided with a valve core, wherein one end of the valve core is arranged in the valve body and the other end of the valve core stretches out of the valve body. The valve core can open or close the valve through rotation. A guiding groove is formed in the outer wall of the valve body. An indicating rod is installed in the guiding groove and the side of the guiding groove is installed with marks. The rod body of the indicating rod and the valve core are provided with grinding teeth, wherein the grinding teeth are matched so that rotation of the indicating rod is converted into linear movement in the guiding groove in the guiding groove. In the process of rotating the valve core to open the valve, the rotation of the valve core is concerted into the linear movement of the indicting rod in the guiding groove due to the fact that rod body of the indicating rod and the valve core are provided with the grinding teeth, wherein the grinding teeth are matched. The moving distance of the indicting rod in the guiding groove is in direct proportion to the rotating degree of the valve core. Therefore, the rotating degree of the valve core is obtained by only measuring moving distance of the indicting rod with the reference of the marks. Accordingly, the opening of the valve is controlled accurately.
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 fluid delivery system, has cut-off, adjusting, water conservancy diversion, prevents the functions such as adverse current, voltage stabilizing, shunting or overflow pressure relief.The valve that is used for liquid control system, from the simplest stop valve to very complicated robot control system(RCS) various valves used, 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 to accurately control the aperture of valve, and existing valve is all to control by the operator is subjective, therefore the not corresponding reference of controlling aperture can 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 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 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, so that the rotation of spool changes into the traveling priority 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 is provided with the grinding tooth of working in coordination, therefore the rotation of spool can change into the traveling priority of indicating arm in guiding groove, the displacement distance of indicating arm in guiding groove is directly proportional to the angle of valve core rotation, therefore as long as measure with reference to scale the distance that indicating arm moves, 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 until the angle of valve core rotation, and therefore the aperture of control valve accurately, have good practicability.
Description of drawings
Fig. 1 is the structural representation that can accurately control the valve of aperture of the present invention.
Embodiment
The below contrasts accompanying drawing, 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, 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 the 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 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 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, so that the rotation of spool 2 changes into the traveling priority 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 is provided with the grinding tooth 6 of working in coordination, therefore the rotation of spool 2 can change into the traveling priority of indicating arm 4 in guiding groove 3, the displacement distance of indicating arm 4 in guiding groove 3 is directly proportional to the angle that spool 2 rotates, therefore as long as measure with reference to scale 5 distance that indicating arm 4 moves, can know the angle that spool 2 rotates, thus the aperture of accurate control valve.
Claims (1)
1. the valve that can accurately control aperture, comprise the valve body that is provided with water intake, water outlet, and described valve body is provided with an end and is arranged in valve body, and the other end extends the spool of valve body, and described spool is opened or throttle down by rotating; The outer wall that it is characterized in that described valve body is provided with a guiding groove, in 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, so that the rotation of spool changes into the traveling priority of indicating arm in guiding groove.
