Detailed Description
In order to make the technical solution of the present invention better understood by those skilled in the art, the following description of the preferred embodiments of the present invention is given with reference to the accompanying examples, but it should be understood that the drawings are for illustrative purposes only and are not to be construed as limiting the patent; for the purpose of better illustrating the embodiments, certain features of the drawings may be omitted, enlarged or reduced, and do not represent the size of an actual product; it will be understood by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted. The positional relationships depicted in the drawings are for illustrative purposes only and are not to be construed as limiting the present patent.
As shown in fig. 1 to 3, a modified structure for solving the valve position display of a pump control valve, the pump control valve comprises a valve plate 1 for cutting off water flow, a valve rod 2 fixedly connected with the valve plate 1, and a valve cover 3 positioned above the valve rod 2, wherein one end of the valve rod 2 close to the valve cover 3 is provided with an extension part 21 extending outwards along the length direction of the valve rod and penetrating through the valve cover 3, and display marks are arranged on the extension part 21.
Further, in another embodiment, in order to better facilitate clear and visual display of the opening degree of the valve plate 1, a scale mark (not shown) is provided along the length direction of the extension portion 21, and the scale mark is marked in mm.
Further, in another embodiment, in order to prevent water leakage from the connection gap between the valve rod 2 and the bonnet 3 during movement, two O-rings 4 are disposed along the length direction of the valve rod 2 at the connection gap between the valve rod 2 and the bonnet 3.
The utility model discloses a theory of operation of an embodiment as follows:
when the pump control valve is opened, the valve plate 1 is gradually changed from a closed state to an opened state under the drive of the valve rod 2, the exposed parts of the valve rod 2 are gradually increased, and the scales of the exposed parts can display the specific opening position of the valve plate 1. On the contrary, when the pump control valve is closed, the valve plate 1 is gradually changed from the open state to the closed state under the driving of the valve rod 2, the exposed part of the valve rod 2 is gradually reduced, and the scale of the exposed part can display the specific closed position of the valve plate 1.
The utility model is based on the typical structure foundation of the original pump control valve, the position of the valve plate 1 can be visually displayed by adding the extension part 21 and setting the scale marks; the valve overflowing channel is not required to be modified, and the feasibility of the scheme is ensured without influencing the performance of the valve.
