Description
Technical Field
The utility model belongs to the technical field of the water supply system technique and specifically relates to a supply channel choke valve aperture indicating device.
Background
At present, the throttle valve body has no opening indication, the opening of the throttle valve is reflected through a flowmeter on a water supply pipeline, but if the water flow is low, whether the throttle valve is caused by the opening change of the throttle valve or the flow caused by other reasons cannot be immediately and accurately judged.
Disclosure of Invention
An object of the utility model is to solve the not enough of prior art, provide a simple structure, look over convenient supply channel choke valve aperture indicating device.
The utility model provides a technical scheme that its technical problem adopted is:
the utility model provides a supply channel choke valve aperture indicating device, includes the valve body, its characterized in that be equipped with aperture indicating device on the valve body, it includes support and pointer, axial linear array is equipped with aperture scale concave line and aperture spill digitline on the polished rod section on the screw thread section upper portion of the rotation axis of valve body, aperture scale concave line is the annular, and encircles along the rotation axis circumference, the support lower extreme is through pin and valve body fixed connection, upper end one side and the perpendicular fixed connection of pointer, the pointer needle point is relative with the rotation axis, through the aperture scale concave line and the aperture spill digitline that the pointer corresponds, can know the aperture of valve body.
Pointer and support adopt the wire to buckle and form, the round ring is sold to the round ring to the support lower extreme and is passed the round ring and fix the ring on the valve body.
The utility model discloses owing to adopt above-mentioned structure, have simple structure, look over advantages such as convenient.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Reference numerals: the valve comprises a valve body 1, a support 7, a pointer 8, an opening degree scale concave line 9, a rotating shaft 10 and an opening degree concave digital line 11.
Detailed Description
The present invention will be described with reference to the accompanying drawings and examples.
As shown in the attached drawing, the opening indicating device of the water supply pipeline throttle valve comprises a valve body 1 and is characterized in that the valve body 1 is provided with an opening indicating device which comprises a support 7 and a pointer 8, an opening scale concave line 9 and an opening concave digital line 11 are arranged on a polished rod section on the upper part of a thread section of a rotating shaft 10 of the valve body in an axial linear array, the opening scale concave line 9 is annular and surrounds along the circumference of the rotating shaft 10, the lower end of the support 7 is fixedly connected with the valve body 1 through a pin, one side of the upper end of the support is vertically and fixedly connected with the pointer 8, the needle point of the pointer 8 is opposite to the rotating shaft 10, and the opening of the valve body can be known through the opening scale concave line and the opening concave digital line corresponding to the pointer 8, the opening concave digital line of the opening of the valve body is sequentially 0 degree, 30 degrees, 60 degrees and 90 degrees from bottom to top, 0, 90 ° indicates a fully open state.
Pointer and support adopt the wire to buckle and form, the round ring is sold to the round ring to the support lower extreme and is passed the round ring and fix the ring on the valve body.
The utility model discloses in the use, the hand wheel of rotatory choke valve, choke valve are under initial condition, and the pointer corresponds 0, and operating personnel is as required flow, and when opening the choke valve 30 or 60, the choke valve is rotatory to be moved down for the pointer aim at 30 or 60 aperture scale concave curve can.
If the opening size and the flow of the throttle valve are required to be known, the opening concave digital lines corresponding to the opening scale concave lines on the rotating shaft after the rotating shaft corresponding to the pointer rotates can be quickly known only by looking up the opening concave digital lines.
The utility model discloses owing to adopt above-mentioned structure, have simple structure, look over advantages such as convenient.
Claims (2)
