Description

Water supply pipeline throttle valve

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.

Background

At present, the throttle valve body has no opening indication, and the opening of the throttle valve is reflected by a flowmeter on a water supply pipeline. The opening of the throttle valve is extremely easy to be touched by mistake, so that the opening is changed, and when the water flow is low, whether the flow is low due to the change of the opening of the throttle valve or due to other reasons cannot be accurately judged.

Disclosure of Invention

An object of the utility model is to solve the not enough of prior art, provide a simple structure, avoid the supply channel choke valve of choke valve mistake commentaries on classics.

The utility model provides a technical scheme that its technical problem adopted is:

the utility model provides a supply line choke valve, includes the valve body, be equipped with the hand wheel on the output shaft of valve body upper end, its characterized in that be equipped with rotation-proof device on the hand wheel, it includes prevents changeing cover, spin and buffer spring, hand wheel periphery circumference is equipped with prevents changeing the track, prevent changeing the ways in the hand wheel outside, prevent changeing cover inner wall circumference interval and be equipped with the blind hole, be equipped with buffer spring and spin in the blind hole, the spin under buffer spring's effect with prevent changeing track roll connection, when the outside commentaries on classics cover of preventing of handle on the choke valve is touched, prevent changeing the cover along preventing changeing track circumference rotation under the effect of spin, avoided outside object or people to touch the handle and lead to.

The utility model discloses can 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 round pin axle 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, and the aperture scale concave line and the aperture spill digitline that correspond through the pointer can know the aperture of valve body.

The pointer and the bracket of the utility model are formed by bending metal wires, the lower end of the bracket is wound into a ring and the ring is fixed on the valve body by a pin penetrating through the ring,

the utility model discloses owing to adopt above-mentioned structure, have simple structure, avoid the choke valve to rotate by mistake, look over advantages such as convenient.

Drawings

Fig. 1 is a schematic structural diagram of an embodiment of the present invention.

Fig. 2 is a schematic structural diagram of another embodiment of the present invention.

Reference numerals: the anti-rotation valve comprises a valve body 1, a hand wheel 2, an anti-rotation sleeve 3, a rolling ball 4, a buffer spring 5, an anti-rotation track 6, 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 accompanying drawings, a supply line choke valve, including valve body 1, the structure of valve body is the same with prior art, and this is not repeated, be equipped with annular hand wheel 2 on the output shaft of 1 upper end of valve body, its characterized in that the cover is equipped with rotational lock on the hand wheel 2, and it includes swivel sleeve 3, spin 4 and buffer spring 5, 2 periphery circumference of hand wheel is equipped with prevents changeing track 6, 3 covers in the hand wheel 2 outsidely of swivel sleeve, 3 inner wall circumference intervals of swivel sleeve are equipped with the blind hole, be equipped with buffer spring 5 and spin 4 in the blind hole, spin 4 under buffer spring 5's effect with prevent changeing track roll connection, when the outside swivel sleeve of handle on the choke valve is touched, prevent changeing the cover along preventing changeing track circumference rotation under the effect of spin, avoided outside object or people's handle to touch and lead to the aperture to change.

The utility model discloses can be equipped with aperture indicating device on the valve body, it includes support 7 and pointer 8, axial linear array is equipped with aperture scale concave line 9 and aperture spill digitline 11 in the polished rod section on the screw thread section upper portion of the rotation axis 10 of valve body, aperture scale concave line 9 is the annular, and encircles along rotation axis 10 circumference, 7 lower extremes of support are through round pin axle and 1 fixed connection of valve body, upper end one side and 8 vertical fixed connection of pointer, pointer and support adopt the wire to buckle and form, the wound ring of support lower extreme is sold the nail and is passed the ring and fix the ring on the valve body, 8 needle points of pointer are relative with rotation axis 10, through the aperture scale concave line and the aperture spill digitline that 8 pointers correspond, can know the aperture of valve body, aperture spill digitline is 0, 30 by supreme lower in proper order, 60 °, 90 °, 0 ° represents a fully closed state, 30 ° and 60 ° represent an opening to a certain angle, and 90 ° represents a fully open state.

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 moves down in the rotation of choke valve as required flow, when opening the choke valve 30 or 60 for the pointer aims at 30 or 60 aperture scale concave curve, then, sheathe in anti-rotation device can.

If the anti-rotation sleeve outside the handle on the throttle valve is touched, the anti-rotation sleeve rotates along the anti-rotation track in the circumferential direction under the action of the rolling ball, and the situation that the opening degree is changed due to the fact that an external object or a person touches the handle is avoided.

If the opening size and the flow of the throttle valve are required to be known, the opening size and the flow can be quickly known only by looking up the opening concave digital lines corresponding to the opening scale concave lines on the rotating shaft corresponding to the pointer.
