Description
Technical field
The present invention relates to water system technical field, specifically a kind of water supply pipe throttle valve.
Background technique
Throttle body is indicated without aperture at present, and the aperture of throttle valve is reflected by the flowmeter on water supply pipe.Section
Whether the aperture of stream valve is easily accidentally touched, and aperture is caused to change, occur being unable to judge accurately when water flow is low due to throttling
Valve opening variation causes flow caused by still other reasons low.
Summary of the invention
It is an object of the invention to solve the deficiencies in the prior art, provide that a kind of structure is simple, throttle valve is avoided to misroute
Water supply pipe throttle valve.
The technical solution adopted by the present invention to solve the technical problems is:
The output shaft of a kind of water supply pipe throttle valve, including valve body, the valve body upper end is equipped with handwheel, it is characterised in that described
Handwheel is equipped with anti-rotation device comprising and rotating prevention sleeve, spin and buffer spring, the handwheel periphery are circumferentially with anti-rotation track,
The rotating prevention sleeve covers outside handwheel, and the rotating prevention sleeve inner wall circle spacing is equipped with blind hole, is equipped with buffer spring in the blind hole
And spin, the spin are rolled with anti-rotation track under the action of buffer spring and are connected, when preventing for the handle outer on throttle valve
When pivoted housing is touched, rotating prevention sleeve rotates in a circumferential direction under the action of spin along anti-rotation track, avoids exterior object or people opponent
Handle is touched and aperture is caused to change.
The present invention can be equipped with opening indicator device on the valve body comprising bracket and pointer, the rotation of the valve body
Axial linear array is equipped with aperture scale concave and aperture spill digital line on axis, the aperture scale concave in a ring, and edge
Rotary shaft circumferential ring is around the pedestal lower end is fixedly connected with the valve body, and upper end side is fixedly connected with pointer, the pointer needle point
It is opposite with rotary shaft, by the corresponding aperture scale concave of pointer and aperture spill digital line, that is, it may know that the aperture of valve body.
In use, if the rotating prevention sleeve of the handle outer on throttle valve is touched, rotating prevention sleeve is in spin by the present invention
Under the action of rotate in a circumferential direction along anti-rotation track, avoid exterior object or people touch handle and aperture is caused to become
Change；If it is to be understood that the opening size and flow of throttle valve, need to only check the scale concave side in the corresponding rotary shaft of pointer
Aperture spill digital line.
The present invention is due to using the above structure, having many advantages, such as that structure is simple, throttle valve is avoided to misroute.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Appended drawing reference: valve body 1, rotating prevention sleeve 3, spin 4, buffer spring 5, anti-rotation track 6, bracket 7, pointer 8, is opened handwheel 2
Spend scale concave 9, rotary shaft 10, aperture spill digital line 11.
Specific embodiment
The present invention will be described with reference to the accompanying drawings and examples.
As shown in the picture, a kind of water supply pipe throttle valve, including valve body 1, the structure of the valve body is same as the prior art,
This is not repeated, and the output shaft of 1 upper end of valve body is equipped with handwheel 2, it is characterised in that and the handwheel 2 is equipped with anti-rotation device,
It includes rotating prevention sleeve 3, spin 4 and buffer spring 5, and 2 periphery of handwheel is circumferentially with anti-rotation track 6, and 3 sets of the rotating prevention sleeve exists
Outside handwheel 2, the 3 inner wall circle spacing of rotating prevention sleeve is equipped with blind hole, and buffer spring 5 and spin 4 are equipped in the blind hole, described
Spin 4 is rolled with anti-rotation track under the action of buffer spring 5 and is connected, when the rotating prevention sleeve of the handle outer on throttle valve is touched
When, rotating prevention sleeve rotates in a circumferential direction under the action of spin along anti-rotation track, avoids exterior object or people touches handle
And aperture is caused to change.
The present invention can be equipped with opening indicator device on the valve body comprising bracket 7 and pointer 8, the rotation of the valve body
Axial linear array is equipped with aperture scale concave 9 and aperture spill digital line 11 in shaft 10, and the aperture scale concave 9 is in ring
Shape, and along 10 circumferential ring of rotary shaft around, 7 lower end of bracket is fixedly connected with valve body 1, and upper end side is fixedly connected with pointer 8,
8 needle point of pointer and rotary shaft 10 are opposite, pass through the corresponding aperture scale concave of pointer 8 and aperture spill digital line
Know the aperture of valve body.
In use, if the rotating prevention sleeve of the handle outer on throttle valve is touched, rotating prevention sleeve is in spin by the present invention
Under the action of rotate in a circumferential direction along anti-rotation track, avoid exterior object or people touch handle and aperture is caused to become
Change；If it is to be understood that the opening size and flow of throttle valve, need to only check the scale concave side in the corresponding rotary shaft of pointer
Aperture spill digital line can quickly learn flow.
The present invention is due to using the above structure, having many advantages, such as that structure is simple, throttle valve is avoided to misroute.
