Abstract
A ball valve can be widely used as the ball valve can be opened and closed conveniently and has small fluid resistance. But the small size ball valve is easy to be operated falsely owing to convenient opening and closing, thus giving rise to serious results on some occasions. The invention provides an anti-faulty action ball valve handle which comprises a valve handle (1), a pin (2) and a magnetic seat (3), is marked with warning colors and has compact structure, rapid operation, simple principle and low cost.
Description
Affiliated technical field
The present invention relates to a kind of ball valve handle, especially be with the false action-proof function, can be widely used in the ball valve handle of producing and living.
Background technique
Ball valve is widely used because of switch is convenient rapidly, fluid resistance is little.But just because of switch is convenient, small-sized ball valve is easy to by misoperation, can lead to grave consequences in some occasion.Common false action-proof method is to lay down ball valve handle or tie ball valve handle at present, prevents action.Though correlation technique produces effect, in the time of going to adjust the ball valve flow, can not find valve handle or lose time because of removing binding.
Summary of the invention
The purpose of this invention is to provide a kind of false action-proof ball valve handle, its compact structure, swift to operate, principle is simple, with low cost, satisfactory for result.
The present invention realizes by following steps: change the valve handle state for not influencing switch, valve handle (1) is designed to " 7 " font, and on the corner beat pinhole, valve handle (1) is that symmetry has square opening in " 7 " font corner with the valve handle center line, allows valve handle (1) to rotate around pin (2).With pin (2) ball valve bar and valve handle (1) are put on assembling.What keep valve handle (1) does not influence on off state, is mounted with a magnetic base (3) on valve body, and magnetic force can hold ball valve handle (1).
The invention has the beneficial effects as follows, compact structure, swift to operate, principle is simple, with low cost, the improvement of existing valve is also realized quite easily.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the front view of valve handle (1).
Fig. 2 is the plan view of valve handle (1).
Fig. 3 is the left view of valve handle (1).
Fig. 4 is the schematic representation of the present invention when adjusting flow.
Schematic representation during Fig. 5 false action-proof that is the present invention after adjusting flow.
Among Fig. 4: 1, valve handle 2, pin 3, magnetic base 4, ball valve body
Embodiment
As can be seen from Figure 4, false action-proof ball valve handle is made up of with magnetic base (3) valve handle (1), pin (2).Valve handle (1) is " 7 " font, and magnetic conductive material can be held by magnetic base.Valve handle (1) is drilled with pinhole at " 7 " font corner end face, and pin (2) can be installed, and valve handle (1) appearance has caution red.
As can be seen, valve handle (1) is that symmetry has square opening in " 7 " font corner with the valve handle center line from Fig. 4 and Fig. 5, allows valve handle (1) to rotate around pin (2).
As can be seen from Figure 1, pin (2) agency part is cylindrical, and valve handle (1) is connected with valve rod.
As can be seen from Figure 4, magnetic base (3) is a neodymium-iron-boron magnetic material, is installed on the valve body.Magnetic force can hold valve handle (1) and keep plumbness.
The reset condition of valve handle (1) is and the pipeline level will regulate flow now, and will prevent misoperation.According to traffic requirement, valve handle (1) is adjusted to several angle, then valve handle (1) up to be lifted, valve handle (1) turns to vertical with pipeline around pin (2), and magnetic base this moment (3) holds valve handle (1) and keeps this state.This moment, all angles can the convection current volume production not given birth to influence, reach the false action-proof purpose as running into valve handle (1) because of carelessness.
The reset condition of valve handle (1) is vertical with pipeline, will regulate flow now, and will prevent misoperation.At first with the state of valve handle (1) from the vertical level that is adjusted to pipeline, regulate flow by traffic requirement again.Then valve handle (1) is up lifted, valve handle (1) turns to vertical with pipeline around pin (2), and magnetic base this moment (3) holds valve handle (1) and keeps this state.This moment, all angles can the convection current volume production not given birth to influence, reach the false action-proof purpose as running into valve handle (1) because of carelessness.
Go up significantly red caution look from the ball valve limit through out-of-date discovery valve handle (1), keep at a distance with it, prevent misoperation.
Claims (6)
