Abstract
The invention discloses a kind of ball seal leg for debating other open/close states, including the rotary type handle (1) with cap, valve body (2), the valve body (2) extends vertically upwards the pole for being provided with that end is circle (3) from nearly cap, the handle (1) is extended vertically downward has end to connect the pole of bead (4), when the ball valve is closed, the collar aperture of the circle (3) happens to allow the bead (4) to fill.Whether the collar aperture by means of the circle (3) allows the bead (4) to fill, and intuitively debates the closure or opening of other ball valve, it helps tactilely-perceptible of the people with visual impairment with finger.
Description
Technical field
The invention belongs to valve, more specifically to a kind of ball seal leg for debating other open/close states.
Background technology
Existing ball seal leg or abbreviation ball valve, it is standard-sized sheet state when handle position overlaps with drain pipe that some are, some
Then for standard-sized sheet state, not unify mutually when handle position and drain pipe are at a right angle, also, although many people often with,
Once asking them the handle position of open and-shut mode, but it is unable to explain clearly.And ball valve is often required that in real life or production, with opening and closing
When the upstream of state-indicating function, such as logistics system surprisingly stops conveying, downstream can't see liquid and flowed out, in standard-sized sheet state
Ball valve, easily is mistaken for being being closed, so that the pass is not related to, once, conveying is recovered in upstream, often wastes material or hair
Raw security incident.
Therefore it provides a kind of ball seal leg for debating other open/close states, tool is of great significance.
The content of the invention
It is an object of the invention to provide a kind of ball seal leg for debating other open/close states.
A kind of ball seal leg for debating other open/close states of the present invention, including the rotary type handle with cap, valve body are described
Valve body extends vertically upwards the pole for being provided with that end is circle from nearly cap, and the handle is extended vertically downward end
End connects the pole of bead, and when the ball valve is closed, the collar aperture of the circle happens to allow the bead to fill.
The method have the advantages that:
Whether the collar aperture by means of the circle allows the bead to fill, and intuitively debates the closure or opening of other ball valve,
Contribute to people with visual impairment with the tactilely-perceptible of finger.
Brief description of the drawings
Fig. 1 is that a kind of ball seal leg for debating other open/close states of the present invention is in the side structure schematic view for closing state.
Fig. 2 is that a kind of ball seal leg for debating other open/close states of the present invention is illustrated in bowing for state is closed to perspective structure
Figure.
Fig. 3 is that a kind of present invention ball seal leg for debating other open/close states bowing in standard-sized sheet state is illustrated to perspective structure
Figure.
Fig. 4 is another embodiment of the present invention ball valve bowing to perspective structure schematic diagram in standard-sized sheet state.
Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.
Shown in Fig. 1 or Fig. 2, Fig. 3, a kind of ball seal leg for debating other open/close states, including the rotary type handle with cap
1, valve body 2, the valve body 2 extends vertically upwards the pole for being provided with that end is circle 3 from nearly cap, and the handle 1 hangs down
The pole that end connects bead 4 directly is extended downward with, when the ball valve is closed, the collar aperture of the circle 3 is happened to
The bead 4 is allowed to fill.The collar aperture internal diameter of the circle 3 and the external diameter of the bead 4 are consistent, generally 8-12 millimeters.
Shown in Fig. 1, Fig. 2, Fig. 3, be suitable for when the position of the handle 1 is at a right angle with the drain pipe of the valve body 2 be
The ball valve of standard-sized sheet state.
Fig. 4 is suitable for when the position of the handle 1 coincides with the drain pipe of the valve body 2 being the ball valve of standard-sized sheet state.
Claims (1)
1. a kind of ball seal leg for debating other open/close states, including the rotary type handle (1) with cap, valve body (2), its feature
It is that the valve body (2) extends vertically upwards the pole for being provided with that end is circle (3) from nearly cap, the handle (1) is hung down
The pole that end connects bead (4) directly is extended downward with, when the ball valve is closed, the collar aperture of the circle (3)
The bead (4) is allowed to fill just at the right time.
