Abstract

The utility model relates to a magnetic control water valve which is composed of a valve body, a piston bush, a magnetic loop, a magnetic loop sleeve, a handle, a handle cover, a magnetic column, an upper rubber pad, a small piston, a middle rubber pad, a big piston, a lower rubber pad, a check ring, a plastic ring and a steel ball, wherein, the piston bush is connected with the valve body; the magnetic loop, the magnetic loop sleeve, the handle and the handle cover are respectively outward sheathed or connected with the piston bush in sequence; the magnetic column is inward connected with the piston bush; the upper rubber pad is sheathed in the small piston and connected with the bottom of the magnetic column; the middle rubber pad is sheathed in the big piston and is abutted with the bottom of the small piston; the lower rubber pad is sheathed outside the big piston; the check ring is positioned between the piston bush and the handle; the plastic ring is inlaid outside the piston bush and presses against the check ring; the steel ball is positioned between the magnetic column and the piston bush. The rubber pads and the pistons are all hollow, and the bore central lines of the rubber pads and the pistons are coincident with the central lines of water pores on the valve body.

Description

Magnetic control valve

A kind of magnetic control water valve belongs to water valve manufacturing technology field.

Magnetic control water valve comprises valve body, piston, magnetic element and corresponding auxiliary.Generally speaking, can't in its fast opening and closing, have the adjustable function of output flow again concurrently.

But the purpose of this utility model is to provide a kind of not only fast opening and closing but also has the magnetic control water valve of output flow adjustable function concurrently.

Of the present utility model being characterised in that: it is by valve body 1, the piston sleeve 2 that is threaded with it, the magnetic post 3 that is positioned at this cover and cooperates with its inwall, be arranged in the steel ball 4 in the space at this magnetic post 3 and piston sleeve 2 tops, withstand on the last rubber cushion 5 under magnetic post 3 bottom surfaces, cooperate with the inwall of piston sleeve 2 and tightly be enclosed within the outer small piston 6 of rubber cushion 5, withstand on the middle rubber cushion 7 of small piston 6 bottoms, cooperate its bottom big piston 8 outside the rubber cushion 7 and in tightly being enclosed within again over against the water passage hole of valve body 1 with the inwall of piston sleeve 2, tightly be placed in the following rubber cushion 9 of these big piston 8 bottoms, the magnet ring 10 that cooperates with piston sleeve 2 side keys, with these magnet ring 10 friction tight magnet ring covers 11, with these magnet ring cover 11 handles that are threaded 12, the handle cover 13 bonding with its top end, back-up ring 14 between piston sleeve 2 and handle 12 and the plastic ring 15 that is nested in piston sleeve 2 tops and pushes down back-up ring 14 constitute.Wherein, last rubber cushion 5, small piston 6, middle rubber cushion 7, big piston 8, rubber cushion 9 all is a hollow down, their centerline hole all with valve body 1 on the center line of water passage hole coincide.Fig. 1 is asked for an interview in its longitudinal section, and its arrow is represented water (flow) direction.

Use proof: but not only fast opening and closing but also its output flow are also adjustable for this water valve.

In order in conjunction with the embodiments the utility model to be done detailed description below, show as follows employed accompanying drawing number of present specification and title brief introduction:

The longitudinal section of this magnetic control water valve of Fig. 1.

Embodiment:

Ask for an interview Fig. 1.Handle 12 can drive magnet ring cover 11, magnet ring 10 moves up and down apace along the outer wall of piston sleeve 2, thereby driving magnetic post 3 moves up and down big piston 8 by above-mentioned upward rubber cushion 5, small piston 6, middle rubber cushion 7, realized the function of fast opening and closing, also above-mentioned each parts of rotatable handles 12 drives move up and down, the aperture of coming the water passage hole of regulation valve body 1 by the conical lower section of big piston 8 is to realize the adjusting of output flow.Wherein, steel ball 4 has played the effect of avoiding magnetic post 3 tops direct and piston sleeve 2 directly to collide.

Use proof: this magnetic control water valve can be realized expectation function.
