Abstract
The utility model discloses a novel adjusting valve, which comprises a valve body, a valve rod, a wrench and a valve core, wherein the valve rod is fixedly connected with the valve core; the valve core and the valve rod are sealed conically, and the lower end of the excircle of the valve core is larger in diameter while the upper end of the excircle of the valve core is smaller; and a strong magnet is arranged at the valve body at the lower end of the valve core. Preferably, a valve body bump is arranged at the upper end of the valve body; the center of the wrench is movably connected with the valve body bump; and one end of the wrench is movably connected with the valve rod. Preferably, the sealing surface of the valve core is provided with a conical sealing ring which corresponds to the conical valve core. The novel adjusting valve has the beneficial effects that the structure is simple; the magnet is designed, so that higher opening and closing speeds of the valve are realized; a conical sealing surface is designed, so that the service life is prolonged greatly, and the sealing effect is more stable; and the novel adjusting valve is suitable for popularizing on a large scale.
Description
Technical field
The utility model belongs to valve field, particularly a kind of novel modulating valve.
Background technique
The tradition modulating valve adopts spiral to open, and opening speed is slow, and the modulating valve sealing surface all adopts burnishing surface sealing or spherical sealing, and its complex structure or sealability are impermanent, and working life is short.
The model utility content
At the deficiencies in the prior art, the utility model provides a kind of modulating valve of good airproof performance long service life simple to operate.
To achieve these goals, technical solution adopted in the utility model is:
A kind of novel modulating valve comprises valve body, valve rod, spanner and spool, and valve rod and spool are affixed, and spool and valve stem seal place are that the big upper end of cone seal and spool outside diameter lower end is little, are positioned at the positive lower end of spool at valve body and are provided with a strong magnets.
As preferably, comprise that also the valve body upper end is provided with the valve body projection, described spanner center and valve body movable connection of projection, spanner one end is connected with valve rod is movable.
As preferably, valve core sealed cover is provided with the conical seal ring corresponding with taper valve core.
The beneficial effects of the utility model: the utility model is simple in structure, and magnet design makes valve opening and closing velocity faster, adopts the conical seal (contact) face design, and strengthen its working life greatly, and sealing effect is more stable, is suitable for large-scale popularization and uses.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
A kind of novel modulating valve as shown in Figure 1, comprise valve body 1, valve rod 3, spanner 5 and spool 2, valve rod 3 is affixed with spool 2, and spool 2 is that the big upper end of cone seal and spool 2 outside diameter lower ends is little with valve rod 3 sealings place, is positioned at spool 2 positive lower ends at valve body 1 and is provided with a strong magnets 4.Comprise that also valve body 1 upper end is provided with valve body projection 6, described spanner 5 centers and valve body 6 movable connections of projection, spanner 5 one ends and 3 movable connections of valve rod.Spool 2 sealing surfaces are provided with the conical seal ring corresponding with taper valve core 7.
Opening valve only needs spanner 5 Tilly lever principle upwards, and spool 2 moves downward, 4 pairs of spools of magnet, 2 generation magnetic attraction, suction is just more big close to must be more, when spool 2 contacted with bottom valve body 1, spool 2 was just inhaled by force in valve body 1 bottom, reaches the effect of Open valve; Throttle down only needs spanner 5 to pressing down valve rod 3 forced belt movable valve plugs 2, spanner 5 is exerted pressure and is moved upward greater than magnet 4 suction spools 2 disengaging valve bodies 1 bottom, seal water intake, because hydraulic pressure produces certain pressure to spool 2 automatically, make spool 2 firmly seal up water intake.
Be the utility model preferred forms more than, those skilled in the art's simple change and replacement all are within the protection domain of the present utility model in related domain.
