Abstract
The utility model discloses a regulating valve. The regulating valve comprises a valve body, a valve core and a valve rod; the valve rod and the valve core are fixedly connected; the valve core and the valve body are connected in a sealed mode; conical seal is applied to the seal surface of the valve body and the valve core, and moreover, the lower end of the valve core is smaller than the upper end; the corresponding conical water inlets are formed in the sealing opening of the valve body and the seal surface of the valve core, and the upper end of the water inlet is larger than the lower end. Preferably, the valve core is provided with a conical seal ring corresponding to the seal surface of the valve core. Preferably, the valve body is of a structure molded by cast at one time. The regulating valve provided by the utility model is simple in structure, adopts a conical seal surface design, so that the service life is prolonged greatly; the sealing effect is more stable; the regulating valve is suitable for being popularized and used in a large scale.
Description
Technical field
The utility model belongs to valve field, particularly a kind of modulating valve.
Background technique
Tradition modulating valve sealing surface all adopts burnishing surface sealing or spherical sealed, and its complex structure or sealability are impermanent, and working life is short.
Model utility content
For the deficiencies in the prior art, the utility model provides a kind of modulating valve of good airproof performance long service life.
To achieve these goals, technical solution adopted in the utility model is:
A kind of modulating valve, comprise valve body, spool and valve rod, valve rod and spool are affixed, spool is connected with valve seal, and valve body and valve core sealed cover adopt cone seal, and spool lower end is little, upper end is large, valve seal mouth is corresponding with valve core sealed cover is provided with taper water intake, and great ， lower end, water intake upper end is little.
As preferably, described spool is provided with the conical seal ring corresponding with valve core sealed cover.
As preferably, described valve body casting once-through structure.
The beneficial effects of the utility model: the utility model is simple in structure, adopt conical seal (contact) face design, and greatly strengthen its working life, and sealing effect is more stable, are suitable for large-scale popularization and use.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
A kind of modulating valve as shown in Figure 1, comprise valve body 1, spool 3 and valve rod 2, valve rod 2 and spool 3 are affixed, spool 3 is tightly connected with valve body 1, and valve body 1 adopts cone seal with spool 3 sealing surfaces, and spool 3 lower ends are little, upper end is large, valve body 1 sealed mouth is provided with taper water intake with spool 3 sealing surfaces are corresponding, and great ， lower end, water intake upper end is little.Described spool 3 is provided with the conical seal ring 4 corresponding with spool 3 sealing surfaces.Described valve body 1 casting once-through structure.
