Abstract
The utility model discloses a rotatory valve tower structure for carrying low pressure fluid, including stator body, still including the axle with circlip, bearing, rotary seal spare, rotor and set screw, stator body's material is polytetrafluoroethylene, a class slot is joined in marriage to last having seted up of stator body, stator body passes through set screw fixes on rotary platform, bearing quantity is two, inlays respectively and locates stator body's upper end and lower extreme, the axle uses circlip quantity to be two, and it inlays locates just be located in the stator body the bearing outside, the material of rotary seal spare is rubber, quantity for three and distribute in between two bearings, the material of rotor is the stainless steel, and is located in the middle of the stator body. Beneficial effect: in the injection moulding trade, when utilizing the mould of this structure on for rotary platform to carry low pressure cooling water and heated mold's hot water or heat oily, sealing performance is good, and life improves greatly.
Description
Technical field
This utility model relates to injection molding technology field, particularly relates to a kind of rotary return tower structure for carrying low-pressure fluid.
Background technology
Rotary return tower structure is typically to divide water, flow distribution apparatus, is widely used in the fluid conveying of multistation plant equipment.For different fluid pressure condition, use different rotatory sealing.In injection mo(u)lding industry, often using this structure is that the mould conveying low pressure on rotation platform cools down water and the hot water of heating mould or deep fat.Rotary speed is usually no more than 100r/min, belongs to low speed rotation occasion.
Reason due to following: when (1) sealing member is by the pressure effect of working media, self can deform upon, contact force between sealing member and sealed groove becomes big, thus effectively close the gap between coupled face, but hydraulic pressure is usually no more than 5bar, at this pressure, the self-deformation amount of sealing member is limited, and sealability declines；(2) the problems referred to above can solve by improving sealing member compression ratio in sealed groove and pack completeness, but owing to water cannot provide lubrication for sealing member, between sealing member and seal groove, " dry friction " occurs, and sealing part abrasion accelerates, and the life-span is substantially reduced；(3) domestic water quality is also a big problem, after machine uses a period of time, has a large amount of incrustation scale and is attached in seal groove, if machine disables a period of time, incrustation scale can be dry and hard, causes sealing member Focal adhesions, after being again started up, sealing member easily stretcher strain causes damage, and then leakage.So existing rotary return tower structure sealing property is bad.
Utility model content
In view of the foregoing, this utility model provides the rotary return tower structure for carrying low-pressure fluid of a kind of good seal performance, length in service life.
For reaching above-mentioned purpose, this utility model solves its technical problem and be the technical scheme is that
A kind of rotary return tower structure for carrying low-pressure fluid, including stator body, also includes circlip for shaft, bearing, rotating seal, rotor and fixing screw；The material of described stator body is politef；Flow groove is offered on described stator body；Described stator body is fixed on rotation platform by described fixing screw；Described number of bearings is two, is embedded at the top and bottom of described stator body respectively；Described circlip for shaft quantity is two, and it is embedded in described stator body and is positioned at outside described bearing；The material of described rotating seal is rubber, and quantity is three and is distributed between said two bearing；The material of described rotor is rustless steel, and is positioned in the middle of described stator body.
Its further feature is as follows:
