Abstract
The utility model discloses a valve lining used for a stepped valve rod. The valve lining used for the stepped valve rod comprises a valve lining body (1). A lining plate body (2) extends out of the lower end of the valve lining body (1). The valve lining used for the stepped valve rod is characterized in that limiting steps (101) are arranged in the inner cavity of the valve lining body (1), and a circular guiding arc (102) is arranged on the opening position of the valve lining body (1). The valve lining used for the stepped valve rod can be used for abrasion-resisting protection of the stepped valve rod, and is simple in structure and convenient to manufacture.
Description
Technical field
The utility model belongs to machinery valve accessory technical field, specifically just relates to a kind of valve bushing for the step valve rod.
Background technique
Lining be the ring set of liner effect in the valve applications field, lining is within valve gap, the anticorrosive materials such as normal operation teflon or graphite are used for seal action.Wrap valve rod, worn and torn, can be convenient for changing.If without lining, after the wearing and tearing, replacing be part.So changing into is resleeve more, during design, just with the lining lower hardness, it is become in friction pair hold mill spare.Easy to process because of it, replacement cost is low, also easily changes.Having guide function etc. is widely used by the time.
As shown in Figure 1, Chinese patent 200620039212.1 discloses a kind of lining, wall is provided with at least one oil groove within it, the part of the additional loss that the butter of storage in the groove in use can continue is arranged, and therefore, the lubricating condition of revolute pair is better between lining and the running shaft, wearing and tearing are few, and then the working life of lining and running shaft is longer, and does not have abnormal sound when using.
At present, traditional lining just is applicable to straight tube shape valve rod, but the present valve rod type moon is more, the stepped shape valve rod occurs, and existing lining can't effectively play the effect of protection.
The model utility content
Just be applicable to straight tube shape valve rod for existing valve bushing; can't be applicable to the technological deficiency of stepped shape valve rod, the utility model provides a kind of valve bushing for the step valve rod, can be used in the anti-wear protection to the step valve rod; whole bush structure is simple, and is easily manufactured.
Technological scheme,
In order to realize above-mentioned technical purpose, a kind of valve bushing for the step valve rod of the utility model design, it comprises the valve bushing body, valve bushing body lower end is extended with the lining disk body, it is characterized in that: be provided with limited step in the described valve bushing chamber body, described valve bushing body oral area is provided with the guiding circular arc.
Wide 0.5～the 3mm of described limited step.
Described guiding circular arc arc round angle is 3mm.
The loose 3mm of described lining disk body, high 3mm.
Beneficial effect
A kind of valve bushing for the step valve rod that the utility model provides can be used in the anti-wear protection to the step valve rod, and whole bush structure is simple, and is easily manufactured.
