Abstract
The invention discloses a novel bushing which comprises a cylindrical outer bushing, an inner bushing and a cylindrical polyurethane layer positioned between the outer bushing and the inner bushing. Each of the outer bushing and the inner bushing is made by stainless steel. Compared with rubber bushings in the prior art, the novel bushing has the advantages of high strength and long service life and is low in loss. The invention further discloses a manufacturing process of the novel bushing. Quality and performance of the novel bushing are improved.
Description
Technical field
The invention belongs to field of electromechanical equipment, relate to the lining of a kind of application and valve.
Background technique
Lining has been the ring set of liner effect, and in valve applications field, lining is within valve gap, and the anticorrosive materials such as general use rubber, for seal action.Lining wraps valve rod, has worn and torn, and can change.If without lining, after wearing and tearing, replacing be part.Existing lining becomes and holds mill part in friction pair, usually needs to change, and in order to reduce the replacing number of times of lining, and ensureing lining role, now providing a kind of improvement project.
Summary of the invention
The object of the invention is to overcome prior art defect, provide a kind of performance better, reduce and change the lining of number of times and the preparation process of this lining.
Object of the present invention can be achieved through the following technical solutions:
A kind of Novel lining, comprise cylindric external bushing, neck bush and polyurethane layer cylindric between external bushing, neck bush, described external bushing, neck bush are stainless steel.
Polyurethane full name is polyurethane, is the general designation of the macromolecular compound containing repetition carbamate groups on main chain.Polyurethane material, purposes is very wide.
Beneficial effect of the present invention: the present invention is relative to rubber bushing in prior art, there is the feature of product strength, long service life, the loss of this product is low, the invention also discloses the preparation process of this Novel lining simultaneously, improves quality and the performance of product.
Accompanying drawing explanation
For the ease of it will be appreciated by those skilled in the art that the present invention is further illustrated below in conjunction with accompanying drawing.
Fig. 1 is structural representation of the present invention.
Embodiment
As described in Figure 1, a kind of Novel lining, comprises the external bushing 1 of cylindrical shape, neck bush 2 and the polyurethane layer 3 between external bushing 1, neck bush 2, and described external bushing 1, neck bush 2 are stainless steel.This lining is the property utilizing polyurethane, replaces the rubber in prior art lining, the product of a kind of row of formation.But due to the property of polyurethane, also make polyurethane not too easily be bonded at external bushing 1 internal surface and neck bush 2 outer surface.External bushing 1, neck bush 2 and polyurethane layer 3 are cylindric or tabular.
The preparation process of lining of the present invention, comprises the following steps:
A, get the steel pipe with external bushing 1, neck bush 2 same diameter, the diameter of stainless-steel pipe is equal to the diameter of external bushing 1, neck bush 2.Measure liner size, utilize cutting machine to cut off stainless-steel pipe, make external bushing 1, neck bush 2, and chamfering setting is carried out to external bushing 1, neck bush 2 two ends;
B, phosphatization or zinc-plated process are carried out to external bushing 1 outer surface, ensure that the attractive in appearance of product, also prevent product from getting rusty;
C, at external bushing 1 internal surface and neck bush 2 outer surface adhesive, adhesive is Kai Muluoke 213 type or Kai Muluoke 219 type;
D, external bushing 1 and neck bush 2 are placed in a mold and heated it, external bushing 1, neck bush 2 are heated to 90-110 DEG C, and mold heated is to 110-130 DEG C;
E, unlatching injection machine adjust the temperature to 175-185 DEG C, polyurethane is added in injection machine, be heated to molten state, melt polyurethane state is injected in mould, namely in the middle of external bushing 1, neck bush 2, under normal temperature, be cooled to room temperature, form polyurethane layer 3, artificial deburring is carried out to the product formed, forms a kind of Novel lining.
By Novel lining of the present invention and traditional lining, namely carry out non-stop run Experimental Comparison in 0-72h with rubber bushing, comparative trial data are as table 1:
Table 1
Known to table 1, the present invention, relative to rubber bushing in prior art, has the feature of product strength, long service life, and the loss of this product is low, the invention also discloses the preparation process of this Novel lining simultaneously, improves quality and the performance of product.
Above content is only to structure example of the present invention and explanation; affiliated those skilled in the art make various amendment to described specific embodiment or supplement or adopt similar mode to substitute; only otherwise depart from the structure of invention or surmount this scope as defined in the claims, protection scope of the present invention all should be belonged to.
Claims (2)
