Abstract
The invention discloses a method for recycling a scrapped valve body with poor body-sleeve fit. The valve body comprises a body-sleeve structure; the body-sleeve structure is formed by assembling a valve body and a valve sleeve in an interference fit mode; the valve body is connected to the periphery of the valve sleeve in a sleeving mode; when the body-sleeve structure is in poor fit, a certain gap is formed between the valve body and the valve sleeve. The method for recycling the scrapped valve body specifically comprises the steps that when the body-sleeve structure of the valve body is in poor fit, the body-sleeve structure is disassembled; an inner hole of the valve body of the original body-sleeve structure is remachined; then a new valve sleeve is assembled in the interference fit mode, the outer diameter of the new valve sleeve is matched with the inner hole of the remachined valve body, and a body-sleeve structure with good fit is formed again. According to the method, by disassembling the original body-sleeve structure with poor fit and adjusting the fit dimension of the valve body and the valve sleeve again, a new body-sleeve fit structure is achieved, and the quality problem of the body-sleeve structure with poor fit is solved; the valve body is prevented from being scrapped directly, so that the service life cycle of a product is prolonged, the production cost is reduced, and the waste product quantity is reduced.
Description
Technical field
What the present invention relates to a kind of body cover poor fit scraps valve body recovery method.
Background technology
Valve body in use, due to the relative motion between long atmospheric corrosion and parts, makes the body of valve body cover fit quality bad, thus easily causes valve body to sew, affect Total Product performance.At present, for the valve body of body cover poor fit, be all directly scrap, cause the life cycle of product short, production cost is higher.
Summary of the invention
The object of the invention is to: for above-mentioned Problems existing, provide a kind of valve body scrapped because of body cover poor fit that can make to realize the method effectively reclaimed.
Technical scheme of the present invention be achieved in that a kind of body cover poor fit scrap valve body recovery method, described valve body comprises body nested structure, described body nested structure is formed by interference fit by body and cover, described body is socketed in the periphery of cover, when described body nested structure poor fit, certain interval is there is between described body and cover, it is characterized in that: described in scrap valve body recovery method be specially: when the body nested structure poor fit of valve body, body nested structure is disintegrated, the internal orifice dimension of body in substance nested structure is reprocessed, then by new cover that interference fit top external diameter matches with the internal orifice dimension of body after reprocessing, reconstitute the body nested structure of no-float, in the body nested structure ressembled, the internal orifice dimension of body and the external diameter of cover are greater than the internal orifice dimension of body and the external diameter of cover in substance nested structure respectively.
The present invention is by the body nested structure of original poor fit of disintegrating, and it is readjusted to the fit dimension of body and cover, realize new body cover fit structure, solve the quality problems of the body nested structure of poor fit, avoid valve body and directly scrapped, thus extend the life cycle of product, save production cost, reduced rejection number, be not only applicable to the body of railway brake valve, the maintenance of cover cooperation class, also be applicable to fit dimension change, but do not affect other bodies cover cooperation field of product function.
Detailed description of the invention
The present invention is described in detail below.
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with embodiment, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Embodiment: a kind of body cover poor fit scrap valve body recovery method, described valve body comprises body nested structure, described body nested structure is formed by interference fit by body and cover, described body is socketed in the periphery of cover, when described body nested structure poor fit, there is certain interval between described body and cover, thus cause valve body to sew, affect Total Product performance, and existing processing method is all directly scrapped by the valve body of body nested structure poor fit.
The recovery method scrapping valve body of the present invention is specially: when the body nested structure poor fit of valve body, body nested structure is disintegrated, the internal orifice dimension of body in substance nested structure is reprocessed, then by new cover that interference fit top external diameter matches with the internal orifice dimension of body after reprocessing, reconstitute the body nested structure of no-float, in the body nested structure ressembled, the internal orifice dimension of body and the external diameter of cover are greater than the internal orifice dimension of body and the external diameter of cover in substance nested structure respectively, like this, the body nested structure that there is mass defect is redesigned, processing, assembling, finally meet Total Product performance and appearance requirement, be not only applicable to the body of railway brake valve, cover coordinates class maintenance, also be applicable to fit dimension change, but do not affect other bodies cover cooperation field of product function.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
Claims (1)
1. body cover poor fit scrap valve body recovery method, described valve body comprises body nested structure, described body nested structure is formed by interference fit by body and cover, described body is socketed in the periphery of cover, when described body nested structure poor fit, certain interval is there is between described body and cover, it is characterized in that: described in scrap valve body recovery method be specially: when the body nested structure poor fit of valve body, body nested structure is disintegrated, the internal orifice dimension of body in substance nested structure is reprocessed, then by new cover that interference fit top external diameter matches with the internal orifice dimension of body after reprocessing, reconstitute the body nested structure of no-float, in the body nested structure ressembled, the internal orifice dimension of body and the external diameter of cover are greater than the internal orifice dimension of body and the external diameter of cover in substance nested structure respectively.
