Abstract

The utility model relates to a wear-resistant ball valve body which is composed of the ball valve body and a shaft seat. The shaft seat and the ball valve body are manufactured in an integrated manner, a shaft hole is arranged on the shaft seat, wherein a wear-resistant layer is uniformly fused on the spherical surface of a main body of the ball valve body, and the wear-resistant layer is a CoCrW metal layer. The wear-resistant ball valve body has simple structure, leads scientific design, and adopts the TIG build up welding technology to fuse a CoCrW metal layer on the surface of the main body of the ball valve body, so as to greatly improve the wear-resistant performance of the ball valve body, prolong the service life of the ball valve body, and realize the purposes of energy saving as well as emission reduction.

Description

A kind of wear resistance ball valve body

Technical field

The invention belongs to employed a kind of wear resistance ball valve body on valve class, the especially ball valve of mechanical engineering field.

Background technique

Mechanical sealing element is an a kind of envelope formula Sealing, often is applied to the out of use places of ordinary rubber Sealing such as high speed, high temperature and deep-etching; And mechanical sealing element requires dynamic and static ring when relative movement (rotation), both required corrosion-resistantly, high temperature resistant, also requires metal and intermetallic wear-resistant in high-speed friction.For ball valve, ball valve body often needs rotation, and the ball valve body sphere valve seat that often need rub causes ball valve body itself will possess higher wear-resisting property thus.Existing ball valve body adopts stainless steel to make, and stainless steel material is corrosion-resistant except having, the resistance to high temperature, also have certain wear-resisting property.But ball valve body is as the rotation parts, and the abrasive resistance that only relies on material self is far from being enough, is very easy to cause ball valve body self to influence the normal use of ball valve because of wearing and tearing, and even scraps.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of ball valve body that has than high-wear resistance is provided.

The utility model solves its technical problem and is achieved through the following technical solutions:

A kind of wear resistance ball valve body is made of ball valve body, axle bed, and axle bed and ball valve body are made into integration, and is shaped on axis hole on axle bed, an even deposited wearing layer on the sphere of ball valve body body wherein, and this wearing layer is the CoCrW metal layer.

And, on the sphere of ball valve body body evenly deposited CoCrW metal layer be to adopt the TIG bead-welding technology deposited.

Advantage of the present utility model and beneficial effect are:

1. this ball valve body deposited antifriction metal (AFM) on the ball valve body sphere, economical with materials cost not only can make the volume of ball valve body reduce, cost reduces, and technology is simple, increases the service life, and is a kind of not only economy but also simple and effective technological method.

2. this ball valve body is at the deposited CoCrW metal layer of the body surface of ball valve body, and adopts the TIG bead-welding technology, has improved the wear-resisting property of ball valve body effectively.

3. the utility model is simple in structure, and design science adopts the TIG bead-welding technology at the deposited CoCrW metal layer of the body surface of ball valve body, has greatly improved the wear-resisting property of ball valve body self, has prolonged the working life of ball valve body, has realized the purpose of energy-saving and emission-reduction.

Embodiment

The utility model is described in further detail below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.

A kind of wear resistance ball valve body is made of ball valve body 1, axle bed 2, and axle bed is two and is made into integration with ball valve body, is shaped on axis hole 5 on axle bed, and ball valve body and axle bed adopt stainless steel material to make.Innovative point of the present utility model is: an even deposited wearing layer 3 on the sphere of ball valve body body 4, this wearing layer is the CoCrW metal layer, and adopts the TIG bead-welding technology deposited.

The utility model adopts the TIG bead-welding technology at the deposited CoCrW gold of the body surface of ball valve body Belong to layer, because that the TIG built-up welding has investment cost is low, the advantages such as flexible operation and strong adaptability, And the carbide of tungsten is separated out in built-up welding easily, because the formation of the carbide of tungsten can make built-up welding The hardness of layer is improved, and also can improve the wearability of overlay cladding simultaneously, and then Effective Raise The anti-wear performance of ball valve body.

Claims (2)

1. a wear resistance ball valve body is made of ball valve body, axle bed, and axle bed and ball valve body are made into integration, and is shaped on axis hole on axle bed, it is characterized in that: an even deposited wearing layer on the sphere of ball valve body body, this wearing layer is the CoCrW metal layer.

2. a kind of wear resistance ball valve body according to claim 1 is characterized in that: on the sphere of ball valve body body evenly deposited CoCrW metal layer be to adopt the TIG bead-welding technology deposited.
