Problems solved by technology

The problems of this welding process are: 1. Since the connection between the inlet pipe and the outlet pipe is a circular arc transition, the welding point is located on the outer surface, even after polishing, the weld seam at the junction of the inlet pipe and the outlet pipe can be seen , it is impossible to ensure that the surface of the triangular valve reaches the ideal smoothness, resulting in poor surface consistency of the triangular valve; 2. Same as the integral casting, the triangular valve after split welding also needs to be polished as a whole, which is more difficult to polish and increases. Production costs, but also not environmentally friendly

Embodiment 1

[0054] Such as Figure 7 and Figure 8 As shown, the angle valve includes an angle valve main body 1 and an angle valve joint 2, the angle valve joint 2 is cylindrical, the angle valve joint 2 is fixed on the angle valve main body 1 to form a valve body, and the valve body has a valve cavity. The spool is loaded into the valve cavity from one end of the angle valve main body 1, and a handle is installed on the spool. The angle valve joint 2 communicates with the valve cavity, and the other end of the angle valve main body 1 serves as the water inlet and outlet of the angle valve respectively.

[0055] Such as figure 1 As shown, the manufacturing process of this angle valve includes the following steps:

[0056] a. Preparation of the main body of the angle valve: the raw materials are cut according to the shape and size of the main body of the angle valve 1, the surface is processed and then drilled through the water hole 1a to obtain the main body of the angle valve 1.

[...

Embodiment 2

[0069]This embodiment discloses a positioning tool for positioning the angle valve main body 1 and the angle valve joint 2 in the angle valve manufacturing process of the first embodiment.

[0070] Such as image 3 and Figure 4 As shown, the positioning tooling of the angle valve includes a frame body 4, a V-shaped block 5, a positioning plate 6 and a mandrel 7. The frame body 4 includes a base 4a for shifting the bottom and vertical plates 4b fixed on both sides of the base 4a. A positioning plate 6 is fixed on the upper part of the vertical plate 4b. The positioning plate 6 has an abutment surface 6a and a relief opening 6b. The two sides of V-shaped block 5 have slide block respectively, and the position corresponding to vertical plate 4b and slide block has the chute that matches with slide block, and slide block can slide up and down in corresponding chute so that V-shaped block 5 can be relatively Slide on frame body 4. The frame body 4 is also provided with a drivin...

Embodiment 3

[0075] This embodiment discloses the angle valve manufactured by the angle valve manufacturing process of Embodiment 1, such as Figure 7 and Figure 8 As shown, the angle valve includes an angle valve body 1 and an angle valve joint 2. The angle valve joint 2 is fixed on the angle valve body 1 by welding. One end of the angle valve joint 2 has an arc connection that matches the shape of the outer wall of the angle valve body 1. surface 2a, and when the angle valve joint 2 is installed on the angle valve main body 1, the arc-shaped connection surface 2a is attached to the outer wall of the angle valve main body 1, and the weld 3 between the angle valve main body 1 and the angle valve joint 2 is located inside the angle valve joint 2 . In this embodiment, the angle valve main body 1 and the angle valve joint 2 are fixed by laser welding.

[0076] Such as Figure 7 As shown, there is a valve cavity in the angle valve main body 1, and there is a water passage hole 1a connected...

Abstract

The invention provides an angle valve as well as an angle valve manufacturing process and a positioning tool, and belongs to the technical field of valves. The angle valve manufacturing process solves the problems that an existing triangular valve manufacturing method is complex in process and is not environmentally-friendly, and surface consistency of the produced angle valve is relatively poor. The angle valve manufacturing process comprises the following steps: a, manufacturing an angle valve main body; b, manufacturing an angle valve joint; c, positioning the angle valve main body and the angle valve joint by laser welding, enabling the arc-shaped connecting surface of the angle valve joint to fit to the outer wall of the angle valve main body, integrally welding the angle valve main body and the angle valve joint inside the angle valve joint through laser welding, and injecting a laser beam from an inner hole of the angle valve joint; d, inspecting; e, assembling; and f, carrying out finished product inspection. The angle valve manufacturing process simplifies the process, improves producing and processing efficiency, and is more environmentally-friendly; and the outer surface of the manufactured valve body does not have a welding seam, so that the valve body is more flat and smooth, is better in consistency, and is better in mechanical property.

Description

technical field [0001] The invention belongs to the technical field of valves, and relates to an angle valve, in particular to an angle valve, an angle valve manufacturing process and a positioning tool. Background technique [0002] Angle valve is an angle globe valve, which is widely used in the field of sanitary ware. The water outlet of the angle valve is at right angles to the water inlet, and the other end is equipped with a handle to control the opening or closing of the angle valve. At present, the valve body of the angle valve is usually processed by integral casting or split welding. [0003] For the integral casting of angle valves, the valve body blanks of the angle valves are first made by sand casting, and then the valve body blanks are subjected to heat treatment and surface treatment, and then the surface finish of the valve body blanks meets the design requirements through polishing, and finally the valve body and The valve core and other parts are assembl...
