In the fixing device for the valve of the water inlet ball valve, the annular end surface of the support ring is provided with an annular pad; and the surface of the annular pad is also embedded with a magnetic absorption column.
A method for installing a fixing device of a valve of a water inlet ball valve comprises the steps of symmetrically placing two tools on the left side and the right side of the water inlet ball valve, and fixing the tools and the water inlet ball valve through bolts.
In the installation method of the water inlet ball valve fixing device, the limiting groove on the flange plate is matched with the limiting step on the water inlet ball valve body to form positioning, and the bolt penetrates through the bolt hole on the flange plate and the bolt hole on the water inlet ball valve body to fix the flange plate and the water inlet ball valve body.
In the installation method of the fixing device for the valve of the water inlet ball valve, the valve spigot on the support ring is matched with the fixed ring surface of the valve of the water inlet ball valve to support the valve.
Compared with the prior art, the invention has the advantages that the two sides of the valve body are respectively provided with the tooling, the support ring on the flange plate is matched with the convex table surface of the valve body to form positioning, and the positioning and the fixing of the valve body are completed by connecting the support ring with the original threaded hole of the valve body through the bolt; the outer end of the inner wall of the support ring is provided with a valve spigot matched with the valve fixing ring surface, so that the valve can be completely fixed, and the structure of the tool is greatly simplified. Meanwhile, the limiting groove is formed in the valve body, so that the further limiting and fixing effects are achieved, and the stability of fixing the valve body and the valve is guaranteed. The two sides of the valve body are respectively provided with the tool, so that the valve body is simple in structure and convenient to install, and the stability between the valve body and the valve can be effectively improved; when the valve body or the valve is processed, the valve cannot move freely, relative displacement cannot occur between the valve body and the valve, and the maintenance size of the valve body is effectively ensured; through the structure, the aim of fixing the valve and the valve body relatively is fulfilled safely and reliably. In addition, the valve body and the valve can be fixed through the tool to form a complete machine, and the machine tool can be conveniently machined and maintained in the later period. The invention has the characteristics of convenient installation and capability of effectively improving the fixing stability.
In addition, the annular pad is arranged on the end face of the support ring, and the magnetic absorption column is embedded on the surface of the annular pad, so that the damage to the surface of the valve can be effectively prevented, the magnetic absorption column can be adsorbed on the surface of the valve, and the installation firmness is further improved.
