Problems solved by technology

The valve body of the inclined ball valve is usually made by casting. The cast inclined ball valve body has low density, the valve body has pores, and is easy to leak. Especially the inclined ball valve used on industrial pipelines, due to the high pressure of industrial pipelines Liquid leakage occurs. If the liquid in the pipeline is toxic or harmful to the human body, once it leaks, it will cause serious consequences and even endanger personal safety. Therefore, the cast inclined-plane ball valve is not suitable for industrial applications with high pressure levels. pipeline use

Embodiment Construction

[0035] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0036] The manufacturing method of inclined-plane ball valve of the present invention, its concrete steps of preparing inclined-plane ball valve valve body are:

[0037] Step 1, according to the valve body specifications of the inclined ball valve, cut the round steel bar;

[0038] Step 2, preparing the blank of the inclined ball valve body: at a high temperature of 600-800 ° C, the round steel bar is made soft, and then put it into the rough mold of the inclined ball valve body, and punched into an inclined ball valve with a friction punch When the temperature of the rough billet of the inclined ball valve body is still high, put the rough billet of the inclined ball valve body into the mold of the fine billet of the inclined ball valve body, and use a friction punch to punch it into a fine billet of the inclined ball valve body. Put the valve body blank in...

Abstract

The invention relates to a method for manufacturing a beveled ball valve, and relates to a process for manufacturing a ball valve. The method is characterized by comprising the following steps: 1, cutting out a round steel bar according to the specification of a valve body of the beveled ball valve; 2, manufacturing a blank of the valve body of the beveled ball valve; 3, lathing a middle way; 4, milling the upper edge and lower edge of the middle way; 5, milling a sealing surface of the middle way; and 6, drilling bolt holes. In the method for manufacturing the beveled ball valve, the beveledball valve is machined by a forging method through a lathe and a milling machine, and the valve body is high in density and has no air holes, is suitable to be used in pipelines with high pressure rating in industry, and guarantees personal safety and production safety.

Description

technical field [0001] The invention relates to a manufacturing process of a ball valve, in particular to a manufacturing method of an inclined-plane ball valve. Background technique [0002] Inclined ball valve is a common ball valve in the market now, its specific structure is as follows: figure 1 As shown, including 1 valve body, 2 valve seat, 3 valve core, 4 wound sealing gasket, 5 adjusting spring, 6 valve cover, 7 packing, 8 valve stem, 9 handle, 10 nut, 11 bolt and nut, 12 stem nut. The valve body of the inclined ball valve is usually made by casting. The cast inclined ball valve body has low density, the valve body has pores, and is easy to leak. Especially the inclined ball valve used on industrial pipelines, due to the high pressure of industrial pipelines Liquid leakage occurs. If the liquid in the pipeline is toxic or harmful to the human body, once it leaks, it will cause serious consequences and even endanger personal safety. Therefore, the cast inclined-plan...
