Problems solved by technology
[0002] At present, the balance valves on the market are widely used. The balance valves have pressure guide holes, some are external, and some are built-in. The external pressure guide tube balance valve It is bulky and heavy, and it is easy to be damaged during transportation. Therefore, the balance valve with an external pressure guiding tube is basically replaced by a balancing valve with a built-in pressure guiding hole. It can realize its function, but because the pressure guide hole is deep, it is easy to cause the drill bit to break when drilling, even if the drill bit is not damaged, the processing efficiency of the pressure guide hole is low, thereby reducing the production efficiency of the balance valve

Embodiment Construction
[0010] As shown in the figure, by casting, a pressure guide hole 2 communicating with the flow channel of the valve body is provided on one side of the valve body 1 .
[0011] The pressure guide hole is arranged obliquely on the wall of the valve body, one end communicates with the valve body, and the other end communicates with the flow channel of the valve body.
[0012] The inclined pressure guide hole of the present invention is completed by casting the valve body at one time, saving the post-drilling process.

The invention provides a dynamic equilibrium electric regulating valve with a cast pressure guide hole. Through casting, one side of a valve body is provided with the pressure guide hole communicated with a valve body flowing channel. The pressure guide hole is formed in the wall of the valve body in an inclined mode, one end of the pressure guide hole is communicated with the valve body, and the other end of the pressure guide hole is communicated with the valve body flowing channel. According to the dynamic equilibrium electric regulating valve, the pressure guide hole is formed in the cast valve body, weight of a blank can be lightened, punching is omitted, pressure guide reliability of the valve is increased, production cost can be lowered, and efficiency is improved. The dynamic equilibrium electric regulating valve is suitable for serving as an electric regulating valve with a built-in pressure guide hole.
Description
technical field [0001] The invention optimizes and improves the manufacturing process of the pressure guide hole of a balance valve, and in particular relates to a dynamic balance electric regulating valve with a cast pressure guide hole. Background technique [0002] The balance valves currently on the market are widely used. The balance valves have pressure guide holes, some are external, and some are built-in. The external pressure guide tube balance valve is bulky and heavy, and it is easy to be damaged during transportation. The balance valve of the pressure guide tube is basically replaced by the balance valve with built-in pressure guide holes. At present, the built-in pressure guide holes on the market are all post-processed. When it is used, it is easy to cause the drill bit to break. Even if the drill bit is not damaged, the processing efficiency of the pressure guide hole is low, thereby reducing the production efficiency of the balance valve. [0003] Invention...
