Flow control valve

This creation is a flow control valve, especially a flow control valve that can stably control fluid flow.

A common flow control valve for fluids, used as a gas or liquid transfer switch for residential or industrial purposes, such as household gas transportation or factory chemical gas, liquid transportation, etc., and even used to mix various types of gases or liquids. The control valve, for example, is used to mix and manufacture the cutting fluid used in the machine tool. The mixing of the cutting fluid is controlled by the flow control of the flow control valve with water and cutting oil, and is mixed with each other according to a certain ratio, so the flow control valve of the fluid is used as Flow control is important in conveying and mixing operations.

Therefore, the Republic of China Patent No. I296030 discloses a "flow control valve" which is shown in Fig. 1 of the case No. I296030, which includes a valve body, a joint, a valve ball, a pad body, a valve stem and a nut. In this technical solution, when a fluid flow with a large pressure passes through the valve ball, the valve ball is prone to deflection, or the valve ball and the valve stem are prone to slack after being used for a period of time, and the fluid flows through the valve. In the case of a ball, there is a possibility that the flow rate cannot be precisely controlled, and in particular, in the fluid mixing operation, the fluid quality of the mixed fluid is liable to be poor. For example, if the cutting fluid described above has poor mixing quality, a defective cutting fluid product is produced, for When applied to all kinds of tool machining, the cutting fluid has enough heat to absorb the tool and the workpiece to maintain the temperature of the working environment. Stable, and improve the lubricity between the workpiece and the tool to reduce tool wear and extend tool life, and prevent mechanical and tool rust. If the mixing quality of the cutting fluid is not good, it is easy to produce tool machining defects. Therefore, how to improve the above-mentioned deficiencies, that is, the technical difficulties that the applicant of this case wants to solve.
