The present invention relates to a sanitary flow regulating globe valve, and more specifically, a double cylinder, a valve body in which the double cylinder is coupled to the upper side, is driven by the double cylinder, and a stem for controlling the flow rate inside the valve body. It relates to a sanitary flow control glove valve to include.

According to the advancement of the industry, when a small amount is also injected into the line, such as a pharmaceutical manufacturing process and a food additive input process, which require hygiene of materials and raw materials, there is a need to overcome limitations in flow control.

Ball valves and sanitary butterfly valves, which are frequently used in existing sanitary piping lines, can control the flow rate within the opening / closing range within 45 degrees. Since then, there has been a demand for a sanitary valve capable of precise flow control because flow control is impossible.

Sanitary valve means sanitary process equipment, stainless valves used in manufacturing and production facilities in the food, pharmaceutical, and chemical industries, and transportation equipment and piping pipes, and means transportation equipment produced according to the standards required by the industry. do.

The valve is a device that opens and closes a flow path through which fluid flows or stops, and is classified into a ball valve, a butterfly valve, and a globe valve according to the opening and closing method (see FIG. 1 below).

The food, pharmaceutical, and chemical industries involve key processes to isolate, convert, and prevent the flow of liquids such as gas, steam, water, and chemicals, which are the raw materials for product production. It must be equipped with essential equipment (see Fig. 2 below). In particular, the globe valve can be finely adjusted unlike the ball-type and butterfly-type valves, and has been used with the highest reliability in the industry requiring fine material input control.

Existing globe valves are basically cylinders of thrust standard to smoothly drive valves, yokes that connect valves and cylinders (drives), plugs that directly open and close transport of materials, and plugs up and down with the power of the actuators It is composed of a transmission body (rod column) stem of driving force to move to, a seat that supports sealing by contact with a plug, and a valve body that protects the material from the passage and external impact.

However, in the case of the above-described conventional glove valve, the structure is complicated with about 20 kinds of parts, so it takes about 30-40 minutes for disassembly / assembly, about 30-40 minutes for reassembly after sterilization, and a total of 60-90 minutes. There is a limit to maintenance efficiency.

In addition, the vertical structure design for buffing convenience (refer to FIG. 3 below, 1, 2, 3 arrow direction before assembly) and the result of strengthening the design of the adhesive force. Of course, by adopting a single-layered cylinder structure, there is a problem that requires twice the area to generate the same driving force compared to a double cylinder.

In order to solve the above-mentioned problem, KR Patent Application No. 10-2007-0074365 (invention name: flow control valve) is formed with an inlet for fluid and an outlet for fluid, and the fluid between the inlet and the outlet A passage in which a flow rate of the flow is regulated is formed inside, and a valve housing is formed in an outer portion of the passage; A valve head having a slide portion that slides while blocking the flow of fluid in the passage of the valve housing; A receiving body in which a lower outer surface portion is inserted and coupled to the tube portion of the valve housing, openings are formed on both sides of the upper and lower sides, and an inner space connecting the openings on both sides is formed; A rotating member inserted into the inner space through the upper opening of the receiving body and a spiral formed in the lower outer circumference; A spiral hole through which the lower outer circumference of the rotating member can be inserted and screwed is formed, and the rotation of the rotating member slides up and down in the inner space while rotation is prevented with respect to the lower inner wall of the receiving body. Being, the valve head is a moving member coupled to the lower end by a coupling screw; And it is coupled to the upper portion of the rotating member discloses a flow control valve including a rotating handle to provide easy rotation of the rotating member.

However, although the above-mentioned patent document has an advantage of simplifying the glove valve structure, it has not sufficiently solved the above problems, such as adopting a two-layer structure for the valve body.
