With the high development of the industry, when a small amount of the raw materials are put into production lines such as a medicine manufacturing process, a food additive putting process and the like which have sanitary requirements on the raw materials and the materials, the limitation of flow regulation needs to be overcome.
The ball valve and the sanitary butterfly valve commonly used in the existing sanitary distribution pipeline can adjust the flow value within the opening and closing range of 45 degrees, but when the flow value exceeds 45-90 degrees, the flow passage area of the fluid is enlarged, and when the flow value reaches more than 45 degrees, the flow cannot be controlled, so that the sanitary valve capable of accurately adjusting the flow is required.
The sanitary valve is sanitary process equipment, refers to stainless steel valves, transportation machines, piping and the like used for manufacturing and producing equipment in the food industry, the pharmaceutical industry and the chemical industry, and refers to transportation equipment produced according to the standard required by the industry.
Valves are machines for opening and closing a flow passage to make or stop a fluid flow, and are classified into ball valves, foot valves, and stop valves according to the opening and closing manner (see fig. 1 below)
The production of products in the food, pharmaceutical, chemical industries and other industries is usually accompanied by a core process for isolating, converting and preventing the mixing of liquid flows of gas, steam, water, chemicals and the like as raw materials, and a valve for controlling the flows is necessary to be equipped (see fig. 2 below). In particular, the shutoff valve is capable of fine adjustment unlike a ball or butterfly type valve, and is most highly reliable in industries requiring adjustment of the input of fine materials.
The structure of the existing shut-off valve basically comprises: a cylinder having a thrust to smoothly drive the valve; a bracket connecting the valve and the cylinder (actuator); the plug valve can be directly opened and closed for material transportation; a transmission body (stem) valve rod of a driving force for moving the plug valve up and down by the force of the driver; the plug valve is connected with a seat supporting sealing; the valve body is protected from the material conveying passage and external impact.
However, the existing stop valve has more than 20 parts, a complex structure, and needs more than 30-40 minutes for disassembly and assembly, and needs 30-40 minutes for reassembly after sterilization by a sterilizer, and needs 60-90 minutes in total, so that the maintenance efficiency is limited.
In addition, when the vertical structure design (see fig. 3, and the arrow directions of 1, 2 and 3 before assembly) required by the convenient polishing processing and the pipeline combination of the valve with the tight adhesion force enhancement design result are needed, the piping has a two-layer structure, so that twice space is needed, and compared with a double-cylinder structure, the area required by the same driving force is doubled.
In order to solve the above problems, KR patent application No. 10-2007- -: a valve housing having an inlet through which a fluid flows in and an outlet through which the fluid is discharged, a passage for adjusting a flow rate of the fluid between the inlet and the outlet being provided inside the valve housing, and a pipe portion being provided outside the passage; a valve head provided with a sliding portion that slides while shutting off the flow of fluid in a passage of the valve housing; the lower outer surface is inserted into the tube of the valve shell and combined, the upper and lower sides are provided with openings, and the containing body is provided with an inner space connected with the openings at the two sides; a rotating member inserted into the internal space through an upper opening of the housing body and having a spiral shape at a lower outer circumferential portion; a moving member having a lower outer peripheral portion into which a screw hole is screwed from above, the rotating member being rotated to prevent the valve head from sliding up and down in an inner space of the housing body while rotating an inner wall of the lower portion of the housing body, the valve head being coupled to a lower end portion of the housing body by a coupling screw; and a rotary handle coupled to an upper portion of the rotary member to facilitate rotation of the rotary member.
However, the above patent documents have an advantage that the structure of the shutoff valve is simplified, but the valve body has a two-layer structure, and the valve body is difficult to manufacture, and the above-mentioned problems cannot be sufficiently solved.
Reference is made in this specification to the most pertinent papers and patent documents, the contents of which are identified. The disclosures of the cited articles and patent documents are incorporated by reference into this specification to further clarify the state of the art to which this invention pertains and the content of this invention.
