Description

Technical Field

[0001] The utility model belongs to the technical field of four-way valves, and in particular relates to a four-way valve used in high-pressure pipelines. Background Art

[0002] A through-valve is a special valve used in piping systems, with multiple inlets and outlets, that can control fluid flow between multiple pipes. Through-valve applications in high-pressure pipelines, especially those used to control pressure in high-pressure sterilization environments, need to withstand relatively high pressures. Therefore, such valves are typically manufactured from relatively hard steel. Large steel plates, which are conventional raw materials for processing, require xy-axis cutting to create blanks before processing. These blanks then need to be cut and shaped, resulting in low processing efficiency and high manufacturing costs. Utility Model Content

[0003] The purpose of the utility model is to provide a four-way valve applied to a high-pressure pipeline to solve the technical problems described in the background technology.

[0004] The four-way valve used in high-pressure pipelines includes a valve body cut from a round steel bar, and the four sides of the valve body are provided with centrally symmetrical vertical surfaces. Each of the vertical surfaces is provided with a frustum hole for hard-sealed connection with the high-pressure pipeline, and the frustum hole is provided with a channel inwardly, and the channel extends inwardly in a straight line to intersect with the channels of all other frustum holes.

[0005] According to the technical solution, the utility model can achieve the following beneficial effects:

[0006] 1. Since the valve body is cut from round steel bars, the round steel bars used to make four-way valves are easier to transport, store and prepare than large steel plates.

[0007] 2. Since there are fewer thick plates on the market, round steel bars are now easier to buy for large steel plates;

[0008] 3. When processing the valve body, only one cut is required on the round steel bar to form the blank for preparing the valve body, thereby simplifying the number of cuts and improving processing efficiency and manufacturing costs;

[0009] 4. Since the four sides of the valve body are all centrally symmetrical vertical surfaces, and the channels located on the vertical surfaces extend inward in a straight line to intersect with the channels of all other frustum holes, it is convenient to process the blank into a four-way valve;

[0010] 5. Since the open end of the channel is provided with a truncated cone hole, the channel of the four-way valve can be conveniently and stably hard-sealed connected to the high-pressure pipeline.

[0011] In order to further optimize the above technical solution, it can be optionally combined with one or more of the following implementation methods without conflict.

[0012] In some embodiments, the vertical surface is provided with an overflow space, and the frustum hole is located in the overflow space;

[0013] According to the technical solution, when the high-pressure pipeline is connected to the conical hole, or when overflow occurs due to excessive pressure in the channel between the high-pressure pipeline and the valve body, the overflowing material can be collected and the material can be prevented from being ejected outward.

[0014] In some embodiments, the outer end of the overflow space is provided with an opening, the inner wall of the opening is provided with an internal thread for fixing the blocking member, and the overflow space is provided with a safety overflow hole;

[0015] According to the technical solution, the material in the overflow space can be discharged through the overflow hole and transported to the storage area, so as to facilitate the collection of the overflowed material.

[0016] In some embodiments, the inclined surface of the truncated cone hole is 62°, the outer diameter of the truncated cone hole is 9 mm, and the inner diameter of the truncated cone hole is 5 mm;

[0017] According to the technical solution, the high-pressure pipeline can be more stably hard-sealed to the truncated cone hole.

[0018] In some embodiments, the overflow hole has a diameter of 3 mm;

[0019] According to the technical solution, when the pressure in the pressure space is too high, the material in the pressure space overflows into the overflow space, and the overflow hole can relieve the pressure in the overflow space or the space connected to the high-pressure pipe, thereby achieving overpressure protection.

[0020] In some embodiments, an outer arc with a radius of 50 mm is formed between two adjacent vertical surfaces, and a distance between the vertical surfaces on both sides of the valve body is 90 mm;

[0021] According to the technical solution, the four-way valve can be rotated to align its four sides with the corresponding high-pressure pipes.

[0022] In some embodiments, the thickness of the valve body is 38 mm, and the maximum diameter of the valve body is 90 mm;

[0023] According to the technical solution, the four-way valve can effectively improve its own strength by using relatively less material through this parameter ratio. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail with reference to the accompanying drawings. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the concept of the present invention.

[0031] As shown in 1 to 3 , this specific embodiment provides a four-way valve for high-pressure pipelines, which includes a valve body 1 cut from a round steel bar. The thickness of the valve body 1 is 38 mm, and the maximum diameter of the valve body 1 is 90 mm.

[0032] The four sides of the valve body 1 are provided with centrally symmetrical vertical surfaces 11 , and an outer arc 12 with a radius of 50 mm is formed between two adjacent vertical surfaces 11 . The distance between the vertical surfaces 11 on both sides of the valve body 1 is 90 mm.

[0033] An overflow space 4 is provided in each vertical surface 11 , an opening 41 is provided at the outer end of the overflow space 4 , an inner wall of the opening 41 is provided with an internal thread 42 for fixing the blocking member, and a safety overflow hole 43 is provided in the overflow space 4 , and the diameter of the overflow hole is 3 mm.

[0034] Each of the overflow spaces 4 is provided with a truncated cone hole 3 for hard-sealed connection with the high-pressure pipeline 2. The inclined surface of the truncated cone hole 3 is 62°, the outer hole diameter of the truncated cone hole 3 is 9 mm, and the inner hole diameter of the truncated cone hole 3 is 5 mm. The truncated cone hole 3 is provided with a channel 31 inwardly, and the channel 31 extends inwardly in a straight line until it intersects with the channels 31 of all other truncated cone holes 3.

[0035] Since the valve body 1 is cut from a round steel bar, the raw material round steel bar for manufacturing the four-way valve is easy to transport, store and prepare compared to large steel plates. In addition, since there are fewer thick plates on the market, the round steel bar is easy to purchase compared to large steel plates.

[0036] When processing the valve body 1, only one cutting is required on the round steel rod to form a blank for preparing the valve body 1, thereby simplifying the number of cuttings and improving processing efficiency and manufacturing costs; at the same time, since the four sides of the valve body 1 are all centrally symmetrical vertical surfaces 11, and the channel 31 located on the vertical surface 11 extends inward in a straight line to intersect with the channels 31 of all other said frustum holes 3, it is convenient to process the blank into a four-way valve; and the opening 41 end of the channel 31 is provided with a frustum hole 3, which enables the channel 31 of the four-way valve to be conveniently and stably hard-sealed and connected to the high-pressure pipeline 2.

[0037] It should be understood that the above-described specific embodiments of the present invention are intended only to illustrate or explain the principles of the present invention and do not constitute a limitation of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the scope of protection of the present invention. In addition, the appended claims of the present invention are intended to cover all variations and modifications that fall within the scope and metes and bounds of the appended claims, or equivalents of such scope and metes and bounds.
