Description

Technology Field

[0001] The present invention relates to a valve for an air vent, and more specifically, to an air vent valve in which the valve part and the bolt part configured in the valve are connected in a sliding manner when connected to each other, thereby increasing the connecting force and enabling easy attachment and detachment. Background Technology

[0003] First, if we look at the prior art,

[0004] Generally, air vent valves are installed in liquid transfer piping, such as water, and function to discharge air contained in the water to the outside.

[0006] As described in Utility Model Registration Application No. 2000-0014685, a conventional air vent valve is configured such that a float, which rises and falls according to the water level, is installed in the body, and this float opens and closes the air outlet of a cover installed on the upper side of the body.

[0007] In addition, the air outlet is equipped with a manually openable cap, allowing the user to discharge air by manually opening and closing the cap.

[0009] However, this type of manually operated air vent valve had the problem of being very cumbersome because the user had to operate the valve frequently, as well as the problem of outside air entering the interior.

[0011] Therefore, technology has been developed to solve these problems; for example, as described in Utility Model Registration No. 0199384, the air vent operates automatically and includes a function to block the inflow of external air as well as the inflow of water during repairs.

[0013] However, conventional air vent valves, including the aforementioned Utility Model Registration No. 0199384, have a complex structure in which a check valve, which is the part where air is discharged, is separately provided and installed in a cover, which has the problem of increasing the unit cost of the product due to the increase in the number of parts. Furthermore, since the masking member that opens and closes the air discharge port of the check valve and the float that moves up and down inside the body are connected in a structure in which the masking member moves sensitively to discharge air even with the minute movement of the float, it also has the problem of very unstable operation.

[0015] Accordingly, the ‘multifunctional air vent valve’ of Patent No. 20-0199384, the ‘air vent valve’ of Patent No. 20-0364715, the ‘air discharge valve’ of Publication No. 10-2009-0040691, and the ‘filter equipped with a vent structure’ of Patent No. 20-0481969 have been disclosed, but the aforementioned problems are still not being improved. The problem to be solved

[0017] Accordingly, the present invention has been devised to solve the problems of the aforementioned prior art, and has been completed as a technical objective with a focus on providing a detachable air vent valve that operates with a rotary slide, which stops the inflow of foreign substances into the valve and prevents water from flowing into the valve during inspection and repair, and has a structure composed of a valve part and a bolt part that is easy to attach but difficult to detach. means of solving the problem

[0019] Accordingly, the present invention provides a valve for an air vent that is detachable and operates as a rotary slide, characterized in that the valve comprises: a guide groove formed on the upper side with an inner and outer opening and a bolt portion formed on the lower side for connecting to the air vent, a tube connecting portion formed on the upper side for connecting to the air vent, a valve connecting portion formed on the upper side for connecting to the inner bolt opening of the bolt portion, a rotating pin inserted into the guide groove, and a valve portion formed on the lower side for inducing air discharge from the air vent. Effects of the invention

[0021] According to the present invention, a detachable air vent valve that operates via a rotating slide, the valve mounted on the air vent is of the slide type, allowing for easy air venting, thereby shortening the time required for initial stabilization and enhancing convenience. Furthermore, the fastening force between the bolt part and the valve part is increased by the shape of the guide groove and the configuration of the rotating pin, and the fastening force of the rotating pin can be further increased by the locking part formed in the guide groove. Additionally, when the bolt part and the valve part are combined, the upper thickness of the bolt part where the guide groove is formed is reduced, and an inclined surface is formed on the lower part of the rotating pin, making it easy to fasten the rotating pin but difficult to remove it, thereby increasing the fastening force. This is an invention with significant effects. Brief explanation of the drawing

[0024] Hereinafter, the preferred configuration and operation of the present invention for achieving the above objective in relation to the attached drawings will be described with reference to FIGS. 1 to 12 as follows.

[0026] First, the air vent valve of the present invention, which is detachable and operates with a rotary slide, is,

[0027] A valve connected to an air vent (10) that discharges air from inside a filter to the outside comprises: a bolt part (100) having a bolt through hole (110) formed inside, a guide groove (120) with an inner and outer opening formed at the top, and a screw thread (130) formed at the bottom that connects to the connection part of the air vent; a tube connecting part (220) that is fitted into the bolt through hole (110) inside the bolt part (100), has a valve through hole (210) formed inside, and has a tube connected at the top; a rotating pin (230) that is inserted into the guide groove (120); and a valve part (200) having a guide part (240) formed at the bottom that induces air discharge from the air vent.

[0029] To explain the present invention described above in more detail,

[0031] The present invention relates to a valve connected to an air vent (10) that discharges air inside a filter to the outside.

[0033] The valve (10) of the present invention consists of a bolt part (100) and a valve part (200).

[0035] The above bolt portion (100) is composed of a bolt through hole (110), a guide groove (120), and a screw thread (130).

[0037] Referring to Figures 6 and 7,

[0038] The above bolt penetration hole (110) is formed as a penetration hole inside the bolt part (100) and penetrates from the top to the bottom.

[0039] Through this, the valve part (200) is inserted, and when the valve part (200) is rotated horizontally with the configuration of the guide groove (120) and the rotating pin (230), it slides and moves up and down.

[0041] A rotating pin is inserted into this 'V' shape, and when the valve part (200) is rotated horizontally to match the shape, it slides.

[0043] The guide groove (120) is formed on the upper part of the bolt portion (100), and in the present invention, it is formed in a 'V' shape.

[0044] At one end of the above 'V' shape, a locking part (121) is formed so that the rotating pin (230) is caught so that the valve is not opened when the rotating pin (230) slides.

[0045] The above-mentioned catch portion (121) has a certain length in the horizontal direction, a certain length in the upward direction, or a certain length in the downward direction.

[0047] The inner angle of the ‘V’ shape of the above guide groove (120) is at least 70° to at most 170°.

[0048] If the angle of the aforementioned inner angle is exceeded, the rotating pin (230) may not slide, or the fixing force during sliding may be reduced or eliminated.

[0050] Referring to Fig. 8,

[0051] The upper part of the bolt portion (100) where the guide groove (120) is formed is formed as a cylinder and has a thin thickness.

[0052] The purpose is to ensure that when attaching or detaching the valve part (200), the connection is easy due to the thinness of the upper part of the bolt part (100), but the detachment is not easily achieved.

[0054] The upper thickness of the bolt portion (100) is formed to be at least 0.8mm to 1.5mm, and the gap from the upper inner side of the bolt portion (100) to the outer circumference of the valve portion (200) is 1.5mm.

[0055] The thickness and spacing mentioned above are optimal values ​​applied to the present invention, and since a margin of error may exist, the values ​​mentioned above will not be limited.

[0057] The upper part of the bolt portion (100) may be formed thinly, and the portion where the guide groove (120) is formed may be formed thicker than the upper part, or the upper part may be formed thinly and become thicker as it goes toward the portion where the guide groove (120) is formed.

[0058] By making the thickness of the part where the guide groove (120) is formed thicker than the upper part, when the valve part (200) is rotated and closed, the contact area with the rotating pin (230) is increased, thereby increasing the coupling force of the valve and preventing it from detaching even under high pressure.

[0060] The above screw thread (130) is formed on the lower part of the bolt portion (100) and is connected to the connection part of the air vent.

[0062] The threads (130) of the above bolt part (100) can be selectively used among mm threads, pt threads, or npt threads.

[0064] The above valve part (200) is composed of a valve through hole (210), a tube connection part (220), a rotating pin (230), and a guide part (240).

[0066] The above valve penetration hole (210) is formed as a penetration hole inside the valve part (200) and penetrates from the top to the bottom.

[0067] In the case of the lower part, the bottom surface is blocked, and air is drawn in through the guide part (240) and discharged to the outside through the valve penetration hole (210).

[0069] A screw-shaped discharge groove is formed in the inner circumference of the above valve penetration hole (210) to discharge air.

[0071] The above tube connection part (220) is configured on the upper part of the valve part (200), and a tube for discharging air is connected.

[0072] The above tube connection part (220) is composed of a first connection part (221) made of a cylinder and a second connection part (223) made of a square shape.

[0073] Due to the first and second fastening parts (221, 223) mentioned above, the fastening force on the tube is increased, which prevents the tube from coming off due to pressure when air is discharged.

[0075] The above-mentioned rotating pin (230) is inserted into the guide groove (120) of the above-mentioned bolt part (100) and is formed to protrude outward by a certain length.

[0076] The above-mentioned rotating pin (230) may be composed of a single pin, or on both sides, or in multiple numbers.

[0077] In the present invention, it is formed in a circular shape; however, since the shape can be varied in various ways, such as into a square shape, it will not be limited to the circular shape described above.

[0079] Referring to Fig. 5,

[0080] An inclined surface (231) is formed on the outer lower side of the above-mentioned rotating pin (230).

[0081] Due to the formation of the above-mentioned inclined surface (230), when the valve part (200) is inserted into the bolt part (100), it is possible to connect it naturally and easily.

[0082] In addition, the upper part of the rotating pin (230) is formed in a square shape so that the upper surface contacts the upper bottom surface of the guide groove (120), thereby preventing it from easily detaching.

[0084] Additionally, the inclined surface (231) can be formed in various shapes, such as being formed in a straight line, being formed in an inner curve, being formed in an outer curve, or being formed in a protruding shape with one or more protrusions, so the formation of the inclined surface (231) will not be limited.

[0086] The above-mentioned rotating pin (230) has a catch groove formed on the outer circumference of the guide groove (120).

[0087] A protrusion is formed on the upper bottom surface of the guide groove (120), and a locking groove of a certain depth is formed on the upper surface of the rotating pin (230) so that the protrusion can be inserted.

[0088] This prevents the rotating pin from coming loose.

[0090] Referring to Fig. 7,

[0091] The above-mentioned induction part (240) is formed at the lower part of the valve part (200) and induces air discharge of the air vent.

[0093] The above-mentioned guide portion (240) is located at a certain position spaced apart from the lower surface and is connected to the valve penetration hole (210), and is formed on the side.

[0095] The above-mentioned guide member (240) can have various shapes such as circular, elliptical, semicircular, or rectangular, and can form one or more guide members (240), so the shape and number of the above-mentioned guide members (240) will not be limited.

[0096] The induction part (240) used in the present invention is limited to a size of 5 mm to 20 mm.

[0098] Referring to Fig. 7,

[0099] A first insertion groove (250) is formed in the lower part of the above-mentioned rotating pin (230) into which a seal (300) surrounding the outer circumference is inserted, and

[0100] A second inlet groove (260) is formed in the lower part of the above-mentioned guide part (240) into which a seal (300) covering the outer circumference is inserted.

[0101] The above first and second inlet grooves (250, 260) are intended to prevent air from leaking between the inner circumference of the bolt through hole (110) and the outer circumference of the valve part (200) when air is discharged.

[0103] When the air discharge is opened by the rotating slide of the valve part (200), the air discharged due to the respective seals (300) inserted into the first and second inlet grooves (250, 260) is drawn into the guide part (240) according to the direction of the arrow in Fig. 7, and then discharged only through the valve through hole (210).

[0105] On the upper side of the rotating pin (230) of the valve part (200), a support part (270) is formed with an outer diameter larger than the outer diameter of the valve part (200) in which the rotating pin (230) is formed and smaller than the outer diameter of the end of the rotating pin (230).

[0106] Due to the support member, when the bolt part (100) and the valve part (200) are combined, deformation of the thin thickness portion of the bolt part (100) can be prevented.

[0107] This is intended to prevent deformation of the thin sections caused by the pressure of the discharged air.

[0109] According to the present invention as described above, the valve mounted on the air vent is of the slide type, allowing for easy air venting, thereby shortening the time required for initial stabilization and enhancing convenience. Furthermore, the fastening force between the bolt part and the valve part is increased by the shape of the guide groove and the configuration of the rotating pin, and the fastening force of the rotating pin can be further increased by the locking part formed in the guide groove. Additionally, when the bolt part and the valve part are combined, the upper thickness of the bolt part where the guide groove is formed is reduced, and an inclined surface is formed on the lower part of the rotating pin, making it easy to fasten the rotating pin but difficult to remove it, thereby increasing the fastening force. This is an invention with significant effects. Explanation of the symbols
