Description

Technology Field

[0001] The present invention relates to a pipe-mounted angle valve, and more specifically, is configured to be connected to a cold and hot water pipe embedded in a wall and simultaneously connected to a connecting pipe that sends water supplied from the cold and hot water pipe to a faucet fitting of a washbasin or a water supply pipe of a toilet, and is configured to be screw-fastened to the connecting pipe, while simplifying the configuration of the flow control member and preventing leakage of the control valve and minimizing exposure. Background Technology

[0002] Generally, a pipe-mounted angle valve is configured with the inlet and outlet directions at a right angle to change the flow of fluid at a right angle, and is installed in cold and hot water pipes embedded in the walls of washbasins, toilets, bathrooms, kitchens, laundry rooms, etc. of a building to supply cold and hot water to faucets, fixtures, or water storage tanks of toilets.

[0003] The angle valve with a pipe attachment that performs the above-mentioned function has its inlet connected to a cold or hot water pipe connected through the interior of a building wall, and a supply hose connected to a faucet fitting of a washbasin or sink or a storage tank of a toilet connected to the outlet direction, so that water supplied from the cold or hot water pipe is supplied to the faucet fitting or the water storage tank of the toilet by rotating the operating lever on one side in the open direction, or in the case of repair or replacement work on the faucet fitting or toilet, the operating lever is rotated in the cross direction to cut off the supplied water.

[0004] A conventional angle valve of this type is configured as described in Registered Utility Model Publication No. 20-0405517, comprising a connecting pipe body having a water supply hole in the center of the interior and connected to a cold or hot water pipe, a branch pipe communicating with one side of the connecting pipe body, a spiral pipe having a connecting rod connected to the inner circumference of the front end of the connecting pipe body, an opening / closing lever part consisting of an opening / closing plate with a sealing rubber attached to it so as to be positioned at the rear end of the spiral pipe to open and close the water supply hole, and a finishing cap connected to the connecting pipe body with the front end of the connecting rod passing through it.

[0005] However, the above angle valve has a connecting rod that protrudes further outward from the end cap, and the opening / closing lever is secured using a fixing screw. Since the opening / closing lever is always exposed outward from the angle valve, it detracts from the aesthetics and increases the number of parts, assembly labor, and costs, which leads to a decrease in product competitiveness.

[0006] In addition, since the pitch of the spiral tube in the opening / closing lever section and the pitch of the spiral tube in the connecting pipe section were identical or similar, the connecting pipe section and the end cap came loose during the operation of the opening / closing lever, causing leakage. This resulted in the user having trouble operating the opening / closing lever and increased working time.

[0007] In addition, if the packing material inside the end cap remains in surface contact with the connecting rod for a long period, it hardens and becomes fixed to the connecting rod, requiring more force to rotate the connecting rod during the operation of the opening / closing lever; in severe cases, this can lead to the packing material breaking and causing leakage. Prior art literature

[0008] Republic of Korea Registered Utility Model Publication No. 20-0405517 Angle valve for pipe fitting (Registration date: January 2, 2006) The problem to be solved

[0010] In addition, the present invention aims to provide a pipe-attached angle valve configured to control the flow rate by forming the pitch of the control shaft screw of the flow control member longer than the screw pitch of the valve body, thereby increasing the forward and backward movement length through the rotational movement of the flow control shaft.

[0011] In addition, the present invention aims to provide a pipe-mounted angle valve that allows a user to easily operate a flow control member assembled in a valve body, minimizes external exposure to enhance aesthetic appeal, and prevents leakage by elastically supporting a flow control shaft in a packing member. means of solving the problem

[0018] In addition, the tool fitting groove (38) can be formed to have one of the shapes of a straight groove, a cross groove, a polygonal wrench groove, and a star wrench groove.

[0019] Additionally, the control shaft blocking member (39) is further provided with a guide protrusion (39a) that is supported in contact with the fluid movement surface (24) formed on the inner diameter surface of the shaft insertion member (25), so that the flow control shaft (31) can be configured such that the control part (31b) on one side is supported by the shaft contact part (47) of the control shaft packing member (40), and the blocking part (31a) on the other side is supported by the guide protrusion (39a) on the fluid movement surface (24), thereby allowing the flow control shaft (31) to move horizontally.

[0020] In addition, the control shaft screw (35) of the flow control shaft (31) and the shaft assembly screw (26) of the valve body (20) are formed to have a longer pitch than the thread pitch of the inlet (21) connected to the cold and hot water pipe (1), so that the flow control shaft (31) can be configured to rotate with relatively little force.

[0027] The pipe-attached angle valve of the present invention is configured to be connected to a cold and hot water pipe embedded in a wall, and simultaneously to be screw-fastened to a connecting pipe for sending water supplied from the cold and hot water pipe to a faucet fitting of a washbasin or a water supply pipe of a toilet, and is invented to simplify the configuration of the flow control member while preventing leakage of the control valve and minimizing exposure.

[0028] The present invention is capable of various modifications and may take various forms, and embodiments are to be described in detail in the text. However, this is not intended to limit the present invention to the specific disclosed forms, and it should be understood that it includes all modifications, equivalents, and substitutions that fall within the spirit and scope of the invention.

[0029] Hereinafter, the features of the configuration of the pipe-attached angle valve (10) according to the present invention can be understood through embodiments described in detail with reference to the attached drawings.

[0030] First, as shown in FIGS. 1 to 5, the angle valve of the present invention is a valve for changing the direction of fluid flow by 90 degrees, and a flow path connecting an inlet (21) and an outlet (23) is formed inside the valve body (20). A packing fixing nut (50) including a flow rate control member (30) and a control shaft packing member (40) is fastened to the shaft insertion port (25) on the other side of the valve body (20), and is configured to open or close the flow path connecting the inlet (21) and the outlet (23) by the movement of the flow rate control member (30).

[0031] To this end, the valve body (20) has a hollow tube shape and an inlet (21) connected to a cold or hot water pipe (1) is formed at one end, and an outlet (23) is provided in the center that is assembled with a connecting pipe (3) for sending water to a faucet fitting of a washbasin or a water supply pipe of a toilet, and a shaft assembly screw (26) and a fluid movement surface (24) are formed on the inner circumference of the shaft insertion opening (25) at the other end.

[0032] At this time, a partition wall is formed with a flow path passage hole (22) offset in the direction of the inlet (21) of the valve body (20), a fluid passage surface (24) is provided between the partition wall and the shaft assembly screw (26), and it is natural that screw threads are formed on the outer circumference of the inlet, the discharge port and the shaft insertion port so that a nut can be fastened.

[0033] The valve body (20) of the present invention is configured such that an inlet and a shaft insertion port are formed in a horizontal direction, and a discharge port is branched vertically in the middle thereof. Since the shape of the valve body can be applied in various ways according to the requirements of industry professionals, it is not limited to a specific shape.

[0034] And a flow control member (30) is inserted into the shaft insertion port (25) of the valve body (20), and a control shaft screw (35) formed on the outer circumference of the flow control member (30) is connected to a shaft assembly screw (26) formed on the inner circumference of the shaft insertion port (25) and is configured to move forward or backward to open and close the flow path moving hole (22) of the inlet port (21).

[0035] The above flow control member (30) has a control shaft screw (35) protruding from one side of a flow control shaft (31) having a cylindrical shape, so as to divide the control shaft screw (35) into a blocking part (31a) and an adjustment part (31b), and a control shaft blocking member (39) formed of an elastic material with good adhesion, such as rubber or urethane, is coupled to one end of the blocking part (31a).

[0036] Additionally, the above flow control member (30) can have a control shaft screw (35) fastened to the shaft assembly screw (26) of the shaft insertion port (25), and a tool inserted into the tool fitting groove (38) formed in intaglio on the front end surface of the control part (31b) to rotate the flow control shaft (31), thereby allowing the control shaft blocker (39) to open or close the flow path movement hole (22) of the valve body (20).

[0037] Accordingly, as shown in FIG. 4, when the flow control shaft (31) is rotated to a closed state and moved horizontally to the left in the drawing, the control shaft blocker (39) closes the flow path moving hole (22), preventing the fluid supplied through the inlet (21) from moving to the outlet (23), and the adjustment part (31b) of the flow control shaft (31) has only the tool fitting groove (38) exposed to the outside from the center of the packing fixing nut (50), so that the user can immediately recognize the open / closed state of the angle valve (10) and the fluid movement, thereby increasing aesthetic appeal.

[0038] Also, as shown in Fig. 5, when the flow control shaft (31) is rotated in an open state and moved horizontally to the right in the drawing, the adjustment part (31b) of the flow control shaft (31) rotates simply according to the pitch length of the control shaft screw (35), supplying fluid through the connected flow path between the inlet (21) and the outlet (23), and is hermetically supported by the shaft contact part (47) of the control shaft packing member (40) to prevent leakage.

[0039] Here, the tool fitting groove (38) formed on the front of the adjustment part (31b) to rotate the flow control shaft (31) may be formed into a straight groove or a cross groove so that the flow control shaft (31) can be rotated using a plate material such as a coin, as shown in FIG. 6, or formed into a triangular, hexagonal, or star-shaped groove so that the flow control shaft can be rotated using a wrench corresponding to the shape, and this configuration may also be included in the present invention.

[0040] In addition, it should be noted that the present invention may also include chamfering a portion of the outer circumference of the tip of the adjustment part (31b), processing or forming it into a shape selected from a triangle or a hexagon so that it can be rotated using a tool, processing irregularities such as splines and knurling so that a user can easily grip and rotate it, or assembling a tube for anti-slip purposes to improve airtightness with the shaft contact part (47).

[0041] In addition, in the present invention, the control shaft screw (35) of the flow control shaft (31) and the shaft assembly screw (26) of the valve body (20) are formed to have a longer pitch than the thread pitch of the inlet (21) connected to the cold and hot water pipe (1), so that when the flow control shaft (31) is rotated once, it moves horizontally a longer distance, allowing the flow path moving hole (22) of the valve body (20) to be opened and closed quickly.

[0042] Additionally, if the diameter of the blocking part (31a) is formed larger than the diameter of the adjusting part (31b) of the flow control shaft (31), the inner diameter of the shaft insertion opening (25) is formed to have a diameter through which the blocking part can pass, and the screw tip of the adjusting shaft screw (35) is fastened to the shaft assembly screw (26), thereby allowing the flow control shaft (31) to be fastened and moved with relatively little force, thereby improving ease of operation.

[0043] And on the side of the shaft insertion port (25), a control shaft packing member (40) having an elastic material such as rubber or urethane and a packing fixing nut (50) are disposed, and when the packing fixing nut (50) is fastened on the side of the shaft insertion port (25), the inner control shaft packing member (40) is pressed and compressed and supported on the side of the shaft insertion port (25) and the adjustment part (31b) of the flow control shaft (31).

[0044] The above-mentioned control shaft packing member (40) is formed with a '⊃' shape in the drawing, and a nut contact portion (41) that is inserted into and contacts the packing fitting groove (51) of the packing fixing nut (50) is formed on the right outer surface of the drawing, and a body contact portion (43) that contacts the side of the shaft insertion opening (25) of the valve body (20) is provided on the left outer surface of the drawing, and a shaft contact portion (47) is integrally formed on the inner circumference of the body contact portion (43) with a resilient groove (45), so that the shaft contact portion (47) can be supported with resilience on the outer circumference of the flow control shaft (31).

[0045] In addition, as shown in FIG. 7, the above-mentioned control shaft packing member (40) is configured such that at least one sealing ring (48) is further formed protruding from the inner circumference of the shaft contact portion (47), and the inner diameter surface of the sealing ring (48) is in line contact with the flow control shaft (31), thereby preventing water leakage inside the flow path even during horizontal movement caused by the rotation of the flow control shaft (31).

[0046] In addition, as an embodiment of the present invention, as shown in FIG. 8, a guide protrusion (39a) is further formed to protrude stepwise at the tip of the control shaft blocking member (39) in contact with the fluid movement surface (24) formed on the inner diameter surface of the shaft insertion member (25), so that the guide protrusion (39a) can prevent the flow of the blocking member (31a) during the horizontal movement of the flow control shaft (31), and the control shaft packing member (40) can prevent the flow of the adjustment member (31b), thereby enabling the flow control shaft (31) to move more stably horizontally. This configuration is also included in the present invention.

[0047] That is, the flow control shaft (31) of the present invention is connected to the shaft assembly screw (26) of the valve body (20) by a control shaft screw (35), and the adjustment part (31b) on one side is supported by the shaft contact part (47) of the control shaft packing member (40), and the blocking part (31a) on the other side is supported by the guide protrusion (39a) on the fluid movement surface (24), so that the flow control shaft (31) can move horizontally and the connection of the flow control shaft (31) can be easily achieved.

[0048] As described above, the embodiments explained are the most preferred examples of the present invention, but are not limited to the above embodiments. It is obvious to those skilled in the art that various modifications are possible within the scope of the technical spirit of the present invention. Explanation of the symbols
