Description

Technical Field

[0001] The utility model relates to the technical field of angle valves, in particular to an angle valve safety device. Background Art

[0002] Angle valve is an angle stop valve, whose water inlet and water outlet are at a right angle of 90 degrees. It is used for laying pipelines and is usually used in the field of bathroom to switch internal and external water outlets. The existing angle valve mainly includes an angle valve body and a valve core installed in the first end of the angle valve body. The angle valve body has an inlet pipe and an outlet pipe that are vertically connected to each other. The inlet pipe is arranged horizontally, and a valve core seat is provided in the first end of the inlet pipe. The valve core is installed in the valve core seat, and a screw section is provided on the outer side wall of the second end of the inlet pipe. The outer side wall of the screw section is provided with an external thread. The second end of the inlet pipe has an open opening as the water inlet, and the outlet pipe is arranged upright and integrally formed with the inlet pipe. The end of the outlet pipe facing away from the inlet pipe has an open opening as the water outlet; when in use, a reserved outlet pipe is reserved on the wall, and the outlet end of the reserved outlet pipe has an internal thread. The screw section of the inlet pipe is screwed together with the internal thread of the reserved outlet pipe using raw tape to complete the installation of the angle valve.

[0003] The above-mentioned angle valve needs to be installed with raw tape during the installation process, but the raw tape is often wrapped too much or too little. When it is wrapped too much, the water outlet pipe cannot be at the predetermined angle, and when it is wrapped too little, the sealing degree between the angle valve and the outlet pipe is insufficient. Moreover, during the installation process, the screw segment often cracks due to excessive force. Due to the sealing of the raw tape, the screw segment can still discharge water normally when it is slightly broken. During continuous use, the water flow and water pressure cause the broken part to expand and break the wire, which makes it impossible to find the broken wire of the screw segment in time. Once the screw segment is broken in the wall, other tools need to be used to remove the screw segment broken in the wall. The operation is difficult, time-consuming and labor-intensive.

[0004] In view of this, the inventor of this case conducted in-depth research on the problem, which led to the creation of this case. Utility Model Content

The end of the tightening piece facing the first end of the water inlet piece has a mounting section extending outside the cylindrical section. The sealing gasket is tightened outside the mounting section and tightly fits with the end face of the cylindrical section.

[0010] The outer side wall of one end of the cylindrical section away from the horn section is provided with a convex ring with a closed ring structure, and the sealing gasket is tightly fitted with the convex ring. The outer sleeve of the cylindrical section is tightly provided with a double sealing gasket that is tightly fitted with the convex ring. The outer diameter of the convex ring, the outer diameter of the sealing gasket and the outer diameter of the double sealing gasket all coincide with the inner diameter of the reserved water outlet pipe.

[0011] The water blocking piece is a horn block that gradually shrinks from the first end of the water blocking piece to the second end of the water blocking piece, and the horn block can match the hollow chamber of the horn section.

[0013] The second end portion of the mounting rod is provided with a pressing block which is pressed against the valve core seat of the angle valve.

[0014] The tightening block includes a connecting ring body and a connecting rod. The connecting ring body is located outside the second end portion of the mounting rod. The inner diameter of the connecting ring body is larger than the outer diameter of the second end of the mounting rod. A plurality of connecting rods are provided. Each connecting rod is distributed around the circumference of the connecting ring body at intervals, and one end of the connecting rod is integrally formed with the connecting ring body, and the other end is integrally connected to the outer side wall of the second end of the mounting rod.

[0015] The mounting rod comprises a first rod body and a second rod body, the water blocking member is mounted on the first end portion of the first rod body, the second end portion of the first rod body is mounted on the second rod body in a manner that it can move horizontally along the second rod body and be confined within the second rod body, and the tightening block is located outside the second end portion of the second rod body.

The angle valve can be installed in a simple and convenient manner without the aid of raw tape to achieve the sealing fit of the angle valve. When in use, water flows from the water inlet into the water inlet pipe of the angle valve and flows out from the water outlet pipe of the angle valve. During use, if the screw section of the angle valve cracks, there is no raw tape to block it, and the water can flow out directly. The cracking of the screw section can be discovered in time, and the cracked angle valve can be taken out in time, which is convenient to operate. If the screw section of the angle valve breaks, the second end of the mounting rod is not supported by the angle valve core seat. Under the impact of the water flow, the water blocking member moves toward the second end of the water inlet member, thereby blocking the second end of the water inlet member, and the water inlet member stops discharging water, which plays the role of stopping water when the screw section breaks. In addition, the water blocking member can move horizontally in the water inlet member, thereby adjusting the water outlet pressure of the second end of the water inlet member.

[0022] In order to further explain the technical solution of the present invention, it is described in detail below with reference to the accompanying drawings.

[0023] An angle valve safety device, such as Figures 1-4As shown, the device comprises a mounting rod 1, a water inlet member 2, and a water blocking member 3. Both the mounting rod 1 and the water inlet member 2 are disposed horizontally. The water inlet member 2 comprises a water inlet chamber extending along the horizontal direction of the water inlet member 2 and penetrating both ends of the water inlet member 2. Specifically, the water inlet member 2 is a hollow cylinder with both ends open, comprising a cylindrical section 21 and a horn section 22. The horn section 22 is a hollow horn structure that tapers from the first end of the water inlet member 2 toward the second end of the water inlet member 2. During use, water flows into the water inlet chamber from the first end and then flows out from the second end.

[0024] The water blocking member 3 is located within the water inlet chamber in a manner that it can translate along the horizontal direction of the water inlet member 2. The outer diameter of the water blocking member 3 is smaller than the inner diameter of the first end of the water inlet member 2 and matches the inner diameter of the second end of the water inlet member 2. The first end of the mounting rod 1 extends into the water inlet chamber and is fixedly matched with the water blocking member 3. The second end of the mounting rod 1 is outside the second end of the water inlet member 2. The second end of the mounting rod 1 is held on the side of the angle valve core seat facing the reserved water outlet pipe. Specifically, The water blocking member 3 is in the cylindrical section 21, and the outer diameter of the water blocking member 3 is smaller than the inner diameter of the cylindrical section 21. The water blocking member 3 can be tightly fitted with the trumpet section 22, that is, the water blocking member 3 is a trumpet block that gradually shrinks from the first end of the water blocking member 3 to the second end of the water blocking member 3. The trumpet block can match the hollow chamber of the trumpet section 22, and a water flow channel is formed between the outer wall of the trumpet block and the inner wall of the trumpet section 22. Preferably, the outer side of the water blocking member 3 is recessed with an inner sealing ring 31 for embedding When the water shutoff member 3 is in the closed position, the water shutoff member 3 is in the closed position, and the second end of the water shutoff member 3 is in the closed position, and the second end of the water shutoff member 3 is in the closed position, and the second end of the water shutoff member 3 is in the closed position, and the second end of the water shutoff member 3 is in the closed position, and the second end of the water shutoff member 3 is in the closed position, and the second end of the water shutoff member 3 is in the closed position, and the second end of the water shutoff member 3 is in the closed position, and the second end of the water shutoff member 3 is in the closed position, and the second end of the water shutoff member 3 is in the closed position, and the second end of the water shutoff member 3 is in the closed position, and the second end of the water shutoff member 3 is in the closed position

[0025] The first end portion of the water inlet member 2 has a sleeve seal 4 that is tightly sleeved in the reserved water outlet pipe, and the sleeve seal 4 is provided with a water passage 100 that is connected to the water inlet chamber. The first end portion of the mounting rod 1 and the sleeve seal 4 are provided with a supporting structure 5 that supports the mounting rod 1, and the sleeve seal 4 is installed on the cylindrical section 21; specifically, the sleeve seal 4 has a sleeve tightening member 41 and a sealing gasket 42, the sleeve tightening member 41 is sleeved in the second end portion of the cylindrical section 21, and is sealed with the cylindrical section 21 through a sealing ring 411 that is tightly sleeved on the outside of the sleeve tightening member 41, that is, the sleeve tightening member 41 is a hollow cylinder with two ends open, and the outer diameter of the sleeve tightening member 41 matches the inner diameter of the cylindrical section 21, and A first groove is recessed on the outer wall of the first end of the tightening member 41, and a second groove is recessed at the position of the cylindrical section 21 corresponding to the first groove, and the sealing ring 411 is embedded in the first groove and the second groove; the central area of the tightening member 41 has a central column 51 extending in the horizontal direction of the water inlet member 2, and a plurality of connecting ribs 511 are convexly provided on the outer wall of the central column 51 and are distributed around the central column 51 and are integrally connected to the inner wall of the tightening member 41 at intervals. A channel is formed between the two connecting ribs 511, and each channel constitutes the water passage 100. The first end of the mounting rod 1 is extended with an extension rod 52 that passes through the water blocking member 3 and is movably sleeved in the central column 51, extending The rod 52 and the center column 51 constitute the support structure 5. The end of the tightening member 41 facing the first end of the water inlet member 2 has a mounting section 412 extending outside the first end of the cylindrical section 21. The sealing gasket 42 is tightly sleeved on the outside of the mounting section 412 and fits tightly with the end face of the cylindrical section 21. That is, the outer side wall of the end of the cylindrical section 21 away from the horn section 22 is protruding outward with a convex ring 211 in a closed annular structure. The sealing gasket 42 fits tightly with the convex ring 211. The outer sleeve of the cylindrical section 21 is tightly provided with a double sealing gasket 212 that fits tightly with the convex ring. The convex ring 211 is clamped between the sealing gasket 42 and the double sealing gasket 212. The outer diameter of the convex ring 211 and the outer diameter of the sealing gasket 42 are the same as the double The outer diameter of the sealing gasket 212 is consistent with the inner diameter of the reserved water outlet pipe; during assembly, the first end of the water inlet member 2 is also extended into the water inlet pipe until the double sealing gasket 212 is pressed against the second end face of the water inlet pipe. When installing the angle valve, the double sealing gasket 212, the convex ring 211 and the sealing gasket 42 are all extended into the reserved water outlet pipe, and then the screw section of the water inlet pipe is screwed into the reserved water outlet pipe to complete the installation of the angle valve. The double sealing gasket 212, the convex ring 211 and the sealing gasket 42 make the angle valve and the reserved water outlet pipe seal. There is no need to use raw tape to install the angle valve. If the screw section of the water inlet pipe cracks, water can flow out from the crack, which means that the crack of the screw section can be discovered in time.Furthermore, before inserting the water inlet pipe into the angle valve, the extension rod 52 is adjusted to move relative to the center column 51. If the extension rod 52 is moved along the second end of the water inlet member 2, it can drive the water blocking member 3 toward the second end of the water inlet member 2 and enter the range of the horn section 22, thereby adjusting the water flow channel formed between the outer wall of the water blocking member 3 and the inner wall of the horn section. The further the water blocking member 3 moves toward the second end of the water inlet member 2, the smaller the water flow channel becomes, and the greater the water pressure flowing out of the water flow channel. Conversely, the further the water blocking member 3 moves toward the first end of the water inlet member 2, the larger the water flow channel becomes, and the smaller the water pressure flowing out of the water flow channel becomes. Thus, adjusting the water blocking member 3 can regulate the water pressure of the water flowing out of the water inlet member 2. Moreover, when the water blocking member 3 completely enters the horn section 22, the water flow channel is blocked, and the second end of the water inlet member 2 is blocked. During the blockage, the inner sealing ring 31 can ensure a sealing fit between the water blocking member 3 and the horn section 22.

[0026] The first end face of the water blocking member 3 is concavely provided with an installation groove, and the outer side wall of the extension rod 52 is located at the position of the installation groove and is sleeved with a tensioning spring 521, one end of the tensioning spring 521 is connected to the bottom of the installation groove, and the other end of the tensioning spring 521 is connected to the center column 51; when in use, since the second end of the mounting rod 1 presses against the side of the angle valve core seat facing the reserved water outlet pipe, if the screw section of the water inlet pipe is broken, the second end of the mounting rod 1 cannot be held on the angle valve core seat, and at this time, the water flow impacts the water blocking member 3, and the tensioning spring moves toward the second end of the trumpet section 22 of the water inlet member 2. When the water blocking member 3 and the trumpet section 22 are tightly fitted, the second end of the water inlet member 2 is blocked and water discharge stops.

[0027] In the present invention, the angle valve safety device is applied to the angle valve. When assembling the angle valve safety device, first move the first rod 11 toward the second end of the water inlet part 2 to adjust the distance of the water blocking part 3, thereby controlling the water pressure of the water flow channel, and then extend the second rod 12 into the water inlet pipe of the angle valve, hold the tight sealing part 4 and rotate to drive the first rod 12 to rotate relative to the second rod 11, until the second end of the second rod 12 is tightly pressed against the angle valve valve core seat, and the double sealing gasket 212 is sealed with the second end face of the water inlet pipe, thus completing the assembly of the angle valve safety device; when installing the angle valve, extend the double sealing gasket 212, the convex ring 211 and the sealing gasket 42 together into the reserved water outlet pipe, and then screw the screw section of the water inlet pipe into the reserved water outlet pipe, so that the angle valve and the reserved water outlet pipe are sealed, thus completing the installation of the angle valve without the need for auxiliary The raw tape realizes the sealing fit of the angle valve, and the installation is simple and convenient. When in use, water flows from the water inlet part 2 into the water inlet pipe of the angle valve and flows out from the water outlet pipe of the angle valve. If the screw section of the angle valve cracks, there is no raw tape to block it, and the water can flow out directly. The cracking of the screw section can be discovered in time, and the cracked angle valve can be taken out in time, which is more convenient to operate. If the screw section of the angle valve breaks, the second end of the second rod body 12 is not supported by the angle valve core seat. Under the impact of the water flow, the water blocking part 3 moves toward the second end of the water inlet part 2, thereby blocking the second end of the water inlet part 2, and the water inlet part 2 stops discharging water, which plays the role of stopping water when the screw section breaks. In addition, the water blocking part 3 can move horizontally in the water inlet part 2, so as to adjust the water outlet spacing of the water flow channel at the second end of the water inlet part 2, thereby adjusting the water outlet pressure at the second end of the water inlet part 2.

[0028] Preferably, the second end portion of the mounting rod 1 has a tightening block 6 that is tightened on the angle valve core seat, and the tightening block 6 is outside the second end portion of the second rod body 12, that is, the tightening block 6 has a connecting ring body 61 and a connecting rod 62, and the connecting ring body 61 is outside the second end portion of the mounting rod 1, and the inner diameter of the connecting ring body 61 is larger than the outer diameter of the second end of the mounting rod 1, and a plurality of connecting rods 62 are provided, and each connecting rod 62 is distributed around the circumference of the connecting ring body 61 at intervals, and a water flow channel is formed between each two connecting rods 62, and one end of the connecting rod 62 is integrally formed with the connecting ring body 61, and the other end is integrally connected to the outer side wall of the second end of the mounting rod 1; when used, the tightening block 6 enables the second end portion of the mounting rod 1 to be tightened on the angle valve core seat, and the connecting ring body 61 can be tightened on the angle valve core seat more firmly than a single rod body, and does not affect the water flowing out of the valve core seat from the water flow channel into the water inlet pipe.
