Description

Technical Field

[0001] This utility model relates to the field of angle valve technology, specifically to an angle valve body with adjustable length. Background Technology

[0002] An angle valve is a type of angle gate valve. Similar to a ball valve, its structure and characteristics are modified from those of a ball valve. The difference lies in the fact that the outlet and inlet of an angle valve form a 90-degree angle. Angle valves are also called triangular valves, angle valves, or bend valves. This is because the pipe forms a 90-degree bend at the angle valve, hence the name. As an important component in household and industrial piping systems, angle valves are mainly used to control water flow, regulate water pressure, and connect pipes to bathroom fixtures (such as faucets, toilets, and washing machines).

[0003] However, since traditional angle valves are usually manufactured in one piece using forging or casting processes, the inlet or outlet pipes of the angle valve are of fixed length, and the length of the inlet or outlet pipes cannot be adjusted according to consumer needs, resulting in a relatively limited range of applications. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing an angle valve body with adjustable length.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable length angle valve body, comprising a valve body, a valve core hole disposed on the valve body for installing a valve core, an outlet pipe disposed on the valve body and connected to the valve core hole, an inlet pipe disposed on the valve body and connected to the valve core hole, and further comprising an extension pipe slidably disposed on the outlet pipe or the inlet pipe through a sliding opening, and a sealing ring disposed between the outlet pipe and the extension pipe, or between the inlet pipe and the extension pipe, for sealing the gap between the extension pipe and the outlet pipe or the inlet pipe and increasing the sliding resistance of the extension pipe on the outlet pipe or the inlet pipe when the extension pipe is installed on the outlet pipe or the inlet pipe.

[0006] A further improvement is that the extension tube is slidably mounted on the outlet pipe through a sliding opening, the inlet pipe and the extension tube are respectively provided with external threaded surfaces, and the sealing ring is provided on the outlet pipe.

[0007] A further improvement is that the water outlet pipe is provided with an installation ring groove for installing the sealing ring and for limiting the sealing ring after installation.

[0008] A further improvement is that the extension tube is slidably mounted on the inlet pipe through a sliding opening, the outlet pipe and the extension tube are provided with external threaded surfaces, and the sealing ring is provided on the inlet pipe.

[0009] A further improvement is that the water inlet pipe is provided with an installation ring groove for installing the sealing ring and for limiting the position of the sealing ring.

[0010] A further improvement is that a threaded through hole is provided on the side end face of the extension tube, and a push rod is threadedly connected to the extension tube inside the threaded through hole.

[0011] A further improvement is that the push rod is provided with a pressing tip.

[0012] A further improvement is that the abutment rod has a drive hole for inserting a tool to rotate it.

[0013] A further improvement is that the extension tube is provided with a compression inner hole for pressing the sealing ring to further increase the sliding resistance of the extension tube when the extension tube is installed on the water outlet pipe or water inlet pipe. The compression inner hole is clearance-fitted with the water inlet pipe. The diameter of the compression inner hole is smaller than the diameter of the sliding opening. The compression inner hole is connected to the sliding opening and is located at the lower end of the sliding opening.

[0014] A further improvement is that the chamfered surface on the extension tube, located between the upper end of the compression inner hole and the lower end of the sliding opening, facilitates the entry of the sealing ring into the compression inner hole when the extension tube is installed on the water outlet or water inlet pipe.

[0015] A further improvement is that a limiting ring groove is formed on the extension tube.

[0016] After adopting the above technical solution, the beneficial effects of this utility model are as follows: When assembling the valve body, the extension tube is installed on the outlet pipe or inlet pipe. When the consumer needs to adjust the length of the outlet pipe or inlet pipe, they only need to pull the extension tube to extend or retract on the outlet pipe or inlet pipe to adjust the length of the inlet pipe or outlet pipe. The gap between the extension tube and the outlet pipe or inlet pipe is sealed by the sealing ring, and the sliding resistance of the extension tube on the outlet pipe or inlet pipe is increased, thereby slightly fixing the extension length of the extension tube. The length of the inlet pipe or outlet pipe can be adjusted according to the consumer's needs, making it more versatile in use. Attached Figure Description

[0020] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. Example 1

[0021] See Figures 1 to 3 As shown, the technical solution adopted in this specific embodiment is: an adjustable-length angle valve body, including a valve body 1, a valve core hole 2 for installing a valve core on the valve body 1, an outlet pipe 3 on the valve body 1 and connected to the valve core hole 2, and an inlet pipe 4 on the valve body 1 and connected to the valve core hole 2. It also includes an extension pipe 5 slidably mounted on the inlet pipe 4 through a sliding opening 16, and a sealing ring 6 positioned between the inlet pipe 4 and the extension pipe 5 to seal the gap between the extension pipe 5 and the inlet pipe 4 and to increase the sliding resistance of the extension pipe 5 on the inlet pipe 4 when the extension pipe 5 is installed on the inlet pipe 4. A thread (not shown in the figure) is provided on the valve core hole 2 for threaded connection with the valve core. To facilitate the connection of the extension pipe 5, two parallel cuts (not shown in the figure) are provided on the outer wall of the extension pipe 5 for clamping with a wrench.

[0022] The inlet pipe 4 and the extension pipe 5 are respectively provided with external threaded surfaces 7, and the sealing ring 6 is provided on the outlet pipe 3. The external threaded surfaces 7 are provided to allow the outlet pipe 3 and the extension pipe 5 to be fixedly connected to an external water pipe with a threaded surface or to a water outlet end on the wall.

[0023] The water inlet pipe 4 is provided with an installation ring groove 8 for installing and limiting the sealing ring 6. The installation ring groove 8 can prevent the sealing ring 6 from slipping between the extension pipe 5 and the water inlet pipe 4 when the extension pipe 5 slides on the water inlet pipe 4.

[0024] The extension tube 5 has a threaded through hole 9 on its side end face, and a push rod 10 is threadedly connected to the extension tube 5 inside the threaded through hole 9.

[0025] The push rod 10 is provided with a pressing tip 11. When the push rod 10 presses against the outer wall of the water inlet pipe 4, the pressing tip 11 presses against the outer wall of the water inlet pipe 4, which can further increase the sliding resistance of the extension pipe 5.

[0026] The abutment rod 10 has a drive hole 12 for inserting a tool to rotate it. The drive hole 12 is an internal hexagonal hole, a Phillips head hole, or a flathead hole, allowing an external hexagonal wrench, a Phillips head screwdriver, or a flathead screwdriver to rotate the abutment rod 10. The pressing tip 11 is located at one end of the abutment rod 10, and the drive hole 12 is located at the other end of the abutment rod 10.

[0027] The extension tube 5 has a compression inner hole 13 for tightening the sealing ring 6 to further increase the sliding resistance of the extension tube 5 when it is installed on the water inlet pipe 4. The compression inner hole 13 is clearance-fitted with the water inlet pipe 4. The diameter of the compression inner hole 13 is smaller than the diameter of the sliding opening 16. The compression inner hole 13 is connected to the sliding opening 16 and is located at the lower end of the sliding opening 16. The diameter of the compression inner hole 13 differs from the diameter of the sliding opening 16 by 0.05-0.2 mm.

[0028] The chamfered surface 14 on the extension tube 5, located between the upper end of the compression inner hole 13 and the lower end of the sliding opening 16, facilitates the entry of the sealing ring 6 into the compression inner hole 13 when the extension tube 5 is installed into the water inlet pipe 4. The chamfered surface 14 can be an inclined chamfered surface 14 or a rounded chamfered surface 14. The chamfered surface 14 is located at the upper middle position of the extension tube 5.

[0029] The extension tube 5 has a limiting annular groove 15. After the extension tube 5 is pulled out of the water inlet pipe 4 for a certain length, the limiting annular groove 15 corresponds to the position of the sealing ring 6. At this time, the sealing ring 6 will be stuck on the limiting annular groove 15, thereby forming a stretching resistance to remind the operator that the extension length is about to reach the limit and to prevent excessive stretching from causing the extension tube 5 to detach from the water inlet pipe 4.

[0030] The limiting annular groove 15 is located at the upper middle position of the extension tube 5. The limiting annular groove 15 is as follows: Figure 3 The rectangular annular groove shown is a ring-shaped groove with right-angled sides at the top and bottom ends. The height of the limiting annular groove 15 is the same as or similar to the diameter of the sealing ring 6.

[0031] The working principle of this utility model is as follows: When assembling the valve body, the extension tube 5 is installed on the inlet pipe 4. When the consumer needs to adjust the length of the inlet pipe 4, simply pull the extension tube 5 to extend or retract on the inlet pipe 4 to adjust the length of the inlet pipe 4 or the outlet pipe 3. The gap between the extension tube 5 and the inlet pipe 4 is sealed by the sealing ring 6, which increases the sliding resistance of the extension tube 5 on the inlet pipe 4, thereby slightly fixing the extension length of the extension tube 5. When it is necessary to fix the extension tube 5 on the inlet pipe 4, a tool is inserted into the drive hole 12 and turned in the forward direction, thereby driving the push rod 10 to rotate in the threaded through hole 9 and move closer to the outer wall of the inlet pipe 4 until the push rod 10 is pressed against the outer wall of the inlet pipe 4, thereby increasing the sliding resistance of the extension tube 5 on the inlet pipe 4, thereby fixing the position of the extension tube 5. The length of the inlet pipe 4 can be adjusted according to the consumer's needs, making it versatile in use. Example 2

A thread (not shown in the figure) is provided on the valve core hole 2 for threaded connection with the valve core. To facilitate the connection of the extension pipe 5, two parallel cuts (not shown in the figure) are provided on the outer wall of the extension pipe 5 for clamping with a wrench.

[0033] The inlet pipe 4 and the extension pipe 5 are respectively provided with external threaded surfaces 7, and the sealing ring 6 is provided on the outlet pipe 3. The external threaded surfaces 7 are provided to allow the outlet pipe 3 and the extension pipe 5 to be fixedly connected to an external water pipe with a threaded surface or to a water outlet end on the wall.

[0034] The water outlet pipe 3 is provided with an installation ring groove 8 for installing the sealing ring 6 and for limiting the sealing ring 6 after installation. The installation ring groove 8 is provided to prevent the sealing ring 6 from slipping between the extension pipe 5 and the water outlet pipe 3 when the extension pipe 5 slides on the water outlet pipe 3.

[0035] The extension tube 5 has a threaded through hole 9 on its side end face, and a push rod 10 is threadedly connected to the extension tube 5 inside the threaded through hole 9.

[0036] The push rod 10 is provided with a pressing tip 11. When the push rod 10 presses against the outer wall of the water outlet pipe 3, the pressing tip 11 presses against the outer wall of the water outlet pipe 3, which can further increase the sliding resistance of the extension pipe 5.

[0037] The abutment rod 10 has a drive hole 12 for inserting a tool to rotate it. The drive hole 12 is an internal hexagonal hole, a Phillips head hole, or a flathead hole, allowing an external hexagonal wrench, a Phillips head screwdriver, or a flathead screwdriver to rotate the abutment rod 10. The pressing tip 11 is located at one end of the abutment rod 10, and the drive hole 12 is located at the other end of the abutment rod 10.

[0038] The extension pipe 5 has a compression inner hole 13 for tightening the sealing ring 6 to further increase the sliding resistance of the extension pipe 5 when it is installed on the outlet pipe 3. The compression inner hole 13 is clearance-fitted with the inlet pipe 4. The diameter of the compression inner hole 13 is smaller than the diameter of the sliding opening 16. The compression inner hole 13 is connected to the sliding opening 16 and is located at the lower end of the sliding opening 16. The diameter of the compression inner hole 13 differs from the diameter of the sliding opening 16 by 0.05-0.2 mm.

[0039] The chamfered surface 14 on the extension tube 5, located between the upper end of the compression inner hole 13 and the lower end of the sliding opening 16, facilitates the entry of the sealing ring 6 into the compression inner hole 13 when the extension tube 5 is installed into the water outlet pipe 3. The chamfered surface 14 can be an inclined chamfered surface 14 or a rounded chamfered surface 14. The chamfered surface 14 is located at the upper middle position of the extension tube 5.

[0040] The extension tube 5 has a limiting annular groove 15. After the extension tube 5 is pulled out of the outlet pipe 3 to a certain length, the limiting annular groove 15 corresponds to the position of the sealing ring 6. At this time, the sealing ring 6 will be stuck on the limiting annular groove 15, thereby forming a stretching resistance to remind the operator that the extension length is about to reach the limit and to prevent excessive stretching from causing the extension tube 5 to detach from the outlet pipe 3.

[0041] The limiting annular groove 15 is located at the upper middle position of the extension tube 5. The limiting annular groove 15 is as follows: Figure 5 The rectangular annular groove shown is a ring-shaped groove with right-angled sides at the top and bottom ends. The height of the limiting annular groove 15 is the same as or similar to the diameter of the sealing ring 6.

[0042] The working principle of this utility model is as follows: When assembling the valve body, the extension tube 5 is installed on the outlet pipe 3. When the consumer needs to adjust the length of the outlet pipe 3, simply pull the extension tube 5 to extend or retract on the outlet pipe 3 to adjust the length of the inlet pipe 4 or the outlet pipe 3. The gap between the extension tube 5 and the outlet pipe 3 is sealed by the sealing ring 6, which increases the sliding resistance of the extension tube 5 on the outlet pipe 3, thereby slightly fixing the extension length of the extension tube 5. When it is necessary to fix the extension tube 5 on the outlet pipe 3, a tool is inserted into the drive hole 12 and turned in the forward direction, thereby driving the push rod 10 to rotate in the threaded through hole 9 and move closer to the outer wall of the outlet pipe 3 until the push rod 10 is pressed against the outer wall of the outlet pipe 3 to increase the sliding resistance of the extension tube 5 on the outlet pipe 3, thereby fixing the position of the extension tube 5. The length of the outlet pipe 3 can be adjusted according to the consumer's needs, making it quite versatile.
