Description

Technical Field

[0001] The utility model relates to the technical field of pipe joints, in particular to a locking speed regulating pipe joint. Background Art

[0002] Pipe fittings are components that connect two pipes in a pipe or piping system. They are usually used when the pipe needs to be expanded, connected or repaired. There are many types of pipe fittings, including threaded fittings, welded fittings and pressure fittings. Threaded fittings connect pipes through threads and are often used in low-pressure or non-sealed applications.

[0003] A pipe joint as disclosed in CN106678463B, wherein the beneficial effects of the invention are as follows: a second observation hole is provided on the ferrule, and a first observation hole is provided on the clamping ring, so as to better judge whether the pipe is installed in place, and to facilitate the adjustment of the pipe that is not installed in place, thereby reducing the scrap rate when the pipe joint is connected. A convex ring is provided on the connecting portion of the joint body, and a protrusion is provided on the clamping ring, which is beneficial to the axial limitation of the clamping ring, reduces the axial movement of the clamping ring, the ferrule and the pipe during installation and fixing, and enables the pipe to be installed accurately in place, thereby reducing the scrap rate. An abutment ring is provided to accurately position the pipe. A boss is provided on the clamping ring and a convex edge is provided on the clamping ring, so that the inner end of the clamping ring is limited in the groove, and the axial movement of the clamping ring on the connecting portion is limited, which is beneficial to reducing the scrap rate. Arranging multiple observation holes 1 on the circumference of the clamp ring and multiple observation holes 2 on the circumference of the ferrule is conducive to judging whether the pipe is installed in place on the circumference, which is conducive to reducing the scrap rate; however, the pipe joint in the above patent does not have a speed regulation function. In some scenarios, it is necessary to adjust the flow rate of the liquid or gas in the pipeline system. If the speed cannot be adjusted, it may cause flow rate mismatch, and the fixed flow rate may cause energy waste. When the actual workload is small, the pipeline system running at a fixed speed will consume more energy, resulting in unnecessary increase in energy consumption; secondly, the above patent does not have a self-locking function, which may have some potential problems. Under certain conditions, the pipe joint may be easy to loosen or fall off, thereby increasing the risk of leakage, seepage or breakage of the pipeline system, which may cause equipment damage, leakage of harmful substances or even accidents;

[0004] Therefore, there is an urgent need for a lockable speed regulating pipe joint to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a locking speed regulating pipe joint, which includes the use of a release ring, a copper sleeve, a retaining spring, a pressure ring and a two-way sealing ring. When connecting the pipeline, the pipeline can be firmly clamped to ensure that the connection does not leak. This structural design can provide reliable stability and avoid the leakage of liquid or gas, thereby improving the safety of the pipeline system, thereby solving the problems in the background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a locking speed regulating pipe joint, comprising a release ring, a copper sleeve is arranged on the left side of the release ring surface, a retaining spring is arranged on the left side of the release ring and in the inner cavity of the copper sleeve, a pressure ring is arranged through the left side of the inner cavity of the copper sleeve, a two-way sealing ring is arranged on the left side of the pressure ring, a plastic body is arranged on the surfaces of the copper sleeve, an adjusting cap is threadedly connected to the top of the surface of the plastic body, a valve stem is fixedly connected to the bottom of the adjusting cap, the valve stem is located in the inner cavity of the plastic body and is movably connected to the plastic body, an O-ring is sleeved on the bottom of the valve stem surface, a valve body is sleeved on the surface of the plastic body, a valve core is arranged in the inner cavity of the valve body, and the bottom of the valve stem extends to the inner cavity of the valve core, and a one-way sealing ring and a support seat are arranged on the surface of the valve core in sequence from bottom to top.

[0007] Furthermore, an O-ring 2 is sleeved on the bottom of the surface of the plastic body, and the surface of the O-ring 2 is in contact with the valve body.

[0008] Furthermore, an external thread is provided at the bottom of the valve body surface, and an O-ring three is sleeved at the bottom of the valve body surface and above the external thread.

[0009] Furthermore, the surface of the adjusting cap is provided with anti-slip patterns.

[0010] Furthermore, the bottom of the plastic body is arranged as an open structure, the bottom of the valve body is arranged as an open structure, and the plastic body and the valve body are connected.

[0011] Furthermore, a slope is provided at the bottom of the valve stem surface, and the slope is used in conjunction with the valve core.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] The utility model provides a locking speed-adjusting pipe joint, which has speed-adjusting and self-locking functions and has many advantages. In actual use, by using the cooperation of the release ring, the copper sleeve, the retaining spring, the pressure ring and the two-way sealing ring and other components, when connecting the pipe, the pipe can be firmly clamped to ensure that the connection does not leak. This structural design can provide reliable stability and avoid the leakage of liquid or gas, thereby improving the safety of the pipeline system.

[0014] Secondly, when the plastic body, valve stem, O-ring, valve body, valve core, support seat and one-way sealing ring are used together, the flow rate of the pipe joint can be adjusted during operation. By adjusting the state of the matching parts, the passing speed of the fluid or gas can be controlled to meet the actual work needs;

[0015] In summary, pipe fittings with adjustable speed and self-locking functions have obvious advantages in pipeline connection. Through reasonable structural design and coordinated components, they achieve a firm connection, ensure no leakage, and provide the flexibility to adjust the flow rate. This type of pipe fitting also has an automatic locking function to avoid accidental loosening or falling off, ensuring the safe operation of the pipeline system. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The bottom of the plastic body 7 is sleeved with an O-ring 10, and the surface of the O-ring 10 is in contact with the valve body 11; the setting of the O-ring 10 achieves sealing performance between the plastic body 7 and the valve body 11, thereby preventing liquid and gas leakage.

[0026] An external thread 16 is provided at the bottom of the surface of the valve body 11, and an O-ring 3 15 is sleeved at the bottom of the surface of the valve body 11 and above the external thread 16; by using the external thread 16 and the O-ring 3 15 in combination, it is convenient to connect the valve body 11 to an external pipeline, and then the O-ring 3 15 can be used to provide sealing between the external pipeline and the valve body 11.

[0027] The surface of the adjusting cap 6 is provided with anti-skid patterns 17 ; the provision of the anti-skid patterns 17 facilitates the rotation of the adjusting cap 6 , thereby achieving the purpose of saving time and effort.
