Description

Technical Field

[0001] This utility model relates to the field of valve technology, and in particular to an insulated gas filter. Background Art

[0002] In recent years, with the widespread use of piped gas and gas appliances, almost every household using gas has one. Gas is transported through pipes. Newly installed gas pipes may contain building debris, while older pipes may contain rust and other impurities. These impurities entering combustion appliances can pose safety hazards. Therefore, a gas filter must be installed on the gas pipe when gas enters the home. The angled filter inside the filter removes impurities from the gas, ensuring its purity.

[0003] In related technologies, existing gas filters generally use a plug-in structure to install an inclined filter screen inside the filter body. The filter screen is used to filter impurities in the gas, but it is difficult to filter out impurities such as metal shavings. The filtered gas is not pure and causes safety hazards. Utility Model Content

[0004] The present invention aims to at least partially solve the problems existing in the prior art, and for this purpose, the present invention aims to provide an insulated gas filter.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0020] The following is for reference Figure 1-3 The present invention relates to an insulated gas filter.

[0021] like Figure 1-3 As shown, an insulated gas filter according to an embodiment of the present invention includes an insulated connector 1, a magnetic filter ring 2, a filter screen 4, and a metal connector 5. The left end of the insulated connector 1 is used to connect to a gas pipeline. The magnetic filter ring 2 is installed at the right end of the insulated connector 1. The filter screen 4 is installed inside the left end of the metal connector 5. The right end of the insulated connector 1 is connected to the left end of the metal connector 5. The right end of the metal connector 5 is used to connect to a gas appliance.

[0022] It should be noted that the gas flows from the left end of the insulating connector 1 and from the right end of the metal connector 5.

[0023] Therefore, the insulating joint 1 effectively isolates static electricity and current in the gas pipeline, while the combined application of the magnetic filter ring 2 and the filter screen 4 achieves efficient filtration of the gas, resulting in purer gas. Furthermore, the simple structural design facilitates installation and disassembly, allowing for timely removal of filtered impurities.

[0024] In one embodiment, the insulating joint 1 can be made of various insulating materials. For example, it could be Plastic products Used to block static electricity and current in gas pipelines. The metal connector 5 can be made of copper or other materials required by standards. The magnetic filter ring 2 is used to adsorb and filter iron-containing impurities in the gas pipeline, such as those from construction waste and gas pipeline corrosion. The filter screen 4 can be made of stainless steel wire mesh to filter small particulate impurities. This results in purer gas filtered through the gas filter.

[0025] In one embodiment, the left end of the insulating connector 1 is provided with an external thread to facilitate connection between the insulating connector 1 and the gas pipeline. The right end of the metal connector 5 is provided with an internal thread to facilitate connection between the metal connector 5 and gas equipment.

[0026] In one embodiment, the right end of the insulating joint 1 has a mounting hole 7 with an inner diameter larger than the inner diameter of the pipe opening of the insulating joint 1, and the magnetic filter ring 2 is installed in the mounting hole 7. This facilitates the installation of the magnetic filter ring, making the magnetic filter more stable and improving the adsorption and filtration performance. The left end of the metal joint 5 has a mounting groove 8 inside, and the filter screen 4 is installed in the mounting groove 8 by a retaining ring 3. This facilitates the installation and removal of the filter screen 4, making the filter screen 4 stable after installation and improving the filtration performance.

[0027] Optionally, the right end of the insulating connector 1 is provided with an external thread, and the left end of the metal connector 5 is provided with an internal thread. The internal thread is located on the left side of the mounting groove 8. The external thread at the right end of the insulating connector 1 mates with the internal thread of the metal connector 5, and the right end of the magnetic filter ring 2 abuts against a portion of the inner wall of the metal connector 5. This facilitates the installation and disassembly of the insulating connector 1 and the metal connector 5, allowing for timely cleaning of impurities from the magnetic filter ring 2 and the filter screen 4.

[0028] Optionally, the right end of the insulating connector 1 is further provided with a limiting protrusion 6. The right end of the limiting protrusion 6 is located at the left end of the external thread on the right end of the insulating connector 1. When the insulating connector 1 and the metal connector 5 are connected, the right end of the limiting protrusion 6 abuts against the left end of the metal connector 5. This prevents over-installation and damage to the internal filter screen 4 and magnetic filter ring 2 when the insulating connector 1 and the metal connector 5 are connected together.

[0029] In one specific embodiment, when using the gas filter of this embodiment, the magnetic filter ring 2 and the filter screen 4 are respectively installed into the mounting hole 7 and the mounting groove 8. Then, the insulating connector 1 and the metal connector 5 are connected together. The insulating connector 1 is screwed into the gas pipeline, and the metal connector 5 is screwed into the pipeline of the gas equipment. The gas enters from the insulating connector 1 and passes through the magnetic filter ring 2 and the filter screen 4 in sequence. The magnetic filter ring 2 filters out the metal impurities in the gas, and the filter screen 4 filters out the unfiltered particles, thereby making the gas flowing out of the metal connector 5 purer.

[0030] Therefore, the insulated gas filter of this utility model solves the technical problem in existing related technologies that gas filters are unable to filter out impurities such as metals in gas, resulting in impure filtration. It achieves the following beneficial effects: on the one hand, the insulated joint 1 provides insulation against static electricity and current in the gas pipeline; on the other hand, the combined application of the magnetic filter ring 2 and the filter screen 4 achieves highly efficient filtration of the gas, resulting in purer filtered gas. Furthermore, the gas filter provided in this embodiment has a simple structure, is easy to install and disassemble, and allows for timely cleaning of filtered impurities.
