Description

Technical Field

[0001] This utility model belongs to the field of exhaust valve installation technology, and in particular relates to an exhaust valve seat. Background Technology

[0002] Air vents are key devices in pipeline systems used to automatically remove air and prevent air blockage and cavitation. They are widely used in water supply, heating, chemical, and fire protection industries. Their core function is to automatically release air through physical or mechanical structures while preventing media leakage.

[0003] When installing an exhaust valve on existing pipelines, a valve seat is required to connect it to the exhaust valve. As the name suggests, the valve seat is a mounting base for installing the exhaust valve. Existing valve seats are simple connecting seats welded onto the pipeline, which do not have a filtering function. As a result, impurities and debris in the pipeline can easily enter the exhaust valve during exhaust, which can easily cause wear on the inner cavity of the exhaust valve, thus affecting the sealing effect after exhaust and making leakage more likely. It is also not convenient to use a filter assembly to filter impurities. Therefore, we propose an exhaust valve seat. Summary of the Invention

[0004] In view of this, the present invention aims to provide an exhaust valve seat to solve the technical problem of the inconvenience of using a filter assembly to filter impurities.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] An exhaust valve seat includes a fixed housing, a fixed pipe fixedly connected to the bottom of the fixed housing, a connecting plate fixedly fitted to the tail end of the fixed pipe, and a connecting pipe fixedly connected to the upper side of one side wall of the fixed housing. It also includes a filter assembly, a threaded hole formed at the top of the fixed housing, the filter assembly being inserted into the threaded hole, the filter assembly including a conical filter cylinder, a cross plate fixedly connected to the top of the conical filter cylinder, a threaded block connected to the top of the cross plate via a connector, the threaded block engaging with the threaded hole, and an end plate fixedly connected to the top of the threaded block.

[0007] It should be understood that the connecting plate and the pipe are connected first, then the connecting pipe and the exhaust valve are connected. When exhaust is required, the gas enters the inner cavity of the fixed shell through the fixed pipe, where the conical filter cylinder filters impurities. This helps prevent impurities from entering the exhaust valve and causing wear on the inner wall of the exhaust valve under the influence of the gas, thus extending the service life of the exhaust valve. Furthermore, when impurities adhere to the conical filter cylinder during filtration, they can move to both sides along its inclined surface under the action of the gas, thus preventing impurities from accumulating on the conical filter cylinder and affecting the exhaust effect. This helps extend the service life of the conical filter cylinder after a single cleaning and reduces the cleaning frequency. Moreover, the conical filter cylinder is inserted into the top of the fixed shell, allowing the rotating block to separate the threaded block and the threaded hole, making it easy to disassemble and clean the conical filter cylinder without disassembling the exhaust valve, which improves the convenience of cleaning.

[0008] Furthermore, the connector includes a sleeve, the tail end of which is fixedly connected to the top middle of the cross plate, a matching insert rod is inserted into the inner cavity of the sleeve, a first magnet is fixedly connected to the tail end of the insert rod, and a second magnet is fixedly installed at the bottom of the inner cavity of the sleeve.

[0009] It should be noted that by using the first and second magnets to attract the tube, the sleeve can be stably fitted onto the insert rod. When disassembling the conical filter cylinder for cleaning or replacement, the first and second magnets can be separated by pulling the conical filter cylinder, thus allowing the conical filter cylinder to be directly removed. This further improves the convenience of cleaning. Furthermore, when the conical filter cylinder is damaged, it is not necessary to replace the entire filter assembly; only the conical filter cylinder needs to be replaced, which helps reduce maintenance costs.

[0010] Furthermore, the inner cavity of the fixed shell is integrally formed with a circular step, and the outer diameter of the circular step is the same as the outer diameter of the top of the conical filter cylinder.

[0011] Specifically, the circular step design allows the conical filter cylinder to overlap on the circular step after being inserted into the inner cavity of the fixed shell, thus achieving a close fit. This helps improve the stability of the conical filter cylinder during use and also helps prevent gaps from allowing impurities to pass through.

[0012] Furthermore, the outer wall of the connecting plate is provided with multiple connecting holes, which are evenly distributed in a circular pattern on the top of the connecting plate.

[0013] Furthermore, a rotating block is fixedly connected to the top of the end plate, and the top of the rotating block is provided with an internal hexagonal groove.

[0014] Furthermore, the inner wall of the outer end of the connecting pipe is provided with an internal thread.

[0015] Compared with the prior art, the exhaust valve seat of this utility model has the following beneficial effects:

[0016] The exhaust valve seat of this utility model has a filter component installed in the inner cavity of the fixed shell. When the exhaust valve is connected for use, the filter component can filter impurities, which helps to prevent impurities from entering the exhaust valve under the influence of gas and causing wear on the inner wall of the exhaust valve, thereby extending the service life of the exhaust valve.

[0017] Furthermore, the filter unit of the filter assembly is a conical filter cylinder. When impurities adhere to the filter cylinder during filtration, they can move to both sides along its inclined surface under the action of gas. This helps to prevent impurities from accumulating on the conical filter cylinder and affecting the exhaust effect, which helps to extend the service life of the conical filter cylinder after a single cleaning and reduces the cleaning frequency.

[0018] The exhaust valve seat described in this utility model is connected to the top of the fixed shell by a conical filter cylinder, which can be disassembled by rotating the rotating block. This facilitates the disassembly and cleaning of the conical filter cylinder without disassembling the exhaust valve, thus improving the convenience of cleaning. At the same time, the conical filter cylinder and the threaded block are connected by a plug-in method, which further facilitates the disassembly of the filter cylinder for individual cleaning and replacement, thereby further improving the ease of operation. Moreover, when damaged, only the conical filter cylinder needs to be replaced, which helps to reduce maintenance costs. Attached Figure Description

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] like Figure 1-6As shown in the figure, as an embodiment, an exhaust valve seat includes a fixed shell 1, a fixed pipe 11 is fixedly connected to the bottom of the fixed shell 1, a connecting plate 12 is fixedly fitted to the tail end of the fixed pipe 11, and a connecting pipe 13 is fixedly connected to the upper side of one side wall of the fixed shell 1.

[0033] Specifically, in actual use, the connecting plate 12 is connected to the pipe, and then the connecting pipe 13 is connected to the exhaust valve. During use, the gas in the pipe can enter the connecting pipe 13 through the fixed shell 1, and then enter the exhaust valve for exhaust.

[0034] It also includes a filter assembly. The top of the fixed shell 1 has a threaded hole 16. The filter assembly is inserted into the threaded hole 16. The filter assembly includes a conical filter cylinder 2. A cross plate 21 is fixedly connected to the top of the conical filter cylinder 2. A threaded block 23 is connected to the top of the cross plate 21 through a connector. The threaded block 23 engages with the threaded hole 16. An end plate 24 is fixedly connected to the top of the threaded block 23.

[0035] It should be understood that in actual use, the connecting plate 12 is first connected to the pipe, then the connecting pipe 13 is connected to the exhaust valve. When exhaust is required, the gas enters the inner cavity of the fixed shell 1 through the fixed pipe 11, thereby using the conical filter cylinder 2 to filter impurities. This helps to prevent impurities from entering the exhaust valve under the action of the gas and causing wear on the inner wall of the exhaust valve, thus extending the service life of the exhaust valve. Furthermore, when impurities adhere to the conical filter cylinder 2 during the filtration process, they can move to both sides along its inclined surface under the action of the gas. This helps to prevent impurities from accumulating on the conical filter cylinder 2 and affecting the exhaust effect, thus extending the service life of the conical filter cylinder 2 after a single cleaning and reducing the cleaning frequency.

[0036] Furthermore, the conical filter cylinder 2 is inserted into the top of the fixed shell 1, so that by rotating the rotating block 25, the threaded block 23 and the threaded hole 16 can be separated, making it easy to disassemble and clean the conical filter cylinder 2 without disassembling the exhaust valve, which improves the convenience of cleaning.

[0037] It is worth mentioning that a rotating block 25 is fixedly connected to the top of the end plate 24. The top of the rotating block 25 has an internal hexagonal groove. The rotating block 25 makes it easy to rotate the end plate 24, thereby indirectly driving the threaded block 23 to rotate, which facilitates disassembly. At the same time, the internal hexagonal groove makes it easy to operate with an internal hexagonal wrench, making the operation less strenuous.

[0038] It is worth noting that the inner wall of the outer end of the connecting pipe 13 is provided with an internal thread 14. The internal thread 14 makes it convenient to connect with the external threaded pipe at the tail end of the exhaust valve.

[0039] like Figure 1-3As shown in the figure, in one embodiment, the outer wall of the connecting plate 12 is provided with a number of connecting holes. The number of connecting holes is multiple and they are evenly distributed in a circle on the top of the connecting plate 12. The connection holes make it convenient to connect and fix the connecting plate 12 to the flange on the pipe using bolts, nuts and nuts.

[0040] like Figure 1-3 As shown in the figure, in one embodiment, the inner cavity of the fixed shell 1 is integrally formed with a circular step 15, and the outer diameter of the circular step 15 is the same as the outer diameter of the top of the conical filter cylinder 2. The circular step 15 is provided so that the conical filter cylinder 2 can overlap on the circular step 15 after being inserted into the inner cavity of the fixed shell 1, thereby achieving a close fit. This helps to improve the stability of the conical filter cylinder 2 during use, and at the same time helps to avoid gaps, allowing impurities to pass through the gaps.

[0041] like Figure 4-6 As shown in the figure, as an embodiment, the connector includes a sleeve 22, the tail end of the sleeve 22 is fixedly connected to the top middle of the cross plate 21, a matching insert rod 26 is inserted into the inner cavity of the sleeve 22, a first magnet block 27 is fixedly connected to the tail end of the insert rod 26, and a second magnet block 28 is fixedly installed at the bottom of the inner cavity of the sleeve 22.

[0042] It should be understood that by using the adsorption of the first magnet 27 and the second magnet 28, the sleeve 22 can be stably fitted onto the insertion rod 26. When disassembling the conical filter cylinder 2 for cleaning or replacement, the first magnet 27 and the second magnet 28 can be separated by pulling the conical filter cylinder 2, thereby directly removing the conical filter cylinder 2. This further improves the convenience of cleaning. Furthermore, when the conical filter cylinder 2 is damaged, it is not necessary to replace the entire filter assembly; only the conical filter cylinder 2 needs to be replaced, which helps reduce maintenance costs.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
