Description

Technical Field

[0001] This utility model relates to the technical field of miniature flush membrane split-type pressure transmitters, and in particular to a miniature flush membrane split-type pressure transmitter with a water filtration mechanism. Background Technology

[0002] The miniature flush diaphragm split-type pressure transmitter is a pressure measuring instrument with a special structural design. Its core feature is that the contact surface between the measuring diaphragm and the measured medium is on the same plane, without any protruding or recessed parts. This design allows the diaphragm to directly contact the measured medium, thereby transmitting pressure signals more accurately.

[0003] Existing miniature flush-film split-type pressure transmitters are typically threaded into water pipes and use their sensing end to contact the water in the pipe. This allows them to detect and reflect the water pressure in the pipe. However, the sensing end of these transmitters lacks a water filtration component, allowing impurities and algae in the water to adhere to it, potentially affecting the pressure monitoring. Therefore, existing miniature flush-film split-type pressure transmitters without a filter at the sensing end are inconvenient to use. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing miniature flush membrane split-type pressure transmitters, where the sensing end lacks a filter component, and to provide a miniature flush membrane split-type pressure transmitter with a water filtration mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a miniature flush membrane split-type pressure transmitter with a water filtration mechanism, comprising: a connecting mechanism, the connecting mechanism including a pressure transmitter body, one end of the pressure transmitter body being provided with a filtration mechanism, the filtration mechanism including an internally threaded tube, a barrier ring sleeved inside the internally threaded tube, a molding ring sleeved inside the internally threaded tube, the number of molding rings being three, a spacer ring sleeved inside the internally threaded tube, the spacer ring being slidably connected to the inner wall of the internally threaded tube, a stainless steel mesh layer being fixedly connected inside one of the molding rings, a PP filter cotton layer being fixedly connected inside one of the molding rings, and a reverse osmosis membrane layer being fixedly connected inside the other molding ring.

[0006] In a preferred embodiment, the internally threaded tube is fixedly connected to the pressure transmitter body, and the barrier ring is fixedly connected to the internally threaded tube.

[0007] In a preferred embodiment, the forming ring is slidably connected to the inner wall of the internally threaded tube, and the internally threaded tube is fitted with a threaded ring.

[0008] In a preferred embodiment, the threaded ring is threaded to the inner wall of the internally threaded pipe, and the threaded ring has an embedding groove.

[0009] In a preferred embodiment, a water supply pipe is provided on one side of the pressure transmitter body, and an external threaded pipe is sleeved inside the water supply pipe, and the external threaded pipe is fixedly connected to the water supply pipe.

[0010] In a preferred embodiment, the pressure transmitter body and the internal threaded tube are sleeved inside the external threaded tube, and the pressure transmitter body and the internal threaded tube are slidably connected to the inner wall of the external threaded tube.

[0011] In a preferred embodiment, threaded connecting blocks are fitted onto the outer surfaces of both the external threaded pipe and the pressure transmitter body, and the threaded connecting blocks are threadedly connected to both the pressure transmitter body and the external threaded pipe.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] This invention incorporates a filtration mechanism positioned at the sensing end of the pressure transmitter body. This filtration mechanism filters the water in contact with the pressure transmitter, preventing algae and impurities from adhering to the sensing end and ensuring constant direct contact with pressurized water. This allows for more accurate water pressure monitoring by the pressure transmitter. Furthermore, three shaping rings are incorporated to accommodate the stainless steel mesh layer, PP filter cotton layer, and reverse osmosis membrane layer, ensuring they maintain their normal operating shape under water pressure. Finally, threaded rings are incorporated and threaded into the internal threaded pipe, preventing the shaping rings and spacer rings from adhering to the internal threaded pipe and facilitating easy replacement.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] like Figures 1-5 As shown, this utility model provides a technical solution: a miniature flush membrane split-type pressure transmitter with a water filtration mechanism, comprising: a connecting mechanism 1, the connecting mechanism 1 including a pressure transmitter body 11, a filtration mechanism 2 provided at one end of the pressure transmitter body 11, the filtration mechanism 2 including an internally threaded tube 21, a blocking ring 22 sleeved inside the internally threaded tube 21, three shaping rings 23 sleeved inside the internally threaded tube 21, and a spacer ring 24 sleeved inside the internally threaded tube 21, the spacer ring 24 being slidably connected to the inner wall of the internally threaded tube 21. One of the shaping rings 23 has a stainless steel mesh layer 25 fixedly connected inside, another of the shaping rings 23 has a PP filter cotton layer 26 fixedly connected inside, and the third of the shaping rings 23 has a reverse osmosis membrane layer 27 fixedly connected inside. The internally threaded tube 21 is fixedly connected to the pressure transmitter body 11. The barrier ring 22 is fixedly connected to the internally threaded tube 21. The shaping ring 23 is slidably connected to the inner wall of the internally threaded tube 21. A threaded ring 28 is sleeved inside the internally threaded tube 21. The threaded ring 28 is threadedly connected to the inner wall of the internally threaded tube 21. An embedded groove 29 is provided on the threaded ring 28.

[0024] In this embodiment, by setting a barrier ring 22 and placing it near the sensing end of the internally threaded tube 21 close to the pressure transmitter body 11, a certain space is maintained between the internally threaded tube 21 and the sensing end of the pressure transmitter body 11 under the barrier of the barrier ring 22, allowing water to directly contact the sensing end. Furthermore, three shaping rings 23 are provided, allowing the stainless steel mesh layer 25, PP filter cotton layer 26, and reverse osmosis membrane layer 27 to be installed, thus enabling the stainless steel mesh layer 25, PP filter cotton layer 26, and reverse osmosis membrane layer 27 to be installed within the membrane. Under water pressure, it can always maintain normal operating conditions and filter water. In addition, a stainless steel mesh layer 25 is provided, which can block larger stones and rust pieces, so that they will not affect the PP filter cotton layer 26 and the reverse osmosis membrane layer 27. The PP filter cotton layer 26 can filter silt and algae suspended solids. In addition, the reverse osmosis membrane layer 27 can effectively filter mineral impurities in the water, making the water cleaner. Thus, the sensing end of the pressure transmitter body 11 can be kept clean.

[0025] Example 2

[0026] like Figures 1-5 As shown, a water supply pipe 12 is provided on one side of the pressure transmitter body 11. An external threaded pipe 13 is sleeved inside the water supply pipe 12. The external threaded pipe 13 is fixedly connected to the water supply pipe 12. The pressure transmitter body 11 and the internal threaded pipe 21 are sleeved inside the external threaded pipe 13. The pressure transmitter body 11, the internal threaded pipe 21 and the inner wall of the external threaded pipe 13 are all slidably connected. Threaded connecting blocks 14 are sleeved on the outer surfaces of the external threaded pipe 13 and the pressure transmitter body 11. The threaded connecting blocks 14 are threadedly connected to the pressure transmitter body 11 and the external threaded pipe 13.

[0027] In this embodiment, by setting a threaded ring 28, which is threadedly connected to the internal threaded tube 21, the threaded ring 28 can block components such as the plastic ring 23 and the spacer ring 24, allowing them to be stably placed inside the internal threaded tube 21 and easily replaced. An embedding groove 29 is provided on the threaded ring 28, allowing monitoring personnel to rotate the threaded ring 28 using a tool suitable for the embedding groove 29. Thus, the threaded ring 28 can be connected to or disconnected from the internal threaded tube 21. A threaded connecting block 14 is set, which is threadedly connected to both the pressure transmitter body 11 and the external threaded tube 13. Thus, the threaded connecting block 14 can connect the pressure transmitter body 11 and the external threaded tube 13, allowing the pressure transmitter body 11 to drive the filter mechanism 2 to be stably installed inside the external threaded tube 13.

[0028] Working principle:

[0029] like Figures 1-5As shown, in use, the filter mechanism 2 can be assembled first. First, the reverse osmosis membrane layer 27, along with a molded ring 23 fixedly connected to it, is slidably installed into the interior of the internally threaded tube 21, where the molded ring 23 will fit against the barrier ring 22. Then, a spacer ring 24 is installed into the internally threaded tube 21. Next, the PP filter cotton layer 26, along with the molded ring 23 fixedly connected to it, is installed into the interior of the internally threaded tube 21, and another spacer ring 24 is installed. Finally, the stainless steel mesh layer 25, along with the molded ring 23 fixedly connected to it, is installed into the interior of the internally threaded tube 21. Then, a sheet-like auxiliary tool is used to fit into the embedding groove 29, causing the threaded ring 28 to form a tight threaded connection with the internally threaded tube 21. Thus, the threaded ring 28 can squeeze and limit the molded ring 23 and other components. Finally, the pressure transmitter body 11 is installed, and the pressure transmitter body 11 can drive the filter... The filter mechanism 2 enters the interior of the external threaded tube 13, and O-rings are installed on the existing pressure transmitter body 11. Thus, the connection between the pressure transmitter body 11 and the external threaded tube 13 can be in a sealed state until one end of the external threaded tube 13 is placed at the end of the threaded connecting block 14. Then, the threaded connecting block 14 is rotated, and the threaded connecting block 14 is threadedly connected to both the pressure transmitter body 11 and the external threaded tube 13 until the end of the external threaded tube 13 contacts the inner wall of the threaded connecting block 14. Thus, the threaded connecting block 14 can firmly connect the pressure transmitter body 11 and the external threaded tube 13. After that, some of the water in the pressure transmitter body 11 will enter the interior of the external threaded tube 13, and the water will be filtered in sequence by the stainless steel mesh layer 25, the PP filter cotton layer 26, and the reverse osmosis membrane layer 27. Thus, the water in contact with the sensing end of the pressure transmitter body 11 is clean, and the pressure transmitter body 11 can effectively monitor the water pressure.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
