AI Technical Summary
Due to the fixed length of the diaphragm box, the existing plug-in diaphragm box instrument cannot be adjusted according to the pressure port insertion data of different equipment, resulting in no interoperability of spare parts, which increases procurement costs.
A segmented insertable membrane box is designed, including a fixed section and an extended section, which enables the adjustment of the length of the membrane box through threaded connections, allowing the adjustment of the membrane box length as needed.
It realizes flexible adjustment of the length of the membrane box, reduces the cost of single procurement, reduces the cost of spare parts procurement, and improves the applicability of the equipment.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of instrument equipment, and in particular relates to an adjustable plug-in membrane box instrument. Background Art
[0002] Insert flange capillary pressure transmitter and liquid level gauge are widely used instruments in petrochemical industry. Because this type of instrument replaces the pressure lead pipe with a capillary filled with silicone oil, the measuring diaphragm is in direct contact with the medium, and the process medium does not need to enter the pressure lead pipe, thus avoiding many measurement errors and circuit failures caused by changes in process medium characteristics. It has many advantages that ordinary pressure transmitters do not have. The use of this type of instrument can greatly enhance the stability of measurement and reduce the workload of instrument maintenance personnel. The above instruments are widely used in chemical production.
[0003] The applicant discovered a serious problem when using the above-mentioned instrument. Since the diaphragm box, capillary tube and meter body of this type of instrument need to be designed as an integrated package, customization can only be carried out after confirming the insertion depth data of the pressure port of the equipment during actual application. Since the applicant uses a wide variety of equipment in the actual production process, the pressure port insertion depth data is required to be different, resulting in different measuring diaphragm box lengths. Since diaphragm boxes with different insertion depths cannot be replaced, different instrument spare parts cannot be used interchangeably. Each instrument can only be purchased separately as a special instrument, and the spare parts procurement cost has increased significantly. In order to solve the above-mentioned technical problems, the applicant specially established a technical discussion group. After a month of discussion and research, it finally developed a product that can solve the above-mentioned technical problems. After many tests, it obtained very good feedback. Utility Model Content
[0004] In order to solve the technical problems raised in the background technology, the utility model perfectly solves the technical problems raised in the background technology through a segmented design, and the technical solutions adopted are as follows:
[0005] An adjustable plug-in membrane box instrument includes a transmitter and a capillary tube, and the transmitter is connected to a flange. Since the above-mentioned device belongs to the prior art, the applicant will not repeat it here. The core improvements of the utility model are as follows:
[0006] The lower part of the flange is connected to the inserted membrane box, and the inserted membrane box is divided into a fixed section and an extension section. The fixed section and the extension section are threadedly sealed to form a whole. The outer surface of the fixed section is a threaded structure, and the inner surface of the extension section is a threaded structure. The length of the inserted membrane box is determined by the length of the threaded connection between the outside of the fixed section and the inside of the extension section. The working principle of the utility model is as follows: when inserted membrane boxes of different lengths are required, the length of the threaded connection between the extension section and the fixed section can be changed to obtain inserted membrane boxes of different lengths by rotating the length of the threaded connection. At this time, the technical problem that the length of the membrane box cannot be changed is completely solved. In actual operation, the utility model is easy to operate and suitable for production applications.
[0007] Preferably: the extension section of the utility model is made of metal material, and different corrosion-resistant materials are selected according to different liquids.
[0008] Compared with the prior art, the utility model has the following beneficial effects: through the structural transformation of the utility model, the existing fixed-length membrane box can be adjusted and designed according to actual needs, so as to meet the requirements of plug-in membrane boxes of different lengths, reduce the procurement cost of single procurement, save a lot of expenses for the enterprise every year, and have a good effect in actual application.

[0013] Comparative Example 1
[0014] like Figure 1 As shown:
[0015] An adjustable insertable diaphragm box instrument includes a transmitter 1 and a capillary 7. The transmitter 1 is connected to a flange 2, and the lower part of the flange 2 is connected to the insertable diaphragm box. Such a design will cause the technical problems raised in the background technology. When insertable diaphragm boxes of different concentrations are needed, they need to be purchased separately, which increases the procurement cost.
[0016] Example 1
[0017] like Figure 2 , Figure 3As shown:
[0018] An adjustable insertable diaphragm box instrument includes a transmitter 1 and a capillary tube 7, wherein the transmitter 1 is connected to a flange 2, and the lower part of the flange 2 is connected to the insertable diaphragm box, and is characterized in that:
[0019] The insertable membrane box is divided into a fixed section 4 and an extended section 5. The fixed section 4 and the extended section 5 are threadedly sealed to form a whole.
[0020] The outer surface of the fixed section 4 is a threaded structure, and the inner surface of the extended section 5 is a threaded structure. The length of the inserted membrane box is determined by the length of the threaded connection between the outer portion of the fixed section 4 and the inner portion of the extended section 5.
[0021] The working principle of the utility model is as follows: when different lengths of insertable membrane boxes are required, the length of the threaded connection between the rotating extension section 5 and the fixed section 4 can be changed to obtain insertable membrane boxes of different lengths. In actual operation, the utility model is easy to operate and suitable for production applications.
