Problems solved by technology
The diaphragm in the traditional water pump pressure controller is a flat rubber sheet, which is fixed on the controller housing through the flange cover and is in contact with the pressure plate that transmits the pressure. Since the diaphragm is a flat surface and the material is easy to deform Rubber, after working for a short time, a groove will be formed at the position where it contacts the pressure plate, and the sensitivity of the deformed rubber sheet will be affected. The deformed position on the edge of the groove is easy to break after long-term work, and the diaphragm will be directly affected by damage. To the service life of the controller, the service life of the traditional diaphragm is only 300,000 times

Embodiment Construction
[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0019] refer to figure 1 , figure 2 , a pressure controller diaphragm, including a diaphragm body 1, the diaphragm body 1 includes a pressure sensing part 2 arranged in the middle and an installation part 3 arranged on the extension of the pressure sensing part 2, the pressure sensing part 2 is It is circular and protrudingly arranged in the middle of the installation part 3 , the connection between the pressure sensing part 2 and the installation part 2 is an arc connection, and the installation part 3 is provided with a plurality of installation holes 4 evenly.
[0020] Based on the above structure, the diaphragm body 1 directly reserves a space for the pressure plate, and its contact position with the pressure plate is not easy to deform or wear during the working process. The diaphragm body 1 can maintain a good working state and ensure its sensitivity....

Abstract
The invention belongs to the technical field of pressure controller spare and accessory parts, and particularly relates to a pressure controller diaphragm. The pressure controller diaphragm comprisesa diaphragm body, wherein the diaphragm body comprises a pressure induction part arranged in the middle and a mounting part arranged on the extension part of the pressure induction part; the pressureinduction part is round and is arranged in the middle of the mounting part in a protruding mode, and the pressure induction part and the mounting part are in arc connection; and a plurality of mounting holes are uniformly formed in the mounting part, and the diaphragm body is made of thermoplastic plastic TPV. Compared with a traditional diaphragm, space is reserved for a pressure plate directly,meanwhile, selected TPV material has excellent comprehensive performance, the contact position of the diaphragm body and the pressure plate is not prone to deformation during the working process, andthe diaphragm body is not prone to abrasion, so that the diaphragm can keep a good working state, induction sensitivity of the diaphragm is ensured, and meanwhile, the service life is relatively long.
Description
technical field [0001] The invention belongs to the technical field of pressure controller spare parts, and in particular relates to a diaphragm of a pressure controller. Background technique [0002] At present, in the water pump controller industry, most of the pressure signals are used to control all the start and stop actions of the water pump. There are two types of widely used ones: one is the mechanical spring type water pump pressure controller, which uses the compression deformation of the mechanical spring To control the pressure point, the other is the pressure sensor type water pump pressure controller, which controls the water pump by outputting the pressure control point signal through the pressure sensor, and finally meets the customer's use requirements. The industry offers a lot of convenience. [0003] Among them, the diaphragm in the pressure sensor type water pump pressure controller plays the role of sensing pressure, and its sensing sensitivity and ser...
