Detailed Description
The following description will further describe embodiments of the present invention with reference to the accompanying drawings and examples. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
As shown in fig. 1, the present invention relates to a firm plastic diaphragm body, comprising:
Specifically, the upper connector 2 is provided with an internal thread 9, and the lower connector 3 is provided with an external thread 10, so that the upper connector can be connected with the anticorrosion process of the pressure instrument, petrochemical industry, pipeline connection and other industries.
Wherein, the material of going up connector 2, lower connector 3 and diaphragm 6 is plastics, and the material of assembly bolt 7, metal clamping piece and becket 8 is the metal material such as stainless steel, adopts metal and plastics combination assembly, greatly increased the firmness.
The working principle is as follows:
the metal clamping piece is sleeved on the diaphragm body 1 and fixedly connected through the assembling bolt 7, and the clamping force on the diaphragm 6 is increased by locking the assembling bolt 7 during use. Because the compression strength of the diaphragm 6 and the compressed force of the diaphragm 6 are in a certain coefficient direct proportion relationship, the pressure-bearing range of the diaphragm is larger, and the maximum pressure-bearing range is improved from the prior maximum pressure-bearing range only of 0.6MPa to the present maximum pressure-bearing range of 4.0 MPa.
The utility model has the advantages and beneficial effect:
1. the assembly of the outer sleeve type clamping piece is adopted, so that the bolt is more stressed when being locked, the assembly firmness and later-period anti-seismic effects are greatly improved, the bolt can be used in an environment with higher anti-seismic grade, and the running ranges of a pressure measuring instrument and a pipeline are improved;
2. the outer ring of the neck part of the internal thread is embedded with the metal ring, so that the instrument can be assembled more firmly during assembly;
3. the pressure-bearing device can be applied to the operation environment with the maximum pressure-bearing medium pressure value of 4.0MPa, and has the advantages of simple structure, easy processing, low price, pure mechanical structure, safety and reliability.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
