Detailed Description
The utility model provides a buffer for reducing the influence of pressure pulsation on a sensor sensitive element, in particular to a pressure sensing buffer device of an aircraft lubricating oil circuit pressure measurement signal device.
Wherein the buffer device is installed at the pressure interface of the annunciator. The buffer device mainly converts fluid kinetic energy into internal energy through a group of buffer sheets 4 which are staggered with each other so as to achieve the purpose of reducing pressure. Compared with a pressure signal device without a buffer, the pressure signal device has the advantages that the stress level of the product under each pressure condition is greatly reduced, and the alternating life is greatly prolonged.
The utility model belongs to the field of depressurization of aviation annunciators, and relates to a buffer for depressurization of a pressure annunciator, as shown in fig. 1. The utility model provides a buffer device which mainly comprises a buffer sheet 4, a gasket 3, a filter screen 2 and a shell 1.
In one possible implementation, during operation, fluid passes through the buffer plate to generate vortex, fluid kinetic energy is consumed to be converted into internal energy, pressure peaks of the rapidly-changing pressure signals are reduced, the influence of pressure pulsation on the sensitive elements of the annunciators is reduced, and the service lives of the annunciators are prolonged. The utility model solves the problems of high pressure peak value and short service life of the traditional pressure annunciator, and improves the reliability of the annunciator.
The utility model overcomes the defects in the prior art, can be added without changing the appearance of the existing product, reduces the influence of pressure pulsation on the sensor sensitive element, reduces the stress level of the product and prolongs the service life of the product.
