Thread stabilizer

Abstract

The invention discloses a thread stabilizer, comprising a joint shape stabilizer body. A first thread and a second thread are arranged in the stabilizer body. A fluid buffer chamber is arranged between the first thread and the second thread. A first-order spiral body and a second-order spiral body are arranged on the inner sides of the first thread and the second thread. The spiral body cooperateswith the corresponding thread. A gap is arranged between the first spiral body and the corresponding thread, and a gap is arranged between the second spiral body and the corresponding thread. The thread stabilizer has the advantage of reducing the pressure pulsation amplitude of the medium from the source point. Therefore, the medium pressure measured by a detecting element is stable, which improves the measurement accuracy and protects measuring components. The invention is widely used in measurement situations such as pressure or flow rate of fluids related to fluid pressure pulsation amplitude.

Description

technical field [0001] The invention relates to a measurement control device belonging to fluid pressure, and relates to a fluid pressure pulsation stabilizer. Background technique [0002] The measuring element used in the pressure detection process is mainly a spring tube, which is very sensitive to the pulsation change of the pressure source. When the pulsation amplitude exceeds its insensitive area, the pointer of the indicating instrument starts to oscillate. The greater the pulsation amplitude, the greater the oscillation The larger it is, this is especially prominent in outlet pressure instruments such as pumps. The current situation is that the general pressure indicating instrument can only swing for a period of time, and the primary measuring element of the remote instrument and the automatic control device can also only swing freely, but in order to realize the recording and automatic control, it is added in the electrical part Damper, that is to say, there is no...

Problems solved by technology

The current situation is that the general pressure indicating instrument can only swing for a period of time, and the primary measuring element of the remote instrument and the automatic control device can also only swing freely, but in order to realize the recording and automatic control, it is added in the electrical part Damper, that is to say, there is no device that can make the primary pressure measuring element measure stably

[0003] With the development of modern industrialization, the requirements for the accuracy of automatic pressure control are getting higher and higher. For the measuring element with large fluid pressure pulsation, the mechanical wear of the transmission part and the fatigue of metal materials caused by the pulsation reduce the The measurement accuracy cannot meet the needs of automatic control

Therefore, simply relying on adding a damper from the electrical part instead of stabilizing the pulsation of the measured medium from the primary measurement part, finding a way from the source cannot meet the needs
