Embodiment Construction

[0008] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0009] With reference to the accompanying drawings, the present invention includes a stabilizer body 1, which is in the shape of a joint, with a primary thread and a secondary thread in the stabilizer body 1, and a thread between the primary thread and the secondary thread. The fluid buffer chamber 4 is provided with a primary helix 3 and a secondary helix 2 on the inner side of the primary thread and the secondary thread respectively. 2 There is a certain gap between the primary and secondary threads corresponding to it.

[0010] When in use, the invention is connected to the pipeline in front of the measuring element, and the measured medium enters the measuring element after flowing through the stabilizer. Since the present invention uses the pressure of the measured medium to be transmitted to the measuring element after passing through the gap between t...

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...
