Embodiment Construction

[0019] The following embodiments can make those skilled in the art understand the present invention more comprehensively, but do not limit the present invention to the scope of the described embodiments.

[0020] like figure 1 figure 2 A high temperature and high pressure fluid test kettle is shown, including a kettle body 1, an end plug 2, a left head 3, a right head 4, an ultrasonic probe 5, a fixed test rod 6, a movable test rod 7 and a piston rod 8.

[0021] The kettle body 1 has a cylindrical structure with openings at both ends; the end plug 2 includes a left end plug 21 and a right end plug 22 and are respectively arranged on the left and right ends of the kettle body to form a fluid test cavity 9 with the kettle body.

[0022] The left end plug 21 and the left head 3 are both coaxially provided with a first through hole along the axis direction for accommodating the fixed test rod 6 passing through, and the fixed test rod 6 extends through the left end plug 21 and th...

Abstract

The invention relates to a test kettle for high temperature and high pressure fluid. The test kettle is characterized in that the test kettle comprises a kettle body, an end plug, a left seal head, aright seal head, ultrasonic probes, a fixed test rod, a movable test rod, and a piston rod; the ultrasonic probes are directly arranged in a fluid test cavity and contacts with the high temperature and high pressure fluid directly, so as to avoid the interference from other mediums; the outer wall of the kettle body is heated by a spiral heating tube to provide a high temperature; the ultrasonic probe at one end is fixed, and the ultrasonic probe at the other end can test parameters of the fluid by utilizing the doppler effect of ultrasonic through the driving displacement of the piston rod. The parameters of the fluid can be tested for many times, so that the test data is more scientific, the test result error is less, and the precision is higher.

Description

technical field [0001] The invention relates to the field of fluid testing, in particular to a high temperature and high pressure fluid testing kettle. Background technique [0002] The use of ultrasonic Doppler effect to measure fluid is a main way to measure fluid, and it is insensitive to changes in temperature, pressure, viscosity and other factors, with high measurement accuracy and fast response to mixed fluids; testing of ordinary fluids It is used to measure liquids containing a certain reflective medium. It is generally installed outside the wall of the kettle to be measured, and does not need to be in contact with the fluid to be measured, and does not interfere with the flow of the fluid. There is no zero-point drift. In this way, the kettle containing high temperature and high pressure fluid will have an impact on the test. The measurement effect of this non-contact method will cause a large test error due to the existence of air medium. Therefore, it is necessar...
