Abstract:

As an advanced heat metering method, on-off valve regulation method has good temperature-control and energy-saving effects. But its hydraulic regime is different from other existing systems, the conditions are more complicated and researches are not enough. There is an opinion that differential pressure valve should be used in the buildings consumer heat inlet. For all the questions and uncertainties, this article conducted researches by field test and program simulation analysis. The field test was conducted in a housing estate in Beijing, one buildings flow regulations influence on other buildings hydraulic regime was tested. The simulation was done in HACNet hydraulic simulation software. A pipe net model was built to simulate different working conditions. Both results indicate that systems hydraulic regime is stable and differential pressure valve is not necessary.

Abstract:

The cut-off valve based on pilot valve controlling is a new kind of valve which opens and closes fast and has low driving energy consumption. Because of the complexity of the internal flow and uncertainty of the internal pressure, there is uncertainty in the design of the key structure. We simulate the whole opening process of the valve under different key structural dimensions with Fluent Dynamic Mesh and UDFs, and we do experiments to authenticate simulation results. The turn-on time we get from the simulation is the same as that from experiments under the valves actual operating conditions, in other words, the simulation results are correct, so we can identify the valve flow and get the internal pressure data which provides a reliable basis for the design of the key structural dimensions.

Abstract:

Objectives: To validate a self-expanding transcatheter valve for off-pump transatrial mitral valve-in-ring (VIR) implantation via a left thoracotomy. Methods: Mitral valve annuloplasty was performed via sternotomy during cardiopulmonary bypass on 9 pigs. After successful weaning from extracorporal circulation, the custom-made, self-expanding transcatheter VIR device was deployed under fluoroscopic guidance within the annuloplasty ring via a left thoracotomy. Hemodynamic data before and after the implantation were recorded. Mitral annulus diameter and valve area were measured by echocardiography. Transvalvular and left-ventricular outflow-tract pressure gradient were measured invasively. Results: Eight successful implantations were performed. Implantation failed in 1 pig because of difficulty with technical delivery of the sheath. Mean transatrial procedure time was 12.6 ± 1.7 min. Hemodynamic status during transatrial implantation was stable, and differences were not statistically significant. Mean mitral annulus diameter and mean mitral orifice area were 2.32 ± 0.2 and 3.84 ± 0.55 cm2, respectively. Mild regurgitation was detected in 7 animals and moderate regurgitation in 1. Mean gradients were 6.1 ± 5.0 mm Hg across the device. Postmortem examination confirmed adequate positioning of devices within the annuloplasty ring. Conclusions: This custom-made transcatheter device allows for safe and reproducible off-pump transatrial mitral VIR implantations. Transatrial access is a promising route to facilitate VIR implantations. Our custom-made stent-valve may be suitable for VIR procedures.

Abstract:

Transcatheter aortic valve replacement is a less invasive alternative for high-risk patients. However, valve embolization is a rare but dreaded complication. We report the successful off-pump retrieval of an embolized valve after transfemoral transcatheter aortic valve replacement through a left anterior thoracotomy. We maintained the embolized valve on the guidewire and snared it using a transapical approach. We then deployed a valve in an adequate position to ensure hemodynamic stability before transapical removal of the embolized valve. Transapical exteriorization of the femoral guidewire offers additional support, particularly in patients with a horizontal aortic annulus.

Abstract:

The system is under the control of electro-hydraulic servo loop, and makes it possible to automatically adjust the valve in real time. It uses the accumulator as a power source of emergency cut-off to achieve cut-off of the valve. Based on AMESim, we established a mathematical model of the Emergency Cut-off Valve that can make a simulation analysis about the data of displacement, velocity, acceleration when it shut down. This study provides a theoretical basis to the analysis and design of Emergency Cut-off Valve.
