“…Although a reducing valve beside the meter has no substantial influence on measurement, there is a slight tendency to both negative and positive errors (Figure 2e). Flow distortions caused by this type of valve are usually small on the upstream side of the pipe, as has been shown in a numerical simulation (Wei et al, 2015).…”

“…The reducing valve causes very small measurement errors, close to those obtained in an installation of straight pipe lengths (Figure 5e), due to the valve being downstream of the meter and, thus, not considerably distorting the meter's inlet flow. In a numerical simulation, this type of valve has been shown not to cause important upstream distortions (Wei et al, 2015).…”

As the correct measurement is an essential part of water management, this study describes the metrological behaviour of a range of bulk water meters under different installation configurations. The meters analysed included the horizontal and vertical Woltman, singlejet, tangential and proportional. Configurations included straight pipe lengths; gate and butterfly valves at different degrees of closure, rotations and distances from the meter; meter with volumetric and reducing valves; reverse installation; and meter rotated 90º from the horizontal setting. The metrological behaviour under different flow conditions was analysed by comparison with electromagnetic and volumetric meters (ISO-4064). The horizontal Woltman showed no permissible errors with reverse installation; gate valve closed 75% and placed alongside the meter; and with butterfly valve closed 30º, non-rotated, and rotated right or left. The vertical Woltman gave no permissible errors with reverse installation. The single-jet meter did not show any errors above the permitted limit. The tangential meter had no permissible errors with reverse installation and in almost all configurations with gate and butterfly valves. The proportional meter showed no permissible errors with a gate valve at any degree of closure.

“…4 Many measures and causes concerning the suppression and elimination of flow-induced noise have been carried out. Wei et al 5 studied the aerodynamic noise in the control valve with a perforated plate. Results are shown that the perforated plate affects the distribution of noise source, and the noise is changed profoundly under the different pressure difference.…”

Two-stage sleeve control valve has been widely implemented in high-pressure difference hydraulic system, whose function is to reduce hydrodynamic noise. The sleeve with orifices plays a significant role in reducing the hydrodynamic noise. The ratio of orifices diameter between outer sleeve and inner sleeve, Ri is investigated in this paper. The coupling effect of Ri on the flow field and hydrodynamic noise is analyzed deeply by URANS and FW-H model. Furthermore, the pressure, velocity, turbulent kinetic energy and sound pressure level of the flow field are monitored. The results indicate that higher Ri will restrict the flow velocity in the orifices, and the distributed pressure drop of two sleeves will be even. The velocity of flow in the outer sleeve reduces from 130 m/s to 90m/s with the increase of Ri. In addition, larger Ri can reduce the hydrodynamic noise and obtain higher flow capacity. When the Ri is 1.2, the sound power level distributes evenly in the gap, and the radiation intensity of the sound source is the smallest. The study can provide a reference for the design of sleeves in high-pressure control valves.

When check valve works in long distance or high lift liquid pipeline system, it is often subjected to water hammer. In this study, the UDF program was used to simulate the closing process of an axial flow check valve at the moment of pump shutdown, and the porous media model was applied to simulate the complete closing of the valve disc. It was found that there was local vacuum at the end of the valve disc at the moment when the valve was completely closed. The water hammer and characteristics of the force acting on the valve disc in the whole closing process were also obtained. In order to reduce the pressure surges on the valve disc and seat, a built-in critical damping was designed and added to the to the valve disc drive system. Since the spring force is directly proportional to the movement displacement of the valve disc, the elastic force and the speed of the valve disc reach the peak value when the valve is fully closed, while the damping force is directly proportional to the speed of the valve disc, therefore, the damping force increases gradually with the speed of the valve disc, which only produces the maximum damping force at the moment of fully closing, so as to reduce the slam shut, but has little effect on the closing time, thus adding damping is more effective than reducing the elastic force of spring. The current study provides a possible approach to protect the valve disc and seat of check valves in liquid supply and drainage systems.
