HVAC heating: static balance valve
Static balance valve, that is, the digital lock balance valve, is a static balance valve with hydraulic conditions, it has equal percentage of the flow characteristics of the curve, for centralized control, quality control and phased change of flow volume adjustment system, when When system flow changes, each branch with static balancing valve installed will increase or decrease in proportion to each user's flow, and maintain the flow distribution plan during initial adjustment. Static balance valve also has a degree of opening and opening degree of locking function, heating and air conditioning water system in the valve, can achieve the effect of saving heat and electricity.
Static balance valve performance and features:
1, excellent regulation performance.
2, excellent cut-off function.
3, accurate to 1/10 laps open the number of turns show.
4, the theoretical flow characteristic curve is equal percentage (approximate) characteristics, when the valve authority of 30-50%, the actual flow characteristics of linear.
5, with the opening lock function, non-property management staff can not change the setting status.
6, can be easily and effectively to adjust the pressure and flow, supporting intelligent instrument can easily display the working pressure and flow, guide and record balance adjustment program.
7, PTFE sealed, reliable sealing performance, long service life.
8, according to the percentage of its opening and the pressure before and after the valve can be calculated through the valve flow.
9, internal components made of stainless steel, copper alloy, anti-corrosion performance.
10, without lifting the stem within the reserved operating space.
During this initial phase, Design Engineers, Tooling Engineers, Materials Engineers, Manufacturing Engineers, Quality Engineers, and Lab Technicians work together to determine product specifications, tooling component capabilities, tooling materials, operating limitations, and any required product enhancements and improvements. The team specifically looked for any potential issues with part geometry or tolerances that could result in poor steel condition or require special tool features such as lifters, slides and threading/unthreading. The physical and chemical properties of the selected resins are also evaluated in order to select suitable mold steels and review mold cooling. In addition to determining the proper vent location, a mold flow evaluation is performed to determine the optimal gate type and gate location.
The manufacturability review includes the validation of standard plastic design practices and the incorporation of tooling details to create the most robust design possible. Tool specifications and tool provenance are finalized and purchased component sources are qualified. A comprehensive Process Failure Mode Effects Analysis (PFMEA) was also completed.
