型号1710平衡截止阀是直线型结构，其阀杆与阀瓣垂直于水流方向，而不是常规的倾斜式Y形截止阀结构。与倾斜式结构相比，直线式结构截止阀在全开位置具有更高的压差(压力损失)。全开位置上的直线式结构阀门通常比倾斜式结构的流通能力小20%.
The Fig. 1710 Balancing globe valve is a straight
pattern design having the stem/disc arrangement vertical to the direction
of flow compared to conventional oblique "Y" pattern globe valves.
The full open position in straight pattern globe valves has higher differential
pressure (pressure losses) than an oblique pattern valve. The flow capacity
of the straight pattern valve in the full open position is typically 20%
lower than the oblique type.
在较低流量下，型号1710平衡阀的较高压力信号将由流量测量辅助产生，相当于全开位置流量范围的20%. 全开位置25%的流量特性取决于阀瓣外形，与阀体结构无关。
The higher pressure signals on the Fig 1710 balancing
valve will assist with flow measurement at lower flow rates, extending
the full open flow range by 20%. The characteristic at the 25% open position
is due to the disc profile and is not affected by the body pattern.
型号1710平衡阀为暗杆结构，配置抛物线(塞)形阀瓣。每个阀门配置2个压力测试点，红带表示上游(高压)，蓝带表示下游(低压)，用于压差测量。手轮总装配置指示器窗口，黑色数字表示全开位置，红色数字表示旋转幅度的十分之一。主阀轴配置一个内轴，适用于双重调节止动记忆和阀门位置设置。
The Fig. 1710 Balancing valve is a non-rising
stem design incorporating a parabolic (plug) shaped disc. Each valve is
fitted with 2 pressure test points, red strap indicating upstream (high
pressure) and blue strap indicating downstream (low pressure) for differential
pressure measurement. The handwheel assembly incorporates an indicator
window, with a Black numeral for full turns and a Red numeral for tenths
of turns. The main valve spindle incorporates an inner spindle for double
regulation memory stop and valve position setting. |
