详细介绍: 进口蒸汽减压阀
蒸汽减压阀介绍:
蒸汽减压阀是采用控制阀体内的启闭件的开度来调节介质的流量,将介质的压力降低,同时借助阀后压力的作用调节启闭件的开度,使阀后压力保持在一定范围内,在进口压力不断变化的情况下,保持出口压力在设定的范围内,保护其后的生活生产器具。蒸汽减压阀一般采用水平安装,由阀后压力进行控制。当压力感应器检测到阀门压力指示升高时,减压阀阀门开度减小;当检测到减压阀后压力减小,减压阀阀门开度增大,以满足控制要求。蒸汽减压阀—该阀门的减压比必须在一定程度上高于系统值; 即使在最大或者最小流量时它也应该能够对正作用或者反作用控制信号做出响应。这些阀门应该针对有用控制范围选择,即最大流量的20%到80%。正常为等比型或者具有等比特性。这些类型的阀门本身具有比例控制所要求的最佳流量特性及流量范围。
进口蒸汽减压阀有以下特征:
1、蒸汽减压阀选用优质上等材料,做工精细,能准确控制阀后压力,并保持阀后压力稳定;
2、蒸汽减压阀采用硬质不锈钢阀芯/ 阀座,耐磨性佳;
3、蒸汽减压阀阀口经研磨处理,泄露率可达ANSI6级;
4、蒸汽减压阀能有效控制出口压力,提供用气点自动精确、可靠、低成本的减低蒸汽;
进口蒸汽减压工作原理:
减压阀是通过启闭件的节流,将进口压力减至某一需要的出口压力,并使出口压力保持稳定。减压阀出厂时,调节弹簧处于未压缩状态,此时主阀瓣和付阀瓣处于关闭状态,使用时按顺时针转动调节螺钉,压缩调节弹簧,使膜瓣移顶开付阀瓣,介质由a孔通过付阀座到b孔进入活塞上方,活塞在介质压力的作用下,向下移动推动主阀瓣离开主阀座,使介质流向阀后。同时由c孔进入膜片下方,当阀后压力超过调定压力时,推动膜片上移压缩调节弹簧,付阀瓣随之向关闭方向移动,使流入活塞上方的介质减小,压力也随之下降,此时的主阀瓣在主阀瓣弹簧力的推动上下移,使主阀瓣与主阀座的间隙减小,介质流量也随之减小,使阀后压力也随之下降到新的平衡,反之当阀后压力低于调定压力时,主阀瓣与主阀座的间隙增大,介质流量也随之增加,使阀后压力也随之增高达到新的平衡。

Inlet steam valve
Steam valve descrtption:
Steam valve is the use of a control valve opening and closing parts of the body to regulate the flow of the medium, will reduce the pressure on the media, while the role of the pressure regulating valve after the aid of the opening and closing parts, so that the valve is maintained at a certain pressure within range, in the case of changing the inlet pressure, outlet pressure maintained within the set range, the protection of life and production equipment later. Steam valve is generally horizontal installation, is controlled by the valve pressure. When the pressure sensor detects pressure indicator rises to the valve, pressure reducing valve opening is reduced; when the detected pressure decreases valve, relief valve opening increases, in order to meet the control requirements. Steam valve - the valve must be higher than the system pressure than the value to some extent; even at the maximum or minimum flow when it should be able to respond to the positive effect or reaction control signal. These valves should be useful for the control of selection, 20% to 80% is the maximum flow. Normally has a geometric pattern or geometric properties. These types of proportional control valve itself having a desired optimum flow characteristics and flow range.
Inlet steam valve has the following characteristics:
A steam valve finest selection of quality materials and fine workmanship, can accurately control the valve pressure and keep the pressure stabilized valve;
2, the steam valve with hard stainless steel valve / seat, good wear resistance;
3, the steam pressure reducing valve port by grinding treatment, leak rate of ANSI6 level;
4, can effectively control the steam valve outlet pressure, provide accurate automatic gas point, reliable and cost-effective to reduce vapors;
Inlet steam pressure works:
Valve by opening and closing parts of the throttle, the inlet pressure is reduced to the outlet pressure of a need, and outlet pressure remains stable. Valve factory, adjust the spring in an uncompressed state, when the main valve and the valve is in the closed state to pay, according to the use of the screw clockwise to adjust, adjust compression spring, the film moves to open the top flap valve pay, media b by a hole to hole into the top of the piston seat by paying a piston in the role of media pressure, pushing down the main valve to move away from the main valve seat, with the media after the flow valve. C hole into the bottom while the diaphragm when the valve after the pressure exceeds the set pressure, the diaphragm adjustment push shift compression spring, pay clapper moves in the closing direction, reducing the flowing medium over the piston, with the pressure The decline, at this time the main valve push down on the main valve spring force, the main valve and the main seat of the gap is reduced, medium flow also decreases, so that the valve pressure to fall New Balance, and vice versa when the valve pressure is below the set pressure, the gap with the main seat main valve increases, medium flow also increases, so also will be increased after the valve pressure to reach a new equilibrium.
