Abstract: A thermostatic mixing valve including: a first fluid inlet; a second fluid inlet; an outlet; a thermostatic element connected to a return spring and a piston such that movement of the thermostatic element assists with moving the piston, movement of the piston controlling fluid flow from the first fluid inlet and the second fluid inlet to the outlet; a housing containing an overtravel spring, the overtravel spring configured to resist a force applied by the thermostatic element during movement thereof; and a plunger extending into the housing, the plunger configured to engage the overtravel spring, wherein rotating the plunger adjusts the resistance applied onto the thermostatic element from the overtravel spring.

Abstract: A water temperature regulating valve (10) including a valve body (12) having a cavity (13) in which mixing of fluids can occur, and provided with a hot fluid (or heated water) inlet (18) adapted for communication with a source of hot (or heated) water, a cooled fluid inlet (16) adapted for communication with an apparatus that has used the mixed fluid for heating, a mixed fluid outlet (14) adapted for communication with an apparatus that uses the mixed fluid for heating, and a return fluid outlet (20) adapted for communication with the source of hot (or heated) water, all inlets and outlets also being in communication with the cavity (13) provided within the valve body (12), said cavity (13) being provided with an insert (24) in a sealing relationship with an inner surface of the said cavity (13), said insert (24) having a central bore (42) and also defining flow passages and being configured to direct the flows of hot fluid entering the cavity (13) via the hot fluid inlet (18) and cooled fluid entering the cavity via the cooled fluid inlet (16), the flow passages defined by the said insert (24) interacting with moveable closure means to selectively permit, restrict or prevent the flows of hot fluid and cooled fluid into the cavity (13), and mixed fluid and return fluid out of the cavity (13), said moveable closure means being temperature-reactive and/or manually operable.
Abstract translation: 一种水温调节阀（10），包括具有空腔（13）的阀体（12），在该腔体中可以发生流体混合，并且设置有适于与源连通的热流体（或加热水）入口（18） 热（或加热）水的冷却流体入口（16），适于与使用混合流体进行加热的设备连通的冷却流体入口（16），适于与使用混合流体进行加热的设备连通的混合流体出口 ，以及适于与热（或加热）水源连通的返回流体出口（20），所有入口和出口也与设置在阀体（12）内的空腔（13）连通，所述腔（13） ）设置有与所述空腔（13）的内表面密封关系的插入件（24），所述插入件（24）具有中心孔（42）并且还限定流动通道，并且构造成引导 热流体经由热流体入口（18）进入空腔（13）并冷却 流体通过冷却的流体入口（16）进入空腔，由所述插入件（24）限定的流动通道与可移动闭合装置相互作用，以选择性地允许，限制或防止热流体和冷却流体流入空腔（13） ）和混合流体并将流体从空腔（13）中排出，所述可移动闭合装置是温度反应的和/或可手动操作的。
