摘要： A mixing valve (10) includes a manifold (12) defining a hot fluid inlet (18), a cold fluid inlet (14), a temperature-controlled fluid outlet, and a cold fluid outlet. The cold fluid inlet is in fluid communication with the cold fluid outlet, and the cold fluid inlet and the hot fluid inlet are in fluid communication with the temperature-controlled fluid outlet. The manifold further defines a mixing chamber (22) for mixing of cold fluid from the cold fluid inlet and hot fluid from the hot fluid inlet. Mixed fluid from the mixing chamber (22) is delivered to the temperature-controlled fluid outlet. A temperature-controlled device (26) associated with the hot fluid inlet (18) controls the volume of flow from the hot fluid inlet to the mixing chamber. The mixing valve further includes a one-way check valve (28) located between the hot fluid inlet and the cold fluid outlet for limiting flow of hot fluid to the cold fluid outlet.

摘要： A backflow prevention assembly has a unitary housing with a passage therethrough, two threaded regions formed in an inner surface of the unitary housing, and two valve assemblies positioned in the passage to prevent fluid flow in a direction. Each valve assembly has an annular mount having a threaded outer surface that engages one of the threaded regions on the inner surface of the housing. The threads can be formed by placing a die having a thread on an outer surface thereof in contact with an inner surface of the unitary housing, and pressing on the outer surface of the housing.
摘要翻译：防回流组件具有整体式壳体，其具有穿过其中的通道，形成在整体式壳体的内表面中的两个螺纹区域以及定位在通道中以防止流体沿一个方向流动的两个阀组件。每个阀组件具有环形安装件，该环形安装件具有螺纹外表面，该螺纹外表面接合壳体内表面上的螺纹区域中的一个。螺纹可以通过在其外表面上放置具有螺纹的模具而形成，该模具与整体式壳体的内表面接触并且压在壳体的外表面上。
