Abstract: A dual-function valve with pressure adjustment and temperature control functions comprises a valve body having a first cool water inlet, a first hot water inlet, two first mixing water outlets, a first chamber and a second chamber; the first chamber and second chamber being communicated by a second cool water channel and a second hot water channel; the second chamber being communicated to the first mixing water outlets through a water outlet channel; a pressure balance device for adjusting the water pressures of hot water and cool water; the pressure balance device being installed in the first chamber; and a temperature control device installed in the second chamber; the temperature control device adjusting the amount of water flowing into the second chamber by expansion and contraction of the mixing water of hot water and cold water; and the temperature control device being connected to the first chamber in parallel.

Abstract: A check valve has a sleeve threaded to a seat so that an adjusting rod, a valve rod and a spring can be installed therein. The sleeve has a water inlet and a plurality of through holes so that when water flows into the valve body from the water inlet of the sleeve, the pressure of the water flow will press the valve rod to move upwards. Then water will flow out from the through hole of the sleeve. When the valve rod moves downwards, the pressures of the water flow and the spring will seal the water inlet to prevent the water flows reversely. Furthermore, the valve body has an integral structure. No part will lose in maintenance. Moreover the assembly speed will be increased.
