Abstract
The utility model discloses a multifunctional adjusting stop valve which is capable of automatically adjusting pressure to achieve constant pressure, conveniently adjusting stopping, very high in safety performance, small in starting and closing torsion, easy to dismount and maintain and long in service life and has the non-returning function. The multifunctional adjusting stop valve comprises an auxiliary spring, a control ball valve and a copper tube. The middle and the bottom of the valve rod are provided with drain holes connected with one another. The auxiliary spring is arranged between an adjusting valve clack and the lower end face of a lower valve cover, and an upper valve cover is internally provided with a water inlet hole and a water outlet hole which can be replaced by each other. A control chamber is formed between the upper valve cover and the valve rod, and can guarantee that the water pressure is balanced and stable. When the pressure of the outlet water is too high, a returning tube can be used for enabling water to flow back to the control chamber, the pressure of the outlet water is reduced quickly when the auxiliary spring plays a role of buffering, and the constant pressure is kept. The water outlet of a valve body has the non-returning function, and when the valve is closed, the valve can be conveniently connected with a pressure measuring device or a temperature measuring device, and water is effectively prevented from flowing back.
