ABSTRACT:
An automatic adjustable vacuum bleed valve particularly, but not exclusively, for use with a suction box of a paper making machine. The valve defines a first chamber connected to the suction box. A second chamber extends within the body of the valve and is connectible to a vacuum source. A hollow cylindrical valve stem passes through the second chamber and has a stem valve secured thereto to seat in the port in a wall of the second chamber. A further valve is positioned concentrically with the valve stem and seats in an opening provided in the body. The further valve has a stem slidingly engaged in a lower end of the valve stem. An upper end of the cylindrical valve stem is flexibly connected to the valve body by an impervious diaphragm having opposed surfaces, one of which is exposed to atmosphere and the other exposed to the first chamber. The control flow of fluid, such as water, is introduced in the cylindrical valve stem. A restricting orifice is provided in the valve stem to restrict the flow of fluid and thereby control the pressure in the cylindrical valve stem to regulate the vacuum in the first chamber. The first and second chambers are in communication via the port in the second chamber housing.
