Abstract

Una bomba de doble diafragma operada por aire provista de un equipo de válvula de aire que permite que el dispositivo neumático se mueva según unpatrón rectangular que reduce en gran medida el costo y el número de piezas requeridos paradich a válvula de aire. El recinto principal de la bomba estámontado sobre una base de fluidos a la cual se conectan las lineas de fluidos. Esto permite quitar la bomba para repararla retirando una serie de sujetadoresbásicos tales como tuercas ypernos sin que sea necesario quitar los accesorios de fluidos de la base. En consecuencia, en caso de mal funcionamiento de labomba, esta puede reemplazarse al tiempo que los accesorios de fluidos permanecen intactos. Están tambiénprovistos conduc tos adicionales para cadacámara de aire para la operación por medio de una válvula solenoide operada desde el exterior. Se utiliza una construcción de válvula de retención de unapieza, la cual contiene un disco central desellado que cuenta con u na serie de elementos de guía que se extienden a partir de dicho disco en forma radialaxial, cada uno de los cuales tiene un diámero exterior que permite que calce en forma precisa en una cavidad cilíndrica y cada uno delos cuales cuenta conuna se rir de unas accionadas por resorte que se extienden en forma axialmente opuesta al disco de sellado y que sirven para fijar la válvula de retención enposición cerrada.An air operated double diaphragm pump provided with an air valve kit that allows the pneumatic device to move in a rectangular pattern which greatly reduces the cost and number of parts required for the air valve. The main pump enclosure is mounted on a fluid base to which the fluid lines are connected. This allows the pump to be removed for repair by removing a number of basic fasteners such as nuts and bolts without the need to remove fluid fittings from the base. Consequently, in the event of a pump malfunction, the pump can be replaced while the fluid accessories remain intact. Additional conduits are also provided for each air chamber for operation by means of an externally operated solenoid valve. A one-piece check valve construction is used, which contains an unsealed central disc that has a series of guide elements extending from said disc in a radial axial fashion, each of which has an outer diameter that allows it to precisely fit into a cylindrical cavity and each of which has a spring-loaded set of rings extending axially opposite the sealing disc and serving to secure the check valve in a closed position.
