Abstract:
This invention relates to a tap assembly (10) for a liquid vessel (12), having an overfill protection device and a float controlled mechanical or magnetic level gauge (18). A single float (42) actuates a stem (57) of the overfill protection device as well as a rod (20) of the level gauge (18). The rod (20) of the level gauge (18) has one end movable linearly in a valve body bore (62) and carrying a permanent magnet (64) for actuating a magnetic level indicator (22). In one embodiment a crank mechanism may be provided between a float lever (44) and the rod (20) of the level gauge (18) to cause the rod (20) to effectuate a swinging movement and simultaneously displace the rod (20) longitudinally to cause linear displacement of the permanent magnet (64) in the valve body bore (62). In another embodiment the rod may be actuated by a cam to cause axial displacement thereof without swinging motion.

Abstract:
Esta válvula de retención para recipientes contenedores de gas licuado, concretamente de las instaladas en la boca de los recipientes contenedores de gas licuado en su utilización industrial y doméstica, la cual es de cierre automático y de apertura mediante un dispositivo empujador incorporado en una válvula de regulación que, cooperando con un manorreductor, controla el caudal de gas en su suministro a un aparato de consumo, estando dotada la bola (23) del obturador de bola (3) de un apéndice de corredera (24) que es perpendicular al plano de obturación y presenta una sección recta que impide su giro y que coincide, en forma deslizante, con una ventana de guía (25) practicada en el fondo (22) de un cuerpo de resorte (6) de la caja de soporte (2).
Abstract:
The invention relates to a valve to be placed on a container, especially on a bottle in which pressure has built up. Said valve comprises a valve housing (1) in which at least one valve seat (23, 24) is provided. A valve seat (23, 24) which is independent of the pressure inside the bottle is located between a plunger (28) and the content of the bottle in a manner so as to be linked with the plunger (28). An accumulator (39) whose force can be varied presses against the other end of the plunger (28). The plunger (28) slides in a cylinder compartment (27) in the valve housing (1), said compartment being closed by a spring housing (34) that comprises an axial stepped bore (35) in which particularly the accumulator (39) whose force can be varied is received. Said accumulator (39) encircles an intermediate piece (36) as the helical spring and is supported on a head (37) of the intermediate piece (36) and on the plunger (28). A plunger compartment (26) upstream of the plunger (28) communicates with an outlet via a bore (42) in the intermediate piece (36), said outlet (51) being provided with a check valve (43).
Abstract:
Overfill protection device consisting of a main valve (10) and an auxiliary valve (18). This is suitable in particular for tanks to be filled with liquid, such as an LPG tank. There is a float device (22) (fig 2) that closes the auxiliary valve (18) when a desired fill level is reached. The main valve (10) consists of a piston or membrane (11) that on one side is loaded by the inlet pressure and on the other side is connected via a restriction (12) and the auxiliary valve (18) to the interior of the tank. When the auxiliary valve (18) is closed the pressure increases and an equal pressure prevails on either side of the valve body of the main valve, which leads to closure of the main valve. According to the invention the auxiliary valve is closed by means of a rod (21) attached to the float device. This closing movement is a positive pull movement. The float device is provided with a counterweight (25) (fig 2).
Abstract:
The present invention relates to a container valve for liquefied petroleum gas (LPG) and, more particularly, to a gas container valve capable of previously preventing a dangerous situation by making a rear pressure of the container and the inner pressure of the container the same at the time of opening the container. The valve for the LPG according to the present invention comprises : a valve body in which a gas flow hole, a main gas guide hole and an exhaust guide hole are provided; a handle having an opening/closing member for selectively opening and closing the main gas guide hole; a pressure controller, for making a rear pressure of the valve and an inner pressure of the container the same, having a gas exhaust hole to exhaust a very small amount of the gas and a gas exhaust blocking member to control a gas exhaust; and an overflow gas controller for opening/closing the main gas guide hole according to a movement of the pressure controller.
Abstract:
The invention relates to a gas valve, in particular, having electromagnetic actuation and comprising a valve closing element (14). This valve closing element controls a flow of gas from an inflow side to an outflow side (34) and interacts with a valve seat (26), which is formed on a valve plate (62) having at least one flow-through opening that leads to the outflow side (34). The invention provides that the inflow side is joined downstream to an inner (22) and to an outer (20) pressure area. These pressure areas (20, 22) are located upstream from the valve seat (26), and the inner pressure area (22) has an axial pressure channel (19) of the valve closing element (14) that exits on the free face (24) of the valve closing element (14), and the outer pressure area (24) surrounds the valve closing element (14).
