Self-latching liquid/gas control valve
(57) Abstract:The device relates to a self-regulating liquid/gas valves and can be used in plants for bottling soft drinks for interrupting the flow of fluid under pressure would push the gas. Deep in the hole of a spring-loaded shut-off organ, freely installed slidable in the intermediate space of the body, placed freely moving additional stop valve. When filling in the intermediate cavity gas to the level of the slits made in the spring loaded shut-off body, additional shut-off body moves before landing on the saddle, made on the inner wall of the housing from the outlet. 3 C.p. f-crystals, 7 Il. The invention relates to the field of valve and can be used in plants for bottling soft drinks for interrupting the flow of fluid under pressure would push the gas.Known control valve, comprising a housing with inlet and outlet openings and an intermediate cavity between them, the first saddle, made on the inner wall of the housing side inlet ø the relatively first seat elongated locking body with a blind hole, the open side of the outlet housing, and the hole diameters are equal, and a slot through which a blind hole is in communication with the intermediate cavity.A disadvantage of the known technical solution is that when the level has sunk to the level of push gas it will flow through the valve.The objective of the invention is to prevent penetration eject gas supply system of the liquid when the magazine is empty.The technical result is achieved by the fact that in the proposed self-latching liquid/gas regulating valve, comprising a housing with inlet and outlet openings and an intermediate cavity between them, the first saddle, made on the inner wall of the housing from the inlet, and freely mounted slidable in the intermediate cavity spring-loaded relative to the first seat elongated locking body with a blind hole, the open side of the outlet housing, and the hole diameters are equal, and a slot through which a blind hole is in communication with the intermediate cavity, according to the invention, the slot is located upstream relative to the pen housing bore of a spring-loaded locking member freely placed additional shut-off body with the ability to interact with the second seat when filling gas of the intermediate cavity to the level of the location of the slot.In Fig. 1 shows a schematic depiction of a setup for bottling soft drinks; Fig. 2 is an axial slit self-latching valve in the off position; Fig. 3 - self-latching valve in the condition of transmission fluid, and Fig. 4 - self-latching valve in the condition of the locking strip of Fig. 5 is a cross-section on the line III-III of Fig. 2; Fig. 6 is a cross-section on the line IV-IV of Fig. 2; Fig. 7 is a General view of a standard connector Assembly with self-latching valve.As shown in Fig. 2, a self-liquid/gas control valve 1 includes a housing 2 with the top cover 3, has an input mounting flange 4 with the inlet 5 and outlet mounting flange 6 to the outlet 7. The housing has an intermediate cavity part 8 of smaller diameter and part 9 of larger diameter with the first saddle 10. The second saddle valve 11 is made on the cover 3. Within part 9 of the intermediate cavity is located with the possibility of free movement of elongated locking body 12 with a blind hole 13, the open side of the outlet 7 in the form of a channel 14 with a diameter equal to the diameter of the hole 7. The open part of the channel 14 is made with a group of protrusions 15 in the form of a comb. The outer side of the locking body 12 snabzheniem the saddle 10.Inside the channel 14 posted by free movement of the additional locking body 18 of the spherical shape. The locking body 18 of the valve may be a steel ball bearing or made any other way. The second saddle valve 11 is designed in such a way that it is locked in the body 18, when it occupies the position shown in Fig. 4.The bottom of the closure body 12 is a slot 19 for the connection duct part 8 with an opening 13 below the seat 10 of the valve. Shut-off body 12 of the valve is pressed to the seat 10 by means of a weak spring 10.Self-latching liquid/gas control valve 1 operates as follows. The input flange 4 is connected to a source of fluid under pressure would push the gas, and the output flange 6 is connected to regulate the output valve. After opening the output valve through the valve 1 begins to pass the fluid flow, under which the shut-off body 12, overcoming the action of the spring 20 away from the seat 10 of the valve. The liquid begins to flow freely from the system through valve 1, as shown by the arrows in Fig. 3. When the liquid is depleted (see Fig. 4/ under on the Ativ ball 18, will close them saddle valve 11. Thus, it will prevent the gas from entering the outlet 7 and a joint course as long until you resume submission only liquids.As already mentioned, the most advantageous to apply a valve according to this invention in plants for bottling beverages, namely, containers for beer or syrups. In Fig. 7 shows the standard connector Assembly 21 that contains the installation part 22 beer container, the operating handle 23, the inlet fitting 24 for feeding CO2and the fitting 25 for beer. Shut-off body 12 with a pre-mounted on it a spiral spring 20 is easily inserted into the cavity of the outlet fitting 25 Assembly 21 and is closed by a cover 26 of the discharge tube 27. Thus, a standard connector Assembly 21 can be easily converted into liquid/gas somesuperclass device without any modifications to the system.Although illustrated and described above, embodiments of the invention, specialists in the art obvious its various modifications.The invention is not limited to the described variants of its implementation or its separate parts, possible otklonenie is Rusisa valve can also operate in a horizontal position, if the ball 18 is mounted to the opposing spring, to correct its movement under the influence of gravity. 1.
