Abstract
The utility model relates to a radiating anti-annealing butterfly valve device; a radiating anti-annealing butterfly valve and a valve (8) device are connected on the connecting pipeline of an oil gas conveying pipeline (1) through a connecting flange disk (2); the valve device is characterized in that the valve (8) is not closed but opened when oil gas is on fire in the tank body or pipeline; simultaneously, the radiating anti-annealing butterfly valve is closed, and the oil gas on fire flows through the radiating anti-annealing butterfly valve device. A circulating radiating fin set (3) is adopted outside the radiating anti-annealing butterfly valve device; a butterfly valve integration capable of rotating for 90 degrees is adopted inside the radiating anti-annealing butterfly valve device; the butterfly valve integrally consists of a rotating shaft (5), a butterfly valve ring (6) and an anti-annealing screen (7) fixed on the butterfly valve ring (6) and is controlled by a handle (4). The radiating anti-annealing butterfly valve device and the valve (8) form a dual-functional main body capable of ensuring the normal transmission of oil gas and preventing the oil gas from fire disaster.
Description
Affiliated technical field
The utility model is specifically related to the technical field of valve switch commonly used on the pipeline of safety in transportation and storage petroleum gas and jar case.
Background technique
Known to the inventor, present valve both domestic and external has: (hard sealing) ball valve series, (bellows) gate valve series, butterfly valve series, (to folder) safety check series, (steel ball) stop valve series, (steel) stopcock series, modulating valve series, reduction valve series, (waterpower) control valve series, power station valve series, drain valve series, discharging valve series, the common feature of these valves is that passing through of liquids and gases opened and block in control, also do not have a kind of to allow liquids and gases to open and block, the valve that does not allow kindling material to pass through comes out.
Summary of the invention
The utility model is to realize like this.Described a kind of heat dissipation type anti-backfire butterfly valve valving comprises: transportation pipe line 1, mounting flange 2, groups of fins 3, Handle of butterfly valve 4, butterfly valve rotating shaft 5, butterfly valve ring 6, backfireproof net 7, valve 8.Eigen is: a kind of heat dissipation type anti-backfire butterfly valve valving is on the connecting line of transportation pipe line 1, connect the heat dissipation type anti-backfire butterfly valve device by mounting flange 2, it is characterized in that: the heat dissipation type anti-backfire butterfly valve external body adopts around groups of fins 3; The inner butterfly valve integral body that adopts one rotatable 90 ° of heat dissipation type anti-backfire butterfly valve body, butterfly valve integral body by rotating shaft 5 and butterfly valve ring 6 and on butterfly valve ring 6 fixing backfireproof net 7 forms, and control by employing handle 4; The rotation butterfly valve apparatus of heat dissipation type anti-backfire butterfly valve and valve 8 constitute one and ensure the normal use of oil gas and the dual functions main body of prevention and control oil gas fire.
Description of drawings
Accompanying drawing is a kind of heat dissipation type anti-backfire butterfly valve valving schematic representation, transportation pipe line 1, mounting flange 2, groups of fins 3, Handle of butterfly valve 4, butterfly valve rotating shaft 5, butterfly valve ring 6, backfireproof net 7, valve 8 among the figure.
Embodiment
Embodiment is described in further details the utility model below in conjunction with accompanying drawing, a kind of as shown in drawings heat dissipation type anti-backfire butterfly valve valving is on the connecting line of transportation pipe line 1, connect heat dissipation type anti-backfire butterfly valve and valve 8 devices by mounting flange 2, its characteristics are: when oil gas in tank body or pipeline during breaking out of fire, it or not throttle down 8, but open valve 8, fast close simultaneously heat dissipation type anti-backfire butterfly valve, allow aflame oil gas from the heat dissipation type anti-backfire butterfly valve valving, flow through, block burning things which may cause a fire disaster simultaneously and pass through, and oil gas is dispelled the heat herein.The heat dissipation type anti-backfire butterfly valve external body adopts around groups of fins 3; The inner butterfly valve integral body that adopts one rotatable 90 ° of heat dissipation type anti-backfire butterfly valve body, butterfly valve integral body by rotating shaft 5 and butterfly valve ring 6 and on butterfly valve ring 6 fixing backfireproof net 7 forms, and control by employing handle 4.The rotation butterfly valve apparatus of heat dissipation type anti-backfire butterfly valve and valve 8 constitute one and ensure the normal conveying of oil gas and the dual functions main body of prevention and control oil gas fire.
Claims (1)
