Description

Technical Field

[0001] The utility model relates to the technical field of pressure regulators, in particular to a safety performance self-test device for a gas pressure regulator. Background Art

[0002] The air inlet of the pressure regulator will be connected to the filter through a flange, and the pressure regulating equipment will be connected to the external natural gas pipe. The natural gas directly passing through the outside contains more liquid, mineral impurities and metal impurities that fall off the inner wall of the transmission pipe. Therefore, it needs to be filtered through the filter before entering the pressure regulator.

[0003] Since the natural gas transmission pressure inside the external natural gas pipeline is relatively high, it needs to be regulated by a pressure regulator before it can be transmitted to the user end. Therefore, the natural gas pressure that the pressure regulator inlet needs to withstand is relatively high. As the use time increases, the impact of the gas pressure will reduce the sealing of the interface. If the operator who inspects the pressure regulating equipment cannot find the leakage in time, the natural gas leakage will cause serious consequences. Utility Model Content

[0004] The purpose of the present application is to provide a gas pressure regulator safety performance self-test device to solve the problems raised in the above background technology.

[0015] The following elaborates on the preferred embodiments of the present utility model in detail with reference to the accompanying drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present utility model. The directional terms mentioned in the present utility model, such as "up", "down", "front", "rear", "left", "right", "top", "bottom", etc., are only references to the directions in the attached drawings. Therefore, the directional terms used are for explaining and understanding the present utility model, rather than for limiting the present utility model.

[0016] Such as Figures 1-4A gas pressure regulator safety performance self-inspection device shown includes a fixing ring 1 and a collecting box 3. The collecting box 3 is fixedly installed below the fixing ring 1. The fixing ring 1 is composed of two semicircular arc-shaped bent plates. The two ends of the bent plates are fixed together by bolts. The fixing ring 1 is fixedly installed on the flange outer wall of the gas pressure regulator air inlet. Baffles 2 are fixedly installed on the outer walls of both sides of the fixing ring 1. The baffles 2 are in the shape of arc-shaped bent plates. The inner wall of the baffle 2 fits the outer wall of the fixing ring 1. The inner wall of the baffle 2 is connected to the interior of the collecting box 3. The collecting box 3 is fixedly connected to the outer wall of the fixing ring 1 by bolts.

[0017] A movable plate 6 is movably installed inside the collection box 3, and a plurality of springs 10 are fixedly installed at the bottom of the movable plate 6, and one end of the spring 10 is fixedly connected to the bottom inner wall of the collection box 3. A circular hole is opened on the outer wall of the movable plate 6, and a guide rod 9 is fixedly installed on the bottom outer wall of the collection box 3, and the guide rod 9 passes through the circular hole opened on the movable plate 6. A magnetic plate 7 is embedded and installed on one side of the collection box 3, and the magnetic plate 7 is detachable.

[0018] A buzzer 5 and a warning light 4 are fixedly mounted on one side of the outer wall of the collection box 3. The buzzer 5 and the warning light 4 play the role of sounding an alarm and reminding the operator. Contactors 8 are fixedly mounted on the bottom inner wall of the collection box 3 and the bottom surface of the movable plate 6. The installation positions of the two contactors 8 correspond to each other. The two contactors 8 are connected to the warning light 4 and the buzzer 5 through electrical signals.

[0019] Embodiment: The air inlet of the pressure regulator will be connected to the filter through a flange, and the pressure regulating device will be connected to the external natural gas pipe. The natural gas directly passed from the outside contains more liquid, mineral impurities and metal impurities that fall off the inner wall of the delivery pipe, so it needs to be filtered by the filter before entering the pressure regulator. The fixing ring 1 is set on the flange connecting the pressure regulator inlet and the filter. If a leak occurs at the connection, the liquid and impurities will be driven by the gas pressure of the natural gas and spray outward. The baffle 2 can block most of the liquid and impurities. As the liquid and impurities flow on the curved surface of the baffle 2, they will eventually flow into the collection box 3. The liquid and impurities accumulate on the movable plate 6. The magnetic plate 7 can absorb the iron metal impurities in the impurities. If the connection is constantly leaking or leaking a large amount at one time, the liquid on the movable plate 6 accumulates to a certain weight, and the movable plate 6 is pressed down. The movable plate 6 slides downward through the guide rod 9, and the spring 10 is compressed and deformed. After falling to a certain height, the two contactors 8 contact and send out an electrical signal. Then the buzzer 5 and the warning light 4 are activated, and sound and light are emitted to remind the operator that the pressure regulator air inlet connection is leaking. The collecting box 3 and the fixing ring 1 can be assembled and disassembled by means of bolts.

[0020] It should be noted that the parts not involved in the present utility model are the same as the prior art or can be implemented by the prior art; various drives in the present utility model can be implemented by corresponding power structures such as air cylinders, oil cylinders, electric cylinders, motors, etc. in cooperation with connecting rods, guide rods, etc., and are not limited to the descriptions in the specification and the structures in the drawings.

[0021] The above embodiments only represent several implementation modes of the present utility model, and the descriptions thereof are relatively specific and detailed, but should not be construed as limiting the scope of the utility model patent. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
