Description

[0001] Portable Natural Gas Vent Device [0002]

The present invention relates to a movable natural gas dissipating device, and more particularly, to a movable natural gas valve or block valve that can move safely and conveniently in a field, To a mobile natural gas dissipating device having an improved structure so as to greatly reduce noise during the process of dissipating and dissipating the natural gas.

Generally, natural gas is liquefied natural gas (LNG) which is transported from overseas origin, stored in storage tank, compressed to high pressure, and then converted to gas state through vaporizer, It is supplied to a city gas company or a power plant in each region through a station. The supply station is equipped with ball valves for supplying and shutting off gas between various facilities and supply pipes for supplying natural gas at a constant pressure

(Piping) replacement and replacement of valves (piping) after constructing branch and bypass lines in piping that has already been supplied in connection with improvement and replacement of piping and valves for existing gas supply, ) And valve internal leakage check. In this process, the ventilation hose is connected to the working section which cuts off the relevant section and the gas of the section to dissipate in the air.

Noise is generated in the process of gas dissipation, which hinders the work environment and causes damage to the operator's hearing loss.

As a prior art for preventing the noise during the gas dissipation process, there has been proposed a method of reducing the noise level of a gas in a predetermined position on a gas piping connection pipe, as disclosed in Korean Patent No. 10-0962523 entitled " A diffuser pipe installed at an upper end of a vertically installed dissipation tower at a height of 20 to 30 m and a first chamber through which a gas discharged through a plurality of discharge holes formed in the diffuser pipe are introduced, An inlet cover installed to form a second chamber on an upper portion of the first sound absorbing member; an outer cover installed to form a discharge passage on an outer side of the inlet cell and the first sound absorbing member; A rainwater cover provided so as to prevent rainwater from flowing into the inlet cell, an inner iron having a plurality of sound absorbing holes formed at predetermined intervals, A sound absorbing material protection cloth attached to one side face of the sound absorbing material, a mesh network of a mesh type installed on an outer face of the sound absorbing material protecting cloth, and a plurality of And a perforated plate formed with a discharge hole and installed at the outer side of the wire net.

Other prior art related to conventional gas dampers is disclosed in Korean Registered Utility Model No. 20-0483344 entitled "Portable Gas Dissipation Silencer" (Registered on Apr. 24, 2014) A muffler for reducing noise, the muffler comprising: a housing having a closed space having an inlet and an outlet; a plurality of multi-attack plates partitioning the inside of the housing into a plurality of chambers and having a plurality of holes; A first diffuser tube having one end connected to the piping and the other end supported through any one of the multi-attack plates and having a plurality of holes formed on an outer circumferential surface thereof, a first diffuser pipe having one end connected to the other end of the first diffuser pipe, A second diffuser tube having a large diameter and a plurality of holes formed in the outer circumferential surface thereof and the other end supported at the outlet side; And, it is coupled to the upper end of the discharge pipe and the end cap having a plurality of holes are formed.

However, there is a restriction that the natural gas should be dissipated to the atmosphere at a height of 5 m or more from the ground according to the contents of Table 6 of the Urban Gas Business Act enforcement regulations when gas air is discharged for inspection and maintenance of ball valves and natural gas supply facilities.

Conventionally, the prior art is to improve the noise generated in the gas dissipation process. However, in the case of the supply station, the constantly installed defense tower satisfying the above-mentioned regulations is installed. However, There is a disadvantage in that it is not equipped with a defense device in the case of natural gas air discharge for checking gas supply facilities.
