Description

[0001] SMART VALVE WITH GAS PRESSURE REGULATOR [0002]

The present invention relates to a smart type safety function integrating sensors, alarms, and transceivers to detect gas accidents in advance, and a smart type gas pressure control function that uniformly adjusts the gas pressure exiting the valve Valve.

The present invention relates to a gas sensor for detecting a gas leak in a valve, a gas remaining amount indicator and a temperature sensor for measuring the gas remaining amount and temperature of the container, an electronic tag, a GPS for recognizing position and theft, a transceiver, And a smart type safety device integrating an angle sensor for indicating a flashing light and a conduction is mounted on a valve to ensure safety.

In addition, the valve is equipped with a vertical or horizontal pressure regulating function composed of a diaphragm and a spring so that the flow rate varies depending on the opening and closing degree of the valve, so that the gas pressure regulator is screwed to the rear end of the valve Therefore, it requires a lot of installation space, eliminates damage due to careless handling in the distribution process, and reduces the possibility of gas leakage caused by many connecting parts.

In addition, various kinds of foreign substances flowing on the gap between the handle of the valve and the valve body are caught in the screw portion and the sealing portion, and in particular, water is impregnated to prevent the phenomenon of winter season, The present invention relates to a smart valve having a built-in gas pressure adjusting function.

A gas pressure regulator for supplying a prescribed pressure to the combustor by connecting a gas pressure regulator to the rear end of the valve and screwing the valve for gas inflow and outflow into the uppermost central axis of the conventional LPG container, And a combustion device is connected to the rear end of the gas pressure regulator.

Conventionally, since a valve and a gas pressure regulator are fastened to an LPG container by a screw, the number of connection parts increases, the risk of gas leakage increases, the number of assembly operations increases, productivity lowers, and cost increases.

In addition, since the valve is securely installed inside the cylindrical protector of the LPG container, the gas pressure regulator is exposed to the outside of the cylindrical protector. Therefore, when the container is conducted or collides with an external object, the valve and the gas pressure regulator are broken, There is a high possibility that the explosion and fire may be caused by the damper, and if the damper is damaged, the diameter of the connecting portion may be deformed and a normal discharge amount can not be guaranteed.

Also, since the gas pressure regulator protrudes from the center of the LPG container, there is a high risk that the center of gravity is shifted to one side, and when it is exposed to sunlight, the pressure adjustment due to gas expansion is difficult. have.

In addition, problems such as inability to operate or leakage of gas occur due to freezing of various foreign substances introduced into the axial gap between the handle of the valve and the valve body, sticking to the threaded portion and the valve seat, Respectively.

In addition, when the RFID electronic tag is attached to the inner diameter surface of the cylindrical protector of the LPG container with an adhesive, problems such as falling or melting due to sunlight or a heat source, and falling off easily by an external object have been raised.

In addition, the conventional LPG steel vessel can not measure the remaining amount of the gas before it is weighed, and there is no safety device that can notify the dangerous situation such as gas leakage through the vessel and the valve, temperature rise, conduction and theft of the vessel, Accidents occurred frequently.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and it is an object of the present invention to provide an LPG container having an outlet gas pressure adjusting function built in a valve, It is possible to eliminate the asymmetric center of gravity due to the protrusion of the regulator, to reduce the damage caused by sunlight and strong wind, to prevent foreign matter from entering into the screw feed portion and the valve seat of the valve, This is to solve the problem of inoperability or gas leakage.

In addition, smart type safety function that remotely provides users with information such as gas leakage, temperature change, gas remaining amount display, container conduction and theft generated from LPG containers and valves, and smart type Valve.

In order to accomplish the object of the present invention, in order to integrate the function of opening and closing the valve and the function of uniformly supplying the outlet gas pressure of the gas pressure regulator into one, the valve is fastened to the structure separated by the valve body at the upper side and the lower side, , And a cylindrical support tube is assembled in the space between the upper and lower valve bodies between the neck and the cylindrical stem, and the horizontal or vertical diaphragm is used to adjust the gas pressure, thereby reducing installation space, durability, sealing property, and cost The smart type valve is provided with a gas pressure adjusting function excellent in performance, assemblability, productivity, and the like.

In addition, a circular cover may be assembled to the rotary shaft of the upper end portion of the handle in order to prevent various foreign substances introduced along the axial direction between the handle and the valve body from being caught in the screw feed portion and the valve seat, The present invention provides a Smart type valve in which a hollow column having a concentric center axis is integrally formed on an outer diameter surface of an upper end portion of a handle to prevent foreign matter or water from being originally introduced.

In addition, a smart type valve with built-in gas pressure adjustment function is provided with a structure in which a smart type safety device integrated with various sensors and alarms including an electronic tag is detachably attached to a female screw formed by perforating a valve body at a right angle .

Since the valve opening / closing function and the outlet pressure adjusting function of the gas pressure regulator are integrally combined and installed inside the cylindrical protector of the LPG container, it is possible to reduce the size, weight, seal durability and reduction It is possible to expect that the problem of damaging the gas pressure regulator due to the assembly process, cost reduction, conduction phenomenon of the LPG container, and careless handling can be expected to be solved.

In addition, the structure in which the circular cover is separately assembled to have the concentric circular axis on the outer diameter surface of the upper end of the handle or the hollow column is integrally formed has a problem that the operation is impossible or the gas leakage occurs because the foreign matter or water is difficult to flow intrinsically. It is possible to expect an effect of eliminating the phenomenon of being frozen and inoperable.

In addition, a smart type safety device that can be attached to and detached from the valve body can be tightened with screws to provide various information such as gas leakage, remaining gas amount display, electronic history management, conduction and theft of the LPG container and temperature, .
