Abstract

An automatic shutoff valve according to the present invention comprises: a vertical hole formed along a center shaft of a horizontal body; an open/close function unit bent in a perpendicular direction to the vertical hole to control entry and exit of gas; an automatic shutoff function unit disposed on a same axial line of the open/close function unit; and a safety valve and a remanent gas measurement device disposed at a location rotated 90 degrees from a height of the aforementioned components. The automatic shutoff valve opens/closes by a circular packing compressed by a dual circular sheet which rotates in a direction perpendicular to an end of the vertical hole. Whenever an integrated handle rotates to a left and a right from an identical position, the open/close function unit moves back and forth by a hollow cross recess formed on an inner circumference of a cylindrical screw-type slider which controls open/close operation and a cross-shaped protrusion unit formed on an outer circumference of the integrated handle, which are engaged with each other. Therefore, the circular packing and the dual circular sheet perform opening, closing, and sealing functions. An electronic tag and a wireless antenna are installed in an internal hollow space of the integrated handle, and thus safety management of the automatic shutoff valve can be carried out remotely. Additionally, the automatic shutoff function unit reduces gas filling time and flow loss, and automatically blocks gas emission if a rubber hose mounted on an entry/exit hole of the automatic shutoff function unit escapes to secure safety. Furthermore, the remanent gas measurement device displays an amount of gas remaining in a cylindrical container containing liquefied petroleum gas based on measured data for a gas pressure of the cylindrical container to provide convenience and safety in gas usage.

Description

{AUTOMATIC SHUTOFF VALVE}

The present invention relates to an automotive single-ended valve for a liquefied petroleum gas pressure vessel, and more particularly, to a motor-operated single-valve valve for a liquefied petroleum gas pressure vessel, more specifically, a vertical hole formed along a central axis of a horizontal body and a vertical hole formed at a right angle, And the gas remaining amount measuring instrument is mounted on the same axis of the open / close function section and the vehicle end functional section, and at a position rotated by 90 degrees from the same height, respectively. And a circular packing which is pressed onto a double circular sheet formed so as to be continuous with the valve body.

Wherein the hollow cruciform groove formed in the inner diameter portion of the cylindrical threaded slider, which functions as an opening and closing function, is engaged with the cruciform protrusion formed on the outer diameter portion of the integral handle when the integral handle is always rotated from the same position to the left and right, The circular packing and the double circular sheet have an opening / closing sealing function, and an electronic tag and a wireless antenna are installed in the inner hollow portion of the integral handle to enable remote safety management of an automobile single-

In addition, in the automobile end function unit, the filling time and the flow loss of the gas are reduced, and when the rubber hose fastened to the outflow inlet is released, the gas discharge is automatically blocked to ensure safety.

The present invention also relates to an automotive single-ended valve for a liquefied petroleum gas container, which provides convenience and safety of gas use by visually displaying the remaining amount of gas in a cylindrical container based on data obtained by measuring the gas pressure of the cylindrical container.

Conventional automotive single-end valves for liquefied petroleum gas containers have a number of automotive single-ended valves for tightening with cylindrical vessels and screws. Since the opening and closing portions for opening and closing the inflow and outflow of the threaded portion and the gas are installed on the same axial line in the vertical direction, The height of the cylindrical protective safety structure for protecting the valve is also increased.

In addition, since the brass stem and the plastic handle are screwed together for opening and closing the automotive single-ended valve, when the screw is loosened or loosened for a certain period of time, the compression sealing force between the circular seat and the round packing is weakened, Since the two pins are installed in the body in the lateral direction so that the upper and lower reciprocating movements of the brass stem can be controlled by the upper and lower stoppers, the complicated assembling process increases the cost burden and all these components use brass products Since the circular sheet and the round packing are squeezed when they are in contact with each other, there is a lack of elastic restoring force in the long-used circular packing, resulting in a rapid permanent deformation, a decrease in sealing durability, The two o-rings that are installed on the outer circumference of the cylindrical hanger are used for the installation hole This increases the sealing pressure was falling and durability problems.

In addition, the flow gap formed in the sliding space between the cylindrical slider and the stopper bolt is structurally narrow in order to automatically shut off the gas flow when the rubber hose fastened by the screw to the outflow inlet is separated to secure safety, The flow loss due to the flow of gas through the two square holes formed in the circumferential direction of the circumferential direction is high, and the installation of the two O-rings has a problem that the overall length is increased and relatively heavy.

In addition, since the conventional cylindrical steel container can not measure the remaining amount of gas charged, it is difficult to measure the remaining amount of gas, so that the liquefied petroleum gas is filled in the pressure vessel and supplied. The problem was raised.
