Abstract

The utility model relates to an automatic cutting off safety pressure regulator for domestic liquefied petroleum gas, which is added with a timer composed of a main shaft, a spring leaf of a spiral spring, a gear, a housing, and a handle in the existing pressure regulator and in an upper shell of the pressure regulator of a connecting structure of a sequential machine of a shell, the shell, a gas inlet nozzle, a rubber pad, a push rod, a draw hook, a fixed rod, a diaphragm, and a pressure regulating spring. The automatic cutting off safety pressure regulator for domestic liquefied petroleum gas is connected with the fixed rod by a steel cable, and the other end is connected with a guide groove wheel which is fixed onto the timer. When the timer is opened, the steel cable can loosen the fixed rod, and the pressure regulator can normally work. When the timer is stopped, the steel cable can tension the fixed rod, and the pressure regulator can be closed. The automatic cutting off safety pressure regulator for domestic liquefied petroleum gas can realize the timed and automatic cutting off.

Description

The household liquified petroleum gas safe pressure governor of dying automatically

The utility model belongs to the gas appliance equipment technical field, the safety type pressure governor that specifically a kind of household liquified petroleum gas can be died automatically.

Household liquified petroleum gas pressure governor is that household liquified petroleum gas user is used for playing the staple product of decompression between liquified petroleum gas cylinder and the combustion gas tool always, and is widely used owing to possess decompression, voltage regulation performance.But, from the situation that each liquid gas user uses, occur often closing liquid gas because of forgetting, cause burning kitchen tools, cause fire, weight person causes gas leak, leads to house and ruins the tragedy that the people dies.Its main cause except that subjective with gas accidentally, objectively pressure governor lacks and uses due to the function that can cut off source of the gas after a period of time automatically.Therefore, the combustion gas user generally needs a kind ofly both can reduce pressure, and can timing automatic die again, relatively the new-type pressure governor of safety.

The purpose of this utility model will provide a kind of safety type pressure governor exactly, can solve pressure governor effectively and lack the problem that timing automatic is died, to guarantee the safety of people's lives and properties.

To achieve these goals, the utility model is taked following technological scheme: structural design is made of three parts, and the one, timer adopts the clockwork spring type mechanical timer, by clockwork spring sheet [4], mechanical gear [3], handle [1], main shaft formations such as [2], adjustable interval of time is 0 to 2 hour; The 2nd, coupling piece is made of guide groove wheel [5], wire rope [6]; The 3rd, pressure governor is chewed [13], shell formations such as [14] by pressure adjusting spring [7], diaphragm [9], fixing rod [8], drag hook [10], push rod [11], rubber pad [12], air inlet.Timer is installed in the regulator hole of pressure governor top [14], and coupling piece is between timer and pressure governor internal fixation bar.

Owing to adopted technique scheme, the utility model is made up of three parts, timer is durable in use, coupling piece is simple and reliable, the pressure governor decompression is nimble, and three part worker cooperations constitute an integral body, can realize the pressure governor timing automatic function of dying fully, total deft design, compactness, attractive in appearance.The utility model can be installed on the cylinder for liquefied gas and link with gas appliance, also two ends can be made improvements slightly to be installed on the pipeline gas.Has extensive applicability.

Description of drawings:

Accompanying drawing is the utility model concrete structure schematic representation.

Embodiment:

Accompanying drawing has been described an embodiment of the present utility model, is described in detail referring now to accompanying drawing:

These family expenses liquefied petroleum gas (LPG) safe pressure governor of dying automatically, constitute by pressure governor, timer and three parts of coupling piece, can clearly be seen that from structural representation, timer works the time of determining, pressure governor plays decompression and pressure stabilization function, coupling piece is tied timer and pressure governor, and pressure governor cuts out and opens.When stopping the position of [0] when timer is in, coupling piece is because the rotation of guide groove wheel [5] has driven wire rope [6] bar [8] that is strained and fixed, make on the fixing rod [8] and carry, block air inlet by fixing rod drive drag hook [10] promotion push rod [11] and chew [13], make pressure governor be in closed condition, at this moment open gas cylinder and also do not have gas and pass through pressure governor.When timer forwards certain position (within 0 to 2 hour) to by 0, drive guide groove wheel [5] rotation by timer, thereby wire rope [6] is unclamped, the power that acts on the fixing rod [8] disappears thereupon, fixing rod [8] is promoted downwards by spring [7], drives drag hook [10] push rod [11] is removed, and air inlet is chewed [13] and is opened, open steel cylinder valve gas and both can chew and enter pressure governor, carry out decompression automatically, voltage stabilizing control by pressure governor by air inlet.When timer drives when rotating back to the position of stopping down at spring sheet [4], then can make guide groove take turns [5] and rotate and take up wire rope [6], up to wire rope [6] bar [8] that is strained and fixed, make it to close air inlet and chew [13].Below both finished the life cycle of the pressure governor of once dying automatically.Obviously, combustion gas tool air feed be made, the timer of pressure governor must be opened earlier, at this moment the timing automatic function of dying is unlocked, and when the people leaves the gas appliance that just using after a period of time because of carelessness, pressure governor can cut off source of the gas automatically, stop air feed, guaranteed safety with gas.
