Abstract

The invention relates to automation, in particular to shut-off and control valves for liquefied gas cylinders for automatic control and maintenance of gas pressure and its flow. The controller contains housing 1 with input 2 and output 3 unions, cover 4, sensing element 5, t gu 6, intermediate lever 7 mounted on axis 8, task spring 9, glass 10, stop-regulating member 11 mounted on axis 12, and the threaded sleeve 13. The intermediate lever is made T-shaped and is connected by one hinge with the lever of the locking regulator, a. others - with a sensitive element. At the same time, the ratio of the distance from the axis of rotation of the T-shaped lever to the plane of contact with the sensitive element to the distance from the axis of rotation of the T-shaped lever to the plane of contact with the lever of the locking regulator is greater than one. Installing the spring coaxially with the outlet nipple reduces the size of the regulator. 1 hp f-ly, il. i (Л С

The invention relates to automation, in particular, to stop and control valves for cylinders with liquefied petroleum gases.

The purpose of the invention is to reduce the overall dimensions of the controller.

The drawing shows a gas pressure regulator in the Open position.

The regulator includes a housing 1 with an inlet 2 and outlet 3 fittings and a lid 4. A sensing element 5 made in the form of an elastic membrane connected through 6 to 6 to an intermediate lever 7 mounted in the housing on an axis 8 The interstitial lever is T-shaped and a spring 9 of the task is installed in its groove, which abuts against the second end through the glass 10 into the body.

The T-shaped lever 7 is connected via a hinge to the locking and regulating body 11, which is connected to the body through the axis 12. To ensure adjustment of the parameters, through the output fitting, the locking and regulating body 11 is made composite.

The force of the screw 9 is adjusted by the threaded bushing 13 installed in the outlet of the outlet fitting. This solution allows you to easily adjust the controller to the specified parameters, for example, with a screwdriver. . . . It can be seen from the diagram that the gear ratio of the lever mechanism is determined from the expression

Claims (1)

1. A gas pressure regulator, comprising a housing with inlet and outlet fittings, in which a sensing element is located, a shut-off and regulating member mounted on the lever on the side of the inlet fitting, an intermediate lever and a reference spring, characterized in that overall dimensions, the intermediate lever is made T-shaped and is connected with one hinge with the lever of the valve and the regulating body, and the other with the sensitive element, while the ratio of distance 7 can be increased gear ratio mechanism, and therefore locking the usi-dz „from the axis of rotation of the T-shaped lever, without increasing the size of the regulator. The regulator works as follows. . Under the action of the spring 9, the pressure regulator in the initial position is open. Through the inlet nozzle 2 and the throttle gap between the valve and the valve 11, the gas enters the sub 50 ha to the plane of contact with the sensing element to the distance from the axis of rotation of the T-shaped lever to the plane of contact with the lever of the regulating body is more than a unit. the membrane cavity of housing 1, exerts its pressure on the sensitive element .5 and through the output VNIIPI Order 1296/45 Circulation 866 2, the Regulator according to claim 1, which is the fact that the task spring is installed coaxially with the outlet fitting and connected to one of the arms of the T-shaped lever. Subscription 0 five 0 five 0 five 0 The knob 3 is fed to the burners of the gas apparatus (not shown). With an increase in the inlet pressure or a decrease in the flow through the fitting 3, the pressure in the body cavity increases and raises the sensitive element 5, which rotates the intermediate lever 7 around the axis 8 through the hinge of the rod 6 and intervening lever 7, compressing the spring 9, turns the locking valve II around the axis I .. The throttling gap between the inlet fitting and the shut-off regulator is reduced, and the pressure increase ceases. The implementation of the intermediate lever is T-shaped and connected by one hinge with the lever of the locking and regulating organ, and the other with the sensitive element at a given ratio of shoulders, as well as the transfer of the spring of the driver mechanism into the submembrane cavity, simplifies the gearbox lever ratio, i.e. the capacity of the controller, without increasing its size. Invention Formula 1. A gas pressure regulator, comprising a housing with inlet and outlet fittings, in which a sensing element is located, a shut-off and regulating member mounted on the lever on the side of the inlet fitting, an intermediate lever and a reference spring, characterized in that overall dimensions, the intermediate lever is made T-shaped and is connected with one hinge with the lever of the shut-off and regulating organ, and the other with the sensitive element, while the ratio of the distance s „from the axis of rotation of the T-shaped lever „„ From the axis of rotation of the T-shaped lever ha to the plane of contact with the sensing element to the distance from the axis of rotation of the T-shaped lever to the plane of contact with the lever of the regulating body is more than a unit. 2, the Regulator according to claim 1, which is the fact that the task spring is installed coaxially with the outlet fitting and connected to one of the arms of the T-shaped lever.
