Изобретение относитс к бытовой газовой технике и может быть применено в качестве регул торов давлени дл баллонов со сжиженными углеводородными газами.The invention relates to household gas appliances and can be applied as pressure regulators for cylinders with liquefied hydrocarbon gases.

Известны регул торы давлени газа, состо щие из корпуса с входным и выходным штуцерами, чувствительного элемента и запорно-регулирующего органа , управл емого чувствительным элементом через рычажньм механизм 1 .Gas pressure regulators are known, consisting of a housing with inlet and outlet fittings, a sensing element and a shut-off and regulating body controlled by the sensing element through the lever mechanism 1.

Наиболее близким техническим решением к предлагаемому вл етс регул тор давлени , содержащий корпус с входным и выходным штуцерами, подпружинен-, ный чувствительный элемент, св занный с рычагом,и регулирующий орган.Регулирование расхода выходного давлени осуществл етс чувствительным элементом, который управл ет запорно-2о регулирующим органом за счет энергии газа 2.The closest technical solution to the present invention is a pressure regulator, comprising a housing with inlet and outlet fittings, a spring-loaded sensitive element connected to the lever, and a regulator. The regulation of the output pressure flow is carried out by a sensitive element that controls the valve 2o by the regulatory authority at the expense of gas energy 2.

Claims

The purpose of the invention is to increase the accuracy and reliability of the controller. The goal is achieved by the fact that in it the lever is made with a profiled surface associated with the regulator through a support roller, the lever support being mounted on the axis of the regulator and being adjustable. The support roller and the lever are placed in the vertical slits of the regulator and the body. FIG. 1 shows a longitudinal section of the proposed gas pressure regulator; in fig. 2 - the working profile of the lever. The gas pressure regulator consists of a hollow body 1 with an inlet 2 willow x: one with 3 fittings and a lid 4, between the flanges of which the sensitive element 5 is clamped, made in the form of an elastic membrane 1y pivotally connected to the lever. 6, abutting against the edge of the support 7 and the cooperating profile c. roller 8 mounted on the movable element of the regulator 9. The movable element of the regulator and the lever relative to the body are spring-loaded respectively by springs 10 A portion of the working lever profile ° provides significant movement of the movable element of the regulator when the output pressure reaches the nominal, the section 6c provides the locking force slight movement of the rolling element of the regulatory body. The regulator works as follows. Through the inlet fitting 2 and the gap between the seat and the movable element of the regulator, the gas enters the submembrane cavity of the housing 1 and, through its pressure on the sensing element, passes it through the fitting 2 to the consumer (gas appliance). The output pressure is regulated as follows: the output gas pressure changes the position of the sensing element 5 connected to the lever 6, which by its working profile interacts with the spring-loaded regulator 10. When the gas pressure reaches the nominal lever 6, under the influence of element 5, rotates at such a 5S angle that the contact with the roller of the regulator occurs at point 8. When the output pressure is higher than the nominal pressure, the contact point goes to the area fid - flushes the locking force and the movable member closes Regulator regulator, as a result, the outlet pressure falls and the lever reopens inlet schtutsera 2. By lowering the pressure below the nominal output starts operating portion 1a, i.e., the moving part of the regulator is moved by a large amount, dramatically increasing the gas flow through the opening of the inlet fitting. Due to the proposed profile, with small fluctuations in the outlet pressure, there is a significant change in the gas flow through the inlet port

2. It allows. when changing the inlet pressure (gas pressure in the cylinder) or changing the quality of the gas consumed, maintain the outlet pressure of the pressure regulator at a constant level and insulate the best conditions for the combustion of the gas. Pru7kina 10 ensures the contact of the roller of the regulatory body with the working profile of the lever. The spring 1I serves to return the lever to its original position and provides the required lever position depending on the outlet pressure. The position of the lever relative to the adjustable body is established by means of the support 7 through the opening of the outlet fitting. Thus, the application of the proposed device allows to simplify the manufacture, assembly, configuration, accuracy of regulation with an increased throughput of the gas pressure regulator. Claims I. The pressure regulator comprising a housing with inlet and outlet fittings, a spring-loaded sensing element associated with the lever, and a regulating member, which is equipped with a lever that has a shaped surface in order to improve the accuracy and reliability of the regulator. associated with the regulator through the support roller, and the lever support is mounted on the axis of the regulator and made adjustable.
