Abstract

Изобретение относитс к гидроавтоматике и может быть использовано в гидроприводах различного назначени дл регулировани расхода жидкости. Целью изобретени вл етс повышение точности регул тора за счет термокомпенсации, а также повышение точности за счет компенсации жесткости упругой пластины. Регул тор расхода содержит корпус 1, стакан 2 с пр моугольным окном 3, над которым расположена упруга пластина 4, одним концом прикрепленна к стакану 2, а другим опирающа с на упор 5, который поджимаетс пружиной 6 к опоре 7, изготовленной из материала с коэффициентом линейного расширени , большим коэффициента линейного расширени материала упора 5. Упруга пластина 4 имеет форму трапеции и закреплена со стороны меньшего основани , причем соотношение оснований трапеции 1:2, толщина пластины на 1/3 ее длины равна 1/2 толщины остальной части упругой пластины. 1 з.п. ф-лы, 4 ил.The invention relates to hydraulics and can be used in hydraulic drives for various purposes to control the flow of fluid. The aim of the invention is to improve the accuracy of the regulator due to thermal compensation, as well as to improve the accuracy by compensating for the rigidity of the elastic plate. The flow regulator comprises a housing 1, a tumbler 2 with a rectangular window 3, above which an elastic plate 4 is located, at one end attached to the tumbler 2, and the other resting on the anvil 5, which is pressed by the spring 6 to the support 7, made of a material with a factor linear expansion, greater than the linear expansion coefficient of the material of the stop 5. The elastic plate 4 has the shape of a trapezoid and is fixed on the smaller base side, the ratio of the base of the trapezium is 1: 2, the plate thickness is 1/3 its length equal to 1/2 the thickness of the rest of the elastic second plate. 1 hp f-ly, 4 ill.

Description

Claims

Claim

1. The flow regulator comprising a housing with input and output channels, with a glass placed in it, the bottom of which is facing the input channel, and on the cylindrical surface of the stack a rectangular window is made, over which an elastic plate is installed, jq one end of which is fixed in the housing, and the other is connected in contact with a stop, characterized in that, in order to increase the accuracy of the regulator due to thermal compensation, the stop 5 is made in the form of a rod with a base installed between a spring and located in a closed cavity, which is: valuable in the bottom of the glass, a support made of a material with a linear expansion coefficient greater than that of the stop material,

2. The regulator pop. ^ distinguishing with the fact that, in order to increase accuracy by compensating for the rigidity of the elastic plate, the elastic plate is made in the form of a trapezoid with a base ratio of 1: 2 and is fixed from the side of the smaller base, the latter having a thickness of 1/3 of the length of the elastic plate equal to 1/2 the thickness of the rest of the elastic plate.
