Abstract

A compact control valve for regulating the pressure in a duct is provided. The flow of liquid from the duct into a by-pass passage 7 is controlled by a valve member 9 which is urged away from a valve seat 8 when the pressure in the duct is above a pre-set limit. The movement of the valve member 9 is controlled by a pressure- sensitive diaphragm 11 which is connected to the valve member 9 by a housing 12 containing a spring 13, whose tension is adjustable and which urges the valve member 9 against the valve seat. The pressure in a closed chamber above the diaphragm 11 is controllable. Thus, the pressure prevailing in the duct before the valve member will open is governed by (i) the relative areas of the diaphragm and the value seat, (ii) the pressure differential across the diaphragm and (iii) the tension in the spring, the latter two influences being adjustable to give the desired upper pressure limit in the duct. <IMAGE>

Description

Изобретение относится к автомати-. ке, в частности к регуляторам давления.The invention relates to automatic. ke, in particular to pressure regulators.

Цель изобретения -- уменьшение габаритов регулятора. 5The purpose of the invention is the reduction of the size of the regulator. 5

На фиг. 1 представлен регулятор давления, разрез; на фиг. 2 -· то же. вид сбоку; на’ фиг. 3 - то же, вид сверху.In FIG. 1 shows a pressure regulator, section; in FIG. 2 - the same. side view; in FIG. 3 - the same, top view.

Регулятор давления содержит кор- Ю пус 1, входную 2 и выходную 3 полости, клапан 4, полый шток 5, мембрану 6, пружину 7 задания, стержень 8 с выступом 9, бурт 10 полого штока. 5.The pressure regulator comprises a housing 1, an inlet 2 and an outlet 3 cavities, a valve 4, a hollow rod 5, a membrane 6, a task spring 7, a rod 8 with a protrusion 9, a shoulder 10 of the hollow rod. 5.

На конце 11 стержня 8 выполнена резь- 15 ба, крышка 12 закреплена на корпусе . 1 и образует с ним полость 13 управ-: ляющего давления.At the end 11 of the rod 8, a thread 15 ba is made, the cover 12 is fixed to the housing. 1 and forms a cavity 13 of the control pressure with it.

Регулятор давления работает следующим образом. 20The pressure regulator operates as follows. 20

Давление жидкости, действующее на клапан 4, уравновешивается силами, создаваемыми на мембране 6, и силами пружины 7 задания. Состояние равновесия определяется предваритель— ным напряжением пружины 7 при изме·' няющихся значениях давления.The fluid pressure acting on the valve 4, is balanced by the forces created on the membrane 6, and the forces of the spring 7 of the job. The equilibrium state is determined by the preliminary stress of the spring 7 at varying pressure values.

При увеличении давления полый шток 5 через бурт 10 сжимает пружину 7. При смещении клапана 4 дросселирование пропускного канала уменьшается, и количество вытекающей через него жидкости увеличивается, вследствие чего значение давления в направлении свободного потока устанавливается на заданную величину.With increasing pressure, the hollow rod 5 compresses the spring 7 through the shoulder 10. When the valve 4 is displaced, the throttling of the passage channel decreases and the amount of liquid flowing through it increases, as a result of which the pressure value in the direction of free flow is set to a predetermined value.

Установка рабочего давления производится поворотом стержня 8, что означает изменение предварительного натяжения пружины 7, или же эта установка может быть осуществлена косвенным путем посредством создания давления газа, направленного против слоя, создаваемого мембраной, или же в результате использования обеих возможностей. Пневматическая регулировка снижает максимальное давление, определяемое силой пружин, до желаемого минимального значения.The working pressure is set by turning the rod 8, which means changing the pre-tension of the spring 7, or this setting can be carried out indirectly by creating gas pressure directed against the layer created by the membrane, or as a result of using both possibilities. Pneumatic adjustment reduces the maximum pressure, determined by the force of the springs, to the desired minimum value.
