Description
Direct-action regulator of differential pressure
The direct-action regulator of differential pressure with the expense limiter
DN 15 to 50, PN 25
The direct-action regulator of differential pressure of RD 122 D is the fittings intended for maintenance of constant value of pressure difference on the set equipment. It is reached at the expense of use of a membrane which is affected by entrance and output pressure on the equipment. Fluctuations of a membrane are transferred to a valve cone, and at increase of a difference of pressure there is a closing of the valve. Thanks to the cone unloaded on pressure, value of differential pressure does not depend on pressure on the valve.
The direct-action regulator of differential pressure with the limiter of an expense of RD 122 P is the fittings intended first of all for restriction of the maximum expense that is provided by means of couple of cones, one of which is regulated by the consumer on the required value, and the second copes pressure difference influences of a membrane. The deviation of a membrane is transferred to a cone and at increase of a difference of pressure the valve is closed. The cones unloaded on pressure, guarantee reliable function and stability of the established value, in all range of static and differential pressure.
In cases when value of the set pressure is in area which derates values of the used spring, it is necessary to establish a spring with a suitable range.
Complete with regulators pulse tubes for accession to selections of pressure from the pipeline are standardly delivered.
Application
Regulators are intended for work in usual warm and goryachevodny lines in heat supply, and also in branches with some characteristics of the environment, for example in refrigerating and a klimotekhnik. The maximum pressure difference on the regulator should not exceed 1,6 MPas.
Regulators of differential pressure with restriction of an expense find the application where it is necessary to limit a nominal expense of the environment via the device at the same time as maximum, for example, restriction of power of the water folding device at start, etc.
Working environments
Regulators of the RD 122 series are used in the equipment where the adjustable environment is water, air or pairs of low pressure to 0,4 MPas. Besides, are suitable for the cooling mixes and other nonaggressive liquids, and also gaseous environments in the range of temperatures from +2oC to +150oC. Sealing surfaces of throttle system are steady against usual dirt and impurity of the environment, but in the presence of abrasive impurity it is necessary to install in the pipeline in front of the valve the filter, for ensuring long-term reliable functionality and tightness.
