This article introduces you to the solenoid valve product features and elements of knowledge which it? Mainly from the technical characteristics, choice points, and construction and installation points summarize some knowledge about the solenoid valve

Knowledge.

(A) leakage blocking must, easy to control internal leakage, safe to use. Internal and external leaks are endangering safety elements. Other automatic control valve stem extends usually by electric, pneumatic

, Hydraulic actuators control spool rotation or movement. This should resolve the long-action valve stem seals for external leakage problem; solenoid valve is used only for the electromagnetic force

Sealed in the electric control valve separated from the magnetic core inside the casing to complete, there is no dynamic seal, so easy to block leakage must. Electric valve torque control difficult, prone to internal leakage, even

To pull off the stem head; solenoid valve structure type is easy to control internal leakage, until reduced to zero. Therefore, the use of special safety solenoid valve, in particular for corrosive,

Toxic or high temperature media.

(2) system is simple, they take the computer, low prices modest. Solenoid valve itself is of simple structure, the price is low, compared to other types of valve actuators are easy to install

Maintenance. More significant is composed of automatic control system is much simpler, the price is much lower. Since the solenoid valve is a switching signal control, and industrial computer connection is very square

Stools. In today's widespread use of computers, an era of declining prices, the solenoid valve advantage is even more apparent.

(3) Action Express, power tiny, lightweight form factor. Solenoid valve response time can be as short as a few milliseconds, if the pilot solenoid valve can be controlled in a few

Ten milliseconds. Since forming the circuit, than the other automatic control valve more responsive. Properly designed solenoid valve coil power consumption is very low, an energy-saving products; also do

Simply trigger action, automatically maintain valve position, usually is not power. Solenoid valve small size, saving space and light and beautiful.
(4) regulation accuracy is limited, apply medium is limited. Solenoid switch is usually only two states, the spool can only be in two extreme positions, can be adjusted continuously

, (Trying to break a lot of new ideas, but also are in the pilot trial stage) so the adjustment precision is also subject to certain restrictions.

Solenoid valve on the media cleanliness have higher requirements, including granular media can not be applied in the case of impurities must first filtered. In addition, viscous media can not apply, and

Moreover, the product is suitable for a particular medium viscosity range is relatively narrow.

(5) model and diverse, widely used. Although deficiencies solenoid valve, the advantages are still very prominent, so we designed a wide variety of products to meet a variety of non-

The same needs, extremely versatile. Solenoid valve technology advances are also centered on how to overcome the deficiencies, how to better play the inherent advantages and expand.

First, the product choice points

A solenoid valve for the selection of the main control parameters diameter, nominal design, the medium temperature range allowed, the interface size.

2 solenoid valves with solenoid push on and off, often used the following two 40mm caliber control, especially used for switched off

Or conversion of gas, liquid and roads.

3 valve sealing performance is assessing the merits of the main indicators of quality of the valve one. Valve sealing performance mainly include two aspects, namely, leakage and leakage. Within

Leakage refers to the closure member between the valve seat and sealing of the media reach. Leakage refers to the parts of the stem packing leak, leaks in the mouth as well as parts of the gasket body because casting

Defects caused by the leak. Leakage is allowed to happen.

4 solenoid valve main advantages of small size, reliable operation, easy maintenance, the price is cheap. Note that when you choose according to process requirements normally open or normally closed

.

Second, the construction and installation points

1 valve installation location, height must comply with the direction of the mouth meet the design requirements, should be firmly connected tightly.

2 valves must be visually inspected prior to installation, the valve plate should be consistent with existing national standards GB12220 "Universal Valve logo" requirement.

Third, the implementation of standards

Product standards

GB/T13927-92 "universal valve pressure test"

JB/T8528-1997 "common type valve electric device technology."

GB12220-89 "Universal Valve logo"

Engineering standards

GB50243-2002 "Ventilation and Air Conditioning Engineering Construction Quality Acceptance"

GB50242-2002 "Building Water and Heating Engineering Quality Acceptance"
