Imported three-way valve

Imported three-way valve Overview: regulating valve for regulating the field of industrial automation process control media flow, pressure, temperature, level and other process parameters. The automated system control signal, automatically adjusting the valve opening, in order to achieve the medium flow, pressure, temperature and level of regulation. Regulating valves are usually composed by electric actuators or pneumatic actuator and valve body in two parts. Straight trip mainly through single-seat formula and two straight two-seater, which has a large flow capacity, imbalances do small and stable operation characteristics, it is usually particularly suitable for high flow, high pressure drop and low leakage applications. Rotary mainly: V-type electric control valve, electric butterfly valve, ventilation valve, butterfly valve and so on. Cv flow capacity value is one of the main parameters regulating valve selection, the definition of control valve flow capacity is: When the control valve fully open, the pressure differential across the valve is 0.1MPa, fluid density of 1g / cm3, the hour the number of valves regulate the flow of the flow path, called flow capacity, also known as flow coefficient to Cv, said unit t / h, Cv values ??calculated liquid. Flow capacity Cv value based on the size of look-up table, you can determine the control valve nominal diameter DN. In the modern factory automatic control, plays a very important role in regulating valve, the plant's production depends on proper distribution and control the flow of liquids and gases. These control whether energy exchange, or simply reduce the pressure vessel feed, we need to complete certain final control element. Final control element can be considered automatic control of the "strength." Between high energy level function regulator low energy welterweight and control the flow of fluid required for the implementation of the final control element to complete the necessary power amplification. Imported three-way valve flow characteristics: adjust the flow characteristics of the valve, is maintaining constant pressure differential across the valve condition, the relationship between the media flows through the valve of the relative flow with its opening. Control valve flow characteristics are linear features, such as the percentage of three properties and parabolic characteristic. Percentage characteristic regulating valve, control valve linear characteristic, parabolic nature of the control valve. SIGNIFICANCE OF THREE Fluence feature are as follows: relative stroke and relative flow (1) the percentage of properties (logarithmic) equal percentage characteristic is not a linear relationship between changes in traffic itinerary changes every point in the stroke unit caused by this point The flow rate is proportional to the percentage change in the flow rate is equal. So it has the advantage of traffic hours, small flow changes, the flow is large, the flow rate changes, that is a different opening, with the same regulation accuracy. (2) the relative stroke linear characteristic (linear) linear flow characteristics and relative linear relationship. Flow changes caused by changes in unit stroke is unchanged. Flow, the flow of small changes in relative value, traffic hour, the flow variation in relative value. (3) by two parabolic characteristic flow is proportional to the stroke changes, with intermediate characteristics generally linear and equal percentage characteristics. As it can be seen from the analysis of the three characteristics of its performance in terms of adjustment to the percentage of properties for the best, its regulatory stability, regulation performance. The parabolic characteristic off than good regulation performance linear characteristic, may vary according to applications requirements, the selection of any kind of flow characteristics. (4) flow coefficient Kv Kv valves regulate the flow coefficient is an important parameter adjustment valve, which reflects the capability of adjusting the valve through the fluid, which is regulated volume valve. According valve flow coefficient Kv calculation, you can determine the selection valve caliber. In order to properly select valve diameter, must correctly calculate the regulator valve rated flow coefficient Kv values. Valve rated flow coefficient Kv is defined as: under specified conditions, the pressure differential across the valve is 10Pa, fluid density of lg / cm, flows through the valve at nominal stroke in m / h or t / h of flow rate number. Imported three-way valve installation and maintenance: control valve is very commonly used in industrial production and particularly important control equipment, it works or not directly related to the production of the entire apparatus is normal or not. Now, with the control valve technology advances, the manufacturer and the form of the control valve very numerous, have different functions, the following highlights various types of valve prior to installation and commissioning should pay attention to common problems. 1, adjust the purchase before the valve is installed in the incoming inspection test valve is a very important part to confirm whether the arrival of the control valve to meet the design requirements. Technical requirements for each valve shall meet the design requirements, but incoming inspection should be focused to check the following several items. 2, Body / Trim Size The contents include: valve type, valve type, nominal diameter, seat size, spool form, flow characteristics, leakage levels, body material, valve material, Seat Material , CV value, flange sealing surface of standard grade size and form, as long as there is the same as found discrepancies content and design should be designed to identify and recognize. 3, the implementing agency should check the main part of the contents of this actuator model, type, function form, spring range, air supply pressure. 4, the positioning part of this mainly inspection locator input signal, air pressure, electrical and gas source interface size and explosion-proof rating, proof of which shall not be less than the design grade level requirements. 5, annex carefully clean design valve according to the technical requirements of the annexes, such as filter regulator, limit switches, solenoid valves, hand wheel, special tools. Test content of the above can clean up, measuring instruments, view the nameplate and special detection instruments (such as flange and bolt material can be identified by spectral analysis) and other methods to achieve. 6, the valve body of the hydrostatic test pressure test include leakage test pressure test and spool valve is fully closed. Under normal circumstances, when the design pressure exceeds valve 10MPa, the valve pressure test must be carried out to test the body itself and its pressure on the valve cover.
