Abstract
The utility model relates to an adjusting value, in particular to an automatic adjusting value with high viscosity and medium fluid of grain shape, which is suitable for industries such as oil, chemical industry, metallurgy, electric power, paper making and food. The utility model is characterized in that the adjusting value consists of a value body 8, a tube-type value core 6, a piston actuator 5, a value seat 7, a connecting piece 4 and a sealing piece1, 2 and 3. The adjusting value enlarges the service range of the traditional pneumatic adjusting valve with the advantages of new flow-path, mass flow, integration, no outer leakage of medium and long service life. The utility model can realize proportional adjustment with a localizer and bi-level adjustment with a solenoid value.
Description
Technical field:
The utility model relates to a kind of modulating valve, and particularly a kind of automatic adjusting that can be applicable to the high viscosity to industry such as oil, chemical industry, metallurgy, electric power, papermaking, food, band particle media fluid is characterized in that: new stream, integrated.
Background technique:
Traditional pneumatic control valve, it is streamlined that the runner of valve body is S, its shortcoming is, the valve body flow resistance is big, the dead angle is arranged in the runner, can not be used for resisting medium and the fluid that contains suspended solid and particle media, the using scope of modulating valve is limited to, in addition, traditional pneumatic control valve is made up of pneumatic actuator and modulating valve body two large divisions, so its complex structure, high material consumption is also because there is external leakage in the sealing part of link and valve, to inflammable, the field of employment of explosive and harmful gas and important regulating loop, this class modulating valve is not too safe and reliable, so the new integrated modulating valve of stream is the important breakthrough of traditional modulating valve notion, is a kind of brand-new end effector of present process control system.
Summary of the invention:
The integrated modulating valve of the new stream of the utility model, as shown in Figure 1.Mainly provide a kind of high viscosity that can be widely used in industrial fields such as oil, chemical industry, metallurgy, electric power, papermaking, food, band particle media fluid and need in the safe and reliable process control system.The integrated modulating valve of this new stream can adopt following technological scheme to implement: this modulating valve is made up of valve body 8, tubular type spool 6, piston actuator 5, Sealing 1,2,3, link 4, valve seat 7, valve body is a Cast Steel, and two ends are connected with pipeline with the flange pattern.Tubular type spool and piston actuator are connected as a single entity, and place valve inner, and tubular type spool two ends connect Sealing 1, only flow at the tube valve in-core to guarantee medium, can not leak.Air chamber A, B and piston actuator, Sealing 2 form a pneumatic piston actuating mechanism at valve inner, make when the gas signal, can finish the switch motion of modulating valve.Link and Sealing 3 are connected in actuator top, are connected with positioning work piece as resetting shaft, and Sealing can guarantee that the air chamber internal air pressure is stable.Valve seat is fixed on valve inner, different Flow characteristics such as valve has linearity, opens soon in order to make, equal percentage, and the head of valve seat makes interconvertible structure.The integrated modulating valve of making according to technique scheme of new stream is compared with traditional modulating valve has following advantage: 1) new stream, big flow, because tubular type spool movement direction is consistent with the media flow direction, high viscosity medium and particle media can blocking pipes like this, the straight-through type valve pocket, no fluid dead angle, the fluidised form stably that more becomes keeps big Flow characteristics fully.2) integral type, piston actuator places valve inner, makes the keying speed of modulating valve reach soon to open, the requirement of quick closing valve, and integral type also makes modulating valve simple in structure, and movement speed is faster.3) long service life, because the movement direction of tubular type spool is consistent with the media flow direction, valve seat is motionless relatively during the modulating valve action, just spool relative movement, so frictional force is little, long service life, its time of movement 〉=1,000,000 time, still it has good sealing property, and operating life is 3 times of conventional valve.4) can be with manually-operable, when power source breaks down, can be with handwheel on the link, finish the manually-operable of modulating valve.5) leaking of no medium, because medium just flows at the tube valve in-core, no any possibility that leaks like this, just can relievedly be used the use occasion of inflammable, explosive and harmful gas and important regulating loop.Requirements of green environmental protection has more been satisfied in not leaking of medium.
Description of drawings: accompanying drawing 1, the new integrated modulating valve structural representation of stream.
Embodiment:
The working principle of the new integrated modulating valve of stream: as shown in Figure 1: after coming the signal of the 4-20mA (20-100Kpa) of self tuning regulator or DCS (process controller) output to be input to valve positioner, output 1 enters air chamber A, output 2 enters air chamber B, act on piston actuator 5, piston is moved right, because piston 5 is connected as a single entity with tubular type spool 6, so the tubular type spool is near valve seat 7, make valve obtain a new aperture, hence one can see that when input signal is 4mA, valve wide open, valve complete shut-down when signal is 20mA is finished the air to close action of modulating valve, link 4 is connected with positioning work piece, when modulating valve moves, give position feed back signal of positioning work piece, make the proportional adjusting relation of signal and valve opening, thereby can be continuously to being transferred medium to carry out Flow-rate adjustment, the automatic control of implementation procedure.
In sum, can realize ratio adjusting when new integrated modulating valve of stream such as adapted valve positioner, and when integrated modulating valve of new stream such as adapted solenoid valve, can realize the switching value control of regulating system regulating system.
