Description

A kind of temperature-decreased pressure reducer with isolating construction

Technical field

The utility model belongs to thermal power plant field, more particularly, to a kind of temperature-decreased pressure reducer with isolating construction.

Background technology

The effect of temperature-decreased pressure reducer is the steam that the steam of high parameter is reduced to low parameter.When steam power plant's heat supply is not enough, lead to Cross temperature-decreased pressure reducer direct heating.As shown in figure 1, the structure element of temperature-decreased pressure reducer is：Process controller and electronic hold Row mechanism two large divisions.Because temperature-decreased pressure reducer is chronically at stand-by state, process controller control electric operator keeps Regulating valve crack 7% or so, under this state by steam easily to the valve row of regulating valve into vibration, add valve temperature It is high (60 DEG C) Zuo You, and process controller is in pipeline top, long-term vibrated and high temperature injury, the control of process controller Circuit board and simulation potentiometer be highly prone to damage, it is out of hand to valve after damage, it is necessary to change very worthy circuit board and Other elements, also need after replacing by that could recover normal after debugging, expensive laborious.

Utility model content

In view of this, the utility model is directed to a kind of temperature-decreased pressure reducer with isolating construction, can will be excessively program control Device processed is separately positioned with electric operator, and process controller does not receive high temperature and vibration effect, helps to protect process controller Control board and simulation potentiometer, simple installation is safe and reliable.

To reach above-mentioned purpose, what the technical solution of the utility model was realized in：

A kind of temperature-decreased pressure reducer with isolating construction, including process controller and electric operator, it is described excessively program control Be provided with device processed for control the electric operator control board and simulation potentiometer, the process controller and The electric operator is separately positioned, and also including thread guide devices, one end of the thread guide devices and the process controller are electric Connection, the other end is electrically connected with the electric operator.

Further, the thread guide devices include the first attachment cap, the second attachment cap and insulated conductor, the process control Device electrically connects second attachment cap, and the electric operator electrically connects first attachment cap, first attachment cap and Second attachment cap is connected by the insulated conductor.

Further, the process controller is fixed on column, and the column is located at pipeline side.

Further, the electric operator passes through regulating valve connecting pipe.

Relative to prior art, the temperature-decreased pressure reducer with isolating construction described in the utility model has the advantage that：

One end connection procedure controller of thread guide devices, other end connection electric operator, realizes process control Device and electric operator are separately positioned, it is ensured that process controller is no longer installed on pipeline top, will not again be subject to high temperature and shake Dynamic influence, can effectively protect the control board and simulation potentiometer in process controller, and process controller to separate The other positions located outside pipeline are arranged on, are conveniently checked and is checked, and thread guide devices only include the first attachment cap, the second connection Cap and insulated conductor, with reasonable in design, using, to install simple and convenient, low cost, safe and reliable, economic etc. excellent Point.
