Abstract
The utility model relates to a gravimetric-type intelligent displaying flow-regulating device which is composed of an adjustor and an actuator, wherein, the inner part of the adjustor is provided with a valve body, a valve and a valve core; the inner part of the actuator is provided with a diaphragm box, a diaphragm, an actuator rod and a balance corrugated pipe; the upper part and the lower part of the diaphragm are respectively communicated with the upper part and the lower part of the valve. The utility model is characterized in that the actuator rod extends from the lower end of the diaphragm box and is connected with a spring and a nut to set the pressure difference value, and the upper side and the lower side of the diaphragm in the diaphragm box are connected with a pressure sensor and an intelligent meter by a control wire. The utility model has the advantages of simple structure and high reliability, and can automatically control the pressure difference and display the pressure difference. The utility model is suitable for the pressure difference control and the hydraulic balance of heat power stations, and the portal heating nets and living hot water pipe nets of users.
Description
The utility model belongs to a kind of regulating device of heating system, particularly a kind of direct acting type regulating device that is applied to heating system.
In order to make the heating medium parameter of sending into heating system, hot water supply system and industrial enterprise's process equipment remain on setting, for being remained under the declared working condition, the thermal substation of handling heating agent and system equipment move, reduce the staff of thermal substation, improve heating quality, should install self-checking device.
Existing differential pressure control valve, the differential pressure that can regulate liquid in the heating system or gas, keeping the differential pressure of thermal substation and user entry heat supply and domestic hot-water's pipe network is steady state value.China has produced static variable valve, and not producing as yet has the self-power differential pressure regulating device.
The purpose of this utility model is, a kind of differential pressure regulation device of self-operated type intelligent display is provided, and can control differential pressure automatically and show differential pressure, and is simple in structure, reliable, keeps constant differential pressure and hydraulically balanced automatic control problem in the middle-size and small-size thermal substation to solve.
Self-operated type intelligent display differential pressure regulation device of the present utility model, form by regulator and actuator, be provided with valve body, valve and spool in the regulator, be provided with bellows, diaphragm, actuator bar and balance corrugated tube in the actuator, being communicated with the upstream and downstream of valve respectively up and down of diaphragm, it is characterized in that, the actuator bar stretches out the bellows lower end, is connected with spring and nut, to set differential pressure value, both sides about the bellows interior diaphragm are connected to pressure transducer and intelligence instrument with control line.
Intelligence instrument is made up of differential pressure pick-up, differential pressure transmitter, A/D converter, microcomputer central processing unit and display, to the differential pressure of valve upstream and downstream, is convertible into electric signal and is shown.
The course of action of self-operated type intelligent display differential pressure regulation device of the present utility model is: when fluid as shown by arrows direction when the valve, the clearance control fluid differential pressure of valve and spool, the spool that has the balance corrugated tube, be not subjected to the influence of hydrodynamic pressure fluctuation, only the amount of spring compression of stretching out bellows by the actuator bar demarcating diaphragm up and down the differential pressure value of both sides controlling the gap of valve and spool, change differential pressure, need to adjust the position of nut; Intelligence instrument by control line connects can show differential pressure value.
Self-operated type intelligent display differential pressure regulation device of the present utility model, have the following advantages: intelligence instrument can show differential pressure value, the differential pressure of confession, backwater that guarantees the user controlled or equipment is constant, and the differential pressure control stabilization when certain certain value, just is convenient to realize the constant control to flow.
Be applicable to the differential pressure of regulating non-corrosive liquid and gas medium in heating system and the power source factory device, keeping the differential pressure of thermal substation and user entry heat supply and domestic hot-water's pipe network is steady state value, realizes the pipe network water dynamic balance.
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is the structural representation of self-operated type intelligent display differential pressure regulation device.
Fig. 2 is the internal structural map of regulator and actuator.
Fig. 3 is the schematic diagram of intelligence instrument.
As seen from the figure, self-operated type intelligent display differential pressure regulation device, form by regulator 1 and actuator 2, be provided with valve body 3, valve 4 and spool 5 in the regulator, be provided with bellows 6, diaphragm 7, actuator bar 8 and balance corrugated tube 9 in the actuator, being communicated with the upstream and downstream of valve respectively up and down of diaphragm, it is characterized in that, the actuator bar stretches out the bellows lower end, be connected with spring 10 and nut 11, to set differential pressure value, both sides about the bellows interior diaphragm are connected to pressure transducer 13 and intelligence instrument 14 with control line 12.
Intelligence instrument is made up of differential pressure pick-up, differential pressure transmitter, A/D converter, microcomputer central processing unit and display, to the differential pressure of valve upstream and downstream, is convertible into electric signal and is shown.
