The inner side of the regulator is provided with a hole plate which can regulate the setting point, a valve, and a valve core; the inner part of the actuator is provided with a film box, a membrane, an actuator lever, and a reset spring. The utility model is characterized in that a pressure sensor and an intelligent instrument are connected with control wires on one side of the upstream high pressure and the downstream low pressure of the inner valve of the regulator; the intelligent instrument can display the sizes of the flow quantity; the opening of the clearance of the hole plate and the valve core can be fed back and regulated; the constant flow quantity can be kept; the heating of the thermal substation and the user inlet can be kept, and the flow quantity of the domestic water can be kept to be the constant value.
Description
The utility model belongs to a kind of regulating device of heating system, particularly is applied to the direct acting type regulating device of heating system.
In the existing heating system thermal substation, generally not having device for installing and adjusting, is that moving realization of armrest regulated.Therefore, the flow distribution inequality appears in heating system, the hydraulic misadjustment of room temperature skewness and thermal misadjustment phenomenon, in order to address the above problem, adopted enlargement discharge, improve that water pump is exerted oneself and measure such as user installation water pump, its result can not solve hydraulic misadjustment and thermal misadjustment problem, has also increased heating load and has carried the power consumption of thermal medium.At present some thermal substation begins to adopt microcomputer monitoring and monitoring, but because no regulating measure and quality of workers are not high, and present stage the cost height, therefore, result of use is not good.At present, domestic limited-production direct-operated regulator does not have the function that shows flow again.Chinese patent " equalizing valve and intelligent instrument specially for same thereof " (patent No. 88203650.5) provides a kind of family curve and valve opening and valve coefficient relation by valve flow, valve two end pressure drops, valve coefficient to fit to the intelligence instrument that equation deposits programmable calculator in, this instrument is made up of differential pressure pick-up, differential pressure transmitter, A/D converter, microcomputer central processing unit and display, to valve upstream and downstream differential pressure, be convertible into electric signal and shown.As shown in Figure 3, differential pressure pick-up is selected the KYC-G piezoresistive pressure sensor for use, and differential pressure transmitter is made of 2DW232 standard of precision voltage and LM308 precision operational-amplifier, the resistance signal of differential pressure pick-up output is converted linearly to the voltage signal of 0～2V; After the voltage transitions that A/D converter is exported transmitter becomes binary-coded decimal, send into central processing unit, the microcomputer central processing unit is core with 80C310PU, can handle the parameter and the instruction of differential pressure signal and keyboard input, and calculated flow rate and valve opening, simultaneously keyboard and display are managed; Display adopts light-emitting nixie tube, can show parameters such as differential pressure, flow, valve opening; Keyboard can be imported differential pressure measurement, flow rate calculation, and valve aperture, valve opening, measuring unit's conversion waits instruction; Primary power is made of+the 5V primary power No. 1 battery of 4 joints, uses for complete machine; Accessory power supply converts primary power to ± the 5V power supply, uses for differential pressure pick-up, differential pressure transmitter, A/D converter.
The purpose of this utility model is, a kind of novel self-operated type intelligent display flow regulator is provided, and this regulating device can be controlled automatically and show flow, and is simple in structure, reliable, so that be widely used for the discharge that keeps constant at middle-size and small-size thermal substation.
Self-operated type intelligent display flow regulator of the present utility model, form by regulator, actuator and intelligence instrument, be provided with orifice plate, valve and the spool of an adjustable settings point in the regulator, change the gap aperture of orifice plate and spool, can limit resistance to flow, set flow; Be provided with bellows, diaphragm, actuator bar and back-moving spring in the actuator, diaphragm is accepted the pressure signal that regulator high pressure one side transmits, and promotes the actuator bar by diaphragm, the upper and lower displacement of control spool, can change the gap aperture of orifice plate and spool, change resistance to flow, regulate flow; Intelligence instrument fits to equation by the family curve of valve flow, valve two end pressure drops, valve coefficient and valve opening and valve coefficient relation and deposits programmable calculator in and constitute, it is characterized in that, upstream high pressure one side of valve and following friendly low pressure one side are connected with pressure transducer and intelligence instrument with control line in regulator.
The course of action of self-operated type intelligent display flow regulator of the present utility model is: when fluid as shown by arrows direction pass through valve, the position control flow and the differential pressure of orifice plate and spool, Fully-balanced spool is not subjected to the influence of hydrodynamic pressure fluctuation, because upstream pressure acts on the outside surface of metallic bellows, and downstream pressure acts on the inside surface of metallic bellows.The differential pressure actuate actuators of orifice plate, the high pressure of orifice plate upstream passes to the bottom of bellows by control line, and the low pressure in orifice plate downstream passes to bellows top by valve rod and actuator bar.Raise as flow, the outer differential pressure of orifice plate is raise, thereby diaphragm also raises, diaphragm and spool begin the direction motion to valve closing, the position of the flow set point of adjusting until reaching.
The utility model has the advantages that intelligence instrument can show the size of flow, and feedback actuate actuators and the regulator gap aperture of regulating orifice plate and spool, keep constant flow, overcome the shortcoming that existing flow control valve does not have the flow Presentation Function.Be applicable to the flow of regulating non-corrosive liquid and gas medium in heating system and the power source factory device, keeping thermal substation and user entry heat supply and domestic hot-water's flow is steady state value.
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 flow regulator.
Fig. 2 is the internal structural map of regulator and actuator.
Fig. 3 is the schematic diagram of existing intelligence instrument.
As seen from the figure, self-operated type intelligent display flow regulator is made up of regulator 1, actuator 2, is provided with the orifice plate 3 of an adjustable settings point in the regulator, valve 4 and spool 5, and the gap aperture of change orifice plate and spool can limit resistance to flow, sets flow; Be provided with bellows 6, diaphragm 7, actuator bar 8 and back-moving spring 9 in the actuator, diaphragm is accepted the pressure signal that the one side transmission of regulator high pressure comes, pass through diaphragm, promote the actuator bar, control the upper and lower displacement of spool, can change the gap aperture of orifice plate and spool, change resistance to flow, regulate flow, it is characterized in that upstream high pressure one side of valve and downstream low pressure one side are connected with pressure transducer 11 and intelligence instrument 12 with control line 10 in regulator.
