Abstract
The invention relates to a combined valve for precisely measuring and controlling a flow rate. The combined valve comprises a valve and an intelligent electric valve executing mechanism. The valve is provided with the intelligent electric valve executing mechanism. The combined valve is characterized in that a wind differential pressure transmitter is connected with the valve in parallel; a positive-pressure joint and a negative-pressure joint of the wind differential pressure transmitter are respectively connected with a first connecting pipe and a second connecting pipe, and the first connecting pipe is connected with an inlet inner cavity of the valve; and the second connecting pipe is connected with an outlet inner cavity of the valve. The combined valve for precisely measuring and controlling the flow rate, disclosed by the invention, has the advantages of simple, compact and reasonable structure, high measurement precision, good stability and remarkable energy saving effect, integrates functions of measuring and controlling the flow rate and completely meets the requirement on the precision of air flow rate instant regulation of a sewage treatment precise aeration system.
Description
Technical field
The present invention relates to a kind of flow and accurately measure the control combination valve, specifically be used for having on the accurate aerating system of sewage treatment the multi-functional executive component of accurate measurement and control air mass flow, belong to the mechanical structure technical field.
Background technique
In existing technology, in the accurate aerating system of sewage treatment, all adopt control valve and gas flowmeter to be installed in series, flowmeter is positioned near on the export pipeline of control valve, the detected signal feed back of flowmeter is given intelligent automatic control system, by control system will with the corresponding order input control valve of technological requirement, make control valve action realizing instant adjusting, thereby satisfy in the sewage treatment process each stage the different requirements of air mass flow to flow.This flowmeter belongs to the thermal type flowmeter, its principle is the variation of trying to achieve gas flow by the temperature variation of detecting head, because the complexity of the motion of the pressure air in the pipeline and the nonuniformity of temperature distribution, determined the measuring accuracy of this type of flowmeter low, poor stability, can't satisfy the accuracy of accurate aerating system, not reach desirable energy-conservation requirement flow control.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, thereby provide a kind of flow accurately to measure the control combination valve, it integrates the function of measurement, control flow rate, precision height, good stability.
According to technological scheme provided by the invention, flow is accurately measured the control combination valve and comprised valve, intelligent electric valve actuator, and the intelligent electric valve actuator is installed on the described valve, and feature is: the wind differential pressure transmitter links to each other with valve is in parallel; The positive and negative crimping mouth of described wind differential pressure transmitter connects first respectively to be taken over and second adapter, and described first adapter is connected with the import A inner chamber of valve; Described second adapter is connected with the outlet B inner chamber of valve.
As a further improvement on the present invention, described first adapter is connected with the entrance point flange of valve.
As a further improvement on the present invention; Described second adapter is connected with the outlet end flange of valve.
Compared with the prior art the present invention has the following advantages:
The present invention is simple in structure, compact, reasonable; Collection is measured, the function of control flow rate the whole body, and measuring accuracy height, good stability can satisfy the accurate aerating system of sewage treatment fully to the instant required precision of regulating of air mass flow, have remarkable energy saving effect.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Embodiment during following the present invention incites somebody to action in conjunction with the accompanying drawings is further described:
As shown in Figure 1: comprise valve 1(entrance end flange 1-1 and 1-2), intelligent electric valve actuator 2, wind differential pressure transmitter 3, first are taken over 4 and second and are taken over 5.
General D41 type and D71 type butterfly valve on the LKL-1 rhombus valve that valve 1 is produced by Jie Er company, the market.SIDM type that intelligent electric valve actuator 2 is produced by your automatic control equipment Co., Ltd of last seamount and SIMQ type etc.The MB500 type transmitter that wind differential pressure transmitter 3 is produced by Nanjing Gaohua Technology Co., Ltd..Intelligent electric valve actuator 2 is installed, wind differential pressure transmitter 3 and 1 in parallel linking to each other of valve on the described valve 1; Described wind differential pressure transmitter 3 positive and negative crimping mouths connect first respectively to be taken over 4 and second and takes over 5, and described first adapter 4 is connected with the import A inner chamber of valve 1; Described second takes over 5 is connected with the outlet B inner chamber of valve 1.
Described wind differential pressure transmitter 3 also can be connected any position (Fig. 1 is connected on the entrance end flange 1-1 and 1-2 of valve 1) of valve 1 entrance end, also can be connected on the pipeline of the close valve that is connected with valve 1.
In the accurate aerating system of sewage treatment, the aeration rate in each stage (being the pressure air flow) is different, the adjusting of air mass flow is realized by executive component that by the intelligent automatic control system the present invention is exactly the executive component that is used for accurately measuring and controlling air mass flow.When technological requirement changes flow, wind differential pressure transmitter 3 is given intelligent control system with instant detected signal feed back, intelligent control system can judge automatically whether instant flow meets technological requirement, and command adapted thereto sent to intelligent electric valve actuator 2, it is to realize to the keying of valve or to the control of valve opening by the electrical signal that changes input.Described intelligent electric valve actuator 2 drives valves 1 action, until the requirement of the aperture compliance with system instruction of valve, thereby guarantees the instant flow of technological requirement.
The present invention has obvious energy-saving effect through repeatedly experiment showed, its precision height, good stability.
