Abstract
The utility model relates to a combined valve capable of measuring and controlling flow precisely, comprising a valve and an intelligent electrically operated valve executing mechanism which is arranged on the valve. The combined valve is characterized in that a wind differential pressure transmitter is connected with the valve in parallel; positive and negative pressure connectors of the wind differential pressure transmitter are respectively connected with a first connection pipe and a second connection pipe; the first connection pipe is connected with an inner cavity of an inlet of the valve; and the second connection pipe is connected with an inner cavity of an outlet of the valve. The combined valve is simple, compact and reasonable in structure, integrates the functions of measuring and controlling flow, has high measuring precision and good stability, can completely meet the requirement of a precise aeration system for sewage treatment on the precision of immediate adjustment on air flow, and has an obvious energy-saving effect.
Description
Technical field
The utility model relates to a kind of flow and accurately measures the control combination valve, specifically is used for having on the accurate aerating system of sewage treatment the multi-functional executive component of accurate measurement and control air flow, belongs 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 on the export pipeline near 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 demands of different 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 through 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 to flow control, do not reach desirable energy-conservation requirement.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, thereby provides a kind of flow accurately to measure the control combination valve, and it integrates the function of measurement, control flow rate, and precision is high, good stability.
According to the technological scheme that the utility model provides, 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 said valve, and characteristic is: the wind differential pressure transmitter links to each other with the valve parallel connection; The positive and negative crimping mouth of said wind differential pressure transmitter connects first respectively to be taken over and second adapter, and said first adapter is connected with the import A inner chamber of valve; Said second adapter is connected with the outlet B inner chamber of valve.
As further improvement of the present invention, said first adapter is connected with the entrance point flange of valve.
As further improvement of the present invention; Said second adapter is connected with the outlet end flange of valve.
Compared with present technology the utility model has the following advantages:
The utility model is simple in structure, compact, reasonable; Collection is measured, the function of control flow rate the whole body, and measuring accuracy is high, good stability, can satisfy the accurate aerating system of sewage treatment fully to the instant required precision of regulating of air mass flow, has remarkable energy saving effect.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Following the utility model will combine the embodiment in the accompanying drawing to further describe:
As shown in Figure 1: as to comprise valve 1 (entrance end flange 1-1 and 1-2), intelligent electric valve actuator 2, wind differential pressure transmitter 3, first adapter, 4 and second adapter 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 on the said valve 1, and wind differential pressure transmitter 3 links to each other with valve 1 parallel connection; Said 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 said first adapter 4 is connected with the import A inner chamber of valve 1; Said second takes over 5 is connected with the outlet B inner chamber of valve 1.
Said 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 with pipeline that valve 1 is connected near valve on.
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 through executive component that by the intelligent automatic control system the utility model is exactly the executive component that is used for accurately measurement and control air 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 be judged whether according with process requirements of instant flow automatically; 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.Said 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 utility model has obvious energy-saving effect through experiment showed, that repeatedly its precision is high, good stability.
