Description
Technical field
The utility model belongs to water-treatment technology field, relates to a kind of non-negative pressure stabilized adjuster.
background technology
At present, water conservancy city planting ductwork anti-pressure ability in city is poor, while taking over to the large-scale negative pressure equipment of enterprise from municipal water supply pipe network, can cause very large negative pressure to municipal water supply pipe, cause municipal water supply pipe or city planting ductwork to break, so between negative pressure equipment and municipal water supply pipe, lack a kind of city planting ductwork and negative pressure equipment of connecting, make the whole service process of equipment can not cause negative pressure to pipe network, simultaneously by regulating water supply flow to make the more reliable stable current regulator of equipment operation, can support the use with the intelligent negative pressure equipment of my company, reach the object that reduces municipal water supply pipe negative pressure.
Summary of the invention
For above-mentioned situation; the utility model provides a kind of non-negative pressure stabilized adjuster; non-negative pressure stabilized adjuster connects city planting ductwork and negative pressure equipment; municipal ductwork pressure signal is fed back to accurately control axis by pressure detecting part; control axis is made the operating instruction of adjust flux according to feedback data, protection city planting ductwork can not produce negative pressure.In the time that water inlet is sufficient, it increases pipe network water supply amount protection negative pressure equipment water supply volume; in the time that water inlet is not enough; reduce pipe network water supply amount and protect municipal ductwork pressure; also set up emergency protecting equipment; in the time that control axis fault is out of control; protective device can disconnect fast without the connecting of negative pressure and pipe network, and pipe network is played to triple protection function.
To achieve these goals, the technical solution of the utility model is as follows:
Non-negative pressure stabilized adjuster, comprise adjuster casing, pressure sensor, flow regulator, control axis, display, it is characterized in that, described adjuster tank ends is respectively arrival end and the port of export, arrival end is connected with municipal water supply pipe and negative pressure equipment respectively by flange with the port of export, in adjuster casing, be provided with reserved pressure chamber, pressure is provided with pressure sensor in chamber, pressure sensor is connected by analog signal transmission with control axis, described flow regulator comprises that stainless steel is to folder butterfly valve and YE, described YE is located in adjuster casing, folder butterfly valve is laterally placed in to casing middle part, YE with to folder butterfly valve be connected by connecting rod, YE is connected by electric signal transmission with control axis, described control axis is connected with display.
Described control axis comprises data processing unit and fault self-checking equipment.
Described non-negative pressure stabilized adjuster also comprises protective device; protective device comprises negative pressure dividing plate and the second YE; negative pressure dividing plate is laterally placed in top, pressure chamber, and negative pressure dividing plate is connected by connecting rod with the second YE, and described the second YE is connected with control axis.In the time that the fault self-checking module of control axis detects fault; control axis will be controlled the second YE and open; current in negative pressure dividing plate blocking-up adjuster casing, disconnect being connected of negative pressure equipment and city planting ductwork fast, and city planting ductwork is played to absolute defencive function.
The utility model has the advantages that: non-negative pressure stabilized adjuster connects city planting ductwork and negative pressure equipment; municipal ductwork pressure signal is fed back to accurately control axis by pressure detecting part; control axis is made the operating instruction of adjust flux according to feedback data, protection city planting ductwork can not produce negative pressure.In the time that water inlet is sufficient, it increases pipe network water supply amount protection negative pressure equipment water supply volume; in the time that water inlet is not enough; reduce pipe network water supply amount and protect municipal ductwork pressure; also set up emergency protecting equipment; in the time that control axis fault is out of control; protective device can disconnect fast without the connecting of negative pressure and pipe network, and pipe network is played to triple protection function.
