Description

Universal valve for PVC (polyvinyl chloride) pipeline

Technical Field

The utility model relates to a valve, more exactly, be a general valve of PVC pipeline.

Background

The development of the regulating valve has been in the history of eighty years from the beginning of the 20 th century to the present, and ten major types of regulating valve products, self-operated valves, positioners and the like are successively generated and used for regulating technological parameters such as medium flow, pressure, temperature, liquid level and the like in the field of industrial automation process control. The opening of the valve is automatically adjusted according to a control signal in an automatic system, so that the adjustment of medium flow, pressure, temperature and liquid level is realized, and the adjusting valve in the 90 s is mainly used for the aspects of reliability and the attack, improvement and improvement of special difficult products. By the end of the 90 s, a tenth design product, a full-function ultra-light valve, was introduced by the waring company. It features its breakthrough in reliability, function and weight. A breakthrough in function, namely a unique product with full function, so that a product can replace various products with incomplete functions, thereby simplifying the selection, the use and the variety; the weight of the valve is 70-80% lighter than that of a single-seat valve, a double-seat valve and a sleeve valve which are dominant products, and the valve is 40-50% lighter than that of a small valve; the breakthrough of reliability-the problems of various unreliability factors such as the reliability of sealing, the reliability of positioning and the reliability of action of the traditional regulating valve are solved. The product is produced, so that the technology and application level of the regulating valve in China reach the advanced level in the end of the nineties; it is a major breakthrough in regulating valves; especially, the electronic type full-function ultra-light valve is bound to become the mainstream of the adjusting valve in the next century.

The existing universal valve for the PVC pipeline is simple in structure and single in function, is lack of control precision, is slow in opening and closing speed, cannot determine flow rapidly, needs to be opened and closed manually, is completely empirical in flow control, and cannot display accurate flow.
