Abstract
A nitrogen filter comprises an upper filter housing and a lower filter housing and is characterized in that the upper filter housing is connected with the lower filter housing in a fastening manner by a sealing ring; a gas inlet and a gas outlet are formed at the upper end of the upper filter housing; a partition for isolating the gas inlet from the gas outlet is further arranged in the upper filter housing; the gas inlet is connected with an air filter; filter elements are fixed on the partition; and a ball valve is arranged at the bottom end of the lower filter housing and connected with an automatic drainer. Compared with the traditional technology, the filter is simple in structure, good in use effect and high in practicability, and filters impurities out of a nitrogen flow better.
Description
Technical field
The utility model relates to a kind of filter, is specially a kind of nitrogen filtering device.
Background technology
Nitrogen plays a part very important in process of production; the nitrogen filtering device is indispensable a kind of device on the pumped (conveying) medium pipeline; usually be arranged on the entrance point of pressure-reducing valve, relief valve, Valve for keeping constant water level or miscellaneous equipment; be used for eliminating the impurity in medium, with the normal use of protection valve and equipment.Although be provided with filter core in the nitrogen filtering device, can not guarantee that the gas of exporting from the nitrogen filtering device is very pure, make from filter outlet gas out impure, affect the quality of production.
