Description
(1) technical field
The utility model relates to natural valve station equipment, particularly the T-shaped filter of a kind of natural gas odorization machine.
(2) background technology
In natural-gas station house equipment, usually adopt for the sake of security the natural gas odorization machine to natural gas odorization, user or staff can be perceiveed very soon when combustion gas occurs to leak.But often can contain impurity in smelly liquid (thiophane), in the odorization machine pipeline, usually filter will be installed.Common filter is duct type, as the dismounting filter core must whole filter from pipeline disassemble can, keep in repair very inconvenient.
(3) utility model content
The purpose of this utility model is for above-mentioned existing problems, provides a kind of natural gas odorization machine T-shaped filter, and its operation good filtration effect, sealing property are strong, filter core disassembly, cleaning online, easy to maintenance, can guarantee the safe operation of complete equipment.
The technical solution of the utility model:
The T-shaped filter of a kind of natural gas odorization machine, be comprised of top cover, attaching nut, body, stainless steel filter core and spring, and top cover is the stairstepping cylinder and is provided with stepped cylindrical center inner chamber, and central lumen top is spring cavity; Body is T-shaped valve body structure and is provided with air inlet and gas outlet, the cylindrical on body top is provided with external screw thread, inside is provided with the cylindrical center inner chamber, air inlet communicates by bottom with the body central lumen, gas outlet communicates by side with the body central lumen, the bottom of body is provided with two screws, and T-shaped filter utilizes two screws and panel to fix; Top cover is connected by the attaching nut with body and is provided with polytetrafluoroethylsealed sealed pad a; The stainless steel filter core is for falling cup-shaped cylindrical structure, and side and the end face of stainless steel filter core are evenly equipped with filter opening, and the stainless steel filter core is arranged in the central lumen of body, is provided with polytetrafluoroethylsealed sealed pad b between the bottom of the lower port of stainless steel filter core and body central lumen; Spring is positioned at the spring cavity of top cover central lumen, and the upper surface of spring and lower surface join and the stainless steel filter core is compressed with the end face of spring cavity and the end face of stainless steel filter core respectively.
Working procedure of the present utility model:
Natural gas odorization liquid (thiophane) enters stainless steel filter core inside by filter inlet, and after filter element filtering, smelly liquid flows out from filter core is outside, and the smelly liquid that has been filtered impurity flows into downstream line by filter outlet.When filter core generation obstruction maybe needs to clean, to turn on bonnet nut and take off valve gap, filter core just can be pulled down processing.
The scope of application of the present utility model is: the large-scale gas company of device for adding odor, Men Zhan, industrial park and the residential quarter station in city are arranged.
The utility model has the advantages that: this apparatus structure is simple, cost is low; Volume is little, safe and reliable to operation; Can dismantle online, easy to maintenance.
