Operating efficiency problem.
To achieve the above object, the utility model provides following technical scheme：A kind of dismountable check-valves, including first
Valve body, the side of first valve body is connected with feed tube, and the inside of the first valve body is fixed with screen pack, the screen pack with
Check valve spool is connected by adjustable spring, and seal gasket, first valve are provided between the check valve spool and feed tube
Sealing ring is provided between body and the second valve body, the side of second valve body is connected with drain pipe.
Preferably, the surface of the check valve spool is provided with epoxy anticorrosive coating.
Preferably, the surface of first valve body is provided with heavy list rivet clip, the upper peace of the heavy list rivet clip
Equipped with fixed plate.
Preferably, the fixed plate is provided with four altogether, and four fixed plates are separately mounted on the outer wall of the first valve body, and four
Connected by fastening bolt between individual described fixed plate.
Preferably, the adjustable spring passes through to be welded to connect with check valve spool.
Compared with prior art, the beneficial effects of the utility model are：The utility model is scientific and reasonable for structure, easy to use
Efficiently；Screen pack is provided with by the inside of the first valve body, filtration treatment can be carried out to the liquid being input into, it is to avoid impurity directly from
Drain pipe flows out, it is ensured that the purity of liquid；By adjusting fastening bolt, the first valve body and the second valve body can be separated,
The convenient impurity to valve inner is cleared up, it is to avoid valve inner produces clogging, improves the practicality of check-valves；It is logical
The surface for crossing check valve spool is provided with epoxy anticorrosive coating, the erosion of check valve spool not liquid body can be protected, with anti-corrosion
Effect of erosion, so as to extend the service life of check valve spool.
