Novel oilfield water injection well valve.
The purpose of this utility model is to be achieved through the following technical solutions：
A kind of novel oilfield water injection well valve, including one-way non-return valve, filling pipe, water inlet pipe, connecting stud, sealing
Cushion rubber, water-swellable waterstop, have check valve sealing flange outside the one-way non-return valve, in check valve sealing flange
Portion is uniformly distributed No.1 through-hole, has No.1 aprons slot inside check valve sealing flange, inside has No.1 positioning ring groove, single
There are No. two positioning ring grooves inside to valve sealing flange, there are No. three positioning ring grooves inside check valve sealing flange, unidirectionally
There is cone boss outside valve sealing flange, there is apopore inside one-way non-return valve, described filling pipe one end has note
Water pipe sealing flange is uniformly distributed No. two through-holes inside water injection pipe sealing flange, has inside water injection pipe sealing flange
No. two aprons slots, water injection pipe sealing flange outside have No.1 positioning ring, outside water injection pipe sealing flange there are No. two to be determined
Position ring, water injection pipe sealing flange outside have No. three positioning rings, have cone boss slot, note inside water injection pipe sealing flange
There is blasthole, water-swellable waterstop is placed in cone boss slot, and No.1 aprons slot is matched with No. two aprons slots inside waterpipe
Conjunction forms cushion rubber chamber, and sealing rubber ring merging cushion rubber is intracavitary, and No.1 positioning ring is placed in No.1 positioning ring groove, No. two positioning rings mergings
In No. two positioning ring grooves, No. three positioning rings are placed in No. three positioning ring grooves, and cone boss is placed in cone boss slot, cone boss
Bottom surface and water-swellable waterstop top surface cooperate, and apopore and blasthole cooperatively form flow cavity, and connecting stud is placed in one number service
Hole is in No. two through-holes, and tightly, one-way non-return valve is connect with filling pipe for connecting stud both ends and fixture nut.
The one-way non-return valve other end has water intake end ring flange, and the water inlet pipe end has, one-way non-return valve
With water inlet pipe by water intake end ring flange and cooperation flanged joint.
Beneficial effect：
No.1 positioning ring groove, No. two positioning ring grooves, No. three positioning ring grooves and No.1 positioning ring, No. two positioning rings, No. three it is fixed
The common cooperation of position ring, forms labyrinth seal, the leakproofness of junction can be made better, the merging of water-swellable waterstop
In cone boss slot, cone boss and cone boss slot cooperate, and water-swellable waterstop water-swellable can be with the taper of contact
Face cooperation, make at gap seal it is more compact, leakproofness is good, structurally reasonable, sealing rubber ring, water-swellable waterstop, labyrinth
The common cooperation of sealing can play multi-sealed property protection, increase the leakproofness of junction, structurally reasonable.
