Description
Technical field
The utility model belongs to ball-and-seat technical field, and in particular to a kind of ball-and-seat for pump discharge.
Background technology
The effect of ball-and-seat is blocked in the uniguide implemented under high temperature, condition of high voltage.In the injection pipe network of ground, Dan Liu
The performance quality of valve directly affects the success or failure entirely constructed.Mechanical performance and the job stability for improving ball-and-seat are particularly heavy
It wants.But existing ball-and-seat poor sealing, performance are not sufficiently stable.
Invention content
The purpose of this utility model is that providing a kind of single stream for pump discharge for problems of the prior art
Valve.
The technical solution of the utility model is：
A kind of ball-and-seat for pump discharge, including main body, main body are three-port structure, and main body one end is connected with sealing and connects
Head, the corresponding other end are inlet, and the central through hole of the main body is stepped, the central through hole center position of main body
It is provided with sleeve, valve ball is set in sleeve, valve ball seat is on ball seat, and ball seat is sitting on the interior shoulder of the central through hole of main body, ball
Seat closely forms sealing structure with sleeve simultaneously, through-hole is offered on the barrel of the sleeve, the inner cylinder of sleeve is the conical surface, interior
For the small one end of diameter towards valve ball, the sleeve is closely provided with U-rail slot on one end end of seal nipple.
Specifically, the seal nipple is connect by screw thread with main body, and screw is set and reinforces fixing.
Specifically, being sealed by sealing ring between the ball seat and main body.
Specifically, there are two the U-rail slots, and be oppositely arranged.
Specifically, the through-hole on the barrel of the sleeve is 6-10.
The utility model has the beneficial effects that：The ball-and-seat is connected to water-injection station pump discharge position, seal nipple and master
Body threaded connection can dismantle cleaning inner cavity, replace accessory at any time；The double-U-shaped track groove of sleeve ends setting is easy to disassemble, and inside is set
Small Taper inner cavity is set, valve ball is facilitated to return sealing station.The utility model is simple and reasonable, and sealing effect is good, and performance is stable, applies
Work is applied to power height and has stronger applicability.Construction success rate can be greatly improved using the ball-and-seat, effectively reduce production
Cost.
Description of the drawings
Fig. 1 is the apparatus structure schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of sleeve.
1 seal nipple, 2 main bodys, 3 sleeves, 4 ball seats, 5U types track groove, 6 valve balls, 7 sealing rings,
8 leakage fluid drams, 9 screws, 10 sealing rings, 11 inlets, 12 through-holes.
Specific implementation mode
It is a kind of structural schematic diagram of ball-and-seat for pump discharge, including main body 2 as shown in Figure 1, main body 2 is threeway knot
Structure, 2 one end of main body are connected with seal nipple 1, and the seal nipple 1 is connect by screw thread with main body 2, and screw 9 is arranged and adds
Strong fixed, 2 other end of main body is inlet opening 11, and the central through hole of the main body 2 is stepped, in the central through hole of main body 2
It is provided with sleeve 3 at heart position, valve ball 6 is set in sleeve 3, and for valve ball 6 on ball seat 4, the center that ball seat 4 is sitting in main body 2 is logical
It on the interior shoulder in hole, is sealed by sealing ring 10 between ball seat 4 and main body 2, ball seat 4 closely forms sealing knot with sleeve 3 simultaneously
Structure offers through-hole on the barrel of the sleeve 3, and the through-hole on the barrel of the sleeve 3 is 6-10.Sleeve 3 it is interior
Cylinder is the conical surface, and for the small one end of internal diameter towards valve ball 6, the seal nipple 1 is closely provided with U-rail on one end of sleeve 3
Slot 5, it is easy to disassemble, it is illustrated in figure 2 the structural schematic diagram of U-rail slot 5.There are two U-rail slots 5, and is oppositely arranged.
Using ball-and-seat described in the utility model, when normal water filling, flow is entered by the inlet pumped multi-functional prevents back
It flows in device, flow enters main body 2 to push valve ball 6 from inlet 11, so that the displacement of valve ball 6 is formed flow channels, water flows through
Through-hole outflow on sleeve 3 enters pipeline by leakage fluid dram 8；When water injection well stops note for some reason, valve ball 6 is returned in dead weight and waterflood-transmission line
Pressure effect is lower to return to sealing station along 3 conical surface of sleeve, closes water stream channel channel, prevents the water in pipeline from returning in pump, ensure
Stratum not will produce fluctuation and cause to shake out, stop note after can turn on pump water filling again at any time, avoid water injection well stop for some reason note after generate warp
Ji loss.
Finally it should be noted that:Above example is only to illustrate the technical solution of the utility model rather than limits it
System；Although the utility model is described in detail with reference to preferred embodiment, those of ordinary skill in the art should
Understand：It can still modify to specific embodiment of the present utility model or some technical characteristics are equally replaced
It changes；Without departing from the spirit of technical solutions of the utility model, should all cover in the claimed technical solution of the utility model
In range.
