Abstract
The utility model relates to a multifunction high-pressure water filling valve which integrates the functions of the stop valve, the check valve, and the flow regulating valve. The utility model comprises a valve body, an opening seal structure in the valve body, a valve core, a valve rod which is connected with the valve core, and the elevating mechanism of the valve rod. The utility model has the improvement point that the valve core adopts a rigid ball-table seal structure to improve the erosion proof performance of the multifunction high-pressure water filling valve, the bottom end of the ball table seal structure is fixedly connected with a concave rigid throttle head in the curved surface shape; the flow regulation has the linear characteristic, and the regulation does not have dead point; the valve rod and the valve core adopt the axial sliding connection; the utility model has the check function when the sudden failures of pump stop are met.
Description
The utility model is a kind of high pressure water injection valve, is applicable to the high oil field water injection system.
At present, at home in the high pressure water injection system in each oil field, according to the requirement by, throttling, non-return of system to flowing medium, adopt common gate valve respectively or by, throttle valve and safety check, these valve function are single, mutually can not be compatible, make valve mechanism complexity, the complex operation of system, in addition these valves be not for the high pressure water injection system custom-designed, the material that spool and valve seat adopted does not possess good erosive wear resistance, makes that their working life in this system is shorter.
The purpose of this utility model is the present situation at prior art, and it is the special valve of the high pressure water injection system of one that a kind of function of melting stop valve, throttle valve, safety check is provided.
Solution of the present utility model is as follows: this sealing configuration that comprises in valve body, the valve body mouthful, the spool that matches with valve seat in the valve body, and the valve rod that connects mutually of spool and the elevator mechanism of valve rod, described spool adopts a rigidity billiard table sealing configuration, and at the curved rigid surfaces shape strangling head of the affixed protrusion in the bottom of billiard table structure, the connection of described valve rod and spool is the connection that endwisely slips.
By said structure as can be seen, spool adopts the rigid ball face seal, from saying that in shape it can make the high-voltage high-speed medium waltz through, lower the power erosion of medium, adopt erosion resistant rigid material to make from the material spool, thereby improved the sealability and the working life of valve effectively, constantly changed the discharge value of valve when the spool bottom is set up a strangling head and can be made spool with the valve rod lifting, reached the purpose of regulating valve flow.Because strangling head adopts smooth curved surface shape structure, makes the valve regulated process not have the dead point.Can finish check function for the connection that endwisely slips between valve rod and the spool; promptly when valve is worked under opening state; as when running into termination of pumping or valve inlet end piping and breaking down; then spool is taken a seat rapidly under the effect of gravity or flowing medium back pressure automatically; throttle down; cut off the refluence medium,, stablize the pressure of water injection well in order to protection water pump and miscellaneous equipment.
Describe in detail with reference to the accompanying drawings below.
Fig. 1, structural drawing of the present utility model.
Fig. 2, the valve throttle view.
Fig. 3, valve non-return view.
Referring to Fig. 1,1 is valve body, the sealing configuration 9 of spool adopts a billiard table shape, the sealing surface that makes spool and valve seat is a sphere, guarantee spool correct reliability of returning seat under the effect of deadweight and back pressure, the sealing surface weld deposit cemented carbide of spool, in order to improve its erosive wear resistance, billiard table structure bottom connects firmly a curved surface shape strangling head 10, the curved surface shape of strangling head is connect by the hemisphere face sports association of the cone on top and lower end and constitutes, connect firmly a valve stem casing 3 in billiard table structure upper end, be Spielpassung between valve rod 4 and the valve stem casing, valve rod can be slided up and down in valve stem casing, on valve stem casing, connect firmly a recoil ring 2, this recoil ring has increased the surface of contact of spool and flowing medium, and spool is stably arrheaed on the position of being regulated under the impact of high-pressure medium.In the course of the work, spool under the promotion of pressure medium along with the lifting of valve rod same moved further, thereby the size that regulating valve is opened, the strangling head shape has linear adjustment characteristic, and regulates no dead point, the valve throttle adjustment state is referring to Fig. 2; Termination of pumping or valve inlet end piping break down when running into, when medium flows backwards, then spool is taken a seat rapidly under the effect of gravity and flowing medium back pressure automatically, throttle down, valve non-return state is referring to Fig. 3.
Again referring to Fig. 1, the mode that metallic seal and rubber elasticity crush seal combine is adopted in the sealing of mouth in the valve body, in valve body, be provided with a sealing material Stuffing box 5 on the mouth, teflon " V " V-shaped ring 8 is housed in Stuffing box, gland 13 sealing Stuffing boxes are suitable for reading, cover Stuffing box with loam cake 14 again, screw thread tightens.On screw rod 4, be provided with a valve body back seal structure 30, do not make valve rod deviate to hurt sb.'s feelings first, second when valve wide open, can protect filler not to be subjected to the medium erosion.Valve body is suitable for reading to connect firmly a support 27 by flange arrangement, valve rod through the carriage center position, the support flange plate of going to the bottom is pushed down Stuffing box, and connects firmly with nut 12 and valve body flange plate suitable for reading by screw 11 and to be in the same place, and the surface of contact of Stuffing box and valve body is provided with O-ring seals 6,7.Fix a Stem Mut 26 on support top, there is a stem guiding key 15 that is fixed on the support lower end of Stem Mut, to prevent that valve rod from rotating in a circumferential direction, between Stem Mut and feather key surface of contact, be lined with antifriction sheet 16, a thrust bearing 18 has been installed on Stem Mut, on support, be provided with a screw of handle 17, after the valve rod adjustable height is set up, with screw of handle lock valve stem nut, prevent the valve rod axial float, make not reason medium impulsion and change valve opening of valve, influence flow, upper end at Stem Mut connects firmly impact block 22 by flat key 23, and the corresponding bump wheel hub that is provided with in the center portion of handwheel 21 is when rotation hand wheel, bump wheel hub and impact block clash into mutually, the rotation of drive Stem Mut moves up and down valve rod, and this structure can make the opening and closing of valve comparatively laborsaving, at the valve rod tail end valve rod cover 25 is installed, a window is arranged on the cover, can see the height of valve rod lifting, thus the aperture of observing valve intuitively.Fig. 1 is the cut-off state of valve, and 19 among this figure is thrust bearing glands, the 20th, and screw, the 24th, back-up ring, the 28th, nameplate rivet, the 29th, nameplate.
