Abstract
The invention creates a production well mouth stop valve apparatus comprising a valve body, a valve core, an inlet end, an outlet end, a sealing pad, a cover port, a pressure-releasing screw and an O-shaped rubber sealing ring. The valve core is disposed in the valve body; a burying structure is individually arranged on the upper and lower parts of the valve core to buffer impact pressure; the tail end of the valve core is provided with an inlet end; one side of the lower end of the valve core close to the inlet end is provided with an outlet end; the inlet end is perpendicular to the outlet end; a pressure-releasing screw is arranged beside the outlet end to play a buffering action; the valve core is provided with a sealing pad to guarantee sealing property and safety of the stop valve; the cover port is mounted on the valve body; the cover port can be opened by a matchable tool to guarantee safety of the opening of the stop valve; flow speed can be well controlled by the design of the vertical flow path; a special end port ensures safety; and the production well mouth stop valve apparatus has low manufacturing cost, great pressure resistant performance and can be simply maintained.
Description
Technical field
The invention belongs to petroleum engineering technical field, especially relates to a kind of oil production wellhead stop valve.
Background technology
Stop valve on present oil development production tree generally adopts rising stem (RS.) hand wheel type structure, by the connection such as flange, clip, this kind of connected mode, anyone can open and close, very easily cause leakage of oil, steal the generation of oily phenomenon even seriously to the accident such as make oil well out of hand, finally cause serious economic loss and pollution, therefore urgently new on oil exploitation market sealing is good, the generation of the stop valve that security performance is high.
Summary of the invention
In view of this, the invention is intended to propose a kind of oil production wellhead stop valve device, to solve oil production wellhead stop valve poor safety performance, and the problem of sealing difference.
For achieving the above object, the technical scheme of the invention is achieved in that oil production wellhead stop valve device, comprise valve body, spool, entrance point, the port of export, sealing mat, lid mouth, release screw, O type rubber seal, described valve inner is provided with spool, described spool inner face is provided with plush copper structure, described valve body is provided with entrance point be directly connected with spool, described spool low side is provided with the port of export near entrance point side, the described port of export is other is provided with release screw, described release screw is directly connected with spool, described spool is provided with sealing mat, described valve body is provided with lid mouth, described sealing mat is positioned at spool and Gai Kou contact position.
Further, described entrance point is mutually vertical with port of export opening direction, and described entrance point and port of export internal structure are Straight.
Further, described lid mouth is configured with special opener.
Further, described lid mouth and spool coupling part are provided with O type rubber seal.
Further, described port of export bore is slightly larger than entrance point bore.
Further, described release screw is T-shaped threaded screws.
Relative to prior art, the oil production wellhead stop valve device described in the invention has following advantage:
(1) spool of the present invention is provided with up and down and immerses oneself in structure, can shock absorbing pressure, described entrance point is mutually vertical with port of export opening direction, and the described port of export is other is provided with release screw, and release screw plays mitigation, described spool is provided with sealing mat, ensure that sealing and the safety of stop valve, the setting of particular port ensure that safety, and cheap for manufacturing cost, compression resistance performance is good, easy to maintenance.
(2) arranging of vertical stratification of the present invention can realize oily velocity of liquid assets as soon as possible, reduce and be detained in valve body, further, described valve body is provided with lid mouth, described lid mouth is configured with special opener, and this lid mouth needs with the TO matched, ensure that the safety that stop valve is opened, further, described lid mouth and spool coupling part are provided with O type rubber seal, ensure that safety and the application life of stop valve.
Accompanying drawing explanation
The accompanying drawing of the part of formation the invention is used to provide the further understanding to the invention, and the schematic description and description of the invention, for explaining the invention, does not form the improper restriction to the invention.In the accompanying drawings:
Fig. 1 is the oil production wellhead stop valve device described in the invention embodiment.
Description of reference numerals:
1-valve body, 2-spool, 3-entrance point, the 4-port of export, 5-sealing mat, 6-release screw, 7-lid mouth, 8-O type rubber seal.
Detailed description of the invention
It should be noted that, when not conflicting, the embodiment in the invention and the feature in embodiment can combine mutually.
Below with reference to the accompanying drawings and describe the invention in detail in conjunction with the embodiments.
Oil production wellhead stop valve device, comprise valve body 1, spool 2, entrance point 3, the port of export 4, sealing mat 5, lid mouth 7, release screw 6, O type rubber seal 8, valve body 1 inside is provided with spool 2, spool 2 inner face is provided with plush copper structure, valve body 1 is provided with entrance point 3 to be directly connected with spool 2, spool 2 low side is provided with the port of export 4 near entrance point 3 side, the port of export 4 is other is provided with release screw 7, release screw 6 is directly connected with spool 2, spool 2 is provided with sealing mat 5, valve body 1 is provided with lid mouth 7, and sealing mat 5 is positioned at spool 2 and lid mouth 7 contact position.
Entrance point 3 and the port of export 4 are in vertical configuration, and entrance point 3 and the port of export 4 internal structure are Straight.
Lid mouth 7 is configured with special opener, and this stop valve cannot not opened by the opener supporting with lid mouth, which ensure that and adopts device from the safety source, avoid the generation of stolen phenomenon.
Lid mouth 7 and spool 2 coupling part are provided with O type rubber seal 8, oil recovery stop valve in the past lacks rubber seal, often there is oil leakage phenomenon, and there is no the stop valve of rubber seal, because the corrosion of grease etc., the stop valve life-span is shorter, the setting of this oil production wellhead stop valve device rubber seal, can change in time or keep in repair, ensure that the life-span of stop valve.
The port of export 5 bore is slightly larger than entrance point 4 bore, and valve body internal memory oil pressure is alleviated in this design.
Release screw 7 is T-shaped threaded screws, and the T-shaped oil that arranges is walked toward both sides, reduces the impact force to screw.
The foregoing is only the preferred embodiment of the invention; not in order to limit the invention; within all spirit in the invention and principle, any amendment done, equivalent replacement, improvement etc., within the protection domain that all should be included in the invention.
