Abstract
The utility model discloses a multi-stage sealed adjustable full-drift-diameter wellhead device, which is characterized by comprising a guide pipe connection hook, an upper end socket and an air inlet and exhaust connector, wherein the lower part of the guide pipe connection hoop is in threaded connection with an air pollution index (API) guide pipe, and the upper part of the guide pipe connection hoop is in direct threaded connection with the upper end socket; the upper end socket is connected with a frustum at the lower end of the air inlet and exhaust connector in a taper thread sealing manner; four O-shaped sealing gaskets are arranged at the lower end of the upper end socket; a sealing inclined surface is formed at the upper end of the upper end socket; two O-shaped sealing gaskets are arranged on the sealing inclined surface 2; the upper end of the upper end socket is a convex circular ring; a waterproof rubber gasket is arranged on the inner side of the circular ring; and an air inlet and exhaust port and a dirt discharging port are formed on the air inlet and exhaust connector. The weight of the multi-stage sealed adjustable full-drift-diameter wellhead device is less than that of a flange-type wellhead device, so that 2/3 steel materials are saved; the multi-stage sealed adjustable full-drift-diameter wellhead device has a simple structure, and is easy to process and low in processing cost; due to the light weight, the transportation cost can be reduced by 2/3; the multi-stage sealed adjustable full-drift-diameter wellhead device is easy to mount on the site; directions of the air inlet and exhaust port and the dirt discharging port can be adjusted randomly; and the multi-stage sealed adjustable full-drift-diameter wellhead device is sealed reliably and safely.
Description
Technical field
The utility model relates to the gas storage well wellhead assembly.
Background technique
National technical supervision general bureau must adopt the all-pass footpath to gas storage well code requirement gas storage well wellhead assembly in 2009; Present most of gas storage well is built unit and is all adopted the flange-type wellhead assembly to realize the all-pass footpath; Flange-type wellhead assembly volume is big; Weight is 5-6 times of old-fashioned gas storage well wellhead assembly, and cost is high, difficult installation.
Summary of the invention
In order to overcome above-mentioned shortcoming, the utility model provides a kind of multi-stage sealed can regulate all-pass footpath wellhead assembly.This apparatus structure is simple, in light weight, easy for installation, sealing is reliable and secure.
Multi-stage sealed can regulate all-pass footpath wellhead assembly, its characteristic comprises: conduit box cupling 1, upper cover 2 and intake and exhaust joint 4, conduit box cupling 1 bottom is connected through screw thread 31 with API conduit 3, and conduit box cupling 1 top is connected through straight thread 11 with upper cover 2; Being connected between the frustum of upper cover 2 and intake and exhaust joint 4 lower ends adopts tapered thread 41 to be tightly connected; Upper cover 2 lower ends are provided with 4 roads " O " RunddichtringO 21; There is a sealing inclined-plane 22 outer ring, upper cover 2 upper end, on sealing inclined-plane 22,2 roads " O " RunddichtringO 23 is arranged, and the upper end portion of upper cover 2 is annulus 24 of a protrusion; The interior survey of annulus 24 has waterproof apron 25, and intake and exhaust joint 4 is provided with porting 42 and sewage draining exit 43.
The utility model has the advantages that:
1, the weight of the utility model is light than the flange-type wellhead assembly, practices thrift steel 2/3.
2, simple in structure, easy processing, processing charges is low.
3,, can make freight reduce by 2/3 owing in light weight.
4, the on-the-spot installation simply.
5, the direction of porting 42 and sewage draining exit 43 can be regulated arbitrarily.Being connected between the frustum of upper cover 2 and intake and exhaust joint 4 lower ends adopts tapered thread 41 to be tightly connected, because the tapered thread packing torque is an interval value, rotation intake and exhaust joint 4 can be adjusted porting 42 and the direction of sewage draining exit 43 on the intake and exhaust joint 4.
6, sealing is reliable and secure.Upper cover 2 lower ends are provided with 4 roads " O " RunddichtringO 21 and carry out sealing; There is a sealing inclined-plane 22 upper cover 2 upper ends, on sealing inclined-plane 22, have 2 roads " O " RunddichtringO 23 to carry out hard sealing.
Therefore 7, conduit box cupling 1 top is connected through straight thread 11 with upper cover 2, and 11 interconnect functions of straight thread do not seal, and can dismantle repeatedly easily, takes rear tube 3 apart and is all-pass and directly is convenient to detect and safeguard gas storage well.
8, the upper end portion of upper cover 2 is annulus 24 of a protrusion, and there is waterproof apron 25 inboard of annulus 24, and gas storage well does not advance rainwater water, increases the working life of gas storage well.
