Abstract
The utility model relates to an integral multiple-valve type Christmas tree wellhead device, which is used for solving the problems of leakage and higher occupied space height caused by the connection of multiple parts of valves, crosses and the like of an oil wellhead. The device is characterized in that the casings of a main valve, the cross and a paraffin removal valve are designed into a whole and are integrally connected; the main valve, the cross and the paraffin removal valve are combined into a cross. The main body of a casing head is in blind studding with the main body of an oil pipe head, and a single-head bolt nut penetrates through a flange arranged at the upper end of the main body of the oil pipe head and is tightened with the main body of the casing head. The integral multiple-valve type Christmas tree wellhead device has the advantages of small volume, small height, light weight, convenient installation, maintenance and operation, low cost and the like.
Description
Technical field
The utility model relates to a kind of multi-valve type production tree well head device, and it connects the seepage and the highly bigger problem of bringing that takes up space with solving multi-parts such as well mouth of oil well valve body, four-way.Belong to oil equipment mechanical manufacturing field.
Background technology
The production tree that is used for the oil field shaft mouth device at present adopts split-type structural also tightly to assemble by flange, stud, double nut by main valve, four-way and paraffin valve.Thereby this device volume space big, that occupy is big; Weight materials many, that consume are many, connector is also many.And cause the possibility increase of oil liquid leakage along with increasing of fitting surface.In addition the tubing head four-way of this device lower end adopt equally up and down flange, stud, double nut respectively with casing head, tubing head on flange fastening.So caused the volume of this device huger, especially the volume exclusion on the height is very big.Therefore design that a kind of volume is little, highly little, in light weight, fitting surface is few, satisfy many valves disjunctor production tree well head device of function needs again, will be subjected to extensive welcome.
Summary of the invention
In volume, height space and the technical problem that easily exists aspect the leakage, the utility model proposes a kind of one multi-valve type production tree well head device at present multi-valve type production tree.
To achieve these goals, the utility model takes following technical scheme to implement: it is made of multi-functional integrated valve, casing head body, tubing head body, single ended bolt mother etc.It is characterized in that a plurality of parts enclosure designs of described main valve, four-way and paraffin valve are as a whole; Adopt monolithic to connect between a plurality of workpiece shells of described main valve, four-way and paraffin valve; The a plurality of unit constructions of described main valve, four-way and paraffin valve become four-way.Adopt the blind hole studding between described casing head body and the tubing head body, single ended bolt mother passes flange and the casing head body and tight that tubing head body upper end is provided with.。
The utlity model has advantages such as volume is little, highly little, weight is little, installation and maintenance are easy to operate, with low cost.
Description of drawings
Accompanying drawing 1 is a main TV structure schematic diagram of the present utility model;
In accompanying drawing 1,2,3: 1 casing head body, 2 tubing head bodies, 3 multi-functional integrated valves, 4 single ended bolt mothers.
The specific embodiment
Shown in accompanying drawing 1,2,3, it is bad to adopt Forging Technology to produce the hair of multi-functional integrated valve 3, be made into multi-functional integrated valve 3 with many valve bodies and four-way allomeric function by various processing technologys, annexation between multi-functional integrated valve 3 inner chambers is connected the back relation with a plurality of workpiece of main valve, four-way and paraffin valve in the former production tree well head device identical, promptly is equivalent to the allomeric function by the valve body in the former production tree, four-way.Thereby multi-functional integrated valve 3 both can regard valve as, also can be considered as four-way.Simultaneously owing to be integral design, thereby do not have link, more do not have the seepage phenomenon to produce.Space length between each parts diminishes and causes the production tree whole height to descend.The lower end of tubing head body 2 is designed to studding tooth inner bolt hole, adopts single ended bolt mother 4 to pass flange and the casing head body 2 that tubing head body 1 upper end is provided with and connects.Because when casing head body 1 has reduced the required space of flange and double nut and stressed joint and cap required space, thereby reduced the height of casing head body 2 effectively.
Claims (2)
1. one multi-valve type production tree well head device, it is made of multi-functional integrated valve, casing head body, tubing head body, single ended bolt mother etc., it is characterized in that a plurality of parts enclosure designs of described main valve, four-way and paraffin valve are as a whole; Adopt monolithic to connect between a plurality of workpiece shells of described main valve, four-way and paraffin valve; The a plurality of unit constructions of described main valve, four-way and paraffin valve become four-way.
2. one multi-valve type production tree well head device according to claim 1 is characterized in that adopting between described casing head body and the tubing head body blind hole studding, and single ended bolt mother passes flange and the casing head body and tight that tubing head body upper end is provided with.
