Abstract
The utility model relates to a power head and faucet wash pipe seal device with a double-seal function. The novel power head wash pipe seal device comprises a packing box (1), seal spacer rings (2), seal packing (3), a lubricating oil cup (5) and an anti-loosening plug (10). The novel power head wash pipe seal device is characterized in that the seal packing is divided into three blocks through an upper seal spacer ring (2), a lubricating seal spacer ring (4), a double-function seal spacer ring (6) and a lower seal spacer ring (8), each seal spacer ring is provided with a seal groove, the cross section of the seal groove is provided with a groove body in a semi-circular shape, an O-shaped ring (7) is arranged in the groove body, and the anti-loosening plug (10) is arranged at the lower portion of the packing box. The novel power head wash pipe seal device solves the problem that power head and faucet wash pipe seal packing arranged on an existing drilling machine and a workover rig is short in service life. Meanwhile, the seal device is convenient to mount, and the seal packing is prevented from being repeatedly replaced, so that working efficiency is greatly improved.
Description
Technical field:
The utility model relates to a kind of unit head with double-sealing effect, water tap washing pipe seal arrangement.
Background technique:
In the drilling process of oil, rock gas and coal-seam gas, need to carry out mud circulation, also need to carry out air circulation in air drilling situation, the unit head matching with drilling or power swivel are the necessary devices that carries out mud or air circulation; Guarantee the intact operation of equipment in order to overcome drilling pressure, the washpipe packing device sealing of power swivel is had to higher requirement.Existing unit head washpipe packing apparatus structure is packing compression type, compresses respectively 3 packings by 4 spacer rings in packing box, holds washing pipe tightly and carry out the sealing of mud after packing extrusion-deformation, and this structure is suitable for ￠ 80mm with interior sealing caliber; Concerning be greater than ￠ 80mm rush close sealing, the dimensional accuracy of Sealing processing is difficult for guaranteeing, the material of packing is mixed by the water-fast rubber of oil resistant and canvas, its hardness is really up to the mark, after assembling compresses, non-homogeneous expansion is even, because packing in assembly process often needs to be pressed very tightly, to guarantee its sealability, the bad grasp of compression degree of packing, when washing pipe sealing in assembly process, the excessive sealed packing of pressure is easily extruded distortion, and sealed packing after distortion is fragile to be produced seal failure to leak; For the more wayward assembly process of slightly large diameter washing pipe, must repeatedly assemble and just can reach the most basic requirement, increase the cycle of installation and debugging, affect working efficiency.
Summary of the invention:
The purpose of this utility model is to provide a kind of adjustable double-action sealing configuration unit head washpipe packing device that adopts, and it installs, dismantles efficient and convenient, without compressing completely, can meet the unit head of all size and the washpipe packing of water tap.
The utility model is to realize by following technical solution above-mentioned purpose:
This Novel power head washpipe packing device comprises packing box, sealed packing, sealing caulking ring, lubrication ring, locking plug, it is characterized in that: by upper sealing caulking ring, lubrication and seal spacer ring, double-action sealing caulking ring, lower seal spacer ring, sealed packing is divided into three, each sealing caulking ring is provided with seal groove, the groove mounting O-shaped rings of the cross section semicircular in shape of seal groove, locking plug is equipped with in packing box bottom.
The utility model compared with prior art has following beneficial effect:
1. because the sealed packing in unit head washpipe packing device packing box is divided into three, each sealed packing independence is separately sealed every, four spacer rings of lower seal spacer ring by upper sealing caulking ring, lubrication and seal spacer ring, double-action sealing, effectively reduce the wear area of washing pipe to sealed packing, increased the working life of seal arrangement; Make easy for installationly simultaneously, avoided repeatedly changing sealed packing working efficiency and greatly improved.
2. owing to double-action sealing caulking ring being installed in unit head washpipe packing device, each spacer ring bottom design has semicircle indent to increase cooperation place compaction degree, has improved the reliability of sealing; Use sealing to compress spacer sheet simultaneously, effectively prevented the damage to Sealing after assembling.
Accompanying drawing explanation:
Fig. 1 is unit head washpipe packing device plan view.
Embodiment:
In the packing box (1) of Novel power head washpipe packing device, be provided with successively sealing caulking ring (2), sealed packing (3), lubrication and seal spacer ring (4), sealed packing (3), double-action and seal every (6), sealed packing (3), lower excluder ring (8).Wherein lubrication and seal spacer ring (4) is upper is convenient to sealed packing (3) to be lubricated with lubrication ring (5); Between the semicircular groove sealing caulking ring in bottom of each spacer ring, sealed packing (3) is housed, double-action sealing every (6) outer ring with seal groove mounting O-shaped rings (7), its structure can effective sealing various flows to drilling fluid; Lower seal spacer ring (8) bottom is equipped with O type circle (9) and is prevented that mud from flowing out from packing box (1) joint; Locking plug (10) is equipped with in packing box (1) bottom, by locking plug (10) being installed to guarantee the effective location of washpipe packing device.
While assembling at the scene Novel power head washpipe packing device, successively by packing, spacer ring will be in packing box (1), sealed packing (3) is installed to compression by upper sealing caulking ring (2), lubrication and seal spacer ring (4), double-action sealing every (6) and lower seal spacer ring (8), be loaded on locking plug (10), just can complete location is installed, avoid the poor problem of the bad sealing causing of assembly quality; While changing packing, only need the sealed packing (3) to losing efficacy to change, improved working efficiency.
