Abstract
The utility model belongs to Sand-washing in Oilfield implement field, more particularly to a kind of quick sand washing connector, including central tube and pressure cap, pressure cap is sleeved on the outside of central tube, and the lower end of central tube is provided with sealing section, seals and sealing element is provided on the outside of section, the sealing element is O-ring seal, the diameter of section of O-ring seal is not less than 5mm, and the both sides of the pressure cap are each provided with a rod-shaped handle, and handle is threadedly attached on pressure cap.During using the utility model, sealing section is inserted into oil pipe first, then handle is pulled with hand to tighten pressure cap, as a result of insertion sealed, to pressure cap tighten degree requirement it is very low, therefore sand washing connector is easier for installation, the set-up time is also shortened, so as to shorten the time of sand washing operation.The utility model hand can be installed, and avoid damage of the pipe wrench to device.The utility model, as sealing element, thoroughly avoids leakage using O-ring seal.
Description
Technical field
The utility model belongs to Sand-washing in Oilfield implement field more particularly to a kind of quick sand washing connector.
Background technology
During oilfield downhole operation, probably due to sand production in oil, which generates sand, buries well section, just need to carry out sand washing at this time
Operation.Under normal conditions, the elbow that sand washing uses using 21/2TBG button-types connect, due to directly using be threadedly coupled into
Row sealing, needs to be tightened with pipe wrench, then could carry out sand washing operation when installing sand washing elbow.Each connection procedure needs 3 points
Clock or so, at the same time, the oil reservoir sand that oil jacket annular space has been rushed can be fallen after rise rapidly, seriously affected sand washing effect, reduced sand washing
Efficiency, activity duration are also long.To solve the above-mentioned problems, notification number is provided for the utility model patent of CN202064882U
A kind of sand washing connector of fast demountable.However, this sand washing connector still has obvious shortcoming：On the one hand, this sand washing
Connector will not be compressed, i.e., packing element is not whithin a period of time using the sealing means of compression packing element in pressure ascent stage packing element
It seals, therefore there are problems that sand cleaning fluid leaks on a small quantity；On the other hand, boss is provided on the device only pressure cap, is led to
It crosses and pulls boss and be inconvenient to turn pressure cap, and boss can occupy larger space, be unfavorable for the storage of device.
Invention content
The utility model provides a kind of quick sand washing connector, to solve the problems mentioned in the above background technology.
The technical issues of the utility model solves is realized using following technical scheme：The utility model provides a kind of fast
Fast sand washing connector, including central tube and pressure cap, pressure cap is sleeved on the outside of central tube, and the lower end of central tube is provided with seal area
Section, seals and sealing element is provided on the outside of section, and the sealing element is O-ring seal, and the diameter of section of O-ring seal is not small
In 5mm, the both sides of the pressure cap are each provided with a rod-shaped handle, and handle is threadedly attached on pressure cap.
During sealing, the decrement of O-ring seal is 0.5-1mm.It is additionally provided on the outside of the sealing section by nylon
Manufactured wear ring, wear ring are arranged on the downside of O-ring seal.
The beneficial effects of the utility model are：
When the 1st, using the utility model, sealing section is inserted into oil pipe first, then handle is pulled with hand and twists pressure cap
Tightly, as a result of insertion sealed, to pressure cap to tighten degree requirement very low, therefore sand washing connector is easier for installation,
Also the set-up time is shortened, so as to shorten the time of sand washing operation.
2nd, the utility model hand can be installed, and avoid damage of the pipe wrench to device.
3rd, the utility model compared with packing element of the prior art, is thoroughly avoided using O-ring seal as sealing element
Leakage.
4th, sealing element is vulnerable part, and O-ring seal is of low cost, therefore maintenance cost is lower.
5th, compared with prior art, dismounting other parts are not needed to when O-ring seal is replaced, therefore are repaired quicker.
6th, compared with boss structure of the prior art, rod-shaped handle is more effortless, meanwhile, handle can be torn open when not in use
Under to save memory space.
7th, the setting of wear ring can effectively strike off the impurity on tube inner wall, so as to play a protective role to O-ring seal.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
In figure：1- central tubes, 2- handles, 3- pressure caps, 4- wear rings, 5- sealing sections, 6-O type sealing rings.
Specific embodiment
The utility model is described further below in conjunction with attached drawing：
The present embodiment includes central tube 1 and pressure cap 3, and pressure cap 3 is sleeved on the outside of central tube 1, the lower end setting of central tube 1
There is sealing section 5, the outside of sealing section 5 is provided with sealing element.It is above already existing structure in the prior art, herein not
It repeats again.
The sealing element is O-ring seal 6, using O-ring seal 6 as sealing element, with packing element of the prior art
It compares, thoroughly avoids leakage.Sealing element is vulnerable part, and O-ring seal 6 is of low cost, therefore maintenance cost is lower.Separately
Outside, compared with prior art, dismounting other parts are not needed to when O-ring seal 6 is replaced, therefore are repaired quicker.
The diameter of section of O-ring seal 6 is not less than 5mm, and during sealing, the decrement of O-ring seal 6 is 0.5-1mm.Ensure
The sealing effect of O-ring seal 6
The both sides of the pressure cap 3 are each provided with a rod-shaped handle 2, and handle 2 is threadedly attached on pressure cap 3.
Compared with boss structure of the prior art, rod-shaped handle 2 is more effortless, meanwhile, handle 2 can be removed to save when not in use
Memory space.The utility model hand can be installed, and avoid damage of the pipe wrench to device.
Wear ring 4 made of nylon are additionally provided on the outside of the sealing section, wear ring 4 is arranged on O-shaped sealing
The downside of circle 6.The setting of wear ring 4 can effectively strike off the impurity on tube inner wall, make so as to play protection to O-ring seal 6
With.
During using the utility model, sealing section 5 is inserted into oil pipe first, then handle 2 is pulled with hand and twists pressure cap 3
Tightly, as a result of insertion sealed, to pressure cap 3 to tighten degree requirement very low, therefore sand washing connector is easier for installation,
Also the set-up time is shortened, so as to shorten the time of sand washing operation.
