Description
Technical field
The utility model relates to oil exploitation underground operation tools, specifically continuous sand flushing circulating valve.
Background technique
One of the main reason for sand production is oil well construction, so inspection pump impulse sand is one of conventional workover treatment.
The deficiencies of there are terminations of pumping to make up a joint using conventional sand washing operation, causes outstanding sand sinking easy card tubing string, and this mode is also inconvenient
It shakes out the development of location detecting technology in underground, therefore scene is there is an urgent need to the exploration of not termination of pumping continuous sand flushing, at present continuous sand flushing
There are two types of forms for method：One is coild tubing unit sand washing is used, this needs professional equipment and operating personnel, and scene is inconvenient
It promotes；Another kind is using conventional oil pipe, and commutate continuous sand flushing technology in casing, and this technology is due to reversal valve function list
One, the longer sealing drum of tripping in is needed, site operation is inconvenient, to solve this problem, proposes continuous sand flushing circulating valve.
Utility model content
The purpose of this utility model is to provide continuous sand flushing circulating valve, solve the problems, such as that existing continuous sand flushing exists.Tool
There is a valve dual control and is not easy the characteristics of meeting card.
In order to achieve the above objectives, the utility model uses following technical solution, continuous sand flushing circulating valve, including center
Pipe, circulating sleeve, support sleeve, the central tube open up the upper conversion hole radially penetrated through, lower conversion hole, and center tube cavity is provided with not
Conversion hole, lower conversion hole is allowed to carry out interconnected partition in center tube cavity, the circulating sleeve, support sleeve cover at center
Outside pipe, wherein circulating sleeve lower end connects support sleeve, and circulation set upper side connects elastic component, the upper conversion hole, lower conversion Kong Jun
It is connected to circulating sleeve inner cavity, the circulating sleeve opens up the circulation port radially penetrated through, and barrier ring is arranged in circulating sleeve inner wall, wherein circulation port
Below barrier ring, the support sleeve outer wall is arranged sealing element.
The elastic component is spring, and spring pocket is also arranged adjusting ring, the spring outside central tube outside central tube
Upper end, which is withstood on, adjusts ring lower end surface.
The center pipe outer wall offers the limit frustum that limitation adjusts ring prolapse upwards.
The central tube upper end connects top connection, and lower end connects lower contact.
The utility model has the advantages that compared with prior art：
1, a valve dual control：When valve is in sealing drum, backwash liquid compressive seal, circulating sleeve uplink are converted in sealing
Hole, while it being connected to lower conversion hole and circulation port, circulating liquid can flow out outside valve from central tube, realize conversion function；Work as valve
Not in sealing drum, spring-compressed sealing element, circulating sleeve downlink seal circulation port, while being connected to conversion hole and lower conversion hole,
Circulating liquid can flow to central tube top from central tube lower part, realize that fluid continuously flows in oil pipe.
2, the utility model structure is simple, and linkage is not easy to meet card less.
