Description
Technical field
The utility model relates to oil addition fields, relate in particular to a kind of grease pouring device.
Background technique
Current high each station of sulfur Gas Fields is each equipped with wellhead assembly, and wellhead assembly contains a valve more than 20, main to wrap
Gate valve containing manual platform and hydraulic flat gate valve, according to related well control administrative provisions, each flat gate valve of wellhead assembly every three
Moon greasing is primary, and can be fully sealed between flat gate valve valve plate and valve seat on the one hand can be ensured by way of greasing,
On the other hand, can by way of greasing, push grease pouring valve Internal steel ball activity, while by the impurity inside grease pouring valve into
Row substitution avoids forming hidden danger because impurity accumulation causes to leak in grease pouring valve inside grease pouring valve.
By taking first height of dam sulfur-bearing station as an example, wellhead assembly contains two kinds of flat gate valve, needs to fill different
Stop-leak compound, but the component that greasing equipment includes is consistent, mainly comprising hand pump, hydraulic oil, stop-leak compound cylinder, filling pipeline,
Shut-off valve and jointing, the stop-leak compound type of filling mainly include Great Wall 7903 and TF-41 two types, filling process
In, filling pipeline is connect with grease pouring valve first, is pressurizeed using hand pump to hydraulic oil, hydraulic oil is by stop-leak compound, by adding
Note pipeline and grease pouring valve enter inside flat gate valve valve chamber, achieve the purpose that greasing.Under normal circumstances, if there are micro- for grease pouring valve
Small leakage or interior leakage can be solved by way of greasing, if there are interior leakages for flat gate valve, can also pass through greasing
Mode solved.But there is also a risks during greasing, after greasing is completed, since grease pouring valve Internal steel ball is living
After dynamic return, do not reach sealing effect, after greasing finishes, leakage in grease pouring valve causes to fill and plays pressure inside pipeline, can not
Disassembly filling pipeline, and greasing pipeline can not directly differentiate inside filling pipeline whether there is interior leakage at present, be only capable of connecing by disassembly
After head, to determine whether there is interior leakage in such a way that opening shut-off valve releases pressure, there are biggish security risks, and are not inconsistent
Close relevant operation regulation.
According to incompletely statistics, domestic sulfur Gas Fields can not be torn open because with pressure inside greasing pipeline caused by leaking in greasing hole every year
The phenomenon that unloading filling pipeline up to up to a hundred leaks up to more than 10 parts by taking the gas field Yuan Ba as an example in grease pouring valve during annual greasing,
In view of well head pressure is generally higher, if according to leakage in current filling pipeline judgement, there are biggish security risks, while
Sulfur-bearing station relevant operation regulation is not met, it is therefore necessary to be transformed to existing greasing pipeline, it is ensured that greasing process safety.
