Description
Technical field
It the utility model is related to oil-gas pipeline plugging valves instrument, and in particular to a kind of all sealing valve blocking clamper.
Background technology
On natural gas transportation pipeline, the leakage of pressure guiding pipe root valve happens occasionally.The place of leakage may have many kinds：Valve
Leakage, valve body itself leakage etc. at screw thread between bar and the leakage of valve body junction, valve body and pressure guiding pipe.And the company of root valve
Junctor also differs, and some heel pressure table connections, some is connected with ball valve, and some is connected with pressure transmitter.Different leakages
Situation, there is different processing methods.It is well known that pipeline is high-pressure natural gas, belong to inflammable and explosive medium, once let out
Leakage be easy to cause big security risk.For safety, such issues that processing, traditional method was stopping transportation, emptying, the valve more renewed
Door, so does the normal operation for not only seriously affecting pipeline, and be bound to cause the substantial amounts of wasting of resources.So without
In the case that stopping transportation is replaced, if the fact that smaller diameter valve leakage and relatively small leakage rate, blocked with fixture
It is very safe, economical, efficient.
The prior art is that the valve of single leak source is sealed with fixture, there is a situation where multiple leak sources just not for a valve
It is applicable in.And existing fixture, the fully wrapped around rear progress greasing sealing of valve, such valve are mostly lost into on-off action.
Utility model content
The utility model provides a kind of all sealing valve blocking clamper, it is intended to solves to make in the prior art to a certain extent
Can not being applied to valve with fixture sealing, there are the deficiency that multiple leak sources and sealing late gate lose on-off action.
The technical solution that the utility model solves above-mentioned technical problem is as follows：A kind of all sealing valve blocking clamper, its

Connect, make sealing effect more preferable to reduce gap rate.
Further, the Sealing shield ring one and Sealing shield ring two are the circular ring plate for being provided with flanging.
Further, the operation bar body is integrally formed with the operation rod sleeve by stainless steel.
Further, the front end of the operation bar body cuts into flat and is fixedly connected with an operation handle.Behaviour is set
Make handle so that more effortless during by the clamp switch valve and conveniently.
Further, the periphery of the protecgulum and rear cover, which corresponds to, is uniformly provided with multiple screw holes, and matching is set in each screw hole
It is equipped with the fastening bolt for making protecgulum and rear cover cover compression each other.
Compared with prior art, the beneficial effects of the utility model are：
(1) the totally-enclosed property of the fixture allows multiple leak sources of its disposable sealed valve.
(2) manipulating between rod sleeve and Sealing shield ring two and be equipped with ball so that control stick friction is rolling friction,
Greatly reduce its friction so that control stick is more convenient to rotate, and the switch for also allowing for valve is more convenient, while frictional force
Small therefore Sealing shield ring two will not Forced rotation and damage the 3rd elastic seal ring.
(3) do not had to using the fixture by the way of greasing, greatly reduce process and operating time.
(4) device is applicable to a variety of combining form such as root valve and pressure gauge, ball valve or pressure transmitter.
(5) device processing valve leak problem is utilized, it is not necessary to which stopping transportation is largely vented petroleum resources, economic and society's effect
Benefit is considerable.
(6) apparatus structure size is compact, is highly suitable for using during field operation narrow space.
