Description
Technical field
The present invention relates 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 is also differed, 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 easily causes big potential safety hazard.For safety, traditional method is stopping transportation, emptying, the valve more renewed such issues that processing
Door, so does the normal operation for not only having a strong impact on pipeline, and certainly will cause the substantial amounts of wasting of resources.So without
In the case that stopping transportation is changed, if the fact that smaller diameter valve leakage and relatively small leakage rate, blocked with fixture
It is very safe, economical, efficient.
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.And existing fixture, the fully wrapped around rear progress greasing sealing of valve, such valve are mostly lost into on-off action.
The content of the invention
The present invention provides a kind of all sealing valve blocking clamper, it is intended to solves to a certain extent in the prior art using folder
Tool sealing, which can not be applied to valve, to be had multiple leak sources and seals the deficiency that late gate loses on-off action.
The technical scheme that the present invention solves above-mentioned technical problem is as follows：A kind of all sealing valve blocking clamper, it includes
Cover sets the chuck body of whole leakage valve, and the chuck body includes protecgulum, bonnet and operation rod, the protecgulum with
Bonnet is respectively arranged on the left side and the right side semi-circular through hole, the protecgulum and the bonnet corresponding semi-circular through hole after covering each other
The circular channel passed through for the pipeline of connection leakage valve is spliced to form, the binding face of the protecgulum and bonnet, which is provided with, supplies first
The first seal groove that elastic seal ring is caught in, cartridge seal chamber, sleeve placement are sequentially provided with inside the protecgulum from front to back
Chamber and leakage valve placing chamber, the front-end and back-end of the cartridge seal chamber are correspondingly provided with the second seal groove and the 3rd sealing ring
Groove, the operation rod include operation bar body, operation rod sleeve, Sealing shield ring one and Sealing shield ring two, the action bars
Rear end and the operation rod sleeve that the Sealing shield ring one and Sealing shield ring two and the operation bar body are arranged with body are coaxial
It is fixedly connected, the operation rod sleeve is located in the sleeve placing chamber and is connected with the valve rod of the leakage valve, the behaviour
Make the front end of bar body through the cartridge seal chamber and extend out to outside the protecgulum, the Sealing shield ring one and the sealing gear
Circle two is corresponding to be caught in second seal groove and the 3rd seal groove, is pressed from both sides between the seal groove of Sealing shield ring one and second
Provided with the second elastic seal ring, the 3rd elastic seal ring is folded between the seal groove of Sealing shield ring two and the 3rd.Wherein
The shape of one elastic seal ring should meet the concrete shape of the first seal groove, lead to because the first seal groove have passed through two semicircles
Hole, therefore the first elastic seal ring should correspond to and set two semicircular parts to be caught in corresponding semi-circular through hole (elastic packing herein
Circle abuts with pipeline outer wall).
On the basis of above-mentioned technical proposal, the present invention can also do following improvement.
Further, the external diameter of the operation rod sleeve is more than the external diameter of the operation bar body, the Sealing shield ring two
Multiple balls are folded between the front end face of rear end face and the operation rod sleeve.The quantity of ball is as far as possible more, and ball supports each other
Connect, make sealing effectiveness 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 laborsaving during by the clamp switch valve and conveniently.
Further, the periphery of the protecgulum and bonnet is corresponding uniformly offers multiple screws, matches and sets in each screw
It is equipped with the fastening bolt for making protecgulum and bonnet cover compression each other.
Compared with prior art, the beneficial effects of the invention are as follows：
(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 provided with ball so that control stick friction is rolling friction,
Greatly reduce its friction so that control stick is more convenient to be rotated, and the switch for also allowing for valve is more convenient, while frictional force
Small therefore Sealing shield ring two is also not forced rotation and damages 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.
