Description
Technical field
The utility model is related to band, more particularly to a kind of valve welded type gas-flow closure band.
Background technology
For when buried cable is protected, due to being sealed by sealing ring, thus it is earliest
Technology is to block cable channel using materials such as cement, and the shortcoming of this method is can be because expand with heat and contract with cold between material and pipeline
Ftracture and lose waterproof effect, in addition cable carries out overhauling etc. operating will destroy seal for pipe joints, need to reseal；Furthermore, by
Being blocked by fixation in pipeline needs recovery to destroy whole pipeline, also inconvenient to cable dilatation in the future.For
Overcome grout off extremely sealed existing for above-mentioned deficiency, have devised gas-flow closure band and sealed.Chinese special
A kind of existing gas-flow closure band is disclosed in the patent document of sharp Application No. 2014106902216.Gas-flow closure band bag
The band of hollow structure and the valve cock of the inner space inflation to band are included, valve cock includes the shell of the wall for being arranged in band and positioned at pipe
Gas flow optimized part in shell.The shell of existing gas-flow closure band is sealed connected together with band by way of bonding,
When air pressure is higher, junction easily produces cracking gas leak phenomenon.
Utility model content
The utility model provides a kind of valve cock with the reliable valve welded type gas-flow closure band of connection between band, solution
Determine the problem that existing band junction easily pops.
Above technical problem is solved by following technical proposal：A kind of valve welded type gas-flow closure band, including in
The valve cock that the band of hollow structure and the inner space to band are inflated, the valve cock includes the shell being located on the wall of band, its
It is characterised by, the inner of the shell is provided with dop, and the inner port of the shell is arranged on the dop, close on the dop
Package is wrapped with superficial layer, and the superficial layer is looped around the surrounding of the inner port of the shell, and the superficial layer is along the inner of shell
Mouthful circumferentially extending whole periphery all with the band inner surface sealing welding together.Dop is set so that receive air pressure
Outwardly against during effect, shell is not easy abjection, and then arranges superficial layer and weld together with the inner surface of band and sealed,
Do not allow to be also easy to produce leakage, so as to play a part of to improve sealing anti-pressure ability.
Preferably, the shell is metal structure.It is not easy to be deformed and leakage occur.
Preferably, the outer surface of the band is sealedly connected with the reinforced sheet being set on the shell.Can be further
Valve cock produces cracking phenomena between band when effectively preventing pressure rise.
Preferably, the superficial layer is extended in the inner port of the shell.Compressive resistance raising can further be improved
And the leakage effects for producing.
Preferably, the outer end of the shell be threaded with the wall that coordinates the dop to clamp the band and by shell
With the nut that the band is fixed together.Valve cock can further be improved with the sealing effectiveness between band.
Preferably, the nut includes collar nut body and the internal thread being arranged on nut body inner peripheral surface, institute
The inner peripheral surface for stating nut body is provided with and extends to the groove of the other end along one end of nut, and the groove is by the internal thread edge
The circumferential disconnection of nut body, the nut body is provided through the side side wall rear thread of the groove and is connected to the another of groove
Groove groove width adjusting screw on the wall of side side.Groove groove width adjusting screw is locked after nut check and cause the contracting of groove width
It is little, the result of diminution be the more tightly holding for causing internal thread on shell so that being not easy to produce between nut and shell
Life loosens and causes to send out valve cock connection loosening.
Preferably, the groove has two.The execution that locking effect and will spend screw thread is little.
Preferably, two grooves are uniformly distributed along the circumference of nut body.Nut generation office can effectively be prevented
Portion's fragility phenomenon.
Preferably, the outer peripheral face of nut body is provided with power-assisted groove.It is convenient when drive nut is rotated.
The utility model tool has the advantage that：Valve cock is good with the anti-pressure ability of the junction of band.
