Further, the inner side of described connector is provided with a spacing shaft shoulder, and this spacing shaft shoulder is blocked in the outside of described leak detection shutoff, and the spacing shaft shoulder, by spacing in the inner side of connector for leak detection shutoff, prevents leak detection shutoff from shifting out under the action of the spring outside active tunnel.

The utility model in use, connector on housing is connected with pipeline or container, connector on housing also can be connected in the rapid-acting coupling of inflating for container or carry out for aerating device, when there is not gas leakage situation in pipeline or pipeline and rapid-acting coupling, pipeline, air pressure in container or rapid-acting coupling overcomes the power of spring by the afterbody of leak detection shutoff top to active tunnel, now, the first half of leak detection shutoff is relative with viewport, and the latter half of shutoff of hunting leak is away from viewport, the labeling of namely hunting leak on the afterbody of shutoff is away from viewport, spring is compressed simultaneously, when pipeline or container and rapid-acting coupling existing gas leakage, namely the air pressure in pipeline or container and rapid-acting coupling is less than when there is not air pressure in the power of spring or pipeline or container and rapid-acting coupling, spring reset thus by leak detection shutoff top to the head of active tunnel, now, the first half of leak detection shutoff is away from viewport, and the latter half of shutoff of hunting leak is relative with viewport, the labeling of namely hunting leak on the afterbody of shutoff is relative with viewport, thus can gas leakage be known whether by whether labeling is relative with viewport, if that is seen by viewport sees labeling, then represent gas leakage, if cannot see, then represent air tight, detect very convenient.

Whether the beneficial effects of the utility model are: adopt said structure, occur knowing whether pipeline or container and rapid-acting coupling exist gas leak phenomenon in use procedure by labeling at viewport place, extremely easy to use, and simple and compact for structure.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

With reference to Fig. 1, a kind of pipeline, container gas leak detection device, comprise housing 1, an active tunnel 2 is provided with in this housing, the head of this active tunnel has the connector 3 be connected with pipeline or container, leak detection shutoff 4 is slidably equipped with in described active tunnel, the head of this leak detection shutoff is spacing is provided with O-ring seal 1 between the outer wall of the head of described leak detection shutoff and the inwall of described active tunnel in the inner side of described connector, spring 6 is provided with between the afterbody of this leak detection shutoff and the afterbody of described active tunnel, the sidewall of described active tunnel 2 radially runs through the viewport 7 having at least one to be positioned at the rear of described O-ring seal one all the time, a colored labeling 8 is provided with outside the afterbody of described leak detection shutoff, the color of labeling can select redness, more eye-catching like this, this labeling 8 can be relative with described viewport 7 when pipeline or container gas leakage.

In the afterbody of described active tunnel 2, spiral shell is provided with and supports plug 9, the inner end of this support plug is arranged with spring cavity 10, the afterbody of described detection shutoff 4 is provided with spring stack 11, and one of described spring is supported in described spring cavity, and the other end of described spring is sleeved on described spring stack.The position of labeling 8 in leak detection shutoff 4 in active tunnel 2 can regulate by supporting the position of plug 9 in the afterbody of active tunnel 2, thus ensures that labeling 8 is relative with viewport 7 in time when pipeline or container gas leakage.

Be embedded with a seal be made up of hard elastic encapsulant 12 in described connector 3, be provided with through hole 13 in the seal, the outside of this through hole is provided with the little bellmouth 14 in large inner end, outer end, is provided with O-ring seal 2 15 between described seal 12 and described connector 3.Hard elastic encapsulant can be resin material, can be also nylon material, thus make seal 12 also have certain elasticity while having some strength, not only good sealing effect, and substantially prolongs serviceable life.

Described viewport 7 is four, and be distributed on the sidewall of described active tunnel 2, and four described viewports are positioned on same circle, described labeling 8 forms a circle on the afterbody of described leak detection shutoff 4, makes operating personnel can see labeling 8 from all angles by viewport 7 when pipeline or container gas leakage like this.

The outer wall of described housing 1 is arranged with a circle groove 16, described viewport 7 is arranged on the diapire of described groove, saves material.

The inner side of described connector 3 is provided with a spacing shaft shoulder 17, and this spacing shaft shoulder is blocked in the outside of described leak detection shutoff 4, and the spacing shaft shoulder 17, by spacing in the inner side of connector 3 for leak detection shutoff 4, prevents leak detection shutoff 4 from moving down out outside active tunnel 2 in the effect of spring 6.

The utility model in use, connector 3 on housing 1 is connected with pipeline or container, connector 3 on housing 1 also can be connected in the rapid-acting coupling of inflating for container or carry out for aerating device, when there is not gas leakage situation in pipeline or pipeline and rapid-acting coupling, pipeline, the afterbody to active tunnel 2 is pushed up in leak detection shutoff 4 by the power that the air pressure in container or rapid-acting coupling overcomes spring 6, now, the first half of leak detection shutoff 4 is relative with viewport 7, and the latter half of shutoff 4 of hunting leak is away from viewport 7, the labeling 8 of namely hunting leak on the afterbody of shutoff 4 is away from viewport 7, spring 6 is compressed simultaneously, when pipeline or container and rapid-acting coupling existing gas leakage, namely the air pressure in pipeline or container and rapid-acting coupling is less than when there is not air pressure in the power of spring 6 or pipeline or container and rapid-acting coupling, spring 6 resets thus the head to active tunnel 2 is pushed up in leak detection shutoff 4, now, the first half of leak detection shutoff 4 is away from viewport 7, and the latter half of shutoff 4 of hunting leak is relative with viewport 7, the labeling 8 of namely hunting leak on the afterbody of shutoff 4 is relative with viewport 7, thus can gas leakage be known whether by whether labeling 8 is relative with viewport 7, if that is seen by viewport 7 sees labeling 8, then represent gas leakage, if cannot see, then represent air tight, detect very convenient.
