Detailed description of the invention
Core of the present utility model is to provide a kind of leak detection device, and this leak detection device can carry out positioning searching accurately to pipeline gas leakage.
In order to make those skilled in the art person understand the utility model scheme better, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Refer to Fig. 1, the schematic front view of the leak detection device that Fig. 1 provides for the utility model embodiment.The leak detection device that the utility model embodiment provides mainly comprises sealing gasket 1 and sleeve pipe 2, sealing gasket 1 has the through hole for being enclosed within pipeline, the two ends of sleeve pipe 2 are all furnished with sealing gasket 1, and hermetic seal is connected between sleeve pipe 2 with sealing gasket 1, sleeve pipe 2 is provided with the steam vent 4 for connecting gas alarm instrument.
When the leak detection device that the utility model embodiment provides is applied on liquid chlorine throwing device, the sleeve pipe 2 of the leak detection device that the utility model embodiment provides can be enclosed within the pipeline of liquid chlorine throwing device, and sealing gasket 1 also can be enclosed within above-mentioned pipeline, hermetic seal between sealing gasket 1 and pipeline, and between sealing gasket 1 with sleeve pipe 2, hermetic seal is connected.If pipeline leaks gas, then gas will enter in the interlayer of sleeve pipe 2 or leak detection device by the leakage hole above pipeline, thus the gas revealed will flow to steam vent 4, steam vent 4 is connected with gas alarm instrument, if the air leakage of pipeline gas leakage reaches the predetermined threshold value of gas alarm instrument, gas alarm instrument will be reported to the police, and gas alarm instrument herein can arbitrarily be changed as required.Due to the leak detection device that the utility model embodiment provides, mainly comprise sleeve pipe 2 and the movement convenient relative to pipeline of sealing gasket 1, two parts, thus the positioning searching to pipeline gas leakage can be realized.
The diameter of sleeve pipe 2 can be designed as the diameter of the through hole much larger than sealing gasket 1 herein, for the leaking gas conduit with different-diameter, can change the detection that the sealing gasket 1 with different through-hole diameter realizes leaking gas to pipeline.Can certainly with the size of other attainable modes diameter of adjusting sleeve pipe 2 at any time in the course of the work, the mode of the diameter of these adjusting sleeve pipes 2 that can expect is included in protection domain of the present utility model.
Sealing gasket 1 can be designed to the sealing gasket of annular, the sealing gasket processing of annular is relatively convenient.Can sealing gasket 1 be designed to split type, namely be made up of fractional part, the sealing gasket with through hole that the formation one that is finally grouped together is complete.Specifically can limit sealing gasket 1 to be made up of two semi-rings, design is unlikely to make the part of sealing gasket 1 too on the high side like this, the part of sealing gasket 1 trouble relatively that combines on the high side; And be made up of two semiorbicular sealing gaskets, then can arbitrarily change sealing gasket 1 according to the diameter of testing pipes easily, use flexible.
As shown in Figures 2 and 3, can be provided with bayonet socket 6 in the periphery of sealing gasket 1, the end of sleeve pipe 2 is provided with the projection 5 coordinated with above-mentioned bayonet socket 6.When being connected with sleeve pipe 2 by sealing gasket 1, the projection 5 arranged by sleeve pipe 2 end is stuck in the bayonet socket 6 of sealing gasket 1 periphery, thus not only achieves sealing gasket 1 and the connection of sleeve pipe 2, also achieves sealing between the two.Projection 5 and bayonet socket 6 are connected together, and the connection between sealing gasket 1 and sleeve pipe 2 can be made more stable.
Bayonet socket 6 can be evenly distributed on the periphery of sealing gasket 1, and protruding 5 are cooperatively distributed in the end of sleeve pipe 2 with above-mentioned bayonet socket 6.The quantity of the bayonet socket 6 of sealing gasket 1 periphery can be specially 6, and the quantity of the projection 5 of sleeve pipe 2 one end also can match with bayonet socket 6 and is set to 6.Certainly, other quantity bayonet socket 6 and other quantity projection 5 are all allowed to.And bayonet socket 6 is also not necessarily evenly distributed on the periphery of sealing gasket 1, projection 5 is also not necessarily evenly distributed in the both ends of sleeve pipe 2.
Said is herein that sealing gasket 1 is connected together by bayonet socket 6 and protruding 5 with sleeve pipe 2, and certainly, sealing gasket 1 and sleeve pipe 2 select other hermetic seal connected mode to be also contained in protection domain of the present utility model.
As shown in Figure 3, the shape of the cross section of above-mentioned bayonet socket 6 can be specially trapezoidal, and trapezoidal upper base is positioned at the edge of sealing gasket 1, the profile design of the cross section of the projection 5 of one end of sleeve pipe 2 is the shape (as shown in Figure 2) corresponding with above-mentioned bayonet socket 6.As can be seen from Figure 3, the width of the side of the through hole of the close sealing gasket 1 of bayonet socket 6, wider than the width of the side of the through hole away from sealing gasket 1, can make the projection 5 of sleeve pipe 2 end be stuck in firmly in bayonet socket 6.The shape of the cross section of bayonet socket 6 also can select other set-up mode.
As shown in Figure 2, opening 7 for being enclosed within pipeline can be had in the axis of sleeve pipe 2, and the draw-in groove 3 both ends of the surface forming opening 7 on sleeve pipe 2 are respectively equipped with for sealed open 7 and lug boss, lug boss is stuck in draw-in groove 3.Have opening 7 in the axis of sleeve pipe 2, sleeve pipe 2 just can be enclosed within pipeline from its opening 7 easily.
Can be provided with along its axial arranged corrugated surface at the outer peripheral face of sleeve pipe 2, by the corrugated surface on sleeve pipe 2, sleeve pipe 2 can realize stretching freely along its axis or contraction easily.The design of this kind of structure, not only saves the space that sleeve pipe 2 is enclosed within shared pipeline on pipeline, and flexibly and easily, achieves and determine segment search to the location of different length leaking gas conduit.
Above leak detection device provided by the utility model is described in detail.Apply specific case herein to set forth principle of the present utility model and embodiment, the explanation of above embodiment just understands method of the present utility model and core concept thereof for helping.Should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model principle, can also carry out some improvement and modification to the utility model, these improve and modify and also fall in the protection domain of the utility model claim.
