Pressure gauge is connect, switch valve is provided between intermediate tube and four-way pipe fitting, the first desorption tube is connected with first interface, the second desorption tube
It is connected with second interface, can be connected by crossover sub between first interface and second interface.
Further.First desorption tube, intermediate tube and the second desorption tube as described above are metal hose.
Further.Diffusion valve on first interface as described above and/or second interface connection valve pit.
Further.First interface as described above and/or second interface connect the release on valve pit by crossover sub
Valve.
Further.Crossover sub both ends as described above have different sizes or shape.
It uses, utilizes compared with prior art, the utility model has the beneficial effects that the present apparatus is integrated by kit
Crossover sub connects the diffusion valve and interface of various specifications, both can also balance the gas between different pipelines with diffused gas
Pressure.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the use reference example figure of the utility model.
The label in accompanying drawing is: 1. first interfaces；2. the first desorption tube；3. switch valve；4. pressure gauge；5. four-way pipe fitting；

Specific embodiment
Be described in detail below with reference to embodiment referring to attached drawing, so as to the technical characteristics of the utility model and advantage into
Row deeper into annotation.
As shown in Figs. 1-2, the bleeding device of a kind of bypass pipe of the utility model is applied to operation operation release ventilation work
Make a little, the desorption tube including several different size models, specially include the first desorption tube 2, intermediate tube 7 and the second desorption tube 6,
First desorption tube 2, intermediate tube 7 and the second desorption tube 6 are connected by four-way pipe fitting 5, which is also connected with pressure
Table 4 is provided with switch valve 3 between intermediate tube 7 and four-way pipe fitting 5, the first desorption tube 2 is connected with first interface 1, the second desorption tube
6 are connected with second interface 8, can be connected by crossover sub between first interface 1 and second interface 8.
Further, first desorption tube 2, intermediate tube 7 and the second desorption tube 6 are metal hose, are convenient for carrying
With use.On the one hand, the first interface 1 and/or second interface 8 connect the diffusion valve on valve pit 9；On the other hand, described
First interface 1 and/or second interface 8 pass through crossover sub connect valve pit 9 on diffusion valve.The crossover sub both ends tool
There is different size or shapes, be used as accessory, solves the problems, such as that the diffusion valve of plurality of specifications model needs to be equipped with more set desorption tubes.
As shown in Fig. 2, the present apparatus is applied at the valve pit 9 of buried pipeline, first interface 1 is separately connected with second interface 8
At the first diffusion valve 10 and the second diffusion valve 12 on pipeline, the release valve hand handle on buried pipeline is slowly opened, it will be buried
Gas in pipelines pressure carries out release emptying by intermediate tube 7, completes release operation.Buried pipeline is sent after the completion of operation
Gas closes the switch valve 3 for diffusing valve and intermediate tube 7, opens first diffusion valve 10 and the second diffusion valve 12 at both ends respectively,
After checking that the pressure of pressure gauge 4 reaches consistent balance, slowly closes both ends and diffuse valve, right gas is to the ball on intermediate buried pipeline
Valve 11 is slowly opened, this subjob is completed.
In utility model device, four-way pipe fitting 5, pressure gauge 4 and various valves etc. are the prior art or material, affiliated
Technical staff according to required product type and specification, can directly be bought from market or tailor-made.
It should be noted that it can directly on the other element when element is referred to as " being fixed on " another element
Or there may also be elements placed in the middle.When element is considered on " being mounted on " another element, it can be directly installed on separately
On one element or there may also be elements placed in the middle.When an element is considered as " connection " another element, it can be with
It is directly to another element or may be simultaneously present centering elements.
Clear, complete description is carried out to the utility model by the technical solution in above embodiments, it is clear that described
Embodiment be the utility model a part embodiment, instead of all the embodiments.Based on the implementation in the utility model
Example, every other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to
The range of the utility model protection.
