Abstract
This utility model relates to a kind of compressed natural gas with check valve and unloads device of air, including the ready-packaged joint being connected with CNG Steel cylinder cart, ready-packaged joint is connected with one end of high-pressure rubber pipe, the other end of high-pressure rubber pipe is connected with pipeline of unloading by rubber hose coupling, check valve and high-pressure ball valve it has been sequentially connected in series on pipeline from left to right unloading, right end at pipeline of unloading is provided with the flange being connected with decompressor, simultaneously, on pipeline of unloading between rubber hose coupling and check valve, exhaust stack is installed, exhaust stack is provided with and diffuses ball valve.This utility model solves when CNG Steel cylinder cart substitutes, the problem that the gas reversely charging in second car enters previous car and valuable gases is diffused in air, reduces waste and the input of manpower of CNG.
Description
Technical field
This utility model belongs to natural gas facility technical field, and a kind of compressed natural gas with check valve unloads device of air.
Background technology
When CNG (Compressed Natural Gas) decompressor has multiple import, need in turn by the CNG in tank car
Being discharged in regulator, CNG passes sequentially through check valve, CNG is discharged in decompressor by main valve, treats in one of them tank car
Gas unloads to the greatest extent, need to be opened by diffusion valve, is diffused by the gas in flexible pipe and flexible pipe of unloading and in main pipeline.After this, need by
Another tank car is connected with another unloading unit, and by that analogy, operator are often the main valve of each unloading unit all
Open, in the case of unloading unit does not has check valve, the gas reflux in a rear car will be made to enter car above, cause
Car residual air before increases.It addition, in the case of the diffusion valve of the unloading unit being not turned off above, also can make below
Gas in tank car diffuses in air by this exhaust stack, causes waste.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, and proposes a kind of compressed natural gas with check valve and unload gas dress
Put.
This utility model solves it and technical problem is that and take techniques below scheme to realize:
A kind of compressed natural gas with check valve unloads device of air, including the ready-packaged joint being connected with CNG Steel cylinder cart, ready-packaged joint
Being connected with one end of high-pressure rubber pipe, the other end of high-pressure rubber pipe is connected with pipeline of unloading by rubber hose coupling, unload on pipeline by
Left-to-right has been sequentially connected in series check valve and high-pressure ball valve, and the right end at pipeline of unloading is provided with the flange being connected with decompressor,
Meanwhile, the pipeline of unloading between rubber hose coupling and check valve is provided with exhaust stack, exhaust stack is provided with and diffuses ball valve.
And, in the termination of described exhaust stack, threeway is installed.
Advantage of the present utility model and good effect be:
1, this utility model solves when CNG Steel cylinder cart substitutes, and the gas reversely charging in second car enters previous car and useful
Gas diffuses this problem in air, reduces waste and the input of manpower of CNG
2, the material investment expense that this utility model is used is low, practical.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Implementing to be further described to this utility model below in conjunction with accompanying drawing, following example are illustrative, are not limited
, it is impossible to limit protection domain of the present utility model with this.
A kind of compressed natural gas with check valve unloads device of air, as it is shown in figure 1, include the fast attaching being connected with CNG Steel cylinder cart
1, ready-packaged joint is connected with one end of high-pressure rubber pipe 2, and the other end of high-pressure rubber pipe is by rubber hose coupling 8 and pipeline of unloading even
Connecing, be sequentially connected in series check valve 7 and high-pressure ball valve 6 from left to right unloading on pipeline, the right end at pipeline of unloading is provided with
The flange 5 being connected with decompressor, meanwhile, the pipeline of unloading between rubber hose coupling and check valve is provided with exhaust stack,
It is provided with on exhaust stack and diffuses ball valve 4.
In of the present utility model being embodied as, in the termination of described exhaust stack, threeway 3 is installed, is used for connecting distal exit.
Operation principle of the present utility model
Quantity according to decompressor import selects supporting unloading unit, and this explanation has as a example by two imports by decompressor.Will
The ready-packaged joint of one of them unloading unit is connected with tank car gas outlet, opens unloading unit main valve i.e. high-pressure ball valve, closes
Diffusing and use ball valve, CNG passes sequentially through check valve, CNG is discharged in decompressor by high-pressure ball valve, treats that in this tank car, gas unloads
To the greatest extent, diffusion valve need to be opened, the gas in flexible pipe and flexible pipe of unloading and in main pipeline is diffused.
After this, need to be connected with another unloading unit by another tank car, operator are often two unloading units
Main valve is all opened, and in the case of not having check valve, the gas reflux in second car will be made to enter first on unloading unit
Car, causing first car residual air increases.It addition, in the case of the diffusion valve being not turned off first unloading unit, also can
Make the gas in second tank car diffuse in air by this exhaust stack, cause waste.
This utility model solves when CNG Steel cylinder cart replaces, and the gas reversely charging in second car enters previous car and valuable gases
Diffusing this problem in air, reduce waste and the input of manpower of CNG, meanwhile, the material that this utility model is used is thrown
Rate are low, practical.
Claims (2)
1. one kind is unloaded device of air with the compressed natural gas of check valve, it is characterised in that: include fast with what CNG Steel cylinder cart was connected
Joint, ready-packaged joint is connected with one end of high-pressure rubber pipe, and the other end of high-pressure rubber pipe is connected with pipeline of unloading by rubber hose coupling,
Being sequentially connected in series check valve and high-pressure ball valve on pipeline from left to right unloading, the right end at pipeline of unloading is provided with and reduces pressure dress
Put the flange of connection, meanwhile, the pipeline of unloading between rubber hose coupling and check valve is provided with exhaust stack, exhaust stack is pacified
Equipped with diffusing ball valve.
