For make present invention solves the technical problem that, the technical solution that uses and the technique effect that reaches it is clearer, below
The technical solution of the embodiment of the present invention will be described in further detail in conjunction with attached drawing, it is clear that described embodiment is only
It is a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those skilled in the art exist
The every other embodiment obtained under the premise of creative work is not made, shall fall within the protection scope of the present invention.
As shown in figure 3, present embodiments providing a kind of process gas conveying cleaning systems, including process gas conveying equipment
15 and blowing pipeline device, blowing pipeline device therein includes negative-pressure vacuum module and positive pressure purging module.Specifically, as schemed
1 to shown in Fig. 3, and negative-pressure vacuum module includes passing sequentially through the first non-return valve 3, the first pressure gauge 4 that the first pipeline 1 connects from beginning to end
Further include the branch line 2 being connected between first pressure gauge 4 and the first diaphragm valve 5 with the first diaphragm valve 5, on branch line 2
It is provided with the second diaphragm valve 6, the free end of branch line 2 connects vacuum pump 7.Negative-pressure vacuum module is used for before using to technique
The vacuum pumping of gas transportation facilities 15 vacuumizes completion until the pressure value in first pressure gauge 4 to -14.7psi, this
Sample the gas in process gas conveying equipment 15 all can be discharged, the easy to operate and used time is very short, saves by vacuumizing
Time cost.It includes passing sequentially through third diaphragm valve 9, the second pressure gauge that the second pipeline 8 connects from beginning to end that positive pressure, which purges module,
10, surge tank 11, the 4th diaphragm valve 12 and the second non-return valve 13.Surge tank 11 has energy storage effect, is opening third diaphragm valve 9
The nitrogen in Nitrogen source gases 16 is stored in surge tank 11 afterwards, when the pressure value in second pressure gauge 10 reaches 80psi, surge tank 11
Interior nitrogen has sufficiently large impact force, opens the 4th diaphragm valve 12 and the first diaphragm valve 5 at this time, can be easily by work
Residual impurity in 15 pipeline of skill gas transportation facilities cleans away.Further, temperature control heating is additionally provided in surge tank 11

Road, and there is open and close limit and status display function.Such valve is acidproof, it is alkaline-resisting, without leakage, not microbiological contamination, easily disinfection and
It is easy to maintain.
Further, in order to make blowing pipeline device more securely be connected on process gas conveying equipment 15, and position
Properly, it occupies little space, blowing pipeline device further includes first substrate and second substrate, and first substrate and second substrate, which are fixed, to be connected
It is connected on the siding of process gas conveying equipment 15, negative-pressure vacuum module is detachably connected on first substrate, and positive pressure purges mould
Group is detachably connected on second substrate, in this way in the case where blowing pipeline device damages, can also be disassembled and be tieed up
It repaiies or replaces.
Further, third diaphragm valve 9, the 4th diaphragm valve 12 and the second non-return valve 13 are managed by VCR connectors and second
Road 8 connects, and the first non-return valve 3 and the first diaphragm valve 5 are connect by VCR connectors with the first pipeline 1, and the second diaphragm valve 6 also leads to
VCR connectors are crossed to connect with branch line 2.The full name in English of VCR is Vacuum Coupling Radius Seal, i.e. vacuum connects
Sagittal plane seal nipple is connect, VCR connectors are one kind of face seal nipple, and sealing element uses metal gasket.Pass through internal and external screw thread
It interlocks to oppress metal gasket, so that gasket is generated certain deformation, to achieve the effect that sealing.High (the group of VCR connectors cleanliness factor
Part is by the process such as electropolishing and cleaning), good airproof performance because using metallic seal element, the specified work of VCR connectors
It is relatively wider (using the VCR connectors of SUS316L gaskets, temperature rating is up to 537 DEG C) to make temperature range.VCR connectors are convenient for peace
Dress has minimum dismounting gap, (can be reinstalled after dismounting with repeated disassembled and assembled and need replacing new gasket).Second pipeline 8, first
Pipeline 1 and branch line 2 are stainless steel pipes.
The course of work of process gas conveying cleaning systems provided in this embodiment is as follows:
Third diaphragm valve 9 is first connected into 16 end of Nitrogen source gases, 13 Joining Technology gas transportation facilities 15 of the second non-return valve
Air inlet, negative pressure vacuumize the gas outlet of module Joining Technology gas transportation facilities 15.Before carrying out cleaning works, at all valves
In opening state, temp auto-controlled heat tape is opened.(a) third diaphragm valve 9 and the 4th diaphragm valve 12 are closed, the second diaphragm valve is opened
6, then start vacuum pump 7;(b) observe first pressure gauge 4 pressure value, when first pressure gauge 4 pressure value stabilization-
When 14.7psi, the second diaphragm valve 6 is first closed, it is rear to open third diaphragm valve 9, so that high pure nitrogen is filled with surge tank 11, temp auto-controlled electricity
Heating tape is in heated condition (30 DEG C of constant temperature).When the pressure value of second pressure gauge 10 reaches 80psi, third diaphragm is first closed
Valve 9, rear to open the 4th diaphragm valve 12 and the first diaphragm valve 5, the big flow nitrogen with thermal energy pours process gas conveying equipment
In 15 pipeline, moisture, oxygen and the impurity particle in pipeline are displaced.After continuously repeating (a) and (b) step 20-30 times, work
Gas outlet connection moisture, oxygen and the grain analyser of skill gas transportation facilities 15, are tested.
The blowing pipeline apparatus structure of the present embodiment is simple, and the cleaning time is short, and effect is good, and nitrogen consumption greatly reduces,
Production cost substantially reduces.
