Slide Seal – Low-temperature Quick Sample Change Method
Components
A complete set of “low-temperature quick sample change” solutions includes the following parts:
Probe Modification & SlideSeal Component
PN.
·Sleeve·Replacement Chamber + Gate Valve
PN.
Air System
PN.
➡ A thin-walled stainless steel sleeve needs to be added to the probe;
➡ Adding a sliding seal assembly to ensure that the probe does not break the vacuum during vertical movement;
➡ Consists of sleeve and gate valve;
➡ The plate valve is used to isolate the vacuum chamber and the atmosphere;
➡ The sleeve is used to serve as an air washing chamber for quick insertion and extraction of the probe;
➡ The process of pumping and inflating is controlled by the vacuum valve;
Working Principle & Operation Process
The Probe And Slide Seal Assembly Have Been Assembled Before Delivery
1.Probe Installation
➡ Close the gate valve;
➡ Install the probe, and install the sliding parts and sleeve together;
2.Gas Washing Operation
➡ Close all valves (A, B, C, D);
➡ Turn on the vacuum pump, open valve-D, valve-B, and valve-A in sequence. Pump out the air to a value less than the rated value;
➡ Close valve-D, open valve-C and fill Helium to about 0.5 atm;
➡ Close valve -C, open valve -D, and pump out the gas to less than the rated value;
➡ Repeat steps 3-4 to complete the gas washing;
3.Put It Into The Cryogenic Chamber
➡ Close valve-D, valve-B, valve-A in turn, and close the vacuum pump;
➡ Open gate valve and install the probe into the cryogenic chamber;
