Using the technical solution of the utility model, the seal of valve uses PTFE material, and being adapted to high purity chemical fluid should
With；Main material passes through milled processed, and corrosion resistance is greatly improved；When joint disconnects, valve element is closed automatically, prevent leakage；
After joint connection, valve is automatically turned on, and in nominal working range, remains the unobstructed of fluid；Reliable ball latch mechanism is by phase
The two halves of matching are partially bonded together；Round table-like head is compared to the head of depression arc, and runner has been reduced, but processing letter
Easily, durable, effect is very good in impact of the resistance high-velocity fluid with the slow pulse of solution, and with the multi-layer sealed guarantor of plug inwall
Shield measure, improves the performance parameter of snap joint；Valve element connecting portion A is provided with after groove, pre-small post-large to form annular tip, valve
Core O-ring puts in easily, but takes down because tip is withstood, very difficult, difficult for drop-off, lift-off seal effect, and connection
Convenient and swift, intensity is high, resistance to deficient property is good, and operating pressure is up to reachable -40 DEG C to 200 DEG C of 35MPa, high temperature resistant, and plug is used
Number of times is up to 500,000 times.
