Just check the serial number information on the safety valve; I guess it’s not the same type of valve
It’s not a safety valve; you can take a look at what each letter represents
A37H-16C; A: stands for safety valve, 3: should be the connection method, but I don’t know what kind of connection it refers to； 7: Slightly open type with wrench, without sealing ； H: Alloy steel ； 16: Work stress ； c: Materials are WCB ZG230-450 and A43H-16C; A: stands for safety valve, 4: flange connection ； 3: Unsealed, with wrench, double spring, slightly open type ； H: Alloy steel ； 16: Work stress ； c: Material WCB ZG230-450 ；
In A37H-16C, there is no indicator for the connection code; both 3 and 7 denote the structural type. 3 refers to a type with unssealed springs, a wrench, and a double spring in a slightly open position, while 7 represents a type with unssealed springs, a wrench, and a slightly open position as well
:L What are the two structural forms of a safety valve? Is this a double-headed safety valve? That’s a possibility too! Hehe! How about sending a picture first to take a look!
:It seems that steam and water have used this Y-type safety valve! But I really haven’t seen it yet! If you have the permission, why not send a picture of the actual item? I’ll give it a try too!
He uses both forms together; in other words, 3 serves as a supplementary explanation to 7. I’m not sure if this makes sense
I don’t have any pictures here, but I can explain it to you. It’s two A47 safety valves connected together; a similar type of valve is the A38, which consists of two A48 valves connected in parallel. The number 3 indicates that it’s a dual-spring design. I think that makes it clear now
