Scope

GB/T 12222-2023 is the English-translated version of 多回转阀门驱动装置的连接.

GB/T 12222-2023 is the Chinese standard "Multi-turn valve actuator attachments".

Its scope clause reads: This document specifies the relevant requirements for the connection of multi-turn or linear actuators connected to valves: --- Flanges necessary for multi-turn drives connected to industrial valves [see Figure 1a)] or intermediate supports [see Figure 1b)] size; ---The structural form and size of the driving part of the multi-turn drive device necessary to connect with the driven part; --- The reference value of the size of the flange connecting surface directly connected with the industrial valve and the torque and thrust of the connecting flange: This document applies to the connection dimensions of multi-turn valve actuators and valves: Note 1: "Valve" in this document includes "valve with intermediate support" [see Figure 1b)]: Note 2: When the multi-turn driving device is composed of a multi-turn driving device and an integrated multi-turn gearbox or linear travel assembly, the connection is in accordance with this document Provisions, see Figure 1a) and Figure 1b): When the multi-turn drive is composed of a multi-turn drive with a separate multi-turn gearbox or linear When the assembly is composed, the connection of the multi-turn drive connected to the gearbox is in accordance with the provisions of this document, see Figure 1c) and Figure 1d): a) direct connection b) intermediate support connection c) combined direct connection d) combined intermediate support connection Description of index number: 1---Multi-rotary or linear driving device; 5---Gear box; 2---connection surface; 6---connection surface; 3---valve; 7---multi-turn drive device: 4--- There is a support connection in the middle; Figure 1 The connection surface between the multi-turn/linear drive device and the valve.

1 Scope

This document specifies the relevant requirements for the connection of multi-turn or linear actuators connected to valves:

--- Flanges necessary for multi-turn drives connected to industrial valves [see Figure 1a)] or intermediate supports [see Figure 1b)] size;

---The structural form and size of the driving part of the multi-turn drive device necessary to connect with the driven part;

--- The reference value of the size of the flange connecting surface directly connected with the industrial valve and the torque and thrust of the connecting flange:

This document applies to the connection dimensions of multi-turn valve actuators and valves:

Note 1: "Valve" in this document includes "valve with intermediate support" [see Figure 1b)]:

Note 2: When the multi-turn driving device is composed of a multi-turn driving device and an integrated multi-turn gearbox or linear travel assembly, the connection is in accordance with this document

Provisions, see Figure 1a) and Figure 1b): When the multi-turn drive is composed of a multi-turn drive with a separate multi-turn gearbox or linear

When the assembly is composed, the connection of the multi-turn drive connected to the gearbox is in accordance with the provisions of this document, see Figure 1c) and Figure 1d):

a) direct connection b) intermediate support connection c) combined direct connection d) combined intermediate support connection

Description of index number:

1---Multi-rotary or linear driving device; 5---Gear box;

2---connection surface; 6---connection surface;

3---valve; 7---multi-turn drive device:

4--- There is a support connection in the middle;
