今天，上海良工阀门中要给大家介绍的是阀门型号编制方法及供货要求，详细如下：
Today, during the sales of Shanghai Lianggong valve , we want to introduce the valve model preparation method and supply requirements, as follows:
1、阀门类型编制办法：根本的是JB308-75，可是如今现已不够用，有适当一部分不能包括在这个规范中。所以，本规范急需修订。
1. Valve type preparation method: the basic is jb308-75, but now it is not enough, and an appropriate part cannot be included in this specification. Therefore, this specification needs to be revised urgently.
2、国外阀门类型编制办法：各国都没有一致的规范，各生产厂家自行编号。
2. Preparation method of foreign valve types: there is no consistent specification in various countries, and each manufacturer numbers it by itself.
例如：3/4“800LBTSA182F304L/304L
For example: 3 / 4 "800lbtsa182f304l / 304L
(1)DN(2)PN(3)一端螺纹另一端承插焊(4)主体资料(5)密封面资料
(1) DN (2) PN (3) thread at one end socket weld at the other end (4) main body data (5) sealing surface data
3、阀门电动设备类型编制办法：JB/T8530-1997
3. Preparation method of valve electric equipment type: JB / t8530-1997
4、通用阀门供货要求：JB/T7928-1999
4. Supply requirements for general valves: JB / t7928-1999
5、阀门象征：GB/T12220
5. Valve Symbol: GB / t12220
6、阀门的根本功能
6. Basic function of valve
(1)强度功能：即承压才能，是PN的1.5倍。
(1) Strength function: i.e. bearing capacity, which is 1.5 times of PN.
(2)密封功能：阀门阻止内漏、外漏的才能，是PN的1.1倍。
(2) Sealing function: the ability of the valve to prevent internal and external leakage is 1.1 times that of PN.
(3)流阻系数：介质流过阀门时的压力丢失。
(3) Flow resistance coefficient: pressure loss when the medium flows through the valve.
(4)动作功能：
(4) Action function:
A、启闭力和启闭力矩，填料力、磨擦力、介质力、加工精度。
A. Hoisting force and moment, packing force, friction force, medium force and machining accuracy.
B、启闭速度，完结一次开启、关闭动作所需的时间。
B. Opening and closing speed, the time required to complete an opening and closing action.
C、动作灵敏感性和可靠性，主要指主动阀门：L、Y、T、A、S、H。
C. Action sensitivity and reliability mainly refer to active valves: l, y, t, a, s and H.
(5)使用寿命：阀门的耐久性。
(5) Service life: durability of the valve.
