今天，上海良工閥門中要給大家介紹的是閥門型號編制方法及供貨要求，詳細如下：
Today, during the sales of Shanghai Lianggong valve , we want to introduce the valve model preparation method and supply requirements, as follows:
1、閥門類型編制辦法：根本的是JB308-75，可是如今現(xiàn)已不夠用，有適當(dāng)一部分不能包括在這個規(guī)范中。所以，本規(guī)范急需修訂。
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、國外閥門類型編制辦法：各國都沒有一致的規(guī)范，各生產(chǎn)廠家自行編號。
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)一端螺紋另一端承插焊(4)主體資料(5)密封面資料
(1) DN (2) PN (3) thread at one end socket weld at the other end (4) main body data (5) sealing surface data
3、閥門電動設(shè)備類型編制辦法：JB/T8530-1997
3. Preparation method of valve electric equipment type: JB / t8530-1997
4、通用閥門供貨要求：JB/T7928-1999
4. Supply requirements for general valves: JB / t7928-1999
5、閥門象征：GB/T12220
5. Valve Symbol: GB / t12220
6、閥門的根本功能
6. Basic function of valve
(1)強度功能：即承壓才能，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：閥門阻止內(nèi)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)流阻系數(shù)：介質(zhì)流過閥門時的壓力丟失。
(3) Flow resistance coefficient: pressure loss when the medium flows through the valve.
(4)動作功能：
(4) Action function:
A、啟閉力和啟閉力矩，填料力、磨擦力、介質(zhì)力、加工精度。
A. Hoisting force and moment, packing force, friction force, medium force and machining accuracy.
B、啟閉速度，完結(jié)一次開啟、關(guān)閉動作所需的時間。
B. Opening and closing speed, the time required to complete an opening and closing action.
C、動作靈敏感性和可靠性，主要指主動閥門：L、Y、T、A、S、H。
C. Action sensitivity and reliability mainly refer to active valves: l, y, t, a, s and H.
(5)使用壽命：閥門的耐久性。
(5) Service life: durability of the valve.
