閥門型號(hào)編制方法及供貨要求

來源:http://firstpet.com.cn/ 日期:2021-09-17 發(fā)布人:admin
今天,上海良工閥門中要給大家介紹的是閥門型號(hào)編制方法及供貨要求,詳細(xì)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(gè)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(guó)外閥門類型編制辦法:各國(guó)都沒有一致的規(guī)范,各生產(chǎn)廠家自行編號(hào)。
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(dòng)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(qiáng)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(shí)的壓力丟失。
(3) Flow resistance coefficient: pressure loss when the medium flows through the valve.
(4)動(dòng)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(dòng)作所需的時(shí)間。
B. Opening and closing speed, the time required to complete an opening and closing action.
C、動(dòng)作靈敏感性和可靠性,主要指主動(dòng)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.
