来源:http://www.jnlgvf.com/ 日期:2021-09-17 发布人:admin
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

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.
