上海凱研機(jī)械設(shè)備有限公司提供閥鎖，閥門聯(lián)鎖，閥門機(jī)械鎖裝置，防止人為誤操作。閥門機(jī)械鎖是安裝與閥門上的鎖定裝置，可以將兩個(gè)或多個(gè)閥門鎖定后，遵循規(guī)定的操作順序進(jìn)行安全有序的操作，防止誤操作導(dǎo)致事故的發(fā)生。

凱研機(jī)械公司提供多種類型的閥門機(jī)械聯(lián)鎖，適用于各種類型的閥門，如：球閥、蝶閥、閘閥、截止閥、電動(dòng)閥、盲板閥及管道收發(fā)球系統(tǒng)。

閥門機(jī)械鎖裝置特點(diǎn)

1、每臺(tái)閥門的裝置上配備兩把不同的帶有編碼的鑰匙，控制閥門的兩種狀態(tài)。

2、裝置上留存兩把鑰匙的條件下，閥門處于可操作狀態(tài)，通過操作實(shí)現(xiàn)鑰匙的轉(zhuǎn)換。

3、裝置上留存一把鑰匙的條件下，閥門處于鎖定狀態(tài)，鑰匙的位置標(biāo)識(shí)閥門的狀態(tài)。

4、通過“鑰匙傳遞”，實(shí)現(xiàn)閥門信息的遠(yuǎn)程傳遞和狀態(tài)顯示。

5、結(jié)構(gòu)緊湊堅(jiān)固，操作靈活簡便。 

6、采用不銹鋼材質(zhì)，產(chǎn)品壽命長久。

7、安裝簡便，不改變受控閥門的性能和形狀，適合于多種類型的閥門。

2、閥門機(jī)械鎖裝置工作原理

初始狀態(tài)

 裝置對應(yīng)的孔位上留存一把鑰匙，受控閥門處于初始狀態(tài)（開或關(guān)）

操作狀態(tài)

根據(jù)工藝要求，從控制室取出授權(quán)鑰匙，插入裝置上另一側(cè)對應(yīng)的孔位，受控閥門處于可操作狀態(tài)，操作閥門至新的狀態(tài)（開或關(guān)）

結(jié)束狀態(tài)

拔出初始狀態(tài)中留存的鑰匙，并返回控制室，受控閥門鎖定于重新設(shè)定的狀態(tài)（開或關(guān)）。

3、應(yīng)用范圍

閥門機(jī)械聯(lián)鎖主要應(yīng)用于 油田、石化、化工、核電、冶金、天然氣等高危行業(yè)中關(guān)鍵閥門的狀態(tài)鎖定、傳遞和顯示（現(xiàn)場和控制室）。

 Inthe actual operation process, it is called ”mechanicalinterlocking" that the key is exchanged in a certain logical orderto realize the safe operation process. It is a kind of mechanicaldevice approved by the world safety organization and standardorganization, which can prevent man-mademisoperation. 

Thepurposeof installing mechanical interlocking is to ensure thatthee and its auxiliary e can operate in accordancewith the process set. In order to eliminate the iueparableconse caused by human error operation. 

Inpetroleum, chemical, powe r and high-risk manufacturing industries,there are a large number of manual operation e, electricale, protective safety doors and so on. Accidents caused bymisoperation are co1mnon, and serious casualties and economiclosses caused by misoperation also occur from time to time.Statistics show that 70% of accidents in the oil and gas industryare caused by human errors. The rapid development of modernindustry has further aggravated the risk factors, which arecontrolled by personnel. However, human beings themselves will be disturbed by extemal factors, such asstress, disease andother factors -all in all, depending on ”humanfactors”．
