Test Equipment for Ball valve DN15-100

DN15-100球閥試驗臺 （數(shù)顯全自動型）

1.   Test principle檢測原理

Ball valve is tested for:球閥進(jìn)行如下檢測 

a.    Pressure test with AIR inside 24 bar. Duration 30 sec after pressure reach 24 bar.

強(qiáng)度檢測：24 bar。保壓時間：30秒。 

b.    Leakage test with AIR inside 6 bar. From left to right. Duration 30 sec no bubbles.

右密封試驗：6 bar。保壓時間：30秒。 

c.    Leakage test with AIR inside 6 bar. From right to left. Duration 30 sec no bubbles.

左密封試驗：6 bar。保壓時間：30秒。 

2.   Observation觀察

a.    Pressure test with AIR inside 24 bar.

a. 24 bar 強(qiáng)度檢測 

Valve is open. Test equipment door or cover must be closed (without closing door not allowed start testing).

Water pump should fill the water in the open chamber. In parallel fill AIR pressure 24 bar inside the valve. All together should take not more than 30 sec. After stabilisation follow 15 sec visual inspection.

打開被測閥門，設(shè)備門必須為關(guān)閉狀態(tài)（門開啟時，不允許進(jìn)行檢測），24 bar氣壓上升時，水泵也必須開啟向容腔內(nèi)注水， 以上兩者必須在30秒內(nèi)完成，然后目測15秒。

b.    Leakage test with AIR inside 6 bar. From left to right.

b.    6 bar 右密封檢測 

       Valve is closed. Test door is open.

Fill in Air pressure from left side 6 bar. Slowly open valve in order to see bubbles on small observation glass with water. After that close the valve and wait until valve stop leaking. In 30 second observe leakage, no bubbles in 30 sec.

關(guān)閉被測閥門，打開設(shè)備門。將6bar的氣體從左端進(jìn)入通入到被測閥門的腔體內(nèi)，慢慢地打開被測閥門并觀察玻璃容器內(nèi)地氣泡，然后關(guān)閉被測閥門直到無泄漏時，30秒內(nèi)無氣泡為合格品。 

c.    Leakage test with AIR inside 6 bar. Repeat procedure of testing from right to left.

c.從右向左，重復(fù)以上動作，檢測左密封 

3.   Equipment features設(shè)備概述

Water chamber should be from stainless steel.

盛水容腔為不銹鋼制作。 

Door window should be made out of hardened glass in order to protect worker in case of leakage and broken valve.

觀察門上需安裝有鋼化玻璃，保護(hù)操作者，防止被測地泄漏和破裂。 

Each side should be equipped with precise manometers 0-60 bar D100 mm.

必須安裝有兩只60bar D100mm的精確壓力表。 

Valve fixture on one side should be fixed and another movable in order to cover length of valves from DN15-100.

 被測閥門在安裝時必須保證一端固定，另一端可移動，以適合DN15-100的閥門的結(jié)構(gòu)長度的需要。

Valve tightening fixture is special for each DN and should be easily replaceable.

被測的每種規(guī)格閥門的緊固件必須保證輕松可拆換性。 

For each Valve DN should be make special seat in order to position valve in the centre of fixture.

每種被測閥門必須有專用支架以保證對中安裝。 

Valve should be tighten with O ring rubber with max. 25% compression.

閥門的密封需通過“O”型密封圈實現(xiàn)，密封圈最大壓縮量不允許超過25％。 

固定被測閥門的力必須經(jīng)過計算，需滿足24bar DN100的閥門要求。頂緊需用氣缸來實現(xiàn)。
