Utility model content is held:
The purpose of this utility model is to provide a kind of simple in construction, and processing capacity is few, dismounting and quick change combination valve A seating material transfer valve easy to assembly, maintenance cost is low.
The utility model is achieved like this:
The minimum interior circular diameter of valve gap 2 is more than the external diameter of valve plate 6, valve gap 2 is connected with valve body 1 bolt, the inner round wall bottom of valve gap has step to coordinate with the rank of falling from power of the right flank of the ring-shaped valve seats 4 that cross section is L-shaped, above and the left surface of ring-shaped valve seats coordinates with the chamfered groove of stack valve seat 5, the outside diameter of stack valve seat is identical with the maximum inscribed circle diameter of valve gap 2 with the maximum outside diameter of ring-shaped valve seats, the flange of medium conveying pipe 3 is positioned at the upper plane of stack valve seat 5 and contacts, the upper plane of stack valve seat is higher than the upper plane of valve gap 2, connecting bolt 7 is threadeded through the hole on the flange of medium conveying pipe or groove with the above of valve gap.
The minimum interior circular diameter of valve gap 2 is more than the external diameter of valve plate 6, valve gap 2 is connected with valve body 1 bolt, the inner round wall bottom of valve gap has step to coordinate with the step of stack valve seat 5, the flange of medium conveying pipe 3 is positioned at the upper plane of stack valve seat 5 and contacts, the upper plane of stack valve seat is threadeded with the above of valve gap through the hole on the flange of medium conveying pipe or groove higher than the upper plane of valve gap 2, connecting bolt 7.
Having groove to inlay with the ring-shaped valve seats 4 that cross section is rectangle below stack valve seat 5 to coordinate, ring-shaped valve seats 4 is made up of hard alloy or pottery.
Stack valve seat 5 is made up of whole hard alloy or pottery.
Valve plate 6 is flexibly connected with pivoted arm 8, and rotating shaft 9 is connected with pivoted arm 8, and the upper plane of the lower plane of ring-shaped valve seats 4, the lower plane of stack valve seat 5, the lower plane of valve gap 2 and valve plate 6 is at grade.
This utility model has the following advantages:
(1) valve gap 2 and stack valve seat 5 or ring-shaped valve seats 4 is spacing is connected, without connecting hole on stack valve seat 5, ring-shaped valve seats 4, stack valve seat 5 or the cylinder coordinated with the inwall of valve gap 2 with ring-shaped valve seats 4 composition, this cylinder is threadeded with valve gap 2 through the hole on medium conveying pipe 3 flange or groove by connecting bolt 7, thus it is clamped fixing, only need to pull down the connecting bolt 7 on medium conveying pipe flange 3 when changing valve seat, be not required to pull down whole valve gap 2.
(2) when valve plate 6 is changed, only need to be folded down the connecting bolt 7 on the flange of medium conveying pipe 3, stack valve seat 5, ring-shaped valve seats 4 can separate with medium conveying pipe and valve gap 2, and valve plate can conveniently take out replacing, and workload reduces half.
(3) stack valve seat, ring-shaped valve seats atresia, intensity is higher.
(4) dismountable valve seat, ring-shaped valve seats are very convenient, easy to maintenance, take a short time, can be greatly saved maintenance cost.
