Description

A kind of exhaust gases passes bypass valve

Technical field

The utility model is related to fume treatment auxiliary more particularly to a kind of exhaust gases passes bypass valves.

Background technology

Other bypass flue is turned on and off by bypass valve, and traditional bypass valve sealing surface is close to the sealing of bypass flue Circle, realizes bypass flue sealing, and sealing surface is contacted with sealing ring sometimes by installing or sealing ring heat shrinkable is influenced, face contact meeting It has the gap, generates leakage, sealing effect is poor, and sealing ring failure easy to aging.

Utility model content

The applicant is directed to disadvantage mentioned above, has carried out Improvement, provides a kind of exhaust gases passes bypass valve.

Technical solution used by the utility model is as follows：

Guide rod, the guide rod is arranged in a kind of exhaust gases passes bypass valve, including bypass flue, the bypass flue outside Upper end connects cylinder block, and driving cylinder is connected on cylinder block, and the driving cylinder connects valve rod, and valve rod passes through cylinder block connection valve Plate, and the valve plate is worn on the guide bar, and sealing ring is set below valve plate, setting connection on the outside of the bypass flue upper end , connection ring is set on the connecting seat, soft sealing material, the sealing are set between the connection ring and bypass flue outer wall Ring can be inserted into soft sealing material.

The beneficial effects of the utility model are as follows：The exhaust gases passes bypass valve is inserted into soft sealing material by sealing ring, Increase sealing area, and soft sealing material is non-aging, ensures sealing effect.

Specific implementation mode

Below in conjunction with the accompanying drawings, illustrate specific embodiment of the present utility model.

As shown in Figure 1 to Figure 3, the exhaust gases passes bypass valve of the present embodiment, including bypass flue 1,1 outside of bypass flue are set Guide rod 2 is set, 2 upper end of guide rod connects cylinder block 3, and driving cylinder 4 is connected on cylinder block 3, and driving cylinder 4 connects valve rod 5, valve Bar 5 passes through cylinder block 3 to connect valve plate 6, and valve plate 6 is through on guide rod 2, and sealing ring 61, bypass flue is arranged in 6 lower section of valve plate Connecting seat 7 is set on the outside of 1 upper end, connection ring 71 is set on connecting seat 7, is arranged between 1 outer wall of connection ring 71 and bypass flue soft Property sealing material 8, sealing ring 61 can be inserted into soft sealing material 8.

The exhaust gases passes bypass valve is in use, by driving 4 actuatable valve plate 5 of cylinder along the up and down motion of guide rod 2, valve Plate 5, which moves downward, can be inserted into sealing ring 61 soft sealing material 8, while valve plate 5 is also pressed onto soft sealing material 8, by valve plate 5, Sealing ring 61 coordinates soft sealing material 8 to seal bypass flue 1, and valve plate 5, which moves upwards, can open bypass flue 1.

Above description is the explanation to the utility model, is not the restriction to utility model, defined by the utility model Range is referring to claim, and without prejudice to the basic structure of the utility model, the utility model can make any shape The modification of formula.
