Abstract
The utility model discloses a valve of an automatic catalyst feeder. The valve comprises a valve body, a valve stem and a valve plate. The valve stem is connected with a cylinder, sealing packing is arranged at the upper end of the valve stem, a butterfly spring is arranged between the sealing packing and the top of the valve stem and is arranged in a pressurization cavity, and the pressurization cavity is connected with an inflation inlet. The problem of gas leakage of a valve stem of an existing valve of an automatic catalyst feeder can be solved by the aid of the valve, and the valve has the advantages of simple structure, durability and convenience in maintenance and replacement.
Description
Technical field
The utility model relates to a kind of automatic catalyst feeder valve, particularly carries hardness
High a kind of automatic catalyst feeder valve.
Background technique
Current domestic oil refinery catalyzer charging system cut-off valve ubiquity is not wear-resisting, the problem that life-span is short, in order to address this problem, many trials have been done by relevant producer, valve kind used is numerous, comprise membrane valve, ball valve, three eccentric ball valves, common ceramic double gate valve etc., from using effect, all undesirable, to give normal production, safeguard and bring very large adverse effect, valve is in use for some time, valve rod and filler are because friction, produce gap, thereby make valve packing wearing and tearing, catalyzer is from outwards a large amount of leakages of valve packing.
Model utility content
Its object of the utility model is just to provide a kind of automatic catalyst feeder valve, has solved the problem of the valve rod gas leakage of existing automatic catalyst feeder valve existence, has feature simple in structure, durable in use, convenient maintenance and replacement.
The technological scheme that realizes above-mentioned purpose and take, comprises valve body, valve rod, valve plate, and valve rod connects cylinder, described valve rod upper end is provided with stuffing box packing, between stuffing box packing and valve stem tip, be provided with butterfly spring, described butterfly spring is arranged in booster cavity, and booster cavity connects inflation inlet.
Compared with prior art the utlity model has following advantage.
Owing to being provided with butterfly spring and booster cavity between valve and cylinder connection, thereby can effectively overcome valve in use for some time, valve rod and filler are because friction, produce gap, thereby make valve packing wearing and tearing, the problems that catalyzer outwards leaks in a large number from valve packing, have feature simple in structure, durable in use, convenient maintenance and replacement.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is this apparatus structure schematic diagram.
Embodiment
This device comprises valve body 1, valve rod 2, valve plate 3, and valve rod 2 connects cylinder 8, as shown in Figure 1, described valve rod 2 upper ends are provided with stuffing box packing 4, between stuffing box packing 4 and valve rod 2 tops, be provided with butterfly spring 5, described butterfly spring 5 is arranged in booster cavity 6, and booster cavity 6 connects inflation inlet 7.
This device comprises valve body 1, valve rod 2, valve plate 3, stuffing box packing 4, butterfly spring 5, booster cavity 6, inflation inlet 7, cylinder 8, utilizes butterfly spring (or spring) pretightening force, the valve of booster cavity pressure to filler and valve lever clearance self repair.
In use, 5 pairs of fillers of butterfly spring 4 produce pretightening force, valve rod 2 and the fricative gap of filler 4 are repaired automatically, and inflation inlet 7 is filled with gas, and pressure is greater than pressure medium in valve, when butterfly spring 5 pretightening forces are not enough, be filled with gas and also can stop medium in valve to leak outside, after improvement, valve can be applied in automatic catalyst feeder system for a long time, reduce maintenance cost and workman's intensity, guarantee normal need of production.
