Description
Technical field
The utility model relates to a kind of modulating valve, be specifically related to a kind of heavy caliber cage type regulating valve.
Background technique
Current cage type regulating valve kind is on the market a lot, but most using effect is not good, there is following defect: during use, noise is comparatively large, heavier-weight, and sealing effect is not good, and precision is low, and bring some inconvenience to the use of people, practicability is not strong.
Model utility content
For the deficiency that prior art exists, the utility model object is to provide a kind of heavy caliber cage type regulating valve, compact structure, lightweight, noise is low, the suitable High Pressure Difference fluid controlling various temperature, is applicable to allow that amount of leakage is very little, pressure reduction is larger before and after valve occasion.
To achieve these goals, the utility model realizes by the following technical solutions: a kind of heavy caliber cage type regulating valve, comprise valve body, first Graphite pad, cage valve, spool, guide sleeve, second Graphite pad, valve gap, valve rod, metal gasket, graphite packing, bolt and Gland, in valve body, the first Graphite pad is provided with cage valve, cage valve matches with spool, spool and valve rod joint are socketed with guide sleeve, valve body is fixed with valve gap by the second Graphite pad and bolt, valve gap and cooperation place, valve rod top are provided with metal gasket, graphite packing, valve gap top is fixedly connected with Gland by bolt.
As preferably, described valve body is provided with gas source interface, gas source interface is connected with pressure controller and source of the gas.
As preferably, described valve inner runner is S-type.
As preferably, described spool is single seat guidance type spool.
The beneficial effects of the utility model: compact structure, lightweight, noise is low, the suitable High Pressure Difference fluid controlling various temperature, is applicable to allow that amount of leakage is very little, pressure reduction is larger before and after valve occasion.
Accompanying drawing explanation
The utility model is described in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is structural representation of the present utility model.
Embodiment
The technological means realized for making the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the utility model further.
With reference to Fig. 1, this embodiment by the following technical solutions: a kind of heavy caliber cage type regulating valve.Comprise valve body 1, first Graphite pad 2, cage valve 3, spool 4, guide sleeve 5, second Graphite pad 6, valve gap 7, valve rod 8, metal gasket 9, graphite packing 10, bolt 11 and Gland 12, in valve body 1, first Graphite pad 2 is provided with cage valve 3, cage valve 3 matches with spool 4, spool 4 and valve rod 8 joint are socketed with guide sleeve 5, valve body 1 is fixed with valve gap 7 by the second Graphite pad 6 and bolt, valve gap 7 and cooperation place, valve rod 8 top are provided with metal gasket 9, graphite packing 10, and valve gap 7 top is fixedly connected with Gland 12 by bolt 11.
It should be noted that and described valve body 1 is provided with gas source interface, gas source interface is connected with pressure controller and source of the gas.
It should be noted that described valve body 1 inner flow passage is S-type.
In addition, described spool 4 is single seat guidance type spool.
This embodiment mainly utilizes the pressure of fluid to realize the quick acting of spool, and steering force is little, and adopts single seat to seal, traffic characteristic curve precision is high, compact structure, lightweight, be active in one's movements, droop loss is little, valve capacity is large, and noise is low, easy to maintenance, the suitable High Pressure Difference fluid controlling various temperature, is applicable to allow that amount of leakage is very little, pressure reduction is larger before and after valve occasion.
More than show and describe basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
