Abstract
The utility model discloses a formula of relying on oneself low temperature governing valve comprises valve body and bellows balanced type executor, and characterized by is at the valve body install long connecting pipe between valve body and the valve gap additional, add in the periphery of valve body and bellows balanced type executor and establish the section of thick bamboo that keeps warm, regulating spring, bellows case subassembly and bellows piston assembly all adopt austenite stainless steel material producing, the built -in cotton insulation material that rockfills of the section of thick bamboo that keeps warm, the link of valve body and pipeline is a butt welding formula structure, and this product is in that the low temperature environment condition is still can the working property reliable and stable, the regulation control is sensitive, has effectively expanded the application scope of self -operated pressure control valve product.
Description
Technical field
The utility model relates to a kind of self-contained pressure regulator, particularly relates to a kind of self-powering type low temperature modulating valve.
Background technique
Because of the normally used self-contained pressure regulator of prior art, its final controlling element mainly adopts convolution diaphragm or cylinder piston two kinds of structural types, its load performance, anti-dielectric corrosion performance are not all fine, be generally only applicable to normal temperature, non-aggressive medium occasion uses.To lower than-30 DEG C of low temperature and the stronger mixture condition of corrosivity, need by the improvement to pressure balancing structure pattern, stuffing box packing position insulation isolation structure, and set up the technological means such as external insulation device, improve the applicability that direct-operated regulator keeps well-tuned control effects under worst cold case.
Summary of the invention
For the deficiency that prior art exists, the purpose of this utility model is: provide a kind of, self-powering type low temperature modulating valve that regulable control sensitive stable and reliable for performance at cold environmental conditions endure.
Technical solution of the present utility model is: a kind of self-powering type low temperature modulating valve, and be made up of valve body and bellows balanced type final controlling element, valve body is by valve body
,valve seat, Bellows valves core assembly, long connecting tube, press table, heat-preservation cylinder, adjustment disk, Regulation spring, column, valve gap, stuffing box packing, Gland, spring seat, top board and link assemble, bellows balanced type final controlling element is assembled by cylinder block, push rod, bellows piston assembly and link, it is characterized in that installing long connecting tube additional between the described valve body and valve gap of valve body, add heat-preservation cylinder in the periphery of valve body and bellows balanced type final controlling element.
As preferentially, described Regulation spring, Bellows valves core assembly and bellows piston assembly all adopt austenitic stainless steel material to make.
As preferentially, described heat-preservation cylinder is made up of cone, cylindrical shell and upper cover, cone lower end and long connecting tube lower flange, all uses fixing bolt fastening between upper cover and cylindrical shell.
As preferentially, in described heat-preservation cylinder, be filled with asbestos thermal insulating material.
As preferentially, described heat-preservation cylinder adopts austenitic stainless steel material to make.
As preferentially, the connecting end of described valve body and pipeline is butt joint type structure.
The beneficial effect that the utility model brings is:
1, because having installed long connecting tube between valve body and valve gap additional, reducing stuffing box packing by cryogenic media effect, can effectively avoid the low temperature seal of stuffing box packing to lose efficacy.
2, Regulation spring, Bellows valves core assembly and bellows piston assembly all adopt austenitic stainless steel material to make, compare carbon steel because of Austenitic Stainless Steel and there is excellent low-temperature flexibility, effectively can expand the applicable cryogenic temperature scope that can ensure that valve normally works.
3, because having added heat-preservation cylinder in the periphery of valve body and bellows balanced type final controlling element, at the in-built cotton thermal insulating material that rockfills of heat-preservation cylinder, the vaporization of cryogenic media can be isolated better, ensureing that valve continuing under worst cold case normally works.
4, valve body and pipeline adopt butt joint type to be connected, and can avoid easily occurring the risk that medium leaks outside ensure that production safety better when adopting flange connection type.
