Abstract
The utility model provides a split corrugated pipe ball valve. By using the split corrugated pipe ball valve, the problems that a spring between a valve seat and a valve body of the existing ball valve is easily affected by a high-temperature work environment, the performance of the existing ball valve is damaged, and the airtightness of the ball valve is affected are solved. The split corrugated pipe ball valve is characterized in that a corrugated pipe is also arranged on the outer side of a sealing seat ring; a sealing subassembly which can slide along the axial direction is arranged between the corrugated pipe and the sealing seat ring; and a sleeve is arranged between the corrugated pipe and a medium channel and is in sealing fit with the sealing seat ring, a left valve body and a right valve body. The split corrugated pipe ball valve has the advantages that a common spring is replaced by the corrugated pipe; and compared with the spring, the corrugated pipe can be used in a high temperature range, is suitable for a high-temperature working environment, has long service life, and is stable in performance.
Description
Technical field
The utility model relates to a kind of ball valve, is specifically related to a kind of to a point bellows ball valve.
Background technique
At present, along with the development of Chemical Industry, the production technology that water coal slurry pressure gasification is produced water gas is adopted in a large number.Not only there is high temperature, high pressure, inflammable, explosive gas medium and solid particle medium in the whole production process of this production technology, also requires whole deslagging, collection slag process to obey production routine control.
Chinese patent CN202451878U discloses a kind of separable type hard seal ball valve, this ball valve can be applied to the environment such as high temperature, high pressure, high corrosion, good sealing effect, Hookean spring circle is set between its valve seat and valve body especially, utilize the elasticity of spring to give valve seat certain seal preload, regulate spheroid, avoid stuck because expanding with heat and contract with cold, but owing to affected by working environment, spring Applicable temperature scope is little, its function easily changes with high temperature, thereby affects sealing, damages ball valve.
Model utility content
In order to overcome the deficiency of background technique, it is a kind of to a point bellows ball valve that the utility model provides, and the spring solving between valve seat and the valve body of existing ball valve is affected by the working environment of high temperature easily, thereby destroys its performance, affects the problem of sealing property of ball valves.
The technological scheme that the utility model adopts: one, to a point bellows ball valve, comprises left valve barrel, right valve barrel, spheroid, upper valve rod, lower valve rod, support, described left valve barrel and the docking mutually of right valve barrel left and right; Described support is arranged on left valve barrel and right valve barrel top; Described spheroid is arranged in left valve barrel and right valve barrel; Described upper valve rod is connected with spheroid top and bottom respectively with lower valve rod; Between described spheroid and left valve barrel and the inwall of right valve barrel, be equipped with seal holder ring; The outside of described seal holder ring is also provided with bellows, is provided with the black box of slippage vertically between described bellows and seal holder ring; Between described bellows and medium channel, be provided with one deck sleeve pipe, described sleeve pipe and seal holder ring, left valve barrel, right valve barrel are sealed and matched.
Described left valve barrel and right valve barrel arrange bellows place and are provided with steam blowing mouth.
Described left valve barrel is connected with nut by double threaded screw with right valve barrel bottom.
Described upper valve rod is provided with a circle boss by one end of spheroid, and described left valve barrel, right valve barrel are provided with the restraining groove suitable with boss.
The beneficial effects of the utility model are: adopt above scheme, bellows replaced to common spring, bellows compared with spring, its can be applicable temperature range higher, more can adapt to the working environment of high temperature, longer service life, performance is more stable.
Brief description of the drawings
