Abstract
The utility model discloses a stainless steel ball valve. The stainless steel ball valve comprises a valve body, a bonnet and a valve core arranged inside the valve body, the valve body is connected with a first connecting pipe, the bonnet is connected with a second connecting pipe, and the top of the valve core is arranged in a pressure relief hole. According to the stainless steel ball valve, by means of a valve core structure with the pressure relief hole, large amounts of heat produced during a connecting process can be discharged quickly, and the manufacturing safety is guaranteed.
Description
Technical field
The utility model relates to a kind of ball valve, and valve body is stainless ball valve specifically.
Background technique
The pipeline that connects for its both sides of ball valve generally connects by nut or the threaded pipe of being located at the end at present, nut is fixed on valve one end end and also is movably connected in valve one end end, its valve body material mostly is ironcasting, the ball valve that is threaded under this kind cast iron structure for common fluid control be rub with the hands have a surplus but just not competent for corrosive liquid under some high pressure seepage often takes place in the threaded connection place and technological deficiency such as valve body corrosion occurs.Though existing adopt copper material as valve body material to adapt to the environment of contact corrosion gas such as refrigerant recovering industry, liquid, but the manufacture cost of copper is too high, be unfavorable for being extensive use of, how reduce manufacture cost, and possess the research object that corrosion resistance becomes those skilled in the art.
China's utility model patent patent No. 02232006.7 discloses a kind of loose joint valve, be to comprise that the wherein end internal thread screw thread structure that valve body is connected with pipeline changes system into the external thread wire buckle structure of forming loose joint with locknut and joint, valve is become one with loose joint.This technology does not propose the valve technical clarification that adaptability is used under high pressure corrosive liquid concrete conditions in the establishment of a specific crime.
Summary of the invention
The utility model provide a kind of simple in structure, make safely, be suitable for high pressure corrosive liquids or gas, particularly be suitable for the Stainless Steel Ball Valve of refrigerant recovering industry.
A kind of Stainless Steel Ball Valve comprises valve body and valve gap and is located at the interior spool of valve body that valve body and first is taken over and is connected, and valve gap and second is taken over and is connected, and relief hole is located at described spool top.This kind have relief hole valve core structure its mainly solved in being suitable for the Stainless Steel Ball Valve manufacture process of high pressure corrosive liquids or gas, valve body and first is taken over to be connected to be connected and all can be produced a large amount of heats (as heat of generation when being welded to connect) in the manufacture process, tend to the accident of blasting because valve body inner spool and valve body are the space of a sealing a large amount of heat accumulation like this, this also is that valve body is the technology cause with mostly adopting what be threaded being connected of adapter in the prior art.The utility model makes a large amount of heats that produce in connection procedure obtain rapid drainage by the valve core structure that has relief hole, has obtained to make the assurance of Security.
Be stainless steel material as the preferred valve body of structure, prevent that valve body is subjected to corrosive gas or stimulant liquid.
Described valve body and first is taken over soldering and is connected.Valve gap and second is taken over soldering and is connected.The Placement that this kind soldering connects is specially adapted to first adapter, second material of taking over this red copper character is stainless the connection with valve body, not only is connected firmly, and has the good pressure resistance energy
The connecting end that described valve body and first is taken over is provided with attachment hole, and attachment hole is pegged graft and first taken over, and is being welded to connect under the grafting because valve body and first is taken over, the leakage problem under high pressure corrosive liquids or the gas condition of also just having avoided being threaded.
The utility model makes a large amount of heats that produce in connection procedure obtain rapid drainage by the valve core structure that has relief hole, has obtained to make the assurance of Security.
Description of drawings

Embodiment
Referring to a kind of Stainless Steel Ball Valve of accompanying drawing 1 the utility model, comprise valve body 2 and valve gap 3 and be located at spool 5 in the valve body 2, valve body 2 and first is taken over 1 and is connected, and valve gap 3 and second adapter 4 are connected, relief hole 6 is located at spool 5 tops, prevents Stainless Steel Ball Valve the gathering of welding heat in manufacture process.
As the preferred valve body 2 of structure for stainless steel material by precision casting after cutting obtain, guaranteeing on the measuring body basis of valve body, prevent that valve body 2 is subjected to the erosion of corrosive gas or liquid.。
Taking over 1 soldering as preferred Placement valve body 2 and first is connected.Valve gap 3 and second is taken over 4 solderings and is connected.
Adopt the connecting end of valve body 2 and first adapter 1 to be provided with attachment hole in order to prevent that valve body 2 and first adapter 1 from leaking in the joint, attachment hole grafting first adapter 1 connects.
