Description
Technical field
This utility model relates to a kind of fluid control valve, particularly to a kind of modified model Double-active-joint ball valve.
Background technology
Ball valve is mainly used to flowing and the closedown of liquid in control piper, and some physics of monitoring fluid in pipeline
Parameter, it has only to the operation with 90-degree rotation and the least rotating torque just can be closed tight.Typically switch or stop valve
Using, be characterized in that fluid resistance is little, switch is convenient, is widely used in civil area and central air-conditioning, heating installation, oil, change
In the industrial circles such as work.The most traditional ball valve and the connecting portion of pipe fitting are fixed, thus give and ball valve etc.
Valve and other pipe fittings connect installation and cause certain limitation.
Known ball valve is mainly made up of valve body, ball valve core, valve rod and turning handle, and described valve body is provided with vertically and manages
The water inlet end of part connection and water side, described water inlet end is provided with the female thread being connected with pipe fitting or external screw thread, institute with water side
Stating that ball valve core is rotating to be arranged in valve body between water inlet end and water side, this ball valve core is provided with the stream of through medium
Body latus rectum, one end of described valve rod is connected through valve body upper side wall with ball valve core, and the freedom of valve rod is located at by described turning handle
Play on end and open ball valve core or close the effect of ball valve core, according to the existing fixed female thread of ball valve connected mode even
Connecing, its installation effectiveness is low, and more difficult dismounting does not has again filtering function, is easily reduced the service life of valve, it is necessary to separately pacify
Fixed filter, increases the most again construction labor intensity, and pipeline connection increases easily leakage, increases cost to user, to raising
Economic benefit is unfavorable, and in the actual application of existing market, advocates Fast Installation when valve is arranged on pipeline in a large number, convenient, flexible
Dismounting, has again filtering function, can reduce again cost.
Chinese Patent Application No. disclosed in also having at present: " the loose joint knot of a kind of valve and pipe fitting of 201020283745.0
Structure ", particular content is: also include attaching nut (2) and the spherical movable joint being made up of a bulb (31) and interface portion (32)
(3), the outer end of described attaching nut's internal face is provided with dogging shoulder (21), and the bulb of described spherical movable joint is installed on attaching nut's
