Abstract
The utility model discloses an adjustable joint ball valve, comprising a valve body (1), a valve seat (2), a valve ball (3), a valve rod (4), a valve cover (5), a fixation joint (6) and an outer screw cap (7) arranged on one end of the valve body (1), characterized in that: another end of the valve body is provided with an active connection tube (8); a pressure screw cap (9) and a connection screw cap (10) form a telescopic tube device; the inner end of the active connection tube (8) is telescopically inserted into the inner cavity of the valve body (1), the pressure screw cap (9) is screwed with the valve body and presses the active connection tube (8) into the valve body and a clamping ring (15) is arranged on the outer wall at the outer end of the active connection tube (8) and the connection screw cap (10) is sleeved on the outer end of the active connection tube (8). The advantages of the adjustable joint ball valve are that: the active connection tube (8) is telescopically inserted into the valve body (1) to prolong or shorten the valve body, so as to conquer the defects that the span of the tube interface is over long or over short and the ball valve is very conveniently mounted.
Description
Technical field:
The utility model relates to a kind of fluid valve, relates in particular to be used for the ball valve of pipelines such as plumbing, oil, gas, specifically is a kind of adjustable joint ball valve.
Background technique:
In the pipeline of actual life and industrial plumbing, oil, gas, all many valves can be installed, to reach unlatching, close or to regulate the purpose of its switch degree.Existing ball valve all is an integral type, and is when the mounting ball valve of pipeline centre that ball valve two-port and front and back two pipe interfaces is identical relative, is connected and fixed with a silk mouthful nut then.This mode that is connected and fixed, installation brings very big difficulty to pipeline, the one, because of the length of its ball valve body is a fixed number, when the span of pipe interface excessive or too small, the ball valve two-port can not be coincide with pipeline front and back two interfaces docks, cause ball valve not installed, bring very big difficulty to the installer; If ball valve is installed, must extend pipe or kill pipes match the span of its pipe interface and the length of ball valve body; The 2nd, after ball valve installs or after using a period of time,, in the time of changing or keep in repair ball valve, be difficult to the ball valve that finds valve body length consistent with the pipe interface span in case ball valve damages, bring very big trouble and inconvenience to the maintenance work of pipeline.
The model utility content:
The technical problems to be solved in the utility model is that the problem and shortage at above-mentioned prior art exists provides a kind of adjustable joint ball valve.When being installed in this ball valve in the pipeline, needn't too emphasize the validity of pipe interface span, remedy the long or too short deficiency of pipe interface span at mounting ball valve place by the adjustability of ball valve itself; Can easily ball valve be installed, simultaneously, later replacing or maintenance also can easily be carried out quickly.
Technical solution of the present utility model is:
Adjustable joint ball valve, comprise valve body, valve seat, valve ball, valve rod, valve gap, one end of valve body is provided with a permanent joint and external nut, it is characterized in that, the other end of valve body is provided with the telescopic pipe device, described telescopic pipe device is by active an adapter, a clamping nut and a coupling nut are formed, be plugged in the body cavity the inner scalability of active adapter, clamping nut is screwed onto on the valve body and with the activity adapter and is pressed in the valve body, the active outer wall of taking over the outer end is provided with a snap ring, and coupling nut is enclosed within the active outer end of taking over.
Compared with prior art, the utlity model has following advantage: the end at valve body is provided with the telescopic pipe device, the activity of telescopic pipe device is plugged in the valve body with taking over scalability, because its scalability, valve body freely can be prolonged or shortens, remedy the long or too short deficiency of pipe interface span with this, the span of its pipe interface and the length of ball valve body are matched; Therefore, can easily ball valve be installed, simultaneously, provide great convenience the replacing or the maintenance of later pipeline ball valve.
The utility model also has following feature and advantage:
The described active external diameter of taking over equals the internal diameter of described valve body.This structure can make active the adapter be connected compactlyer and proper with the valve body intermittence.
Description of drawings:
Accompanying drawing is the structural representation of the adjustable joint ball valve of the utility model.
Shown in the figure: 1, valve body, 2, valve seat, 3, valve ball, 4, valve rod, 5, valve gap, 6, permanent joint, 7, external nut, 8, the active adapter, 9, clamping nut, 10, coupling nut, 11, handle, 12, retainer ring, 13, plain washer, 14, O type circle, 15, snap ring.
Embodiment:
Below in conjunction with the drawings and specific embodiments the adjustable joint ball valve of the utility model is described further:
Shown in the accompanying drawing, adjustable joint ball valve, comprise valve body 1, valve seat 2, valve ball 3, valve rod 4, valve gap 5, one end of valve body 1 is provided with a permanent joint 6 and external nut 7, be connected with an operating grip 11 on the valve rod 4, it is characterized in that, the other end of valve body 1 is provided with the telescopic pipe device, described telescopic pipe device is by an active adapter 8, a clamping nut 9 and a coupling nut 10 are formed, the external diameter of active adapter 8 equals the internal diameter of described valve body 1, be plugged in valve body 1 inner chamber, clamping nut 9 is screwed onto on the valve body 1 and with active joint 8 and is pressed in the valve body 1 active adapter 8 inner scalabilities, is provided with retainer ring 12 between clamping nut 9 and valve body 1 and the active adapter 8, plain washer 13 and O type circle 14, the active outer wall of taking over 8 outer ends is provided with a snap ring 15, and coupling nut 10 is enclosed within active 8 outer ends of taking over.
During installation, the external nut 7 of an end that earlier ball valve is equipped with permanent joint is screwed on the pipe of pipe interface one end, the activity that then the ball valve body the other end is equipped with is taken over 8 inner insertions in the valve body 1, the end face of the outer end of active adapter 8 is just in time aligned with the pipe end face of the pipe interface the other end is identical, to screw on the pipe of coupling nut 10 on the pipe interface again, then, clamping nut is tightened on the valve body and activity taken over and be pressed in the valve body.Like this, ball valve just is installed on the pipe interface very like a cork, and is faster and better, easily laborsaving.
