Abstract
The utility model relates to a ball valve used in a pipeline of a refrigeration system. The ball valve comprises a valve body, a valve core, a valve seat, a valve cap of the ball valve, a valve stem, a rotating mechanism, O rings, copper connecting pipes and a hexagonal cap, wherein the valve core is positioned in the valve body, the valve seat is positioned between the valve body and the valve core, the valve cap of the ball valve is used for fixing the valve core and the valve seat in the valve body, the valve stem is inserted on the valve core, the rotating mechanism is positioned at the upper end of the valve stem, two O rings are arranged at the lower end of the valve stem, the valve stem is sheathed by the hexagonal cap which is connected on the valve body, the copper connecting pipes are connected at the two ends of the valve body, and the ball valve is characterized in that the rotating mechanism comprises a pin bar and a stop block, the pin bar is inserted on the valve stem, and the stop block is arranged at the upper end of the valve body. The ball valve disclosed by the utility model has the advantages of simple design, convenience in use and clear switch indication of the valve, and can save operation time of working staff and improve working efficiency.
Description
Technical field
The utility model relates to a kind of for the ducted ball valve of refrigeration system.
Background technique
The ducted ball valve of refrigeration system is a kind of fluid control member, and the application of valve more and more widely and requires also more and more higher.The existing ball valve that mainly is used in the SPLIT AIR-CONDITIONING SYSTEM, its play connect and to refrigerant by effects such as, conductings.At present, China produces small-sized valve, and technology content is not high, and based on manual poor efficiency valve.When using ball valve, during the ball valve switch that has indication indeterminate, cause switch not in place, system is unclear and coherent; The valve that has then is bad switch, does not have the thing of switch knob and so on, and each switch all needs the instrument of spanner and so on, and troublesome poeration is lost time, and increases workload.
Summary of the invention
In order to address the above problem, the utility model provides a kind of ball valve, and the switch indication is clear and definite, easy to operate, saves time, and has improved working efficiency.
Technical solution scheme of the present invention is: a kind of ball valve, it comprises valve body, spool, valve seat, the ball valve bonnet, valve rod, rotating machinery, " O " type circle, copper connecting tube and hexagonal nuts, spool is positioned at valve inner, valve seat is between valve body and spool, the ball valve bonnet is fixed on spool and valve seat in the valve body, valve rod is inserted on the spool, rotating machinery is positioned at the valve rod upper end, there is twice " O " type circle the valve rod lower end, and hexagonal nuts is enclosed within the valve rod outside, is connected on the valve body, copper connecting tube is connected the valve body two ends, it is characterized in that described rotating machinery comprises pin rod and stop block, the pin rod is inserted on the valve rod, and stop block is in the valve body upper end.
Described copper connecting tube spout diameter is 6.5mm-54.1mm, and the ball valve height is 49mm-136.5mm, ball valve length 138mm-305mm, ball valve width 27.8mm-92mm.
In the described hexagonal nuts screw thread is arranged, it also is screw thread that valve body top contacts with hexagonal nuts, and hexagonal nuts is enclosed within the valve rod outside, is tightened on the valve body.
Described copper connecting tube and valve body, copper connecting tube and bonnet have screw thread between bonnet and the valve body, use the argon arc welding welding fabrication after being threaded again.
This simplicity of design of the present utility model, easy to use, the threshold switch indication is clear and definite, saves staff's operating time, has improved working efficiency.
Description of drawings
Fig. 1 is the sectional view of ball valve side view.
Fig. 2 is the schematic representation of ball valve.
Embodiment
, describe below in conjunction with figure the utility model implementation for further:
As shown in Figure 1, a kind of ball valve, it comprises valve body 1, spool 2, valve seat 3, ball valve bonnet 4, valve rod 5, pin rod 6, " O " type circle 7, copper connecting tube 8, hexagonal nuts 9 and stop block 10, spool 2 is positioned at valve body 1 inside, valve seat 3 is between valve body 1 and spool 2, ball valve bonnet 4 is fixed on spool and valve seat 3 in the valve body 1, valve rod 5 is inserted on the spool 2, valve rod 5 upper ends laterally are inserted with pin rod 6, and there is twice " O " type circle 7 valve rod 5 lower ends, and hexagonal nuts 9 is enclosed within valve rod 5 outsides, be connected on the valve body 1, copper connecting tube 8 is connected valve body 1 two ends, and stop block 10 is positioned at valve body 1 upper end, with pin rod 6 on same horizontal plane.
Rotating dog rod 6 closes or opens from closing to from reaching when the utility model is used in operation, and according to the indication of stop block 10, the pin rod has only 90 ° angle of swing, is easy to easy manipulation.
The utility model is applicable to uses such as refrigerator, refrigeration equipment.
