Abstract
The utility model discloses a seal regulating ball valve which belongs to the technical field of valves of a refrigeration system. The seal regulating ball valve comprises a valve seat, a valve body, a spherical valve core, a valve stem, a valve cap, a filling valve seat, a valve core and a filling valve cap, wherein the valve body is in threaded connection with the valve seat; the valve body and the valve seat are respectively externally connected with a valve body pipe interface and a valve seat pipe interface; the spherical valve core is located in the valve body; a seal gasket a and a seal gasket b are respectively arranged between the valve seat and the spherical valve core and between the valve body and the spherical valve core; the valve stem extends into the valve body and is fixedly connected with the spherical valve core; the valve cap is screwed on the valve body; the valve core is mounted in the filling valve seat; the charging valve cap is screwed on the filling valve seat; the valve seat and the valve body are sealed by welding; and the spherical valve core is provided with a through hole. The seal regulating ball valve adopting the structure can improve the external sealing effect and greatly reduce leakage in use, further can be used in environment with strong mechanical vibration, and is very convenient for regulating the valve stem during system operation.
Description
[technical field]
The utility model relates to a kind of sealed-regulating valve, especially relates to a kind of sealing that is applied in the refrigeration pipe system and regulates ball valve, belongs to the refrigeration system valve technology field.
[background technique]
Valve applications is extensive, and it is used for pipe-line system may command fluid medium pressure, flow and the flow direction, needs regular opening and closing, uses after a period of time, and sealability can descend to some extent.
Ball valve is regulated in the existing sealing that is used for refrigeration pipe system, and linkage structure generally is threaded between valve body and the valve seat, reaches the effect of outside seal even through the form of smearing anaerobic adhesive; Its internal structure reaches the effect of inner sealing through closely cooperating of spherical valve core and sealing gasket, and valve rod passes behind the valve body it and innerly is connected with spherical valve core, wherein; Ball valve is regulated in sealing and filled valve processes separately, and both the needs welding of processing back are connected, and cost is high; Efficient is low, be unfavorable for producing in enormous quantities, and sealing adjustment type ball valve in use; Can be because mechanical vibration cause the inefficacy that is threaded of valve body and valve seat, thus leakage caused.In addition, because valve body is connected the formed cavity in back with valve seat and there is pressure difference in spherical valve core, in system's running, cause valve rod to regulate inconvenience.
[model utility content]
The technical problem that the utility model will solve is that the deficiency that is directed against existing technology provides the sealing that a kind of sealability is more excellent, adjusting is convenient to regulate ball valve.
For solving the problems of the technologies described above, the utility model provides following technological scheme:
Ball valve is regulated in sealing, comprises valve seat, valve body, spherical valve core, valve rod, bonnet, fills valve seat, valve inside and filled bonnet, and valve body is threaded with valve seat; Valve body, valve seat be external valve body tube interface, valve seat interface tube respectively, and spherical valve core is positioned at valve body, between valve seat and the spherical valve core, be respectively equipped with sealing gasket a, sealing gasket b between valve body and the spherical valve core; Valve rod stretches in the valve body, and valve rod and spherical valve core be connected, and bonnet is rotatably connected on the valve body; Valve inside is loaded on and fills in the valve seat; Filled bonnet is rotatably connected in and fills on the valve seat, said valve seat and valve body welded seal, and said spherical valve core offers through hole.
As preferably, above-mentioned filled valve seat and valve body are structure as a whole.
After adopting this structure, avoid separately processing sealing to regulate ball valve, fill behind the valve again the failure welding that row brings when being welded to connect, leak, strengthened working life, and helped producing in batches such as weld porosity, valve body.
Regulate ball valve with the sealing of existing structure and compare, the utlity model has following beneficial effect:
1, valve seat is threaded the basis that assembling accomplishes with valve body on; Be about to the two welded seal again; Compare with smearing anaerobic adhesive, not only promoted the outside seal effect that ball valve is regulated in sealing, reduce the leakage problem in the using process significantly; Effectively practiced thrift cost, more can adapt under strong mechanical shock environment and use;
2, after spherical valve core was offered through hole, the inside and outside pressure of spherical valve core had obtained balance, and valve rod is regulated and become very convenient.
[description of drawings]
Do further explain below in conjunction with accompanying drawing with regard to the utility model.
Fig. 1 is the structure sectional view that ball valve is regulated in the utility model sealing;
Fig. 2 is the outline drawing of the utility model;
Fig. 3 is the left view of Fig. 2.
[embodiment]
Please refer to Fig. 1,2, shown in 3, seal and regulate ball valve, comprise valve seat 1, valve body 2, spherical valve core 3, valve rod 5, bonnet 51, fill valve seat 20, valve inside 7 and filled bonnet 200; Valve body 2 is threaded with valve seat 1, the respectively external valve body tube interface of valve body 2, valve seat 1 21, valve seat interface tube 11, and spherical valve core 3 is positioned at valve body 2; Between valve seat 1 and the spherical valve core 3, be respectively equipped with sealing gasket a41, sealing gasket b42 between valve body 2 and the spherical valve core 3, valve rod 5 stretches in the valve body 2, and valve rod 5 is connected with spherical valve core 3; Bonnet 51 is rotatably connected on the valve body 2, and valve inside 7 is loaded on and fills in the valve seat 20, fills bonnet 200 and is rotatably connected on the filled valve seat 20; After valve body 2 and valve seat 1 are threaded; The two argon arc welding manner is sealed, weld the back at both shown in the figure and form welded seal portion 9, spherical valve core 3 offers through hole 30.
Wherein, valve rod 5 has a groove 50, and after groove 50 was equiped with O-ring seals 6, valve rod 5 just cooperated with valve body 2.
As preferential mode of execution, fill valve seat 20 and be structure as a whole with valve body 2, adopt hot press-formed technology.
Through rotary valve rod 5, can adjust the folding degree of the inner through hole 8 of spherical valve core 3, be communicated with flow, the pressure of convenient accurately adjusting medium between control valve body interface tube 21 and the valve seat interface tube 11.After adjusting finishes, assembling valve inside 7 on filled valve seat 20, and the filled bonnet 200 of screwing on.
The above; It only is the preferred embodiment of the utility model; Be not to be the restriction of the utility model being made other form; Any professional and technical personnel of being familiar with should learn the structural change of under the enlightenment of the utility model, making, every with the utlity model has identical or close technological scheme, all still belong within the protection domain of the utility model.
