The design structure is improved, the welding process can be simplified, and the welding effect is more prominent.
Description
Technical field
The utility model belongs to valve technology field, and particularly, the utility model is particularly related to a kind of spherical ball valve that is welded and fixed.
Background technique
Welding ball valve is used all very extensive in every field, the quality that it is superior and high performance stability are that Normal Steel Casting ball valve is beyond one's reach.All-welded ball valve is far longer than cast steel ball valve working life, is widely used on the various pipes equipment such as gas, city heat supply, petrochemical industry, shipbuilding, iron and steel, voltage regulating station, power station.Welding ball valve can direct-burried in underground, need not build tall and big valve well, reduced engineering cost, also in the time of operated valve can being avoided, cause personnel's injury simultaneously, welding ball valve can move use reliably and with long-term, in the situation that valve normal running is used, reaches 20 years quality guarantee period.But the valve body structure design of current welding ball valve is reasonable not, manufacturing process and effect are slightly poor.
Summary of the invention
The purpose of this utility model is to provide a kind of spherical ball valve that is welded and fixed, the irrational problem of structural design existing to solve prior art.
In order to address the above problem, the utility model provides a kind of spherical ball valve that is welded and fixed, and its technological scheme is as follows:
A kind of spherical ball valve that is welded and fixed, comprise handle, valve rod, valve seat, spheroid, valve body, described valve body comprises side valve body and the middle valve body connecting as one, described spheroid and valve seat are arranged in described valve body, wherein, one end of described side valve body is welded in one end of described middle valve body, and the weld seam between described side valve body and described middle valve body is around the junction surface outer ring setting of described side valve body and described middle valve body.
Preferably, above-mentioned, be welded and fixed in spherical ball valve, the inner ring of described side valve body connecting end surface extends into the inner ring of described middle valve body connecting end surface, and described valve seat is located at the inner side surface of described side valve body connecting end surface.
Preferably, above-mentioned, be welded and fixed in spherical ball valve, the front side of described valve seat is provided with the seal ring of the PTFE material contacting with described spheroid, and the rear side of described valve seat is provided with the spring that embeds described valve body and drive described valve seat to move to described spheroid.
Preferably, above-mentioned, be welded and fixed in spherical ball valve, the lower end of described valve rod is provided with anti-leakage structure.
Preferably, above-mentioned, be welded and fixed in spherical ball valve, described valve rod adopts AISI303 stainless steel, and described valve body adopts AISI304 stainless steel.
The utility model, by improving project organization, can be simplified welding procedure, and be that welding effect is more outstanding.
Accompanying drawing explanation
Fig. 1 is the sectional structure schematic diagram of the utility model preferred embodiment.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
As shown in Figure 1, the utility model preferred embodiment mainly comprises handle 1, valve rod 2, valve seat 5, spheroid 4, valve body.
Wherein, valve body comprises side valve body 32 and the middle valve body 31 connecting as one, and spheroid 4 and valve seat 5 are arranged in the side valve body 31 of valve body.One end of side valve body 32 is welded in one end of middle valve body 31, and the weld seam 30 between side valve body 32 and middle valve body 31 is around the junction surface outer ring setting of side valve body 32 and middle valve body 32.Valve body structure Integral welded, does not have outside leakage phenomenon.
Preferably, the inner ring of side valve body 32 connecting end surfaces extends into the inner ring of middle valve body 31 connecting end surfaces, and valve seat 5 is located at the inner side surface of side valve body 31 connecting end surfaces.
Further preferably, in this preferred embodiment, valve seat 5 is comprised of PTFE seal ring 51 and spring 52, and seal ring 51 is positioned at the inner side of valve seat 5 and is close to spheroid 4 and arranges, and one end of spring 52 embeds in side valve body 32.The variation of seal ring 51 and 52 pairs of pressure and temperatures of spring is adaptable, in using scope, can not produce any leakage.
Valve body material is identical with pipe material, avoids occurring that stress is irregular, also can be due to earthquake and vehicle during through ground and extrusion-deformation.
Valve rod 2 adopts AISI303 stainless steel, and the side valve body 32 of valve body and middle valve body 31 adopt AISI304 stainless steel, through fine finishing, grind and make, and have excellent sealing performance and decay resistance.
This preferred embodiment can have welding, screw thread, flange etc. to select for user, to be connected with pipeline.The kind of drive can adopt handle, turbine, the drive mechanism such as pneumatic, electronic, and switch is light flexibly.
To sum up, the utility model compact structure, technique simple, lightweight, be easy to insulation, be convenient to mean level and install.Can be widely used in rock gas, oil, heat supply, chemical industry and the isometric defeated pipeline of thermoelectricity pipe network field.
As known by the technical knowledge, the utility model can be realized by other the embodiment that does not depart from its Spirit Essence or essential feature.Therefore, above-mentioned disclosed embodiment, with regard to each side, all just illustrates, and is not only.All changes within the scope of the utility model or within being equal to scope of the present utility model are all included in the utility model.
