Abstract
It the utility model is related to a kind of Thermal insulating ball valve, including valve body, valve seat, spheroid, valve rod, valve rod lower end uses square shaft to be connected with each other with spheroid upper end square hole, and being provided with the anti-of mutual cooperation between valve body in the middle part of valve rod gets step and airtight and watertight padding, and valve seat includes outlet side valve seat and inlet side valve seat；Mainly valve body uses integrated formed structure, sets insulation cladding between valve body imports and exports flange, incubation cavity is formed between the insulation cladding and valve outer surface, the steam joint of incubation cavity is communicated with insulation cladding；Valve outlet passage is formed with the sphere installation hole equal with valve pocket diameter, and outlet side valve seat is sealingly mounted in sphere installation hole by being screwed, its sealing ring and spheroid compression fit.Prevent cold environment lower valve in-vivo medium from freezing, there is the advantages that spheroid flexible rotation, valve opening and closing operation is reliable.
Description
Technical field
The utility model belongs to valve field, more particularly to a kind of ball valve.The utility model is applied to easy sharp freezing
Medium pipeline.
Background technology
It is widely used in medium pipeline control device ball valve is because of simple in construction, conveniently opening and closing, flow resistance is small.But cold
In cold environment on the medium pipeline of easy sharp freezing, medium in valve body easy freezing at low ambient temperatures, spheroid is caused not revolve
Turn, operation can not be opened and closed by valve is freezed to death.
The content of the invention
The purpose of this utility model is the problem of presence for prior art, there is provided one kind has valve body heat insulation function, prevents
Only body cavity medium low temperature environment freezes, and opens and closes operationally reliable Thermal insulating ball valve.
The technical solution of the utility model includes valve body, valve seat, spheroid, valve rod, and valve rod lower end is using on square shaft and spheroid
Hold square hole to be connected with each other, get step and airtight and watertight padding being provided with the anti-of mutual cooperation between valve body in the middle part of valve rod, valve seat includes
Outlet side valve seat and inlet side valve seat；Mainly valve body uses integrated formed structure, sets and protects between valve body imports and exports flange
Warm shell, incubation cavity is formed between the insulation cladding and valve outer surface, the steam joint of incubation cavity is communicated with insulation cladding；Valve body
Exit passageway is formed with the sphere installation hole equal with valve pocket diameter, and outlet side valve seat is sealingly mounted at sphere installation by being screwed
In hole, its sealing ring and spheroid compression fit.
The utility model has the advantages that an incubation cavity connected with high-temperature steam is set in the outer surface of integrative-structure valve body,
Prevent cold environment lower valve in-vivo medium from freezing, spheroid flexible rotation, valve opening and closing operation is reliably.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Thermal insulating ball valve as shown in Figure 1, including valve body 1, valve seat 4, spheroid 5, valve rod 6, the lower end of valve rod 6 use square shaft and ball
The upper end square hole of body 5 is connected with each other, and being provided with the anti-of mutual cooperation between the middle part of valve rod 6 and valve body 1 gets step and airtight and watertight padding, valve
Seat 4 includes outlet side valve seat and inlet side valve seat；Valve body 1 uses integrally casting shaping, can also use integral forging molding,
Valve body 1 sets insulation cladding 3 between importing and exporting flange, because valve body 1 is structure as a whole, insulation cladding 3 is welded on inlet and outlet
Between flange, insulation cladding 3 can also form insulation with 1 integral moulding by casting of valve body between the insulation cladding 3 and the outer surface of valve body 1
Chamber 7, the steam joint 2 of incubation cavity 7 is communicated with insulation cladding 3, high-temperature steam is injected in incubation cavity 7 by steam joint 2, is prevented
The only inner chamber medium sharp freezing of valve body 1；The exit passageway of valve body 1 is formed with the sphere installation hole equal with valve pocket diameter, and spheroid 5 is from ball
Body mounting hole loads in valve pocket to be connected with valve rod 6, and outlet side valve seat is sealingly mounted in sphere installation hole by being screwed, and its is close
Seal and the compression fit of spheroid 5, carbon seal ring is set between outlet side valve seat periphery and sphere installation hole inwall.
