Loose joint valve is mainly used in blocking or connecting medium, also can be used for the regulating and control of fluid, is widely used in chemical industry, long-distance transport pipes, papermaking, power industry.The material mainly copper or PP plastics of loose joint valve, the loose joint valve that PP plastics are made has the advantages such as light weight, hydrophily are low, good heat resistance, but PP plastics winter hardiness is poor, easily oxidized after using a period of time, and with changing, loose joint valve operation is more loaded down with trivial details, impact is produced and life, therefore need to provide a kind of good heat insulating, the loose joint valve of long service life.
Model utility content
Goal of the invention: provide a kind of and use that cold tolerance is good, the loose joint valve of long service life.
Technological scheme: loose joint valve, comprise valve body, handle, valve rod, spheroid, sealing seat, it is characterized in that, described valve rod is connected with valve body, described handle is connected with one end of valve rod, the both sides of described valve body are respectively equipped with valve port, described valve port is provided with screw thread, be connected with valve port by screw thread by order, described valve rod and valve body joint are provided with valve rod O ring, described spheroid and valve body joint are provided with ball pad, ball pad is provided with ball pad O ring, described sealing seat and valve body joint are provided with sealing seat O ring, described by order with valve port joint be provided with body O ring, described valve rod O ring, ball pad O ring, sealing seat O ring, the wire diameter of body O ring is oval wire diameter.Oval wire diameter is as the seal ring of plane sealing, and such seal ring is arranged in seal groove and oppresses through long-time, and enough surplus seal rings also can be had to play seal action.
As preferably of the present utility model, the ratio of described elliptical line footpath long axis length and minor axis length is 1.3 ~ 2:1, and the ratio of preferred elliptical line footpath long axis length and minor axis length is 1.5 ~ 1.6:1.
As preferably of the present utility model; the inwall of described valve body (1) is provided with nano-antibacterial layer; although PP plastics itself have certain anti-corrosion function; but long-time practical still meeting breed bacteria or accumulation incrustation scale; thus affect water quality; effectively can reduce bacteria breed after increasing nano-antibacterial layer, protection water quality is not secondary polluted, and extends the service time of valve.
As preferably of the present utility model, described valve port, the screw thread connected by order scribble nano-antibacterial layer, owing to often can be disassembled by making, also have bacteria breed in unloading process, can organize the growth of screw thread place bacterium after increasing antibiotic layer.
As preferably of the present utility model, described handle is provided with antiskid thread.
As preferably of the present utility model, be provided with anti-aging layer outside described valve body, anti-aging layer effectively can keep out ultraviolet, and loose joint valve surface can be prevented by weathering.
As preferably of the present utility model, outside described anti-aging layer, be provided with flame-retardant layer.
As preferably of the present utility model, the thickness of described nano-antibacterial layer is 50 ~ 75 μm.
As preferably of the present utility model, the thickness of described anti-aging layer is 15 ~ 35 μm.
As preferably of the present utility model, the thickness of described flame-retardant layer is 10 ~ 20 μm.
Beneficial effect:
1, the utility model provides a kind of loose joint valve, and the wire diameter of the valve rod O ring of this loose joint valve, ball pad O ring, sealing seat O ring, body O ring is oval wire diameter.Oval wire diameter is as the seal ring of plane sealing, and such seal ring is arranged in seal groove and oppresses through long-time, and enough surplus seal rings also can be had to play seal action.
2, scribble nano-antibacterial layer at the inwall of the utility model loose joint valve and threaded coupling place, can bacteria breed be prevented, keep duct cleaning.
3, scribble anti-aging layer and flame-retardant layer in the outside of the utility model loose joint valve body, effectively can extend the working life of loose joint valve.
Accompanying drawing explanation
The overall schematic of Fig. 1 the utility model loose joint invention.
