Abstract
The utility model relates to a kind of pair and diffuses plastic valve, be provided with valve body, described valve body two ends are respectively equipped with end pipe, spool chamber, valve-rod cavity is provided with in described valve body, spherical spool is provided with in described spool chamber, described spool is outside equipped with valve seat, described valve seat is provided with valve seat insert, described spool is connected with a valve rod, multilayer valve stem packing ring is set in described valve-rod cavity, described valve stem tip is provided with operation cap, and described valve-rod cavity is provided with operation cap seal ring in outside, described end pipe is provided with exhaust stack joint.The utility model is applicable to natural gas valve, has the advantage that sealing is high, acidproof, alkaline-resisting, the life-span long, reduce maintenance rate, improve manufacturing efficiency.
Description
Technical field
The utility model belongs to a kind of valve, particularly a kind of Plastic valve of rock gas.
Background technique
Pipeline valve has a variety of, and often kind of valve manufacture material is all mainly divided into Normal Steel Casting, alloyed steel, non-ferrous metal, PE polythene plastics etc.Existing PE valve mainly ball seal mode, adopt spheroid face sealing means, 10 cun of required precisions are higher, plastic sphere difficulty of processing is quite large, especially big-and-middle-sized valve is produced, and spheroid outside adopts rubber gasket, rubber gasket exist aging, the shortcoming such as to pull, reduce the whole service life of valve to a certain extent.
Along with the development of science and technology, PE plastics steel wire is strengthened, Mild Steel Expanded Sheets strengthens the appearance of tubing and the application of electric melting pipe fittings product in natural-gas transfer pipeline, to valve in the duct answer 15 with proposing higher requirement in working life.Traditional steel, alloyed steel valve in use 3-5 at most, short, 1-2 just scraps renewal because of reasons such as corrosions, and the life-span is short, far can not reach the standard that PE steel wire tubing uses ISUZU company.Though non-ferrous metal valve increases working life, non-ferrous metal value is expensive.
Model utility content
The purpose of this utility model is to solve the problem, and proposes a kind of pair and diffuses plastic valve, and this pair is diffused plastic valve and have the advantages that sealing is high, acidproof, alkaline-resisting, the life-span long, reduce maintenance rate, improve manufacturing efficiency.
The purpose of this utility model is achieved through the following technical solutions: twoly diffuse plastic valve, be provided with valve body, it is characterized in that: described valve body two ends are respectively equipped with end pipe, spool chamber is provided with in described valve body, valve-rod cavity, spherical spool is provided with in described spool chamber, described spool is outside equipped with valve seat, described valve seat is provided with valve seat insert, described spool is connected with a valve rod, multilayer valve stem packing ring is set in described valve-rod cavity, described valve stem tip is provided with operation cap, described valve-rod cavity is provided with operation cap seal ring in outside, described end pipe is provided with exhaust stack joint, the sleeve of one lengthening is set outside described valve-rod cavity, described operation cap connects an operating stem lengthened, described operating stem arranges an operation knob on top.
Described exhaust stack joint adds the pipeline being connected to a lengthening, and the end of described pipeline is provided with the valve of rotatable unlatching.
Described sleeve is provided with fixing frame.
When the utility model valve is connected with pipeline, uses electric melting pipe fittings welding machine to the energising of winding the two poles of the earth, with electric current, low carbon steel heating wire is generated heat, fusing PE pipeline valve contacts dough model material with PE plastic tube, makes valve and pipeline carry out fusion and welds.Of the present utility modelly to be also advantageous in that:
1, the working life of valve is increased, can be identical with the pipeline life-span;
2, reduce difficulty of construction, improve efficiency of construction, save installation cost, reduce rate of fault;
3, decrease composed component, also relatively can reduce the space of Fa Men Bowl in pipeline;
4, sealing is more thorough, and difficulty of processing is low, is more suitable for big-and-middle-sized valve and produces, uses.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is internal structure schematic diagram of the present utility model;
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment: see accompanying drawing 1, 2, twoly diffuse plastic valve, be provided with valve body 1, described valve body two ends are respectively equipped with end pipe 2, spool chamber is provided with in described valve body, valve-rod cavity, spherical spool 3 is provided with in described spool chamber, described spool is outside equipped with valve seat 4, described valve seat is provided with valve seat insert 5, described spool is connected with a valve rod 6, multilayer valve stem packing ring 7 is set in described valve-rod cavity, described valve stem tip is provided with operation cap 9, described valve-rod cavity is provided with operation cap seal ring 8 in outside, described end pipe is provided with exhaust stack joint 10, the sleeve 11 of one lengthening is set outside described valve-rod cavity, described operation cap connects an operating stem 12 lengthened, described operating stem arranges an operation knob 13 on top, described exhaust stack joint adds the pipeline 14 being connected to a lengthening, and the end of described pipeline is provided with the valve 15 of rotatable unlatching, described sleeve is provided with fixing frame 16.
Last it is noted that obviously, above-described embodiment is only for the utility model example is clearly described, and the restriction not to mode of execution.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all mode of executions.And thus the apparent change of extending out or variation be still among protection domain of the present utility model.
