Abstract
A soft seal valve core for a valve solves the problems that a current valve core is low in fabrication efficiency and high in cost. The soft seal valve core comprises a valve core body and a soft sealing layer covered on the surface of the valve core body which is a nylon fiber valve core or a nylon resin valve core.
Description
Technical field
The utility model relates to a kind of spool, particularly a kind of valve soft sealing valve core.
Background technique
Valve is widely used on the pipeline of draining, has to regulate and throttling function, and lifting or switching by spool reach the purpose of opening or closing.At present, the spool of gate valve mostly is Iron And Steel Casting, and its casting technique comprises: at first, need first molded core, utilize core to manufacture pattern; Then, reach the moulding spool by the casting molten steel, and after moulding, core can't utilize again, can only become waste product and abandon, cause environmental pollution, in addition in the time of the moulding core, due to weather effect, easily form bubble when humidity of the air is high and cause Durchgangshohle, affect product qualified rate.Moreover complicated by the manufacturing process of steel casting spool, workman's intensity is large, and major part is to adopt electric furnace to smelt iron water, the iron and steel fusing point is high, cause that energy consumption is high, after the steel casting moulding cool time long, make whole work efficiency low.
The model utility content
The utility model proposes a kind of valve soft sealing valve core, solved existing valve spool of valve and made that efficient is low, the high in cost of production problem.
The technical solution of the utility model is achieved in that
A kind of valve soft sealing valve core comprises spool body and the soft seal layer that is covered in the spool body surface, and described spool body is nylon fiber spool or nylon resin spool.
Preferential, described soft seal layer is rubber layer.
Preferential, described nylon fiber spool is nylon glass fiber spool.
Nylon fiber spool of the present utility model comprises nylon material and lamination coating.
A kind of production method of valve soft sealing valve core comprises the following steps:
At first, the configuration raw material mix nylon material and lamination coating according to certain proportion, adjust the proportioning of nylon and lamination coating, and proportion of fibrous material is larger, and the product strength of output is higher;
Then, with being equipped with the method for raw material employing ejaculation, die cavity and extrusion modling, obtain the spool body;
At last, cover the rubber material layer at the spool body surface.
By above-mentioned to description of the present utility model as can be known, compared to the prior art, the utlity model has following advantage:
The spool of this valve adopts the nylon fiber material to make, have the advantages such as energy-conserving and environment-protective, processing technology is simple, manufacturing efficiency is high, yield rate is high, labor strength is low, and glass fibre to have intensity high, by add glass fibre in nylon, make the intensity of product high, not yielding.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or description of the Prior Art, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Accompanying drawing 1 is main TV structure schematic diagram of the present utility model.
Accompanying drawing 2 is the part sectional structure schematic diagram of overlooking of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
See figures.1.and.2, a kind of valve soft sealing valve core comprises spool body 1 and the soft seal layer 2 that is covered in spool body 1 surface, and described spool body 1 is nylon fiber spool or nylon resin spool.Described soft seal layer 2 is rubber layer.
Nylon fiber spool of the present utility model comprises nylon material and lamination coating.Described lamination coating preferred glass fibers.
Valve soft sealing valve core of the present utility model comprises soft sealing gate valve, fire hydrant spool, buckle butterfly valve plate and silk mouthful valve spool of valve etc.
Valve soft sealing valve core manufacturing process of the present utility model is as follows:
At first, the configuration raw material mix nylon material and lamination coating according to certain proportion, adjust the proportioning of nylon and lamination coating, and proportion of fibrous material is larger, and the product strength of output is higher;
Then, with being equipped with the method for raw material employing ejaculation, die cavity and extrusion modling, obtain the spool body;
At last, cover the rubber material layer at the spool body surface.
Compared to the prior art, the utlity model has following advantage:
The spool of this valve adopts the nylon fiber material to make, have the advantages such as energy-conserving and environment-protective, processing technology is simple, manufacturing efficiency is high, yield rate is high, labor strength is low, and glass fibre to have intensity high, by add glass fibre in nylon, make the intensity of product high, not yielding.
The above is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
