Abstract
The invention provides a novel material and technology suitable for a clamp type butterfly valve body. The novel clamp type butterfly valve is characterized in that a seamless steel tube after cutting is subjected to groove processing by a machine tool according to standards, then a valve body and a valve neck are welded to form the novel clamp type butterfly valve, and a traditionally used valve body casted by ductile cast iron is replaced. The firefighting clamp type butterfly valve is also called a firefighting groove butterfly valve or a groove type (clamp) connecting valve and has the advantages as follows: the mounting is rapid, simple, safe and reliable and is not limited by a mounting field, maintenance of a pipeline and the valve is facilitated, vibration isolation and sound isolation effects are realized, variance generated by non-coaxiality of pipeline connection is overcome in certain angle range, problems of heat expansion and cold contraction caused by temperature difference are solved and the like; the novel clamp type butterfly valve is widely applied to fluid conveying pipelines of pipeline projects such as water supply and drainage, firefighting, air conditioners, gas, petroleum, chemical industry, water treatment, municipal administration, shipbuilding and the like and is used for controlling the fluid.
Description
Technical field
The invention belongs to valve technology field, especially relates to a kind of novel clip butterfly valve.
Background technology
Traditional clip butterfly valve body mainly adopts casting valve body, although more selection flexibly can be had on material, from gray iron, but magnesium iron is to ordinary carbon steel owing to casting the feature of itself, casting flaw is pore such as, burning into sand, and shrinkage cavity/pine limits the pressure-bearing grade of casting valve, allowance is big, and yield rate is relatively low.Be just that precision castings also has casting flaw: as molding shrinkage hole, trachoma divide, shape face, plug hole.Size aspect does not limit too much.
The material of ductile iron pipe is spheroidal graphite cast-iron, and due to its production technology, producing foundry goods needs a large amount of foundry goods workmans, and environment is also made certain pollution.
For this reason, it may be necessary to a kind of novel clip butterfly valve solves these problems.
Summary of the invention
The problem that the invention to solve is many defects of traditional clip butterfly valve body, such as casting flaw such as pore, burning into sand, and shrinkage cavity/pine limits the pressure-bearing grade of casting valve, and allowance is big, and yield rate is relatively low..
For solving above-mentioned technical problem, the invention employed technical scheme comprise that a kind of novel clip butterfly valve of offer, a kind of clip butterfly valve body that is applicable to is by after seamless steel pipe cutting, groove is processed according to standard through lathe, valve body and valve neck are welded, instead of conventionally used spheroidal graphite cast-iron casting valve body.The invention has the advantage that and has the advantages that the PN25 that its compressive resistance is risen by original cast iron valve body PN16, when experimental pressure reaches PN25, has no any seepage.And the material of ductile iron pipe is spheroidal graphite cast-iron, due to its production technology, produce foundry goods and need a large amount of foundry goods workmans, environment is also made certain pollution, contrast uses mechanical stitch to squeeze the seamless steel pipe pulled out, and the latter is more energy efficient, environmental protection, saves a large amount of manpower, alleviate the advantages such as enterprise's recruitment difficulty, therefore occur in that cost price surpasses in reverse phenomenon.Following table is two kinds of tubing market price contrasts, it is seen that after adopting valve body, not only properties of product have very big lifting, also more according to advantage in price.

Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the invention is elaborated.
The one that the invention embodiment provides is applicable to clip butterfly valve body Novel seamless steel tube material,.After the cleaved machine of seamless steel pipe cuts according to valve specification, then valve body, the welding of valve neck is carried out then through lathe polish, polishing, its force-bearing situation, valve body performance have the features such as firm, tolerance is strong, solve the husky hole of husky casting cast iron valve body appearance simultaneously, bear the shortcomings such as pressure is low, cost of manufacture is high..Utilizing the valve body that the embodiment of the present invention provides, metal streamline is complete, it is ensured that part has good mechanical property and long service life, be all foundry goods incomparable.
Above an embodiment of the invention is described in detail, but described content has been only the preferred embodiment of the invention, it is impossible to be considered the practical range for limiting the invention.All equalizations made according to the invention application range change and improvement etc., all should still belong within the patent covering scope of the invention.
