Abstract
The utility model discloses a kind of stopcock, belong to valve technology field, comprise and revolve core in valve body and valve body, at valve outer wall, import and export to it from the middle part of valve body that two ends are extended stiffening rib; Described valve body is provided with corrosion allowance layer.The lumen at valve body pressure-bearing position is connected in aggregates with two ends runner, guarantee the Rigidity and strength of valve body, thus valve body does not burst when ensure that product normally uses, lumen at valve body pressure-bearing position and two ends runner are taked to increase corrosion allowance Rotating fields, make the actual wall thickness of valve higher than common standard requirement, improve corrosion fatigue life, product is reused, improves cost performance.
Description
Technical field
The utility model relates to valve technology field, in particular to a kind of stopcock.
Background technique
Stopcock revolves core as open-shut device with the plunger shape of band through hole, by revolving core to realize the valve of unlatching, closing motion and distribution media.The stopcock of chemical industry special operation condition mostly is the common Gland packing plug valve of choice for use, its structure is by the design of traditional standard method result of calculation, because of its reason such as material, structure, normally uses under can not ensureing, temperature difference operating mode greatly frequent in medium temperature change, valve body easily bursts, life-span is short, not easily accept by most chemical enterprise, simultaneously because of corrosion and the wearing and tearing of particle powder medium, sealing was easily lost efficacy, working life is short, can not reuse again, and the cost performance of product is poor.
Model utility content
The purpose of this utility model is to provide a kind of stopcock that can be applicable under chemical industry special operation condition, and to solve because medium temperature change is frequent when stopcock uses, the temperature difference is large, the problem that valve body easily bursts.
For realizing the utility model object, the technological scheme of employing is: a kind of stopcock, comprises revolving core in valve body and valve body, at valve outer wall, imports and exports that two ends are extended stiffening rib from the middle part of valve body to it; Described valve body is provided with corrosion allowance layer.
Namely by stiffening rib, the lumen at valve body pressure-bearing position is connected in aggregates with two ends runner, guarantee the Rigidity and strength of valve body, when ensure that product uses, valve body does not burst; Meanwhile, by corrosion allowance layer, valve body wall thick structure is controlled, add the actual wall thickness of valve body, improve corrosion fatigue life, meet the recycling demand of client.
Further, described stiffening rib is arranged in valve body bilateral symmetry.
Further, described stiffening rib is at the rectangular in cross-section in valve circulation passage direction.
Further, the outer wall in the middle part of described valve body and valve outer wall corresponding to two ends circulation passage arrange described corrosion allowance layer.
Further, the corrosion allowance layer of described valve body is suitable with the wall thickness of valve body.
The beneficial effects of the utility model:
One, reinforcing rib structure is set up at valve body pressure-bearing position, the lumen at valve body pressure-bearing position is connected in aggregates with two ends runner, guarantee the Rigidity and strength of valve body, thus valve body does not burst when ensure that product normally uses, and through manufacturing experimently and trying out, do not occur that like product when normal use, valve body occurs and bursts phenomenon etc., ensure that the safety reliability of this stopcock.
Two, the lumen at valve body pressure-bearing position and two ends runner are taked to increase corrosion allowance Rotating fields, it is suitable that its thickness is increased to the own thickness with valve body, make the actual wall thickness of valve higher than common standard requirement, improve corrosion fatigue life, product is reused, improve cost performance, reduce purchase cost.
Three, the structure of the utility model stopcock is simple, installation dimension is less, open and close rapidly, easy to operate, fluid resistance is little, is applicable to the liquid carried containing suspended matter and particle, the material containing crystalline solid can be carried after coordinating Insulation, be used for blocking, connecting media flow in pipeline, can be widely used in oilfield exploitation, conveying and refining equipment, be also widely used in oil, chemical industry, coal gas, rock gas, liquefied petroleum gas (LPG), HVAC industry and general industry simultaneously.
Accompanying drawing explanation
Fig. 1 is the half sectional view of the stopcock that the utility model provides;
Fig. 2 is the left view of valve body part in Fig. 1;
Fig. 3 is the plan view of valve body part in Fig. 1.
Embodiment
Also by reference to the accompanying drawings the utility model is described in further detail below by specific embodiment.
Fig. 1 to Fig. 3 shows the stopcock that the utility model provides, and comprises revolving core 2 in valve body 1 and valve body 1, at valve body 1 outer wall, imports and exports that two ends are extended stiffening rib 3 from the middle part of valve body 1 to it; Valve body 1 is provided with corrosion allowance layer 4.
Wherein valve body 1 is pressure part, plays pressure-bearing and connecting tube use, and revolving core 2 is open-shut device, forms the sealing that sealing pair realizes valve, revolve the keying that core 2 realizes valve with valve body 1.
Stiffening rib 3 is arranged in valve body 1 bilateral symmetry, is conducive to whole machine balancing stressed.Stiffening rib 3 is at the rectangular in cross-section in valve circulation passage direction.Outer wall in the middle part of valve body 1 and valve body 1 outer wall corresponding to two ends circulation passage arrange corrosion allowance layer 4, the outer wall of the lumen namely at valve body 1 pressure-bearing position and two ends runner adopts and arranges corrosion allowance layer 4 structure, make the thickness of corrosion allowance layer 4 suitable with valve body thickness, wall thickness that is concrete and circulation passage place is suitable, the actual wall thickness value of such valve is much larger than common design standard value, increase its corrosion fatigue life, product is reused.
This stopcock is through on probation, and do not occur that like product when normal use, valve body occurs and bursts phenomenon etc., its nominal pressure is 1.0 ~ 4.0MPa; Inside nominal diameter is 50 ~ 400mm; Applicable temperature is ﹣ 30 ~ 150 DEG C; Leak-down rate is by the regulation of GB/T 13927-2008.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
Claims (5)
