Abstract
The utility model discloses a kind of chiller plant ball valve preventing bursting, comprise the ball valve that two ends are connected with adapter, ball valve comprises interconnective valve body and valve gap, the valve rod controlling ball valve opening and closing is provided with in valve body, described valve body and valve gap connecting end are provided with the annular boss of outwardly convex, annular boss external diameter is identical with valve gap external diameter, and the welding rod of all coated fusing after coagulation, welding rod cross section is circular arc cylindricality, circular arc cylindrical bottom is provided with two legs, a leg embeds valve body and valve gap joint, the coated annular boss side of another leg.The utility model, by arranging the annular boss of outwardly convex at valve body and valve gap connecting end, adds the wall thickness of valve body and valve gap connecting end, effectively prevent explosion problem.The cross section of welding rod forms two stand bar structure, clasping structure is formed for valve body and valve gap joint, prevents explosion further.
Description
Technical field
The utility model relates to a kind of ball valve, particularly relates to a kind of chiller plant ball valve preventing bursting.
Background technique
The ball valve used in current chiller plant, its needs bear larger pipeline pressure, often cause valve body and valve gap joint to occur technical problems such as bursting.Existing for valve body and valve gap joint occur bursting often adopt welding rod to weld mode to increase explosion-proof capabilities, but even if in actual use or some ball valves can be there are add welding rod, still there is Decrepitation Phenomena.A kind of thoroughly preventing how is provided to occur that the ball valve burst is the object that art technology people is badly in need of studying at valve body and valve gap joint.
The Chinese utility model patent patent No. 201220176096.3 discloses a kind of air-conditioning duct irony ball valve, comprise valve body and valve ball, valve body is made up of left adapter, right adapter and display pipe, together with left adapter is welded and fixed in display pipe and with display pipe with right adapter sleeve; Left adapter forms step in left adapter, left pad is placed on left adapter step, right adapter forms step in right adapter, right pad is placed on right adapter step, two limits of valve ball are pressed on left pad and right pad, valve rod is fixed on valve ball, and valve rod sleeve is on valve seat, and valve seat is fixed on display pipe.The technical clarification not in ball valve explosion etc. of this kind of ball valve or solution.
Summary of the invention
The utility model provides that a kind of structure is simple, the chiller plant ball valve preventing bursting of favorable sealing property.
A kind of chiller plant ball valve preventing bursting, comprise the ball valve that two ends are connected with adapter, ball valve comprises interconnective valve body and valve gap, the valve rod controlling ball valve opening and closing is provided with in valve body, described valve body and valve gap connecting end are provided with the annular boss of outwardly convex, annular boss external diameter is identical with valve gap external diameter, and the welding rod of all coated fusing after coagulation, welding rod cross section is circular arc cylindricality, circular arc cylindrical bottom is provided with two legs, a leg embeds valve body and valve gap joint, the coated annular boss side of another leg.This kind of ball-valve structure, by arranging the annular boss of outwardly convex at valve body and valve gap connecting end, adds the wall thickness of valve body and valve gap connecting end, effectively prevent explosion problem.The cross section of welding rod forms two stand bar structure, clasping structure is formed for valve body and valve gap joint, prevents explosion further.
Described welding rod periphery is provided with fold, and fold boxing bar periphery is uniformly distributed, and fold has compressed welding rod, improves the compactness of welding rod.
Described valve stem top periphery is provided with the bonnet of the valve body that is threaded.Pipe ends is provided with dust cap, and dust cap periphery is provided with annular protrusion, and the airtight connecting tubes of annular protrusion, prevents dust from entering ball valve, extends ball valve working life.
The utility model, by arranging the annular boss of outwardly convex at valve body and valve gap connecting end, adds the wall thickness of valve body and valve gap connecting end, effectively prevent explosion problem.The cross section of welding rod forms two stand bar structure, clasping structure is formed for valve body and valve gap joint, prevents explosion further.
