Description
Technical field
The utility model relates to a kind of Wear-resistant, high-temperature resistant ball valve, belongs to water heating fittings technical field.
Background technique
Ball valve it there is the action of identical 90-degree rotation, be spheroid unlike faucet body, have manhole or passage by its axis.Ball valve is mainly used to make the flow direction cutting off, distribute and change medium in pipeline, and it is tight that it only needs to use the operation of 90-degree rotation and very little moment of rotation just can close.Ball valve optimum makees switch, cut-off valve uses.The main feature of ball valve is compact structure own, sealing is reliable, structure is simple, easy to maintenance, and sealing surface and sphere are everlasting closed state, not easily by medium erosion, be easy to Operation and maintenance, be applicable to the general work media such as water, solvent, acid and rock gas, but also be applicable to the severe medium of operating conditions, as oxygen, hydrogen peroxide, methane and ethene etc., be widely used in every profession and trade.Ball valve body can be overall, also can be knockdown.
Ball valve is primarily of formations such as valve body, valve seat, seal ring, spheroid, valve rod, filler, Glands.Seal ring, valve seat and filler are generally nonmetal, and follower is generally direct location, and the surface treatment of spheroid is wear-resisting chromium substantially, and the ball valve of this spline structure is often not ideal enough in wear-resisting, high temperature resistant.Seal ring and valve seat are directly combined with spheroid and rub, and non-metallic component is is easily worn and torn by the wearing layer of spheroid, the seal ring after being worn and produce gap between valve seat and spheroid just can seepage, and non-refractory; The design of valve rod is generally a valve rod be connected with spheroid top, in the easy off-axis of environment lower sphere of high pressure.
Summary of the invention
For solving the manufacture of above-mentioned two-way butterfly valve high-end designs, the utility model provides a kind of Wear-resistant, high-temperature resistant ball valve.
The technological scheme that the utility model adopts is: Wear-resistant, high-temperature resistant ball valve is by valve body, valve seat, spheroid, seal ring, upper valve rod, lower valve rod, follower is formed, valve body is the metal shell carrier of ball valve, valve seat is made up of left and right two pieces, be divided into surface of contact and stationary plane, surface of contact coincide with spheroid and contacts, stationary plane is connected with valve body, surface of contact there is seal groove, seal ring is installed in seal groove, valve seat is fastened on the left and right sides of spheroid, what adopt is the compound valve seat of metallic material and AC wear-resistant seal circle, the rubbing surface of spheroid and valve seat adopts HVOF technique spraying WC carbide high-abrasive material, the lower end of upper valve rod is connected to the top of spheroid, upper end can muff-coupling wrench or driving wheel, the shape of lower valve rod is inverted T shape, lower end connects valve body, upper end is connected to the below of spheroid, coordinate Wei Static between lower valve rod with spheroid, the two ends of follower are connected with valve body by adjusting screw, for adjustable follower.
The beneficial effects of the utility model are: the rubbing surface of spheroid adopts HVOF technique spraying WC carbide high-abrasive material, strengthens its surface abrasion resistance; Employing is the compound valve seat of metallic material and AC wear-resistant seal circle, and the alloy seal face of metal seat valve is when 400 ° of C high temperature, and seat material linear expansion coeffcient and spheroid linear expansion coeffcient, reach the sealing effect of valve; T-shaped lower valve rod and spheroid stationary fit, effectively ensure that the coaxality of lower valve rod, is conducive to the sealing of valve and the flexible of keying.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated:
Accompanying drawing 1 is lateral section of the present utility model structural representation;
In figure 1, valve body, 2, seal ring, 3, valve seat, 4, spheroid, 5, upper valve rod, 6, follower, 7, lower valve rod.
Embodiment
In the examples in the drawings, Wear-resistant, high-temperature resistant ball valve is by valve body 1, valve seat 3, spheroid 4, seal ring 2, upper valve rod 5, lower valve rod 7, follower 6 is formed, valve body 1 is the metal shell carrier of ball valve, valve seat 3 is made up of left and right two pieces, be divided into surface of contact and stationary plane, surface of contact coincide with spheroid 4 and contacts, stationary plane is connected with valve body 1, surface of contact there is seal groove, seal ring 2 is installed in seal groove, valve seat 3 is fastened on the left and right sides of spheroid 4, the lower end of upper valve rod 5 is connected to the top of spheroid 4, upper end can muff-coupling wrench or driving wheel, the shape of lower valve rod 7 is inverted T shape, lower end connects valve body 1, upper end is connected to the below of spheroid 4, the two ends of follower 6 are connected with valve body 1 by adjusting screw, for adjustable follower 6.
Embodiment 1: adopted by the rubbing surface of spheroid 4 and valve seat 3 HVOF technique to spray WC carbide high-abrasive material in advance, inlayed by AC abrasive sealing materials in the seal groove of valve seat 3, by after assembly technical requirement assembling the ball valve of Wear-resistant, high-temperature resistant.
Embodiment 2: Wear-resistant, high-temperature resistant ball valve of the present utility model, because the rubbing surface of the rubbing surface of spheroid 4 and valve seat 3 all adopts HVOF technique to spray WC carbide high-abrasive material, this high-abrasive material is alloy material, and the face of therefore spheroid 4 and valve seat 3 contact friction, has very strong wear-resisting property; What seal ring adopted is AC wear-resistant seal circle, and belong to high abrasion and resistant to elevated temperatures seal ring, valve working temperature is when 400 ° of C high temperature, and seat material linear expansion coeffcient and spheroid linear expansion coeffcient, ensure that the sealing effect of valve; T-shaped lower valve rod and spheroid stationary fit, effectively ensure that the coaxality of lower valve rod, is conducive to the sealing of valve and the flexible of keying.
