Abstract
The utility model provides an orbital ball valve. A valve base is a metal sealing valve base. The utility model is characterized in that an elastic groove (5) is arranged beside the sealing line (4) of the metal sealing valve base (2), and an O-shaped metal elastic ring (6) is arranged in the elastic groove (5). The orbital ball valve has the advantages of high temperature resistance and wear resistance.
Description
The utility model relates to a kind of track ball valve.
When the track ball valve was opened owing to ball valve, the ball stamen inclined earlier and turn to fully open position again behind valve seat, had avoided the sealing surface of seat scratch as ball valve, stopcock.Operational torque is little because of having, the reliable sealing characteristics are widely used in every field such as oil, chemical industry, generating, metallurgy for the track ball valve.But, common track ball valve can be divided into hard seal valve seat structure of full-metallic and nonmetal soft seal valve seat construction, the track ball valve of the hard seal valve seat structure of full-metallic, because its sealing surface does not have elasticity, when ball valve stamen and valve seat have the uneven wear ball valve just can produce leakage slightly, and the track ball valve of nonmetal soft seal valve seat construction, its nonmetallic material can not satisfy the operating conditions of high temperature media again.
The purpose of this utility model provides a kind of high temperature resistant, anti abrasive track ball valve.
To achieve these goals, technical solution of the present utility model is such: a kind of track ball valve, its valve seat are the metallic seal valve seat, and wherein the potted line of metallic seal valve seat is other is provided with the elasticity groove, and O type metallic elastic circle also is housed in the elasticity groove.
Because in the above-mentioned technical solution, the other elasticity groove that is provided with of the potted line of the metallic seal valve seat of track ball valve, also be provided with O type metallic elastic circle in the elasticity groove, the displacement that elasticity groove wherein makes the potted line on the valve seat can produce trace when the ball stamen cooperates pressurized, O type metallic elastic circle in the elasticity groove provides the better elastic effect to potted line, when the track ball valve is closed, ball valve stamen wedging valve seat and and potted line be adjacent to, be embedded in the elastic compensating that the O type metallic elastic circle in the metal seat valve provides, the potted line and the valve stamen sealing sphere of metal seat valve are tightly coincide, further improved the sealing reliability of track ball valve.And when track ball valve sealing face in use produces uneven wear, because the elastic compensating effect of O type eyelet, the track ball valve still can keep sealing reliably and not leak, therefore this track ball valve has the advantage of advantages of good abrasion, and foregoing all Sealings comprise that O type metallic elastic circle is all metallic material thereby this track ball valve and can works under high temperature, working condition such as inflammable.
Below in conjunction with drawings and Examples the utility model is described in further detail:
Fig. 1 is the structural drawing of the hard seal valve seat of full-metallic in the existing track ball valve.
Fig. 2 is the structural drawing of soft seal valve seat in the existing track ball valve.
The structural drawing of the valve seat of a kind of track ball valve that Fig. 3 provides for the utility model.
Fig. 4 is the partial enlarged drawing of Fig. 3.
Wherein: 1, ball stamen; 2, valve seat; 2-1, interior valve seat; 2-2, outer seat; 3, nonmetal seal valve seat; 4, potted line; 4-1, interior potted line; 4-2, external sealed line; 5, elasticity groove; 6, O type metallic elastic circle.
As the valve seat construction among Fig. 1 is the full-metallic hard sealing structure, and nonelastic compensation is just the potted line 4 on its ball stamen 1 and the valve seat 2 has the uneven wear ball valve to be easy to generate leakage slightly.
As the soft seal valve seat construction among Fig. 2, be combined with elastic compensating between its ball stamen 1 and the nonmetal seal valve seat 3, be difficult for producing and leak, but non-refractory.
And Fig. 3, the represented valve seat construction of Fig. 4 then processes elasticity grooves 5 on potted line 4 sides of metallic seal valve seat 2, and the O type metallic elastic circle 6 with favorable elasticity is housed in elasticity groove 5, when potted line 4 cooperatings on ball stamen 1 and the valve seat 2, because potted line 4 other being provided with are provided with O type metallic elastic circle 6 in elasticity groove 5 and the elasticity groove 5, make potted line 4 relative ball stamens 1 have the elastic compensating effect, when track ball valve sealing face produces uneven wear, elastic compensating effect by potted line 4, ball valve still can reliably seal, because of all Sealings noted earlier are metalwork, this kind track ball valve can be high temperature resistant in addition.
Fig. 3, track ball valve shown in Figure 4 is in order to make sealing effect better, and metallic seal valve seat 2 is designed to be combined by interior valve seat 2-1 and outer seat 2-2, elasticity groove 5 is surrounded by the outer ladder of interior valve seat 2-1 and the interior ladder of outer seat 2-2, the transverse section of elasticity groove 5 is the square shape that a breach is arranged, this breach is towards ball stamen 1, interior valve seat 2-1 is provided with external sealed line 4-2 near the position of elasticity groove 5 breach, outer seat 2-2 is provided with interior potted line 4-1 near the position of elasticity groove 5 breach, O type metallic elastic circle 6 is set in the elasticity groove 5, therefore resulting ball valve has two sealing lines 4, all but elastic compensating makes that its sealing is more reliable.If the potted line 4 of the foregoing valve seat 2 of this section is omitted one, only keep a sealing lines 4 and ball stamen 1 cooperating still can be realized the purpose of this utility model.
