Abstract
A bi-directional metal seal regulation ball valve mainly resolves the problems that the current ball valve has poor seal and cannot accurately regulate magnitude of discharge. The utility model is characterized in that: a groove that is arranged at the lower part of the corresponding surface of a left valve body and a right valve body (1, 2) is inlayed with a locating ring (4); a valve ball (5) whose two sides are radically and correspondingly provided with a wedged groove (8) is clamped in the locating ring (4) and between to valve seats (3); the outer ends of the two valve seats (3) are respectively provided with a butterfly spring (6) that contacts to a adjusting sleeve (7). The utility model has the advantages of regulating magnitude of discharge and good sealing effect.
Description
Technical field:
The utility model relates to the used valve in oil field oil extraction transportation field, and especially bidirectional metal sealing is regulated ball valve.
Background technique:
Valve is widely used in each department of national economy, it is a kind of universal machine product that has a large capacity and a wide range, it is mounted in valve in the various piping system, be used to control pressure, flow and the flow direction etc. of pipeline medium, because the difference of pressure, temperature, flow, physical property and the chemical property of medium, and the control requirement of system and usage requirement is different, so of a great variety.Ball valve then is wherein a kind of, and present existing ball valve owing to only have through hole on the valve ball in the valve, so just can not accurately be regulated the size of flow, influence ordinary production, on the other hand, sealing seat is fixed in the valve body, when sealing seat during because of distortion or corrosion and damage, make valve seal not tight, cause medium waste in the pipeline, have potential safety hazard, befouling environment.
The model utility content:
Can not accurately regulate the deficiency of flow size, sealing effect difference in order to overcome existing ball valve, the utility model provides a kind of bidirectional metal sealing to regulate ball valve, and this bidirectional metal sealing adjusting ball valve has can regulate the flow size, the characteristics of good sealing effect.
The technical solution of the utility model is: this bidirectional metal sealing is regulated ball valve and is comprised left and right sides valve body and valve seat, left and right sides valve body links into an integrated entity by screw, be inlaid with positioning ring in the groove that valve body corresponding surface lower end, the left and right sides has, clamping has the radially corresponding valve ball that has wedge-shaped impression in two ends in the positioning ring and between two valve seats, and the outer end of two valve seats is equipped with respectively and adjusts the belleville spring that cover touches mutually.
The beneficial effect that the utlity model has is: be inlaid with positioning ring because bidirectional metal sealing is regulated ball valve in the groove that valve body corresponding surface lower end, the left and right sides has, make and form a cavity between valve ball and the valve body, reduce the friction between the valve ball valve seat, guarantee the sealing of valve, clamping has the radially corresponding valve ball that has wedge-shaped impression in two ends in the positioning ring and between two valve seats, during by the rotation valve ball, because of the groove on the valve ball is a wedge shape, so width is arranged, when import and export were aimed at wide place, it is big that the flow in the pipeline just becomes, when the narrow place of groove aligning is imported and exported, flow in the pipeline just diminishes, and so just can regulate the size of flow.Touched belleville spring mutually in two valve seat outer ends, touched the adjustment cover the belleville spring foreign minister, when the prooving of valve seat, can come automatic regulating valve seat by belleville spring, guarantee that valve seat is in tight the contact all the time with valve ball, when the prooving of valve seat is serious, can adjust the elastic force of spring by adjusting cover, sealing is strengthened, improved sealing effect, guarantee that valve seat closely contacts with valve ball, reduce maintenance load, improved manufacturing efficiency.
Description of drawings:
Accompanying drawing 1 is the utility model structure sectional view.
1-left valve barrel among the figure, the 2-right valve barrel, the 3-valve seat, the 4-positioning ring, the 5-valve ball, the 6-spring, 7-adjusts cover, the 8-groove.
Embodiment:
Below in conjunction with accompanying drawing will the utility model is described in further detail:
By shown in Figure 1, this bidirectional metal sealing is regulated ball valve and is comprised left and right sides valve body (1,2) and valve seat 3, left and right sides valve body (1,2) link into an integrated entity by screw, the groove that left and right sides valve body (1,2) corresponding surface lower end has is inlaid with positioning ring 4 in the groove, make valve ball 5 and valve body (1,2) form a cavity between, reduce the friction between valve ball 5 and valve body (1,2) and the valve seat 3; Clamping has valve ball 5 in the positioning ring 4 and between two valve seats 3, the radially corresponding wedge-shaped impression 8 that has in valve ball 5 two ends, in rotation during valve ball 5, because of the groove on the valve ball 58 in different size, so the flow by valve ball 5 does not just wait, and so just reaches the purpose of regulating flow; The outer end of two valve seats 3 is equipped with respectively and adjusts cover 7 belleville springs that touch mutually 6, one end of belleville spring 6 touches mutually with valve seat 3 simultaneously, produce under the situation of wearing and tearing at valve seat 3, spring 6 closely leans on valve seat 3 and valve ball 5 by elastic force, strengthen sealability, spring 6 can be adjusted cover 7 by rotation and regulate the elastic force size, makes spring 6 that enough resiliency urged valve seats 3 be arranged, and keeps the sealing of valve seat 3 and valve ball 5.
