Abstract
The utility model relates to a rubber seal ring of elastic seal butterfly valve. The side circumference of a circular ring shape rubber seal ring is provided with a stopping retrograded ring, the section shape of the circular ring shape rubber seal ring is two trapezoids with same lower bottom. In the two trapezoids with same lower bottom, the height of one trapezoid is four to five times of the height of the other trapezoid, the lower trapezoid is an arc upper bottom trapezoid whose upper bottom is an arc. The section provided with stopping retrograded ring is arranged at the two waists of the higher trapezoid. When being installed, the upper bottom of the higher trapezoid section of the rubber seal ring is inlayed into the combining groove on the butterfly plate or the valve body, and the lower trapezoid is a seal surface outside the groove. When the utility model is under the closing force or the medium pressure of the valve, the device matches with a ring groove which is arranged on the butterfly plate and the valve body to form seal along the circumference, which ensures that the seal at the installation part is reliable, with simple seal structure, convenient installation, after being installed, the installation external force can not affect the device, and the rubber seal ring is difficult to be destroyed, thus, the service life is long.
Description
Technical field
The utility model relates to a kind of rubber seal ring of elastic packing butterfly valve, particularly a kind of section configuration of rubber seal ring of elastic packing butterfly valve.
Background technique
Between the butterfly plate of elastic packing butterfly valve and valve body sealing pair is arranged, a Sealing is a metallic packing ring in the sealing pair, and another Sealing is a rubber seal ring.In the prior art, rubber seal ring is with the metal pressure ring rubber seal ring to be pressed on butterfly plate or the valve body, and the metal pressure ring is with being bolted on butterfly plate or the valve body of being uniformly distributed along the circumference.This rubber seal ring is owing to need just can be installed on butterfly plate or the valve body with the metal pressure ring, so sealing configuration is comparatively complicated, manufacturing expense is higher; Because the bolt that the metal pressure ring is a usefulness to be uniformly distributed along the circumference, trouble not only is installed, also can causes rubber seal ring to influence sealing along the circumference discontinuity, rubber seal ring is subjected to the effect of big like this fastening pressure for a long time, damage easily, influence the working life of elastic packing butterfly valve.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, proposes the rubber seal ring of long a kind of elastic packing butterfly valve in a kind of simple in structure, easy for installation, working life.
The utility model is realized with the following method.
The rubber seal ring of this elastic packing butterfly valve is the annular rubber seal ring, it is zigzag installation retaining ring that section is arranged on the side circumference of annular rubber seal ring, the section configuration of annular rubber seal ring is two isosceles trapezoids that have with going to the bottom, with in two isosceles trapezoids of going to the bottom, trapezoidal height is that another is trapezoidal high four～five times, lower trapezoidal be that the circular arc upper base is trapezoidal, the trapezoidal upper base of circular arc upper base is a circular arc, and it is on higher two trapezoidal waists that retaining ring section zigzag fashion is installed.
When using the utility model, need on butterfly plate or valve body, to process the circular groove that section configuration matches with higher trapezoidal section configuration, there is locking trough the side of circular groove, during installation the upper base of the high trapezoidal section of rubber seal ring is got final product towards the notch embedding, low trapezoidal outside groove, the toroidal surface at low trapezoidal circular arc upper base place is a sealing surface, installs in the locking trough of side that the retaining ring is embedded in circular groove, prevents that this rubber seal ring from withdrawing from groove at valve opening with when closing.The utility model is when power of closing that is subjected to valve or pressure medium, can with butterfly plate on or the circular groove inwall that matches on the valve body form sealing along circumference, the sealing that guarantees the installation position is reliable, sealing configuration is simple, easy for installation, the utility model is mounted in the mating groove on the butterfly plate or on the valve body, and the effect of external force is not installed after the installation, rubber seal ring is not fragile, and working life is longer.
Below in conjunction with accompanying drawing, the utility model is further described.
Description of drawings
Fig. 1 is that the master of the rubber seal ring of this elastic packing butterfly valve looks schematic representation;
Fig. 2 is the A-A cross-sectional schematic of Fig. 1;
Fig. 3 be mounted in rubber seal ring in the mating groove on the butterfly plate or on the valve body generalized section.
Embodiment
Among Fig. 1, Fig. 2, the rubber seal ring of this elastic packing butterfly valve has annular rubber seal ring 1, there are twice that retaining ring 2,3 is installed on the side circumference of annular rubber seal ring, the section configuration of annular rubber seal ring is two trapezoidal 4,5 that have with going to the bottom, during same two of going to the bottom are trapezoidal, trapezoidal 5 height is trapezoidal 4 high four～five times, lower trapezoidal 4 is that the circular arc upper base is trapezoidal, the trapezoidal upper base of circular arc upper base is a circular arc 6, and the section zigzag fashion 7,8 that the retaining ring is installed is on higher two trapezoidal waists.
The higher trapezoidal upper base of above-mentioned rubber seal ring section is a circular arc, and the higher trapezoidal upper base of rubber seal ring section also can be a straight line.
The sealing surface of above-mentioned rubber seal ring is used to be installed in valve body towards the outside of rubber seal ring.The sealing surface of rubber seal ring also can be used to be installed in butterfly plate towards the inboard of rubber seal ring.
Installation retaining ring on the circumference of above-mentioned rubber seal ring side also can have only together.
Among Fig. 3, the rubber seal ring of this elastic packing butterfly valve is installed in 9 li of mating grooves on the butterfly plate or on the valve body, and in order more to help sealing, the bottom land of mating groove and rubber seal interannular can have certain interval 10.
