Abstract
The invention discloses a V-shaped sealing ring which comprises a gland, an adjusting pad, a compression ring, V-shaped rings, a communicating hole and a support ring. The gland is connected with the compression ring, the compression ring is provided with a compression ring concave surface, the support ring is provided with a support ring convex surface, the V-shaped rings are mounted between the support ring convex surface and the compression ring concave surface, are compressed by the gland and are arranged in the same direction, and the adjusting pad is arranged between the gland and the compression ring. The V-shaped sealing ring has the advantages that the V-shaped sealing ring not only can be used for sealing the inner surfaces of cylinders, but also can be used for sealing the outer surfaces of shaft levers; pressure adjusting effects and V-shaped ring positioning effects can be realized by the compression ring; the V-shaped sealing ring is long in service life, and excellent sealing effects can be realized by the V-shaped sealing ring.
Description
Technical field
Field of sealing technology of the present invention, particularly relates to a kind of v-ring.
Background technique
In chemical reaction device, often need to connect reaction device, therefore the leakage sealing to prevent chemical reaction thing is needed, existing seal ring is most of adopts O shape circle, owing to being easily out of shape after O shape circle pressurized, and should have introducing angle and guide sleeve when installing, prevent O shape from enclosing by sharp edge institute's cut wound or scuffings such as sharp threads, working life is very short, and installing/dismounting complex operation, use is restricted.
Summary of the invention
The present invention, in order to overcome the deficiency of above-mentioned technical problem, provides a kind of v-ring, can solve the problems of the technologies described above completely.
The technological scheme solved the problems of the technologies described above is as follows:
A kind of v-ring, comprise gland, spacer, pressure ring, v shaped ring, intercommunicating pore and pushing out ring, described gland is connected with pressure ring, described pressure ring has pressure ring concave surface, and described pushing out ring has pushing out ring convex surface, and described v shaped ring is arranged between pushing out ring convex surface and pressure ring concave surface, and compress by gland, described v shaped ring is arranged in the same way, respectively with lip towards pressure direction, described gland and the joint of pressure ring are provided with spacer.
The compression face of v-ring is lip, and under pressure, easy and sealing surface fits tightly, and therefore has stronger self-tightening effect compared with O-ring seals.
Can according to different working pressures during use, several v shaped ring is overlapping, and overlapping number is more, and leakage rate is less, but quantity is too much, and the reduction of leakage rate is not remarkable, and surface friction drag sharply raises on the contrary, therefore generally selects 3 ~ 6.
Use after a period of time, when producing leakage due to the wearing and tearing of seal ring or distortion, the impacting force that can increase seal ring is eliminated.
The present invention both can seal the internal surface of cylinder, and such as piston seal also can seal the outer surface of axostylus axostyle, such as rod seal circle.V shaped ring and pressure ring, the complete installation of pushing out ring, and be arranged between pushing out ring convex surface and pressure ring concave surface, and compress with gland.When needing the inside and outside lip of v shaped ring to seal simultaneously, several intercommunicating pore should be offered on pushing out ring, make the pressure that acts on interior outer lip equal.Pressure ring plays a part to regulate pressure, also plays the role of positioning to v shaped ring simultaneously.Long service life of the present invention, good sealing effect.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is structural representation of the present invention;
Embodiment
A kind of v-ring as shown in Figure 1, comprise gland 1, spacer 2, pressure ring 3, v shaped ring 4, intercommunicating pore 5 and pushing out ring 6, described gland 1 is connected with pressure ring 3, described pressure ring 3 has pressure ring concave surface, described pushing out ring 6 has pushing out ring convex surface, and described v shaped ring 4 is arranged between pushing out ring convex surface and pressure ring concave surface, and compresses by gland 1, described v shaped ring 4 is arranged in the same way, and described gland 1 is provided with spacer 2 with the joint of pressure ring 3.Described v shaped ring is 4.Described v shaped ring also can be 3,5 and 6.Described pushing out ring 6 offers intercommunicating pore 5.
The present invention both can seal the internal surface of cylinder, and such as piston seal also can seal the outer surface of axostylus axostyle, such as rod seal circle.V shaped ring and pressure ring, the complete installation of pushing out ring, and be arranged between pushing out ring convex surface and pressure ring concave surface, and compress with gland.When needing the inside and outside lip of v shaped ring to seal simultaneously, several intercommunicating pore should be offered on pushing out ring, make the pressure that acts on interior outer lip equal.Pressure ring plays a part to regulate pressure, also plays the role of positioning to v shaped ring simultaneously.Long service life of the present invention, good sealing effect.
