Description
Technical Field
The utility model relates to the field of machinery, in particular to a novel water pump gland.
Background
The water pump gland sets up the lid at water pump tip promptly for with the sealed of water pump, wherein the water pump during operation, it will bear inside water pressure, consequently to its sealing performance and the structural strength requirement of connecting higher. The existing sealing structure is that an elastic sealing ring is usually arranged at the contact position of a water pump gland and a water pump main body. But has a problem in that its sealing performance is largely different from the pressure provided by the bolt when it is installed. And the water pump vibrates easily and leads to the bolt not hard up during operation for the pressure that provides is not enough, thereby influences its leakproofness.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a novel gland for a water pump. The utility model ensures the sealing performance, effectively prevents water leakage at the gland, increases the strength of the gland and prolongs the service life of the gland.
The purpose of the utility model is realized by the following technical scheme:
a novel water pump gland comprises a gland body, wherein an end surface convex ring is formed on the inner end surface of the gland body, a first annular groove is formed on the end surface convex ring, an inner convex ring is formed on a water pump main body matched with the gland body in an inner convex mode, and a second annular groove is formed on the end surface of the inner convex ring; u-shaped sealing strips are inserted into the second ring groove and the first ring groove; the gland body middle part is formed with the shaft hole, has a plurality of screw holes along circumference, takes shape in the water pump main part to have the screw thread recess that corresponds with the screw hole.
In a further improvement, the upper part of the U-shaped sealing strip is in a cone frustum shape.
In a further improvement, a sealing ring gasket is arranged between the gland body and the water pump main body.
In a further improvement, a plurality of radial reinforcing ribs are formed on the outer end surface of the gland body along the circumferential direction.
In a further improvement, the reinforcing ribs are trapezoidal, and the width of the reinforcing ribs is gradually reduced from inside to outside.
The utility model has the beneficial effects that:
the utility model ensures the sealing performance, effectively prevents water leakage at the gland, increases the strength of the gland and prolongs the service life of the gland.
Drawings
The utility model is further illustrated by means of the attached drawings, the content of which is not in any way limitative of the utility model.
FIG. 1 is a schematic cross-sectional view of the present invention;
figure 2 is a schematic view of the outer end face structure of the gland body.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail with reference to the accompanying drawings and examples.
Example 1
As shown in fig. 1-2, the novel water pump gland (gland connection structure) comprises a gland body 1, wherein an end surface bulge loop 2 is formed on an inner end surface of the gland body 1, a first annular groove 3 is formed on the end surface bulge loop 2, an inner bulge loop 4 is formed on a water pump main body 9 matched with the gland body 1, and a second annular groove 5 is formed on an end surface of the inner bulge loop 4; u-shaped sealing strips 6 are inserted into the second annular groove 5 and the first annular groove 3; the middle part of the gland body 1 is provided with a shaft hole 7, a plurality of threaded holes 8 are formed along the circumferential direction, and a threaded groove 10 corresponding to the threaded holes 8 is formed on the water pump main body 9.
When the water pump is assembled, the gland body 1 is sleeved into the water pump main body 9, so that the end surface convex ring 2 is tightly contacted with the inner convex ring 4, and then the U-shaped sealing strip 6 is inserted into the first annular groove 3 and the second annular groove 5. When the water pump was used like this, the terminal surface of U-shaped sealing strip 6 can receive the terminal surface pressure of water to guaranteed sealed effect, effectively prevented current seal structure, when water pressure was too big or the bolt is not hard up, the condition of the joint gap department of leading to leaking easily.
The upper portion of the U-shaped weather strip 6 is preferably truncated cone-shaped. The water pressure all around that U-shaped sealing strip 6 received like this all has the pressure that conversion part is U-shaped sealing strip 6 to sealed effect is sealed in more effectual assurance. In order to further increase the sealing effect, a sealing ring gasket 11 is installed between the gland body 1 and the water pump main body 9.
Example 2
In addition to embodiment 2, in order to increase the strength of the gland body 1, a plurality of radial ribs 12 are welded or integrally cast on the outer end surface of the gland body 1 in the circumferential direction. The reinforcing ribs 12 are trapezoidal, and the width of the reinforcing ribs 12 gradually decreases from the inside to the outside. This is because gland body 1 middle part does not have effective support, and the outer end is connected with certain support through bolt and water pump body, because middle part pressurized bending deformation more easily, makes gland body 1 holistic bearing capacity more even through strengthening rib 12 like this, and has reduced the material, the cost is reduced.
Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the protection scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions can be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
