Abstract
The utility model provides a seal cover, this seal cover have the runner, and this seal cover still includes external seal part and interior seal part, and the tip of external seal part has oral area sealing. Further, a receiving portion is formed between the outer seal portion and the inner seal portion, and the receiving portion communicates with the flow passage. The accommodating part is a ring groove. The utility model has the advantages that: the utility model discloses the unique structure of seal cover can enough guarantee the leakproofness between seal cover and play water pipe and the last water pipe, can guarantee the sealed of seal cover and steel ball again, has reduced the spare part of product, improves product assembly efficiency.
Description
Technical Field
The utility model belongs to the technical field of the sealing member, especially, relate to automatic sealing member of watering insulating pot.
Background
In automatic watering insulating pot, need seal structure to carry out sealed cooperation between the inlet tube of the automatic water feeding device of coupler and the play water pipe, what present adopted between the two is that the spring pushes away the steel ball and the sealing member cooperation is sealed, also seals through the sealing member between inlet tube and the outlet pipe, so needs two sealing members, and sealed effect is not good moreover.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a seal cover that is difficult for leaking is provided.
The utility model discloses a realize through following technical scheme:
a kind of gland, this gland has flow path, this gland also includes the sealed part of external and internal seal, the end of the sealed part of external has sealing of the oral area.
Further, a receiving portion is formed between the outer seal portion and the inner seal portion, and the receiving portion communicates with the flow passage.
The accommodating part is a ring groove.
The utility model has the advantages that: the utility model discloses the unique structure of seal cover can enough guarantee the leakproofness between seal cover and play water pipe and the last water pipe, can guarantee the sealed of seal cover and steel ball again, has reduced the spare part of product, improves product assembly efficiency.
Drawings
Fig. 1 is a cross-sectional view of the present invention;
fig. 2 is a perspective view of the present invention.
Detailed Description
The present invention will be further described with reference to the following examples.
Examples
A sealing boot as shown in figures 1 and 2, having a flow passage 1, further comprising an outer sealing portion 2 and an inner sealing portion 3, the end of the outer sealing portion 2 having a mouth seal 4. The sealing sleeve is provided with an inner sealing part, an outer sealing part and an opening sealing part, so that the sealing sleeve can seal between the water inlet pipe and the water outlet pipe, the opening sealing part can be sealed with the steel balls, a containing part 5 is formed between the outer sealing part 2 and the inner sealing part 3, and the containing part 5 is communicated with the flow channel 1. The containing part 5 is arranged in such a way that residual water enters the containing part 5 after the steel balls and the sealing sleeves are sealed, the containing part 5 presses the inner sealing part and the outer sealing part under the water pressure, so that the sealing performance of the inner sealing part and the water inlet pipe is enhanced, and the sealing performance of the outer sealing part 2 and the water outlet pipe is enhanced. Effectively improving the sealing effect of the product. The accommodating part 5 is an annular groove. The whole seal cover be the silica gel material, and integral type structure as an organic whole.
The height of the end part of the inner sealing part 3 is lower than that of the end part of the outer sealing part 2, and a liquid port of the inner sealing part 3 is communicated with the accommodating part 5 after the sealing of the sealing sleeve. One end of the outer sealing part 2 is small in diameter, the other end of the outer sealing part 2 is large in diameter, and at least one part of the outer sealing part 2 forms a conical structure. The middle position of the outer sealing part in the embodiment is provided with a bending part 6, and the end part of the inner sealing part 3 extends to a position below the bending part 6. The arrangement of the bending part 6 increases the sealing area between the sealing sleeve and the sealed piece, thereby improving the sealing effect of the product.
And a bulge part 7 which is outwards protruded is arranged at one end of the outer sealing part 2 in the circumferential direction. The arrangement of the convex part 7 can facilitate the fixation of the installation, and the installation position is realized.
The inner end port of the flow channel of the inner sealing part 3 is small, and the end port of the flow channel is large. The inner sealing part 3 and the sealed piece are formed into a shape similar to a bell mouth, so that the sealing effect between the inner sealing part 3 and the sealed piece is better, the inner sealing part is inserted more tightly, and the sealing performance is improved.
This embodiment seal cover is when the water yield satisfies, and the inlet tube stops the water feeding, and the oral area sealing part of seal cover is sealed this moment, because there is residual water in the inlet tube, and residual water also has certain water pressure, and residual rivers form pressure to the periphery of holding portion behind the holding portion of seal cover to increase the inside and outside sealing performance of seal cover with by the sealing member, the good effect of not leaking appears.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only illustrative of the principles of the present invention, and that simple modifications and substitutions by those skilled in the art are within the scope of the present invention without departing from the spirit and scope of the present invention.
