Abstract
The utility model relates to a gate valve technical field, specific saying is a screw thread gate valve that dry-type is connected, including screw hole, valve body, sealing washer, the lower extreme both sides of valve body are equipped with a screw hole respectively, and the medial extremity of screw hole is equipped with the round slot, installs the sealing washer in the slot, and the pipeline inserts threaded hole, and the internal surface of sealing washer is attached at the tip surface of pipeline. Compared with the prior art, the sealing ring is arranged in the groove at the inner side end part of the threaded hole, so that water or a medium can be prevented from contacting with the thread, the thread is prevented from rusting, the sealing ring is not easy to slide out in the groove, the sealing performance is guaranteed, and the secondary sealing effect is achieved.
Description
Technical Field
The utility model relates to a gate valve technical field, specific say a screw thread gate valve that dry-type is connected.
Background
The screw mouth gate valve has the advantages that the threads of the screw mouth gate valve are sealed taper threads, and the threads cannot be protected by baking finish at the screw mouth, so that the threads are easy to rust, water pollution and untight threaded connection are indirectly caused, and leakage is generated.
Therefore, it is necessary to design a screw-threaded gate valve for dry connection.
Disclosure of Invention
The utility model discloses broken through the difficult problem of prior art, designed the screw thread gate valve that a dry-type is connected.
In order to achieve the purpose, the utility model discloses a screw thread gate valve that dry-type is connected, including screw hole, valve body, sealing washer, the lower extreme both sides of valve body are equipped with a screw hole respectively, and the medial extremity of screw hole is equipped with the round slot, installs the sealing washer in the slot, and the pipeline inserts threaded hole, and the internal surface of sealing washer is attached at the tip surface of pipeline.
The sealing ring is an O-shaped ring.
The pipeline is connected with the valve body by screw thread.
Compared with the prior art, the utility model, the sealing ring is arranged in the groove at the inner side end of the threaded hole, which can prevent water or medium from contacting with the thread and prevent the thread from rusting, and the sealing ring is not easy to slide out in the groove, thereby not only ensuring the sealing performance, but also having the secondary sealing effect; and for other methods of realizing sealing, the utility model discloses it is more convenient to install.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic structural diagram of the connecting pipeline of the present invention.
Detailed Description
The present invention will be further described with reference to the accompanying drawings.
Combine fig. 1~2, the utility model discloses a screw thread gate valve that dry-type is connected, including screw hole 1, valve body 2, sealing washer 3, the lower extreme both sides of valve body 2 are equipped with a screw hole 1 respectively, and the medial extremity of screw hole 1 is equipped with the round slot, installs sealing washer 3 in the slot, and pipeline 4 inserts in the screw hole 1, and the internal surface of sealing washer 3 is attached at the tip surface of pipeline 4.
The sealing ring 3 is an O-shaped ring.
The pipeline 4 is connected with the valve body 2 by screw thread.
The sealing ring 3 is arranged at the top end of the thread of the screw hole 5, so that the sealing performance is guaranteed, the secondary sealing effect is achieved, meanwhile, the problems of corrosion, rusting and the like of the thread of the valve body are solved by additionally arranging the sealing ring 3, the sealing effect is achieved, and the assembling process is very simple and convenient.
