Description of the invention (/) Description of the invention: [Technical Field] The present invention is mainly related to the improvement of the ball type water stopcock used in the water pipe. [Conventional Technology] The so-called ball type water stopcock is a water stopper that uses a spherical body and rotates the body 90 degrees to open and close the flow path. This type of water-stop inspection has existed from the past, and many proposals have been made for various modifications to the bolt body or its joints. [Problems to be Solved by the Invention] However, the conventional ball type water stopper is not perfect in practical use due to problems in the joint portion. That is, the water stopper is connected to a water pipe or various equipment on both sides thereof. Due to insufficient improvement of the joint portion, or the work during connection will become more laborious, or due to the low connection strength, there is a pipe in use from the joint Problems of ministry separation.

The present invention also provides a ball stopcock which can be simply and strongly connected to various water pipes such as a polyvinyl chloride pipe, a polyethylene pipe, and a steel pipe. The present invention also provides a ball-type water stopcock having a telescopic function. [Means for Solving the Problems] The technical means of the ball type water stopper of the present invention includes a plug body in which a ball plug body is housed in a body frame, and two joint portions provided on both sides of the plug body. Ball type water stopcock; 3 This paper size is in accordance with Chinese National Standard (CNS) A4 (210 X 297 public glass) Γ (Please read the note on the back before filling in this page) Binding · Staff of Intellectual Property Bureau, Ministry of Economic Affairs Printed by the Consumer Cooperative Α7 Β7 Printed by the Intellectual Property Bureau of the Ministry of Economic Affairs, co-printed by Du, F. 5. Description of the invention Hold it; the joint part on the other side is a flexible joint with a short tube that can be moved in the axial direction. The joint part on one side is preferably: the socket of the body skeleton, screwed to the socket of the socket The sleeve pressing member is composed of a sleeve that is in contact with the inclined surface and the sleeve pressing member, and a gasket fitted in the socket. The sleeve is a ring with a 1 cutout, and the inside The surface forms a friction surface. When the sleeve pressing member is pressed into the socket, The barrel will be pressed deep to compress the gasket and reduce the diameter of the sleeve, so that the friction surface is crimped to the outside of the tube. The joint part on the other side is preferably provided with: screwed onto the body frame A ball compression member, one end of which is embedded in the short tube on the inner surface of the connection portion of the ball compression member, and a cap nut screwed to one end of the connection portion to prevent the short tube from being pulled out, installed at the front end of the short tube The cap nut for connection; the short tube can move freely along the axial direction in the connection portion. [Embodiment of the invention] The embodiment of the ball type water stopper of the present invention will be described based on the embodiment of the drawing. As shown in FIG. 1, the ball type water stopcock is composed of the plug body 1 and the joint portions 2 and 3 on both sides of the plug body. First, the plug body 1 will be described. The ball plug body 12 is accommodated in the inside »The ball plug body 12 and the handle 13 are connected, and the ball plug body 12 can be rotated inside the body frame 11 by turning the handle 13.

Description of the invention (3) The seat 15 is clamped, and the member 16 is pressed by a ball to keep it The ball pressing member 16 is screwed and fixed to the main body frame 11. Next, among the two joint portions, the joint portion 2 on the connection pipe A side will be described. As shown in Figs. 1 and 2 Generally, a packing 21, a washer 22, and a sleeve 23 are embedded in the socket 20 of the main body frame 11 in order from the deepest position. The gasket 21 is made of a synthetic resin having a moderate elasticity, the gasket 22 is made of a hard synthetic resin, and the shapes of the gasket 21 and the gasket 22 are completely annular. The sleeve 23 is made of a metal such as a copper alloy, and has a ring shape with one cutout 24, so that the diameter of the ring can be enlarged and reduced. In addition, the inner surface of the sleeve 23 is formed with a serrated or uneven friction surface 25 having an appropriate shape for the purpose of preventing slippage, and the outer surface of the sleeve 23 is formed with an inclined surface 26. An inclined surface 28 is formed on the inner surface of the sleeve pressing member 27. The inclined angle of the inclined surface 28 is the same as that of the inclined surface 26 of the sleeve described above. Therefore, when the sleeve pressing member 27 is screwed into the inner surface of the socket 20, the two inclined surfaces 26 and 28 will contact, and the sleeve 23 will be pressed toward the inside of the socket while being reduced in diameter. As a result, the gasket 21 will be compressed by receiving a force from the outside, and the inner surface of the socket 20 and the outer surface of the pipe A will be forced to closely contact each other to prevent water leakage between the gaps. In addition, due to the reduced diameter deformation of the sleeve 23, the inner friction surface 25 will be strongly crimped and bite into the outside of the pipe A, so that the pipe A can be prevented from being pulled out. An O-ring 29 is attached to the inner surface of the sleeve 27 as shown in the figure. Since the joint part 2 is formed into the aforementioned structure, the connection operation of the pipe A is first to loosen the screwed state of the sleeve pressing member 27, and the pipe A will be used. 5 This paper size applies to Chinese National Standard (CNS) A4 Specifications (210 X 297 male «) lilt ---! — I > ^ · ----.

Description of the invention (middle) Insert the socket 20 into the socket. At this time, since the sleeve 23 is in an enlarged diameter state and there is no external force acting on the gasket 21, there is no resistance to the insertion of the tube A, and it can be easily inserted. After the tube A is fully inserted, the tightening sleeve tightens the screwing of the member 27. As a result, as described above, the gasket 21 is compressed, and the sleeve 23 is reduced in diameter, which results in a water leakage prevention effect and a pullout prevention effect. When the connected pipe A is to be pulled out, first, the screwing of the sleeve pressing member 27 is loosened. As a result, the sleeve 23 will be enlarged in diameter, and the compressive force acting on the gasket 21 will disappear, so that the tube A can be easily pulled out. As above, when connecting the pipe A to the joint part 2, it is not necessary to align the pipe end --------------------- ^

In addition, the present invention is not limited to the foregoing embodiments, and various modifications can be made within the scope described in the patent application scope. In particular, the detailed structure of the bolt body 1 and the joint portions 2 and 3 on both sides can be changed freely. [Effects of the Invention] Since the ball type water stopcock of the present invention is a joint for pipes, and the joint part on the other side is an expansion joint, connection work for piping construction can be carried out extremely easily and practically very convenient. In addition, since the joint portion for the pipe is a defect type in which the sleeve is crimped to the outside of the pipe to fix and hold the pipe, the pipe can be simply and strongly connected without performing any processing on the pipe. In addition, since the other joint part is formed to be flexible, the connection operation is extremely easy. Even if an external force in the axial direction acts on the pipeline after the connection, the external force can be absorbed to prevent the pipeline from being damaged.
