Description of the Invention (/) [Technical Field] The present invention is mainly related to the improvement of the integrated 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 plug body 'by rotating the plug body 90 degrees to open and close the flow path. This type of water stopcock has existed before, and many forms have been proposed for improving the body of the plug or its joint. [Problems to be Solved by the Invention] However, the conventional ball type water stopcock has a problem in a joint portion. That is, a water stopper capable of connecting different water pipes to the joint portions on both sides, for example, a polyvinyl chloride pipe and a stainless steel pipe, respectively, has not been proposed. In fact, the tube ends must be machined for-joining. Therefore, the conventional ball type water stopcock has the disadvantages of poor workability during piping construction and high construction cost. In addition, due to the low connection strength, if an external force is applied during use, the water pipe may be simply pulled out. In view of these problems, the present invention provides a joint integration ball that can connect different types of water pipes on both sides of the joint without any processing of the water pipe, and can be simply connected by inserting one end of the pipe. Water stopcock. The invention also provides an integrated ball-type water stopper which can be simply and firmly connected to a polyvinyl chloride pipe at one end and a stainless steel pipe at the other end. In addition, the present invention provides a joint-integrated ball type water stopper that can relatively easily connect and remove water pipes.

Description of the invention (') 1. A ball plug body 12 is housed inside the body frame u constituting the outer shell of the plug body 1. The ball bolt body 12 is connected to the handle 13 'By rotating the handle 13, the ball bolt body 12 can be rotated inside the body frame 11. The ball tether body 12 is formed with a through hole 14 ′ which is formed in a through shape, and can be opened and closed by turning 90 degrees. The 'ball plug body 2' is sandwiched by a synthetic resin ball seat 15 and is held at a certain position β by a ball pressing member 16. 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 connecting the polyvinyl chloride pipe A side will be described. As shown in FIG. 1 and FIG. 2, a packing 21, a washer 22, and a sleeve are inserted inside the socket 20 of the main body frame 11 in order from the deepest position. )twenty three. The gasket 21 is made of a synthetic resin having a moderate elasticity, and the gasket 22 is made of a hard synthetic resin. 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 as a metal product for H, and the outer surface of the sleeve 23 is formed as a tapered surface 26. A tapered surface 28 is formed on the inner surface of the sleeve pressing member 27. The tapered surface 28 has the same inclination angle as the tapered surface 26 of the sleeve. Therefore, when the sleeve pressing member 27 is screwed into the inner surface of the socket 20, the two tapered surfaces 26, 28 will contact the sleeve 23 and will be pressed toward the inside of the socket while undergoing shrinkage deformation. On the other hand, 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 tube 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 paper surface of the zigzag surface b of the inner surface thereof is applicable to the Chinese National Standard Complete (CNS) A4 specification ⑽ x 297 public hair) I-^ 1 --- I ----- ! _ Install ---- Jil — Order --------- line (please read the precautions on the back, and then / i / this page) Printed by A7 409169 B7 of the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs Explanation of the invention (+) 25 will be strongly crimped and pushed into the outside of the pipe A, so that the pipe A can be prevented from being pulled out. Further, as shown in the figure, o-rings 29 are attached to the inner surface and the outer surface of the sleeve pressing member 27. Since the joint portion 2 has the structure as described above, the connection operation of the tube A is first to loosen the screwed state of the sleeve pressing member 27, and insert one end of the tube A into the socket 20. 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 fully inserting the tube A, tighten the sleeve to press the screw of the structure 仵 27. As a result, as described above, the gasket 21 is compressed and the sleeve 23 is reduced in diameter and deformed to produce 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 described above, when the pipe A is connected to the joint portion 2, there is no need to perform any processing on the pipe end. Therefore, the connection work of the pipes is extremely simple. The type of the pipe A is not particularly limited. Although a rigid polyvinyl chloride pipe for a water pipe is most suitable, it can also be connected to other synthetic resin pipes, steel pipes, and copper pipes. Next, the joint portion 3 on the other side that connects the stainless steel pipe B will be described. As shown in FIGS. 1 and 3, the joint portion 3 is attached to the ball pressing member 16. The ball pressing member 16 has a slightly cylindrical shape, and the inside of the ball pressing member 16 can be inserted into the tube B. A tapered surface 30 is formed on the open end of the ball pressing member 16, and a washer 31 made of synthetic rubber is fitted into the tapered surface 30. A cap nut 32 is screwed onto one end of the ball pressing member 16. A tapered surface 33 is formed on the inner surface of the cap nut 32, which will hold the structure. 6 This paper size is in accordance with China National Standard (CNS) A4 (210 X 297 mm>)
