Description of the invention (1) [Invention and cutting technology field! The present invention relates to a ball valve used in various chemical factories, water treatment plants, nuclear energy related factories, and other various factories or facilities, and installed in the transport / control piping of various fluids to regulate the flow. [Known technology] Generally speaking, a ball valve is equipped with a valve ball with a through hole in the valve body, and the valve ball is controlled by an outside operating lever. M adjusts the opening degree of the valve ball through hole relative to the valve body. The purpose of controlling traffic. Furthermore, for example, in the conventional ball valve shown in FIG. 9, the inner end surface 103 of the primary fluid passage 102 and the inner end surface (not shown) of the secondary fluid passage 104 of the valve body are inclined. By forming each inclined surface 103 in an inclined shape, the opening area of the opening portion 105 in the center of the valve body can be made larger than that of a conventional ball valve. Therefore, the ball valve 107 can be installed in the valve body 101 with the valve ball 107 together with the primary valve seat assembly 108 and the secondary valve seat assembly (circle omitted) from the opening portion 105. In addition, when removing the primary valve seat fiber 106, the secondary valve seat assembly (not shown), and the valve ball IdM from the valve body ltn, check and repair the valve body. It is so large that it is easy to carry out inspection and maintenance or cleaning operations.

Description of the invention (7 ) Then, the surface side of "6" is fitted on the upper part 36, followed by the nut 39. Loosen to the desired valve ball 3 above. First, place the end face 8.a. The bottom 2a side of the end surface 8a is described. The inserted operation mechanism is fitted with the lower engaging piece 45 and the pressure cover 42, and the upper pressure part opening part 48 is installed. Install the nut 39 in sequence above the valve stem 41, and then turn the handle angle. The shape of the valve stem groove 17 at the front end of the valve stem 41 and the scale structure of the ball valve back plate 27 of the present invention are installed on the valve body. The installation form at this time is such that the opposite side and the back plate 27 are consumed by employees of the Intellectual Property Bureau of the Ministry of Economic Affairs Cooperative Du printing. However, the primary valve seat 18 is divided into the primary ball seat 22 and the primary ball seat 22, so that the secondary ball seat 5 is inserted into the primary seat seat 31. Next, the primary valve seat assembly 4 has one side end surface 15 of the ball 3, and the other side seat ball 3 of the secondary valve seat 3 and the secondary side valve seat have the valve ball seat 32 of the internal assembly 49 against Next to the assembly 4 and the valve, j holds the internal assembly 20 to elastically deform both sides of 4 9 to order once, let the valve stem 41 of the valve seat assembly mounting portion 36 on the primary side, count V gasket 44 from the cover, When the upper connecting piece 43 and the cover 42 close the operation mechanism and install the handle 38, the spring washer 40, and the hand 38, the valve stem 41 can be rotated to form a portion 41a that can be fastened to the upper inch. 1 At the time of assembly (refer to No. 5) 2 The inclined surface 29 of the back plate 27 of the primary side fluid passage 8 is located on the upper side with a thicker side and is arranged in the valve body 2 into a coil spring (19, 20), Ring valve seat assembly 4. On the other hand, 32, and the secondary ball seat 22 that forms the primary ball seat 22 abuts against the secondary ball ball of the valve side valve seat assembly 5 to form an internal assembly composed of the primary valve seat 5 The wide rod groove 17 of 49 '3 is located above, and the coil springs 19 and 4 of the side seat assembly 4 lean to the valve ball 3 side.

Description of the invention (8) In the state, the internal assembly 43 is opened from the opening of the valve body 2 The part 11 is installed in the valve body 2. At this time, the inclined surface 25 of the primary side valve seat assembly 4 of the internal assembly 49 slides on the inclined surface 2 9 of the back plate 2 7 provided in the valve body 2, so the internal fiber formation 4 9 is easy. Installed in the valve body 2. Furthermore, the front end 41a of the wide stalk 41 provided on the cover 6 is aligned with the valve rod groove 17 of the valve ball 3 of the internal fiber 49, so that the K-phase is engaged, and the shuttlecock 6 is engaged with the valve body. 2 的 dent portion 11a. Then, the screw inspection 12 is inserted into each hole 37 of the cover 6 and screwed into the screw hole 13 of the main body 2, and the ball 1 of the present invention is assembled. When the ball valve 1 of the present invention is used, the primary side fluid passage 8 and the secondary side flow passage 9 of the valve body 2 are respectively connected with pipes. Then, the valve ball 3 is rotated by the operation of the handle 38, so that the opening of the through hole 14 of the valve ball 3 to the fluid passage lf1 of the valve body 2 is changed correspondingly. In this way, the flow rate of the ball valve 1 can be adjusted to the desired flow rate. In addition, the ball valve 1 of the present invention is not limited to a manual type, and the valve ball 3 may be automatically operated using a fluid pressure such as air as shown in FIG. [Effect of the invention] As mentioned above, when the ball valve of the present invention is assembled, the primary valve seat assembly is slid on the inclined surface of the back plate, so that the primary valve seat assembly and the secondary wide seat assembly The clamped valve ball can be easily installed in the body. Furthermore, the ball valve of the present invention is installed in the valve body by a back plate having an inclined surface, that is, it is not necessary to make both ends of the valve ball or the primary side fluid path and the secondary side fluid in the valve body like the conventional ball valve. The inner side of the passage is uniformly shaped -11- This paper size applies to China National Standard (CNS) A4 (210 X 297 mm)

Description of the invention (9) It is inclined, compared with the conventional ball valve ', the ball valve of the present invention is easier to process and reduces the manufacturing cost. In addition, the opening is large, so parts replacement or inspection, maintenance, and cleaning of the valve body can be easily performed. In addition, by holding the valve ball on the primary valve seat assembly and the secondary valve seat assembly, the coil spring assembled in the primary valve seat assembly can be elastically deformed, and the primary valve seat assembly and the valve ball can be reduced. And the width of the secondary valve seat assembly is reduced, and the K is inserted into the valve body through the opening, so the installation operation is smoother. In addition, even if there is an abnormal pressure increase in the valve body, the pressure can be released into the piping through the elastic deformation of the coil spring without adversely affecting the components, covers, and operating mechanisms in the valve body. .
