Invention description (3) Simple. When replacing worn seals, as long as the 18 M gp of the valve body is removed, it can be easily replaced and replaced by κ, and the replacement of the loss component * is quite simple and convenient. The most advantageous surface shape of the sealing element is round * but it can also be polygonal. For round seals, the κ pressure fit is the best. When released, the outer surface of the sealing element can pass through the shape of the valve body. When closed, effective pressure and sealing effect are achieved. In another version of the invention * the sealing element forms a crown shape on its bottom surface. The crown shape allows the outer radial area of the sealing element to be compressed, so that the sealing element forms a function of a spring. It can be pressed into the connection hole provided in the housing to produce an effective seal. In addition, a spring element is provided between the sealing element and the bottom surface of the groove, thereby providing said and downward pressure. Another type of the present invention is to provide an annular groove on the bottom surface of the sealing element to contact an O-ring. The Q-shaped ring forms a spring * which is not used for sealing. In yet another version of the invention, the periphery of the selection shaft is surrounded by a sealing ring, which is connected to the valve® on one side, and the selection shaft is pre-pressed by a nut supported by the housing With. Because the sleeve sleeve needs to rotate frequently, so that the seal ring will wear a certain amount of friction after a period of use, so in the design of the present invention, a disc-shaped shrapnel is used, which has a compression effect The wear K of the sufficient M seal ring automatically achieves the effect of stopping leakage. In another version of the present invention, the ball valve body of the plug body has a paper standard of Chinese Standard (CNS) Α4 specification (210X297mm), which is easy to use. 83.5 5,000 0.88 (Please read the precautions on the back first (Fill in this page) * 1T Printed by the Ministry of Economic Affairs, Central Bureau of Accreditation, and Consumer Cooperatives A7 B7 5.

In another version of the invention there is a sleeve of a fairlead, preferably made of a sealing material, which can be pushed into the cylindrical section of the valve body. At the same time, a seal with a cover is also formed, which in one version of the invention may have a sealing ring. Appropriate non-stick materials, such as P T F E or similar materials, are particularly effective in preventing the product from passing through K when the valve body is closed, and preventing blockages between the gold element when the valve body is released.

The type and the grooves 6 2 a and 64 a Corresponding to the base. The bottom surface of the sealing element 6 6 a has an annular groove in which an o-ring is provided. Only the o-ring 70 of the sealing element 6 8 a can be seen in the fourth figure. The 0-shaped ring 70 acts like a spring and can seal the sealing element outwards in advance. * 8 ~ This paper size is applicable to the Chinese National Standard (CNS) A4 specification (210X297mm) 83.5 5,000 0.8ί ^ 1- Hu In I---II--i-- n ^ — Hi ^^^ 1 1 eJ (please read the notes on the back before filling out this page) A7 B7 Printed 5 by Beigong Consumer Cooperatives Description of the invention () 1 The sealing elements 6 6 and 6 8 or 6 6 a and 6 8 a can be manufactured from a material suitable for 1 1 > for example PTFEP but FE composite material > f I > graphite * ceramic t Jin Yi > and elastic material > end to see what you want to ask the temperature of 1 1 Depending on the medium 0 First read 1 1 Read 1 I The fifth figure shows a cross-sectional view of a ball valve 1 1 1 according to the invention. The back 1 I of the I I has a ball valve body 2 1 »which is equipped with L-shaped perforations 2 5 〇 Because of attention 1 1 thing 1 > except for 7 with the same each other-.

The valve body 2 1 1 2 b has. T-shaped hole 2 4 B This is also a two-way valve body 〇1 I — a single-one sealing element 6 6 b is provided in the proper 1 I groove of the ball valve body 2 2 b 0 other The function of the ball valve shown in the fifth picture and the sixth picture is 1 The function of K is achieved in the reciprocal way of the ball valve as described in the text. Therefore, it is no longer 1 1 detailed m Ming. In addition to this ball valve Similar to the aforementioned and 1 I and kk the same method is set in the valve body to kill 0 '1 I. Therefore, the present invention has the following characteristics: 1 1 * Small size »Light weight K and can Material saving 〇 Because the V series of the present invention is directly welded on the pipeline »Of course it is necessary to weld K in the open state to avoid injury I and the valve body» It is not necessary to set a flange ** 9-(FLANGE) is the basis for joining 1 1 1 1 1 1 This paper scale is suitable for countries in troubled countries (CNS M4 specification (210X297 mm) 83_5 5,000 0.88 Ministry of Economic Affairs Central Consumers Bureau Employees Consumer Cooperative Manufacturing A7 _ B7 _ V. Description of the invention (), can save at least four flanges and related screw bolts, and the sealing piece between the sugar and the flange, so it can save weight while eliminating material • and Therefore, the time taken for assembly can be reduced. In addition, the chance of leakage is greatly reduced because of the welded joint. 2. Because the shape of the inner surface of the housing is the same as the shape of the outer surface of the hemispherical valve, there is little room for stagnation, which can effectively reduce the trouble of the stagnation of the transported material and the resistance impact of the material on the ball valve. The inner surface M of the housing and the outer surface of the hemispherical valve body can be covered with wear-resistant K and anti-sticking materials, and can reliably prevent the stagnant image of the conveyed material. 4. The torque value of the stroke of 90 degrees from opening to closing of the present invention is almost the same low. And the sealing element made of P T F Ε material can greatly reduce the material stagnating on the outer surface of the ball valve, and can effectively reduce the resistance during twisting. 5 · To replace the component, simply screw it from the top surface, which is extremely convenient. In addition, according to the present invention, the sealing element of the material can be changed according to different temperature requirements and the characteristics of the fluid, so as to achieve the purpose of use and make the scope of application more extensive. 6 * The sealing element of the ball valve of the present invention does not support the weight of the ball valve as the bearing housing K like the sealing element of the conventional ball valve, so the wear of the sealing element can be minimized. 7 * The present invention can be used in the chemical industry, pharmaceutical industry, food industry (such as milk) or Wu Yaofu to send viscous substances, or there will be safety after leakage.
