The side covers 5 0 and 60 with inlet and outlet openings 5 1 and 61 are locked to both sides of the valve body 10, and the valve ball 20, ball cushion 30, and anti-leak block 40 are assembled and positioned; see In Figure 3, when the ball valve is closed, the drive shaft 11 can be used to control the turning of the valve ball 20 to close the two side covers 1230770 and the normal liquid flow between the two sides of the two sides. 4 3 while leak-proof blocks, and Tight use, to prevent the catastrophic block as a ball pad to leak the block position can not prevent] the main body of the ball pad push the < < < fire outlet $, and prevent the gap in the state can be done The downstream pipe ring is used; and gradually, the pipe flows into the ring at 0 and the valve. The pipe is attached to the valve ball to prevent the expansion and movement of the pipe. When the liquid is blocked, it is missing because it is as expected. Explanation (2) 5 0, 6 0 in the valve ball 2 0 1 0 ball socket 1 ball pad 3 0 in the swimming pipeline 4 0 is used as a pad 3 0 due to fire 2 0, resulting in loss of sealing work 4 1 through the runner The groove 4 2 makes the displacement to the inside to be a place for the sealing element, and furthermore, the anti-leakage, instead of being sufficient to push and prevent into an undeterminable manner, will be able to [invention of the present invention is that the valve has a ball pad, and # Among them, the liquid in the tube is a sealed junction from the line to the rear end, and the ball pad is referred to the 4th winding. That is, the liquid in the body is from the groove 4 2 and the ring groove 4 2 inside 2 0 The external, internal liquid and external liquid reduce the loss through the external line of liquid I #; Make sure that the ball pad 3, the valve ball 20, and the nozzle 6 1 are structured to ensure that the figure behind the 30 is the same. When the plastic method is tightly attached to the valve socket 12, the leaking block 40 and the liquid is gradually filled. Pressure to replace the ball pad to the downstream pipeline practical benefits. Inflowing pressure The liquid in the tube cannot be close to the valve and actuated by external pressure. The purpose is to provide-a kind of m-acting anti-moisturizing structure-a valve ball with through holes, and on the outside of both sides of the valve ball, a leak-proof block with several pushing blocks is covered by a solid low-temperature metal. Compressed 0 close to the valve body. Therefore, the ball made of the upper anti-leak block blocks the gap and perforates the entire ring. The 30 ring is made or installed without pressure. 1230770 Drive 5. Description of the invention (3) The side cover of the elastic element, under the ball, is a court disaster, and the leak-proof sheet can be detached from the element and is tightly attached to the liquid inside the valve tube to prevent disaster. The present invention, wherein the elastic compression element of the top compression is more than low. The metallographic change of temperature is composed of pieces, and then facilitates automatic sensing. [For the purpose of understanding, please refer to the valve ball of the fifth moving shaft 7 1, 8 1 with a recess 8 1 > One of the inlet and outlet openings on both sides of the lock and the anti-leakage piece assembly positioning; by this, the ball valve is placed against the ball in the normal shape as a leak-proof seal, but the plastic ball cushion is caused by fire When the fire field is gradually burned due to the high temperature, use itself to push The phase of the low-temperature metal changes, so that the bullet is compressed and fixed, and then pushes and pushes the anti-leak sheet to displace. On the ball, it is used as a sealing element instead of the ball pad, and it is prevented from leaking to the downstream pipeline or installation place. It has the practical benefit of being expanded to prevent leakage. Another purpose is to provide a ball valve with a reliable anti-leakage structure. The push block is cast and covered with molten liquid low-temperature metal, and the low-temperature metal is cooled and solidified to form a coated solid-temperature low-temperature metal block. ; By this, when the high-temperature environment of the fire site is the melting point, the solid low-temperature metal is automatically sensed. ^ The solid is converted into a liquid, and the compressed elastic element is released. The elasticity of the elastic element is used to push the displacement of the anti-leak sheet. To achieve the purpose of action. …] Your reviewing committee has made a further preferred embodiment of the structure and efficacy of this case and cooperated with the drawings, which will be described in detail as follows: Figures y and 6, there is a drive above the valve body 70 of the present invention and the interior has A ball socket 7 2 is provided for installation-the top mask is recessed 80, and the valve ball 80 is internally provided with a through hole 8 2 horizontally, and the drive shaft 7 of the valve body 70 is embedded to drive and control the 1230770. 、 Explanation of the invention (4) Closed, two engineering plastics are set with an 8 4 1 on the outer side, and 8 4 2 on the outside are provided with 9 1 1 side covers 9 balls 8 0, ball pads 8 Please refer to the 7th series One of the lower molds is spring 8 5 1 and spring 8 5 1, so that the point in the cavity of the washing tool of the upper mold is about 100%. Special alloy is taken as an example. The phase change is from solid 8 5 2 to Cooling and condensing inside, forming an 8 5 'ball position inside' and forming a compression but removing the elastic energy stored in low temperature metal Benin, please refer to the 9th body 7 〇 drive 8 〇 through hole 8 2 ball The pad 8 3 is equipped with an anti-electric plate 8 4. The anti-plate surface is concavely provided with a plurality of jacking blocks 8 5, and it is locked to the valve 3 and the anti-leak plate 8 with 0, 9 1 groups. Figure 8, the mold cavity of the present invention has a built-in elasticity and another with a pouring spring 8 5 1 inside the mouthwash ~ molten liquid low temperature metal 8 5 2 can be about 3 0 ° C, its valley temperature About 1 changes to a liquid state, and then solidifies, and will soon be compressed into a solid block shape; when the yellow 8 5 1 series receives a low shape and stores the elastic limit of 8 5 2, it takes a relatively large elastic diagram. In the present invention, when the shaft 7 1 is to be opened, the control valve and the two side covers 9 0, 9 are placed on the valve plate 8 0, and the drain plate 8 4 is provided with a slot 8 ″; the inlet and outlet 9 body 7 Q > ^ 7 u are mounted on both sides. The ejector block 8 5 is used to make the component. The low temperature metal 8 5 2 in the cavity of the mold under the mold is closed above the elastic element. t 'Exceeded is the lower solid state of the spring 8 5 1 in the lower mold', which pushes the energy of the warm metal 8 5 2 into the block, and the spring 8 5 1 will stretch outward. At that time, the ball 8 can be opened, so that both sides of the water inlet and the water outlet can be perforated. 1. 'When the valve is operated, the parts are compressed and compressed', and then Models, etc., will be produced to produce the fixed limit of the warm metal covering block, so once it is released, the valve valve ball 1230770 V. Description of the invention (5) 9 0 1, 9 1 1 communicate with each other, and the ball pad 8 3 is tight. Stick to the outside of both ends of the valve ball 80 through hole 8 2 to prevent the liquid in the tube from flowing into the gap between the valve ball 80 and the valve body 70 ball socket 72 and leaking to the other end, which can be used for the upstream pipeline. The internal liquid flows to the downstream pipeline. Referring to FIG. 10, when the ball valve is closed according to the present invention, the drive shaft 7 1 of the valve body 70 can be driven to control the turning of the valve ball 80, and the two side covers t 90 and 91 can be inserted into and discharged from the water outlets 901 and 91. 1 block, and the ball pad 8 3 is closely attached to both sides of the valve ball 80 to prevent the liquid in the tube from flowing into the gap between the valve ball 80 and the valve body 70 ball socket 7 2 so that it leaks to the other One end, therefore, the ball pad 8 3 can be used as a sealing structure in a normal state to call to block the liquid flow in the upstream pipeline to the downstream pipeline. Used as a spacer ring. Please refer to FIG. 11 and FIG. 12. According to the present invention, in the event of a fire disaster, the ball pad 8 3 is gradually burned due to the high temperature of the fire field, and cannot be closely attached to the valve ball 8 0, resulting in the valve ball 8 0 There is a gap between the ball and socket 7 2 of the valve body 70 and the sealing function is lost. At this time, the pushing block 8 5 on the anti-leak sheet 8 4 will cause the temperature of the fire field to exceed the low temperature metal 8 5 2 melting point, and the low temperature metal '8 5 2 That is, the phase change occurs automatically. The solid state changes to the liquid state. Because the compressed spring 85 1 is fixed without external force, it can release the elastic force and stretch outwards, and push the anti-leak sheet 8 4 to displace and close to the valve. The outside of the ball 80 is used as a sealing element instead of the ball pad 83 to prevent liquid in the pipe from flowing into the gap between the valve ball 80 and the valve body 70 ball and socket 72 and leaking to the downstream pipeline or device. Set up a place to achieve the practical benefits of automatic sensing and actual action to prevent leakage, and to prevent the expansion of disasters and reduce losses.
