具体的，手柄4符合人体手掌持握仿行式结构设置，且手柄4的前部内端开设有一处与阀杆3相配合的方形开孔，手柄4为球阀内部水流量的启闭装置。Specifically, the handle 4 conforms to the parallel structure of the palm of the human body, and the inner front end of the handle 4 is provided with a square opening that matches the valve stem 3, and the handle 4 is an opening and closing device for the water flow inside the ball valve.
本发明的工作方法：使用时，水流通过法兰5及第二法兰7进入本体2的内腔，当手柄4与本体2平行时，水流通过，并经第三法兰8及第四法兰10排出，当手柄4与本体2呈90度夹角时，球体1呈闭止状态，水流无法通过；注：当法兰5与第二法兰7、第三法兰8与第四法兰10在螺栓紧固的作用下，密封件6及第二密封件9被充分挤压到法兰5与第二法兰7、第三法兰8与第四法兰10内端的凹槽内，此时，法兰5与第二法兰7、第三法兰8与第四法兰10的内表面充分接触，使密封件6及第二密封件9达到了不会与水接触的效果。The working method of the present invention: when in use, the water flow enters the inner cavity of the body 2 through the flange 5 and the second flange 7, and when the handle 4 is parallel to the body 2, the water flow passes through and passes through the third flange 8 and the fourth flange 8. Flange 10 is discharged. When the angle between handle 4 and body 2 is 90 degrees, sphere 1 is in a closed state, and the water flow cannot pass through; Note: When flange 5 and second flange 7, third flange 8 and fourth flange Under the action of bolt fastening of flange 10, seal 6 and second seal 9 are fully squeezed into the grooves at the inner ends of flange 5 and second flange 7, third flange 8 and fourth flange 10 , at this time, the inner surfaces of the flange 5 and the second flange 7, the third flange 8 and the fourth flange 10 are fully in contact, so that the sealing member 6 and the second sealing member 9 achieve the effect of not being in contact with water .
综上所述：本发明一种全流量洁净型球阀连接密封件，通过密封件及第二密封件均为圆形状的三元乙丙橡胶材料结构，且密封件及第二密封件的外直径大于法兰及第二法兰、第三法兰及第四法兰的内直径，三元乙丙橡胶材料具有优越的耐氧化、抗臭氧及抗侵蚀的能力，密封件及第二密封件在法兰及第二法兰、第三法兰及第四法兰通过螺栓紧固的作用下，使法兰及第二法兰、第三法兰及第四法兰的内表面与密封件及第二密封件充分接触，使密封件及第二密封件达到了不与水接触，洁净度高的优点；通过法兰、第二法兰、第三法兰及第四法兰的内部均开设有与密封件及第二密封件相卡合的圆形开槽，且第二法兰及第三法兰的外端分别开设有与本体相连接的外螺纹，法兰及第二法兰、第三法兰及第四法兰上所开设的圆形开槽能够实现法兰与第二法兰、第三法兰与第四法兰的充分密闭，实现了密封效果好的优点；通过球体剖视为开设有全流量开孔的半圆形结构，且球体的外直径与本体的内直径相同，球体的内孔径大意味着过水量大，实现了球体流量大的优点；解决了上述中出现的密封件与水接触，洁净度差，密封效果低，且流量小的问题。To sum up: the present invention is a full-flow clean ball valve connecting seal, the seal and the second seal are both circular EPDM material structures, and the outer diameter of the seal and the second seal is It is larger than the inner diameter of the flange and the second flange, the third flange and the fourth flange. The EPDM material has excellent oxidation resistance, ozone resistance and corrosion resistance. The seal and the second seal are in Under the action of fastening the flange and the second flange, the third flange and the fourth flange through bolts, the inner surfaces of the flange and the second flange, the third flange and the fourth flange and the seal and The second seal is in full contact, so that the seal and the second seal have the advantages of no contact with water and high cleanliness; through the interior of the flange, the second flange, the third flange and the fourth flange There is a circular slot engaged with the seal and the second seal, and the outer ends of the second flange and the third flange are respectively provided with external threads connected with the body, the flange and the second flange, The circular slots on the third flange and the fourth flange can fully seal the flange and the second flange, the third flange and the fourth flange, and realize the advantages of good sealing effect; through the ball The cross-section is a semicircular structure with a full-flow opening, and the outer diameter of the sphere is the same as the inner diameter of the body. A large inner diameter of the sphere means a large amount of water passing through, realizing the advantages of a large flow rate of the sphere; solving the above problems The seals are in contact with water, the cleanliness is poor, the sealing effect is low, and the flow rate is small.
