本发明可泄压堵头的使用过程为：The use process of the pressure relief plug of the present invention is:
安装过程：首先将堵头帽安装到堵头壳体，形成完整的可泄压堵头，然后将堵头壳体的一端连接到管道端头，优选通过螺纹进行连接。在进行带压安装时，将堵头帽安装到堵头壳体，并且使凸起推动所述密封弹片移动一定距离，此时将堵头壳体的一端连接到管道端头，安装完毕后旋转堵头帽且使弹簧推动密封片密封第一泄压孔，完成安装。Installation process: First install the plug cap to the plug housing to form a complete pressure-relieving plug, then connect one end of the plug housing to the pipe end, preferably by threading. When installing under pressure, install the plug cap to the plug housing, and make the protrusion push the sealing shrapnel to move a certain distance. At this time, connect one end of the plug housing to the end of the pipe, and rotate after installation Plug the cap and make the spring push the sealing sheet to seal the first pressure relief hole, completing the installation.
检查气密性和泄压过程：旋转堵头帽，使凸起推动所述密封弹片移动一定距离，此时管道内带压液体可以通过第一泄压孔，进而经堵头帽的第二泄压孔流出；检查完毕或泄压完毕时，反方向旋转堵头帽，使凸起收回，弹簧推动密封片密封第一泄压孔，管道内带压液体不再外泄，在检查和泄压过程中能够保证操作人员的人身安全。在具体的实施过程中，有多种形式的固定件11来固定弹簧位置。如，通过中空的卡环限定弹簧位置，将卡环通过焊接、粘结等方式固定在堵头壳体内壁。在优选的实施例中，如图5所示，所述固定件11为透空外攻丝六角螺母,螺母本体为圆柱形，外壁为丝扣114，内部为正六边形空腔112，所述堵头壳体内壁具有与之配合的螺纹。这种实施方式的优点是弹簧对密封弹片施加的预紧力可以通过旋转螺母来进行调节。Check the air tightness and pressure relief process: Rotate the plug cap to make the protrusion push the sealing shrapnel to move a certain distance. At this time, the pressurized liquid in the pipeline can pass through the first pressure relief hole, and then pass through the second pressure relief hole of the plug cap. The pressure hole flows out; when the inspection or pressure relief is completed, rotate the plug cap in the opposite direction to retract the protrusion, and the spring pushes the sealing sheet to seal the first pressure relief hole, and the pressurized liquid in the pipeline will no longer leak out. The personal safety of the operator can be guaranteed during the process. In a specific implementation process, there are various forms of fixing pieces 11 to fix the position of the spring. For example, the position of the spring is defined by a hollow snap ring, and the snap ring is fixed on the inner wall of the plug housing by means of welding or bonding. In a preferred embodiment, as shown in FIG. 5, the fixing member 11 is a hexagonal nut with a hollow outer thread, the nut body is cylindrical, the outer wall is a threaded thread 114, and the inside is a regular hexagonal cavity 112. The inner wall of the plug housing has threads matched therewith. The advantage of this embodiment is that the pre-tightening force exerted by the spring on the sealing shrapnel can be adjusted by rotating the nut.
