具体实施方式Detailed ways
下面结合具体实施方式对本实用新型进行详细说明。The utility model will be described in detail below in conjunction with specific embodiments.
本实用新型提供的用于紧固及打开管路连接处法兰的装置的结构如图1所示，包括分别位于固连的法兰6两侧并且套设于管路5上的两个夹紧部件组成，每个夹紧部件由两个相对设置的抱箍2组成，两个相对设置的抱箍2之间通过紧固件3连接，相对设置于法兰6两侧的紧固件3之间通过花篮螺丝4连接。花篮螺丝4选用两端是圆孔的OO型花篮螺丝，它由两个分别左旋和右旋的螺杆以及连接螺杆的调节杆组成。The structure of the device for fastening and opening the flange of the pipeline connection provided by the utility model is shown in Figure 1, including two clamps respectively located on both sides of the fixed flange 6 and sleeved on the pipeline 5 Each clamping part is composed of two oppositely arranged hoops 2, and the two oppositely arranged hoops 2 are connected by fasteners 3, and the fasteners 3 arranged on both sides of the flange 6 are opposite to each other. They are connected by turnbuckle 4. Turnbuckle 4 selects the OO type turnbuckle that two ends are circular holes for use, and it is made up of two respectively left-handed and right-handed screw rods and the adjusting rod connecting screw rods.
为了防止夹紧部件在管路5上的滑动，因此在夹紧部件与管路5之间铺设摩擦层1，摩擦层1为橡胶皮套。In order to prevent the clamping part from sliding on the pipeline 5, a friction layer 1 is laid between the clamping part and the pipeline 5, and the friction layer 1 is a rubber sheath.
紧固件3为配套设置的螺栓和螺母，花篮螺丝4的O形两端套设在相对设置于抱箍2中间位置的紧固件3的螺栓上。The fastener 3 is a set of bolts and nuts, and the O-shaped ends of the turnbuckle 4 are sleeved on the bolts of the fastener 3 that are relatively arranged in the middle of the hoop 2 .
连接两条管路5两端的法兰6时，先用螺栓和螺母将法兰6进行固定，然后在法兰6两侧的管路5上分别卷设一层由橡胶皮套构成的摩擦层1，然后在摩擦层1上将两个抱箍2相对放置，将花篮螺丝4的两端圆孔位于抱箍2的安装耳之间，在通过紧固件3的螺栓穿过花篮螺丝4的圆孔后和螺母进行固定，此时，通过旋转花篮螺丝4的调节杆向内收紧其两端的螺杆使得法兰6的连接更为紧密，避免了管路5内液体的渗漏；而当需要打开两个固联的法兰6时，先将固定法兰6的螺栓、螺母拆掉，然后反向旋转花篮螺丝4的调节杆使得其两端的螺杆向外旋出，由于抱箍2组成的夹紧部件固定在管路5上，因此该向外旋出的推力会将由于锈蚀连接在一起的法兰6撑开，同时由于不使用撬棍等工具强行撬开粘连的法兰6，因而也避免了对法兰6造成损坏。When connecting the flanges 6 at both ends of the two pipelines 5, first fix the flanges 6 with bolts and nuts, and then roll a friction layer made of rubber sheaths on the pipelines 5 on both sides of the flange 6 1. Then place the two hoops 2 opposite each other on the friction layer 1, place the round holes at both ends of the turnbuckle 4 between the mounting ears of the hoop 2, and pass the bolt of the fastener 3 through the turnbuckle 4 After the round hole is fixed with the nut, at this time, the screw rods at both ends are tightened inwardly by rotating the adjusting rod of the turnbuckle 4 to make the connection of the flange 6 more tightly, avoiding the leakage of the liquid in the pipeline 5; and when When it is necessary to open the two fixed flanges 6, first remove the bolts and nuts that fix the flanges 6, and then reversely rotate the adjusting rod of the turnbuckle 4 so that the screws at both ends are screwed out. The clamping part is fixed on the pipeline 5, so the thrust of the outward rotation will spread the flanges 6 connected together due to corrosion, and at the same time, because the crowbar and other tools are not used to forcibly pry the flanges 6 open, Damage to the flange 6 is thus also avoided.
