Embodiment 1

[0025] see Figure 1~3 , in the embodiment of the present invention, an easy-to-install circumferential extension type preheating sealing device includes a sealing cylinder 1, a rubber block 2 detachably installed at the front end of the sealing cylinder 1, and a rubber block 2 for fixing the sealing cylinder 1 in the inner wall of the pipe fitting. Clamping assembly, wherein, the clamping assembly includes a threaded pipe 3 fixed in the center of the rear end of the sealing cylinder 1, a threaded screw 4 threaded with the threaded pipe 3, a circular platform extrusion block 6 connected to the front end of the screw 4 with bearings, The elastic expansion assembly matched with the round table extrusion block 6 is preferably fixedly connected to the rear end of the screw mandrel 4 with an adjustment wheel 5 for easy adjustment, and the rotation of the adjustment wheel 5 drives the screw shaft 4 to rotate, thereby driving the round table extrusion block 6. Move back and forth to ...

Embodiment 2

[0030] An easy-to-install method for using a circumferentially extending preheating sealing device, comprising the following steps:

[0031] Step 1, optional, by measuring the inner diameter of the pipe fitting, select the rubber block that matches it, and fix the selected rubber block on the front of the sealing cylinder with the fixing bolt;

[0032] Step 2, place, put the rubber block and the sealing cylinder into the pipe fitting together, and keep the rear part of the sealing cylinder outside the pipe fitting;

[0033] Step 3: Adjustment, turn the adjustment wheel to drive the screw to rotate, move the position of the round table adjustment block, and use the telescopic rod and the pull rod to fix the inner and outer walls of the pipe at the same time;

[0034] Step 4, coaxiality test, after the adjustment is completed, slightly pull the adjustment wheel to ensure that the device is firmly fixed in the pipe, and then turn the screw rod so that there is no axial gap.

Abstract

The invention discloses a circumference stretching type preheating sealing device convenient to install and a using method thereof, and particularly relates to a device for driving an elastic expanding component to extend along the circumference and fixed on the inner wall of a pipe along the circumference after a circular truncated cone extruding block moves forwards and backwards. When the circular truncated cone extruding block moves forward, a rolling wheel is driven to move upwards along the inclined side surface of the circular truncated cone extruding block so as to drive a telescopic rod to extend outwards, and an abutting block is firmly abutted against the inner wall of the pipe so as to fix a sealing cylinder in the pipe and the using method. The circumference stretching type preheating sealing device comprises a sealing cylinder, a rubber block and a clamping component, wherein the rubber block is detachably installed at the front end of the sealing cylinder, and the clamping component used for fixing the sealing cylinder in the inner wall of the pipe; and the clamping component comprises a threaded pipe, a lead screw, a circular truncated cone extrusion block and an elastic expansion component, wherein the threaded pipe is fixed to the center of the rear end of the sealing cylinder, the lead screw is connected with the threaded pipe in a threaded mode, the circulartruncated cone extrusion block is connected with the front end of the lead screw in a bearing mode, the elastic expansion component is matched with the circular truncated cone extrusion block, and the rear end of the lead screw is connected with an adjusting wheel which is convenient to adjust.

Description

technical field [0001] The invention relates to the field of sealing, in particular to an easy-to-install circumferentially extending preheating sealing device and its application method. Background technique [0002] There are many types of seals. For static seals, there are usually only two forms of gaskets and seal rings, and O-rings are the most widely used seal rings. For dynamic seals, packing seals are rarely used in chemical pumps. Mainly mechanical seals, mechanical seals are divided into single end face and double end face, balanced type and unbalanced type, and the balanced type is suitable for sealing of high-pressure medium. The double-end mechanical seal is mainly used for high-temperature, easy-to-crystallize, viscous, granule-containing, and toxic and volatile media. The double-end mechanical seal should inject spacer fluid into the sealing cavity. [0003] Most of the existing static sealing structures have a problem of poor stability, which tends to fall o...
