Referring to fig. 1 to 3, fig. 1 is a schematic view illustrating a valve joint anti-loose device according to an embodiment of the present invention; FIG. 2 shows a front view of the valve fitting check device of FIG. 1; fig. 3 shows a top view of the valve fitting check device shown in fig. 1. An embodiment of the present invention provides a valve fitting anti-loosening apparatus, which includes a first mounting assembly 100 and a fixing assembly. The fixing assembly is used for being arranged on one side, away from the valve 400, of the movable joint 500 of the valve 400, and comprises at least two fixing pieces 200 distributed along the circumferential direction of the outlet pipeline 600 of the valve 400, and any two adjacent fixing pieces 200 are connected through the first mounting assembly 100 and are used for being pressed on the outer diameter of the outlet pipeline 600.
When this valve connects locking device is when the installation is used, earlier set up the fixed subassembly in the loose joint 500 of valve 400 and deviate from one side of valve 400, two arbitrary adjacent mountings 200 are connected to rethread first installation component 100 to make mountings 200 compress tightly in the external diameter of export pipeline 600. Since the number of the fixing members 200 is plural, when the outer diameters of the outlet pipes 600 of different valves 400 are measured, the outer diameters of the outlet pipes 600 can be compressed by selecting different numbers of the fixing members 200, and the applicability is high.
Specifically, when the valve joint anti-loosening device is installed on the side, away from the valve 400, of the union 500 of the valve 400, when the valve 400 is opened or closed, the material in the pipeline can generate impact vibration due to the change of the flowing pressure of the material in the pipeline, so that the union 500 can be connected with the valve 400 to be loosened under the impact vibration of the material in the pipeline, and further the union 500 tends to move away from the side, away from the valve 400, and gradually separates from the valve 400. Because a plurality of mounting 200 of this valve joint locking device set up in the union 500 of valve 400 and deviate from one side of valve 400, and a plurality of mounting 200 all compress tightly in the external diameter of export pipeline 600 through first installation component 100, therefore mounting 200 can not do near the motion or keep away from the motion relatively valve 400, so when the union 500 moves to the lateral wall butt with mounting 200 under the impact vibration of the material in the pipeline, union 500 can not continue to do away from the motion relatively valve 400, make the motion of union 500 restricted, union 500 is difficult to break away from with valve 400, whole pipe-line system's safety and stability is higher.
With continued reference to fig. 1-3, in one embodiment, the securing assembly includes two securing members 200, and the two securing members 200 are disposed along the circumference of the outlet conduit 600 of the valve 400. The number of the first mounting assemblies 100 is two, two first mounting assemblies 100 are arranged at intervals on two radial sides of the outlet pipe 600 along the width direction of the fixing member 200, and the two fixing members 200 are connected and pressed on the outer diameter of the outlet pipe 600 through the two first mounting assemblies 100. When the fixing assembly needs to be installed on the side of the movable joint 500 of the valve 400, which is away from the valve 400, only two fixing members 200 need to be arranged along the circumference of the outlet pipeline 600 of the valve 400 and connected through two first installation assemblies 100, which is very simple and convenient. Because this valve connects locking device need not additionally set up with export pipeline 600 external diameter assorted clamp plate, therefore whole device's suitability is stronger. Of course, in other embodiments, the number of the fixing elements 200 may be three, four, five, etc., and the installer may select the size of the outer diameter of the outlet pipe 600 adaptively, but the number is not limited thereto, as long as the fixing elements 200 connected in sequence can be connected and pressed to the outer diameter of the outlet pipe 600 by the first mounting assembly 100.
