Description
Technical Field
The invention relates to a spring clamp for a pressure container and a manufacturing method thereof.
Background
For the pressure container with the filling medium coexisting in gas-liquid phase, a pipe fitting from top to bottom is generally arranged in the structure of the pressure container, and when the pressure container is in a straight state, a valve on the pressure container is opened, and the liquid in the pressure container can be outwards extruded out along the pipe fitting under the action of internal pressure; wherein, the upper end of the pipe fitting is fixedly bonded with the valve body or fixed by screw threads. Because the pipe fitting is longer, when pressure vessel removed or used, the pipe fitting can rock always, and the fixed effect of pipe fitting upper end can worsen, and long-time the use can lead to the condition that the pipe fitting drops to take place.
The invention of application No. 202021634238.7 discloses an elastic pipe clamp to realize the positioning and fixing of the pipe fitting, but the spring clamp can not be matched with the existing pressure container to realize the positioning and fixing of the lower end of the pipe fitting.
Disclosure of Invention
The invention aims to provide a spring clamp for a pressure container, which can limit the shaking of the lower end of a pipe fitting.
In order to achieve the purpose, the invention adopts the following technical scheme: the utility model provides a spring clamp for pressure vessel, includes about relative setting and makes two elasticity clamping parts by elastic material, is equipped with connecting portion between two elasticity clamping part lower extremes, constitute between two elasticity clamping parts and run through and the open-ended groove of stepping down that makes progress around having, be equipped with on the elasticity clamping part inner wall and step down the constant head tank that the groove communicates and move towards another elasticity clamping part, the constant head tank upwards extends and the opening that makes progress along elasticity clamping part.
When the lower end of the guide pipe in the pressure container needs to be positioned, the spring clamp is fixed in the pressure container in a welding fixing or bolt fastening mode, then the pipe to be positioned is moved, so that the pipe is downwards inserted into the positioning groove of the elastic clamping part, the pipe is clamped and positioned through elastic clamping between the two elastic clamping parts, and the radial movement of the pipe is limited through the arrangement of the positioning groove.
Preferably, the inner walls of the two elastic clamping parts are respectively provided with one positioning groove, and the two positioning grooves correspond to each other left and right. Through all setting up the constant head tank on two elasticity clamping parts to the part all has the spacing of partly surrounding shape about making the pipe fitting, with the spacing effect in location that improves the pipe fitting.
Preferably, the sectional shape of the groove surface of the positioning groove is the same as the outer edge shape of the sectional part of the pipe fitting to be positioned. Above-mentioned setting is so that constant head tank groove face can better with the contact of pipe fitting outer wall to be positioned to increase elasticity clamping part and pipe fitting area of contact, with the gap between further dwindling pipe fitting and elasticity clamping part, thereby realize the restriction to pipe radial movement better. When the pipe fitting to be positioned is a square pipe, processing the positioning groove into a U-shaped groove; when the pipe fitting to be positioned is a round pipe, the positioning groove is processed into an arc-shaped groove.
Preferably, the elastic clamping part and the connecting part are integrally formed, and the lower end of the elastic clamping part is smoothly connected with the edge of the connecting part to form an arc-shaped structure. The arrangement makes the clamping, positioning and fixing of the pipe more convenient, and is also convenient for processing and manufacturing the spring clamp. When the pipe fitting enters the positioning groove downwards, as long as the distance between the two elastic clamping parts is smaller than the width of the pipe fitting, the distance between the two elastic clamping parts is expanded, so that the pipe fitting is clamped between the two elastic clamping parts.
As preferred, the elasticity clamping part includes the direction section from top to bottom in proper order and is used for the grip segment of centre gripping pipe fitting, the direction section sets up along upper and lower direction slope, and controls the distance between two direction sections and from top to bottom reduce gradually, the grip segment with the direction section all has the constant head tank. Through setting up the upper segment to treat the downstream of location pipe fitting and lead, so that the pipe fitting lower extreme stretches into in the constant head tank. Meanwhile, the pipe fitting can be prevented from being abutted and collided with the elastic clamping part.
Preferably, the elastic clamping part comprises a deformation section and a clamping section for clamping the pipe fitting from bottom to top in sequence, the deformation section is obliquely arranged along the vertical direction, and the distance between the left deformation section and the right deformation section is gradually increased from top to bottom. Because the lower section of the elastic clamping part is obliquely arranged, when the pipe passes through the clamping section, the contact surface between the pipe and the lower section is less or even not, the resistance for assembling the pipe and the spring clamp can be reduced, and the lower section of the elastic clamping part can be better expanded and deformed.
Preferably, the connecting part is a sheet structure arranged along the left-right direction, and the middle part of the connecting part is provided with a plurality of extending parts extending forwards or backwards. The contact area between the spring clamp and the inner wall of the pressure container is increased by the arrangement, so that the spring clamp and the pressure container are convenient to weld and fix or fasten by bolts.
The invention also discloses a manufacturing method of the spring clamp, which comprises the following steps: (1) pressing the left end and the right end of the strip-shaped sheet workpiece along the length direction out of the positioning grooves extending along the length direction of the workpiece; (2) the workpiece is divided into a connecting part and elastic clamping parts positioned on the left side and the right side of the connecting part, the bending between the elastic clamping parts and the connecting part is carried out, and the elastic clamping parts are bent to be above the connecting part.
Preferably, in the step (1), after the positioning groove is punched, two ends of the workpiece, which are provided with the positioning groove, are bent downwards; and the end part of the workpiece with the positioning groove is bent into a circular arc shape.
Preferably, in the step (2), after the bending between the elastic clamping portion and the connecting portion is completed, the distance between the two elastic clamping portions is adjusted according to the outer diameter of the pipe to be positioned.
The spring clamp which can be matched with the existing pressure container for use is arranged to clamp and position the lower end of the pipe fitting, so that the shaking of the lower end of the guide pipe can be limited, the positioning of the pipe fitting in the height direction can be realized, the shaking amplitude of the pipe fitting can be reduced, the upper end of the pipe fitting is prevented from being separated from the pressure container, and the service life of the pipe fitting is prolonged; the spring clamp has the advantages of simple structure, convenient manufacture, simple fixing mode with the pressure container and lower production cost.
