Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to an anti-leakage valve. Background Art

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and adjust and control the parameters (temperature, pressure and flow) of the conveying medium.

[0003] However, the valve connection method in the prior art is usually flange connection, which leads to gaps in the installation of the delivery pipe and poor sealing. At the same time, due to the flange connection, the delivery pipe cannot be easily swung, so once it is impacted, the delivery pipe may be damaged, and the protection is poor. In order to solve the above problems, we propose a leak-proof valve. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides an anti-leakage valve to solve the problems raised in the background technology.

[0007] By adopting the above technical solution, an installation component is provided to install the connecting pipe, thereby increasing the sealing of the connection with the valve body and preventing leakage during subsequent use.

[0008] Preferably, the mounting assembly comprises: two rubber rings, both of which are fixedly mounted on the outer circular wall surface of the connecting pipe, and two rubber blocks are fixedly mounted on the inner circular wall surfaces of the water inlet end and the water outlet end of the valve body, respectively, one side of the rubber block is provided with an arc-shaped clamping groove, and the inner circular wall surface of the arc-shaped clamping groove is provided with a clamping hole.

[0009] By adopting the above technical solution and setting the clamping hole, the connecting pipe can be inserted into the connecting port of the valve body during use. At this time, the connecting pipe will be squeezed into the interior of the clamping hole through the curvature of the arc-shaped clamping groove, and the outer wall of the connecting pipe will be clamped by the elasticity of the clamping hole to achieve a sealed connection effect. At this time, the rubber ring and the rubber block can be fitted together by pulling the connecting pipe backward, and at the same time, the connecting pipe can be swung. At this time, multiple protections against leakage can be achieved, thereby increasing the sealing performance.

[0010] Preferably, the mounting assembly further comprises: a plurality of side holes, wherein the plurality of side holes are provided on one side of the fixing block, bolts are provided inside the side holes, a plurality of threaded grooves are provided on the left and right ends of the valve body, the bolts are threadedly connected to the threaded grooves, threaded holes are provided on the left and right sides of the fixing block, hand screws are threadedly connected to the inner surfaces of the threaded holes, a clamping pad is provided at one end of the hand screw, a bearing is embedded in one side of the clamping pad, and the hand screw is fixedly mounted to the inner circular wall of the inner ring of the bearing.

[0011] By adopting the above technical solution, bolts are provided for threaded connection with the thread groove to install the fixing block. At the same time, the clamping pad can be driven to approach the outer wall of the connecting pipe by rotating the hand screw to limit it, thereby preventing the connecting pipe from falling off due to external pulling impact, thereby increasing practicality.

[0012] Preferably, the installation assembly further comprises: sealing pads are fixedly installed on the left and right ends of the valve body respectively, and a fitting pad is fixedly installed on one side of the fixing block.

[0013] By adopting the above technical solution, a sealing pad is provided to cooperate with the installation of the fixing block and the extrusion and fitting installation of the fitting pad, thereby increasing the sealing of the connection.

[0014] Preferably, the inner circular wall surface of the fixing block is provided with two inner grooves, a plurality of springs are fixedly installed inside the inner grooves, and a limiting pad is fixedly installed at the bottom end of the spring.

[0015] By adopting the above technical solution, a spring is provided to cooperate with a limiting pad to limit and clamp the outer wall of the connecting pipe, thereby preventing the connecting pipe from being damaged by external impact and increasing safety.

[0016] Preferably, a plurality of anti-slip strips are fixedly mounted on one side of the limiting pad.

[0017] By adopting the above technical solution and arranging the anti-slip strip, the auxiliary limiting pad can more stably fit and clamp the outer wall of the limiting connecting pipe.

[0018] In summary, the utility model mainly has the following beneficial effects:

[0019] By setting up an installation component for installing a connecting pipe, the sealing of the connection with the valve body is increased to prevent leakage during subsequent use; by setting up a clamping hole, the connecting pipe can be inserted into the connecting port of the valve body during use. At this time, the connecting pipe will be squeezed into the interior of the clamping hole through the curvature of the arc-shaped clamping groove, and the outer wall of the connecting pipe will be clamped by the elasticity of the clamping hole to achieve a sealed connection effect. At this time, the connecting pipe can be pulled backward to make the rubber ring and the rubber block fit together, and at the same time, the connecting pipe can be swung. At this time, multiple protections against leakage can be achieved to increase the sealing effect.

[0020] The fixing block is installed by arranging bolts for threaded connection with the thread groove. At the same time, the clamping pad can be driven close to the outer wall of the fitting connecting pipe by rotating the hand screw to limit it, thereby preventing the connecting pipe from falling off due to external pulling impact, thereby increasing practicality. A sealing pad is arranged to cooperate with the installation of the fixing block and the extrusion and fitting installation of the fitting pad to increase the sealing of the connection.

[0021] A spring is provided to cooperate with a limiting pad to limit and clamp the outer wall of the connecting pipe, thereby preventing the connecting pipe from being damaged by external impact and increasing safety. An anti-slip strip is provided to assist the limiting pad to more stably fit and clamp the outer wall of the limiting connecting pipe. BRIEF DESCRIPTION OF THE DRAWINGS
