Description

Technical Field

[0001] The utility model relates to the technical field of one-way valve installation structures, in particular to an inverted liquid-taking one-way valve. Background Art

[0002] When a traditional one-way valve is installed upside down, holes need to be drilled in the valve body so that the valve body can be installed on the external equipment with bolts. However, the drilling method may cause damage to the valve body, and even cause additional overflow points on the valve body due to the depth and accuracy of the drilling. At the same time, it is affected by the installation space and installation method, making the bolt installation more cumbersome and complicated. That is, there is less gap between the valve body and the external equipment, which makes it inconvenient to install the bolts. At the same time, the installation bolts need to be frequently removed for later maintenance or disassembly. The entire disassembly and assembly is more complicated and cumbersome, and frequent disassembly and assembly affects the coaxiality between the valve body and other connected equipment. Utility Model Content

[0005] The above technical solution is beneficial in that: before installing the valve body, the base is installed on the external equipment or tooling, that is, the base is installed on the external equipment or tooling through the mounting member, and then the valve body is inserted into the groove along the opening direction of the base. When the valve body is inserted into the groove, the valve body is initially limited and fixed in the groove by the limiting structure. After the valve body is initially fixed, the valve body is fixed in the groove by the linkage cooperation of the limiting member and the mounting member, thereby preventing the valve body from falling out of the groove along the height direction of the base, thereby achieving the fixation of the valve body in the base, and then the load is applied to the valve body by the cooperation of the loading member and the limiting member. In this way, the valve body is fixed in the groove, and shaking or loosening of the valve body in the groove is avoided, thereby preventing the coaxiality between the valve body and other connecting equipment or pipelines from being affected. The above-mentioned technical setting can realize rapid disassembly and assembly of the valve body, and at the same time, the valve body can be fixed without drilling holes or screwing in bolts on the valve body. In the later stage, when disassembly or maintenance is required, there is no need to remove the base, and the valve body can be disassembled and assembled by only removing the valve body. At the same time, the base does not need to be removed, so that when the valve body is installed, it can be quickly aligned with the coaxiality of other external connecting equipment or pipelines to ensure coaxiality, thereby improving disassembly and assembly efficiency.

[0006] The utility model is further provided with: the mounting part includes two wing plates arranged opposite to each other, the two wing plates are respectively arranged on the two side walls of the base, a plurality of mounting holes are opened on the wing plates, and each of the mounting holes is threadedly connected with a mounting bolt for threaded cooperation with the embedded hole on the external tooling.

[0007] The benefit of adopting the above technical solution is that: when installing the base, the wing plate is flush with the outer wall of the external device, so that the mounting hole is coaxially aligned with the embedded hole on the external device, and then the mounting bolt is screwed in to fix the wing plate, thereby fixing the base on the external device.

[0008] The present invention is further provided with: two groups of limiting parts are arranged on both sides of the base, and the limiting parts include a horizontal plate, a vertical plate and a limiting plate. The horizontal plate and the vertical plate are perpendicular to each other and connected, and the limiting plate and the vertical plate are perpendicular to each other and connected. The horizontal plate and the limiting plate are arranged in parallel, and the horizontal plate is fitted with adjacent wing plates and the horizontal plate is provided with connecting holes corresponding to each adjacent mounting hole position, and each connecting hole is threadedly matched with the mounting bolt in the corresponding mounting hole, the vertical plate is fitted with the side wall of the base, and the inner wall surface of the limiting plate is a limiting surface for locally abutting against the bottom wall of the valve body.

[0009] The advantages of adopting the above technical solution are: before the base is fixed, the cross plate and the wing plate are leveled so that the connecting hole and the mounting hole are coaxially aligned, and then the mounting bolts can be screwed in to achieve the connection and fixation between the cross plate, the wing plate and the external equipment, thereby achieving the fixation of the cross plate. Before the cross plate is fixed, the vertical plate is in contact with the side wall of the base, and the limit plate is arranged parallel to the cross plate, so that after the valve body is placed in the groove, the limiting surface of the limit plate can partially abut against the bottom wall of the valve body to achieve the limitation and support of the valve body, and then achieve the positioning and fixation of the valve body, and prevent the valve body from falling out of the groove along the height direction of the base; in the above technology, the clearance fit or fit between the cross plate and the wing plate can be achieved by adjusting the screw-in distance of the mounting bolts, so as to achieve the adjustment of the limit plate along the height direction of the base, and then adapt to valve bodies of different heights, ensuring that the limiting surface of the limit plate always abuts against the bottom wall of the valve body, thereby improving the adaptability range and practicality.

[0010] The utility model is further provided with: a plurality of loading holes are opened on the limit plate, loading bolts are threadedly connected in the loading holes, the ends of the loading bolts are loading ends for abutting and cooperating with the side walls of the valve body, and the loading bolts are loading parts.

[0011] The benefit of adopting the above technical solution is that: after the cross plate is fixed, the loading end is abutted against the side wall of the valve body by screwing the loading bolt into the loading hole. Since loading bolts are provided on both sides of the valve body, the clamping and limiting of the valve body can be achieved by a combination of several loading bolts, thereby achieving the fixation of the valve body in the receiving groove, thereby avoiding shaking or loosening of the valve body in the receiving groove, thereby ensuring that the coaxiality of the valve body and the connection strength between the valve body and the external connection equipment or pipeline will not be affected.

[0012] The present invention is further provided with an expansion pad on the loading end for expansion-fitting with the side wall of the valve body, and the expansion pad is made of elastic rubber material.

[0013] The benefit of adopting the above technical solution is that the expansion pad is provided in the above technology to ensure that the outer peripheral wall of the valve body is not affected when the loading shaft applies load to the valve body, thereby avoiding damage to the valve body.

[0014] The present invention is further provided with: plug-in blocks protruding from both side walls of the valve body along the direction in which the receiving groove is opened; the limiting structure includes slots respectively arranged on the inner walls on both sides of the receiving groove; the two ends of the slots are respectively connected to two sockets; the two plug-in blocks are respectively plugged into and matched with the two slots; the radial cross-section of the plug-in blocks is trapezoidal; the radial cross-section of the slots is adapted to match the radial cross-section of the plug-in blocks.

[0015] The benefits of adopting the above technical solution are: the initial limitation and fixation of the valve body in the receiving groove are achieved through the plug-in cooperation of the plug-in block and the slot, so as to realize the rapid disassembly and assembly of the valve body. At the same time, the radial cross-section of the plug-in block is set to be trapezoidal, and the radial cross-section of the slot is adapted to the radial cross-section of the plug-in block, so as to realize the rapid plug-in of the plug-in block and the slot and prevent the valve body from slipping, shaking or loosening along the height direction of the base, thereby improving the connection strength between the valve body and the base.
