Abstract
The utility model relates to a take plug screw of sealing washer has solved the plug screw of current sealed effect and plug screw seat cooperation assembly when installing inconvenient, spare part easily loses and neglected loading, can't guarantee defects such as accuracy and reliability of assembly. The utility model discloses a plug screw that comprises flange portion, polished rod portion and screw thread portion, polished rod portion has overlapped the sealing washer. The utility model discloses simple structure, guaranteed the exactness and the reliable performance of assembly, stopped and dismantled and the risk that O type sealing washer lost or neglected loading in the installation, also reduced the work load of dismouting in-process simultaneously, sealed effectual, with the cooperation of plug screw seat, need on the spare part body of sealed processing in being suitable for each trade.
Description
Technical field
The utility model relates to a kind of seal fitting, specifically a kind of plug screw that has seal ring of being convenient to the component assembling and guaranteeing sealability.
Background technique
The sealing of existing hole structure normally adopts the installation of plug screw seat, pre-gelatinized plug screw and O RunddichtringO to guarantee its sealability.During assembling, the plug screw seat is welded on the concave station place that places plug screw seat endoporus correspondence on the hole of body of component, with the O RunddichtringO, then the screw section of pre-gelatinized plug screw is screwed in the plug screw seat, internal thread cooperates the mode of tightening with screw thread that the O RunddichtringO is compressed to get final product in the plug screw seat with the outside thread of plug screw.The shortcoming that this seal style exists is: (1) seal ring needs to install separately, easily the O RunddichtringO is lost or neglected loading when the repeated disassembled and assembled plug screw, thereby is caused seal failure; (2) after each sealing all needs concave station with O RunddichtringO aligning plug screw seat to place, insert plug screw again and tighten, the installation procedure complexity wastes time and energy.
Summary of the invention
The purpose of this utility model is provide at above-mentioned deficiency a kind of simple in structure, convenient for assembly, time saving and energy saving, guarantee not lose in reliable usability, the disassembly process or the plug screw that has seal ring of neglected loading component.
The utility model is achieved in that the plug screw that has seal ring, comprises the plug screw that is made of flange part, polished rod portion and screw section, and described polished rod portion is with seal ring.
The internal diameter size of described seal ring is greater than the outside dimension of polished rod portion and less than the outside dimension of screw section.
Described seal ring can be preferably the O RunddichtringO for various seal ring commonly used.
Because when plug screw and plug screw seat are tightened, the polished rod portion of the plug screw just in time concave station with the plug screw seat is corresponding, therefore, consideration is the suit seal ring in polished rod portion, and utilize the characteristics of polished rod portion outside dimension less than the screw section outside dimension, the internal diameter of seal ring is designed to greater than the external diameter of polished rod portion and less than the size of the external diameter of screw section, both can have avoided internal diameter of the seal ring excessive by deviating from the plug screw, also avoided the internal diameter of the seal ring tension by the corner wear problems of square thread down.
Advantage of the present utility model:
1, under the situation that guarantees associated component structural, size constancy, ring set becomes the part of plug screw in polished rod portion, so both made repeated multiple times from the plug screw seat during the dismounting plug screw, can not occur that seal ring is lost or neglected loading yet, thereby avoid the problem of seal failure, guaranteed the reliability of correctness, convenience and the usability of assembling.
2, during installation, need not on the plug screw seat, to be provided with earlier separately seal ring, but directly plug screw is inserted in the plug screw seat, utilize internal and external threads to tighten and get final product, tighten when pressing down, the seal ring of polished rod portion can be positioned at the corresponding concave station place of plug screw seat just, reduced the step of placing seal ring, time saving and energy saving, good sealing effect.
3, the utility model relates to and can be used for the sealing part that every profession and trade needs plug screw and plug screw seat to be used, good sealing effect.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the mounting structure schematic representation of the utility model and plug screw seat.
Among the figure: 1-component body, 1.1-endoporus, 2-plug screw, 2.1-flange part, 2.2-polished rod portion, 2.3-screw section, 3-O RunddichtringO, 4-plug screw seat, 4.1-endoporus, 4.2-concave station.
Embodiment
Below in conjunction with drawings and Examples the utility model is further explained explanation:
With reference to Fig. 1, plug screw 2 comprises flange part 2.1, polished rod portion 2.2 and screw section 2.3, wherein is with O RunddichtringO 3 in the polished rod portion 2.2, and the internal diameter size of described O RunddichtringO 3 is greater than the outside dimension of polished rod portion 2.1 and less than the outside dimension of screw section 2.3.
With reference to Fig. 2, during assembling, plug screw seat 4 endoporus 1.1 direct and component body 1 weld together the internal thread that plug screw seat 4 endoporus 4.1 are got on the bus and can be cooperated with plug screw 2 outside threads.When needs seal, plug screw 2 is directly inserted the endoporus 4.1 of plug screw seat 4, rotate plug screw 2 then, the outside thread of plug screw 2 and the screw-internal thread fit of plug screw seat 4 are tightened, O RunddichtringO 3 is displaced downwardly to concave station 4.2 places and compacted thereupon, thereby reach seal action, its sealing effect mounting structure compared with before-improvement will be got well, stopped that O RunddichtringO 3 in dismounting and the installation process is lost or the risk of neglected loading, also reduced simultaneously the workload in the disassembly process, main is the reliability that has guaranteed correctness, convenience and the usability of assembling.
