Description
Technical field
The present invention relates to multifunctional non-return valve core, particularly a kind of non-return valve core that can be directly installed on any valve and any inner cavity of pipe.
Background technique
Common valve only has unlatching, closes the function of fluid flow, wants to make fluid to flow backwards, and a safety check must be set match with it.Traditional safety check generally is fixed together with pipeline by being threaded and forms a complete safety check, must carry out screw thread processing to connecting tube when mounted, thereby reduce working efficiency.The conventional check valves structure generally is to adopt a dish spring or flap, its working principle is a flap of settling in the central to be expressed to realize the non-return sealing on the valve seat, conventional check valves is when opening, the fluid that flows around the valve closed shape will make this valve closed shape encourage on stroke moving direction or shake, will cause the fluid flow amount that undesirable fluctuation takes place like this, and then cause the additional power load of dish spring or flap and cause hydrodynamic noise, working life that also can reduction dish spring simultaneously, poor safety performance, the cost height, replacing is difficult for, and the installation randomness is not strong.
Summary of the invention
The object of the present invention is to provide a kind of multifunctional non-return valve core, need not that when mounted pipeline and valve are carried out screw thread processing and can realize connecting, have install random strong, Safety performance is good, cost is low, change easily the characteristics of stability of flow, long service life.
For achieving the above object, the present invention is by the following technical solutions:
A kind of multifunctional non-return valve core is made up of helical pitch seat, helical pitch support, spool and dish spring, helical pitch seat and helical pitch support engagement connection, and both joints are provided with a seal washer; The dish spring is arranged between spool and the helical pitch support, and it is characterized in that: helical pitch support afterbody is provided with a boss, is connected by a plurality of stiffening ribs between boss and the rack body; The boss inner hollow, its bottom is provided with a helical pitch track; Spool is beveled structure, and its afterbody is built in the helical pitch track, and its head holds on seal washer under the effect of compact disk spring; Helical pitch seat outer side wall is provided with a round section joint ring, and helical pitch support outer side wall is provided with a plurality of elasticity clamping close devices.
Above-mentioned elasticity snap-in structure becomes circumference evenly to distribute around helical pitch support outer side wall.
Above-mentioned helical pitch seat, helical pitch support and spool are made by plastic materials, also can adopt metallic material to make.
The present invention utilizes the elasticity snap-in structure of helical pitch support outer side wall setting to be stuck in the groove of pipeline and valve (below abbreviate valve as) inner chamber when mounted, need not to carry out screw thread processing, directly utilize the static friction of elasticity snap-in structure and inner cavity of pipe and valve cavity sidewall to realize being connected, safety check that makes and pipeline and valve become one, and realize both sealings by the round section joint ring of helical pitch seat outer side wall setting, simplify installation steps greatly, improved working efficiency.Spool is beveled structure, its afterbody is built in the helical pitch track on the helical pitch support, thereby limited the range of movement of spool, excitation or concussion take place in spool when having avoided fluid to flow through safety check on stroke moving direction, make the fluid flow amount stable, the additional power load of dish spring keeps substantially constant, has reduced hydrodynamic noise to a certain extent, and prolonged the working life of dish spring greatly.

Embodiment
Multifunctional non-return valve core shown in Fig. 1,2,3,4 and 5, form by helical pitch seat 1, helical pitch support 2, spool 3 and dish spring 4, helical pitch seat 1 and helical pitch support 2 engagement connections, both joints are provided with a seal washer 5, wherein the internal diameter of seal washer 5 less than helical pitch seat 1 greater than helical pitch support 2.Helical pitch support 2 afterbodys are provided with a boss 21, are connected by three stiffening ribs 22 between boss 21 and helical pitch support 2 bodies, and boss 21 inner hollow, its bottom is provided with a helical pitch track 211.Spool 3 is beveled structure, its afterbody is built in 211 li on helical pitch track, spool 3 heads become a umbrella shape, and its maximum diameter is slightly larger than seal washer 5, hold on seal washer 5 under the effect that is arranged on compact disk spring 4 restoring forces between spool 3 and the helical pitch support 2.Adopt such structure, because of spool 3 afterbodys are built in 211 li on helical pitch track on the helical pitch support 2, thereby limited the range of movement of spool 3, excitation or concussion take place in spool 3 when having avoided fluid to flow through safety check on stroke moving direction, make the fluid flow amount stable, the additional power load of dish spring 4 keeps substantially constant, has reduced hydrodynamic noise to a certain extent, and prolonged the working life of dish spring 4 greatly.
Helical pitch seat outer side wall is provided with a round section joint ring 6, and helical pitch support 2 afterbody outer side walls are provided with a plurality of elasticity clamping close devices 23, adopts six in the present embodiment, and its rich helical pitch support 2 outer side walls become circumference evenly to distribute.When mounted, utilize the elasticity snap-in structure 23 of helical pitch support 2 outer side wall settings to be stuck in the groove of valve cavity, need not to carry out screw thread processing, directly utilize the elasticity snap-in structure 23 and the static friction realization of valve cavity sidewall to be connected, and the round section joint ring 6 that passes through the setting of helical pitch seat 1 outer side wall is realized both sealings, thereby simplified installation steps greatly, improved working efficiency.Simultaneously, such structure organically becomes one safety check and valve, makes common valve having unlatching, closing outside the effect of fluid flow, also has the specific function that fluid can not be flow backwards of safety check.
When opening that valve switch is opened or during fluid flow, spool 3 is backed down, its umbrella shape head and seal washer 5 break away from, and are compressed the pipeline conducting with hour indicator spring 4; When valve switch is closed or fluid when not circulating, spool 3 returns to initial position rapidly under the effect of compact disk spring 4 restoring forces and reflux fluid pressure, and make umbrella shape head and seal washer 5 holding together tightly, thereby realize the function that the safety check fluid can not flow backwards.
The present invention can directly be connected with valve cavity with inner cavity of pipe.In addition, the helical pitch seat 1 among the present invention, helical pitch support 2 and spool 3 are made by plastic materials or metallic material, advantage such as have reliability, flexibility, cost is low, anticorrosion ability is good.In a word, the present invention need not that when mounted pipeline is carried out screw thread processing and can realize connecting, and has the characteristics of easy for installation, stability of flow, long service life.
