Specific implementation mode
In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, below in conjunction with the accompanying drawings to the present invention
Specific implementation mode be described in detail.
It please refers to Fig.2 to Fig. 5, the present invention provides a kind of check valve assembly, including a combined pipe 100 and positioned at described
In combined pipe 100 and the elastic parts and plug 300 that are disposed adjacent, the plug 300 is close to one end of the elastic parts
It is equal to the plug pedestal 310 of maximum gauge in the combined pipe 100 for diameter, one end far from the elastic parts is plug
Ontology 320 docks place in the combined pipe 100 with the plug ontology 320 and is defined as water inlet line, with the plug sheet
The docking place of body 320 is that size matches place with 320 size of plug ontology in water inlet line.
Specifically, Fig. 3 is please referred to, in the present embodiment, combined pipe 100 includes upper body 110 and lower body successively
120, one end that the upper body 110 is threaded in the lower body 120 makes the pipeline inside the two be connected to this knots of
Structure is embodied in the present embodiment：Upper body 110 is a boring pipeline, is extended to form to 120 one end of lower body
Have a upper body inner tube 111,111 periphery of upper body inner tube is provided with upper body inner tube external screw thread 112, lower body 120 with upper
Internal pipe external screw thread 112 corresponds to place and is also provided with corresponding internal thread so that upper body inner tube 111 is fixed by screw thread rotation
In lower body 120.
It is more than the part of upper body inner tube 111 with internal diameter in lower body 120, elastic parts and plug 300 are located at should
In part, in end of the elastic parts far from plug 300, the internal diameter inside lower body 120 at this, which is progressively smaller until, to be less than
The maximum width of elastic parts.Specifically, in the present embodiment, elastic parts is specially in spring 200 namely lower body 120
Internal diameter at this is gradually reduced to less than the diameter of spring 200, so that 200 one end of spring resists 120 inner wall of lower body, separately
One end can resist plug 300, so as to give 300 thrust of plug.
Preferably, please continue to refer to Fig. 3, it is provided on the plug pedestal 310 towards the elastic parts direction and is extended
Limit grid 330,100 axial direction of length direction and the combined pipe of limit grid 330 is parallel, specifically, the limit
Grid 330 be around the equally distributed limited post 331 of 310 central shaft of plug pedestal, in the present embodiment, limited post 331 formed
Cylinder outer diameter is slightly less than spring 200, and above-mentioned limited post 331 stretches into spring 200 so that spring 200 keeps same with plug pedestal 310
Axis, so that 310 uniform force of plug pedestal.
Correspondingly, uniform in order to keep the thrust of spring 200 to transmit, plug ontology 320 is also co-axially located at plug pedestal
Corresponding with upper body inner tube 111 on 310, the direction of motion is also axial parallel with upper body inner tube 111.
Also, in the present embodiment, plug ontology 320 is in bullet shape or round table-like, and maximum outside diameter is equal to upper
The internal diameter of ontology inner tube 111, but less than the diameter of plug pedestal 310.If plug ontology 320 is in a circular table shape, in the upper body
Pipe 111 docked with the plug ontology 320 place shape be also configured to match with plug ontology 320 it is round table-like；Work as plug
When ontology 320 is bullet shape, upper body inner tube 111 seeps water in order to prevent it is not necessary that specific shape is arranged, need to be stifled
It is arranged sealing ring on head ontology 320.
Based on the internal structure of above-mentioned check valve assembly, check valve assembly inner working principle is：Fig. 4 is please referred to, water is worked as
Stream direction is when flowing to upper body 110 from lower body 120, plug pedestal 310 by the elongation of spring 200 thrust and flow
Pressure so that plug ontology 320 enters in upper body inner tube 111, and in the present embodiment, plug ontology 320 enters in upper body
In pipe 111, since plug ontology 320 docks place shape matching with upper body inner tube 111, and the diameter of plug pedestal 310 is big
In the diameter of plug ontology 320 so that plug ontology 320 enters in upper body inner tube 111, causes plug 300 will be in upper body
Pipe 111 blocks, and flow cannot be introduced into upper body inner tube 111, and check valve is closed；Please refer to Fig. 5, when water (flow) direction from
When upper body 110 flows to lower body 120, plug 300 is by water flow pressure at upper body 110 at this time, to lower body 120 at move
Dynamic, 300 other side of plug is resisted by spring 200, and when water flow pressure is more than the convergent force of spring 200, spring 200 starts to receive
Contracting, plug ontology 320 leave upper body inner tube 111, form the gap that water supply stream passes through between the two, unidirectional valve body is since then
Conducting.
Preferably, side of the lower body 120 far from upper body 110 has also extended to form lower body inner tube 121, that is, on
It states in place of 120 internal diameter of lower body is gradually reduced and continues to extend to form lower body inner tube 121 in this direction, the lower body inner tube
Lower body inner tube external screw thread 122 is also equipped on 121 excircles, similarly, upper body inner tube 111 is far from lower body 120
End also forms external screw thread, and lock nut 400 is arranged at this.
Check valve assembly provided by the invention only needs combined pipe 100, elastic parts and 300 3 kinds of structures of plug mutual
Cooperation integrates the direction of the power generated to plug 300 to determine plug ontology by the contractility and water flow pressure of elastic parts
Whether 320 enter in water inlet line, and to determine the conducting and closing of check valve, this structure is relatively simple, occupies volume
Small, production and installation are all relatively simple, reduce production and application cost.
Obviously, those skilled in the art can carry out invention spirit of the various modification and variations without departing from the present invention
And range.If these modifications and changes of the present invention is within the scope of the claims of the present invention and its equivalent technology, this
Invention is also intended to including these modification and variations.
