Accompanying drawing explanation
Also will be described in more detail the present invention with reference to accompanying drawing based on embodiment hereinafter.In the drawings:
Fig. 1 is the structural representation of float collar of the present invention.
In the accompanying drawings, identical parts use identical Reference numeral.Accompanying drawing is not according to the scaling of reality.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
Float collar of the present invention can be float-ball type float collar, can be also brace type float collar, Figure 1 shows that brace type float collar.It comprises shell 1, valve 5, valve seat 2 and the gaily decorated basket 4.Wherein, the gaily decorated basket 4 is arranged in shell 1 regularly.Valve 5 is arranged in the gaily decorated basket 4, and can contact with valve seat 2.Valve seat 2 is located in shell 1 and also and between the inwall of shell 1 leaves gap.Be filled with in gap and at high temperature can flow, and can solidify at normal temperatures, and solidify rear on-deformable shaping material 3.Those skilled in the art easily specifically determine to select which kind of shaping material 3 according to requirements.
Valve seat 2 is connected with shell 1 by this shaping material 3.Like this, the degree of being connected firmly between valve seat 2 and shell 1 can be improved, and then improve the application life of float collar.In addition, when the shape of shell 1 be restricted be not easy to change time, it can be made to form gap between the two by the diameter reducing valve seat 2.Therefore, this kind of connected mode goes for multiple float collar.
Because cast aluminium uses more, shaping material 3 is therefore preferentially selected to be cast aluminium.In addition, after cast aluminium solidifies, and adhesion strength between shell 1 or valve seat 2 is higher, can improve the degree of being connected firmly between valve seat 2 and shell 1 further.
In the use procedure of float collar, because the Impact direction of valve seat 2 is identical with the axis direction of shell 1, therefore preferentially select and be defined for the gap of filling shaping material 3 by the sidewall of the sidewall of valve seat 2 and shell 1.Like this, the degree of being connected firmly between valve seat 2 and shell 1 can be increased further.And this set can also prevent shaping material 3 from blocking flow liquid passage on valve seat 2.
In addition, valve seat 2 with shell 1 can be respectively equipped with multiple groove 6 be communicated with gap, to increase the degree of being connected firmly between valve seat 2 and shell 1 further.When gap is limited by the sidewall of valve seat 2 and the sidewall of shell 1, groove 6 is also positioned on the sidewall of valve seat 2 and shell 1, can be communicated with gap, thus shaping material 3 is filled in groove 6.
Preferably, the bearing of trend of groove 6 and the axis direction of shell 1 perpendicular.Like this, effectively can prevent shaping material 3 from coming off from gap, the degree of being connected firmly of valve seat 2 and shell 1 can be increased further.Meanwhile, the application life of float collar can also be improved.Further, the groove 6 of valve seat 2 is relative with the groove 6 of shell 1.Like this, shaping material 3 can be increased perpendicular to the thickness on shell 1 axis direction, and then increase it by force intensity.
In addition, when liquid stream is through float collar, need to open valve 5 by the impact force of liquid, and when liquid flows into float collar, certain impact force is also had to valve seat 2, thus make valve seat 2 stressed maximum in the position of the inlet near float collar.Therefore, when valve seat 2 and shell 1 are provided with multiple groove 6, the degree of depth of each groove 6 reduces along the inlet of float collar gradually to liquid outlet direction.By such setting, stressed at inlet of shaping material 3 can be increased, thus the degree of being connected firmly of valve seat 2 and shell 1 can be improved further.
When needs package shell 1 and valve seat 2, first shell 1 is placed on pedestal, and the liquid outlet one end making shell 1 upward.Then press on shell 1 by valve seat 2, during to prevent from filling shaping material 3, shaping material 3 enters flow liquid passage from the gap between the end and shell 1 of valve seat 2, and then blocking flow liquid passage.Last again to the shaping material 3 of filled high-temperature in gap, and place a period of time at normal temperatures, until solidify.
When filling shaping material 3 in gap, shaping material 3 can be made to fill the full gap limited by the sidewall of valve seat 2 and the sidewall in outside.That is, the height of shaping material 3 equals the height of valve seat 2.Like this, its degree of being connected firmly can be increased further.
The gaily decorated basket 4 can directly be threaded with shell 1, also can be threaded with valve seat 2.Preferentially select herein and be threaded with valve seat 2, to increase the application scenario of float collar.After assembling the gaily decorated basket 4 and valve seat 2, then to gap-fill shaping material 3.Now, the height of shaping material 3 higher than the height of valve seat 2, can flood the coupling part of the gaily decorated basket 4 and valve seat 2.Like this, the degree of being connected firmly of the gaily decorated basket 4 and valve seat 2 can be improved.In addition, can also arrange on shell one with the gaily decorated basket 4 and valve seat 2 contact the relative groove of end face 6, to improve the degree of being connected firmly of the gaily decorated basket 4 and valve seat 2 further.
Although invention has been described with reference to preferred embodiment, without departing from the scope of the invention, various improvement can be carried out to it and parts wherein can be replaced with equivalent.Especially, only otherwise there is structural hazard, the every technical characteristic mentioned in each embodiment all can combine in any way.The present invention is not limited to specific embodiment disclosed in literary composition, but comprises all technical schemes fallen in the scope of claim.
