Abstract
The utility model relates to a vortex assisting one-way valve, comprising a cylindrical body, wherein both the upper end and the lower end of the cylindrical body are provided with sealing rings, the cylindrical body is internally provided with a valve seat, an intermediate block and a valve ball arranged between the valve seat and the intermediate block, the valve seat is arranged near the bottom end inside the cylindrical body, the intermediate block is arranged at the upper part of the valve seat, and the bottom end of the intermediate block is provided with an inclined opening. The vortex assisting one-way valve has the advantage that: compared with common one-way valves, the vortex assisting one-way valve can firmly fix the valve ball due to the inclined opening of the intermediate block, hence, during the switching of the valve ball between an opening state and a closing state, good consistency of time interval is achieved to further improve the flow repeatability of pump; with the help of a unique backflow structure of the intermediate block, the valve ball can be closed and opened faster to lead to less and more stable backflow, thus the flow repeatability of pump can be improved and the flow is closer to theoretical value.
Description
Technical field
The utility model relates to a kind of valve, relates in particular to a kind of whirlpool power-assisted one-way valve.
Background technique
One-way valve be fluid can only one direction flow and position control valve that can not reverse flow.Its working principle, fluid enters from inlet, overcomes spring force, gravity, frictional force etc. the one-way valve valve port is opened.The liquid phase one-way valve generally uses the valve ball gravity closing to reach non-return effect, and the drawback of this method is that time of valve ball closure is long and unstable.And can perfection address this problem with solenoid valve, but cost is but very expensive, so in low this category of cost, do not consider this one-way valve.
The model utility content
Main purpose of the present utility model provides a kind of whirlpool power-assisted one-way valve, generally uses the valve ball gravity closing to reach non-return effect to overcome existing liquid phase one-way valve, long and unsettled deficiency of the time of valve ball closure.
The utility model compared with prior art has tangible advantage and beneficial effect, and by above technological scheme as can be known, in order to reach aforementioned model utility purpose, major technique of the present utility model thes contents are as follows:
A kind of whirlpool power-assisted one-way valve, comprise cylinder-shaped body, the top and bottom of described cylinder-shaped body are equipped with seal ring, the inside of described cylinder-shaped body be provided with valve seat, intermediate mass and be located at valve seat and intermediate mass between valve ball, described valve seat is located at place, the inner and close bottom of cylinder-shaped body, described intermediate mass is located at valve seat top, and is respectively equipped with main passage and subaisle along the vertical and horizontal directions on intermediate mass, and the bottom of described intermediate mass is provided with angle.
Beneficial effect described in the utility model is: compare with common one-way valve, because the angle of intermediate mass can be fixed valve ball firmly, so valve ball is changed constantly in open mode and closed state, time lag conformity is fine, thereby improves the flow repeatability of pump; The refluence structure of intermediate mass uniqueness makes valve ball closed faster; Make backflow still less, also more stable, can improve the flow repeatability of pump, and make flow more level off to theoretical value.
Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of specification, below with preferred embodiment of the present utility model and conjunction with figs. describe in detail as after.
Embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.
Description of drawings
Fig. 1 is the internal structure schematic representation of the described a kind of whirlpool power-assisted one-way valve of the utility model embodiment.
Among the figure: 1, seal ring; 2, cylinder-shaped body; 3, intermediate mass; 4, valve ball; 5, valve seat; 6, main passage; 7, subaisle; 8, angle.
Embodiment
For further setting forth the utility model is to reach technological means and the effect that predetermined model utility purpose is taked, below in conjunction with accompanying drawing and preferred embodiment, to according to a kind of multi-functional its embodiment of villa visible dialogue system, structure, feature and the effect thereof that the utility model proposes, describe in detail as after.
See also shown in Figure 1, a kind of whirlpool power-assisted one-way valve of the utility model preferred embodiment, comprise cylinder-shaped body 2, the top and bottom of described cylinder-shaped body 2 are equipped with seal ring 1, the inside of described cylinder-shaped body 2 be provided with valve seat 5, intermediate mass 3 and be located at valve seat 5 and intermediate mass 3 between valve ball 4, described valve seat 5 is located at place, cylinder-shaped body 2 inner and close bottom, described intermediate mass 3 is located at valve seat 5 tops, and be respectively equipped with main passage 6 and subaisle 7 on intermediate mass 3 along the vertical and horizontal directions, the bottom of described intermediate mass 3 is provided with angle 8.
When high pressure pump begins imbibition, the pump chamber internal pressure reduces, pressure in valve seat 5 is during greater than the pressure of valve pocket (being surrounded and comprised the zone of valve ball 4 by intermediate mass 3, cylinder-shaped body 2, valve seat 5) and valve ball 4 deadweight sums, valve ball 4 begins to move up, liquid enters from the A mouth, pass the passage that seal ring 1 passage flows into valve seat 5 and enter valve pocket, main passage 6 and subaisle 7 by intermediate mass 3 flow through.Be limited in its main passage angle by intermediate mass 3 up to valve ball 4, its main passage is shut, liquid can only flow into the main passage by subaisle, and seal ring 1 enters pump chamber from the B mouth above passing.One-way valve is on state with this rock-steady structure afterwards.
When high pressure pump begins discharge opeing, this moment, the pump chamber internal pressure was little, so be not enough to open the one-way valve of the other end, this moment, pump chamber remained static, liquid can not flow out in pump chamber, thus also should be static, but because liquid inertia, liquid that can not is at once static, but discharges the energy of savings by the form of whirlpool.And broad more cavity whirlpool is fierce more, and narrow more cavity liquid is fast more static.So when liquid passes through intermediate mass 3 subaisles, intermediate mass 3 main passages are very fast static to the very long one section ducted liquid of crack of pump chamber, and it is passless to make progress, so liquid begins to dirty, rush at valve ball 4, valve ball 4 is moved down rapidly and with the valve seat closure.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, though the utility model discloses as above with preferred embodiment, yet be not in order to limit the utility model, any those skilled in the art, in not breaking away from the technical solutions of the utility model scope, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be the content that does not break away from technical solutions of the utility model, according to technical spirit of the present utility model to any simple modification that above embodiment did, equivalent variations and modification all still belong in the scope of technical solutions of the utility model.
