Abstract
The present invention relates to the improvement on a prefill valve mechanism, particularly to the improvement on an installation structure of a ventiduct on a prefill valve assembly. The prefill valve assembly comprises cylindrical retainer which downwards extends from the lower end of a liquid valve rod. A plurality of round balls which can rotate are buried at intervals on the same circumference at the inner side of the retainer. The retainer is provided with concave bases, the number of which is the same as the number of the round balls. The round balls can be placed into the concave bases in a rotatable way and keep certain gaps with the concave bases so that the round balls can move on the circumference of the retainer.
Description
This patent is about can be used for the prefill valve of liquid-filling valve.
Fig. 5 is a kind of longitudinal diagram of original prefill valve 1.Its right-hand part represents that valve is in opening.The left side represents that valve is in closure state.Breather pipe 2 is to be connected on the liquid valve rod 5 by screw 4.The 3rd, the liquid valve seal strip of making by elastomeric material, the 6th, the O shape ring of the sealing usefulness of making by elastomeric material.The bottle of can recently and the kind of liquid increase, and for adapting to this trend, require often to change breather pipe 2; But fixing very time-consuming with screw, change 40～60 times in second of needs, so very undesirable from production efficiency.
The problem to be solved in the present invention is exactly the low problem of original technology production efficiency; A kind of prefill valve promptly is provided, does not need instrument just can change breather pipe at short notice, can not transfer to even pull at also after loading onto.
The present invention is exactly: at the tubular valve body that is formed by the liquid that is vertically mounted on charging device valve seat cashier's office in a shop, insert in the prefill valve of the valve body in the valve body tubular liquid valve rod that forms and detachable threes such as the breather pipe formation that is installed in liquid valve rod lower end, insert barrel-contoured retainer from the lower end of above-mentioned liquid valve rod, and on the same circumference of retainer inboard, equally spaced bury and be placed with some balls that can rotate, ball is side-prominent in the retainer, upper end edge at above-mentioned breather pipe axially processes a groove, the depth ratio ball outshot of groove is big slightly, groove is crooked and diminish along circumferencial direction in the end, loads onto the O shape ring that is used for sealing gap between breather pipe and the retainer at ball upper-lower position place.
Below by figure explanation embodiments of the invention; Fig. 1～Fig. 4 represents embodiments of the invention.In Fig. 1～Fig. 4, the 11st, valve body, the 12nd, breather pipe, the 3rd, valve seat insert, 13 and 14 is O shape rings of being made by elastomeric material, the 15th, ball, the 16th, keep the retainer of ball position, the 17th, the O shape ring that elastomeric material is made, the 18th, the close blind groove of receiving ball 15, the 19th, for inserting the guide groove of the ball 15 that breather pipe 12 is provided with, the 20th, liquid valve rod.Breather pipe 12 usefulness screw threads are connected with liquid valve rod 20.
Have the horizontal slot that the coupled degree of depth is g in addition in the lower end of guide groove 19, process the end 18a of groove at the horizontal slot end.The degree of depth g of groove 18 is darker slightly than the outstanding size e of ball 15.When breather pipe 12 being rotated to the ball 15 that makes in the retainer 16 when entering into the end 18a of groove 18, it is good that breather pipe is just inserted.Owing to adopted this ball 15 that remains in the retainer 16, so needn't just can transfer to breather pipe 12 with speciality tool; Simultaneously because hole 16a, the horizontal slot 18 and the ball overhang e of breather pipe 12 of retainer 16 play effect effectively, so can prevent fully that breather pipe 12 from coming off.
In the above-described embodiments, used 3 balls 15, in fact the quantity of ball 15 all is fine as long as surpass 2.Horizontal slot 18 only is level in the above-described embodiments, but comes off in order to prevent, after the terminal of groove 18 processes horizontal termination, processes by groove above groove 18 terminals.Can breather pipe more effectively be remained in the retainer 16 as breather pipe 12 modes of leaving behind like this.
Below at length introduced structure of the present invention; Compare with original structure, it is greatly convenient to install and remove.
Adopt oldfashioned quick connector mode as breather pipe, then will strengthen the amount of movement of ball, outer sleeve can at will be slided; As adopting spring return mode, ball can not drop yet when outer sleeve was descended.Therefore structure is very complicated, just can load onto, pull down with two hands.Structurally also can't do like this prefill valve.
The present invention has adopted the ball locate mode, prevents the breather pipe swing, no odd parts, just can load onto, pull down with a hand, simultaneously can confirm to have installed to certain position, because the fastening force effect of two O shape rings up and down can prevent to insert good breather pipe in running condition rotation, come off.
Simple declaration to figure
Fig. 1 is the longitudinal diagram of prefill valve of the expression embodiment of the invention, and Fig. 2 is the drawing in side sectional elevation of its breather pipe, and Fig. 3 is the sectional side view of its breather pipe, and Fig. 4 is that drawing in side sectional elevation is amplified in the part in hole on the retainer, and Fig. 5 is a kind of longitudinal diagram of old prefill valve.
The explanation of main portion among the figure

Claims (3)
1, a kind of prefill valve comprises that one is vertically mounted on the liquid tubular valve body that has a valve seat cashier's office in a shop of charging device, one is contained in the detachable breather pipe that the interior tubular liquid valve rod and of valve body is installed in liquid valve rod lower end, it is characterized in that being equipped with a tubular retainer in the lower end of described liquid valve rod, uniformly-spaced be provided with many balls on the inner peripheral surface of retainer rotationally, these balls are radially outstanding from the inner peripheral surface of retainer; The upper end of described breather pipe offers and the corresponding groove of ball, the degree of depth of these grooves is slightly larger than the inside overhang in footpath of ball, each described groove all changes an elbow bend after the longitudinally of breather pipe extends one section, along circumferentially extending, be reduced to zero in the end of circumferential slot section groove depth then.
2, prefill valve as claimed in claim 1 is characterized in that described ball has two at least.
3, prefill valve as claimed in claim 1 or 2 is characterized in that being equipped with the O shape that seals in the above and below of described ball encircles.
