Referring to fig. 1-4, a fluid transfer valve 100 of the present invention includes a valve body 110 and a sealing skirt 120.
The valve body 110 has a fluid inlet 110a, a fluid outlet 110b, and a fluid passage 110c communicating the fluid inlet 110a and the fluid outlet 110 b.
Wherein the sealing skirt 120 is capable of obstructing the flow of fluid from the fluid outlet to obstruct the flow of fluid to the exterior of the fluid transfer valve 100, i.e., the sealing skirt 120 is configured to obstruct the flow of fluid from the fluid outlet 110b, e.g., when the fluid pressure is not sufficient to flush the sealing skirt 120, the fluid from the fluid outlet cannot flow to the exterior of the fluid transfer valve 100 through the sealing skirt 120.
The shape of the valve body 110 is various, and the shape of the valve body 110 may be a square shape, a circular shape, or other shapes of the valve body 110, and is not limited in detail herein. The fluid inlet 110a and the fluid outlet 110b may be located on the same side or different sides of the valve body 110, and fig. 4 shows the fluid inlet 110a and the fluid outlet 110b located on opposite sides of the valve body 110.
The number of the fluid inlets 110a and the number of the fluid outlets 110b may be one or more, and the number of the fluid inlets 110a and the number of the fluid outlets 110b are at least two, and similarly, the number of the fluid channels 110c may be one or more, the fluid channels 110c and the fluid inlets 110a may be arranged in a one-to-one manner, the fluid channels 110c and the fluid inlets 110a may be arranged in a one-to-many manner, and the corresponding relationship between the fluid channels 110c and the fluid outlets 110b is set by referring to the corresponding relationship between the fluid channels 110c and the fluid inlets 110 a; when the fluid channel 110c is multiple, the number of the fluid inlets 110a and the number of the fluid outlets 110b corresponding to each fluid channel 110c may be the same or different, and are not limited herein.
The sealing skirt 120 extends from the outer peripheral wall of the valve body 110 adjacent to the fluid outlet 110b in a direction away from the valve body 110, a protrusion 121 extending along the circumferential direction of the sealing skirt 120 is provided in the inner wall of the sealing skirt 120 at a position away from the valve body 110, and the protrusion 121 may be provided in a closed loop.
By way of example and not limitation, the sealing skirt 120 is flared to have a first end and a second end, the first end having a smaller diameter than the second end, and the first end is connected to the fluid outlet 110b of the valve body 110, such that the sealing fluid effect is enhanced, i.e., the fluid is prevented from flowing to the exterior of the fluid transfer valve, thereby facilitating the control of the flow of the liquid from the fluid outlet.
The shape of the protrusion 121 may be various, and the shape of the protrusion 121 may be a regular shape, such as a circular ring shape, a square ring shape, or an elliptical ring shape, or the shape of the protrusion 121 may be an irregular shape, which is not limited herein. Fig. 1 shows a case where the projection 121 has an annular shape. The axial length of the protrusion 121 may be 3mm, 4mm, 5mm, and other length values, and the width of the protrusion 121 may be 2mm, 3mm, 4mm, and other width values, which are not limited herein.
By way of example and not limitation, the sealing skirt 120 can be connected to the valve body 110 in a variety of ways, the sealing skirt 120 can be connected to the valve body 110 in a fixed manner, such as by bonding, ultrasonic welding, etc., or the sealing skirt 120 can be connected to the valve body 110 in a detachable manner, such as by screwing, snapping, magnetic attraction, etc.
Optionally, the sealing skirt 120 is integrally formed with the valve body 110, so as to enhance the connecting strength between the sealing skirt 120 and the valve body 110 and enhance the sealing performance at the connecting position between the sealing skirt 120 and the valve body 110.
In some embodiments, the sealing skirt 120 and the raised portion 121 are each made at least partially of a resilient material, which may be configured to both resiliently urge the raised portion 121 against the fluid reservoir 1000 and to allow the raised portion 121 to be forced apart by fluid pressure.
In some embodiments, the sealing skirt 120 and the protrusion 121 are all made of an elastic material to enhance the elastic abutting strength between the protrusion 121 and the fluid storage tank 1000, and thus the sealing strength of the protrusion 121.
In some embodiments, both the sealing skirt 120 and the protrusion 121 may also be made of an elastic material, for example, an end of the sealing skirt 120 close to the valve body 110 is made of an elastic material, an end of the sealing skirt 120 away from the valve body 110 is made of an elastic material, an end of the protrusion 121 close to the valve body 110 is made of an elastic material, an end of the protrusion 121 away from the valve body 110 is made of an elastic material, and the like. There are many types of the above-mentioned elastic materials, and the elastic materials may be rubber, plastic, silicone, etc., and are not particularly limited herein.
In some embodiments, when the protrusion 121 abuts against the fluid storage tank 1000, the sealing skirt 120 is spaced apart from the fluid storage tank 1000, so that only the protrusion 121 of the valve body 110 abuts against the fluid storage tank 1000, thereby reducing the contact area between the valve body 110 and the fluid storage tank 1000.
Through the technical scheme, when the fluid transfer valve 100 is used, the fluid inlet 110a of the valve body 110 is communicated with a fluid source, the protrusion part 121 is abutted against the fluid storage tank 1000 to form point-surface matching, the contact area of the sealing skirt 120 and the fluid storage tank 1000 is reduced, the fluid pressure required for flushing the sealing skirt 120 is reduced, and the sealing skirt 120 is conveniently flushed under the action of the fluid pressure. Also, the protrusion 121 can be flushed open by the fluid pressure to transfer the fluid to the fluid storage tank 1000, i.e., the fluid flowing out of the fluid outlet 110b can flow to the outside of the fluid transfer valve 100 to squeeze the fluid in the fluid storage tank 1000, so that the fluid in the fluid storage tank 1000 can flow to the outside of the fluid storage tank 1000. By providing the projection 121, the stability of the fluid in the output fluid storage tank 1000 can be improved.
Wherein the fluid storage tank 1000 may be used to store a fluid, which may include at least one of: gas, liquid. The fluid flowing out of the fluid outlet 110b and the fluid in the fluid storage tank 1000 (the fluid stored in the fluid storage tank 1000) may be different types of fluid, for example, the fluid flowing out of the fluid outlet 110b is gas, and the fluid stored in the fluid storage tank 1000 is liquid.
In some embodiments, the body 200 of the fluid storage tank 1000 has a reservoir chamber 200a and an opening 200b in communication with the reservoir chamber 200 a. The fluid outlet 110b of the valve body 110 extends into the storage cavity 200a through the opening 200b, so that the protrusion 121 abuts against the cavity wall of the storage cavity 200a to form a point-surface fit, and thus, the protrusion 121 can be flushed by fluid pressure, and further, fluid flowing out from the fluid outlet 110b is transmitted to the outside of the valve body 110, that is, the fluid flowing out from the fluid outlet 110b can be transmitted into the fluid storage tank 1000.
In some embodiments, the fluid flowing out of the fluid outlet 110b is gas, the fluid stored in the storage cavity 200a (the fluid stored in the fluid storage tank 1000) is liquid, the fluid storage tank 1000 further has an outlet (not shown) communicated with the storage cavity 200a, and the projection 121 is engaged with the point surface of the storage cavity 200a, so that the gas easily washes away the projection 121 and enters the storage cavity 200a, and the liquid in the storage cavity 200a can flow out of the outlet in order to balance the air pressure in the storage cavity 200a with the external air pressure.
In some embodiments, the fluid transfer valve 100 may further be configured to control the communication between the fluid storage tank 1000 and the external environment, the protrusion 121 is elastically abutted against the exterior of the fluid storage tank 1000, and the protrusion 121 is further disposed around the opening 200b, so that the protrusion 121 can be pushed open by the fluid pressure, so that the fluid storage tank 1000 is communicated with the external environment, and the fluid transferred by the fluid transfer valve 100 is a gas. At this time, the air in the external environment may flow into the fluid storage tank 1000 through the position where the protrusion 121 is pushed open, or the air in the fluid storage tank 1000 may flow into the external environment through the position where the protrusion 121 is pushed open, depending on the magnitude relationship between the air pressure in the fluid storage tank 1000 and the air pressure in the external environment.
Referring to fig. 1 to 4, it is understood that the number of the protrusions 121 may be one or at least two.
In some embodiments, the number of the protrusions 121 is at least two, at least two protrusions 121 each extend along the circumference of the sealing skirt 120, and the at least two protrusions 121 are spaced apart from each other. In this manner, the sealing strength between the valve body 110 and the fluid storage tank 1000 may be enhanced. Fig. 2 shows a case where the number of the protrusions 121 is two.
By way of example and not limitation, at least two protrusions 121 are spaced inwardly and outwardly.
In some embodiments, when each protrusion 121 can elastically abut against the fluid storage tank 1000, two adjacent protrusions 121 may be disposed at an interval, and two adjacent protrusions 121 may also be disposed in abutment with each other, that is, an inner wall of one protrusion 121 abuts against an outer wall of the other protrusion 121, which is not limited herein. Fig. 1 shows a case where two adjacent protrusions 121 are spaced apart from each other.
Referring to fig. 1 to 4, in some embodiments of the present invention, the width of the protrusion 121 gradually decreases from one end of the protrusion 121 close to the sealing skirt 120 to one end of the protrusion 121 far from the sealing skirt 120. With this arrangement, the width of the end of the protruding portion 121 away from the sealing skirt 120 can be effectively reduced, that is, the contact area between the protruding portion 121 and the fluid storage tank 1000 can be effectively reduced, and the sealing skirt 120 can be more conveniently pushed open under the action of fluid pressure.
By way of example and not limitation, the width of the boss 121 refers to the difference between the outer diameter of the boss 121 and the inner diameter of the boss 121.
In some embodiments, the end of the protrusion 121 away from the sealing skirt 120 is disposed in a sharp angle shape, so that the contact area between the protrusion 121 and the fluid storage tank 1000 can be greatly reduced, and the sealing skirt 120 can be easily broken by the action of the fluid pressure. When the number of the protrusions 121 is at least two, an end of at least one of the protrusions 121, which is away from the sealing skirt 120, is disposed in a sharp angle shape.
Referring to fig. 1 to 4, in some embodiments, the fluid delivery valve 100 is in communication with a fluid source through a pipe, and in order to determine whether the fluid delivery valve 100 is inserted into the pipe, a limiting protrusion 111 is disposed on an inner wall of the fluid channel 110c, and the limiting protrusion 111 is used for limiting the pipe inserted into the fluid channel 110 c. By such arrangement, when the fluid transfer valve 100 is communicated with a pipeline, the pipeline is inserted into the fluid channel 110c from the fluid inlet 110a until the pipeline abuts against the limiting protrusion 111, so that the fluid transfer valve 100 can be judged to be inserted in place with the pipeline, and otherwise, the fluid transfer valve 100 can be judged not to be inserted in place with the pipeline. Further, the valve body 110 can be restrained in the axial direction of the valve body 110 by the stopper projection 111 abutting against the pipe and the coupling projection 121 elastically abutting against the corresponding position of the fluid storage tank 1000, thereby enhancing the fixing strength of the valve body 110.
By way of example and not limitation, the limiting protrusion 111 is annularly arranged along the circumferential direction of the fluid channel 110c, and the arrangement is such that when the fluid transfer valve 100 is in plug-fit with a pipe, the acting force of the limiting protrusion 111 on the pipe can be uniformly distributed, so as to stabilize the plug-fit of the fluid transfer valve 100 with the pipe.
Referring to fig. 3 to 5, the present invention further provides a fluid storage tank 1000, wherein the fluid storage tank 1000 comprises a tank body 200 and the fluid transfer valve 100 as described above; the case 200 has a reservoir 200a and an opening 200b communicating with the reservoir 200a, the valve body 110 is located in the reservoir 200a, the fluid inlet 110a of the valve body 110 communicates with the opening 200b, and the protrusion 121 elastically abuts against a wall of the reservoir 200 a.
Specifically, the protrusion 121 elastically abuts against the inner wall of the storage cavity 200a facing the opening 200b, so as to facilitate the elastic abutment of the protrusion 121 against the cavity wall of the storage cavity 200 a.
The fluid stored in the storage chamber 200a may be gas and/or liquid, the number of the openings 200b may be one or more, and when the number of the openings 200b is plural, the fluid inlet 110a of the valve body 110 is communicated with at least one opening 200b, which is not particularly limited herein.
By the above technical solution, when fluid is transferred to the fluid storage tank 1000, the fluid is transferred into the fluid channel 110c after passing through the opening 200b and the fluid inlet 110a, and then transferred to the fluid outlet 110b through the fluid channel 110c, and then the protrusion 121 is pushed open by the fluid pressure, so that the fluid flows into the storage chamber 200 a. When the fluid is stopped being transferred to the fluid storage tank 1000, the protrusion 121 can elastically abut against the cavity wall at the corresponding position of the storage cavity 200a under the combined action of the self resilience and the resilience of the sealing skirt 120, so as to seal and close the fluid transfer valve 100.

And the fluid delivery pipe 300 is also abutted against the stopper projection 111 in the above-described embodiment.
