Description

Technical Field

[0001] The utility model relates to the technical field of valve cores of liquid-filling guns, in particular to an enhanced valve core of a liquid-filling gun. Background Art

[0002] With the development of society, the valve core of a liquid filling gun plays a vital role in various liquid filling operations. As one of the core components of the liquid filling gun, the valve core directly affects the performance of the liquid filling gun and the accuracy of the liquid filling. Its main function is to control the flow of liquid in the liquid filling gun. Through precise opening and closing actions, it ensures that the liquid can be filled according to the predetermined flow rate and pressure. Liquid filling guns are widely used in many fields such as industrial production, chemical transportation, and automobile refueling.

[0003] However, existing filling gun valve cores present numerous problems over extended use. The continuous impact of liquid can easily damage the valve core, which can degrade its sealing performance and cause liquid leakage during the filling process. This not only wastes liquid but can also pollute the surrounding environment. Furthermore, valve core damage can affect the precision of liquid flow control, leading to inaccurate filling quantities. This can severely impact product quality or even cause economic losses in industrial or commercial applications where strict filling volume requirements are crucial. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and provides an enhanced valve core for a liquid adding gun.

[0005] In order to achieve the above-mentioned object, the present invention adopts the following technical solutions: an enhanced liquid filling gun valve core, comprising a liquid filling gun body, a valve core housing fixedly mounted inside the liquid filling gun body, a buffer assembly mounted inside the rear end of the valve core housing, and a control assembly mounted inside the front end of the valve core housing;

[0006] The buffer assembly includes a disc, a conical block, a connecting ring, a first circular hole and a second circular hole. The disc is fixedly connected to the rear end of the inner wall of the valve core housing, the conical block is movably installed at the rear end of the disc, and the connecting ring is fixedly connected to the rear end of the conical block. The first circular hole has multiple annular openings inside the connecting ring, and the second circular hole has multiple annular openings inside the disc.

[0007] Further: the buffer assembly also includes a support rod, a stopper and a spring. The support rod is fixedly connected to the front end of the conical block and passes through the disc. The stopper is fixedly connected to the front end of the support rod and is located at the front end of the disc. The spring is fixedly connected between the conical block and the disc and is sleeved on the outer wall of the support rod.

[0008] Further: the buffer assembly also includes a support ring, a first slider and a first slide groove. The support ring is fixedly connected to the front end of the connecting ring. The first slider has multiple annular portions fixedly connected to the outer wall of the support ring. The first slide groove has multiple annular portions opened on the inner wall of the valve core housing. The first slider is located inside the first slide groove.

[0009] Further: the control component includes a blade, a mounting shaft, a mounting groove, a clamping block and a conical slope. The blade has multiple annular movably installed at the front end of the valve core housing, and the multiple blades form a closed cone when combined. The mounting shaft has multiple annular fixed connections to the front end of the valve core housing. The mounting groove is opened at the rear end of the blade, and the mounting shaft is located inside the mounting groove. The clamping block is threadedly installed at the front end of the outer wall of the valve core housing. The conical slope is opened on the inner wall of the clamping block, and the conical slope is in contact with the outer wall of the blade.

[0010] Furthermore: the outer wall of the clamping block is provided with anti-slip grooves, and the anti-slip grooves are distributed in a ring shape. The outer wall of the liquid adding gun body is provided with grooves, and the grooves are located corresponding to the outer wall of the clamping block.

[0011] Further: a sealing ring is slidably installed inside the gun body of the liquid adding gun, a second slider is fixedly connected to the outer wall of the sealing ring, a second sliding groove is provided on the inner wall of the gun body of the liquid adding gun, an annular retaining ring is fixedly connected to the rear end of the sealing ring, an annular retaining groove is provided at the front end of the clamping block, and the annular retaining ring is located inside the annular retaining groove.

[0012] The utility model has the following beneficial effects:

[0013] 1. Compared with the prior art, by providing a liquid-filling gun body, a valve core housing, a buffer assembly, a disc, a conical block, a connecting ring, a first circular hole, a second circular hole, a support rod, and a spring, when the liquid-filling gun starts working, the liquid first enters the interior of the liquid-filling gun body and directly impacts the conical block of the buffer assembly. Due to the conical design of the conical block, the impact force of the liquid is dispersed over a larger area, avoiding damage to the valve core caused by excessive local pressure. At the same time, the conical block will move forward under the action of the impact force, and the support rod fixedly connected to the front end of the conical block will move forward with the conical block, and the spring will also be compressed. The compression of the spring can absorb and store the energy generated by the liquid impact. When the impact force decreases, the spring will rely on its own elastic recovery force to push the conical block back to its original position. The liquid after the impact enters the valve core housing through the multiple first circular holes on the connecting ring and the multiple second circular holes on the disc. The utility model can effectively protect the valve core from damage caused by the impact force of the liquid, extend the service life of the valve core, and reduce various problems caused by valve core damage.

[0014] 2. Compared with the prior art, by setting the valve core housing, control assembly, blades, clamping block and conical slope, in the initial state of the control assembly, the clamping block is threadedly installed on the front end of the outer wall of the valve core housing, and the conical slope of its inner wall fits with the outer wall of the blade. Due to the effect of the conical slope, multiple blades merge into a closed cone under the pressure of the clamping block, realizing the interception function. When the liquid needs to flow out, the clamping block is rotated, and the clamping block is moved forward through the cooperation of the thread. At the same time, the conical slope is separated from the blade. At this time, the increase in liquid flow impacts the blades, flushes the blades, and allows the liquid to pass through the blades and discharge. The position of the clamping block can be controlled by rotating the clamping block, and the size of the blade opening can be controlled to control the size of the flow. The utility model can realize the precise control of liquid flow, improve the accuracy of filling, and meet the flow requirements of different filling scenarios. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Reference Figure 1-6The utility model provides an enhanced liquid-filling gun valve core: it includes a liquid-filling gun body 1, a valve core shell 2 is fixedly installed inside the liquid-filling gun body 1, a buffer component 3 is installed at the rear end of the valve core shell 2, and a control component 4 is installed at the front end of the valve core shell 2; the buffer component 3 includes a disc 301, a conical block 302, a connecting ring 303, a first circular hole 304 and a second circular hole 305, the disc 301 is fixedly connected to the rear end of the inner wall of the valve core shell 2, the conical block 302 is movably installed at the rear end of the disc 301, the connecting ring 303 is fixedly connected to the rear end of the conical block 302, the first circular hole 304 has a plurality of annular openings inside the connecting ring 303, and the second circular hole 305 has a plurality of annular openings inside the disc 301.

[0024] During use, after the liquid enters the liquid filling gun body 1, it directly hits the conical block 302. The special conical design of the conical block 302 can effectively disperse the impact force of the liquid, so that it can withstand the impact over a larger area, avoiding excessive local pressure. After the impact, the liquid enters the valve core housing 2 through the multiple first circular holes 304 on the connecting ring 303 and the multiple second circular holes 305 on the disc 301, avoiding the liquid from causing excessive pressure on the internal structure of the valve core due to concentrated impact, and the liquid in the valve core housing 2 is discharged through the control component 4.

[0025] The buffer assembly 3 also includes a support rod 306, a stop block 307 and a spring 308. The support rod 306 is fixedly connected to the front end of the conical block 302 and passes through the disc 301. The stop block 307 is fixedly connected to the front end of the support rod 306 and is located at the front end of the disc 301. The spring 308 is fixedly connected between the conical block 302 and the disc 301 and is sleeved on the outer wall of the support rod 306.

[0026] When the liquid impacts the conical block 302, the conical block 302 will move forward under the action of the impact force. At this time, the support rod 306 fixedly connected to the front end of the conical block 302 will move forward with the conical block 302. At the same time, the spring 308 will be compressed. The compression of the spring 308 can absorb and store the energy generated by the liquid impact. When the impact force decreases, the spring 308 will rely on its own elastic recovery force to push the conical block 302 back to its original position.

[0027] The buffer assembly 3 also includes a support ring 309, a first slider 310 and a first slide groove 311. The support ring 309 is fixedly connected to the front end of the connecting ring 303. The first slider 310 has multiple annular portions fixedly connected to the outer wall of the support ring 309. The first slide groove 311 has multiple annular portions opened on the inner wall of the valve core housing 2. The first slider 310 is located inside the first slide groove 311.

[0028] When the liquid impacts the conical block 302, the connecting ring 303 and the supporting ring 309 will produce a certain displacement under the action of the impact force. At this time, the first slider 310 will slide in the first slide groove 311, so that they can move along the predetermined direction when subjected to impact force, ensuring the stability of the overall structure of the buffer assembly 3.

[0029] The control component 4 includes a blade 401, a mounting shaft 402, a mounting groove 403, a clamping block 404 and a conical slope 405. The blade 401 has multiple annular movably installed at the front end of the valve core housing 2. When multiple blades 401 are combined, they form a closed cone. The mounting shaft 402 has multiple annular fixed connections to the front end of the valve core housing 2. The mounting groove 403 is opened at the rear end of the blade 401, and the mounting shaft 402 is located inside the mounting groove 403. The clamping block 404 is threadedly installed at the front end of the outer wall of the valve core housing 2. The conical slope 405 is opened on the inner wall of the clamping block 404, and the conical slope 405 is in contact with the outer wall of the blade 401.

[0030] In the initial state, the clamping block 404 is threadedly installed on the front end of the outer wall of the valve core housing 2, and the conical inclined surface 405 of its inner wall fits with the outer wall of the blade 401. Due to the action of the conical inclined surface 405, multiple blades 401 are combined into a closed cone under the pressure of the clamping block 404. At this time, the liquid cannot pass through, realizing the interception function; when the liquid enters the valve core housing 2 from the buffer assembly 3, the clamping block 404 is rotated, and the clamping block 404 is moved forward through the cooperation of the thread. At the same time, the conical inclined surface 405 is separated from the blade 401. At this time, the increase in liquid flow impacts the blade 401, and the blade 401 is flushed open, allowing the liquid to pass through the blade 401 and discharge; and the clamping block 404 can be rotated to control the position of the clamping block 404, so as to control the size of the opening of the blade 401 and thus control the size of the flow; when in use, the thread between the clamping block 404 and the valve core housing 2 can play a self-locking function to prevent liquid from flowing out.

[0031] The outer wall of the clamping block 404 is provided with anti-skid grooves 406 , and a plurality of anti-skid grooves 406 are distributed in a ring shape. The outer wall of the liquid filling gun body 1 is provided with slots 101 , and the slots 101 are located corresponding to the outer wall of the clamping block 404 .

[0032] During use, the operator can contact the anti-slip groove 406 through the groove 101 and use the anti-slip groove 406 to increase the friction between the finger and the clamping block 404, thereby conveniently moving the clamping block 404 for rotation.

[0033] A sealing ring 5 is slidably installed inside the liquid filling gun body 1, and a second slider 6 is fixedly connected to the outer wall of the sealing ring 5. A second slide groove 102 is provided on the inner wall of the liquid filling gun body 1, and an annular retaining ring 7 is fixedly connected to the rear end of the sealing ring 5. An annular retaining ring 7 is provided at the front end of the clamping block 404, and the annular retaining ring 7 is located inside the annular retaining groove 8.

[0034] During use, when the sealing ring 5 moves with the movement of the clamping block 404, the second slider 6 slides in the second slide groove 102, ensuring the stability of the movement of the sealing ring 5, so that the sealing ring 5 can fit tightly to the front end of the clamping block 404, preventing liquid from being discharged from the groove 101.

[0035] Working principle: When the liquid filling gun starts working, the liquid first enters the interior of the liquid filling gun body 1, and the liquid directly hits the tapered block 302 of the buffer assembly 3. Due to the conical design of the tapered block 302, the impact force of the liquid is dispersed over a larger area, avoiding damage to the valve core caused by excessive local pressure. At the same time, the tapered block 302 will move forward under the action of the impact force, and the support rod 306 fixedly connected to the front end of the tapered block 302 will move forward with the tapered block 302, and the spring 308 will also be compressed. The compression of the spring 308 can absorb and store the energy generated by the liquid impact. When the impact force decreases, the spring 308 will rely on its own elastic restoring force to push the tapered block 302 back to its original position. The impacted liquid enters the valve core housing 2 through the multiple first circular holes 304 on the connecting ring 303 and the multiple second circular holes 305 on the disc 301.

[0036] In the initial state of the control component 4, the clamping block 404 is threadedly installed on the front end of the outer wall of the valve core housing 2, and the conical slope 405 of its inner wall fits with the outer wall of the blade 401. Due to the action of the conical slope 405, multiple blades 401 are combined into a closed cone under the pressure of the clamping block 404, realizing the stopping function.

[0037] When the liquid needs to flow out, the clamping block 404 is rotated, and the clamping block 404 is moved forward through the cooperation of the thread. At the same time, the conical slope 405 is separated from the blade 401. At this time, the increase in liquid flow impacts the blade 401, and the blade 401 is pushed open, allowing the liquid to pass through the blade 401 and discharge; and by rotating the clamping block 404, the position of the clamping block 404 can be controlled, and the size of the opening of the blade 401 can be controlled to control the size of the flow.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
