Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present utility model more apparent, the technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present utility model, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
The valve assembly provided by the embodiment of the utility model comprises a valve body 100, a valve core 200 and an elastic restoring member 300. Wherein, a fluid inlet 110 and a fluid outlet 120 are formed at both ends of the valve body 100, and a fluid channel 130 is formed between the fluid inlet 110 and the fluid outlet 120; the valve core 200 is arranged in the fluid channel 130; the elastic restoring member 300 is used for abutting against one side of the valve core 200 facing the fluid outlet 120, and the valve core 200 is suitable for forming a sealing connection position with the fluid inlet 110 under the action of elastic restoring force of the elastic restoring member 300; the valve body 100 is provided with a discharge hole 140 from the sealing connection position to a direction away from the fluid inlet 110, and the discharge hole 140 and the sealing connection position are arranged in a dislocation manner.
According to the valve assembly provided by the embodiment of the utility model, the valve body 100, the valve core 200 and the elastic reset piece 300 are arranged, and the valve core 200 and the valve body 100 are connected in a sealing way by utilizing the elastic restoring force of the elastic reset piece 300, so that when the pressure difference between the fluid inlet 110 side and the fluid outlet 120 side is smaller, or the pressure difference between the fluid outlet 120 side is larger, the valve assembly can keep good sealing performance; when the pressure on the fluid inlet 110 side is high, fluid can enter the fluid channel 130 to push the valve core 200 open, and flow out from the fluid outlet 120 and the discharge hole 140 formed on the valve body 100, so that the pressure on the fluid inlet 110 side and the fluid outlet 120 side can be balanced quickly and efficiently, and blockage is not easy to occur.
Specifically, the valve body 100 is formed in a hollow pipe structure. In this embodiment, the outer contour of the valve body 100 is configured to be cylindrical, so as to facilitate manufacturing. A fluid inlet 110 and a fluid outlet 120 are formed at both ends of the valve body 100. The fluid inlet 110 is disposed at a higher pressure end of the two ends of the valve body 100, and a fluid passage 130 is formed between the fluid inlet 110 and the fluid outlet 120. That is, during operation of the valve body 100, fluid enters the fluid passage 130 from the fluid inlet 110 at a relatively high pressure and exits from the fluid outlet 120.
The fluid channel 130 is configured to allow fluid to flow therein and to block the flow of fluid therein when the resilient return member 300 abuts the valve cartridge 200. For example, the cross-section of the fluid channel 130 may be circular to enable a rapid and uniform flow of fluid through the fluid channel 130. The fluid passage 130 may also be provided with structure adapted to mate with the valve cartridge 200 to achieve a good seal when the resilient return member 300 abuts the valve cartridge 200. It should be noted that, the diameter of the fluid channel 130 is larger than the diameter of the sealing connection position at a section of the sealing connection position between the valve core 200 and the valve body 100, which is close to the fluid outlet 120, so that the fluid can smoothly flow out after pushing the valve core 200 open.
The valve cartridge 200 is disposed within the fluid passage 130. In this embodiment, a chamfer is provided at a position where the valve core 200 and the valve body 100 cooperate to form a sealed connection at an end of the valve core 200 near the fluid inlet 110. This arrangement is advantageous for improving the sealing performance of the valve assembly when the resilient return member 300 abuts the valve cartridge 200. It should be noted that the foregoing is merely illustrative, and is not meant to limit the structure of the valve core 200, and those skilled in the art can reasonably design the structure of the valve core 200 according to practical situations.
The elastic restoring member 300 is used for abutting against the side of the valve core 200 facing the fluid outlet 120, and the valve core 200 is suitable for forming a sealing connection position with the fluid inlet 110 under the action of elastic restoring force of the elastic restoring member 300. As shown in fig. 1, the elastic restoring member 300 is provided inside the valve body 100 in a compressed state, and thus can apply an elastic restoring force to the side of the valve cartridge 200 toward the fluid outlet 120. The valve core 200 is pressed against the sealing connection position inside the valve body 100 by elastic restoring force, and forms a seal against the fluid at the fluid inlet 110.
By this arrangement, when the pressure difference between the fluid inlet 110 side and the fluid outlet 120 side is small or the pressure on the fluid outlet 120 side is large, the valve element 200 always abuts against the sealing connection position under the action of the elastic restoring force or the pressure, thereby ensuring the tightness of the device. When the pressure on the fluid inlet 110 side is large, the valve core 200 is displaced against the elastic restoring force by the pressure, and the fluid flows out of the fluid outlet 120 and the discharge hole 140 after entering the fluid passage 130, thereby balancing the pressure. It will be appreciated that the valve core 200 can be pushed only when the pressure on the fluid inlet 110 side is greater than the elastic restoring force of the elastic restoring member 300, and thus, the elastic restoring force of the elastic restoring member 300 needs to be set within a proper range, which can be set by those skilled in the art according to actual requirements.
The valve body 100 is provided with a discharge hole 140 from the sealing connection position to a direction away from the fluid inlet 110, and the discharge hole 140 and the sealing connection position are arranged in a dislocation manner. As shown in fig. 1, a discharge hole 140 for discharging fluid is formed in the valve body 100. To avoid affecting the tightness of the valve assembly, the vent 140 is positioned at a section of the valve body 100 away from the fluid inlet 110 from the sealing connection. Also, the location of the drain hole 140 does not include a sealing connection location.
By providing the vent 140, the passage of fluid out of the valve assembly is increased, increasing the rate at which the valve assembly balances the side pressure of the fluid inlet 110 side and the fluid outlet 120 side, and improving efficiency. In addition, the arrangement of a plurality of outflow channels improves fault tolerance, so that the possibility of balance function failure caused by channel blockage is reduced.
As shown in fig. 1, a plurality of the discharge holes 140 are spaced apart in the direction of the fluid passage 130. It is readily understood that the greater the number of vent holes 140, the greater the number of channels for venting fluid, and the faster the pressure equalization. A plurality of discharge holes 140 are provided at intervals in the direction of the fluid passage 130 in the present embodiment. The interval between the discharge holes 140 is not particularly limited in this embodiment, and those skilled in the art can reasonably arrange the embodiment according to practical situations.
According to an embodiment of the present utility model, a plurality of the exhaust holes 140 are arranged in a staggered manner on the sidewall of the valve body 100. That is, the discharge hole 140 may be formed in the direction of the fluid passage 130 or may be formed in the valve body 100 in a circumferentially offset manner, as long as the condition that the sealing connection is made in a direction away from the fluid inlet 110 is satisfied. This provides the possibility of providing more vent holes 140 in the valve body 100, thereby making the valve assembly more efficient and less prone to clogging.
As shown in fig. 1, the valve assembly according to the embodiment of the present utility model further includes a cover disposed at an end of the valve body 100 away from the fluid inlet 110. The cover body can prevent the fluid at the fluid outlet 120 from splashing, so that the safety of the device is improved, and the situation that equipment is damaged or even personal safety is endangered due to splashed fluid is avoided. It should be noted that the provision of the cover has no effect on the fluid discharge at the fluid outlet 120.
The cross-sectional area of the cover gradually decreases from the fluid inlet 110 toward the fluid outlet 120. For example, the cover may be formed as a conical surface or a hemispherical surface opening toward the fluid outlet 120. In other embodiments, the cover may be provided in other shapes that can play a role in preventing splashing, and is not limited herein, as long as the corresponding function can be achieved.
Further, the cover and the valve body 100 may be provided in an integrally formed form. The arrangement has the advantages of simplifying the process flow and saving the production cost.
According to the valve assembly provided by the embodiment of the utility model, the inner wall of the fluid channel 130 is formed with an abutting portion, and one end of the elastic restoring member 300 facing away from the valve core 200 is adapted to abut against the abutting portion. As shown in fig. 1, the abutment is formed as a boss on the inner wall of the fluid channel 130. The abutting portion can play a role in installing and fixing the elastic restoring member 300, in other words, one end of the elastic restoring member 300 abuts against the abutting portion, and the other end abuts against the valve core 200, so that an elastic restoring force can be applied to the valve core 200, and further, the sealing or pressure balancing function of the valve assembly can be achieved.
The elastic restoring member 300 may be a conventional spring. The advantage of setting like this is, can reduce the intensity of labour of design, is convenient for processing and purchase simultaneously, has improved efficiency. Of course, in other embodiments, the elastic restoring member 300 may have other structures capable of achieving elastic contraction and restoring.
The charging tank provided by the embodiment of the utility model comprises the valve assembly. The charging tank is used for containing materials. In production, the pressure tends to increase as the internal space of the feed tank becomes smaller. That is, when the weight of the feed tank reaches the upper limit and the feed tank is full of feed liquid, the pressure becomes large due to the smaller space in the tank. Therefore, it is necessary to install the valve assembly described above on the feed tank to balance the pressure inside and outside the feed tank. It should be noted that the fluid inlet 110 is directed towards the interior of the feed tank and the fluid outlet 120 is directed towards the exterior of the feed tank during installation.
In production, it is often necessary to open the feed tank to add material, so the feed tank is provided with a tank body and a tank cover. In this case, the valve assembly is preferably mounted to the lid of the charging tank so as not to interfere with the function of the tank to store material.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present utility model, and are not limiting; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present utility model.
