Description

Technical Field

[0001] The invention belongs to the technical field of wine drinking equipment and relates to a wine dispensing faucet. Background Art

[0002] In order to draw out the wine in the barrel, a traditional wine barrel is usually equipped with a wine spear at the barrel mouth, and the wine tap generally includes a valve body and a connecting component connected to the valve body. The valve body is connected to the wine spear through the connecting component. When the wine flows out, high-pressure carbon dioxide gas enters the barrel, so that when the wine tap is opened, the wine in the barrel flows out through the wine spear and the wine tap in turn under the action of high pressure.

[0003] Traditional wine barrels are less convenient to use and have high costs because they need to be connected to carbon dioxide cylinders. For this reason, wine barrels that do not need to be connected to carbon dioxide cylinders and can allow wine to flow out automatically under the action of gravity and matching wine taps have appeared on the market. For example, a beer barrel wine valve disclosed in Chinese patent literature (authorization announcement number: CN2260931Y) includes a gas-liquid distribution valve body, a spiral boss and a wine valve core top column at its front end, and a gas channel and a liquid channel are respectively provided on both sides of the gas-liquid distribution valve body. The air inlet end of the gas channel is connected to the air inlet valve, and the gas channel passes through the wine valve core top column and is connected to the straw in the beer barrel. One end of the liquid channel is connected to the wine outlet, and the other end outlet is on the outside of the middle of the plane on the spiral boss, and is connected to the inner cavity of the beer barrel through the side hole of the wine spear body.

[0004] During use, the beer barrel dispensing valve has the following deficiencies: the dispensing valve is provided with an air inlet valve and a dispensing valve body on both sides of the gas-liquid distribution valve body, so that it has the dual functions of air intake and dispensing. However, the dispensing valve needs to be provided with seals in the air inlet valve and the dispensing valve body, so it is usually necessary to use more seals. At this time, since the sealing parts of each seal may have manufacturing defects, installation errors, wear and tear and other unavoidable situations, each sealing part is a potential source of leakage. Therefore, as the number of seals in the dispensing valve increases, the risk of leakage of the dispensing valve also increases, which leads to the problem of insufficient sealing reliability of the dispensing valve. Summary of the invention

[0005] The purpose of the present invention is to address the above-mentioned problems in the prior art and to propose a wine dispensing faucet, which solves the problem of insufficient sealing reliability of the existing wine dispensing faucet with dual functions of dispensing wine and inletting air.

[0006] The objectives of the present invention can be achieved through the following technical solutions: a wine faucet, comprising a valve body, a valve stem, a sealing member made of a rubber material and a pressure cap fixedly arranged in the valve body, the valve body having an air inlet channel and a wine outlet channel, characterized in that the upper end of the air inlet channel has an installation port 1, the upper end of the wine outlet channel has an installation port 2 flush with the installation port 1, the sealing member comprises a sheet-shaped sealing member and two cylindrical plugging members integrally formed with the sealing member, the pressure cap presses the sealing member downward so that the sealing member seals against the edge surfaces of the installation port 1 and the installation port 2, one of the plugging members of the sealing member extends from the installation port 1 into the air inlet channel and can block the air inlet channel, the other plugging member extends from the installation port 2 into the wine outlet channel and can block the wine outlet channel, the valve stem has two plunger members parallel to each other and the valve stem can move along the axial direction of the plunger member, and the two plugging members of the sealing member are fixedly sleeved on the two plunger members in a one-to-one correspondence.

[0007] The wine faucet is installed on a wine barrel for use. The wine faucet is provided with an air inlet channel having a first installation port and a wine outlet channel having a second installation port, so that the two plugging parts of the sealing member can extend into the air inlet channel and the wine outlet channel respectively, and the two plugging parts are pushed by the axial direction of the valve stem to move to block the air inlet channel and the wine outlet channel respectively, thereby closing the wine faucet. Conversely, the valve stem is reset and drives the two plugging parts to move in the opposite direction to open the air inlet channel and the wine outlet channel respectively. At this time, the external gas can enter the wine barrel through the air inlet channel, ensuring that the pressure in the wine barrel is balanced with the outside without negative pressure, and the wine in the wine barrel can flow out through the wine outlet channel under the action of gravity for people to drink.

[0008] In the present wine faucet, since the sealing member has a sheet-shaped sealing portion and two cylindrical plugging portions, and the mounting port 1 is flush with the mounting port 2, the sealing portion of the sealing member can simultaneously abut against the edge surfaces of the mounting port 1 and the mounting port 2, so that when the pressure cap presses the sealing portion downward, the sealing portion can form a seal with the edge surfaces of the mounting port 1 and the mounting port 2. In this way, the mounting port 1 and the mounting port 2 are blocked simultaneously by the sealing portion of the sealing member, so that the sealing portion can not only isolate the air inlet channel and the wine outlet channel, so that the air inlet channel and the wine outlet channel of the wine faucet are not connected to each other, but also the sealing portion realizes the isolation between the air inlet channel and the valve stem mounting cavity, and between the wine outlet channel and the valve stem mounting cavity, so that the medium in the air inlet channel and the wine outlet channel will not leak out.

[0009] The seal of the wine faucet has a unique shape design, and the matching valve stem has two parallel plunger parts, so that the two plugging parts of the seal can be fixedly mounted on the two plunger parts in a one-to-one correspondence, so that the valve stem can drive the two plugging parts of the seal to move axially to achieve the connection or blocking of the air inlet channel and the wine outlet channel. Therefore, the wine faucet can achieve multiple sealing requirements in the valve body through a seal (i.e., the connection or blocking of the air inlet channel and the wine outlet channel to achieve the opening and closing of the wine faucet; the isolation seal between the air inlet channel and the wine outlet channel so that the air inlet channel and the wine outlet channel are not connected to each other; the isolation seal between the air inlet channel, the wine outlet channel and the valve stem mounting cavity). This design enables the wine faucet to effectively reduce the number of seals while achieving the dual functions of air intake and wine outlet, avoiding the problem in the prior art that the sealing part of each seal is prone to form a potential leakage source due to the large number of seals, thereby greatly reducing the leakage risk of the wine faucet, ensuring that the wine faucet has good sealing reliability and a long service life. In addition, the design of the valve stem of the wine faucet can also drive the two plugging parts to move axially at the same time to synchronously open or block the air inlet channel and the wine outlet channel, thereby improving the sealing reliability. At the same time, since one-open dual control can be achieved, the wine faucet is more convenient to operate.

[0010] In the above-mentioned wine faucet, the valve body has a plate-shaped and vertically arranged partition, and the partition divides the inner cavity of the valve body so that the two sides of the partition respectively form the air inlet channel and the wine outlet channel. The air inlet channel and the wine outlet channel are separated by the partition, which is not only convenient for manufacturing and saves materials, but also the design allows the air inlet channel and the wine outlet channel to be arranged adjacent to each other, and then the installation port one and the installation port two can also be arranged adjacent to each other, so that it is convenient to block the installation port one and the installation port two at the same time through the sealing part of the seal, which is of great benefit to the optimized design of the seal, so that the seal can better realize the isolation seal between the air inlet channel and the wine outlet channel, as well as the isolation seal between the air inlet channel, the wine outlet channel and the valve stem installation cavity, so that the purpose of reducing the number of seals can be achieved, so that the leakage risk of the wine faucet is greatly reduced, and the sealing reliability of the wine faucet is improved.

[0011] In the above-mentioned wine faucet, the valve body also has a transversely arranged blocking portion, one section of the air inlet channel is an air guide hole opened on the blocking portion, and the plugging portion located in the air inlet channel can block the air guide hole, and one section of the wine outlet channel is a wine guide hole opened on the blocking portion, and the plugging portion located in the wine outlet channel blocks the wine guide hole. Since one section of the air inlet channel is an air guide hole, when the air guide hole is blocked, the air inlet channel is blocked. Similarly, when the wine guide hole is blocked, the wine outlet is blocked. The wine faucet is made of plastic material, and the transverse arrangement of the blocking portion can increase the structural strength of the valve body, making the valve body less prone to damage and improving the quality of the wine faucet. In addition, the blocking portion has good structural strength, so it can better withstand the pressure applied downward by the plugging portion. When the plugging portion abuts against the upper openings of the air guide hole and the wine guide hole, the blocking portion is not easy to deform, thereby improving the sealing effect and ensuring that the wine faucet has good sealing reliability.

[0012] In the above-mentioned wine faucet, the inner peripheral wall of the valve body is provided with an annular step arranged in the circumferential direction, the top edge of the partition is flush with the annular step, one half of the annular step is enclosed with the top edge of the partition to form installation opening 1, and the other half of the annular step is enclosed with the top edge of the partition to form installation opening 2. This structure makes installation opening 1 and installation opening 2 not only adjacent but also flush, so that installation opening 1 and installation opening 2 can be easily blocked at the same time by the sealing part of the seal, so that the seal can better achieve the isolation seal between the air inlet channel and the wine outlet channel, as well as the isolation seal between the air inlet channel, the wine outlet channel and the valve stem installation cavity, thereby improving the sealing reliability of the wine faucet.

[0013] In the above-mentioned wine faucet, the pressing cap includes a main body in the shape of a cylinder, and a pressing portion in the shape of a sheet which is perpendicular to the main body is integrally formed at the lower end of the main body, and the edge of the sealing portion of the sealing member is clamped between the main body and the annular step, and the portion of the sealing portion that abuts against the partition is clamped between the pressing portion and the top edge of the partition. By providing the pressing cap, the edge of the sealing portion is clamped between the lower end surface of the main body and the annular step, and the portion of the sealing portion that abuts against the partition is clamped between the pressing portion and the top edge of the partition. This can improve the sealing effect, ensure that the gas in the air inlet channel and the wine in the wine outlet channel will not leak into the valve stem mounting cavity, and at the same time better realize the isolation seal between the air inlet channel and the wine outlet channel, thereby improving the sealing reliability of the wine faucet.

[0014] In the above-mentioned wine faucet, the valve stem includes a rod-shaped driving portion and a sheet-shaped connecting portion located at the lower end of the driving portion, and two plunger portions are integrally formed on the lower side of the connecting portion. The plugging portion of the sealing member has a connecting hole with a closed lower end and an open upper end, and the lower end of the plunger portion is fixedly connected to the inner wall of the connecting hole of the corresponding plugging portion. The one-piece molding of the valve stem is not only convenient for manufacturing, but also ensures that the valve stem has good structural strength. The provision of the connecting hole can facilitate the connection between the plugging portion of the sealing member and the plunger portion of the valve stem, ensuring that the plunger portion can stably drive the plugging portion to move up and down, thereby improving the reliability of use and the sealing stability of the wine faucet.

[0015] In the above-mentioned wine faucet, the pressing part is provided with two clearance holes, and the two plunger parts of the valve stem respectively pass through the two clearance holes. By providing the clearance holes, the plunger part of the valve stem can pass through the pressure cap and connect with the plug part of the sealing member, making the wine faucet easy to assemble.

[0016] In the above-mentioned wine faucet, the upper end of the valve body has a mounting port and is threadedly connected with a gland, the gland is inserted into the valve body through the mounting port, the top of the gland has a top plate, the upper end surface of the main body of the gland abuts against the inner wall of the top plate, and the driving part of the valve stem is sleeved with a spring for pushing the valve stem downward. The spring presses the valve stem downward, so that when the faucet is closed, the valve stem always has a tendency to move downward, thereby ensuring that the two plugging parts of the seal stably abut against the upper openings of the air guide hole and the wine guide hole, ensuring that the wine faucet has good sealing reliability, so that it is not easy to leak when the faucet is closed.

[0017] In the above-mentioned wine tap, an extension part is also integrally formed on the outer wall of the valve body, and the extension part has an air guide channel and a wine guide channel parallel to each other, one end of the air guide channel is connected to the air inlet channel, and one end of the wine guide channel is connected to the wine outlet channel. When the wine tap is opened, the external gas can enter the wine barrel through the air inlet channel and the air guide channel in sequence, ensuring that the pressure in the wine barrel is balanced with the external environment without negative pressure, and the wine in the wine barrel flows out through the wine guide channel and the wine outlet channel in sequence for people to drink.

[0018] In the above-mentioned wine faucet, the driving part of the valve stem passes through the top plate and is connected to a handle for driving the valve stem to move axially. By pulling the handle, the valve stem can be driven to move axially up and down, making the wine faucet more convenient and labor-saving to use.

[0019] Compared with the prior art, the wine tap has the following advantages:

[0020] 1. While realizing the dual functions of air intake and wine dispensing, the wine faucet effectively reduces the number of seals, avoiding the problem in the prior art that a large number of seals cause the sealing parts of each seal to easily become a potential source of leakage, thereby greatly reducing the leakage risk of the wine faucet, ensuring that the wine faucet has good sealing reliability and a long service life.

[0021] 2. The valve stem of the wine faucet can simultaneously drive the two plugging parts to move axially to synchronously open or block the air inlet channel and the wine outlet channel, thereby realizing one-open dual control, thus making the wine faucet more convenient to operate.
