Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a side-push type cream valve. Background Art

[0002] Generally speaking, the inlet of the spray cream valve used for spraying animal cream or vegetable cream is in a normally closed state when there is no external pressure. If the valve needs to be opened, a large pressure needs to be applied to the side of the valve stem: after the pressure is withdrawn, the valve relies on the rebound force of the sealing plug to complete the closing action. This valve has high requirements for the rebound force of the sealing plug. Because it is made of rubber, it is easily affected by the ambient temperature and the use environment. Once the rebound force is abnormal, it will cause the valve to leak. Generally, a valve stem channel is set inside the valve stem, and a flow hole connected to the valve stem channel is set on the side of the valve stem near the bottom. The aperture determines the flow rate of the spray cream. Due to its own structural limitations, on the one hand, the flow rate is difficult to meet the demand; on the other hand, because cream is a fatty semi-solid food, it will adhere to the corresponding contact surface during its passage through the valve stem channel, making it difficult to clean.

[0003] In response to this, our company has developed a washable valve for food (patent number CN202220852153.9). After the valve is assembled with the tank body, it is necessary to inflate the tank. During the inflation process, the gas pressure will press the valve stem down to the mouth of the sealing plug, so that the valve enters the open state, and the air flow is injected into the tank from the flow groove on the side of the valve stem. This inflation method is slow and difficult to inflate. In order to ensure sufficient inflation during the inflation process, the inflation pressure will be increased, and excessive air pressure will easily push the valve stem and the sealing plug into the tank. Utility Model Content

[0004] In order to solve the technical problems existing in the background technology, the utility model proposes a side-push type cream valve.

[0005] The utility model provides a side-push type cream valve, comprising: a valve stem and a sealing plug sleeved on the valve stem, wherein:

[0006] A sealing seat and a plug are respectively provided at the two ends of the valve stem of the sealing plug, and the distance between the sealing seat and the plug is greater than the axial height of the sealing plug; an axially extending flow groove is provided on the side wall of the valve stem between the sealing seat and the plug, and the top end of the flow groove passes through the plug to form an open end.

[0007] Preferably, the flow groove is a V-shaped groove.

[0008] Preferably, a plurality of flow grooves are provided and evenly distributed axially, and the top end of at least one flow groove passes through the plug to form an open end.

[0009] Preferably, the sealing seat is located at the end of one end of the valve stem, and the plug is located between the two ends of the valve stem to separate the valve stem into a main stem portion located between the plug and the sealing seat and an end stem portion located at the end of the plug away from the sealing seat.

[0010] Preferably, the top of the end rod portion is a dome structure.

[0011] Preferably, an angle A smaller than 90° is formed between the lower end surface of the plug and the axial surface of the valve stem, and an angle B matching the angle A is formed between the upper end surface of the sealing plug and the wall of its inner hole.

[0012] In the utility model, the distance between the sealing seat and the plug is greater than the axial height of the sealing plug, so that the valve stem has an axial movable space in the sealing plug. In this way, on the one hand, the user can more easily open the valve when pushing the sealing plug sideways, and on the other hand, it is easier to clean the valve stem surface and the inside of the flow slot by pulling the valve stem up and down. The top of the flow slot passes through the plug to form an open end, which can prevent the plug from forming an obstruction above the flow slot and affecting the discharge speed when discharging. At the same time, when inflating the tank, the gas can directly enter the tank from the open end of the flow slot, thereby increasing the inflation volume and inflation speed, and also preventing the valve stem and the sealing plug from being rushed into the tank due to excessive air pressure. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 The utility model is a schematic structural diagram of a side-push type cream valve.

[0014] Figure 2 The utility model discloses a schematic structural diagram of a valve stem in a side-push type cream valve. DETAILED DESCRIPTION

[0015] Reference Figure 1-2 The utility model provides a side-push type cream valve, comprising: a valve stem 1 and a sealing plug 2 sleeved on the valve stem 1, wherein:

[0016] A sealing seat 3 and a plug 4 are respectively provided at the two ends of the valve stem 1 of the sealing plug 2, and the distance between the sealing seat 3 and the plug 4 is greater than the axial height of the sealing plug 2, so that the valve stem 1 has axial activity space in the sealing plug 2. In this way, on the one hand, the user can more easily open the valve when pushing the sealing plug 2 sideways, and on the other hand, it is easier to clean the surface of the valve stem 1 and the inside of the flow groove 5 by pulling the valve stem 1 up and down.

[0017] The valve stem 1 is provided with an axially extending flow slot 5 on the side wall between the sealing seat 3 and the plug 4, and the top of the flow slot 5 passes through the plug 4 to form an open end. When the tank needs to be inflated, the gas can directly enter the tank from the open end of the flow slot 5, thereby increasing the inflation volume and inflation speed, and also preventing the valve stem 1 and the sealing plug 2 from being rushed into the tank due to excessive air pressure; and the tank can also be directly sprayed out from the top of the flow slot, increasing the injection volume and injection speed.

[0018] When in use, the valve is first assembled with the material tank, and then air is inflated into the tank from the open end at the top of the flow slot 5. After the inflation is completed, the pressure in the tank pushes the sealing seat 3 of the valve stem 1, so that the sealing seat 3 of the valve stem 1 and the sealing plug 2 fit tightly, thereby closing the valve; when in use, the sealing plug 2 is driven to produce spatial displacement by applying lateral pressure to the sealing plug 2, thereby pushing the valve stem 1 to move downward relatively, and then a gap appears between the sealing seat 3 of the valve stem 1 and the sealing plug 2, that is, the valve is opened, and at this time the contents can enter the flow slot 5 of the valve stem 1 through the gap and flow out from the open end of the outflow slot 5.

[0019] In a further embodiment, the flow groove 5 is a V-shaped groove, so that the flow groove 5 can discharge materials more smoothly and be cleaned more conveniently.

[0020] Furthermore, a plurality of flow slots 5 are provided and evenly distributed axially, and the top end of at least one flow slot 5 passes through the plug 4 to form an open end.

[0021] In addition, in this embodiment, the sealing seat 3 is located at the end of one end of the valve stem 1, and the plug 4 is located between the two ends of the valve stem 1 to separate the valve stem 1 into a main rod portion 11 located between the plug 4 and the sealing seat 3 and an end rod portion 12 located at the end of the plug 4 away from the sealing seat 3. The end rod in the valve stem 1 is convenient for pulling up and down during the cleaning process.

[0022] Furthermore, the top of the end rod portion 12 is a dome structure.

[0023] Reference Figure 2 In addition, in order to achieve locking of the valve stem 1 and the sealing plug 2 in the downward pulling direction so that the valve stem 1 will not slip out of the sealing plug 2 when subjected to a downward thrust, the present embodiment sets the lower end face of the plug 4 to form an angle A less than 90° with the axial surface of the valve stem 1, and sets the upper end face of the sealing plug 2 to form an angle B matching the angle A with the inner hole wall thereof, so that the lower end face of the plug 4 and the upper end face of the sealing plug 2 form an inclined surface with the inner end facing upward and the outer end facing upward, so that the plug 4 cannot pass over the end of the sealing plug 2, thereby ensuring that the valve stem 1 will not slip out of the sealing plug 2 when subjected to a thrust of air pressure.

[0024] As can be seen from the above, the spacing between the sealing seat 3 and the plug 4 in the utility model is greater than the axial height of the sealing plug 2, so that the valve stem 1 has an axial movable space in the sealing plug 2. In this way, on the one hand, the user can more easily open the valve when pushing the sealing plug 2 sideways, and on the other hand, it is easier to clean the surface of the valve stem 1 and the inside of the flow slot 5 by pulling the valve stem 1 up and down. The end of the flow slot 5 close to the plug 4 penetrates the plug 4 to form an open end. When the tank is inflated, the gas can directly enter the tank from the open end of the flow slot 5, thereby increasing the inflation volume and inflation speed, and also preventing the valve stem 1 and the sealing plug 2 from being rushed into the tank due to excessive air pressure.

[0025] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
