Technical Field

[0001] This utility model belongs to the field of food processing technology, specifically relating to a back pressure valve for a whipping machine. Background Technology

[0002] In the fluid transport and processing processes of industries such as food, chemicals, and pharmaceuticals, it is often necessary to precisely control the flow rate of materials and maintain a stable back pressure in the pipeline. For example, in the whipping and filling process of materials such as cream and sauces, it is necessary to control the discharge speed and maintain the pressure inside the whipping chamber to ensure product quality.

[0003] Currently, common back pressure valves suffer from inconvenient pressure setting adjustment and difficulty in achieving precise and continuous flow regulation. Therefore, there is a need to provide a back pressure valve for a blower to solve the above-mentioned technical problems. Utility Model Content

A diaphragm is fixedly connected to the valve body. A valve tube is provided on one side of the diaphragm. One end of the valve tube is fixedly connected to the valve body and communicates with the feed inlet. The other end of the valve tube is provided with a valve core assembly fixedly connected to the diaphragm, which is used to regulate the material flow rate in the valve tube.

[0006] Preferably, the edge of the diaphragm is clamped and fixedly connected between the valve body and the valve cover, for dividing the cavity formed by the valve body and the valve cover into a material-side chamber and a pneumatic-side chamber that are airtightly isolated from each other.

[0007] Preferably, the valve core assembly includes a valve seat and a valve core body, which are clamped and fixed on both sides of the diaphragm. The valve seat is disposed inside the pneumatic side chamber, and the valve core body is disposed inside the material side chamber and is adapted to the valve port on the valve tube.

[0008] Preferably, the valve core body has a conical structure.

[0009] Preferably, the diaphragm has a composite laminate structure, comprising at least one barrier layer and a support layer, wherein the barrier layer and the support layer are fixedly connected.

[0011] Preferably, the support layer is located on the side facing the pneumatic side chamber, and the support layer is made of fluororubber, nitrile rubber or EPDM rubber.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention adjusts the pressure setting value of the air inlet to drive the diaphragm to deform, thereby causing the valve core assembly to move relative to the valve tube, thus continuously adjusting the opening of the valve tube and controlling the flow rate of the material. This achieves the purpose of precise material flow and continuous material adjustment. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example Please see Figure 1-4 This embodiment provides the following technical solution: a back pressure valve for a blower, including a valve body 1, a feed inlet 2 at the left end of the valve body 1, a discharge outlet 3 on the side wall of the valve body 1, a valve cover 4 fixedly connected to the right end of the valve body 1, and the edge of the valve cover 4 is fixedly connected to the edge of the valve body 1 by bolts, and an air inlet 5 is provided on the valve cover 4, through which compressed air can be connected for control.

[0016] A diaphragm 6 is fixedly connected inside the valve body 1. A valve tube 7 is provided on the left side of the diaphragm 6. The left end of the valve tube 7 is fixedly connected to the valve body 1 and communicates with the feed inlet 2. A valve core assembly is provided on the right end of the valve tube 7 and is fixedly connected to the diaphragm 6. It is used to regulate the material flow rate in the valve tube 7. By adjusting the pressure set value of the air inlet 5, the diaphragm 6 is driven to deform, thereby driving the valve core assembly to move relative to the valve tube 7, thereby continuously adjusting the opening of the valve tube 7, thus controlling the material flow rate and achieving the purpose of precise material flow rate and continuous material regulation.

[0017] The edge of the diaphragm 6 is clamped and fixed between the valve body 1 and the valve cover 4, and is used to divide the cavity formed by the valve body 1 and the valve cover 4 into a material side chamber and a pneumatic side chamber that are airtightly isolated from each other. The edge of the diaphragm 6 is provided with bolt holes, so that when the valve body 1 and the valve cover 4 are fixed by bolts, the diaphragm 6 can be clamped and fixed between the valve body 1 and the valve cover 4.

[0018] The valve core assembly includes a valve seat 8 and a valve core body 9. The valve seat 8 and the valve core body 9 are clamped and fixed on both sides of the diaphragm 6. The valve seat 8 is located inside the pneumatic side chamber, and the valve core body 9 is located inside the material side chamber and is adapted to the valve port on the valve tube 7. The valve tube 7 is opened and closed and the flow rate is regulated by the cooperation between the conical surface of the valve core body 9 and the valve port of the valve tube 7.

[0019] In some embodiments, the valve core body 9 has a conical structure, which enables the valve core body 9 to cooperate with the valve tube 7 to adjust the opening and closing degree of the valve port on the valve tube 7.

[0020] The diaphragm 6 has a composite laminate structure, including at least one barrier layer and a support layer. The barrier layer and the support layer are fixedly connected. The barrier layer is located on the side facing the material-side chamber and is made of polytetrafluoroethylene (PTFE). This allows the barrier layer to directly face the material, providing optimal chemical resistance and non-stick properties. The support layer is located on the side facing the pneumatic side chamber and is made of fluororubber, nitrile rubber, or EPDM rubber. This gives the support layer good elasticity, ensuring that the diaphragm 6 can be repeatedly and flexibly bent and deformed without fatigue damage. The working principle of this utility model is as follows: In use, the pressure valve on the external compressed air supply device is used to adjust the intake air volume of the compressed air into the inlet 5. As the intake air volume gradually increases, the diaphragm 6 is driven to deform, thereby driving the valve core body 9 to move towards the valve tube 7. At this time, the opening of the discharge end on the valve tube 7 gradually decreases, thereby gradually reducing the amount of material at the discharge port 3. As the intake air volume gradually decreases, the diaphragm 6 can gradually return to its original position under the action of elasticity. The diaphragm 6 drives the valve core body 9 to move away from the valve tube 7, and the opening of the discharge end on the valve tube 7 gradually increases, thereby gradually increasing the amount of material at the discharge port 3.

[0021] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
