Description

Technical Field

[0001] This utility model relates to the field of homogenizer equipment technology, and in particular to a direct one-way valve for homogenizers. Background Technology

[0002] Homogenizers are typically used under high production pressure conditions, so the check valves inside homogenizers generally adopt a cone valve structure to prevent internal leakage between the valve seat and the pump body during high-pressure production. Homogenizers can also be used in some low-pressure production conditions, or when used as a transfer pump. Because the production pressure of the homogenizer is relatively low, internal leakage is usually not a problem.

[0003] However, to meet the high-pressure production conditions of homogenizers, their internal structures all employ cone valves. This necessitates a corresponding conical design for the pump body's internal bore, resulting in high processing requirements, difficulty, and cost, thus increasing the overall cost of the homogenizer. Using a cone valve structure suitable for high-pressure production in low-pressure production does not meet cost management requirements. Therefore, there is a need for a direct-acting check valve for homogenizers that can solve the problem of increased production costs associated with using existing high-cost homogenizers with cone valve structures in low-pressure production. Summary of the Invention

[0004] The purpose of this invention is to provide a direct one-way valve for homogenizers, which can solve the problem of increased production costs caused by using high-cost homogenizers with cone valve structures in low-pressure production.

[0005] This utility model is implemented as follows:

[0006] A straight one-way valve for a homogenizer includes a straight valve core, a straight one-way valve seat, a combined sealing element, and a straight inner bore pump body. A straight cylindrical mounting hole is formed within the straight one-way valve seat, allowing the straight valve core, with its straight cylindrical structure, to be fitted into the straight cylindrical mounting hole of the straight one-way valve seat. A straight inner bore is formed within the straight inner bore pump body, and the outer surface of the straight one-way valve seat has a straight cylindrical structure, allowing the straight one-way valve seat to be fitted into the straight inner bore of the straight inner bore pump body. The combined sealing element is disposed on the straight one-way valve seat and seals against the bore wall of the straight inner bore.

[0007] The outer wall of the straight one-way valve seat has an indented mounting step, and the combined seal is embedded in the mounting step, so that the combined seal is sealed and fitted between the mounting step of the straight one-way valve seat and the wall of the inner hole of the straight cylinder.

[0008] The mounting step is in the form of a ring and is arranged circumferentially on the top and bottom of the outer wall of the one-way valve seat. The combined seal is also in the form of a ring and is embedded in the mounting step.

[0009] The combined sealing element includes an outer sealing element and an inner sealing element; the cross-section of the outer sealing element is a C-shaped structure with one side open, the open side of the outer sealing element is sealed and fitted on the mounting step, and the other side of the outer sealing element is sealed and fitted on the wall of the straight inner hole; the inner sealing element is embedded in the opening of the outer sealing element and pressed between the mounting step and the inner sealing element.

[0010] Compared with the prior art, this utility model has the following advantages:

[0011] 1. This utility model features a straight valve core, a straight one-way valve seat, and a straight inner bore pump body. The straight inner bores of the straight valve core, straight one-way valve seat, and straight inner bore pump body all adopt a straight cylindrical structure without a conical surface. Compared with the traditional cone valve structure, this greatly reduces the processing difficulty and cost. It can ensure sealing and leak-proof performance and reduce production costs when the homogenizer is used in low-pressure production or conveying conditions, meeting the requirements of cost management. Furthermore, the assembly between the straight valve core, straight one-way valve seat, and straight inner bore pump body is simpler and more convenient.

[0012] 2. This utility model features a combined sealing element, which is installed on the straight one-way valve seat via an installation step. This ensures reliable and convenient installation. Furthermore, the combined nested structure of the outer and inner sealing elements guarantees a tight fit between the combined sealing element and the straight inner wall of the straight inner bore pump body, forming a double sealing effect. This ensures the sealing and leak-proof performance of the straight one-way valve, meeting the low-pressure production requirements of the homogenizer and enabling the homogenizer to be applied at low cost in low-pressure production or transfer pump conditions.

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] Please see the appendix Figure 1 To be continued Figure 3A straight one-way valve for a homogenizer includes a straight valve core 1, a straight one-way valve seat 2, a combined sealing element 3, and a straight inner bore pump body 4. A straight cylindrical mounting hole 20 is formed inside the straight one-way valve seat 2, allowing the straight valve core 1, with its straight cylindrical structure, to be fitted into the straight cylindrical mounting hole 20. A straight inner bore 41 is formed inside the straight inner bore pump body 4. The outer surface of the straight one-way valve seat 2 has a straight cylindrical structure, allowing the straight one-way valve seat 2 to be fitted into the straight inner bore 41 of the straight inner bore pump body 4. The combined sealing element 3 is disposed on the straight one-way valve seat 2 and tightly seals against the bore wall of the straight inner bore 41.

[0019] The straight valve core 1 is a straight cylindrical valve core, and the straight one-way valve seat 2 is entirely a straight cylindrical structure without a conical surface. The straight inner bore 41 of the straight inner bore pump body 4 is also a straight cylindrical structure without a conical surface. Compared with the traditional cone valve structure, the processing requirements and difficulty are lower, and the cost is also lower. When the homogenizer equipped with the straight one-way valve of this utility model is used in low-pressure production conditions or as a transfer pump, production costs can be greatly reduced, thus meeting cost management requirements.

[0020] Please see the appendix Figure 2 and attached Figure 3 The outer wall of the straight one-way valve seat 2 has an inwardly recessed mounting step 21. The combined seal 3 is embedded in the mounting step 21, so that the combined seal 3 is tightly sealed and fitted between the mounting step 21 of the straight one-way valve seat 2 and the hole wall of the straight inner hole 41.

[0021] With the installation step 21, the installation of the combined seal 3 on the straight one-way valve seat 2 is simple and convenient. It can ensure that the combined seal 3 plays an effective sealing role while preventing the combined seal 3 from falling off, and can meet the usage requirements of the homogenizer under low-pressure production conditions.

[0022] The recessed depth of the mounting step 21 can be determined according to the thickness of the combined seal 3 to ensure that the combined seal 3 can fit tightly between the straight one-way valve seat 2 and the straight inner hole 41 after installation, so as to play a role in sealing and preventing leakage, and to meet the low-pressure production requirements of the homogenizer.

[0023] The mounting step 21 has a ring-shaped structure and is arranged circumferentially on the top and bottom of the outer wall of the one-way valve seat 2. The combined sealing element 3 also has a corresponding ring-shaped structure and is embedded in the mounting step 21.

[0024] The design of the annular mounting step 21 and the combined seal 3 can improve the sealing effect between the one-way valve seat 2 and the straight inner bore pump body 4.

[0025] Preferably, mounting steps 21 can be provided at both the top and bottom edges of the one-way valve seat 2, thereby further ensuring the sealing effect between the one-way valve seat 2 and the straight inner bore pump body 4 through two combined sealing elements 3.

[0026] Please see the appendix Figure 2 The combined sealing element 3 includes an outer sealing element 31 and an inner sealing element 32. The outer sealing element 31 has a C-shaped cross-section with one side open. The open side of the outer sealing element 31 is sealed and fitted onto the mounting step 21, and the other side of the outer sealing element 31 is sealed and fitted onto the wall of the straight inner hole 41. The inner sealing element 32 is embedded in the opening of the outer sealing element 31 and pressed between the mounting step 21 and the inner sealing element 32.

[0027] The combination design of the outer seal 31 and the inner seal 32 achieves a double pressing and sealing effect, further improving the sealing reliability between the one-way valve seat 2 and the straight inner hole pump body 4, thereby meeting the sealing and leak-proof requirements of the homogenizer under low-pressure production conditions.

[0028] Preferably, the outer seal 31 and the inner seal 32 can be conventional seals such as rubber sealing rings, and the extrusion deformation of the outer seal 31 and the inner seal 32 can achieve an effective double sealing effect.

[0029] Please see the appendix Figure 1 To be continued Figure 3 The assembly method of this utility model is as follows:

[0030] The straight valve core 1 with a straight cylindrical structure is matched and installed in the straight cylindrical mounting hole 20 of the straight one-way valve seat 2. Two combined seals 3 are respectively installed on the two mounting steps 21 of the straight one-way valve seat 2, and are installed together with the straight one-way valve seat 2 into the straight cylindrical inner hole 41 of the straight inner hole pump body 4. The outer surface of the outer seal 31 of the combined seal 3 is tightly sealed and fitted with the hole wall of the straight cylindrical inner hole 41, and the inner surface of the outer seal 31 is tightly sealed and fitted with the mounting step 21. The inner seal 32, which is embedded in the opening of the outer seal 31, is tightly sealed and fitted between the mounting step 21 and the inner wall of the opening of the outer seal 31, thereby effectively preventing material leakage.

[0031] Using a homogenizer equipped with the direct check valve of this invention in low-pressure production or conveying applications can better meet production requirements while also aligning with cost management considerations for homogenizers. The direct check valve of the homogenizer operates in the same way as a traditional cone valve, differing only in shape and structure; its working process will not be elaborated upon here.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the scope of protection of the present utility model.
