Description

Technical Field

[0001] The utility model relates to the technical field of homogenizer accessories, in particular to an inlaid high-pressure valve core. Background Art

[0002] The high pressure valve core of the homogenizer is required to have high wear resistance and corrosion resistance and meet the sanitary grade. Therefore, the high pressure valve core 1 of the homogenizer in the prior art adopts an integral structure. Figure 1 As shown, it is made by processing a whole piece of high hardness material such as ceramic.

[0003] However, the high-pressure valve core made of a whole piece of high-hardness material has the following disadvantages: ① The high-hardness material is brittle, and the sizes of different parts of the high-pressure valve core are different, which makes the processing of the high-pressure valve core difficult; ② The material is expensive and the processing cost is high, which is not conducive to popularization. Therefore, it is necessary to provide an inlaid high-pressure valve core that can solve the problem of high processing difficulty and high cost of high-pressure valve cores made of a whole piece of high-hardness material in the prior art. Summary of the invention

[0004] The utility model aims to provide an inlaid high-pressure valve core, which can solve the problems of high difficulty and high cost in processing the high-pressure valve core made of a whole piece of high-hardness material in the prior art.

[0005] The utility model is achieved in this way:

[0006] A mosaic high-pressure valve core comprises a homogenizing valve core body and a homogenizing head; an embedding groove is formed at the end of the homogenizing valve core body, so that one end of the homogenizing head is embedded in the embedding groove and the other end of the homogenizing head extends to the outside of the embedding groove to form the mosaic high-pressure valve core.

[0007] The inner diameter of the inlay groove is smaller than the outer diameter of the homogenizing head, so that one end of the homogenizing head is interference-fitted in the inlay groove.

[0008] The embedding direction of one end of the homogenizing head in the embedding groove is consistent with the material impact direction, and the other end of the homogenizing head is formed with a material impact surface, and the material impacts on the material impact surface.

[0009] The shape and size of the inlaid high-pressure valve core are consistent with those of the high-pressure valve core.

[0010] The hardness of the homogenizing head is greater than the hardness of the homogenizing valve core body.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The utility model is provided with a homogenizing valve core body and a homogenizing head. The homogenizing head is assembled into the inlay groove of the homogenizing valve core body by interference fitting and temperature difference assembly. The formed inlaid high-pressure valve core has the same shape, size and function as the integral high-pressure valve core in the prior art. The inlaid high-pressure valve core has high integrity and structural stability, does not affect the use of the high-pressure valve core, and the homogenizing head will not fall out of the homogenizing valve core body under the impact of the material.

[0013] 2. The utility model is provided with a homogenizing valve core body and a homogenizing head. The homogenizing valve core body can be made of ordinary stainless steel material, and the homogenizing head can be made of conventional high-hardness material. It has a small size and a simple structure, which reduces the material cost and the processing difficulty, and solves the problem of processing difficulty caused by the strong brittleness of high-hardness materials in the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 It is a front view of a high pressure valve core of the prior art;

[0015] Figure 2 It is a cross-sectional view of the inlaid high-pressure valve core of the utility model.

[0016] In the figure, 1 is a high-pressure valve core, 2 is a homogenizing valve core body, 201 is an inlay groove, 3 is a homogenizing head, and 301 is a material impact surface. DETAILED DESCRIPTION

[0017] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0018] Please see attached Figure 2 A mosaic high-pressure valve core comprises a homogenizing valve core body 2 and a homogenizing head 3; an embedding groove 201 is formed at the end of the homogenizing valve core body 2, so that one end of the homogenizing head 3 is embedded in the embedding groove 201, and the other end of the homogenizing head 3 extends to the outside of the embedding groove 201, forming an embedded high-pressure valve core.

[0019] The prior art monolithic high-pressure valve core is divided into a homogenizing valve core body 2 and a homogenizing head 3. In order to ensure the requirements of wear resistance, corrosion resistance and hygiene, the homogenizing head 3 is made of the same high-hardness material as the prior art monolithic high-pressure valve core. The homogenizing head 3 is small in size and uniform in shape, easy to process, and has low processing cost. The homogenizing valve core body 2 is not impacted by the material and can be made of ordinary stainless steel, which has lower cost and is easy to process.

[0020] The inlay groove 201 is made according to the size adaptability of the homogenizing head 3. Due to the setting of the inlay groove 201, the homogenizing head 3 can be inlaid and assembled on the homogenizing valve core body 2, thereby ensuring that the inlaid high-pressure valve core formed by the homogenizing head 3 and the homogenizing valve core body 2 can have the same structure, size and function as the integral high-pressure valve core in the prior art.

[0021] The inner diameter of the embedding groove 201 is slightly smaller than the outer diameter of the homogenizing head 3 , so that one end of the homogenizing head 3 is interference-fitted in the embedding groove 201 .

[0022] By means of interference fit, the integrity and firmness of the homogenizing head 3 after being assembled with the homogenizing valve core body 2 through the inlay groove 201 are ensured to meet the use requirements of the inlaid high-pressure valve core.

[0023] At the same time, when the homogenizing head 3 is assembled into the inlay groove 201, the temperature difference method can be used for assembly, so as to further improve the assembly quality and service life of the inlaid high-pressure valve core.

[0024] The embedding direction of one end of the homogenizing head 3 in the embedding groove 201 is consistent with the material impact direction, and the other end of the homogenizing head 3 is formed with a material impact surface 301 , and the material impacts on the material impact surface 301 .

[0025] When the material impacts the homogenizing head 3, since the embedding direction of the homogenizing head 3 in the embedding groove 201 is consistent with the material impact direction, not only will the homogenizing head 3 not fall out of the embedding groove 201, but it is also conducive to ensuring the embedding and assembly reliability of the homogenizing head 3 and the embedding groove 201. The material impact surface 301 is used to withstand the impact of the material.

[0026] The shape and size of the inlaid high-pressure valve core are consistent with those of the high-pressure valve core in the prior art, thereby ensuring that the inlaid high-pressure valve core of the utility model can achieve the same use effect as the high-pressure valve core in the prior art.

[0027] The hardness of the homogenizing head 3 is greater than the hardness of the homogenizing valve core body 2 .

[0028] The homogenizing head 3 is made of conventional high-hardness material of the high-pressure valve core, and has relatively high hardness. The homogenizing valve core body 2 can be made of ordinary stainless steel, and has relatively low hardness, so that the homogenizing head 3 can ensure wear resistance and corrosion resistance under the impact of materials.

[0029] At the same time, since the cost and hardness of ordinary stainless steel materials are lower than those of high-hardness materials, the processing cost and difficulty can be reduced.

[0030] Please see attached Figure 2 , the processing method of the utility model is:

[0031] The homogenizing valve core body 2 is made of ordinary stainless steel, and the homogenizing head 3 is made of high-hardness materials such as ceramics, which are the same as the high-pressure valve core in the prior art.

[0032] An inlay groove 201 is reserved at one end of the homogenizing valve core body 2 and the homogenizing head 3, and one end of the homogenizing head 3 is inlaid into the inlay groove 201 by interference fitting and temperature difference method, so that the shape and size of the inlaid high-pressure valve core formed by the homogenizing valve core body 2 and the homogenizing head 3 are consistent with the shape and size of the integral high-pressure valve core in the prior art. The shape and size of the homogenizing valve core body 2 and the homogenizing head 3 are determined according to the shape and size of the conventional integral high-pressure valve core.

[0033] The installation and use method of the embedded high-pressure valve core of the utility model on the homogenizer is the same as the installation and use method of the integral high-pressure valve core on the homogenizer in the prior art, and will not be repeated here.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
