Description

Technical Field

[0001] The utility model relates to the technical field of homogenizer accessories, in particular to a rounded cone valve seat. Background Art

[0002] The one-way valve seat of the homogenizer generally adopts a cone valve seat, that is, a valve seat structure with a conical shape, as shown in the attached Figure 1 As shown, the top and bottom of the cone valve seat 1 are both formed with a 45° chamfer structure 101. When installing, it is necessary to hammer the top of the cone valve seat to make it match and fit with the conical surface of the inner hole of the pump body. When disassembling, it is necessary to hammer the bottom of the cone valve seat to separate it from the conical surface of the inner hole of the pump body.

[0003] Since the direction of the hammering is difficult to control, it is inevitable that the cone valve seat will tilt at a certain angle. And because the top and bottom of the cone valve seat are chamfered, the edges of the chamfers are sharp. Once the cone valve seat tilts in the inner hole of the pump body, the chamfers will cause rubbing and wear on the inner hole of the pump body, thereby causing damage to the cone valve seat and the pump body. Therefore, it is necessary to provide a cone valve seat with rounded corners, which can solve the problem in the prior art that the cone valve seat easily rubs against the inner hole of the pump body during disassembly and assembly, causing damage to the cone valve seat and the pump body. Summary of the invention

[0004] The utility model aims to provide a cone valve seat with rounded corners, which can solve the problem in the prior art that the cone valve seat easily rubs against the inner hole of the pump body during disassembly and assembly, thus causing damage to the cone valve seat and the pump body.

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

[0006] A cone valve seat with rounded corners comprises a cone valve seat body, a first rounded corner is formed at the top edge of the cone valve seat body, and a second rounded corner is formed at the bottom edge of the cone valve seat body, so that when the cone valve seat body is embedded in the inner hole conical surface of a pump body, the cone valve seat body is in smooth contact through the first rounded corner and the second rounded corner.

[0007] The height of the cone valve seat body is smaller than the height of the inner hole cone surface of the pump body, so that the lower end of the cone valve seat body is flush with the lower end of the inner hole cone surface, and the upper end of the cone valve seat body is lower than the upper end of the inner hole cone surface.

[0008] The diameter of the big end of the inner hole cone surface of the pump body is consistent with the diameter of the upper cylindrical surface of the inner hole of the pump body, and the diameter of the big end of the inner hole cone surface of the pump body is larger than the diameter of the big end of the cone valve seat body, so that an anti-collision gap is formed between the big end of the cone valve seat body and the upper cylindrical surface of the inner hole of the pump body.

[0009] The first fillet and the second fillet both include a first connecting fillet connected to the cone surface of the cone valve seat body, a second connecting fillet connected to the plane of the cone valve seat body, and a chamfered surface connected between the first connecting fillet and the second connecting fillet.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] 1. The utility model has a first rounded corner and a second rounded corner, so that the cone valve seat and the inner hole of the pump body have a softer sliding contact during the disassembly and assembly process, thereby avoiding the collision of the sharp chamfered part of the prior art with the inner hole of the pump body, thereby reducing the damage rate of the cone valve seat and the pump body, extending the service life of the cone valve seat and the pump body, and being easy to process and manufacture.

[0012] 2. The height of the cone valve seat of the utility model is slightly smaller than the height of the cone surface of the inner hole, and a first fillet is formed at the top edge of the cone valve seat, so that the maximum diameter of the cone valve seat is smaller than the diameter of the upper cylindrical surface of the inner hole of the pump body, and an anti-collision gap is formed between the cone valve seat and the inner hole of the pump body, thereby further reducing the probability of the cone valve seat rubbing against the inner hole of the pump body during disassembly and assembly, thereby avoiding damage to the cone valve seat and the pump body.

DETAILED DESCRIPTION

[0018] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] Please see attached Figure 2 and attached Figure 3 A cone valve seat with rounded corners includes a cone valve seat body 2, a first rounded corner 201 is formed at the top (large head end) edge of the cone valve seat body 2, and a second rounded corner 202 is formed at the bottom (small head end) edge of the cone valve seat body 2, so that when the cone valve seat body 2 is embedded in the inner hole conical surface 301 of the pump body 3, the cone valve seat body 2 is in smooth contact through the first rounded corner 201 and the second rounded corner 202.

[0020] By setting the first rounded corner 201 and the second rounded corner 202, sharp parts on the cone valve seat body 2 are avoided, thereby reducing the friction with the inner hole of the pump body 3 when the cone valve seat body 2 is tilted, thereby reducing the damage to the cone valve seat body 2 and the pump body 3. Compared with the cone valve seat with a chamfered structure in the prior art, the utility model can extend the service life of the cone valve seat body 2 and the pump body 3.

[0021] In the pump body 3, the inner hole is composed of three parts, including the inner hole cone surface 301 in the middle, the inner hole upper cylindrical surface 302 connected to the large end of the inner hole cone surface 301, and the inner hole lower cylindrical surface 303 connected to the small end of the inner hole cone surface 301, wherein the inner hole cone surface 301 is used to assemble the cone valve seat body 2. The structure of the pump body 3 is the conventional structure of the homogenizer pump body, which will not be repeated here.

[0022] Please see attached Figure 3 and attached Figure 4 The height of the cone valve seat body 2 is slightly smaller than the height of the inner hole cone surface 301 of the pump body 3, so that the lower end of the cone valve seat body 2 is flush with the lower end of the inner hole cone surface 301, and the upper end of the cone valve seat body 2 is lower than the upper end of the inner hole cone surface 301.

[0023] The inclination of the conical surface of the cone valve seat body 2 is consistent with the taper of the inner hole conical surface 301 to ensure the matching assembly of the cone valve seat body 2 in the inner hole conical surface 301, and because the height of the cone valve seat body 2 is reduced, the upper end of the cone valve seat body 2 is lower than the upper end of the inner hole conical surface 301 after assembly, which can reduce the probability of the cone valve seat body 2 colliding with the inner hole of the pump body 3 during installation and disassembly.

[0024] Please see attached Figure 3 and attached Figure 4 The diameter of the big end of the inner hole cone surface 301 of the pump body 3 is consistent with the diameter of the inner hole upper cylindrical surface 302 of the pump body 3, and the diameter of the big end of the inner hole cone surface 301 of the pump body 3 is slightly larger than the diameter of the big end of the cone valve seat body 2, so that an anti-collision gap is formed between the big end of the cone valve seat body 2 and the inner hole upper cylindrical surface 302 of the pump body 3.

[0025] Since the height of the cone valve seat body 2 is smaller than the height of the inner hole cone surface 301, the diameter of the large end of the cone valve seat body 2 is smaller than the diameter of the large end of the inner hole cone surface 301, that is, the diameter of the upper cylindrical surface 302 of the inner hole, and due to the setting of the first fillet 201, the large end diameter of the cone valve seat body 2, that is, the maximum diameter, is further reduced, so that the maximum diameter of the cone valve seat body 2 is smaller than the diameter of the upper cylindrical surface 302 of the inner hole, thereby forming an anti-collision gap between the cone valve seat body 2 and the upper cylindrical surface 302 of the hole, which is used to reduce the probability of collision between the cone valve seat body 2 and the inner hole of the pump body 3.

[0026] The width L of the anti-collision gap can be adaptively adjusted according to actual assembly requirements.

[0027] Please see attached Figure 4 The first fillet 201 and the second fillet 202 both include a first fillet R1 connected with the conical surface of the cone valve seat body 2, a second fillet R2 connected with the plane of the cone valve seat body 2, and a chamfered surface 203 connected between the first fillet R1 and the second fillet R2.

[0028] During processing, only the two ends of the chamfered structure 101 on the cone valve seat 1 of the prior art and the chamfered sharp parts where the cone surface and the plane of the cone valve seat 1 are connected are made into rounded structures to form a first connecting rounded corner R1 and a second connecting rounded corner R2, which is easy to process and manufacture.

[0029] Please see attached Figure 2 To Attachment Figure 4 , the working principle of the utility model is:

[0030] During installation, the top of the cone valve seat body 2 is hammered to make it fit downward into the inner hole cone surface 301 of the pump body 3. The lower end of the cone valve seat body 2 is flush with the lower end of the inner hole cone surface 301. Since the height of the cone valve seat body 2 is less than the height of the inner hole cone surface 301, the upper end of the cone valve seat body 2 is lower than the upper end of the inner hole cone surface 301 after assembly.

[0031] During the installation process, if the cone valve seat body 2 is tilted at a certain angle due to the inclination of the hammering direction, it can smoothly slide in contact with the inner hole surface of the pump body 3 through the first rounded corner 201 and the second rounded corner 202, thereby avoiding the sharp chamfers of the prior art from colliding with the inner hole of the pump body 3, thereby preventing damage to the cone valve seat body 2 and the pump body 3.

[0032] During disassembly, the bottom of the cone valve seat body 2 is hammered to make it upwardly disengage from the inner hole cone surface 301 of the pump body 3. Since the height of the cone valve seat body 2 is less than the height of the inner hole cone surface 301, that is, the maximum diameter of the cone valve seat body 2 is less than the diameter of the inner hole upper cylindrical surface 302 of the pump body 3, the maximum diameter of the cone valve seat body 2 is located on the inner side of the inner hole upper cylindrical surface 302 of the pump body 3, and a gap of width L is left between the large end of the cone valve seat body 2 and the inner hole upper cylindrical surface 302, thereby greatly reducing the friction between the cone valve seat body 2 and the inner hole of the pump body 3 due to the tilt. Even if the cone valve seat body 2 rubs against the inner hole of the pump body 3, the wear on the inner hole of the pump body 3 can be greatly reduced by the first fillet 201 and the second fillet 202, thereby ensuring the service life of the cone valve seat body 2 and the pump body 3.

[0033] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection 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 scope of protection of the present invention.
