Description

Referring to fig. 1, the prior art homogenizing valve mainly includes a plunger 100, a homogenizing valve core 200, a homogenizing valve seat 300, a collision ring 400, a valve body 500, etc., the homogenizing valve seat 300 is tightly pressed in the valve body 500 through a sealing ring 600, and is located at a material inlet, and the collision ring 400 is coaxially pressed on the homogenizing valve seat 300 through an inner step of the valve body 500. When in use, under the action of the axial thrust of the mandril 100, one end of the homogeneous valve core 200 is arranged in the collision ring 400 in parallel and is tightly closed with the valve surface of the homogeneous valve seat 300. The material pushes the homogenizing valve core 200 away in a high-pressure fluid state and overflows at a high speed through the valve surface, the larger the thrust applied by the ejector rod 100 is, the higher the pressure required by the material for pushing the valve surface is, and the faster the flow speed of the material overflowing from the valve surface is, the better the shearing effect, the collision effect and the cavitation effect are correspondingly played, and the better the homogenizing effect is.

The material impacts the valve face of the homogenizing valve seat and the inner wall of the collision ring in a high-pressure fluid state, so that the valve face of the homogenizing valve seat and the inner wall of the collision ring are abraded, the homogenizing effect is accordingly weakened, and meanwhile the service life of parts in the homogenizing valve is correspondingly shortened.

Detailed Description

The utility model is further described with reference to the following figures and specific examples.

Referring to fig. 2 and fig. 3, a shear type homogenizing valve for a homogenizer comprises a mandrel 100, a homogenizing valve core 200, a valve body 500 and an integrated homogenizing valve seat 1; the integrated homogeneous valve seat 1 is installed in the valve body 500 through a seal ring 600 and is pressed and fixed through an inner step of the valve body 500, a material channel 11 is formed in the integrated homogeneous valve seat 1, one end of the material channel 11 is communicated with a material inlet 501 of the valve body 500, and the other end of the material channel 11 is communicated with a material outlet 502 of the valve body 500; the homogeneous valve core 200 is axially and tightly installed in the valve body 500 through the ejector rod 100, the butt end of the homogeneous valve core 200 is abutted to the ejector rod 100, the other end of the homogeneous valve core 200 is a shearing cone 201, and the small end of the shearing cone 201 with a conical structure is installed in the material channel 11, so that the conical surface of the shearing cone 201 and the conical surface in the integrated homogeneous valve seat 1 are always kept in a tightly closed state. Because the ejector rod 100 tightly pushes the homogeneous valve core 200, the conical surface of the shearing cone 201 can be pushed in under the thrust action of the ejector rod 100 after being worn, so that the homogeneous valve core 200 and the integrated homogeneous valve seat 1 are always tightly pushed and sealed, and the homogeneous effect of materials is ensured.

The diameter of the material passage 11 is smaller than the diameter of the large head end of the shearing cone 201 and larger than the diameter of the small head end, so that the small head end of the shearing cone 201 can be installed on the inner side of the material passage 11, and the large head end of the shearing cone 201 is located outside the material passage 11. The small end of the shearing cone 201 is arranged in the material channel 11, the tight sealing of the shearing cone 201 and the integral type homogenizing valve seat 1 is guaranteed, and the length of the large end of the shearing cone 201 can provide reliable guarantee for the automatic compensation of the abrasion gap between the shearing cone 201 and the integral type homogenizing valve seat 1.

A homogenizing collision step 12 is formed at the other end of the material channel 11, and the other end of the material channel 11 is communicated with a material outlet 502 through the homogenizing collision step 12; a portion of the conical surface of the shear cone 201 is located within the homogeneous collision step 12. The homogeneous collision step 12 can improve the collision effect of the material and improve the homogeneous effect.

The joint of the material channel 11 and the homogeneous collision step 12 is formed with a valve seat conical surface 13, and the conical surface of the shear cone 201 is abutted and sealed with the valve seat conical surface 13, so that the small end of the shear cone 201 is coaxially installed in the material channel 11. The conical surface 13 of the valve seat is sharp, so that the tight sealing of the shearing cone 201 and the integral homogeneous valve seat 1 is ensured, the material is conveniently guided into the homogeneous collision step 12 from the material channel 11, and the homogeneous effect is further improved.

The diameter of the homogeneous collision step 12 is slightly larger than that of the homogeneous collision valve core 200, and when the shearing cone 201 abuts against the valve seat conical surface 13, the conical surface of the shearing cone 201 is positioned on the inner side of the homogeneous collision step 12, so that sufficient overflow space for materials is ensured.

The shear cone 201 and the homogeneous valve core 200 are coaxially arranged, the shear cone 201 and the homogeneous valve core 200 are of an integrated structure, the processing and the manufacturing are easy, and the motion coaxiality of the homogeneous valve core 200 is also ensured.

Preferably, the integrated homogeneous valve seat 1 may be made of a corrosion-resistant hard alloy material having a relatively high hardness, and the shear cone 201 and the homogeneous valve core 200 may be made of a stainless steel material having a relatively low hardness than the integrated homogeneous valve seat 1.

The working principle of the utility model is as follows:

along the arrow direction shown in fig. 2, the material enters the material channel 11 of the integrated homogeneous valve seat 1 through the material inlet 501 in a high-pressure fluid state, pushes the homogeneous valve core 200 along the axial direction of the shearing cone 201 of the homogeneous valve core 200, and extrudes at high speed from the valve seat conical surface 13 of the sharp integrated homogeneous valve seat 1 to overflow the material outlet 502, so that the material achieves a high-speed shearing effect, a collision effect and a cavity effect.

When the homogenizing valve is in a high-pressure working state for a long time, once a gap is generated between the conical surface of the shearing cone 201 and the conical surface 13 of the valve seat due to abrasion of materials, because the ejector rod 100 always keeps an axial jacking state for the homogenizing valve core 200, the conical surface of the shearing cone 201 is synchronously jacked in an axial direction, the sealing jacking state between the conical surface of the shearing cone 201 and the conical surface 13 of the valve seat is always kept, the abrasion gap is compensated, so that the conical surface 13 of the valve seat always keeps a pressing sealing state, the homogenizing effect of the materials is further ensured, and the homogenizing effect cannot be weakened due to the gap generated by abrasion of the conical surface of the shearing cone 201 and the conical surface 13 of the valve seat. Meanwhile, the clearance between the conical surface of the shearing cone 201 and the conical surface 13 of the valve seat can be automatically compensated through the jacking of the ejector rod 100, and further the service life of parts of the homogenizing valve is prolonged.

The present invention is not limited to the above embodiments, and therefore, any modifications, equivalents, improvements, etc. within the spirit and principle of the present invention should be included in the scope of the present invention.
