Abstract
The present invention discloses a combined constant-gap homogeneous valve which belongs to the range of a precise machine valve. The annular end surface of a cylindrical valve body is graved with a plurality of ditch grooves with identical cross sections in a radial mode, the ditch grooves are not mutually communicated, and the ditch grooves are communicated with the surfaces of an inner periphery and an outer periphery. A valve core is applied to the annular end surface of the valve body, and a plurality of valve holes with fixed size are formed after the valve core is pressed by outer force. When large treatment flux is needed, the number of the ditch grooves can be increased, or the width of the ditch grooves is increased when the number of the ditch grooves is decreased. When the valve holes are blocked, the valve body can be separated from the valve core, and the ditch grooves are cleaned. After the ditch grooves are abraded, the annular end surface of the valve body can be burnished for a second ditch groove graving process. The combined constant-gap homogeneous valve can effectively convert pressure energy into crushing energy, and the combined constant-gap homogeneous valve has the advantages of homogeneous treatment efficiency, simple valve structure, convenient machining and cleaning process, capability of the restoration of the valve body and the valve core and low operating cost.
Description
Technical field
The invention belongs to precision optical machinery valve scope, particularly a kind of combined type is decided the crack homogenizing valve.
Background technology
For two kinds of immiscible liquid liquid phase materials being mixed or making insoluble colloidal substance be scattered in the liquid phase material and multiple liquid phase, colloid material are mixed mutually, except that grinding and stirring, generally take to increase high-pressure homogeneous operation, to guarantee that component is even on the mixed liquid material microcosmic.
High-pressure homogeneous is to force liquid material at a high speed by the microgap homogenizing valve with high pressure, relies on multiple actions such as shearing, friction, bump and hole concussion, the broken and mixing with material.Existing homogenizing valve mainly contains and becomes plane, crack valve and decide two kinds on crack micropore valve.Become plane, crack valve and be combination valve, influence is pressed in its gap material feeding, and material presses fluctuation to cause the aperture shakiness of valve, thereby causes the velocity gradient of the liquid flow section of the valve of flowing through to change, and causes pressure can change crushing energy effectively into, finally influences homogenizing effect.Deciding crack micropore valve is the one valve, although can realize that pressure can be to effective conversion of crushing energy, and profound and subtle hole processing difficulties, easily stifled, the difficult cleaning in hole can not be repaired after the valve opening wearing and tearing, and valve is shorter service life, the operating cost height, production capacity is low.
Summary of the invention
The purpose of this invention is to provide a kind of combined type and decide the crack homogenizing valve, inserting valve body by spool combines, it is characterized in that: on the annular end face of tubular valve body, be to carve radially from interior Zhou Huanzhuan end face and have the N bar groove of identical section to the periphery annular end face, N bar groove is not communicated with mutually; Spool inserts valve body, and spool and valve body annular end face are fitted and compressed the back by external force and form some valve openings with fixed dimension, separable valve body, spool when valve opening stops up, cleaning groove.After the groove wear, can polish the heavy ditch groove of valve body annular end face.
Described N is 3-20; When the big processing flux of needs, can increase number of grooves or increase groove width, reduce quantity but guarantee that the degree of depth is constant.
The width of described groove and the degree of depth are micron order.
Beneficial effect of the present invention: pressure can change crushing energy into effectively; Can easily form profound and subtle hole; Realize that single valve has high breaking capacity and big production capacity simultaneously; The treatment effect equilibrium; Valve arrangement is simple, easy to process; Valve cleans convenient; After the groove wear, can polish the heavy ditch groove of valve body annular end face; Valve body, spool all can be repaired, and operating cost is low.

The specific embodiment
The present invention is that a kind of combined type is decided the crack homogenizing valve.On the annular end face of tubular valve body 1, be from interior Zhou Huanzhuan end face and carve the 3-20 bar radially and have identical section to the periphery annular end face, 3-20 bar groove 3 is not communicated with mutually; Spool 2 inserts valve bodies 1, and spool 2 is fitted with valve body 1 annular end face, and compresses the back valve opening (as shown in Figure 1 and Figure 2) that the 3-20 bar has fixed dimension that forms by external force.When the big processing flux of needs, can increase groove 3 numbers; Also can under the prerequisite that guarantees groove 3 degree of depth, increase the width of groove 3, reduce the quantity (as shown in Figure 3) of groove 3.When valve opening stops up, separable valve body 1, spool 2, cleaning groove 3.After groove 3 wearing and tearing, can polish the heavy ditch groove 3 of valve body 1 annular end face.
The present invention can make the pressure of homogenizer can change crushing energy effectively into; Can easily form the uniform profound and subtle hole of section, the treatment effect equilibrium; Realize that single valve has high breaking capacity and big production capacity simultaneously; Valve arrangement is simple, processing, clean convenient; Valve body, spool all can be repaired, and operating cost is low.
Claims (2)
1. a combined type is decided the crack homogenizing valve, inserting valve body by spool combines, it is characterized in that: on the annular end face of tubular valve body, from interior Zhou Huanzhuan end face be carve radially have identical section, to the N bar groove of periphery annular end face, N bar groove is not communicated with mutually; Spool and valve body annular end face are fitted and are compressed the back by external force and form the valve opening that the N bar has fixed dimension, and valve body and spool are separable.
2. decide the crack homogenizing valve according to the described combined type of claim 1, it is characterized in that: described N is 3-20.
