Abstract
The invention relates to a three-passage antibiotic multifunctional valve, which comprises a valve body, a valve cover, a valve rod and a valve core, wherein three fluid passages are arranged on the valve body. The invention adopts a technical scheme that: the upper and lower lines of the longitudinal cross section of each fluid passage are substantially integral arcs which has a reducing height from the inside to the outside; and the fluid passage on the cross section is transitional with a face adjacent to the fluid passage through the arcs. The valve integrates the three fluid passages, is novel in structure, has no dead angle, is good in sealing property and strong in corrosion resistance, and reduces the number of pipeline control valves.
Description
Affiliated technical field
The present invention relates to a kind of three-passage antibiotic multifunctional valve.
Background technique
Three-passage antibiotic multifunctional valve is widely used in industries such as biofermentation, medicine, fine chemistry industry, the conveying that is used in the inoculation distribution station seed liquor of medical bioengineering fermenting tub and culture medium especially is through-flow, by and regulate.
The valve that the special process of biofermentation requires to use on this technology need satisfy do not leak, not microbiological contamination, performance such as tank switching not, otherwise will cause the production bacterium source of valve applications enterprise to pollute and a large amount of wastes of material.In prior biological medicine fermenting and producing, seeding tank divides the adapted valve often all to adopt stop valve, ball valve, membrane valve, be welded to form with pipe fitting, so a plurality of valves not only take up room on same pipeline, more than on the pipeline dead angle and leakage point, increase the frequent blending operation of workman in addition, time-consuming, the waste device resource.
Summary of the invention
The objective of the invention is to overcome the above-mentioned defective of prior art, a kind of three-passage antibiotic multifunctional valve is provided, this valve makes triple channel in one, and novel structure, no dead angle, good seal performance, antiseptic property are strong, and reduces pipeline control valve quantity.
The present invention includes valve body, valve gap, valve rod and spool, valve body is provided with three fluid passages, its technical solution is that the overwhelming majority on two limits up and down of the longitudinal section of described fluid passage is a low inside and high outside complete circular arc, and the face that the fluid passage is adjacent on this cross section carries out transition by circular arc equally.
Do not have flex point and dead angle on the whole process of circulation circuit of antibiotic valve of employing said structure, rapid variation does not take place in flow direction and channel shape, helps flowing of seed liquor and material culture medium.
Further technical solution of the present invention is that described spool comprises flap, the below of flap is provided with the flap double-screw bolt of solid forging, sealing gasket is attached to the flap lower end surface, and sealing gasket being fixed on flap below by baffle plate, set screw nut and cotter pin, the top of flap is fixed on the valve rod below by pressing plate, flap and cap with flap.
The described retaining effect of pulling one is to be adjacent to sealing gasket, the 2nd, prevent that sealing gasket from not blown flange by steam under high-temperature vapour sterilization operating mode, and simultaneously, the cotter pin on the flap double-screw bolt can prevent that set screw nut from coming off because of the vibration that pipe tension and flow of vapor produced.
Further technical solution of the present invention is that the periphery at the lower end surface of flap sealing gasket is provided with the Fixed width boss face.
This Fixed width boss face can effectively prolong the working life of flap sealing gasket and the erosion of excellent sealing performance and surperficial anti-material.
Description of drawings
Further illustrate particular content of the present invention below in conjunction with drawings and Examples.
Fig. 1: the structural representation of present embodiment;
Fig. 2: the partial enlarged drawing of spool part in the present embodiment.
Embodiment
As shown in the figure, present embodiment comprises valve body 1, valve gap 2, valve rod 3 and spool 4, valve body 1 is provided with three fluid passages 11, the overwhelming majority of two limit a, b up and down of 11 longitudinal section is a low inside and high outside complete circular arc in the fluid passage, and the face that the fluid passage is adjacent on this cross section carries out transition by circular arc equally.Described spool 4 comprises flap 41, the below of flap 41 is provided with the flap double-screw bolt 42 of solid forging, sealing gasket 43 is attached to flap 41 lower end surfaces, and sealing gasket 63 being fixed on flap 41 belows by baffle plate 44, set screw nut 45 and cotter pin 46, the top of flap 41 is fixed on valve rod 3 belows by pressing plate 47, flap and cap 48 with flap 41.Periphery at the lower end surface of flap 41 sealing gasket 43 is provided with Fixed width boss face 49.
