Device, and there is flow locking structure.
To achieve the goals above, the technical solution adopted in the utility model is：
A kind of flow regulator, including upper shell and lower housing are equipped with liquid inlet conduit connector in upper shell, are set in lower housing
There are eluate conduit connector, upper shell, lower housing to buckle and be connected with each other by center, can relatively rotate, it is characterised in that：On described
A Gask-O-Seal made of silica gel is fixedly installed on the lower face of shell, gasket is equipped with and liquid inlet conduit fittings
Inlet opening, the upper surface of gasket and lower housing offsets to form sealing cooperation, setting one and sealing on the upper surface of lower housing
Corresponding annular protrusion is padded, the radial width of the protrusion is less than the radial width of gasket, is arranged one on the upper surface of the protrusion
Annular groove corresponding with inlet opening, the annular groove are to disconnect being arranged, and one end is feed flow end, and the other end is outlet end, from confession
The depth of liquid end to outlet end annular groove gradually increases, and outlet end is equipped with the fluid hole with eluate conduit fittings, feed flow
It is locking end face between end and outlet end；Inlet opening, annular groove, fluid hole form infusion channel；The width of the annular groove
Diameter of the degree more than inlet opening.
The utility model is further arranged to, and the annular groove is located at the centre position of protrusion.
The utility model is further arranged to, and the lower face of the upper shell is equipped with the annular groove of placement gasket,
The bottom surface of gasket is arranged less than the bottom surface of lower housing.
The beneficial effects of the utility model：Flow regulator provided by the utility model, gasket and upper surface
It offsets to form sealing cooperation, inlet opening, annular groove, fluid hole form infusion channel, and wherein gasket is surrounded with annular groove
The closed channel of one both ends open is connected to respectively with inlet opening, fluid hole at both ends open.The sealing structure is simple, close
Seal structure will not move, and ensured the stabilization, reliable of infusion, improved the precision of control.And work as inlet opening face locking
When end face, infusion channel can be closed, realizes the locking of flow.

Specific implementation mode
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.
The utility model is illustrated below with reference to Fig. 1 to Fig. 7.
A kind of flow regulator, including upper shell 1 and lower housing 2 are equipped with liquid inlet conduit connector 3, lower housing in upper shell 1
Eluate conduit connector 4 is equipped in 2, upper shell 1, lower housing 2 are buckled by center and are connected with each other, and can relatively rotated, the above skill
Art is the prior art, can be found in the prior art scheme.
Gask-O-Seal 5 made of silica gel are fixedly installed on the lower face of the upper shell 1, gasket 5 is equipped with
The upper surface of the inlet opening 6 being connected to liquid inlet conduit connector 3, gasket 5 and lower housing 2 offsets to form sealing cooperation, lower housing 2
Upper surface on an annular protrusion 7 corresponding with gasket 5 is set, the radial width of the protrusion 7 is radially-wide less than gasket 5
Degree enables protrusion 7 to be pressed on completely on gasket 5, forms good sealing cooperation, on the upper surface of the protrusion 7 setting one and
6 corresponding annular groove 8 of inlet opening, annular groove 8 are located at the centre position of protrusion 7, which is to disconnect being arranged, and one
End is feed flow end 9, and the other end is outlet end 10, and the depth from feed flow end 9 to 10 annular groove 8 of outlet end gradually increases, and goes out liquid
End 10 is equipped with the fluid hole 11 being connected to eluate conduit connector 4, is locking end face 12 between feed flow end 9 and outlet end 10；Feed liquor
Hole 6, annular groove 8, fluid hole 11 form infusion channel；The width of the annular groove 8 is more than the diameter of inlet opening 6.
Protrusion 7 offsets to form sealing cooperation with gasket 5, and liquid is recessed in the closed annular that protrusion 7 is surrounded with gasket 5
It is flowed in slot 8, as upper shell 1 and lower housing 2 relatively rotate, inlet opening 6 is moved along annular groove 8, realizes flow tune
Section realizes that flow blocks locking when inlet opening 6 turns on locking end face 12.
The lower face of upper shell 1 is equipped with the annular groove of placement gasket 5, and the bottom surface of gasket 5 is less than the bottom of lower housing 2
Face is arranged.Since gasket 5 made of silica gel has certain elasticity, in gasket 5 and lower housing upper surface offset cooperation,
Gasket 5, which can be squeezed, occurs certain elastic deformation, makes it to provide better seal ability.
Flow regulator provided by the utility model, gasket 5 and upper surface offset to be formed sealing cooperation, feed liquor
Hole 6, annular groove 8, fluid hole 11 form infusion channel, and wherein gasket 5 surrounds the envelope of a both ends open with annular groove 8
Closed walk is connected to respectively with inlet opening 6, fluid hole 11 at both ends open.The sealing structure is simple, and sealing structure will not occur
It is mobile, it has ensured the stabilization, reliable of infusion, has improved the precision of control.And it when 6 face locking end face 12 of inlet opening, can close
Infusion channel is closed, realizes the locking of flow.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvements and modifications, above-mentioned vacation can also be made
If these improvements and modifications also should be regarded as the scope of protection of the utility model.
