Insignificant volume.Two are, photoemitter and photelectric receiver are positioned at the outside of digestion tube housing, owing to digestion tube needs to add
Heat, and temperature is the most invariable, there is the temperature difference and thermal fluctuation, and photoelectricity is received between digestion tube hull outside and inside
The work sending out device is affected by temperature, so certain fluctuation can be caused.
Utility model content
The purpose of this utility model is the problem existed for prior art, it is provided that a kind of analyser digestion device.
Technical scheme: a kind of analyser digestion device, including housing and the digestion tube being fixed in described housing, feature
It is also to include photoemitter and the photelectric receiver being fixed on case inside, and be fixed on housing and straight with digestion tube
Electromagnetic valve logical in succession；In described digestion tube light path between photoemitter and photelectric receiver.
In further embodiment, described housing includes roof and fixes the side plate being connected, described side plate with described roof
Upper correspondence has through hole, described photoemitter and photelectric receiver and is connected by screw or bolt are fixing with side plate.Described shell
The top of body is provided with electromagnetic valve installation position, and described electromagnetic valve is fixed in this installation position, and the end of electromagnetic valve is with digestion tube even
Logical.
Preferably, described electromagnetic valve includes having 2 with the valve body of upper runner, the sealing that can move up and down in valve body
Part, and control the Electromagnetic Control element of described seal member kinestate；Truncated cone-shaped it is provided with protruding, described circle in described valve body
Bench-type projection has a conical shaped depression, and at least one runner is opened in conical shaped depression；Described seal member has one and institute
State the conical thimble that conical shaped depression is adaptive.The runner being opened in conical shaped depression is feed liquor runner, goes out liquid flow passage openings
In truncated cone-shaped projection roof or sidewall.Described truncated cone-shaped projection is flexible fluorine material, and described cone thimble is rigidity fluorine material.
Described rigidity fluorine material is trifluoro material, and described flexible fluorine material is PTFE.Described seal member is integrally formed with annular
Projection, and it is arranged with anticorrosion back-up ring.
This utility model has the following advantages compared to existing technology: by optoelectronic transceiver device is arranged on the inner side of housing,
It is easy to control its operating temperature, reduces the impact that measurement data is caused by temperature fluctuation, thus improve the accuracy of data；With
Time, electromagnetic valve is directly connected with digestion tube, rather than is connected by connecting tube, and that analyzes material in decreasing digestion tube distributes sky
Between, improve the accuracy of data.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of valve body of the present utility model.
Fig. 3 is the structural representation of this utility model seal member.
Detailed description of the invention
The basic functional principle of digestion tube is, in digestion tube, sample and medicine react, and before and after reaction, color becomes
Changing, also changed by the luminosity of reaction system, this change meets Lambert's law, by measuring the change of luminosity, can obtain
Know the information of needs.
As it is shown in figure 1, digestion device of the present utility model mainly includes top board (roof) 1, side plate 2, photoemitter and light
Electricity receptor 3, the bottom inside digestion device is provided with digestion tube fixing hole 4.Unlike the prior art, at this utility model
In, photoemitter and photelectric receiver are fixed on the inner side of housing, rather than outside.It is operationally to close due to housing,
So its internal temperature can be stable control, reduce the fluctuation of temperature, and then reduce the ripple of optoelectronic transceivers measurement data
Dynamic property, it is hereby achieved that stable, data the most accurately.On the other hand, the top of housing is provided with electromagnetic valve installation position,
Electromagnetic valve can be fixedly mounted on housing, and the end of electromagnetic valve directly connects with digestion tube.Without using communicating pipe to connect, enter
And decrease analyze material in digestion tube distribute space, decrease the loss of material, thus in ensureing digestion tube, analyze material
The accuracy of concentration, decreases analytical control error.
Technical essential and the operation principle of electromagnetic valve are described in conjunction with Fig. 2 and Fig. 3.The critical piece of electromagnetic valve include valve body,
Seal member and control parts, valve body offers the runner of liquid communication, and seal member is used for sealing runner, controls parts and uses
In the state controlling seal member.Control parts effect under, seal member can move in valve body, thus seal runner or
Person connects runner.In general, electromagnetic control components can be used to control the kinestate of seal member.Such as it is socketed with spring
On seal member, the other end of spring abuts with iron core, and after electromagnetic unit energising, after being mentioned by iron core, spring moves, thus
Pressure on seal member diminishes, and liquid also circulates.When iron core moves to the direction of seal member, on seal member and valve body
Valve seat be in close contact, cut off the connection between runner, close electromagnetic valve.
Different from the sealing means of the plane that prior art uses or planar band annular protrusion.This utility model uses round platform
Shape pedestal and the fit system of cone sealing member.As shown in Figures 2 and 3, the central authorities of valve body 51 have a coaxial circular platform type
Protruding 53, this circular platform type projection has the cone coaxially stood upside down or a truncated cone-shaped depressed part 54, the bottom of depressed part has
One feed liquor runner 55.Go out liquid stream road to be opened on the roof that truncated cone-shaped is protruding.This valve body is additionally provided with the second seal convexity or
Depression 52, for touching with back-up ring, forms secondary sealing area.
Seal member is broadly divided into integrated three parts, i.e. cone thimble portion 57, annular protrusion 58 and cylinder
Push rod 56.Cone thimble is adaptive with the depressed part of cone or truncated cone-shaped, when it moves to depressed part, forms a sector
Face, compared with the plane of prior art, its contact area is bigger, and sealing effectiveness is more preferable.Cylindrical push rod can be socketed with spring,
Under the control of electromagnetic control components, seal member moves toward and away from depressed part, thus disconnects or connect runner.
In a still further embodiment, truncated cone-shaped projection is flexible fluorine material, such as PTFE.Cone thimble is
Rigidity fluorine material, such as trifluoro material.When thimble clashes into protruding, there is certain replied deformation between the two, thus keep away
Exempt from rigid objects and collide the damage caused.If there being short grained impurity between the two, by elastic deformation, sealing effectiveness is more
Good, simultaneously can also antibody Monoclonal, extend the service life of electromagnetic valve.
