Abstract
The utility model relates to a valve device for the detection of a capillary tube viscosity meter, which comprises a shell body. The utility model is characterized in that a plurality of tube connecting joints which penetrate through the shell body are arranged on the shell body. A rotary valve is arranged in the shell body. The rotary valve is in slide connection with the shell body. An air passage which is communicated with a central air passage is arranged in the rotary valve. An electric switch is arranged at the end part of the rotary valve. Since the utility model adopts the structure, the utility model can carry out detecting operation with one or two viscosity meters (comprising a Wu's, a Ping's and a Kanfen's viscosity meter). The valve device can be installed in a detecting device of an automatic capillary viscosity meter to realize the automation of viscosity detection. The utility model has the advantages of simple operation and high efficiency.
Description
The utility model relates to a kind of valve, specifically relates to a kind of valving that capillary viscosimeter is measured that is used for.
The mensuration draw solution of capillary viscosimeter is to rely on syringe or rubber pipette bulb to draw detected solution to measuring ball, allows the detected solution free flow cross kapillary then, is flow through the viscosity of the required time decision liquid of certain volume liquid by mensuration.In mensuration, need to draw and release gas, need will clamp arm, imbitition earlier for the measurement operation of Ubbelohde viscometer, imitate the spending pipe then and measure pipe, make the liquid of kapillary bottom form a bubble, the flowing down of support liq, eliminate the different influence of liquid volume, complex operation.Also there is same defective for the flat viscosity meter.
The purpose of this utility model just be to provide a kind of simple in structure, easy to operate, automaticity is high is used for the valving that capillary viscosimeter is measured.
The purpose of this utility model can realize by following measure:
The utility model comprises housing, the connecting pipe joint of a plurality of perforation housings is set on housing, be provided with rotating valve in the housing, the end part rotating shaft of rotating valve is provided with knob, between rotating valve and the housing for being slidingly connected, the keeper that is used to control housing and rotating valve relative position is installed between housing and rotating valve, in rotating valve, is provided with the airway that is connected with the center gas circuit, rotating valve be connected with the center gas circuit place the end be provided with the electric switch that is used to control vacuum pump.
Keeper in the utility model is made up of spring and corresponding peripheral hardware steel ball that pilot hole of offering on housing and installation are distributed in the rotating valve, keeper is set is and make that each connecting pipe joint accurately is communicated with the center gas circuit when practical operation, in view of the above, also can adopt other suitable locating device, scale mark etc. is set as correspondence on housing and knob.
Because the utility model adopts mechanisms such as rotating valve, connecting pipe joint, and offers the airway that is connected with the center gas circuit in rotating valve.In view of the above, the utility model can carry out the measurement operation of or two viscosity meters (comprising Ubbelohde, Ping Shi, bank Fen Shi viscosity meter), can be installed in the determinator of automatic capillary viscosimeter, realizes the robotization of viscosimetric analysis, and simple to operate, the efficient height.
Accompanying drawing drawing of the present utility model is described as follows:
Fig. 1 is a front view of the present utility model.
Fig. 2 is the left view of the utility model center gas circuit and pipe adapter 6 Fig. 1 when being connected the position.
Fig. 3 is the left view of the utility model center gas circuit Fig. 1 when communicating the position with atmosphere.
Fig. 4 is the left view of the utility model center gas circuit and pipe adapter 8 Fig. 1 when being connected the position.
Fig. 5 is the left view of the utility model center gas circuit and pipe adapter 9 Fig. 1 when being connected the position.
The utility model is done explanation in further detail below in conjunction with drawings and Examples:
As shown in the figure: the utility model comprises housing 1, a plurality of perforation housings are set on housing 1, be provided with rotating valve 2 in the housing 1, the end part rotating shaft of rotating valve 2 is provided with knob 3, between rotating valve 2 and the housing for being slidingly connected, the keeper that is used to control housing and rotating valve relative position is installed between housing and rotating valve, in rotating valve 2, be provided with the airway that is connected with center gas circuit 5, rotating valve 2 be connected with center gas circuit 5 place the end be provided with the electric switch 4 that is used to control vacuum pump.Keeper is made up of spring and corresponding peripheral hardware steel ball that pilot hole of offering on housing 1 and installation are distributed in the rotating valve.
Principle of work of the present utility model is as follows: the utility model can be realized the suction filtration operation of viscometer determining (as functions such as air blowing mixing, suction sample, mensuration) or liquid.When operating for viscometer determining, as Fig. 2,3, shown in 4: connecting pipe joint 6,7,8 and 10,11,12 are made as one group respectively, two groups can be used individually or simultaneously, thereby carry out a kapillary or two measurement operations capillaceous, each connecting pipe joint connects each capillary exit respectively in every group, when the position of rotating valve at Fig. 1, electric switch is connected, air pump (or vacuum pump) is started working, center gas circuit 5 communicates with pipeline 6 on the housing, pipeline 7 on the housing is closed simultaneously, and connecting pipe joint 8 is carried out the pipe inside and outside air pressure balance, at this moment can realize the operation of a capillary viscosimeter absorption mensuration liquid.When the position of rotating valve at Fig. 3, electric switch opens circuit, and air pump quits work, and pipeline 6 on the housing and 7 open circuits (communicating with atmosphere) are realized the measurement operation of liquid viscosity.Rotating valve is when the position of Fig. 4, electric switch is connected, air pump is started working, center gas circuit 5 communicates with pipeline 8 on the housing, pipeline 7 on the housing is closed simultaneously, at this moment can realize blowing the operation of agitated liquid, this is in the viscosimetric analysis of samples such as grain, for the homogeneity that guarantees liquid is very important.Symmetrical with pipeline with upper shell, designed in addition corresponding pipeline, can realize controlling the operation of second viscosity meter.In order to adapt to the pre-treatment of grain viscosimetric analysis, designed and to have carried out the operation of suction filtration, when operating for the suction filtration of liquid, shown in Fig. 5 position: when the position of rotating valve at Fig. 5, electric switch is connected, air pump is started working, and center gas circuit 5 communicates with pipeline 9 on the housing, at this moment can realize the operation of suction filtration.
