The invention relates to the field of veterinary obstetrics, particularly to tools used for the diagnosis of mastitis in cows using liquid diagnostic reagents.

For the diagnosis of mastitis use dairy-control device, representing the plate with handle and four nests in holes on its smooth surface (number of quarters of the udder). In wells named device they milk the milk from the corresponding quarter of the udder, add 1 ml of liquid diagnostic reagent (2%solution of masticina or 5%solution of dimattina) and the contents stirred with a glass rod. The change in consistency and colour mixture of milk and reagent indicates the presence of mastitis. Solutions liquid diagnostic reagents in the wells dairy-control device make, using dispensers of various designs (resurrection P.I. Technology laboratory works. M.: Chemistry, 1969, p.100).

The closest technical solution is a device for dispensing a liquid containing container (bottle) for liquid diagnostic reagent attached to the cap dispenser, the casing of which is placed the metering chamber, communicating with inlet capacity (bottle) and having an outlet with drain tubes (Ed. mon. 1782487, CL is 01 J 7/00, G 01 F 11/00).

Compressing the vessel wall (bottle), liquid diagnostic reagent of it is served inside and fill the metering chamber. Stop squeezing of the walls, cracking down, they build up in the tank negative pressure, under the influence of something from the chambers of the dispenser is sucked out the excess liquid diagnostic reagent back into the tank. The camera remains on 1 ml. Capacity tilt, giving the ends of the drain tubes in the wells dairy-control device. The reagent of the metering chambers of the dispenser flows into the hole. Remaining in the drain tubes part of reagent is removed by the air flow, arising from the compression of the rubber balloon on the cover of the dispenser. The disadvantage of this device is:

a) inconvenience in the work, as for mixing in the hole of the liquid diagnostic reagent and milk it is necessary to use additional equipment, in particular a glass wand;

b) in the study of milk from one quarter of the udder (they milk only in one hole milk control device) reagent of capacity will be added in the wells, in which the milk was not nazivalos.

The problem to which the invention is directed, and the technical result from its use are concerned with generating device, convenient and increase the efficient use of the liquid diagnostic reagent is in the detection of mastitis.

The technical result is achieved in that the device for dispensing fluid, primarily liquid reagents in the diagnosis of mastitis containing liquid diagnostic reagent attached to the cap dispenser with metering chambers inside the dosing chamber is located between the belts dvuhpotokovogo cylindrical slide valve placed in the longitudinal channel of the body, and at the end of the longitudinal channel installed additional capacity from an elastic material, soamsawali metering chamber of the valve in the position of release from it metered dose of fluid. While the spool in the longitudinal channel is spring-loaded in the direction of the initial position at which its metering chamber communicated with the inlet hole.

On the one end side dvuhosnovnyj the valve is preloaded by the spring 11, the other end has a push rod 12, the diameter of which is 1 mm smaller holes swallowing edge of the common housing 1. The belts slide on the cylindrical surface have two grooves for the sealing rings 13. The inlet 9 is held in the tube and communicated with the bottle 3, the outlet 10 is located diametrically opposite the inlet 9 and is displaced along the wall for a distance greater than the diameter of the holes for alternately opening and closing the inlet 9 and outlet 10 holes when driving dvuhpotokovogo spool 7. To the outlet 10 is connected a drain pipe 14, which end the end is made at an acute angle relative to its axis. The tube is given a measured portion of liquid diagnostic reagent, moreover, it serves as a tool for stirring the mixture of milk and liquid diagnostic reagent. Inside wall of the housing 1 on the side of its attachment to the cover 2 is made longitudinally located air groove 15. It starts from that part of the wall, which is located diametrically opposite the outlet 10 and continues to the end edges of the housing 1.

FIELD: the invention refers to means of batching.

SUBSTANCE: the invention may find application for example in systems of water treatment, in chemical and petrochemical industry and also at extraction and transportation of oil and gas. The invention is directed on creation of a simple and reliable construction of a batcher and at increasing of accuracy of batching of the reagent. The batcher for liquid reagents has a container for the reagent and an arrangement for taking-off of the dynamic head located in the main flow. The arrangement for taking off of the dynamic head is fulfilled in the shape of a ball with two openings located at an angle to each other and communicant with the container for the reagent by means of two connecting tubes. The ball is executed with possibility of turning around the axis perpendicular to the direction of the main flow and the axis of one the openings coincides with the axis of rotating of the ball. For calibrating of the consumption of the reagent the batcher may have additionally an arrangement located on one of the tubes between the container for the reagent and the arrangement for taking-off of dynamic head. At streamlining of the ball by the main flow between the two openings located at an angle to each other an overfall of pressure occurs. It is directly connected with the consumption of the medium in the main flow. At the expense of that overfall of pressure reagent out of the container with which the openings are communicant by means of two connecting tubes comes in the main flow through the opening with lesser pressure. Through the opening with greater pressure the medium comes from the main flow into the container and replaces the reagent in the container.

EFFECT: the invention increases the accuracy of batching the reagent.

FIELD: chemical engineering.

SUBSTANCE: batcher comprises tank and pipeline connected with the tank through two pipes. The pipeline is made of an arc. One connecting pipe is in communication with the outer side of the arc, and the other connecting pipe is in communication with the inner side of the arc. When the fluid flows through the arc-shaped pipeline, the fluid undergoes the centrifugal force directed from the inner side of the arc to its outer side. Since one of the connecting pipes is in communication with the outer side of the arc, and the other connecting pipe is in communication with the inner side of the arc, a pressure drop occurs between the connecting pipes. The pressure drop depends on the flow rate of fluid in the pipeline and causes the reagent to flow from the tank to the pipeline through the connecting pipe, which is in communication with the inner side of the arc. The fluid enters the tank through the connecting pipe, which is in communication with the outer side of the arc, and displaces the reagent from the tank.

EFFECT: enhanced accuracy of batching.
