A sampling device is known, including a container for a fluid medium, having a first end and a second end, equipped with an inlet pipe for introducing fluid at its first end and an outlet pipe for outputting fluid at its second end, a housing, and a bracket configured to fastening the container to the body using wing nuts (https://perma.ss/TX5H-ZM84).

The disadvantages of the known technical solution, preventing the achievement of the technical result mentioned below, are that in order to separate the sampling container, it is necessary to unscrew the wing nuts.

Utility Model Disclosure

The objective of this utility model is to create a device for sampling a fluid medium, which has a combination of the following qualities:

the ability to quickly install and remove the sample container;

no need to fasten the container with latches, locks or threaded connections;

protection of the container from impacts and negative environmental factors.

The technical result of the utility model is to provide a quick-release container for sampling.

The above problem is solved due to the fact that the proposed device for sampling the fluid contains

a container (3) for a fluid medium, having a first end and a second end, provided with an inlet pipe for introducing fluid at its first end and an outlet pipe for outputting fluid at its second end,

rollers (4) rotatable about the longitudinal axis of said container (3) and placed at said first and second ends of container (3),

a body (2) having a first end and a second end, back and side walls, as well as an internal cavity for accommodating said container,

mutually parallel guide plates (1) provided with shaped grooves installed near said first and second ends of said body (2),

in which the said shaped grooves and rollers (4) are made in such a shape that they ensure the fixation of the container (3) from movement along its longitudinal axis and the prevention of spontaneous separation of the said first and second ends of the container (3) from the guide plates (1).

As it will be clear to a specialist in this field of technology, the task is solved due to the totality of the features of the device, while the above technical result is achieved mainly by excluding snap-on and other similar elements from the design, without compromising the reliability of fixing the container, which (reliability) provided by the use of guide plates and rollers.

In the following, the aforementioned device, described in general categories, is explained by way of example of some particularly preferred embodiments that provide additional advantages.

As will be understood by a person skilled in the art, when a shut-off valve is opened, for example, in the process of gas extraction, a reactive force can occur in the container, directed along its axis. In this regard, in order to avoid movement of the container, it is necessary to ensure its fixation from longitudinal movements. Such fixation in the device is provided due to the fact that the container through the rollers interacts with the grooves of the guide plates, which are fixedly fixed on the body.

The rollers can be prevented from moving off the edge of said groove in various ways, for example, by narrowing the rollers in the middle part (the edge of the groove is in contact with the middle part of the roller, while the wider parts prevent the roller from moving along the axis of rotation), or by using flanges (in this case the surface of the roller may be cylindrical). Thus, in one of the preferred embodiments, the rollers (4) are tapered in the middle part, or, alternatively, each of said rollers (4) can be provided with at least one flange.

In addition to fixing the container from movements in the longitudinal direction, it is also necessary to ensure the fixation of the container during its installation and removal from the container, and it is desirable that such fixation be provided both in the vertical and in the horizontal position of the body. At the same time, as mentioned above, such fixation should be as fast as possible, i.e. without the need for latches, locks, screw connections, etc. This result can be achieved by selecting the shape of the groove.

In one of the preferred embodiments of the device described above, spontaneous separation of said first and second ends of the container (3) from said guide plates (1) is ensured by the fact that the shape of said groove is curved.

In a more preferred embodiment of the device described above, said groove has the shape of an arc of a circle.

In an even more preferred embodiment of the device described above, said groove has a helical shape.

In an even more preferred form of execution of the device described above, the separation of the said first and second ends of the container (3) from the guide plates (1) is ensured by the fact that the said groove provides at least a two-fold change in the direction of movement of the rollers (4) in the plane of the guides. plates (1) relative to the groove entrance as they move from the groove entrance to the position furthest from the groove entrance. It is obvious that if on the trajectory from the beginning to the end of the groove the roller changes the direction of motion several times relative to the beginning of the groove, in this case it is excluded from falling out of the groove under the action of a force acting in one direction, in particular, under the action of gravity.

In one of the preferred embodiments of the device described above, the side surface of said container is cylindrical.

For ease of extraction and/or carrying, the container (3) can be additionally equipped with a handle for gripping by hand, attached to its side surface.

Shut-off valves can be placed both on the supply / discharge lines, and can be part of the tank associated with it by assembly operations. In one of the preferred embodiments of the device described above, said pipes are additionally provided with shut-off valves so that the container with the sample can be separated from the inlet and outlet lines together with the shut-off valves (in the closed state).

Due to the presence of side walls, the body of the device has the shape of a niche, which provides additional passive safety during operation. The housing also protects the pressurized container and valves from external mechanical influences and damage.

In one of the preferred embodiments of the device described above, said body (2) is provided with a perforation made with the possibility of detachable fastening of said guide plates (1) at different distances from each other. This makes it possible to use the same housing for mounting containers of different lengths.

Said fluid may be any, however, it is preferably a gas or a liquid.

Any suitable material may be used for the manufacture of the body, container and/or rollers, preferably metal.

The device described above is intended for spot sampling of fluid from a process, main line or tank. The device is preferably used in the oil and gas, chemical industries.

The design of the device provides various mounting options during operation. The device can be installed (both vertically and horizontally) on a vertical rack, wall, metal structure or in various types of cabinets: protective or all-weather heated, both explosion-proof and non-explosion-proof.

It must be understood that in this text the design is characterized only by such features that are sufficient to solve the problem, implement the purpose and achieve the selected technical result; a special mention of all without exception the features and utility characteristics of the device is not required if specialists should know that products of the same kind have such features and utility characteristics and without them the main purpose is not realized; Moreover, it is not required to limit the generalized features to any specific options, if they should be known to specialists and (or) can be selected according to known rules.

The design and use of the device is clearly illustrated by figures 1-3 on the example of private and specific embodiments.

Implementation of the utility model

As shown in FIG. 1 fluid sampling device contains

a container (3) for a fluid medium, having a first end and a second end, provided with an inlet pipe for introducing fluid at its first end and an outlet pipe for outputting fluid at its second end,

rollers (4) rotatable about the longitudinal axis of said container (3) and placed at said first and second ends of container (3),

a body (2) having a first end and a second end, back and side walls, as well as an internal cavity for accommodating said container,

mutually parallel guide plates (1) provided with shaped grooves installed near said first and second ends of said body (2),

in which the said shaped grooves and rollers (4) are made in such a shape that they ensure the fixation of the container (3) from movement along its longitudinal axis and the prevention of spontaneous separation of the said first and second ends of the container (3) from the guide plates (1).

As shown in FIG. 2 said groove has a helical shape.

The device functions as follows.

The container (3) is aligned with the rollers (4) with the spiral grooves of the support guides (1). To facilitate installation at the inlet of the spiral groove, roller catchers in the form of a lead-in cone (Fig. 4) can be provided to compensate for the inaccuracy of the support rollers entering the grooves. The spiral grooves are designed in such a way that the connecting fittings of the shut-off angle valves lead towards the operator and at the end have roller catchers that center the sampling device at the sampling point. This design ensures that the container (3) is securely held in the grooves during system operation, and also protects the operator in case of an emergency (for example, depressurization of the connecting fittings). The deviation of the support guides (1) from the horizontal axis makes it easier to pass through the spiral grooves.

The location of the tank handle (3) relative to the quick coupling fittings allows the operator to position the tank (3) in the direction of the quick coupling bodies attached to the hoseless connection device and set the most advantageous position.

Thus, unlike known devices, in which the sampling container is fixed with clamping devices, the installation of the sampling container (3) in this device is carried out with one hand, because it is not required to clamp or fix fastenings in devices with the second hand. The second hand can support the cylinder if the weight of the cylinder is large, thereby insuring the operator from falling of the cylinder.

During the operation of the device, there is no cyclic mechanical action of the clamping devices on the walls of the sampling vessel operating under excessive pressure. This increases the passive safety of the system operation.
