Description

The utility model relates to gas flow controllers and can be used in gas flow control systems. Known flow rate controller containing a housing, the first and second throttling zones located in the housing,

a hydraulic actuator, which is equipped with a membrane, one side of which forms the wall of the first pressure chamber in communication with

intake chamber of the flow regulator. The other side of the membrane forms the wall of the second pressure chamber. The membrane is connected by a rod with an adjusting cone. The second throttling zone has a cone, which is mounted with the possibility of stepless axial movement relative to the hole by means of a valve actuator through the valve axis. The cone of the second throttling zone contains at least two separate parts, which are mounted to move one relative to the other. The regulator allows you to make the flow through the regulator independent of the differential pressure while maintaining the entire adjustment range (patent. No. 2161815. IPC G 07 D 7/00).

it does not allow for fine adjustment of gas.

A device for regulating the flow of gas which contains a fitting with nipples for supplying and outputting gas, a regulating body installed inside the fitting with the possibility of reciprocating movement and rotation (patent No. 2141127. IPC G 07 D 7/00) is a prototype.

The disadvantage of this design is that it does not allow for fine adjustment of the gas.

The technical task of the claimed utility model is the provision of fine adjustment of gas flow.

The technical problem is achieved by the fact that the known design contains a fitting with nipples for supplying and discharging gas, a regulating body mounted inside the nozzle with the possibility of reciprocating movement, and the regulating body is made in the form of a needle with a sleeve, one end of the needle is fixed in a bearing, which is rigidly installed in the case, with the ability to move relative to the fitting, and the surface of the second end of the needle and the inner surface of the sleeve have sections of the same shape. To achieve an additional effect associated with the reliability and durability of the device, the sleeve is made of plastic material.

 lOf (

Comparison of the claimed utility model with the prototype shows that it differs in the following features:

-regulating body is made in the form of a needle with a sleeve;

- one end of the needle is fixed in a nipper;

-the bearing is rigidly mounted in the housing, having the ability to move relative to the fitting;

- the surface of the second end of the needle and the inner surface of the sleeve have sections of the same shape;

- The sleeve is made of plastic material. Therefore, the claimed utility model meets

the criterion of “novelty.

The utility model can be manufactured on standard equipment using well-known technological methods, therefore it meets the criterion of “industrial applicability.

The figure shows the claimed utility model.

The device comprises a fitting 1, in which a regulatory body is located in the form of a needle 2, one end of which is fixed in the bearing 3, which is rigidly fixed in the housing 4, which, in turn, has the ability to move relative to the fitting 1. The second end of the needle is located inside the sleeve 5.

The device includes a nipple 6 for supplying gas and a nipple for venting gas.

The device operates as follows.

Gas is supplied through the nipple 6 to the sleeve 5. To adjust the gas flow rate, the housing 4 is rotated, which moves relative to the nozzle 1. Since the needle 2 is rigidly fixed in the bearing 3, the housing 5, it also translates between the inner surface of the sleeve 3 and the surface of the needle 2 forms the required gap through which gas passes, which is subsequently discharged through

X / -t.
