Description

HA CALL reducer

The inventive utility model relates to the field of construction, specifically, to devices for regulating daElenyl gas.

The gas reducer is known / the book Reducer of gas pressure, author A.I. 3del ./; en, 113-th Engineering, M D981g, pp. 117-116, es.6.14 /, in KOTopoE / i the problem of stability of the reducer is solved due to the introduction of friction in the gearbox. To do this, the pushers are made of different lengths, iio3Toi / iy shutter and support ivieiv: dpaHK work with nepeKOCOivi, Friction on the walls of the gearbox of the support causes damping of the oscillating system.

The disadvantage of this design is the instability of the output pressure.

There is also a well-known gas (see book) Gas pressure reducers, author A.I. Zdelyu an, IE-BO Mechanical Engineering, M., pp. 39-40, fig.ZN1Sh 3.19 and 3.20 /. The operation of this gearbox can be traced to 3.19, where the fastening gage Separating 1u faders equals shutter saddles. The areas of the separation membrane 7 and the seat 4 are equal, the force that acted on the movable system after the gas was supplied does not change and the position of the shutter 6 does not change. When loading the spring with the adjusting screw b; select 3 lifts the shutter 6, overcoming the force 8. The gas passes through the gap with the saddle and shutter, B low pressure cavity enters. According to the khanal, gas from the low-pressure cavity passes p equalizing. The force from the pressure B of the low-pressure cavity is transmitted through the L5e1brane 3, balancing the force of the prulsion 2.

 2 If there is no gas flow, then the pressure E of the low-pressure cavity increases, Keiv dpaHa bends to the E side of B 2 and, under action 1, go: NEXT. The shutter 6 will seat on the saddle 4.

OcHOEHEivi the disadvantage of the indicated design of the gas reducer is the slushy construction, which entails the difficulty of manufacturing and increasing the dimensions.

This design of the gas gear is taken as a prototype.

 The box has a different technical solution aimed at maintaining a constant outlet pressure of the gas stream, reducing the dimensions of the redirector, simplifying the design,

The task is solved due to the fact that the main gearbox contains a housing, a tuning part, consisting of pushers, a membrane, a tuning screw and a tuning rod; strings, a reducing valve, including a housing, a seal and a piston,

A distinctive feature is that in the seal of the reducing valve there is a balancing chamber bounded by a piston, and the diameter of the balancing kaker is equal to the diameter of the seat.

An analysis of the totality of the essential features of the proposed solution, ensuring its difference from the known solutions, indicates the compliance of this decision with the Eovizna criterion.

The pertinence of making a statement is useful: if a product is to be sold in AOZT, it indicates that its criterion is industrial applicability.

The essence of the claim is useful, which is explained below, where (1IG.1 shows a gas reducer in section.

Prunin 2, HyvmbranE 3, Pusher 4 and 5.

The reducing valve consists of a housing 6, a seal 7, a piston 8 with an o-ring 9. Into the seal:,. ,, 7 BKPOLken uraEnovesh aE, ayuayday camera 10, B casing redZaktora II ikayut supply 12 and Bkhodnoy 13 channel. JUH is interconnected with a pressure reducing valve body II is equipped with a seat 14. The pressure reducing valve is CONNECTED to the seat 14 of the team 15. Channel 12 is connected to a fixed chamber 10, a working pressure cavity 16 channels 17.

The gas reducer works as follows: gas enters from the gas cylinder through the drip 12 E, the riveted space to the seat 14.., When the desired gas pressure is received at the outlet / B E Exit channel 13 /, rotate the adjusting BAND I. Load through spring 2, ivieividpaHy 3 and pushers 4 and 5 is transmitted to the reducing valve. Open the valve:. It turns out and the gas enters the working pressure cavity 16. When the pressure is rotated in the working pressure cavity 16, the gas acts on iv: er./iran 3, which, in turn, from the hub 2, to balance the forces from pressure gas and action pruzshnk 2.

lipE changes in pressure (according to the gas flow rate), the force exerted on the valve by the action of pressure; the gas cylinder decreases. To obtain raBN01; black pressure in the input. channel 13, gas flows from channel 12 through channel 17 to balancing kakeru 10,

which leads to balancing the forces acting on the valve. And since the saddles of 14 Shaure 10 are equal, then the forces

acting on the valve are balanced.
