Description

The invention relates to chemical engineering, in particular, to the design of devices for filling cylinders with compressed gas and can be used at gas-distributing stations and gas-filling stations. For example, clamps for filling cylinders, including two handles, fixed and movable with an eccentric, clamping head and two springs, one of which is used to manually adjust the clearance through the thickness of the valve, and the second to open the gas flow after switching off the cylinder from the gas manifold 11. The disadvantages of the described clamps include the inconvenience of work (the cylinders must be clamped in a suspended state, this worker spends large physical EFFECTS for diluting the clamp handle with two hands open mouth to cover the locking device), rapid wear of the clips due to the impossibility of quick and correct adjustment of the shed across the thickness of the locking device and the ability to connect only ballons with the locking device of the angular valve type. Another type of known devices for filling cylinders with liquefied ra-i includes a housing in which a clamping head with a valve, an eccentric with a handle and a movable chamber with a saddle and a pusher are located, on the outer surface of which a movable spring-loaded sleeve with an o-ring 2 is seated. Such devices they also have a number of significant drawbacks, namely: the work on filling the walls is done manually, which leads to low productivity of labor; Such devices allow only cylinders with a shut-off device such as a non-return valve to be connected to the manifold, which limits its functionality / unsatisfactory safety conditions, since, putting such a device on the balloon, the worker is above the balloon and some of the gas released into the atmosphere at the moment of shut-off devices on the cylinder and. at the time of removing the device from the cylinder, gets into the face of the worker. The closest in design to the present invention is a device for filling cylinders with liquefied gas, containing a cylindrical body with

a fitting for supplying the working medium and a stop bracket, made in the form of two racks, one ends of which are fixed in the housing and the other are connected by a cross member. The valve body with a button, a piston and a hollow rod mounted in the piston are located in the device housing. Said rod is connected to a nozzle for supplying liquefied gas and is provided with a clamping head 3.

The performance of such a device is pneumatic compared to. using manual devices of similar purpose to increase labor productivity, reduce technological losses of liquefied gas, and improve production culture.

However, such a device makes it possible to connect only cylinders with a shut-off device such as an angular pinpoint valve to the filling manifold, which limits its functionality.

The purpose of the invention is to expand the functionality of the device.

The goal is achieved by the fact that the device is additionally equipped with a pusher fixed on the rod opposite the clamping head, and the cross-member of the stop bracket is made in the form of a plate with a semicircular cutout.

In this case, the plunger can be made removable.

Figure 1 shows the proposed device, a longitudinal section; on. figure 2 - view And figure 1.

A device for filling a cylinder with liquefied gas contains a cylindrical body 1, divided into two cylinders 2 and 3, interconnected by an opening 4. In cylinder 2 there is a valve switch with button 5, including a double-sided valve b with sealing gaskets 7 and button 8, which associated with the rod 9, on which a cylindrical spring 10 is mounted. In the cylinder 3 there is a piston 11 into which a hollow rod 12 is screwed with a cylindrical spring 13 mounted on it. Inside the rod 12 there is a spring 14. In the rod 12 there is a screw head 15 screwed in to Torah disposed rod 16 associated with valve 17 having a sealing gasket 18. On the rod 16 is secured removable on the plunger 19. A rod 12 is secured ° fitting for supplying the liquefied gas 20.

A fitting for supplying the working medium 21 (air or gas vapor medium) is located at one end of the housing 1, and a stop bracket 22 is included at the second end and includes two columns 23, one ends of which are fixed to the end of the housing 1, and the others are connected by a plate 24 one side of which has

a semicircular notch 25, and a stiffening rib 26 is welded to the second side, on which a bar 27 is fixed. The plate 24 is mounted perpendicular to the longitudinal axis of the housing 1,

The device works as follows.

In the initial position, the valve 6 is open and the working medium (air or vapor phase of liquefied gas through the nozzle 21 and the opening 4 enters the cylinder 3. In this case, the piston 11 with the rod 12 is shifted to the extreme right position.

To connect the device to the shut-off device of the cylinder (not shown), press the button 8, as a result of which the valve 6 moves to the lower position, blocks the air inlet through the nozzle 21 and closes the opening 4. After the air enters the cylinder 3, the piston 11 with the rod 12 retracts to the left , giving the opportunity to make the docking of the locking device of the cylinder (not shown).

When filling cylinders with shut-off devices such as an angle valve (WB-1, WB-2, WBK-6-16, etc.), the inlet nipple-c valve (not shown) is put on the clamping head 15, and the bar 27, for better coordination of the position the device in relation to the valve is fixed on the plate 24, closing the semicircular notch 25.

When filling cylinders with a locking device such as a reverse valve (KB-1, KB-3, etc.), the plate 24 with a semicircular notch 25 is inserted into an annular groove located on the body of the locking device (not shown). At the same time, the strip 27 is again fixed on the stiffening rib 26 in order to maintain a constant weight of the device. Then the button 8 is released, the valve 6 opens and the air begins to flow into the cylinder 3. The piston 11 with the rod 12 moves to the right and the clamping head 15 is pressed tightly against the stop valve. The pusher 19, having touched the fitting of the locking device (such as a check valve), is buried by opening the valve 17, through which gas enters the cylinder ,.

After filling the cylinder, press the button 8 again, stopping the supply of working medium to the cylinder 3. The piston 11 with the rod 12 under the action of the spring 13 moves to the left, allowing you to disconnect the device from the locking device of the cylinder and shut off the gas supply,

In the case of filling large-capacity cylinders to accelerate their filling, the pusher 19 is unscrewed from the rod 12, thus increasing the opening for the passage of gas.
