Abstract

The utility model relates to the field of mechanical engineering, namely to the valve industry, specifically to the marking of pipeline valves. The technical task of the utility model is to improve consumer properties. The technical problem is solved by the fact that a ball valve containing a body with two channels, in a horizontal passage channel, is installed coaxially with inlet and outlet with sealing elements, fittings, between which a ball plug is placed, controlled by a spindle located in the vertical channel of the body, while the collar of the largest diameter of the spindle is located in the counterbore of the passage channel of the body, and its smooth cylindrical part is hermetically sealed relative to the body, and the control handle with its limited rotation is fixed on the square part, while the control handle is fixed with a lock in the form of a bracket, the lower shelf of which is made in the form of a fork, from two sides interacting with the grooves of the square part of the spindle, and the upper shelf is made solid and flat and closes the upper surface of the control handle, and the lock is sealed through the holes in both of its shelves, and the upper shelf of the lock can be made with larger dimensions than the lower one.

Description

The utility model relates to the field of mechanical engineering, namely to the valve industry, specifically to the marking of pipeline valves.

All pipeline fittings must be supplied to the customer with marking in accordance with the requirements of GOST 4666-2015. The requirements for labeling provide quantitative and dimensional characteristics. Only on the side of the "mandatory" signs it is necessary to put nine parameters, and on the side of the additional - twenty-two parameters.

For pipeline fittings for the AU, oil and gas industry, additional markings are required.

For pipeline fittings with a nominal diameter of DN<50, it is allowed to put the necessary signs on a tag or plate, while fastening the tag (plate) at the discretion of the manufacturer. At the same time, the largest number of pipeline fittings falls on ball fittings, with DN<50, with manual control by the handle.

A ball valve is known (see RU 3020 U1 F16K 3/06), containing a body with two channels, fittings are installed horizontally coaxially on both sides in the inlet and outlet pipes, interacting through sealing elements with a ball plug driven by a spindle sealed relative to the vertical body channel. A control handle is mounted on the square top of the spindle, fixed with a nut and washer.

The disadvantages of this design include low consumer properties, due to the fact that:

1. To replace the seal that seals the spindle, it is necessary to remove the ball valve from the pipeline.

2. Due to the insufficient area of the outer surface of the housing, an additional tag is required to apply all the necessary signs in accordance with GOST 4666-2015. Over time, the tag may be lost.

A ball valve is also known (see RU 213918 U1, F16K 5/06) a prototype containing a body with two channels, in a horizontal coaxial on both sides in the inlet and outlet pipes, nozzles are installed through sealing elements that interact with a ball plug controlled by a spindle, sealed relative to the vertical channel of the body, its large diameter part is located in the counterboring made in the horizontal channel, on its upper part there is a control handle fixed with a washer and nut.

The disadvantages of this design also include:

1. Insufficient reliability of the connection of the control handle with the spindle (only due to the friction forces arising from the action of the nut), since the vibration inherent in the operation of pipelines can significantly reduce the clamping force, and the valve may become uncontrollable.

2. Due to the insufficient dimensions of the body, all or part of the markings will be applied to the tag, somehow fixed to the ball valve, which does not exclude its loss. That is, low consumer properties.

The technical task of the utility model being solved is to increase consumer properties. The technical problem is solved by the fact that a ball valve containing a body with two channels is installed coaxially inlet and outlet with sealing elements in a horizontal passage channel, fittings, between which a ball plug is placed, controlled by a spindle located in the vertical channel of the body, on the square part of the spindle the control handle is fixed with its limited rotation, while the control handle is fixed with a lock in the form of a bracket, the lower shelf of which is made in the form of a fork, interacting on both sides with the grooves of the square part of the spindle, and the upper shelf is made solid and flat and closes the upper surface of the control handle, and the lock is made with the possibility of sealing through the holes in both of its shelves, and the upper shelf of the lock can be made with larger dimensions than the lower one.

In FIG. 1 shows a longitudinal section of a ball valve in the "open" position;

in fig. 2 lock in Fig. 1 isometric.

The ball valve consists of a body 1, an inlet fitting 2 and an outlet fitting 3 are installed coaxially at both ends of the body, interacting through sealing elements 4 with a ball plug 5 controlled by a handle 6 through a spindle 7 having a collar 8 through a sealing gasket 9, based on a bore 10 of the housing 1. The smooth part of the spindle 7 is sealed relative to the vertical channel of the housing 1 by the element 11, which is pressed by the nut 12. On the square part 13 of the spindle 7, a handle 6 is installed, which interacts with the limiter 14 when turning. The handle 6 is fixed on the spindle 7 with a lock 15, the lower shelf of which on both sides it is placed in grooves 16, and the upper shelf closes the square hole in the handle 6. Both shelves are mutually sealed with seal 17.

Ball valve assembly

A spindle 7 with a sealing gasket 9 is inserted into the through horizontal channel of the body 1 and placed in the vertical channel of the body 1 so that the spindle element 7 is connected to the ball plug 5, located along the longitudinal axis of the body 1. After that, a ball valve is inserted into the through channel of the body 1. plug 5 (in the “closed” position), connecting it with the spindle 7. Then, fittings 2 and 3 with sealing elements 4 are screwed (baited) on both sides of the body 1. And a sealing seal 11 is installed on the spindle 7 and pressed with a nut 12.

Handle 6 makes a trial turn with ball plug 5, fittings 2 and 3 are mounted. After that, handle 6, limiter 14 and lock 15 are installed and sealed with seal 17.

The ball valve is ready for operation.

Thus, due to the fact that fastening the control handle of a removable lock with subsequent sealing allows marking marks on the upper solid shelf of the lock in accordance with GOST 4666-2015 that did not fit on the side surfaces of the ball valve body. And the sealing of the lock does not allow unauthorized removal of the control handle, but at the same time it secures the lock.

Together, this, of course, increases the consumer ability of the ball valve.

Claims (2)
