RU46975U1 - VALVE ASSEMBLY FOR PUMPING TIRES - Google Patents

Abstract

The valve assembly for inflating tires can be used in the manufacture of pneumatic chambers and constant pressure tires for tractors, tractor trailers and road machines. And also the valve assembly for inflating tires can be used as a repair. The purpose of the utility model is to reduce labor costs in the manufacture of constant pressure tire tubes for tractors, tractor trailers and road equipment in tire factories, to increase the reliability, maintainability and service life of the valve (assembly). The essence of the utility model in the manufacture and installation of the cuff at the valve manufacturer. The cuff is not vulcanized to the sleeve, which allows replacement of the cuff in any conditions, its delivery to the part hall. The valve assembly for inflation of tires assembled from the valve manufacturer is supplied to tire factories and mounted in a housing vulcanized to the chamber, which reduces the labor required for rubberizing the sleeve at tire factories and increases the maintainability of the chamber for consumers.

Description

1. The technical field to which the utility model relates.

The valve assembly for inflation of tires relates to mechanical engineering, mainly for chamber tires of tractors.

2. The level of technology

The well-known valve TK GOST 8107-75 is a valve for pneumatic chambers and constant-pressure tires, the main elements of which are the body, casing, sleeve, spool, key cap, nipple. The disadvantages of the valve TC GOST 8107-75 are:

The cuff is attached to the valve sleeve in tire plants using vulcanization methods, so the valve is limited to maintainability. Repairing it (replacing the sealing sleeve) is possible only under production conditions, requires special equipment and a significant investment of time.

3. Disclosure of utility model

The essence of the utility model as a technical solution is expressed in the fact that it becomes possible to produce the cuff at the valve manufacturer's factory separately from the sleeve. Assemble the sleeve with a sleeve, spool, nipple and check the assembly for leaks, which will significantly reduce labor costs for vulcanization, assembly and leak tightness of the valve sleeve in tire plants. The cuff is not vulcanized to the sleeve and therefore can be quickly replaced in any conditions, which increases the maintainability and service life of the valve.

1. - valve body TC

2. - assembly-sleeve valve TC assembly

3. - TC valve cover

Figure 2 (Figure 2) - the proposed design of the valve assembly TK assembly for delivery to tire plants instead of commercially available

1. - cap key V 8 GOST 8107-75;

2. - sleeve in the assembly of the valve TC;

3. - spool V 8 GOST 8107-75

4. - cuff (removable)

5. Implementation of a utility model

The tire inflation valve consists (FIG. 1) of:

1. - valve body TC

2. - valve cover TC

3. - assembly-sleeve valve TC assembly

In turn, the node consists (figure 2) of:

1. - cap key V 8 GOST 8107-75;

2. - TK valve sleeve;

3. - spool V 8 GOST 8107-75;

4. - valve nipple TK;

5. - cuff (removable)

The assembly of the TC valve assembly is supplied to tire plants and installed directly into the housing vulcanized to the chamber, excluding cuff vulcanization, and assembly of the assembly, which significantly reduces labor costs at tire plants. During operation of the valve, if necessary, it is possible to replace the cuff with a new one in any conditions.

The valve assembly assembly TC fully complies with the technical requirements of GOST 8107 and is interchangeable with commercially available products.

Claims (1)

Valve assembly for inflating tires, including a slide valve, key cap, nipple, body sleeve, seal, characterized in that a removable sleeve is installed on the valve sleeve.
