Disclosure of Invention

The utility model solves the problems that a two-position five-way mechanical valve control mechanism is easy to damage and difficult to replace in the prior art, and provides the two-position five-way mechanical valve control mechanism which can solve the problems.

In order to solve the technical problems, the utility model adopts the following technical scheme:

a two-position five-way mechanical valve control mechanism comprises a bearing, a compression bar and a fixing piece;

the compression bar is provided with a mounting groove, mounting holes are formed in two sides of the mounting groove, the bearing is mounted in the mounting groove, and the bearing is mounted through a fixing piece.

The original roller is replaced by the bearing, friction between the bearing and the contact surface can be reduced, the bearing is installed in the installation groove through the fixing piece, the bearing can be replaced through the mode of disassembling the fixing piece, the replaceability of the control mechanism is greatly improved, and the service life of the two-position five-way mechanical valve is prolonged.

The further technical scheme is that the bearing is a deep groove ball bearing.

The further technical scheme is that the two-position five-way mechanical valve control mechanism further comprises a gasket, and the gasket is arranged between the bearing and the compression bar.

Through installing the spacer additional, can make the bearing outer lane rotate in a flexible way to can reduce the clearance between bearing and the depression bar, make the bearing rotate more stably.

The further technical proposal is that the sum of the widths of the gasket and the bearing is 0.1-1 mm smaller than the width of the mounting groove.

The further technical proposal is that the fixing piece comprises a screw and a nut;

the screw passes through the mounting hole and the bearing, and the nut is mounted on the screw.

According to a further technical scheme, two bearings are arranged, the two bearings are overlapped together, and the two bearings are installed in the installation groove through the fixing piece.

By using two bearings to be installed in the installation groove, the contact area between the bearings and the contact surface can be increased, the pressure born by a single bearing is reduced, and the bearing damage is avoided.

Compared with the prior art, the utility model has at least the following beneficial effects: according to the utility model, the bearing is arranged in the mounting groove of the compression bar of the two-position five-way mechanical valve control mechanism by using the fixing piece, so that the existing cast iron roller is replaced, the two-position five-way mechanical valve control mechanism is more durable, meanwhile, as the fixing piece is detachable, after the bearing is damaged, the bearing is only required to be replaced, and the waste caused by scrapping of the two-position five-way mechanical valve due to the damage of the cast iron roller is reduced.

Detailed Description

The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

A two-position five-way mechanical valve control mechanism comprises a bearing 1, a compression bar 2, a fixing piece 3 and a gasket 4;

the compression bar 2 is provided with a mounting groove, mounting holes are formed in two sides of the mounting groove, the bearing 1 is mounted in the mounting groove, and the bearing 1 is mounted through a fixing piece 3.

The bearings 1 are deep groove ball bearings, two bearings 1 are overlapped, and the two bearings 1 are installed in the installation groove through the fixing piece 3.

It should be noted that the fixing member 3 may be a bolt connection or a loose rivet connection, and in this embodiment, the fixing member is a screw 31 and a nut 32, and the screw 31 passes through the mounting hole and the bearing 1, and the nut 32 is mounted on the screw 31.

The gasket 4 is installed between the bearing 1 and the compression bar 2.

The sum of the widths of the spacer 4 and the bearing 1 is 0.1-1 mm smaller than the width of the mounting groove, specifically in this embodiment, the thickness of the bearing 1 is 5 mm, the thickness of the spacer 4 is 0.5 mm, so the total thickness of the spacer 4 added to the bearing 1 is 11 mm, and the width between the pressing rods is 11.4 mm.

In the use, use bearing 1 to replace original gyro wheel to contact with the contact surface, can reduce the friction of bearing and contact surface, gasket 4 has reduced the left and right slip of bearing 1 simultaneously, makes bearing 1 more durable, and two bearings contact with the contact surface also reduced bearing surface's pressure, has played the guard action to the bearing.

When the bearing 1 is damaged, the bearing 1 can be replaced only by detaching the screw 31, the nut 32 and the gasket 4, so that the replaceability of a control mechanism is greatly improved, and the service life of the two-position five-way mechanical valve is also prolonged.

Although the utility model has been described herein with reference to illustrative embodiments thereof, it should be understood that numerous other modifications and embodiments can be devised by those skilled in the art that will fall within the scope and spirit of the principles of this disclosure. More specifically, various variations and modifications may be made to the component parts and/or arrangements of the subject combination arrangement within the scope of the disclosure.
