All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention. Unless defined otherwise, technical or scientific terms used herein shall have the ordinary meaning as understood by one of ordinary skill in the art to which this invention belongs. As used herein, the word "comprising" and similar words are intended to mean that the element or item preceding the word comprises the element or item listed after the word and its equivalent, but not the exclusion of other elements or items.
Aiming at the problems in the prior art, the embodiment of the utility model provides a valve group special for motor overload protection.
Examples
As shown in fig. 1 to 3, a valve set special for motor overload protection comprises a rectangular valve body 1; a first pressure overload valve 2 and a second pressure overload valve 3 are mounted at the top of the valve body 1; the first pressure overload valve 2 and the second pressure overload valve 3 both comprise an oil inlet 4 and an oil outlet 5; a first oil source interface 6, a second oil source interface 7 and an oil return port 8 are arranged on the front side surface of the valve body 1; a first motor interface 9 and a second motor interface 10 are arranged on the rear side surface of the valve body 1;
the first oil source interface 6 and the second oil source interface 7 are connected with an oil source; the first motor interface 9 and the second motor interface 10 are connected with a motor; the first oil source interface 6 is connected with a first motor interface 9; the second oil source interface 7 is connected with a second motor interface 10; the first oil source connector 6 and the first motor connector 9 are connected with an oil inlet 4 of the first pressure overload valve 2; an oil outlet 5 of the first pressure overload valve 2 is connected with an oil return port 8; the second oil source connector 7 and the second motor connector 10 are connected with an oil inlet 4 of the second pressure overload valve 3; an oil outlet 5 of the second pressure overload valve 3 is connected with an oil return port 8; the oil return port 8 is connected with an oil tank.
A through hole 11 for installation is provided between the front side and the rear side of the valve body 1.
The first pressure overload valve 2 and the second pressure overload valve 3 are plug-in valves.
The valve body 1 is made of alloy steel.

The first motor connector 9 and the second motor connector 10 are connected with a motor through rubber pipes.
The oil return port 8 is connected with an oil tank through a rubber pipe.
The working principle of the utility model is as follows:
when the motor rotates forwards: hydraulic oil in the oil source flows into the motor cavity from the first oil source interface 6 to the first motor interface 9, flows out from the other cavity of the motor to the second motor interface 10 and then returns through the second oil source interface 7, so that the motor can rotate forwards, when the motor is influenced by load change or other factors in the operation process, and pressure suddenly rises, the first pressure overload valve and the second pressure overload valve can timely and effectively unload the pressure, and the motor is protected from being damaged.
When the motor is reversed: hydraulic oil in the oil source flows into the motor cavity from the second oil source interface 7 to the second motor interface 10 and flows out of the other cavity of the motor to the first motor interface 9 and then returns through the first oil source interface 6, so that the motor is reversed.
Although the embodiments of the present invention have been described in detail hereinabove, it is apparent to those skilled in the art that various modifications and variations can be made to these embodiments. However, it is to be understood that such modifications and variations are within the scope and spirit of the present invention as set forth in the following claims.
