Abstract

The utility model relates to a reversing valve, which comprises a valve body, wherein the valve body is provided with a working cavity and an oil return way; and an overflow valve mounting hole is also formed in the valve body and is communicated with the working cavity and the oil return way. According to the reversing valve, after the overflow valve mounting hole is formed in the valve body, an overflow valve can be arranged on the valve body during use, so that an auxiliary oil tube and an auxiliary valve can be eliminated, the using cost of the reversing valve can be reduced, the mounting space of the overflow valve is also reduced substantially when a check valve is used, and the influence on the layout of a complete machine with the reversing valve is small.

Description

Selector valve

Technical field

The utility model relates to a kind of selector valve.

Background technique

Existing selector valve in use; Work safety for the protection oil circuit need be provided with a relief valve oil circuit is carried out overload protection, but not have suitable mounting point on the existing selector valve; Relief valve can only be installed on the oil pipe of peripheral hardware; Need set up auxiliary oil pipe and other auxiliary valve, auxiliary oil pipe and auxiliary valve not only can increase the user cost of selector valve, and can the layout of the complete machine of one-way valve work be impacted.

Summary of the invention

For solving above-mentioned technical problem, the utility model provides a kind of reduces user cost, can reduce the selector valve to the influence of complete machine layout.

The technological scheme of the utility model is; A kind of selector valve with following structure is provided, and it comprises valve body, and described valve body is provided with active chamber and oil return circuit; Also be provided with the relief valve mounting hole on the described valve body, described relief valve mounting hole all is communicated with active chamber and oil circuit.

After adopting said structure, the utlity model has following advantage:

On valve body, be provided with after the relief valve mounting hole, in use, relief valve just can between be installed on the valve body; So just can omit auxiliary oil pipe and auxiliary valve; Not only can reduce the user cost of selector valve, and, at one-way valve in use; The installing space of relief valve also significantly lowers, and is also just less to the layout influence of complete machine that selector valve has been installed.

Description of drawings:

Fig. 1 is the structural representation of the utility model selector valve;

Embodiment:

Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.

As shown in Figure 1, the utility model selector valve, it comprises valve body 1, and described valve body 1 is provided with active chamber 2 and oil return circuit 3, also is provided with relief valve mounting hole 4 on the described valve body 1, and described relief valve mounting hole 4 all is communicated with active chamber and oil circuit.Because the active chamber 2 on the general valve body 1 all has two, and is positioned at the both sides of valve body 1, therefore, relief valve mounting hole 4 also is provided with two, lays respectively on the valve body 1 and two active chambers, 2 corresponding both sides.

Claims (1)

1. selector valve; It comprises valve body (1); Described valve body (1) is provided with active chamber (2) and oil return circuit (3), it is characterized in that: also be provided with relief valve mounting hole (4) on the described valve body (1), described relief valve mounting hole (4) all is communicated with active chamber and oil circuit.
