Abstract
The invention discloses a semiautomatic hand-operated reversing valve. The reversing valve comprises a valve body, a valve core, a handle and a spring, wherein the valve core is arranged inside the valve body; the spring is installed at one end of the valve core; the handle is arranged at the other end of the valve core; and the spring is located between the valve core and the valve body. According to the semiautomatic hand-operated reversing valve, the flow direction can be switched conveniently and fast through the handle, and in addition, the valve core can be restored automatically without the control of the handle, so that the effect that the reversing valve stays in a closed state is guaranteed.
Description
Technical field
The present invention relates to reversal valve field, be specifically related to a kind of automanual hand-operated direction valve.
Background technology
Reversal valve is the directional control valve with two or more liquid form and two or more hydraulic fluid port, is realize the communication of hydraulic oil flow, cut-out and commutation, and the valve that discharge degree and sequentially-operating control.Hydraulic control system is often used hand-operated direction valve, for the flow direction of manual control hydraulic oil.But existing hand-operated direction valve structure is single, it is impossible to solve some common problems while using hand-operated direction valve.
Summary of the invention
(1) to solve the technical problem that
For the deficiency that prior art exists, the present invention provides a kind of automanual hand-operated direction valve.
(2) technical scheme
For reaching above-mentioned purpose, the invention provides a kind of automanual hand-operated direction valve, including valve body, spool, handle and spring, described spool is arranged in described valve body, described spring is arranged on one end of described spool, described handle is arranged on the other end of described spool, and described spring is between described spool and described valve body.
Further, it is rotatably connected between described handle with described valve body, one end of described spool is provided with installation projection, described handle is provided with mounting groove, described installation projection is arranged in described mounting groove, one end of described handle is provided with rotating hole, and described handle is arranged on described valve body by described rotating hole.
(3) beneficial effect
The automanual hand-operated direction valve of the present invention can pass through handle changing flow direction easily and fast, and this is external not by the control bottom spool energy automatic homing of handle, it is ensured that reversal valve is in closure state.
Accompanying drawing explanation
Fig. 1 is the automanual hand-operated direction valve structure schematic diagram of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following example are used for illustrating the present invention, but are not limited to the scope of the present invention.
The structure of a kind of automanual hand-operated direction valve of the present invention is as shown in Figure 1, including valve body 2, spool 1, handle 3 and spring 7, described spool 1 is arranged in described valve body 2, described spring 7 is arranged on one end of described spool 1, described handle 3 is arranged on the other end of described spool 1, and described spring 7 is between described spool 1 and described valve body 2.
Wherein, it is rotatably connected between described handle 3 with described valve body 2, one end of described spool 1 is provided with installation projection 4, described handle 3 is provided with mounting groove 5, described installation projection 4 is arranged in described mounting groove 5, one end of described handle 3 is provided with rotating hole 6, and described handle 3 is arranged on described valve body 2 by described rotating hole 6.
Beneficial effects of the present invention: can pass through handle changing flow direction easily and fast, this is external not by the control bottom spool energy automatic homing of handle, it is ensured that reversal valve is in closure state.
The above is only the preferred embodiment of the present invention; it should be pointed out that, for those skilled in the art, under the premise without departing from the technology of the present invention principle; can also making some improvements and modifications, these improvements and modifications also should be regarded as protection scope of the present invention.
