Abstract
A mechanical flow valve comprises a flow adjusting valve and further comprises a two-position two-way reversing valve and a one-way valve. The two-position two-way reversing valve, the one-way valve and the flow adjusting valve are connected in parallel. When the two-position two-way valve is off, the flow of a system oil path is mainly controlled, the flow is made to be constant basically and is not influenced by pressure and temperature, and the flow is controlled through an adjusting knob. When the two-position two-way valve is on, a speed adjusting valve is in a short circuit, oil directly passes through the reversing valve, and therefore quick cocurrent flow is achieved, and a quick returning action can be done. When the oil is fed reversely, the oil is fed through the one-way valve directly, and therefore the speed adjusting valve is also in a short circuit. Therefore, the multistage speed adjusting feeding and quick returning function of the valve can be achieved in a hydraulic system, and the mechanical flow valve is widely applied to hydraulic systems of machine tool equipment. When the quick returning action is needed, the maximum flow can be achieved simply by directly opening the two-position two-way valve, and the response of the system is greatly accelerated.
Description
Technical field
The utility model belongs to hydrovalve technical field, especially designs a kind of mechanical flow valve applying in machine tool hydraulic equipment.
Background technique
In the hydraulic circuit of some lathes, require the speed of oil cylinder can regulate control, this generally just can be realized by a series flow control valve, and series flow control valve generally rotates control by people.The speed of oil cylinder can only be rotated progressively and be regulated by series flow control valve, but for some occasions, while returning fast as needs, at this moment it is maximum that the flow that needs speed governing to regulate reaches rapidly, if originally series flow control valve is also adjusted in the position that flow is less, the position that turns to flow maximum needs the regular hour, and this has reduced the response efficiency of system undoubtedly.
Summary of the invention
The utility model, for the deficiencies in the prior art, provides a kind of mechanical flow valve, has greatly improved the response efficiency of system when returning fast.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals: mechanical flow valve, comprise flow-adjustable valve, also comprise a bi-bit bi-pass selector valve, an one-way valve, described bi-bit bi-pass selector valve, described one-way valve and described flow-adjustable valve are parallel with one another.When bi-bit bi-pass selector valve is obstructed, it is mainly the flow of control system oil circuit, makes it substantial constant, is not stressed and the impact of temperature, controls the size of flow by adjusting knob; When bi-bit bi-pass selector valve is connected, series flow control valve is by short circuit, and fluid directly passes through from selector valve, thereby realizes quick cocurrent flow, at this moment can return fast action; During reverse oil-feed, fluid is directly by one-way valve oil-feed, and same series flow control valve is by short circuit; Therefore, this valve can be realized multistep speed regulation feeding and quick retraction in hydraulic system, is widely used in each machine tool hydraulic system.When needs are return action fast, as long as directly two position two-way valve is connected, just can realize flow maximum, the response of system is accelerated greatly.
In technique scheme, preferred, also comprise a reduction valve, described reduction valve in parallel with described one-way valve.The effect of reduction valve is that a high pressure is reduced to needed convenient pressure, and other elements after protection reduction valve valve are not destroyed by high pressure, guarantee the stable of outlet pressure simultaneously.
The utility model compared with prior art, has following beneficial effect: when needs are return action fast, as long as directly two position two-way valve is connected, just can realize flow maximum, the response of system is accelerated greatly.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment's schematic diagram.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
Referring to Fig. 1, mechanical flow valve, comprises a flow-adjustable valve 1, bi-bit bi-pass selector valve 2, one-way valve 3 and a reduction valve 4, and described bi-bit bi-pass selector valve 2, described one-way valve 3, described reduction valve 4 and described flow-adjustable valve 1 are parallel with one another.
When bi-bit bi-pass selector valve is obstructed, it is mainly the flow of control system oil circuit, makes it substantial constant, is not stressed and the impact of temperature, controls the size of flow by adjusting knob; When bi-bit bi-pass selector valve is connected, series flow control valve is by short circuit, and fluid directly passes through from selector valve, thereby realizes quick cocurrent flow, at this moment can return fast action; During reverse oil-feed, fluid is directly by one-way valve oil-feed, and same series flow control valve is by short circuit; Therefore, this valve can be realized multistep speed regulation feeding and quick retraction in hydraulic system, is widely used in each machine tool hydraulic system.When needs are return action fast, as long as directly two position two-way valve is connected, just can realize flow maximum, the response of system is accelerated greatly.
