Abstract
The utility model discloses a kind of flow divider valve, form and comprise the diverter valve mechanism that 2 tunnels are set up in parallel above, each diverter valve mechanism is connected with oil-feed P mouth, diverter valve mechanism comprises the first damping hole (2), the recuperation valve (3) that connect successively from oil-feed P mouth, the load delivery outlet of recuperation valve (3) is parallel with the shuttle valve (4) and the second damping hole (5) that connect successively, shuttle valve (4) is connected to control mouth and the test interface (1) of recuperation valve (3), and the second damping hole (5) is connected to the load delivery outlet of recuperation valve (3).The mode of the utility model employing valve post-compensation can realize the assignment of traffic of any equal portions or any ratio, low cost.
Description
Technical field
The utility model relates to a kind of flow divider valve, especially a kind of flow divider valve that adopts valve post-compensation.
Background technique
Flow divider valve mainly contains two kinds at present:
The one, adopt the mode of flow divider-combiner, this mode can only be distributed by two Nth power, i.e. one-to-two, one point four, one points eight, one points 16, this method of salary distribution exceedes behind four tunnels, designs very complicatedly, and shunting precision is very poor, price is not cheap yet.
The 2nd, adopt the method for salary distribution of dividing syncmotor, this mode assignment of traffic precision is very high, also can realize the distribution of any umber, but the principle of this shunting is the mode that adopts in-line gears motor to shunt, cost is high, and general application is beyond affordability.And this kind of mode can not be by non-equal proportion distribution, as 20%-30%-50%.
Model utility content
The purpose of this utility model is, a kind of flow divider valve is provided.The mode of the utility model employing valve post-compensation can realize the assignment of traffic of any equal portions or any ratio, low cost.
The technical solution of the utility model: flow divider valve, comprise the diverter valve mechanism that 2 tunnels are set up in parallel above, each diverter valve mechanism is connected with oil-feed P mouth, diverter valve mechanism comprises the first damping hole, the recuperation valve that connect successively from oil-feed P mouth, the load delivery outlet of recuperation valve is parallel with the shuttle valve and the second damping hole that connect successively, shuttle valve is connected to control mouth and the test interface of recuperation valve, and the second damping hole is connected to the load delivery outlet of recuperation valve.
In aforesaid flow divider valve, there are 3 tunnels, 4 roads or 5 tunnels in described diverter valve mechanism.
In aforesaid flow divider valve, the first described damping hole is adjustable restrictive valve, Proportional valve or solenoid valve.
Compared with prior art, the utility model, by adopting valve post-compensation to realize the shared principle of flow, carries out the distribution of flow, and it can substitute flow divider-combiner, and can realize any ratio or any umber, low cost.The utility model also has the following advantages:
1, compound mode is flexible, can be divided into any equal portions;
2, the assignment of traffic ratio on each road can be arbitrarily fixed, and the size of allocation proportion is by the first damping hole control, also adjustable restrictive valve of this damping hole, Proportional valve or solenoid valve etc.;
3, exceed three roads when above, price has obvious advantage;
4, while exceeding four tunnels, the small volume of valve;
5, element is simple, and lead time is short.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Being labeled as in accompanying drawing: 1-test interface, 2-the first damping hole, 3-recuperation valve, 4-shuttle valve, 5-the second damping hole.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described, but not as the foundation to the utility model restriction.
Embodiment.Flow divider valve, form as shown in Figure 1, flow divider valve, comprise the diverter valve mechanism that 2 tunnels are set up in parallel above, each diverter valve mechanism is connected with oil-feed P mouth, diverter valve mechanism comprises the first damping hole 2, the recuperation valve 3 that connect successively from oil-feed P mouth, the load delivery outlet of recuperation valve 3 (is respectively A1, A2, A3, A4 ...) be parallel with successively the shuttle valve 4 and the second damping hole 5 that connect, shuttle valve 4 is connected to control mouth and the test interface 1 (MLS) of recuperation valve 3, this test interface 1 is for pressure measurement, and the second damping hole 5 is connected to the load delivery outlet of recuperation valve 3.The pressure of described load delivery outlet takes out by the second damping hole 5, shuttle valve 4.
Reasonable, there are 3 tunnels, 4 roads or 5 tunnels in described diverter valve mechanism.
The first described damping hole 2 can be adjustable restrictive valve, Proportional valve or solenoid valve.
M shown in figure, M1, M2, M3 etc. are test port.
Working principle of the present utility model is as follows: size (or the adjustable restrictive valve of the first damping hole, the logical oily size of Proportional valve or solenoid valve) determine the ratio of Liao Zhe road flow shared total discharge, the second damping hole is done the collection of pressure signal, gets the maximum value of point current load.This pressure signal acts on the spring chamber of compensating spool, other one end pressure signal of recuperation valve spool is from the outlet of the first damping hole, each road that so just can guarantee flow divider valve equates to the pressure reduction exporting from P mouth, the size of the flow on each road is just by long-pending decision of the logical pasta of the second damping hole like this, therefore, the assignment of traffic of flow divider valve is just only by long-pending decision of logical pasta of the first damping hole, if the damping hole size on several roads is identical, flow distributes with regard to equal portions road.If varying in size of damping hole, flow is just by the aperture area distribution that is in proportion.The precision by damping hole diameter of the precision of assignment of traffic determines.Therefore, the flow divider valve of this scheme just can be realized the method for salary distribution of any ratios such as one-to-two, a point three, points four, points five.
