Abstract
The utility model discloses a combination valve with an operating mechanism, i.e. a manual combination proportional valve, consisting of a manual changeover valve and a proportional pressure regulator. The proportional pressure regulator consists of a proportional pressure valve, a shuttle valve and a controlling device; therefore, the working pressure of the manual combination proportional valve does not change along with the loading, thus realizing constant pressure control. The automatic flux control can help the utility model realize stepless variable speed, and the utility mode employs a tube type connection, thus making assembly convenient.
Description
One, technical field
The utility model relates to a kind of control valve, particularly relates to the combination valve of the vertical mechanism of a kind of ribbon gymnastics, goes into F16K15/18.
Two, background technique
Hand-operated direction valve generally all adopts hand lever or mechanical push rods to handle the direction of spool displacement at present, to realize communication, cut-out and the direction transformation of control oil stream.This valve manually-operable is more convenient, also need not power supply.But work the time exists working pressure and changes with load variations, can not use for the occasion of the pressure-controlled that requires to weigh, moreover the Placement of this valve can only be board-like connection, can not adopt tubular type to connect, and inconvenience is installed.
Three, model utility content
The purpose of this utility model is that a kind of novel selector valve that can overcome the existing existing defective of hand-operated direction valve will be provided---manual compositely proportional valve, this novel manual compositely proportional valve can adopt following technological scheme to implement: it is made up of hand-operated direction valve and proportional pressure reducing piece two parts, and the structure of hand-operated direction valve and operating principle and general hand-operated direction valve are same or similar.And the proportional pressure reducing piece by fixed than valve body and be installed in fixed than the Proprutioning pressure reducing valve in the valve body, shuttle valve, form surely than component such as control gear.Wherein Proprutioning pressure reducing valve is made up of reduction valve back seat, reduction valve spool, stage clip etc., and shuttle valve is made up of shuttle valve locking lever, lower valve base, shuttle valve spool and shuttle valve valve pocket etc., decides to be made up of regulating spool, locking nut, back control lid than control gear.Proprutioning pressure reducing valve is directly installed on fixed than in the valve body, and regulating spool is contained in the back control lid.
The manual compositely proportional valve of forming according to said structure is compared with existing hand-operated direction valve has following advantage:
1, manually the compositely proportional valve is to constitute after installing the proportional pressure reducing piece additional on the basis of hand-operated direction valve, thereby manually compositely proportional valve working pressure does not change with load, and it is fixed to remain weighing apparatus: 2, flow is controlled automatically, can realize stepless change; 3, hand-operated direction valve can only board-likely connect, and manually the compositely proportional valve is that tubular type connects, and is easy for installation.

Five, embodiment
Manual compositely proportional valve of the present utility model can be implemented according to Fig. 1, Fig. 2, mode shown in Figure 3: it is made up of hand-operated direction valve (1) and proportional pressure reducing piece two parts, wherein the proportional pressure reducing piece by fixed than valve body (2) and be installed in fixed than the Proprutioning pressure reducing valve in the valve body (2), shuttle valve, form surely than component such as control gear.Wherein Proprutioning pressure reducing valve is made up of reduction valve back seat (3), reduction valve spool (4), stage clip (10) etc., and shuttle valve is made up of shuttle valve locking lever (5), lower valve base (6), shuttle valve spool (7) and shuttle valve valve pocket (8), decides to be made up of regulating spool (11), locking nut (12), back control lid (9) than control gear.Proprutioning pressure reducing valve, shuttle valve are directly installed on fixed than in the valve body (2), and regulating spool is contained in the back control lid.During the manual compositely proportional valve work formed according to said structure as shown in Figure 4: when the oil-feed of P chamber,,, realized the weighing apparatus pressure-controlled so the pressure of P1 mouth is not influenced by P mouth pressure size when the oil-feed of P mouth because of the P mouth has been installed Proprutioning pressure reducing valve (01).When the handle of hand-operated direction valve (02) when (direction as shown) is mobile to the right, shuttle valve spool when fluid flows into B chamber (this moment, the A chamber communicated with the P chamber) through the P chamber in the shuttle valve (04) is moved to the left, the A chamber is closed, shuttle valve is controlled the logical oil mass of how much controlling Proprutioning pressure reducing valve (01) of oily flow with the handle displacement, realizes the automatic control of flow; When the handle of hand-operated direction valve (02) is pulled out left, fluid flows into the A chamber through the P chamber, the B chamber flows into the T chamber, the interior spool displacement to the right of shuttle valve this moment, close the B chamber, control Proprutioning pressure reducing valve simultaneously, make its logical oil mass control (also promptly controlling the logical oil mass of P1), realize the automatic control of flow equally to A by the handle displacement amount.
Claims (4)
1, a kind of manual compositely proportional valve of forming by hand-operated direction valve (1) and proportional pressure reducing piece, it is characterized in that the proportional pressure reducing piece by fixed than valve body (2) and be installed in fixed than the Proprutioning pressure reducing valve in the valve body (2), shuttle valve, form surely than control gear.
2, manual compositely proportional valve according to claim 1 is characterized in that Proprutioning pressure reducing valve is made up of reduction valve back seat (3), reduction valve spool (4), stage clip (10) etc.
3, manual compositely proportional valve according to claim 1 is characterized in that shuttle valve is made up of shuttle valve locking lever (5), lower valve base (6), shuttle valve spool (7) and shuttle valve valve pocket (8).
4, manual compositely proportional valve according to claim 1 is characterized in that deciding being made up of regulating spool (11), locking nut (12), back control lid (9) than control gear.
