Abstract
The utility model discloses a switching block for hydraulic control. The switching block comprises a switching block body, wherein a throttle valve seat is fixed at the lower end of the switching block body, a throttle cap is fixed at the upper end of the switching block body, and a throttle valve core is fixed in the inner cavity of the throttle cap. A switching block port A, an oil inlet P, a connecting oil cylinder port B and an oil return port T are arranged on the switching block body. A magnetic exchange valve is further connected onto the switching block body. By arranging the switching block on a hydraulic oil cylinder, a hydraulic system control element is directly installed on the oil cylinder, a hydraulic system only outputs a main pipe, each control oil cylinder is only connected with an oil inlet branch pipe and an oil return branch pipe on the main pipe, hydraulic oil pipes are obviously decreased, the cost and occupied area are also controlled, and hydraulic faults are obviously decreased. In addition, the miniaturization of the whole switching block is achieved, and maintainability is good.
Description
Technical field
The utility model relates to a kind of control gear, particularly the pipeline conversion control device of the integrated utilization of a kind of Hydraulic Industry hydraulic parts.
Background technique
In hydraulic system, pipeline refers to the pipeline that transmits working fluid in hydraulic system, is the pipe made from metal or other materials, gets up by certain design and installation, industrial or architectural conveying or the eliminating fluid of being used for.On pipeline, be provided with control valve, in the thicker situation of pipeline, control valve is all larger, generally carrys out control valve by hydraulic jack, many at pipeline, while needing centralized control, be generally that hydraulic control valve is focused on to (or independent place) in system, the easy like this installation oil pipe pipeline that causes is many and complicated, the distance of control unit and hydraulic jack, cost is high, and floor space is large, and hydraulic fault also easily occurs.
Model utility content
The purpose of this utility model is to provide a kind of hydraulic control conversion block, controls oil cylinder for every and on main line, only picks out into, return tube and divide pipeline, and it can be realized the speed control of oil cylinder and flexiblely turn to control.
For achieving the above object, technical solution adopted in the utility model is:
This conversion block comprises conversion block, and the lower end of conversion block is fixed with throttle valve seat, the upper end fixed restriction block of conversion block, and throttling block inner chamber is fixed with throttling valve core; On conversion block, be provided with conversion block A mouth, oil-feed P mouth, connect oil cylinder B mouth and oil return T mouth; On conversion block, be also connected with solenoid directional control valve.
Preferably, on throttling block, be connected with block.
Preferably, oil-feed P mouth is connected with conversion block P lid.
Preferably, connect oil cylinder B mouth and be connected with straight coupling, on straight coupling, have straightthrough port.
The beneficial effect that the utility model produces is:
HYDRAULIC CONTROL SYSTEM element is directly installed on oil cylinder, hydraulic system is only exported main line, controls oil cylinder for every and on main line, only picks out into, return tube and divide pipeline, and hydraulic oil pipe pipeline obviously reduces, cost and floor space are also controlled, and hydraulic fault obviously reduces.Simultaneously conversion block is whole realizes miniaturization, and maintainalbility is good.
Brief description of the drawings
Fig. 1 is the main TV structure schematic diagram of conversion block.
Fig. 2 is conversion block plan structure schematic diagram.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
As shown in Figure 1 and Figure 2, this conversion block comprises conversion block 1, and the lower end of conversion block 1 is fixed with throttle valve seat 2, the upper end fixed restriction block 3 of conversion block 1, and throttling block inner chamber is fixed with throttling valve core 4; On conversion block 1, be provided with conversion block A mouth 11, oil-feed P mouth 7, connect oil cylinder B mouth 8 and oil return T mouth 10; On conversion block 1, be also connected with solenoid directional control valve 12.
This hydraulic control by a kind of preferred implementation of conversion block is, on throttling block 3, is connected with block 5, for preventing that dust from entering conversion block inside, extends the working life of conversion block.
This hydraulic control is that described oil-feed P mouth 7 is connected with conversion block P lid 6, is convenient to be connected with pipeline on the one hand, has also simplified on the other hand the processing of conversion block 1 by a kind of preferred implementation of conversion block.
This hydraulic control is that described connection oil cylinder B mouth 8 is connected with straight coupling 9, has straightthrough port 13 on straight coupling 9, is convenient to be connected with pilot line on the one hand, also can realize the connection that turns to pilot line simultaneously by a kind of preferred implementation of conversion block.
The working principle of conversion block is as follows:
Pressing system output main pipe pressure P mouth and oil return T mouth be to the operating cylinder of workshop, operating cylinder and conversion block A mouth 11 be connected oil cylinder B mouth 8 and connect, conversion block is on oil cylinder head.Conversion block oil-feed P mouth 7, oil return T mouth 10 connect respectively hydraulic system output main pipe pressure P mouth and oil return T mouth, complete connection.Oil-feed P mouth 7 is by throttling valve core 4 adjust fluxes, and by the turnover oil flow of solenoid directional control valve 12 and throttling valve core 4 oil cylinder with controllable A mouths and B mouth, the hydraulic oil that A mouth and B mouth discharge is got back to oil return T mouth connecting base, enters system oil return T mouth by being in charge of.Realizing oil cylinder can knee-action, also can realize speed adjustment according to action request, can realize the speed control of oil cylinder and flexiblely turning to control.
Although the utility model has been made to detailed description with above-mentioned preferred embodiment, has not limited the utility model with above-described embodiment.Those skilled in the art should recognize in the case of not departing from technical solutions of the utility model given technical characteristics and scope; increase that technical characteristics is done, with the replacement of some same contents of related domain, all should belong to protection domain of the present utility model.
