Description

Pressure filter hydraulic controller

Technical field

The utility model relates to a kind of hydraulic controller, particularly relates to the hydraulic controller on a kind of pressure filter.

Background technique

Pressure filter is in fact a kind of solid-liquid separating equipment, in many industry extensive uses such as chemical industry, medicine, food, papermaking.But in existing pressure filter product (if screw type is still in use), production unit is all generally carry out nonstandard production according to self product structure and feature, thus product is single, standardization level is poor, versatility, reliability are not high, from the structure of pressure filter, mechanical type is many, there is no the high performance standard product of hydraulic control, needs people to go research and development.

Summary of the invention

The purpose of this utility model to provide the pressure filter hydraulic controller that a kind of highly versatile, structure are simple, level of integration is high, safe and reliable.

To achieve these goals, the utility model adopts following technological scheme to implement: pressure filter hydraulic controller (hereinafter referred to as hydraulic controller) comprises hydraulic lock, position control valve, high-pressure safety valve, low-pressure safety valve and manifold block, wherein hydraulic lock to be inserted in manifold block and with cover plate by the shutoff of O RunddichtringO, high-pressure safety valve and low-pressure safety valve are plug in packages, can directly insert in manifold block, (because this assembly carries O RunddichtringO, therefore can directly insert in manifold block), position control valve (also can use manually operated valve, explosion-proof valve, solenoid valve, user is had to select) be directly installed on manifold block by screw.

Compared with prior art, its outstanding advantage is the pressure filter hydraulic controller designed and produced according to technique scheme:

1, pressure filter hydraulic controller of the present utility model has pressure holding function, even if there is a small amount of pressure leakage in hydraulic lock under stipulated time, authorized pressure, because device of the present utility model has automatic compensation function, so can keep constant pressure, make ouput force keep constant.

2, oil hydraulic cylinder area ratio is large, oil hydraulic cylinder is caused to damage because rod chamber pressure is high when retreating for preventing rod chamber oil-feed, be provided with safety valve in device of the present utility model, when ensureing oil hydraulic cylinder energy normal reverse, pressure arranged minimum, guaranteeing oil hydraulic cylinder safety.

3, position control valve is standardized structural, also can adopt solenoid valve, explosion-proof valve, manually operated valve, select for user.

4, hydraulic lock, high-pressure safety valve, low-pressure safety valve all adopt reassembling type structure, and compact structure is easy to maintenance.

5, oil inlet P, oil return inlet T and actuator port A and B all adopt and are threaded, installation, maintenance and convenience thereof.

6, in this device, all inherent Sealings all adopt the manufacture of fluorine silica gel material, long service life, and generally available 20 years, temperature performance was good, spend within the scope of high temperature+150 degree sealability all can be kept not change at low temperature-20.

Accompanying drawing explanation

Fig. 1 is the structural representation of the utility model pressure filter hydraulic controller.

Fig. 2 is the fundamental diagram of the utility model pressure filter hydraulic controller.

Embodiment

Face is further described the utility model by reference to the accompanying drawings and under embodiment.

As shown in Figure 1: pressure filter hydraulic controller comprises hydraulic lock 1, position control valve 2, high-pressure safety valve 3, low-pressure safety valve 4 and manifold block 5, wherein hydraulic lock 1 to be inserted in manifold block 5 and with cover plate by the shutoff of O RunddichtringO, high-pressure safety valve 3 low-pressure safety valve 4 is plug in packages, can directly insert in manifold block (because this assembly carries O RunddichtringO, therefore can directly insert in manifold block), position control valve (also can with manually operated valve, explosion-proof valve, solenoid valve, have user to select) is directly installed on manifold block by screw.

During the pressure filter hydraulic controller work made according to said structure form as shown in Figure 2: when fluid is from P mouth approach axis control valve 2; When position control valve 2 mediates, whole oil system is in oil return state, when the left side work of position control valve 2, P mouth and the conducting of oil cylinder B mouth, simultaneously because the pressure of B mouth opens the control mouth of hydraulic lock 1, make hydraulic lock reverse-conducting, namely A mouth is to the conducting of T mouth, the piston rod of oil cylinder is to left movement, and its motion stress is regulated by low-pressure safety valve 4; When position control valve 2 changes the right work into, P mouth is by hydraulic lock forward conduction to A mouth, and B mouth and the conducting of T mouth simultaneously, cylinder piston rod is moved right, and the adjustment of maximum pressure is set by high-pressure safety valve.Above-mentioned P mouth is filler opening, and T mouth is return opening, and A mouth and B mouth are working hole.

High owing to having standardization level by the pressure filter hydraulic controller of said structure composition, compact structure, safe and reliable, easy to maintenance and excellent service behaviour, is widely used on high performance pressure filter, is the upgrading regeneration product of existing product.
