Abstract
A kind of plunger pump hydraulic remote controller, including valve body, spool, reset spring, adjust screw, far control mouth, pipe fitting, overflow valve and oil duct, it is characterized in that being provided with P1 mouthfuls, P2 mouthfuls, C mouthfuls and T mouthfuls on the spool, spool is arranged in valve body, the right side of spool is arranged in the reset spring, the right side of reset spring is arranged in the adjusting screw, and the remote control mouth is connected by oil duct with P1 mouthfuls, and the overflow valve is connected by pipe fitting with remote control mouth；It is installed on plunger pump by what the external overflow valve of pipeline can be convenient, realizes the remote control function to outlet of plunger pump pressure, pressure control is more accurate, and the external direction valve of pipeline starts plunger pump with lower operating pressure, practical.
Description
Technical field
The utility model relates to plunger pump technique field more particularly to a kind of plunger pump hydraulic remote controllers.
Background technique
Traditional plunger pump pressure controller is integrated on plunger pump, and the adjusting of the maximum pressure of outlet of plunger pump must be deep
Enter into pumping plant and carry out, has high requirements for the adjusting space of plunger pump pressure controller, adjusting accuracy, comfort level,
Very big difficulty is brought for the design of integrated hydraulic system in this way.
Summary of the invention
To solve the above-mentioned problems, the utility model provides a kind of plunger pump hydraulic remote controller, provides one kind
The control valve of long-range control plunger pump.To achieve the above object, a kind of technical solution that the utility model is taken are as follows: plunger pump use
Hydraulic remote controller, including valve body, spool, reset spring, adjusting screw, far control mouth, pipe fitting, overflow valve and oil duct, institute
P1 mouthfuls, P2 mouthfuls, C mouthfuls and T mouthfuls are provided on the spool stated, spool is arranged in valve body, and the reset spring is arranged in spool
Right side, the adjusting screw is arranged in the right side of reset spring, and the remote control mouth is connected by oil duct with P1 mouthfuls, institute
The overflow valve stated is connected by pipe fitting with remote control mouth.
It compared with prior art, the utility model has the following beneficial effects: can be square by the external overflow valve of pipeline
Being installed on plunger pump just, realizes the remote control function to outlet of plunger pump pressure, pressure control is more accurate, outside pipeline
The direction valve connect starts plunger pump with lower operating pressure, practical.
Detailed description of the invention
The utility model is described in further detail below in conjunction with attached drawing.
Attached drawing 1 is the structural schematic diagram of the utility model；
In attached drawing: 1, valve body, 2, spool, 3, P1 mouthfuls, 4, P2 mouthfuls, 5, C mouthfuls, 6, T mouthfuls, 7, reset spring, 8, adjusting screw,
9, mouth, 10, pipe fitting, 11, overflow valve are far controlled.
Specific embodiment
In order to enable those skilled in the art to better understand the technical solutions of the present invention, with reference to the accompanying drawing 1 and tool
Body embodiment is further described the utility model.
As shown in Fig. 1, a kind of plunger pump hydraulic remote controller, including valve body 1, spool 2, reset spring 7, adjusting
Screw 8 far controls mouth 9, pipe fitting 10, overflow valve 11 and oil duct, is provided with P1 mouth 3, P2 mouth 4, C mouth 5 and T on the spool 2
Mouth 6, spool 2 are arranged in valve body 1, and the right side of spool 2 is arranged in the reset spring 7, and the setting of adjusting screw 8 exists
The right side of reset spring 7, the remote control mouth 9 are connected by oil duct with P1 mouth 3, and the overflow valve 11 passes through pipe fitting 10
It is connected with remote control mouth 9.
Further, direction valve can replace overflow valve 11 to be connected with pipe fitting 10.
The working principle and the course of work of the utility model are as follows: valve body 1 is fastened by bolts in the side of plunger pump, with
Each control port of plunger pump is connected；The pressure oil of plunger pump oil outlet is through 3 → spool of P1 mouth 2 → remote control 9 → pipe fitting of mouth
10, eventually flow to overflow valve 11；
When pressure is not up to 11 preset pressure value of overflow valve, spool 2 is in the normal state position, at this time C mouth 5 and T
Mouth 6 is connected, and plunger pump is in displacement；When pressure reaches 11 preset pressure value of overflow valve, spool 2 is right
It moves, at this time P2 mouth 4 and the connection of C mouth 5, the oil inlet of plunger pump is by C mouthfuls of outflows, and plunger pump is by variable to close to zero delivery；Therefore
It may be implemented to control the remote pressure of plunger pump oil outlet by changing the pressure value that overflow valve 11 is set, adjust screw 8 and rise
To the effect for adjusting 7 pretightning force of reset spring, facilitate debugging.
When pipe fitting 10 connects direction valve, when direction valve is in the open state, it is derived from the control oil of outlet of plunger pump directly
Oil return box can start plunger pump with lower operating pressure, reach energy-efficient effect.
It compared with prior art, the utility model has the following beneficial effects: can be square by the external overflow valve of pipeline
Being installed on plunger pump just, realizes the remote control function to outlet of plunger pump pressure, pressure control is more accurate, outside pipeline
The direction valve connect starts plunger pump with lower operating pressure, practical.
Using technical solution described in the utility model or those skilled in the art in technical solutions of the utility model
Under inspiration, similar technical solution is designed, and reaches above-mentioned technical effect, is the protection model for falling into the utility model
It encloses.
