Abstract
The invention relates to a pressure-operated valve comprising a valve body. The valve body is arranged on a base, a pressure adjusting device connected with the valve body is also arranged on the base, the valve body is provided with two support rods, a pressure gage is arranged on the support rods, and two oil pipe joints are arranged on the valve body. As the pressure gage is matched with the pressure adjusting device, when the pressure at the tail end of one main pipeline during oil supply exceeds a preset pressure, the pressure-operated valve sends out information to an electrical cabinet, and the alternative oil supply of two main oil supply pipes is realized by virtue of an electromagnetic directional valve. The pressure-operated valve has a simple structure, and can be used for sending signals correctly and reliably.
Description
Technical field
The present invention relates to a kind of pressure-operated valve in the mechanical field application.
Background technique
The control valve of transmission is the commutation that realizes control valve by Joystick, and the control valve upper handle is more, and it is very inconvenient to operate, and working efficiency is low, simultaneously staff's personal safety is caused certain threat.
Summary of the invention
In order to overcome defects, the invention provides a kind of pressure-operated valve, simple in structure, transmitted signal is correct, the setting pressure capable of regulating.
The technical solution adopted for the present invention to solve the technical problems is: a kind of pressure-operated valve, comprise valve body, valve body is arranged on the base, also be provided with the pressure regulation device that is connected with valve body on the base, valve body is provided with two struts, strut is provided with pressure gauge, also is provided with two oil connections on the valve body.
The pressure adjustment range of pressure regulation device is 3MPa to 6MPa
The invention has the beneficial effects as follows: being used of pressure gauge and pressure regulation device, so that the terminal pressure when the main pipe fuel feeding is when surpassing predetermined pressure, pressure-operated valve will send information to electric control cubicle, realized two oil supply bars' alternately fuel feeding by solenoid directional control valve, simple in structure, transmitted signal is correct, and is reliable.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the plan view of Fig. 1.
Among the figure: 1, valve body; 2, base; 3, pressure regulation device; 4, strut; 5, pressure gauge; 6, oil connection.
Embodiment
Describe the present invention below in conjunction with the drawings and the specific embodiments: such as Fig. 1 to a kind of pressure-operated valve shown in Figure 2, comprise valve body 1, valve body 1 is arranged on the base 2, also be provided with the pressure regulation device 3 that is connected with valve body 1 on the base 2, valve body 1 is provided with two struts 4, strut 4 is provided with pressure gauge 5, also is provided with two oil connections 6 on the valve body 1, is used for installing oil supply pipeline; The pressure adjustment range of pressure regulation device 3 is 3MPa to 6MPa, adjusts scheduled pressure value according to field condition.
Pressure-operated valve is a kind of signal transmitter that utilizes the pressure difference signal to be converted into electrical signal by mechanical transmission, be used for electronic terminal type grease concentrating lubricating system, be installed on the end in two oil supply bar roads, when the terminal pressure when the main pipe fuel feeding surpasses the setting pressure of this valve, this valve events sends signal to electric control cubicle, realized two oil supply bars' alternately fuel feeding by solenoid directional control valve, this valve transmitted signal is correct, reliably, the pressure of setting can be adjusted, simple in structure, transmitted signal is correct, and is reliable.
It is emphasized that: above only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment does.
