Problems solved by technology

[0003] Most of the existing pneumatic control technologies for constant value devices on the market are gas-consumption balanced pressure regulation, which will lose a considerable part of the gas, which is not conducive to the economical operation of the diesel engine.
At the same time, some regulators cannot realize the continuous adjustment of the output air pressure.

Embodiment Construction

[0020] refer to Figure 1 to Figure 3 , which shows the specific structure of the preferred embodiment of the present invention. The structural features of each part of the present invention will be described in detail below, and if there is a description to the direction (up, down, left, right, front and back), it is based on figure 2 The shown structure is a reference description, but the actual use direction of the present invention is not limited thereto.

[0021] The present invention provides a diesel engine side-operated constant value device capable of steplessly regulating air pressure, comprising a housing 1, a sliding sleeve 2, a valve stem 3 and a valve seat piston 4, and the housing 1 is provided with a sliding sleeve The sliding chamber 11 and the valve seat piston sliding chamber 12 located below the sliding chamber 11 of the sliding sleeve. The sliding sleeve 2 is arranged in the sliding chamber 11 of the sliding sleeve. The sliding chamber 11 moves up and d...

Abstract

The invention discloses a control setter beside a diesel engine for stepless voltage regulation of air pressure. The control setter is used for the field of diesel engine manufacturing. The control setter comprises a shell, a sliding sleeve, a valve rod and a valve seat piston; a sliding sleeve sliding cavity and a valve seat piston sliding cavity are arranged in the shell, the sliding sleeve is arranged in the sliding sleeve sliding cavity, and the valve seat piston is arranged in the valve seat piston sliding cavity; the sliding sleeve forms a first air cavity in the sliding sleeve sliding cavity, and a second air cavity is formed in the valve seat piston sliding cavity between the sliding sleeve and the valve seat piston; a first air through hole is formed in the sliding sleeve, and a second air through hole is formed in the valve seat piston; a first valve body and a second valve body are arranged on the valve rod; a valve rod spring is arranged between the sliding sleeve and the valve rod, a sliding sleeve spring is arranged between the sliding sleeve and the valve seat piston, and a balance spring is arranged at the bottom part of the sliding sleeve spring; and an air inlet hole and an air outlet hole are formed in the shell. According to the control setter, during working, high-pressure air is hardly consumed, so that operation cost of the diesel engine is saved; stepless voltage regulation of the output air pressure and stepless speed change of the rotating speed of a crankshaft of the diesel engine are realized; and the control setter is compact in structure, safe,reliable and easy to maintain.

Description

technical field [0001] The invention is used in the field of diesel engine manufacture, and in particular relates to a diesel engine side-operated constant value device capable of steplessly regulating air pressure. Background technique [0002] The constant value device is the pneumatic control element of the diesel engine speed. It is installed on the control box of the diesel engine. When a certain air source pressure is input, a stable air pressure can be output to the speed controller to realize the control of the crankshaft speed of the diesel engine. Its characteristic is generally that the force generated by a given spring and the feedback force generated by the output air pressure are balanced on the comparison element. [0003] Most of the existing pneumatic control technologies for regulators on the market are gas consumption balance type regulators, which will lose a considerable part of the gas, which is not conducive to the economical operation of diesel engine...
