Description
Technical field
The utility model relates to technical field of hydraulic more particularly to a kind of electromagnetism prefill valves.
Background technique
Prefill valve belongs to shut-off valve class, is mainly used for big flow filling liquid or the drain of all kinds of oil cylinders, to improve its idle running speed
Degree and opening speed.Its working principle is similar to hydraulic control one-way valve, and flowing to B from A can flow freely, and it is controllable for flowing to A from B
, when having control oil access for X mouthfuls, check valve is opened, and B flows to A conducting, and when X mouthfuls of pressure releases, closed check valve, B flows to A not
It is logical.Prefill valve has obtained so extensive that apply in the hydraulic system of various machinery, however the filling liquid valve arrangement of the prior art is fixed,
Shape is larger, can not be applied to certain special operation conditions, such as the operating condition that space requirement is compact, and the control oil circuit of prefill valve is longer,
Response time also increases with it, and cannot fully meet the requirement of production.
Summary of the invention
To solve the above-mentioned problems, the utility model provides a kind of electromagnetism prefill valve, provides a kind of compact-sized, shape
The small electromagnetism prefill valve of size.To achieve the above object, the technical solution that the utility model is taken are as follows: a kind of electromagnetism prefill valve,
Including mounting flange, valve seat, main valve plug, valve body, control piston, reset spring, spring base, solenoid valve and bolt, the valve seat
Lower end be set as high-pressure side, the upper end of valve seat is set as low-pressure side, and the lower part of valve seat is arranged in the main valve plug, valve seat
It is internally provided with oil duct, main valve plug and valve seat connect, and the reset spring is connected by spring base with main valve plug, main
Spool is fit together by the pretightning force of reset spring with valve seat, and the top of valve seat is arranged in the mounting flange, fixed
Flange is connected by bolt with valve seat, and the valve body is internally provided with oil duct, and the upper of valve seat is arranged in by bolt in valve body
Portion, the control piston are arranged between spring base and valve body, and the side of mounting flange, electromagnetism is arranged in the solenoid valve
Valve includes prefill valve control mouth, and prefill valve control mouth is connected with the oil duct inside valve seat.
Further, the upper surface of valve seat is provided with compensating groove and seal groove.
Further, compensating groove is set as the Double Circle structure being arranged symmetrically.
Compared with prior art, the utility model has the following beneficial effects: solenoid valve is integrated on prefill valve, make to tie
Structure is more compact, and outer dimension is smaller, is easily installed on the hydraulic cylinder between hydraulic cylinder bottom and prewelding acting flange；Control
Mouth is more reasonable, and cracking pressure is low, circulation is good, self-priming performance is good, improves the reaction time of prefill valve.
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, mounting flange, 2, valve seat, 3, main valve plug, 4, valve body, 5, control piston, 6, reset spring, 7, spring
Seat, 8, solenoid valve.
Specific embodiment
In order to enable those skilled in the art to better understand the technical solutions of the present invention, 1, attached drawing with reference to the accompanying drawing
2 and specific embodiment the utility model is further described.
As shown in attached drawing 1, attached drawing 2, a kind of electromagnetism prefill valve, including mounting flange 1, valve seat 2, main valve plug 3, valve body 4, control
Piston 5, reset spring 6, spring base 7, solenoid valve 8 and bolt processed, the lower end of the valve seat 2 are set as high-pressure side, valve seat 2 it is upper
End is set as low-pressure side, and the main valve plug 3 is arranged in the lower part of valve seat 2, and valve seat 2 is internally provided with oil duct, main valve plug 3 with
Valve seat 2 connects, and the reset spring 6 is connected by spring base 7 with main valve plug 3, and main valve plug 3 passes through reset spring
Pretightning force fits together with valve seat 2, and the mounting flange 1 is arranged in the top of valve seat 2, mounting flange 1 by bolt with
Valve seat 2 is connected, and the valve body 4 is internally provided with oil duct, and the top of valve seat 2, the control are arranged in by bolt for valve body 4
Piston 5 processed is arranged between spring base 7 and valve body 4, and the side of mounting flange 1 is arranged in the solenoid valve 8, and solenoid valve 8 wraps
Prefill valve control mouth is included, prefill valve control mouth is connected with the oil duct inside valve seat 2.
Further, the upper surface of valve seat 2 is provided with compensating groove and seal groove.
