Description
Technical field
The present invention relates to a kind of steering wheel special service valve, particularly a kind of plug-in pilot control steering wheel special service valve.
Background technology
Since reform and opening-up, national economy obtains rapid growth, and " scientific and technical innovation, autonomous innovation " has turned into domestic work at present
The main flow of industry development, China's industry just progressively develops to the direction of intensive style, energy-saving and emission-reduction, low-carbon.Traditional steering wheel is special
Valve, can only use the structure control of side valve type, and sliding valve structure has two big defects：1st, oil filling capacity is restricted, it is impossible to met
Big steering wheel rotary speed, internal leakage hardly possible control, steady rudder performance is poor.To improve the diameter of steering wheel special service valve, it has to increase
The diameter of guiding valve, so the steering wheel special service valve for big orifice, its contour structures will be larger.The increase of diameter, sliding spool with
The fit-up gap of valve body will also increase, and so interior leakage is also multiplied, and internal leakage increase has a strong impact on the auto-lock function of steering wheel.
2nd, steering wheel special service valve is after several years or decades have been used, due to the permanent relative motion of valve element and valve body, valve element and valve body
Fit clearance can increase, internal leakage also can accordingly increase over time, it may appear that serious to run rudder phenomenon so that guiding valve
The steering wheel valve lost of life of formula.Therefore for large-scale steering wheel, the steering wheel special service valve of big orifice is redesigned, it appears very
It is important.In order to solve the above problems, scientific research personnel of the same trade and technical staff are constantly changed by continuous research and discovery
Enter existing Wen mouthful, although technically make some progress, but remain and not yet overcome in practice
Technical barrier.
The content of the invention
It is an object of the invention to overcome above deficiency there is provided a kind of plug-in pilot control steering wheel special service valve, using inserted valve
The cone valve type structure of formula, unlatching and the closure of cone valve use pilot control, and pilot valve is by control of itself surging, simple in construction
It is compact, lead to oil flow greatly, steering wheel rotary speed is fast, and auto-lock function is realized in stable and reliable operation, and internal leakage is several when using
Keep constant, overcome negative torque, have a safety feature, extend the service life of steering wheel special service valve, improve operating efficiency.
The technical solution adopted for the present invention to solve the technical problems is：Containing pilot valve, inserted valve, direct acting type overflow valve,
The top of plug-in pilot control steering wheel special service valve, which is provided with below pilot valve, pilot valve, is provided with inserted valve, inserted valve and guide
Valve is provided with direct acting type overflow valve into plumbness below inserted valve, direct acting type overflow valve and inserted valve are into plumbness, group
Into a kind of plug-in pilot control steering wheel special service valve.
The present invention solves the technical principle that is used of its technical problem：As shown in Figure 1, 2, 3, when A1 oil-feeds, first
Pilot valve is surged commutation, and into the left position of valve, inserting valve core top hydraulic oil, into B1, cone valve is opened；When B1 oil-feeds
When, pilot valve is surged commutation, and into the right position of valve, inserting valve core top hydraulic oil, into A1, cone valve is opened；Work as rudder
When reversal valve in machine hydraulic system answers middle position, steering wheel is at not steering state, A1 and B1 not oil-feeds simultaneously, pilot valve
In middle position, A2 or any one end oil-feeds of B2, inserted valve are under self-locking state all in closed mode, therefore the special valve of steering wheel,
Realize the auto-lock function of steering wheel special service valve.A kind of plug-in pilot control steering wheel special service valve is two direct acting type overflows of inserting
Valve, using the cone valve type structure of inserting valve type, unlatching and the closure of cone valve use pilot control, and pilot valve surges by itself
Control, it is simple and compact for structure, lead to oil flow greatly, steering wheel rotary speed is fast, and auto-lock function is realized in stable and reliable operation, is made
Used time internal leakage is kept approximately constant, and overcomes negative torque, is had a safety feature, and extends the service life of steering wheel special service valve,
Improve operating efficiency.
The beneficial effects of the invention are as follows：A kind of plug-in pilot control steering wheel special service valve is two direct acting type overflow valves of inserting,
Big with oil filling capacity, noise is low, the advantages of good reliability, and a kind of plug-in pilot control steering wheel special service valve uses inserted valve
The cone valve type structure of formula, unlatching and the closure of cone valve use pilot control, and pilot valve is by control of itself surging, simple in construction
It is compact, lead to oil flow greatly, steering wheel rotary speed is fast, and auto-lock function is realized in stable and reliable operation, and internal leakage is several when using
Keep constant, overcome negative torque, have a safety feature, extend the service life of steering wheel special service valve, improve operating efficiency.
Brief description of the drawings
Here is that the present invention is further described in conjunction with the accompanying drawings and embodiments：
It is a kind of left view of plug-in pilot control steering wheel special service valve in Fig. 1；
It is a kind of G-G sectional views of plug-in pilot control steering wheel special service valve in Fig. 2；
It is a kind of M-M sectional views of plug-in pilot control steering wheel special service valve in Fig. 3；
In Fig. 1,2,3：1st, pilot valve, 2, inserted valve, 3, direct acting type overflow valve.
Embodiment
In Fig. 1,2,3：The top of plug-in pilot control steering wheel special service valve is provided with below pilot valve, pilot valve and is provided with
Inserted valve, inserted valve and pilot valve are provided with direct acting type overflow valve into plumbness below inserted valve, direct acting type overflow valve with
Inserted valve constitutes a kind of plug-in pilot control steering wheel special service valve into plumbness.
As shown in Figure 1, 2, 3, when A1 oil-feeds, pilot valve surges commutation, into the left position of valve, on inserting valve core
Portion's hydraulic oil, into B1, cone valve is opened；When B1 oil-feeds, pilot valve surges commutation, into the right position of valve, inserted valve
Valve element top hydraulic oil, into A1, cone valve is opened；When the multiple middle position of the reversal valve in steering gear hydraulic system, steering wheel is in not
Steering state, A1 and B1 not oil-feed simultaneously, pilot valve are in middle position, A2 or any one end oil-feeds of B2, and inserted valve is all located
In closed mode, therefore the special valve of steering wheel realizes the auto-lock function of steering wheel special service valve under self-locking state.
A kind of plug-in pilot control steering wheel special service valve is two direct acting type overflow valves of inserting, big with oil filling capacity, noise
Low, the advantages of good reliability, a kind of plug-in pilot control steering wheel special service valve is using the cone valve type structure of inserting valve type, cone valve
Unlatching and closure use pilot control, and pilot valve is by control of itself surging, simple and compact for structure, leads to oily flow greatly, rudder
Machine rotary speed is fast, and auto-lock function is realized in stable and reliable operation, and internal leakage is kept approximately constant when using, and overcomes negative twist
Square, has a safety feature, and extends the service life of steering wheel special service valve, improves operating efficiency.
