Description
Technical field
The present invention relates to a kind of ZS series banked direction control valves reversal valve.
Background technology
ZS series banked direction control valves reversal valve is the Combined-type sheet-type valve of a kind of manual reverse of direction, and it is mainly used in engineering machinery, mining machinery, handling machinery and other machinery hydraulic systems, with flow direction change, it is achieved the centralized Control of multiple actuators.ZS series banked direction control valves reversal valve goes wrong most positions just at oil-feed pressure regulation assembly during using.Owing to the valve seat of oil-feed pressure regulation assembly uses interference fit with valve body, need to assemble with special tooling during assembling, higher to assembling skill set requirements, also need when being replaced after the prooving of valve seat to carry out with special tooling, bring certain difficulty to assembling and maintenance.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the present invention provides a kind of ZS series banked direction control valves reversal valve so that it is need not special tooling when assembling and maintenance valve seat and just can conveniently carry out.
The technical solution adopted for the present invention to solve the technical problems is: designed ZS series banked direction control valves reversal valve includes valve body, valve seat, main valve plug, valve pocket, main valve plug spring, carries valve seat
, poppet valve, pressure spring, spring base, adjusting nut, locking nut
, protecgulum, combination mat, O and back-up ring, valve seat uses matched in clearance with valve body, and with O and retaining ring sealing, valve seat uses matched in clearance with valve pocket, main valve plug uses matched in clearance with valve seat, carrying valve seat and use matched in clearance with valve pocket, with seal with O ring, valve pocket uses with valve body threadeds, seal by combination mat, valve pocket front end and valve body use matched in clearance, and protecgulum uses with valve pocket threadeds, and seals by combination mat.
The operation principle of the present invention is: owing to valve seat uses matched in clearance with valve body, with O and retaining ring sealing, valve pocket uses with valve body threadeds, seal by combination mat, valve pocket front end uses matched in clearance with valve body, after unscrewing valve pocket, it is possible to carrying valve seat, main valve plug spring, main valve plug, valve seat take out together.
The invention has the beneficial effects as follows: this valve is very convenient when assembling and field maintenance, and layman also can be carried out rapidly.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
1. valve bodies, 2. valve seat, 3. main valve plug, 4. valve pocket, 5. main valve plug spring in figure, 6. carry valve seat, 7. poppet valve, 8. pressure regulation bullet, 9. spring base, 10. adjusting nut, 11. locking screws, 12. protecgulums, 13-14. combination mat, 15-16.O shape circle, 17. back-up rings.
Detailed description of the invention
As can be seen from Figure 1, the embodiment of the present invention includes valve body (1), valve seat (2), main valve plug (3), valve pocket (4), main valve plug spring (5), carries valve seat (6), poppet valve (7), pressure spring (8), spring base (9), adjusting nut (10), locking nut (11), protecgulum (12), combination mat (13), combination mat (14), O (15), O (16) and back-up ring (17).Valve seat (2) uses matched in clearance with valve body (1), seal with O (16) and back-up ring (17), valve seat (2) uses matched in clearance with valve pocket (4), main valve plug (3) uses matched in clearance with valve seat (2), carry valve seat (7) and use matched in clearance with valve pocket (4), seal with O (15), valve pocket (4) uses with valve body (1) threadeds, seal by combination mat (13), valve pocket (4) front end uses matched in clearance with valve body (1), protecgulum (12) uses with valve pocket (4) threadeds, (14) are sealed by combination mat.
Owing to valve seat (2) uses matched in clearance with valve body (1), seal with O (16) and back-up ring (17), valve pocket (4) uses with valve body (1) threadeds, seal by combination mat (13), valve pocket (4) front end uses matched in clearance with valve body (1), after unscrewing valve pocket (4), it is possible to carrying valve seat (6), main valve plug spring (5), main valve plug (3), valve seat (2) take out together.
