Abstract
The invention discloses a diesel engine single body pressure release valve. An oil release hole (3) is formed in the top of a pressure release valve body (1), a sealing steel ball (2) and the oil release hole (3) of an inner cavity of the pressure release valve body (1) contact with each other in a line mode and keep sealing connection, the sealing steel ball (2) is connected with one end of a spring (4) in a contacting mode, the other end of the spring (4) is connected with a hollow greasy blockage (6) in the contacting mode, the hollow greasy blockage (6) is connected with a lower end hole of the pressure release valve body (1) in a matched mode, an adjusting jackscrew (5) on the side wall of the pressure release valve body (1) is connected with the hollow greasy blockage (6) through threads, and a greasy blockage oil outlet (7) is formed in the center of the hollow greasy blockage (6). The diesel engine single body pressure release valve has the advantages of being simple in structure, convenient to install, and capable of effectively solving the problem of complex structure of the modern diesel engine single body pressure release valve, well ensuring stability and reliability of oil pressure of a lubricating system, simplifying assembly process and improving assembly efficiency of a whole engine.
Description
Technical field
The invention belongs to the diesel engine field, be specifically related to a kind of diesel engine monomer Decompression valves.
Background technique
In the diesel engine field, need to adopt Decompression valves that diesel lubrication oil main oil gallery pressure is protected, traditional diesel engine pressure-relief valve structure is complicated, uses inconvenience, and manufacture cost is higher.Monomer pressure-relief valve structure of the present invention is comparatively simple, easy to use, and highly versatile has been saved Design Technology for Diesels, cost of production, has great engineering practical value.
Summary of the invention
The objective of the invention is to reduce the manufacture cost of Decompression valves, and a kind of diesel engine monomer Decompression valves is provided in order to simplify original pressure-relief valve structure.
The technical solution adopted in the present invention is:
a kind of diesel engine monomer Decompression valves, it comprises, pressure release valve body 1, sealed steel ball 2, draining hole 3, spring 4, adjust jackscrew 5, hollow oil stifled 6, the stifled oil outlet 7 of oil, pressure release valve body 1 top is provided with draining hole 3, draining hole 3 lines of sealed steel ball 2 and pressure release valve body 1 inner chamber contact and keep being tightly connected, sealed steel ball 2 is connected with spring 4 one end in contact, spring 4 the other ends are connected with stifled 6 contacts of hollow oil, hollow oil stifled 6 is connected with 1 time stomidium of pressure release valve body, the adjustment jackscrew 5 of pressure release valve body 1 sidewall is connected with hollow oil stifled 6 by screw thread, stifled 6 centers of hollow oil are provided with the stifled oil outlet 7 of oil.
Described sealed steel ball 2 and pressure release valve body 1 inwall gap 0.3mm～0.4mm.
Described draining hole 3 diameters are 4mm～5mm.
The present invention compared with prior art has following beneficial effect:
1) the present invention has adopted the mode of traditional steel ball and spring, has simplified the structure of component, has reduced the quantity of component.
2) the monomer Decompression valves is provided with the engine oil pressure regulating mechanism, can according to the size of the use condition reconditioner oil pressure of diesel engine, satisfy the usage requirement of all kinds of medium and small power diesel engines.
3) the monomer Decompression valves is easy for installation, and is simple and reliable for structure.Monomer Decompression valves outer wall is connected in the interference mode with main oil gallery, and interference clearance is 0.02-0.03mm, guarantees the Decompression valves stable operation.
4) the monomer Decompression valves all process the shape face only have the circle and the plane, without the special form face, the manufacturing cost is low.
Description of drawings
Fig. 1 is structure intention of the present invention.
1. pressure release valve bodies in figure, 2. sealed steel ball, 3. draining hole, 4. spring, 5. adjust jackscrew, and 6. hollow oil is stifled, 7. the stifled oil outlet of oil.
Embodiment
As shown in Figure 1, a kind of diesel engine monomer Decompression valves, comprise, pressure release valve body 1, sealed steel ball 2, draining hole 3, spring 4, adjust that jackscrew 5, hollow oil are stifled 6, the stifled oil outlet 7 of oil, pressure release valve body 1 top is provided with draining hole 3, and sealed steel ball 2 and draining hole 3 form lines and contact and guarantee the machine oil sealing reliably.When the oil duct engine oil pressure surpasses limit value, engine oil pressure crush seal steel ball 2, spring 4 is compressed, sealed steel ball 2 disengages with pressure release valve body 1, ball valve is opened, machine oil enters pressure release valve body 1 inner chamber by draining hole 3 on pressure release valve body 1, and the oilhole 7 by the hollow oil in bottom stifled 6 enters oil sump, reaches the draining purpose.When the oil duct engine oil pressure descends; under the effect of spring 4 restoring forces; spring 4 length increase; sealed steel ball 2 is to draining hole 3 position movements of monolithic valve body 1; until engine oil pressure and spring restoring force balance; steel ball 2 forms the line contact sealing form again with monolithic valve body 1, thereby makes oil duct pressure keep constant, reaches the purpose of protection oil duct pressure.
In the present invention, the large I of monomer Decompression valves working pressure is regulated according to the actual applying working condition of diesel engine, change the reduction length of spring 4 with the working pressure of change whole system by the position of adjusting hollow oil stifled 6, and guaranteed the positional accuracy of hollow oil stifled 6 by the adjustment jackscrew 5 of pressure release valve body 1 sidewall.
Monomer Decompression valves of the present invention is installed simple, and the interference of monomer Decompression valves is installed on the diesel engine main oil gallery with a need or the oil filter attachment face gets final product, and monomer Decompression valves and main oil gallery interference clearance are 0.02mm～0.03mm.The present invention has simplified assembly technology, can effectively improve the efficiency of assembling of complete machine.
