Description
Technical field
The utility model relates to a kind of Novel hydraulic valve, belongs to mechanical field.
Background technique
Hydrovalve be a kind of pressure oil operation Automation Elements, it be stressed oil control, be generally used for control oil, gas, water piping system break-make.In diesel engine cooling system, need a kind of hydrovalve low temperature refrigeration water lines and high-temperature cooling water line isolation come, it requires the switch of the force control hydraulic pressure valve using diesel oil owner oil pipe.At present, the similar hydrovalve Heavy Weight that market occurs, volume is large, and structure is compact not, and speed of response is slow, leakage of oil, leaks and not easily discovers, the shortcomings such as maintenance is inconvenient.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of Novel hydraulic valve, it solves that similar hydrovalve weight is large, volume is large, structure is compact not, speed of response is slow, the problem of inconvenient inspection and maintenance.
Technical problem to be solved in the utility model is taked following technological scheme to realize:
A kind of Novel hydraulic valve, it comprises housing, spool, controlling device, and described housing comprises upper cover, cylinder body, valve body, lower cover, is covered with lubricating oil entrance on described, described upper cover, cylinder body, valve body are integrally fixed by stay bolt, and fix with lower cover, form an oil pocket and a water cavity, described spool upper end is positioned at oil pocket, lower end is positioned at water cavity, described controlling device inserts oil pocket by upper cover, and is fixed by nut and pad and upper cover, its lower end and spool upper-end contact.
As preferred embodiment, described spool comprises connecting rod, piston, spring, water valve cap, water valve seat.
As preferred embodiment, described piston is fixed on connecting rod upper end by double nut and pad.
As preferred embodiment, piston, on connecting rod, is connected with cylinder body by described spring housing.
As preferred embodiment, described water valve cap, water valve seat are fixed on connecting rod lower end by double nut and pad, water cavity are separated into water-inlet cavity and water chamber.
As preferred embodiment, described controlling device comprises adjusting screw rod and push rod.
As preferred embodiment, described adjusting screw rod lower end and push rod upper end are fixed.
As preferred embodiment, described cylinder body is provided with a vent.
The beneficial effects of the utility model are: by the redesign to hydrovalve structure, make its weight saving, volume reduces, more compact structure, speed of response accelerates, by the vent arranged on cylinder body, both can reduce the interference of air-flow in cylinder body, piston whether leakage of oil can be checked again, leak.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of hydrovalve housing;
Fig. 3 is the structural representation of hydrovalve spool;
Fig. 4 is the structural representation of hydrovalve controlling device.
Embodiment
In order to technological means of the present utility model, creation characteristic, reach object and effect is easy to understand, below in conjunction with concrete diagram, set forth the utility model further.
As Figure 1-4, a kind of Novel hydraulic valve, it comprises housing 1, spool 2, controlling device 3, described housing 1 comprises upper cover 11, cylinder body 12, valve body 13, lower cover 14, upper cover 11 is provided with lubricating oil entrance 11b, upper cover 11, cylinder body 12, valve body 13 are integrally fixed by stay bolt 6, and fix with lower cover 14, form an oil pocket 11a and water cavity 13a, spool 2 upper end is positioned at oil pocket 11a, and lower end is positioned at water cavity 13a, and controlling device 3 inserts oil pocket 11a by upper cover 11, and fixed with upper cover 11 by nut 4 and pad 5, its lower end and spool 2 upper-end contact.Spool 2 comprises connecting rod 21, piston 22, spring 23, water valve cap 24, water valve seat 25.Piston 22 is fixed on connecting rod 21 upper end by double nut 4 and pad 5.Spring 23 is enclosed within connecting rod 21, is connected by piston 22 with cylinder body 12.Water valve cap 24, water valve seat 25 are fixed on connecting rod 21 lower end by double nut 4 and pad 5, water cavity 13a are separated into water-inlet cavity 13b and water chamber 13c.Controlling device 3 comprises adjusting screw rod 31 and push rod 32.Adjusting screw rod 31 lower end and push rod 32 upper end are fixed.Cylinder body 12 is provided with a vent 12a.
This hydrovalve is arranged on water pipe, and lubricating oil entrance 11b is connected with diesel oil owner oil pipe.When diesel engine runs well, lubricating oil pressure is 0.4 ~ 0.55MPa, and lubricating oil enters oil pocket 11a by lubricating oil entrance, and the pretightening force that promotion piston 22 overcomes spring 23 moves downward.
The cracking pressure of this valve setting is 0.35MPa, and when reaching this force value, piston 22 drives water valve cap 24, water valve seat 25 etc. downward, and water-inlet cavity 13b is communicated with water chamber 13c, and water can left and right circulation.The close value of this valve setting is 0.2MPa.When diesel engine shuts down, lubricating oil pressure makes zero gradually.Now oil pressure reduces until disappear, piston 22 under the effect of spring 23 on move, cut off water-inlet cavity and water chamber, close water pipe.
By the adjustment to the double nut 4 bottom adjusting screw rod 31 and connecting rod 21, pad 5 structure, the pretightening force of spring 23 can be adjusted, make it to reach predetermined design requirement, and when spring 23 lost efficacy, emergent hand switch valve can be carried out by the double nut 4 of connecting rod 21 upper end, pad 5.
Vent 12a both can avoid piston 22 to move by the interference of chamber internal air pressure, monitors oil, water can have ne-leakage again.
More than show and describe basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
