Description
Technical field
The present invention relates to a kind of multi-functional check valve, it is mainly used in diesel engine, belongs to valve technology field.
Background technology
Diesel engine is burning diesel oil to obtain exergonic engine, it has the thermal efficiency and better economy,
Diesel engine improves air themperature using the method for compressed air, air themperature is exceeded the self-ignition point of diesel oil, at this moment sprays into again
Oneself ignition while diesel oil, diesel spray and air mix.Therefore, diesel engine is without ignition system.Meanwhile bavin
The oil supply system of oil machine is also relatively easy, therefore the reliability of diesel engine is better than petrol engine.Due to from quick-fried
The limitation of combustion and the needs of diesel oil spontaneous combustion, diesel engine compression ratio are very high.The thermal efficiency and economy will be better than gasoline engine, at the same time
In the case of equal-wattage, the moment of torsion of diesel engine is big, and rotating speed during maximum power is low, is suitable for the use of cargo vehicle.
It can be used for controlling the logical of oil piping system come the diesel oil that circulates, wherein check valve equipped with many valves in diesel engine
It is disconnected, realize one-way conduction.But conventional check valve is complicated, cumbersome for installation, inefficiency, is installed on big machinery
When need consume the plenty of time.
The content of the invention
The purpose of the present invention is to overcome the above shortcomings and to provide a kind of multi-functional check valve, this multi-functional check valve knot
Structure is simple, and cost is relatively low, and substantially increases installation effectiveness.
The object of the present invention is achieved like this：
A kind of multi-functional check valve, including valve body, the inside of valve body are fixed with valve seat, oil circuit through hole, the valve are provided with valve seat
Seat is equipped with spring base, and the bottom of the spring base covers oil circuit through hole, and the top of spring base is equipped with spring pocket, the spring base
Spring is equipped between spring pocket, the valve seat, spring base and spring pocket are run through from below to up by bolt mutually to be fixed, the spiral shell
Locking nut is equipped with the top of bolt, the bottom and top of the valve body are equipped with flange, are provided with the front side pipeline of the valve body
Alarm, is provided with flow monitor in the rear side pipeline of the valve body, being externally coated with for the valve body and valve seat is corrosion-resistant
Coating.
Compared with prior art, the beneficial effects of the invention are as follows：
This multi-functional check valve uses spring type multi-function check valve, simple in structure, during installation only need to by body top and
Multi-functional check valve is fixed on the flange of oil pipe and hydraulic machinery by the flange of bottom, easy to operate, is avoided in the past cumbersome
Fixed form, and inside multi-functional check valve by spring come realize opening and closing, its is simple in structure, and cost is relatively low.
Brief description of the drawings
Fig. 1 is the cross-sectional view of the multi-functional check valve of the present invention.
Wherein：Valve body 1, valve seat 2, oil circuit through hole 2.1, spring base 3, spring pocket 4, spring 5, bolt 6, locking nut 7, method
Orchid 8.
Embodiment
Referring to Fig. 1, the present invention relates to a kind of multi-functional check valve, including valve body 1, the inside of valve body 1 is fixed with valve seat 2, valve seat 2
On be provided with oil circuit through hole 2.1, the valve seat 3 is equipped with spring base 3, and the bottom of the spring base 3 covers oil circuit through hole 2.1, bullet
The top of spring abutment 3 is equipped with spring pocket 4, and spring 5, the valve seat 2,3 and of spring base are equipped between the spring base 3 and spring pocket 4
Spring pocket 4 is by bolt 6 from below to up through mutually fixing, and the top of bolt 6 is equipped with locking nut 7, and locking nut 7 is used for will
Bolt 6 is fixed, and the bottom and top of the valve body 1 are respectively and fixedly provided with flange 8, and the flange 8 is used to fix on multi-functional check valve
On the flange of oil pipe and hydraulic machinery, alarm is provided with the front side pipeline of the valve body 1, can monitor to be passed through unidirectional
The uninterrupted of valve, if by can then alarm higher or lower than standard after being compared with normal discharge, the valve body 1
Rear side pipeline in be provided with flow monitor, the uninterrupted after check valve can be monitored, by being carried out with normal discharge
The valve degree of check valve can be adjusted after comparison, the valve body 1 and valve seat 2 are externally coated with corrosion-resistant finishes, can be with
Prevent check valve from corroding, improve its service life.
When multi-functional check valve leads to oil, oil enters from multi-functional check valve bottom, and passes through the oil circuit through hole 2.1 of valve seat 2,
By spring base 3 it is open-top after just can lead to oil.After logical oil, spring 5 resets spring base 3, spring base 3 is covered oil circuit through hole
2.1.During the installation of multi-functional check valve only need to by body top and the flange of bottom 8 by multi-functional check valve be fixed on oil pipe and
On the flange of hydraulic machinery, installation can be readily achieved, saves the time.
