Specific embodiment
As shown in Figure 1 to Figure 3, a kind of unidirectional accumulator valve described in the utility model, it is in integrally inverted T shape.It is described unidirectional
Accumulator valve, including valve body 1 and the bonnet 2 being installed on valve body 1.Left side is offered into liquid/gas passage 11 in the valve body 1, right
Side offers out liquid/gas passage 12, and top offers threaded openings.The bonnet 2 coordinates solid with the threaded openings screw thread of valve body 1
The top of valve body 1 is scheduled on, the bonnet 2 is also tightly connected by sealing ring 6 at the threaded openings of valve body 1 with valve body 1.It is described
Cavity 10 is formed between valve body 1 and bonnet 2.The cavity 10 is located at into liquid/gas passage 11 and goes out the upper of liquid/gas passage 12
Portion.
It is described enter liquid/gas passage 11 it is L-shaped, it is described enter liquid/gas passage 11 have stretch into cavity 10 first connection
Mouth 13, first connected entrance 13 is stretched into cavity 10 straight up.It is described go out liquid/gas passage 12 it is also L-shaped, it is described go out
Liquid/gas passage 12 is located at the bottom of cavity 10 with the second connected entrance 14 of the connection of cavity 10.First connected entrance 13 is higher than
Second connected entrance 14.
Piston component and elastic pressure parts 3 are actively provided with the cavity 10, the elastic pressure parts 3 are arranged on the work
Between plug assembly and bonnet 2 and the piston component is promoted to be pressed against on the first connected entrance 13.The piston component includes piston
Key 4 and the piston head 5 being fixedly installed on piston key 4.
In the present embodiment, the elastic pressure parts 3 are compression spring.Guide is provided with the upper inside wall of the cavity 10
7.The upper end of the compression spring is connected with guide 7, and the lower end of the compression spring is fixedly connected with piston key 4,
The compression spring is only capable of upper and lower stretching motion under the guide effect of guide 7.
The piston key 4 is the blocks that ageing-resistant material is made, such as be made of stainless steel.In order to ensure piston head
5 pairs of sealings of the first connected entrance 13, the piston head 5 is made up of flexible glue material, and in the present embodiment, the piston head 5 can be with
It is rubber piston head or silica piston head.The bottom of the piston key 4 offers mounting groove 41, under the piston key 4
End face is plane, and the piston head 5 is embedded in mounting groove 41 and the lower surface of piston head 5 is neat with the lower surface of piston key 4
It is flat.Lower surface of first connected entrance 13 only with piston head 5 contacts, and the lower surface of the piston head 5 can be against the first company
First connected entrance 13 is closed on port 13.
Unidirectional accumulator valve described in the utility model is in normally off when unused.During using unidirectional accumulator valve, from entering
Liquid/gas passage 11 enters liquid/gas.When the liquid gas backpressure for entering liquid/gas passage 11 is not up to the startup pressure of unidirectional accumulator valve
When, the lower surface of piston head 5 is against on the first connected entrance 13 all the time closes the first connected entrance 13, enters liquid/gas passage 11 and goes out
Liquid/gas passage 12 is not turned on.
When the liquid/gas body back pressure for entering liquid/gas passage 11 gradually increases the startup pressure for reaching unidirectional accumulator valve,
Liquid/gas road turns on, and the piston head 5 opened by liquid/gas body top, and liquid/gas body flows into cavity 10 and from liquid/gas passage 12 is gone out
Go out.
When unidirectional accumulator valve stops into liquid/gas, the liquid/gas body back pressure in unidirectional accumulator valve is gradually reduced, and piston head 5 exists
Resilience again closes the first connected entrance 13 in the presence of elastic pressure parts 3, and liquid/gas road closes again, and liquid/gas body is no longer from going out
Liquid/gas passage 12 flows out.
If liquid/gas body from go out liquid/gas passage 12 enter unidirectional accumulator valve when, liquid/gas road all the time be in closure state,
Liquid/gas body cannot flow out from liquid/gas passage 11 is entered, and reach the function of unidirectional cutoff.
It can be seen that, the piston head 5 in unidirectional accumulator valve described in the utility model only has lower surface and is connect with the first connected entrance 13
It is also plane contact when touching and contacting with each other, reduces the exposed area of piston head 5.Unidirectional accumulator valve is set to be used in long-time
In, piston head 5 is sufficiently small with the contact area of fluid, and piston head 5 is non-aging, substantially prolongs the service life of piston head 5.
Meanwhile, the making contact of the connected entrance 13 of piston head 5 and is plane contact, and without sharp parts collision, piston head 5 is not easy to wear.
Other piston key 4 is also adopted by ageing-resistant material and is made, and its service life can also be ensured well.In unidirectional accumulator valve
Component structural it is simple, ageing-resistant, long lifespan, reliable in action, good stability.
As described above, we are illustrated fully according to objective of the present utility model, but the utility model not limits to
In above-described embodiment and implementation.The practitioner of correlative technology field can be in the scope of technological thought of the present utility model license
Inside carry out different changes and implementation.
