Abstract
The utility model provides a hydraulic pressure system one way valve which comprises a valve body. The valve body is provided with a valve core. An upper end and a lower end of the valve body are respectively connected with an upper valve cover and a lower valve cover. The valve body is sealed by the upper valve cover and the lower valve cover. The upper valve cover and the lower valve cover are provided with water inlet channels and water outlet channels. A spring is arranged between the valve core and the upper valve cover. The lower end of the valve core takes a tapered structure. The lower valve cover is provided with a valve core case which is matched with the tapered structure. The valve core is also provided with a through-flow hole which runs through an inner cavity of the valve body. A water inlet on the lower end of the through-flow hole is positioned above the matching position of the valve core and the valve core case. The hydraulic pressure system one way valve has low cost, simple and compact structure, reliable operation, no leakage and long service life, and can have wide application in the design and manufacture of the hydraulic pressure system.
Description
Technical field
The utility model relates to a kind of water valve.
Background technique
After the eighties in 20th century, because the appearance of environmental protection requirement and oil crisis, the hydraulic drives technology has caused people's attention.One-way valve is the important valve member of hydraulic pressure system; with compare as the hydrovalve of working medium with oil; directly with natural sea-water or fresh water as the water hydraulic drive technology of hydraulic medium have safety, with characteristics such as environmentally compatible, energy-conservation, economy, health; can satisfy people to greatest extent for the craving for of aspects such as safety, energy economy ﹠ environment protection, meet the needs of human kind sustainable development.Therefore, the hydraulic drives technology has become the advanced subject in current international hydraulics field, has extremely wide application prospect.But water is compared with mineral type hydraulic oil as hydraulic transmission medium, and characteristics such as have poor lubricity, corrosivity is big, and viscosity is low have all had new requirement to product structure, selection, technology, sealing.
Summary of the invention
Technical problem to be solved in the utility model provide a kind of can be directly with natural sea-water or fresh water hydraulic pressure system one-way valve as working medium.Therefore, the utility model is by the following technical solutions: it comprises valve body, be provided with spool in the described valve body, the two ends up and down of described valve body connect bonnet and bottom flange respectively, all sealings between valve body and bonnet, valve body and the bottom flange, bonnet and bottom flange are provided with the discrepancy water channel, be provided with spring between spool and the bonnet, the spool lower end is a cone structure, bottom flange is provided with the valve core case that matches with this cone structure, spool also is provided with and connects body cavity through flow hole up and down, and the water intake of through flow hole lower end is positioned at the top of spool and valve core case cooperation place.
By above technological scheme, the utility model cost is low, simple and compact for structure, reliable operation, nothing are leaked, long service life, can be widely used in the design of hydraulic pressure system with in making.
Description of drawings
Fig. 1 is the utility model embodiment 1 a longitudinal sectional view.
Embodiment
With reference to accompanying drawing, the utility model comprises valve body 3, is provided with spool 4 in the valve body 3, and the two ends up and down of valve body 3 connect bonnet 1 and bottom flange 7 respectively, is provided with seal ring 2 between valve body 3 and the bonnet 1, is provided with seal ring 8 between valve body 3 and the bottom flange 7.
Be provided with the water channel 9 of coming in and going out in bonnet 1 and the bottom flange 7, be provided with spring 5 between spool 4 and the bonnet 1, spring 5 one ends are against bonnet 1 diapire, and the other end supports spool 4.
Spool 4 heads adopt the cone structure 13 of band soft seal in the utility model, with the cone angle design of spool 4 is 60 °, bottom flange 7 is provided with the valve core case 10 that matches with this cone structure, in briny environment, suction valve uses taper valve core can prevent the stuck and obstruction that causes because of marine organisms and microorganism well.Because sealing surface is taper, has certain leading role, can guarantee the accuracy that spool 4 moves up and down, and also has certain self-align compensate function simultaneously.
Adopt soft seal between spool 4 and the bottom flange 7, promptly also be provided with soft seal circle 6 between spool 4 and the valve core case 10, can well guarantee airtight performance.In addition, the coaxality ratio between the conical surface of spool 4 (sealing surface) and cylndrical surface (guide surface) is easier to guarantee.Have on the spool 4 and connect body cavity through flow hole or groove 11 up and down, the water intake 12 of through flow hole or groove 11 lower ends is positioned at the top of spool and valve core case cooperation place.
Spool 4 adopts rigid, lightweight non-metallic material in the utility model, such as engineering plastics, can have better water-fast corrosivity, and in light weight, inertia is little, and noise is little, opens and closes flexibly, both can make suction valve usefulness, also can make delivery valve and use.
To sum up, big, the corrosion resistant of low, simple and compact for structure, the reliable operation of the utility model cost, negotiability, good airproof performance, leakage less, be active in one's movements, antipollution power is strong, energy-conserving and environment-protective, long service life, Maintenance and Repair are convenient.Be applicable to high pressure, big flow hydraulic pressure system, can be widely used in the design of hydraulic pressure system with in making.
At last, it is also to be noted that, more than only be examples of implementation of the present utility model.Obviously, enforcement of the present utility model is not limited to above embodiment, and many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should be thought protection domain of the present utility model.
