Abstract
The utility model discloses a check valve. The check valve comprises a valve body with an oil inlet and an oil outlet, wherein a valve base is arranged in the valve body; a valve core is arranged on the valve base; the valve core is connected on the valve base by a valve body and an elastic piece in a pressed manner; and an oil hole which is communicated with the oil outlet of the valve body is arranged on the valve cover. The check valve has a simple design, convenience in maintenance and low maintenance cost.
Description
Technical field
The utility model relates to a kind of one-way valve.
Background technique
Superhard material industry superpressure pump oil outlet place all is equipped with one-way valve at present, plays the effect that prevents that hydraulic oil from refluxing, and its structure is as shown in Figure 1, comprises that there is the valve body 1 of through hole at a center, and the spool 2, spring 3 and the jump ring 4 that have the conical surface are installed in the valve body 1.The conical surface of spool 2 and valve body 1 step contact seal, spring 3 acts on the spool 2, and jump ring 4 plays the effect that prevents that spring 3 from dropping out.Shortcoming is that spool 2 is fragile through the impact of high pressure oil for a long time with valve body 1 sealing part, can't repair after the damage, needs to change a new one-way valve, and waste is serious, increases maintenance cost.
The model utility content
The purpose of the utility model provides a kind of one-way valve of convenient for maintaining.
For achieving the above object, the technological scheme that the utility model adopts is:
A kind of one-way valve comprises the valve body that has oil inlet hole and oil outlet, is provided with valve seat in the valve body, and valve seat is provided with spool, and spool is crimped on the valve seat through valve gap and elastic component, and valve gap is provided with the oilhole that is communicated with the valve body oil outlet.
The valve body oil outlet is arranged on the body wall.
Between said valve seat and the valve body, be equipped with seal ring between end cap and the valve body.
Said valve gap is connected with valve body through bolt.
The utility model is employed in valve seat is set in the valve body, and valve seat is connected this structural design with spool, if one-way valve damages, only needs replacing valve seat or spool to get final product, and easy to maintenance, the valve body long service life reduces maintenance cost.
Description of drawings
Fig. 1 is traditional one-way valve structures schematic representation;
Fig. 2 is the utility model structural representation.
Embodiment
As shown in Figure 2, a kind of one-way valve comprises the valve body 7 that has oil inlet hole 13 and oil outlet 14; Be provided with valve seat 8 in the valve body 7; Valve seat 8 is provided with spool 9, and spool 9 is crimped on the valve seat 8 through valve gap 11 and spring 10, and valve gap 11 is provided with the oilhole 15 that is communicated with valve body oil outlet 14.Valve body oil outlet 14 is arranged on valve body 7 sidewalls.Between said valve seat 8 and the valve body 7, be equipped with seal ring 16 between end cap 11 and the valve body 7.Said valve gap 11 is connected with valve body 7 through bolt 12.
When the utility model uses, excess pressure pump work, hydraulic oil gets into valve body 7 from oil inlet hole 13, and oil pressure is pushed spool 9 open, flows out through oil outlet 14 from oilhole 15; When excess pressure pump quit work, spool 9 resetted under the effect of hydraulic oil and spring 10, and closed check valve prevents that hydraulic oil from refluxing, simplicity of design, and also maintenance cost easy to maintenance is low.
