Abstract
The invention relates to a through-type check valve of a fire resistant oil vacuum filter. The through-type check valve of the fire resistant oil vacuum filter comprises a valve body and a valve element. The valve body is provided with an inlet and an outlet. An inner cavity of the valve element is provided with a conical ceramic sealing cone. A spring is arranged between the conical ceramic sealing cone and the valve body. The conical ceramic sealing cone is fastened at the inlet of the check valve through thrust of the spring and forms sealing. The sealing face, making contact with the conical ceramic sealing cone, of the valve body is also made of ceramic. Inner threads are arranged at the inlet and the outlet of the valve body. The valve body is connected with a fire resistant oil pipeline through the inner threads. The through-type check valve of the fire resistant oil vacuum filter is compact in structure; the manufacturing process is simplified and the manufacturing cost is reduced; installation and use are more convenient; reliability is improved; the service life is prolonged.
Description
Technical field
The present invention relates to one-way valve, specifically a kind of straight check valve of fire-resistant oil vacuum oil-filter.
Background technique
One-way valve is widely used in various oil filter with its characteristic, but existing fire-resistant oil one-way valve exists when cracking pressure greatly, easily produces leakage, valve core movement and has vibration, imbalance, and manufacture and install all comparatively complicated, cost is higher, and working life is shorter, reliability is not ideal enough.
Summary of the invention
The object of this invention is to provide a kind of compact structure, manufacture, easy for installation, working life, longer fire-resistant oil directly can formula one-way valve.
The object of the invention is by realize by the following technical solutions:
The straight check valve of fire-resistant oil vacuum oil-filter, comprise valve body and spool, valve body is provided with import and outlet, described valve core cavity is provided with the conical sealing cone of pottery, be provided with spring between the conical sealing cone of pottery and valve body, the conical sealing cone of described pottery is pressed on the inlet of one-way valve by the thrust of spring and forms sealing.
As the preferred technical solution of the present invention, the sealing surface that described valve body and pottery taper shape seal tapered joint tactile is also be made up of pottery.
As the preferred technical solution of the present invention, described valve body import and outlet port are respectively arranged with internal thread, and valve body is connected with fire-resistant oil pipeline by internal thread.
The invention has the beneficial effects as follows: relative to prior art, compact structure of the present invention, simplified manufacturing process, cost reduce, and install and use convenient, and reliability improves, and working life extends.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and specific embodiment, the invention will be further described:
Fig. 1 is structural representation of the present invention;
The mark implication of accompanying drawing is as follows:
1, valve body; 2, spool; 3, ceramic circular cone situation sealing cone; 4, spring; A, filler opening; B, oil outlet.
Embodiment
As shown in Figure 1, the straight check valve of fire-resistant oil vacuum oil-filter, comprise valve body 1 and spool 2, valve body 1 is provided with filler opening A and oil outlet B, described spool 2 inner chamber is provided with pottery conical sealing cone 3, be provided with spring between pottery conical sealing cone 3 and valve body 1, described pottery conical sealing cone 3 is pressed on the inlet of one-way valve by the thrust of spring 4 and forms sealing.
In the present embodiment, it is also be made up of pottery that described valve body 1 and pottery taper shape seal the sealing surface that cone 3 contacts; Valve body 1 import and outlet port are respectively arranged with internal thread, and valve body 1 is connected with fire-resistant oil pipeline by internal thread.
In work, when fire-resistant oil fluid flows into from filler opening A, oil liquid pressure against the force of the spring and the frictional force between valve body 1 and spool 2, back down the spool with ceramic awl end, flows out from oil outlet B.When fluid oppositely flows into from B, oil liquid pressure makes spool closely be pressed on valve seat, therefore can not adverse current.Because spring only plays reset role, thus spring force is very little.So forward cracking pressure only needs 0.03 ~ 0.05MPa; During reverse cut-off, because spool and valve seat orifice are linear sealing, and sealing force increases with pressure and increases, therefore favorable sealing property.
Claims (3)
