Abstract
The utility model relates to a novel hydraulic control one-way valve, which comprises a valve body (1), an oil outlet (2) and an oil inlet (3), wherein the oil outlet (2) and the oil inlet (3) are arranged at two sides of the valve body (1), both front ends of the oil outlet (2) and the oil inlet (3) are provided with a groove (2-1), a sealing ring (2-2) is arranged inside the groove (2-1), and both the oil outlet (2) and the oil inlet (3) are provided with an eversion flange (2-3). The novel hydraulic control one-way valve not only maintains the air tightness and reliability of the present hydraulic control one-way valve, but also is convenient to install, is difficult to leak oil, and saves the cost.
Description
Technical field:
The present invention relates to mechanical field, be specifically related to a kind of novel hydraulic-control one-way valve.
Background technique:
Pilot operated check valve is few because of leakage rate, latch performance good, reliable operation is widely used in the metallurgical hydraulic system, as iron works clay gun revolution hydraulic pressure installation, electric furnace electrode lifting loop, electric furnace material basket car suspension hydraulic loop etc., milling train and coiling machine hydraulic system are used Pilot operated check valve especially in a large number, and this valve occupies than consequence in the hydraulic equipment of machinery.It and the common one-way valve difference control oil channel that has been many, when control oil channel access failure pressure oil liquid, Pilot operated check valve is worked as common one-way valve, and pressure oil only flows to oil outlet from filler opening, can not reverse flow.When the input of control oil channel oil pilot pressure, piston mandril moves right under the pressure oil effect, backs down one-way valve with push rod, oil inlet and outlet is connected, if oil outlet just can make the fluid reverse flow greater than filler opening.
Present Pilot operated check valve all adopts entrance point, outlet end by flange and screw and the installation of oil pipe ways of connecting, and this mounting type is very loaded down with trivial details, wastes time and energy; And in flanged surface and the screw hole all oil leakage phenomenon can take place, cause unnecessary waste.
Summary of the invention:
The purpose of this invention is to provide a kind of novel hydraulic-control one-way valve, it not only preserves the closed and the reliability of existing Pilot operated check valve, and easy for installation, and cost is saved in not easy oil leakage.
In order to solve the existing problem of background technique, the present invention is by the following technical solutions: it comprises valve body, oil outlet and filler opening, and oil outlet and filler opening are arranged on the both sides of valve body.
Described oil outlet and filler opening front end are provided with groove, are provided with seal ring in the groove.
Described oil outlet and filler opening are equipped with the flange that turns up.
The present invention not only preserves the closed and the reliability of existing Pilot operated check valve, and easy for installation, and cost is saved in not easy oil leakage.
Description of drawings:
Fig. 1 is a structural representation of the present invention,
Fig. 2 is a mounting structure schematic representation of the present invention.
Embodiment:
With reference to Fig. 1-2, this embodiment by the following technical solutions: it comprises valve body 1, oil outlet 2 and filler opening 3, and oil outlet 2 and filler opening 3 are arranged on the both sides of valve body 1.
Described oil outlet 2 and filler opening 3 front ends are provided with groove 2-1, are provided with seal ring 2-2 among the groove 2-1.
Described oil outlet 2 and filler opening 3 are equipped with the flange 2-3 that turns up.
This embodiment is installed in the inside of oil cylinder 4, and its oil outlet 2 is connected to the outside by bolt and flange with oil pipe, installs very conveniently, and saves the oil pipe consumption, reduces cost; After the installation, seal not easy oil leakage, good airproof performance between the junction surface of valve body 1 and oil pipe by seal ring 2-2.
This embodiment is not only preserved the closed and the reliability of existing Pilot operated check valve, and easy for installation, and cost is saved in not easy oil leakage.
