Abstract
The utility model discloses a multifunctional check valve. The check valve comprises a cylindrical valve body. A cylindrical valve body cavity is formed inside the valve body. A flow-in port is formed in one end of the valve body, and a guide plate is arranged at the other end of the valve body. The multifunctional check valve is characterized in that a sealing plate and a movable rod are arranged in the valve body cavity, a flow-out port and a guide hole are formed in the guide plate, and the guide hole is matched with the movable rod; a reset spring which is always in a compressed state is arranged on the periphery of the movable rod between the sealing plate and the guide plate and forces the sealing plate to press the flow-in port. According to the check valve, when liquid comes from the outer side of the sealing plate, the flow-in port can be opened, and the check valve is in an open state; when liquid comes from the outer side of the guide plate, the sealing plate can be forced to press the flow-in port, and the check valve is in a sealing state. The whole check valve can be arranged in a pipeline and prevented from being exposed to outside air, the problem that an existing check valve is easy to corrode is solved, and the service life of the check valve is prolonged.
Description
Technical field
The utility model relates to a kind of Multifunctional single pass valve, in particular, relates in particular to a kind of Multifunctional single pass valve being arranged among pipeline internal cavities.
Background technique
The one-way valve using on oil filed pipeline plays the effect of controlling liquid one-way flowing, existing one-way valve is generally all arranged between the interface of pipeline, in the process of using, be exposed among ambient atmosphere, long-time use can cause one-way valve to be corroded, shorten the working life of one-way valve, affected the normal manufacturing operation in oil field.
Summary of the invention
The utility model is in order to overcome the shortcoming of above-mentioned technical problem, and a kind of Multifunctional single pass valve being arranged among pipeline internal cavities is provided.
Multifunctional single pass valve of the present utility model, comprises cylinder shape valve, and the inside of valve body is cylinder shape valve cavity, and one end of described valve body is provided with inflow entrance, and the other end of valve body is provided with guide plate; Its specialization is: the motion bar that is provided with sealing plate in described valve cavity and fixes with sealing plate, the pilot hole that offers outflow opening on described guide plate and match with motion bar; The periphery of the motion bar between sealing plate and guide plate is provided with the return spring in confined state all the time, and return spring forces sealing plate to press to inflow entrance.
Valve body adopts cylindrical, is conducive to be positioned over the inside of petroleum pipeline.The two ends of valve cavity can communicate with the external world by inflow entrance and outflow opening respectively.One end and the sealing plate of motion bar fix, and the other end is among the pilot hole on guide plate, and pilot hole has guaranteed that motion bar moves along rectilinear direction all the time.At the pressure-acting line of return spring, can force all the time sealing plate to press to inflow entrance, realize seal action.In the process of using, if the pressure of liquid is by guide plate one side in pipeline, fluid pressure can force sealing plate to compress inflow entrance, and now one-way valve is in sealing state; If the pressure of liquid is by sealing plate one side in pipeline, in pipeline under the pressure-acting of liquid, return spring is compressed once again, inflow entrance is opened, liquid in pipeline can be flowed into by inflow entrance, and is flowed out by outflow opening, and now one-way valve is on state.
Multifunctional single pass valve of the present utility model, described guide plate is connected by screw thread with valve body.
Multifunctional single pass valve of the present utility model, the number of the outflow opening of offering on described guide plate is 3.
The beneficial effects of the utility model are: Multifunctional single pass valve of the present utility model, by motion bar, sealing plate and return spring are set in valve cavity, when the pressure of liquid is come by sealing plate outside, further compression retracteding position spring is opened inflow entrance, and one-way valve is in opening state; When the pressure of liquid is come by the outside of guide plate, further force sealing plate to press to inflow entrance, one-way valve is in sealing state.By valve body, be set to cylindrical shape, whole one-way valve can be arranged among pipeline, avoided one-way valve to be exposed among ambient air, solved the problem that existing one-way valve is easily corroded, the working life of the one-way valve of prolongation.

Fig. 3 is the worm's eye view of Multifunctional single pass valve of the present utility model;
Fig. 4 is the sectional view in A-A cross section in Fig. 2.
In figure: 1 valve body, 2 valve cavities, 3 guide plates, 4 outflow openings, 5 inflow entrances, 6 sealing plates, 7 motion bars, 8 return springs, 9 pilot holes.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
As shown in Figure 1, Figure 2 and Figure 3, plan view, the top and bottom perspective views of Multifunctional single pass valve of the present utility model have been provided respectively, Fig. 4 has provided the sectional view in A-A cross section in Fig. 2, and shown Multifunctional single pass valve comprises valve body 1, guide plate 3, sealing plate 6, motion bar 7 and return spring 8; Shown valve body 1 is cylindrical shape, so that be placed among the internal cavities of pipeline.The inside of valve body 1 is columniform valve cavity 2, is provided with inflow entrance 5 on the lower surface of valve body 1; In the situation that sealing plate 6 is not set, valve cavity 2 communicates with the external world by inflow entrance 5.
This one-way valve is directly arranged in pipeline (can be used as bottom valve, also can use as one-way valve) and is used as bottom valve, when equipment operation, owing to forming vacuum in pump case, under atmospheric pressure effect, liquid enters in valve cavity 2 through sealing plate 6, and the outflow opening 4 on guide plate 3 flows out.During as one-way valve: liquid enters in valve cavity 2 through inflow entrance 5 at pump discharge pressure effect lower body, through outflow opening 4, flow out.This apparatus structure is simple, practical.
Multifunctional single pass valve of the present utility model, by motion bar, sealing plate and return spring are set in valve cavity, when the pressure of liquid is come by sealing plate outside, further compression retracteding position spring is opened inflow entrance, and one-way valve is in opening state; When the pressure of liquid is come by the outside of guide plate, further force sealing plate to press to inflow entrance, one-way valve is in sealing state.By valve body, be set to cylindrical shape, whole one-way valve can be arranged among pipeline, avoided one-way valve to be exposed among ambient air, solved the problem that existing one-way valve is easily corroded, the working life of the one-way valve of prolongation.
