Abstract
A conical guide high-pressure check valve. The main problem of solving current check valve sealing performance poor, unable sealed when transversely using. The method is characterized in that: the middle of the inner wall of the upper connector (1) is provided with a step, the lower part of the step is provided with a valve seat (2), the bottom of the inner wall of the valve seat (2) is matched with a conical valve core (3), the bottom of the valve core (3) is provided with a spring (5), the bottom of the spring (5) is propped against a valve core support (6), and the valve core support (6) is placed on the step of the lower connector (8). The conical guide high-pressure check valve can bear higher pressure and is good in sealing effect.
Description
Technical Field
The utility model relates to an oil field, specific toper direction high pressure single current valve that says so.
Background
The check valve is a common tool on the ground or in the well in the oil field production, most of the check valves used in the oil field at present are in a plane sealing mode, and although the check valve can bear higher pressure, the sealing performance is not ideal, and the check valve can hardly seal when being used transversely on the ground, so that the existing check valve needs to be further improved.
Disclosure of Invention
In order to overcome the not enough that current check valve sealing performance is poor, can't seal when transversely using, the utility model provides a toper direction high pressure check valve, this toper direction high pressure check valve can bear higher pressure, and is sealed effectual.
The technical scheme of the utility model is that: the conical guide high-pressure check valve comprises an upper joint, wherein the bottom of the upper joint is in threaded connection with a lower joint, a step is arranged in the middle of the inner wall of the upper joint, a valve seat is arranged on the lower portion of the step, the bottom of the inner wall of the valve seat is matched with a conical valve core, a spring is arranged at the bottom of the valve core, the bottom of the spring abuts against a valve core support, and the valve core support is placed on the step of the lower joint.
The bottom of the valve seat is provided with a guide sleeve, and the bottom of the guide sleeve is propped against a step in the middle of the lower joint.
The valve core is characterized in that a valve rod is connected to the bottom of the valve core, a spring is sleeved outside the valve rod, the valve rod penetrates through a center hole of the valve core support, and a nut is connected to the bottom of the valve rod.
The utility model discloses following beneficial effect has: due to the adoption of the scheme, the check valve adopts the conical valve core to be matched with the valve seat, and the spring is arranged between the bottom of the valve core and the valve core support, so that the valve core can bear higher pressure, can be reset quickly, and has a good sealing effect. The check valve can be applied to underground, and can also be applied to horizontal or longitudinal pipelines on the ground, and the application range is wide.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure, 1-an upper connector, 2-a valve seat, 3-a valve core, 4-a guide sleeve, 5-a spring, 6-a valve core bracket, 7-a nut and 8-a lower connector.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings:
shown by figure 1, a toper direction high pressure single current valve, including top connection 1, top connection 1 bottom threaded connection lower clutch 8, top connection 1 inner wall middle part is equipped with the step, and the step lower part is equipped with disk seat 2, and is equipped with the sealing washer between disk seat 2 outer wall and top connection 1. The bottom of the valve seat 2 is provided with a guide sleeve 4, the bottom of the guide sleeve 4 is propped against the step in the middle of the lower joint 8, and the valve seat 2 is fixed on the upper joint 1 by the guide sleeve 4. Two steps are arranged in the middle of the lower joint 8, wherein the guide sleeve 4 is propped under the step at the upper part, and the valve core support 6 is arranged on the step at the lower part. The bottom of the inner wall of the valve seat 2 is matched with the valve core 3, and the upper part of the valve core 3 is conical and is sealed with the valve seat 2 through a conical surface. The bottom of the valve core 3 is connected with a valve rod, a spring 5 is sleeved outside the valve rod, the bottom of the spring 5 is propped against the valve core support 6, the valve rod penetrates through a center hole of the valve core support 6, and the bottom of the valve rod is connected with a nut 7. And a plurality of liquid passing holes are also processed on the valve core bracket 6.
The conical guide high-pressure check valve can be put into a well along with a pipe column and also can be connected to a ground pipeline, when liquid flows through inner holes of the upper connector 1 and the valve seat 2, the valve core 3 is pushed to move downwards under the action of pressure, and meanwhile, the compression spring 5 opens a liquid flow channel, so that the liquid smoothly passes through the conical guide high-pressure check valve; when stopping suppressing, under the effect of spring 5 to and under the guide of uide bushing 4 and 3 toper tops of case, case 3 resets fast, closes the passageway, has played the single current effect, has had the toper structure of case 3 simultaneously, makes this single current valve can bear higher pressure.
