Description
Technical Field
The utility model relates to a check valve technical field especially relates to gravity type check valve.
Background
The valve is a control part in a fluid conveying system and has the functions of stopping, adjusting, guiding, preventing counter flow, stabilizing pressure, shunting or overflowing and relieving pressure and the like. The valves used in fluid control systems range from the simplest stop valves to the most complicated valves used in autonomous systems, and are of a wide variety of types and specifications, wherein the check valve is a one-way valve, also known as a check valve, in which fluid can only flow along the water inlet and the medium at the water outlet can not flow back. For use in hydraulic systems to prevent reverse flow of oil flow, or in pneumatic systems to prevent reverse flow of compressed air. The check valve has two types of straight-through type and right-angle type. The straight-through check valve is installed on the pipeline by threaded connection. The right-angle check valve has three forms of threaded connection, plate type connection and flange connection.
The existing check valve needs to be provided with a rocker, a lifting lug, a connecting frame and the like in order to ensure that the valve clack is reset, and has various parts and high failure rate.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a gravity type check valve that leans on valve clack gravity to reset at the end of simple and practical, the fault rate is provided.
The utility model discloses a realize through following technical scheme:
gravity type check valve, including valve body, disk seat, valve clack and pipeline, the valve body is hollow structure, the disk seat sets up in the valve body, the pipeline passes through the disk seat extends to the valve body is outside, the valve clack is disc type structure, the top edge of disk seat with be provided with the roller bearing between the top edge of valve clack, the disk seat with the valve clack passes through the roller bearing is articulated to be connected, the disk seat inlays with tilt up in the valve body, the valve clack lock with tilt up is in on the disk seat.
Further, a gasket is further arranged between the valve seat and the valve clack, the gasket protrudes out of the annular structure of the valve seat, and the gasket is made of polytetrafluoroethylene.
Furthermore, a lifting ring is arranged on the outer wall of the valve body and comprises a screw screwed on the valve body, a groove transversely penetrating through the screw is formed in the middle of the screw, a metal ring capable of freely sliding along the groove is arranged in the groove, and the metal ring is sleeved on the groove.
Beneficial effects of the utility model
The gravity type check valve is characterized in that the valve seat is hinged to the valve clack through a rolling shaft at the upper edge, the valve seat is embedded in the valve body in an upward inclined mode, the valve clack is buckled on the valve seat in an upward inclined mode, reset is achieved by the aid of the gravity of the valve clack, and the gravity type check valve is simple and practical in structure and low in failure rate.
Preferably, the disk seat with still be provided with the packing ring between the valve clack, the packing ring for protrusion in the loop configuration of disk seat, the packing ring is the polytetrafluoroethylene material, and the setting of packing ring has avoided the direct striking between disk seat and the valve clack, and especially polytetrafluoroethylene material itself has inadhesion and self-lubricity, has reduced the fault rate of disk seat and valve clack, has prolonged life.
Preferably, be provided with rings on the outer wall of valve body, rings are including screwing screw on the valve body, the middle part of screw is provided with transversely runs through the groove of screw, the inslot is provided with and follows the groove is free gliding metal loop, the metal loop snare be in on the groove, set up rings and make things convenient for the transport of valve body, use screw makes things convenient for the dismantlement and the change of rings, and the metal loop can be followed the groove is free to slide, has avoided rings too high, influences service environment.
Drawings
FIG. 1 is a front view of the present invention;
FIG. 2 is a schematic view of the three-dimensional structure of the present invention with a part of the valve body cut away;
in the figure, 1 is a valve body, 2 is a valve clack, 3 is a gasket, 4 is a valve seat, 5 is a pipeline, 6 is a rolling shaft, 7 is a lifting ring, 8 is a metal ring, 9 is a screw, and 10 is a groove.
Detailed Description
As shown in fig. 1 and fig. 2, the utility model provides a valve body 1 of gravity type check valve is hollow structure, pipeline 5 extends to the outside of valve body 1 through the disk seat 4 that sets up in valve body 1, valve clack 2 is the disc type structure, the welding has roller bearing 6 between the top edge of disk seat 4 and the top edge of valve clack 2, disk seat 4 passes through roller bearing 6 articulated connection with valve clack 2, disk seat 4 inlays in valve body 1 tilt up, valve clack 2 tilt up lock is on disk seat 4, still bond the packing ring 3 that has the loop configuration of protrusion in disk seat 4 between disk seat 4 and the valve clack 2, packing ring 3 is the polytetrafluoroethylene material, still have rings 7 on the outer wall of valve body 1, rings 7 are provided with the screw 9 of the horizontal groove 10 that runs through including screwing in the middle part on valve body 1, and the ring cover is in groove 10 and can follow groove 10 free gliding metal loop 8.
The working mode is as follows: fluid flows into valve body 1 back from pipeline 5, through disk seat 4 break valve clack 2, when the fluid cutout, valve clack 2 can fall back because of self gravity, because disk seat 4 inlays in valve body 1 tilt up, valve clack 2 lock on disk seat 4 tilt up, so valve clack 2 only can realize the reset function by self gravity, need not set up other spare part help it in addition and reset, and simple structure is practical, at the bottom of the fault rate, the packing ring 3 of bonding polytetrafluoroethylene material on disk seat 4, avoid valve clack 2 direct striking to disk seat 4 when reseing.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
