Description
Technical Field
The utility model relates to a ball valve, in particular to three eccentric high pressure wear-resisting ball valves of full latus rectum of tube-shape belong to ball valve technical field.
Background
The ball valve is widely applied to devices in the industries of petroleum, petrifaction, metallurgy, power generation and paper making, is a control element in a fluid system, can meet the cutting requirements of various common and severe fluids, and has a leakage grade reaching CLASS VI. In the working state, the common ball valve sealing pair structure has the advantages that because the medium contains complex medium working conditions such as particles, powder, viscous liquid and slurry, the opening and closing torque is large in the opening and closing processes of the valve, the ball body always rubs with the valve seat sealing pair, the sealing pair is easy to wear, and the sealing performance and the service life of the valve are influenced.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to overcome prior art's defect, provide a three eccentric high pressure wear-resisting ball valves of full latus rectum of tube-shape.
In order to solve the technical problem, the utility model provides a following technical scheme:
the utility model relates to a three eccentric high pressure wear-resisting ball valves of full latus rectum of tube-shape, including support frame, barrel, valve rod, the sealed face of spheroid, screw, clamp plate, sealed pad, compound disk seat, clamping ring and valve body, valve body internally mounted has the sealed face of spheroid, the barrel is installed to sealed face one side of spheroid, the barrel is connected on the support frame, connect through the clamp plate between support frame and the sealed face of spheroid, compound disk seat is installed to the junction that both sides are located and the sealed face of spheroid in the valve body, it is fixed with the valve body that compound disk seat passes through the clamping ring, install the valve.
Preferably, the pressure plate is fixed to the valve body by two screws.
Preferably, the valve rod is rotatably connected with the valve body through a support frame.
Preferably, the centers of the inner diameters of the cylinder and the valve body are located at the same point.
Preferably, the cylinder and the valve body have the same inner diameter and length.
The utility model discloses the beneficial effect who reaches is: the utility model discloses it is little to have the moment of torsion of opening and close, the runner is accomplished unblocked when opening entirely, the flow resistance coefficient is little, but the energy saving, the disk seat adopts multiple composite seal substructure reliably, elastic compensation performance has, sealing performance is reliable, when the valve is opened, the spheroid sealed face breaks away from at once with the disk seat sealed face, effectively solve the ordinary structure ball valve and open and close the in-process and be in friction state all the time, after sealed pair wearing and tearing, accessible adjustment drive arrangement, with compensation wearing and tearing, thereby the life of extension valve, the spheroid sealed face hides the inner chamber at the valve body after opening, do not directly erode by the medium, the spheroid sealed face adopts cutting edge-shaped structural design, can the sealed dirt on face of self-cleaning disk seat, structural length is the same with ordinary ball valve structural length, be convenient for replace and maintain.

Detailed Description
The following description will further describe embodiments of the present invention with reference to the accompanying drawings and examples. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
As shown in fig. 1-3, the utility model provides a three eccentric high pressure wear-resisting ball valves of full latus rectum of tube-shape, including support frame 1, barrel 2, valve rod 3, the sealed face 4 of spheroid, screw 5, clamp plate 6, sealed pad 7, compound disk seat 8, clamping ring 9 and valve body 10, 10 internally mounted of valve body has the sealed face 4 of spheroid, barrel 2 is installed to 4 one sides of the sealed face of spheroid, barrel 2 connects on support frame 1, connect through clamp plate 6 between support frame 1 and the sealed face 4 of spheroid, compound disk seat 8 is installed to the junction that both sides are located and the sealed face 4 of spheroid in the valve body 10, compound disk seat 8 passes through clamping ring 9 and fixes with valve body 10, install valve rod 3.
Further, the pressure plate 6 is fixed on the valve body 10 through two screws 5, so that the connection is more compact.
Further, the valve rod 3 is rotatably connected with the valve body 10 through the support frame 1, so that the valve is convenient to close and seal.
Furthermore, the circle centers of the inner diameters of the cylinder body 2 and the valve body 10 are located at the same point, so that the purpose of controlling the fluid is achieved.
Furthermore, the cylinder 2 and the valve body 10 have the same inner diameter and length, so that the fluid is more conveniently controlled.
Specifically, the utility model discloses a fix spheroid sealing ring 4 on support frame 1 through clamp plate 6, barrel 2 is connected on support frame 1, and spheroid sealing ring 4, barrel 2 constitute a holistic spheroid part after being connected fixedly with support frame 1. The composite valve seat 8 is fixed on the valve body 10 through the compression ring 9, and when the valve rod 3 drives the ball body part to rotate clockwise, the valve is closed and sealed. The valve is turned to 90 degrees from the closing state anticlockwise, the valve is completely opened, the inner diameter of the cylinder body 2 is concentric with the channel of the valve body 10, and the diameter of the channel is equal to that of the channel, so that the aim of controlling the fluid is fulfilled.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the technical principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
