The first scraper blade and the second scraper blade automatically clear crystallization media on the surface of the ball core and the inner wall of the valve body in the opening and closing process of the ball core, so that the sealing surface of the sealing element is protected, the ball core is prevented from being jammed or locked, the production is not stopped, and the long-period normal operation is realized.
Description
Technical Field
The invention relates to the technical field of valves, in particular to a rotary ball core descaling mechanism for a ball valve.
Background
The ball valve is widely applied to industries such as petroleum refining, long-distance pipelines, chemical industry, papermaking, pharmacy, water conservancy, electric power, municipal administration, steel and the like, and plays a significant role in national economy. Ball valves are used in pipelines primarily to shut off, distribute or change the flow direction of a medium, enabling a tight shut-off.
When the ball valve is used in the working conditions that the medium has high viscosity and is easy to crystallize or scale, as shown in fig. 4, in the opening and closing process of the ball core, the valve body inlet, the ball core inlet and the valve cavity are communicated, and part of the medium enters the valve cavity between the ball core inlet and the valve body; when the ball core is closed, the medium is easy to adhere to the surface of the ball core and the inner wall of the valve body; long-time accumulation not only can influence the sealing performance of ball core, still can cause the damage to the sealing member surface opening and close the in-process, and the switching moment of torsion of increase ball valve simultaneously leads to the valve bite, locks the scheduling problem, seriously influences normal production, and the only solution is that the valve that the dismantlement broke down carries out the outside washing, causes the parking to subtract the output.
Disclosure of Invention
The technical problem to be solved by the invention is as follows: the ball valve solves the technical problems that when the traditional ball valve is used in the working condition that the medium viscosity is high, crystallization or scaling is easy to happen, the performance is easy to reduce, and the production efficiency is influenced.
The invention provides a rotary type ball core descaling mechanism which is arranged in a valve body and comprises a ball core, wherein a first scraper and a second scraper are arranged in the valve body, the first scraper scrapes crystalline media on the inner wall of the valve body in the opening and closing process of the ball core, and the second scraper scrapes the crystalline media on the surface of the ball core.
In the opening and closing process of the ball core, the first scraper plate automatically scrapes off the crystalline medium on the inner wall of the valve body, and the second scraper plate automatically clears away the crystalline medium on the surface of the ball core, so that the sealing surface of the sealing element is protected, the jamming or locking of the ball core is prevented, the shutdown is not performed, the production is not reduced, and the long-period normal operation is realized.
Furthermore, the first scraper blade is fixedly connected with the ball core, and the second scraper blade is fixedly connected with the valve body. The second scraper is in a fixed state, and crystal media on the surface of the ball core are scraped by the rotation of the ball core; the first scraper plate rotates along with the ball core, and crystal media on the inner wall of the valve body are scraped through the rotation of the ball core.
Furthermore, the first scraper is arc-shaped, and a gap is formed between the first scraper and the inner wall of the valve body; the second scraper blade is arc-shaped, and a gap is formed between the second scraper blade and the ball core. So set up, avoid ball core surface and valve body inner wall impaired.
Furthermore, the convex surface of the first scraper is provided with a plurality of first grooves, and the concave surface of the second scraper is provided with a plurality of second grooves. The medium scraped by the first scraper plate enters the valve cavity through the first groove, and the medium scraped by the second scraper plate enters the valve cavity through the second groove and enters the downstream pipeline under the impact action of the medium pressure, so that the sealing surface of the ball core and the valve cavity are cleaned.
Furthermore, when the ball core is opened, the first scraper and the second scraper point to the inlet of the ball core and form an angle of 45 degrees with the flow channel of the ball core. So set up, the ball core only needs the process of once opening or closing, just can accomplish the clearance of ball core surface and valve body inner wall to clean efficiency has been improved.

FIG. 2 is a top view of the open position of the core;
FIG. 3 is a top view of the core in a closed position;
FIG. 4 is a state diagram of the opening and closing process of the ball core;
in the figure: 1. a ball core; 2. a first squeegee; 3. a second squeegee; 21. a first groove; 31. a second groove.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic views illustrating only the basic structure of the present invention in a schematic manner, and thus show only the constitution related to the present invention.
As shown in fig. 1, the invention is a rotary ball core descaling mechanism, which is arranged in a valve body and comprises a ball core 1, wherein a first scraper 2 is arranged at the inlet end of the ball core 1, the first scraper 2 is arc-shaped and is in clearance fit with the inner wall of the valve body for preventing the inner wall of the valve body from being damaged, and a plurality of first grooves 21 are uniformly distributed on the convex surface of the first scraper 2; two ends of the rotating shaft of the ball core 1 are provided with fixed plates, and a second scraper 3 is arranged on the two fixed plates; the second scraper blade 3 is located 1 entrance of core and with 1 clearance fit of core for prevent that 1 surface of core from damaging, the second recess 31 of a plurality of equipartitions still is equipped with to the 3 concave surfaces of second scraper blade.
As shown in fig. 2, when the ball core 1 is in an open state, the first scraper 2 and the second scraper 3 both point to the inlet of the ball core 1 and both form an angle of 45 degrees with the flow channel of the ball core 1; so set up, the process that only needs once to open or close of ball core 1 just can accomplish the clearance of 1 surface of ball core and valve body inner wall to clean efficiency has been improved.
As shown in fig. 2 and fig. 3, in the process of opening and closing the ball core 1 at 90 °, the first scraper 2 scrapes off the crystallized medium on the inner wall of the valve body, and the scraped medium enters the valve cavity through the first groove 21; the second scraper 3 scrapes off the crystalline medium on the surface of the ball core 1, and the scraped medium enters the valve cavity through the second groove 31; and enters a downstream pipeline under the impact action of medium pressure, so that the sealing surface and the valve cavity of the ball core 1 are cleaned; thereby realize the automatic clearance of ball core 1 surface and valve body inner wall, the sealed face of protection sealing member prevents that ball core 1 from blocking puckery or locking, does not have the stop, does not reduce production, realizes long period normal operating.
In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations will be apparent to those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
