High Wen Zhusai governing valve

Technical Field

The application relates to the field of valves, in particular to a high Wen Zhusai regulating valve.

Background

In a large wind tunnel test or a large water flow test, a plunger regulating valve is usually used, a piston in a small plunger regulating valve normally moves vertically to stop medium circulation, but with the increase of volume, the pressure of medium circulation is increased, and the pressure to be overcome when the piston moves vertically is increased, so that the opening and closing difficulty is increased, and the piston in the large plunger regulating valve normally moves transversely.

However, the medium flowing in the large-sized plunger regulating valve is large in volume and large in mass, when the piston moves, the friction force between the piston and the inner wall of the valve body is large, so that the friction loss is large, if the inner wall of the valve body and the outer wall of the piston are both made of wear-resistant materials, the cost is increased, and the piston is worn for a long time, and once the piston or the inner wall of the valve body is worn, the sealing performance of the piston is greatly reduced.

Disclosure of Invention

In order to solve the problem that the sealing performance is reduced due to abrasion between the piston and the inner wall of the valve body during sliding, the application provides a high Wen Zhusai regulating valve.

The application provides a high Wen Zhusai regulating valve, which adopts the following technical scheme:

the utility model provides a high Wen Zhusai governing valve, includes the valve body, the export that is used for out the medium and the import that is used for advancing the medium are offered at the both ends of valve body, be provided with in the valve body be used for with the export with the spaced water conservancy diversion body of import, run through on the water conservancy diversion body and offered and open the closed mouth, it is used for control to slide on the water conservancy diversion body the piston that the mouth opened and close is provided with on the valve body, be provided with on the valve body and be used for control the gliding control mechanism of piston, be provided with the sealing ring on the water conservancy diversion body, the sealing ring centers on outside the opening surface of opening and close the mouth, sealing ring outer lane lateral wall is followed the direction of opening and close the mouth extends, be provided with the conflict ring on the piston, be used for contradicting on the sealing ring outer lane lateral wall with sealed clamping ring is provided with on the import inner wall, the piston is followed the direction that the conflict ring is close to or keep away from the sealing ring lateral wall.

Through adopting above-mentioned technical scheme, contradict on the sealing ring lateral wall through the conflict ring, the cooperation piston tip is contradicted and is realized sealedly on the clamping ring, the inner wall that will open and close the mouth through the sealing ring becomes mutually to extend, the rethread is contradicted on the outer lane lateral wall of sealing ring, and not directly block up the sealing ring opening face, the friction of piston when sliding will opening and close mouthful opening closure has been reduced greatly, make the piston lateral wall need not with opening and close mouthful opening face seal with opening and closing peripheral valve body inner wall continuous friction slip, it seals to will opening and close mouthful opening to have reduced the piston, need to close mouthful opening peripheral valve body inner wall friction slip to will open and close mouthful opening seal, lead to piston lateral wall wearing and tearing probability, make the piston not contact with the valve body inner wall when sliding, only at the moment that the piston will open and close mouthful opening seal, the conflict ring, the piston just contacts with sealing ring, the clamping ring laminating, greatly reduced wearing and tearing, life has been prolonged, and sealed intensity is relevant with the piston conflict dynamics, make the staff can adjust suitable seal intensity.

Optionally, the annular has been seted up on the piston lateral wall, it has the trigger sliding ring to slide in the annular, the tip of trigger sliding ring is contradicted on the clamping ring, be provided with in the annular and be used for promoting the trigger sliding ring is contradicted trigger elastic component on the clamping ring, trigger sliding ring tip is the slope setting, the slope trigger sliding ring tip is used for being away from the direction slip of clamping ring under the impact of opening and close mouthful medium circulation.

Through adopting above-mentioned technical scheme, when the piston just slides and opens, just produce the clearance between piston and the clamping ring, because the import and the exit space that open and close the mouth both sides under the confined state exist pressure differential this moment, can produce the medium gushing of the bigger medium velocity of flow under the normal condition when just opening and communicating, the medium is strikeed on the trigger sliding ring, along with the guide entering import of the trigger sliding ring of slope, the gliding trigger sliding ring can cushion the impact that the trigger sliding ring received with triggering the elastic component simultaneously, thereby the impact of medium to the valve body inner wall has been reduced, the probability that tremble appears to the spare part in the valve body has been reduced, the guard action has been played to the valve body, also make the more stable of valve body work, and stability has been improved.
