Abstract
The utility model relates to a mesh cohesive-type control valve of a control valve, which is applicable to a pressure piping system in need of safely reducing or accurately regulating the flow of the projects such as running water, water diversion, hydropower station and circulating water. A driving device is arranged at one side of the valve and is connected with a valve shaft, a rubber sealing ring is arranged on a valve body, a telescopic cylinder is arranged in the valve body and is connected with the valve shaft through a crank linkage, and a mesh body cylinder with an increasing mesh is arranged in the valve body. A runner adopts the geometric streamline design and can control a medium runner to change in a certain range so as to effectively prevent the cavitation from damaging the valve body and lead the valve to maintain the stable running effect and the antivibration performance under the condition of large pressure change. The valve has small volume, low manufacturing cost and small installing space.
Description
Technical field
The utility model relates to modulating valve.
Background technique
Be applicable to the modulating valve that needs safety to reduce pressure and accurately regulate the pressure pipeline system of flow, be provided with a fusiformis body tube in its valve body, when medium flows into valve body, respectively from the runner outflow on the both sides of valve body and fusiformis body tube.Owing to reducing pressure and regulating in the process of flow, medium to valve body after the impact force of tube wall bigger, vibrate also big, as easy as rolling off a log to pipe-line system generation cavitation damage.Simultaneously, be difficult to guarantee the effect of operation, and the life-span of valve is short.
Summary of the invention
The purpose of this utility model is to provide poly-formula modulating valve in a kind of mesh, and it is a kind of mesh body sleeve that a mesh increases gradually that is provided with in valve body, can reduce medium to valve body after the impact force of tube wall, prevent the valve of cavitation damage.
The technical solution of the utility model is:
The utility model comprises valve body, valve shaft, retracting cylinder, connecting rod, seal ring, drive unit, drive unit is connected on the valve body and with valve shaft and is connected, retracting cylinder is connected in the valve body and by connecting rod and is connected with valve shaft, seal ring is connected with the mesh body tube that a mesh increases gradually in the described valve body on valve body.
Advantage of the present utility model is as follows:
1, is how much airflow designs in the medium runner of the present utility model, when MEDIA FLOW during through valve body, can prevent cavitation damage effectively, make valve under the bigger situation of variation in pressure, keep stable operational effect and good dynamic vibration proof performance, guarantee the linearly adjust feature of valve.Also be a kind of process of self-energy dissipating simultaneously.
2, the connecting rod of the utility model inside moves the axial footpath that rotatablely moving of live axle changes into retracting cylinder, the inside water pressure of retracting cylinder and external water pressure energy self balance, and valve operation is light, stable, reliable.
3, structure length of the present utility model is short, and boundary dimension is little, and the occupation of land space is little, and simple installation can be saved engineering investment cost.
Description of drawings
Fig. 1 is the utility model outline drawing;
Fig. 2 is a structural representation of the present utility model;
Fig. 3 is the enlarged view of I.
Embodiment
Referring to Fig. 1～3, embodiment of the present utility model is further described.
Because medium runner of the present utility model is how much airflow designs, by converging to the pipeline axle center after the 7 annular poroid throttlings of mesh body tube.In the valve opening starting stage, mesh body tube 7 front and back pressure reduction are bigger, and less because of the mesh of mesh body tube 7 fronts, the rate-of flow of flowing through is little, reduced the impact of valve body 5 back tube walls, along with the unlatching of valve, mesh body tube 7 front and back pressure reduction reduce, because the mesh on the mesh body tube 7 becomes big gradually, the rate-of flow of flowing through increases gradually, can change within the specific limits by the control media flow velocity,, prevent cavitation damage effectively and have good dynamic vibrationproof performance to reduce impact to tube wall behind the valve body.
