Problems solved by technology

[0003] Since the sediment at the bottom of the reservoir after the heavy rain is easy to float upwards, the pipeline for transporting the water source of the reservoir is easy to enter the sediment, so that the sediment will pass through the inner wall of the connecting port of the valve body. If the valve is closed at this time, the sealing strip on the valve disc will be easily damaged. Affected by extrusion deformation and wear, if this happens for a long time, the sealing effect of the sealing strip on the valve disc on the valve body will be reduced

Embodiment 1

[0026] For example figure 1 -example Figure 5 Shown:

[0027] The present invention provides a high sealing hydraulic valve, the structure of which comprises a rotating disc 1, a valve stem 2, a valve body 3, a mud discharge mechanism 4, and a communication port 5, the rotating disc 1 is welded to the valve stem 2, and the exhaust The mud mechanism 4 is embedded in the bottom position of the valve body 3 , the communication port 5 and the valve body 3 are an integral structure, and the valve stem 2 is screwed to the valve body 3 .

[0028] Wherein, the valve rod 2 includes a movable rod 21, a frame body 22, a sealing strip 23, a lifting block 24, a drain port 25, and a lower pressing block 26, and the movable rod 21 is threadedly connected with the frame body 22, and the sealing strip 23 The back side of the frame body 22 fits, the lifting block 24 is welded to the bottom position of the movable rod 21, the drain port 25 and the frame body 22 are an integrated structure, an...

Embodiment 2

[0034] For example Figure 6 -example Figure 8 Shown:

[0035] Wherein, the communication port 5 includes a bottom plate b1, a reset bar b2, a blocking block b3, and a sliding plate b4. The reset bar b2 is installed on the inner position of the bottom plate b1, and the blocking block b3 is embedded and connected with the sliding plate b4. The guide port b5 and the sliding plate b4 are integrally structured, the bottom of the bottom plate b1 is porous, and can discharge the sediment and water introduced into the bottom plate b1 together. There are five blocking blocks b3, which are evenly distributed The sliding plate b4 is fan-shaped, and can be inserted into the hole at the bottom of the bottom plate b1 when the sliding plate b4 slides down along the bottom plate b1 under the pressure of a large amount of water flow, so as to prevent the water flow from passing through the bottom of the bottom plate b1 when the mechanism is transporting the water flow outflow from the hole...

Abstract

The invention discloses a high-sealing-performance hydraulic valve. The high-sealing-performance hydraulic valve structurally comprises a rotary disc, a valve rod, a valve body, a mud discharge mechanism and a communicating opening. The rotary disc and the valve rod are welded, the mud discharge mechanism is embedded into the bottom position of the valve body, the communicating opening and the valve body are of an integrated structure, the valve rod and the valve body are in threaded connection, when water currents in the valve body need to be cut off, a movable rod rotates to descend, a waterguide opening in a lifting block can scrape away silt attached to the surface of a frame body, the phenomenon that a sealing strip on the frame body is abraded is effectively avoided, when the framebody cuts off water current transportation on the two sides in the valve body, a guide opening in the mud discharge mechanism is not extruded by a large quantity of water currents, thus, a reset stripcan push the guide opening to be slidingly reset upwards along a bottom plate, thus, the water and the silt are discharged together through holes in the bottom of the bottom plate, and the situationthat the silt scraped off by the lifting block stays at the bottom of the lifting block is avoided.

Description

technical field [0001] The invention relates to the field of hydraulic valves, in particular to a high-tightness hydraulic valve. Background technique [0002] The hydraulic globe valve is a forced sealing valve, which is mainly lowered by turning the valve stem, so that the sealing ring on the valve disc can cut off the material transported on both sides of the valve body. It is widely used in water source transportation and gas transportation and other industries. Based on the above Description The inventors found that an existing high-tightness hydraulic valve mainly has the following deficiencies, for example: [0003] Since the sediment at the bottom of the reservoir after the heavy rain is easy to float upwards, the pipeline for transporting the water source of the reservoir is easy to enter the sediment, so that the sediment will pass through the inner wall of the connecting port of the valve body. If the valve is closed at this time, the sealing strip on the valve di...
