Description

Valve with internal pre-tightening function

Technical Field

The invention relates to the technical field of valves, in particular to an internal pre-tightening valve.

Background

The valve is a device that can control the flow rate of a medium (liquid, gas, or powder) in a pipe or a device by flowing or stopping the medium. The valve is a control component in the pipeline fluid conveying system, is used for changing the section of a passage and the flowing direction of a medium, and has the functions of diversion, cut-off, adjustment, throttling, check, diversion or overflow pressure relief and the like. The valve is widely applied to various industries of industrial production and life and is an indispensable device for domestic water pipelines and industrial fluid pipelines.

When the valve cuts off water flow, a split structure is adopted between the valve clack and parts around the valve clack, gaps are easy to appear around the valve clack, sealing is not tight, and water flow leaks out from the gaps. Particularly, when the impact force of water flow in the water inlet pipe is large, the upward extrusion force of the water flow on the valve clack is large, so that gaps are easy to appear around the valve clack to cause liquid leakage. The valve clack of the existing valve is only simply extruded between the water inlet pipe and the water outlet pipe, and the valve clack lacks necessary pre-tightening components and cannot apply pressing force to the valve clack, so that liquid leakage is easy to occur.

Therefore, there is a need to provide an internally preloaded valve that provides a preload that is good in sealing performance.

The upper side surfaces of the first partition block and the second partition block are inclined.

(2) The first screw rod is rotated as required, the extrusion degree of the first screw rod to the first sealing frame is adjusted, and when the downward extrusion acting force of the first screw rod to the first sealing frame is larger, the first sealing frame can be tightly attached to the upper side of the first separation block, so that the sealing performance is improved. When the water flow upwards impacts the valve clack, the valve clack upwards pushes the sealing plate, the sealing strip and the first sealing frame, the first sealing frame transmits the received extrusion force to the third spring, the third spring deforms to relieve the extrusion force, the buffer protection effect is achieved, and meanwhile the bearing capacity of the first sealing frame is improved.

The sealing plate can upwards extrude the second spring after receiving the extrusion force, and the second spring upwards extrudes the regulating plate, and the regulating plate extrudes the first spring. The second spring and the first spring are extruded to generate deformation so as to relieve extrusion force generated by water flow impact action, and the buffer protection function is achieved. Meanwhile, the reverse acting force generated by the second spring and the first spring is finally transmitted to the valve clack and the sealing plate, so that stable and firm sealing of the valve clack and the sealing plate to the water passing gap between the first separation block and the second separation block is ensured, and the phenomenon that looseness occurs under water flow impact to cause water flow leakage is avoided.

When the adjusting plate rotates downwards for a larger length, the second spring generates larger deformation, and the corresponding extrusion pretightening force applied to the sealing plate is larger, so that the opposite pressure of the water flow can be borne is larger. The capacity of the sealing plate and the valve clack for bearing water flow is adjusted by adjusting the axial position of the adjusting plate.

The sealing plate 612 is circular, and the sealing plate 612 is screwed to the lower end of the operating rod 61. The first seal frame 69 is arc-shaped, and the first seal frame 69 is bolted to an edge of one side of the seal plate 612, the first seal frame 69 extending along the arc direction of the seal plate 612. The first seal frame 69 is provided with a first adjusting groove in a penetrating manner, and the longitudinal section of the first adjusting groove is trapezoidal. The first regulating groove extends along the circular arc direction of the first sealing frame 69. The lower side of the first sealing frame 69 is inclined.

Wherein the upper sides of the first and second dividing blocks 34 and 37 are inclined. In use, the lower side of the sealing plate 612 is pressed against the upper side of the second spacer 37, and the surfaces contacting each other are inclined planes, thereby achieving close contact and improving sealing performance.

The lower side of the first sealing frame 69 is extruded on the upper side of the first separation block 34, and the lower side of the first sealing frame 69 and the upper side of the first separation block 34 are inclined planes, so that tight contact is realized, and the sealing performance is improved. The first screw 68 is rotated as required, the extrusion degree of the first screw 68 to the first sealing frame 69 is adjusted, and when the downward extrusion acting force of the first screw 68 to the first sealing frame 69 is larger, the first sealing frame 69 can be tightly attached to the upper side of the first separation block 34, so that the sealing performance is improved.

The second spring 67 and the first spring 62 are pressed to deform so as to relieve the pressing force generated by the impact of water flow, and the buffer protection function is achieved. Meanwhile, the reverse acting force generated by the second spring 67 and the first spring 62 is finally transmitted to the valve clack 611 and the sealing plate 612, so that stable and firm sealing of the valve clack 611 and the sealing plate 612 to the water gap between the first separation block 34 and the second separation block 37 is ensured, and loosening under water flow impact is avoided, so that water flow leakage is avoided.

By rotating the regulating plate 65, the regulating plate 65 rotates along the axial direction of the operating rod 61 and presses the second spring 67 downward, the second spring 67 is pressed to deform and generate a corresponding acting force to the sealing plate 612, and extrusion pre-tightening of the sealing plate 612 is achieved. When the adjusting plate 65 rotates downward for a larger length, the second spring 67 deforms more, and accordingly the pressing pre-tightening force applied to the sealing plate 612 is larger, so that the opposite pressure of the water flow can be borne. The ability of the sealing plate 612 and the valve flap 611 to carry water flow is adjusted by adjusting the axial position of the adjustment plate 65.

The inclination direction of the rubber sheet 6127 coincides with the inclination direction of the side wall of the lower portion of the first plate body 6123.

When the sealing device is used, the first adjusting rod 6121 is rotated, the first adjusting rod 6121 pushes the extrusion block 6125 downwards, the extrusion block 6125 slides downwards and pushes the sliding block 6126, the sliding block 6126 pushes the rubber sheet 6127 relatively, and the rubber sheet 6127 is extruded downwards at the edge of the upper sides of the first separation block 34 and the second separation block 37, so that the sealing of a gap between the sealing plate 612 and the first separation block 34 and the second separation block 37 is realized, and water leakage is avoided. Finally, the first adjusting rod 6121 is screwed by the first screw tube 6122, so that the position of the first adjusting rod 6121 is fixed.

The length of rotation of the first regulating lever 6121 is adjusted according to the pressure of the water. When the length of the first adjusting lever 6121 rotating downward is large, the pressing force of the rubber sheet 6127 to the first and second dividing blocks 34 and 37 is large, and a large water pressure can be borne. In contrast, when the length of the rotation of the first regulating lever 6121 is small, a small water pressure can be received.

When water pressure acts on the lower side of the rubber sheet 6127, acting force is transmitted to the fifth spring 6124, the fifth spring 6124 is extruded to generate deformation, and reverse extrusion force is transmitted to the rubber sheet 6127, so that the stress balance of the rubber sheet 6127 is ensured, and stable sealing is realized.
