Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a rising stem soft-sealed copper core gate valve. Background Art

[0002] Rising stem soft-sealed gate valve is an industrial valve. The opening and closing part of the soft-sealed gate valve is the gate. The movement direction of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The valve stem of the rising stem soft-sealed copper core gate valve can clearly show the opening and closing of the valve.

[0003] However, it still has the following disadvantages in actual use:

[0004] When the existing rising-stem soft-sealed copper core gate valve is in use, the valve stem is moved up and down by turning the handle. However, due to the large diameter of the handle, it is necessary to use both hands to turn it, which reduces the efficiency of the handle. At the same time, since the valve stem moves vertically up and down, it is easy for the staff to touch it when it moves to the upper part, causing harm to the staff, thereby reducing the safety of the device. Utility Model Content

[0005] The utility model aims to provide a rising stem soft-sealed copper core gate valve to solve the problem raised in the above-mentioned background technology that, when the existing rising stem soft-sealed copper core gate valve is in use, the valve stem is moved up and down by rotating the handle, and the handle has a large diameter when in use, so it is necessary to use both hands to rotate it, which reduces the efficiency of the handle. At the same time, since the valve stem moves vertically up and down, it is easy to be touched by the staff when the valve stem moves upward, causing harm to the staff, thereby reducing the safety of the device.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model is a rising stem soft-sealed copper core gate valve, comprising:

[0008] A valve body, the valve body comprising a valve body, a valve cover, a handle and a valve stem;

[0009] A supporting component, the supporting component comprising a supporting frame and a supporting plate;

[0010] A driving component, the driving component comprising a gear ring, a gear, a mounting frame, a handle, a rotating shaft and a threaded tube;

[0011] The valve cover is fixedly installed on the top end of the valve body, the support frames are symmetrically fixedly connected to the two sides of the valve cover, the support frames are all L-shaped, the bottom surface of the support plate is fixedly connected to the top surface of the support frame, the handle is arranged above the support plate, the threaded tube is fixedly connected to the inside of the handle, and the valve stem is threadedly connected to the inside of the threaded tube, and enters the inside of the valve body by passing through the inside of the support plate and the valve cover, the mounting frame is fixedly installed on the top surface of the support plate, the mounting frame is U-shaped, the gear is arranged between the mounting frame and the support plate, the rotating shaft is fixedly connected to the inside of the gear, and the upper and lower ends are respectively rotatably connected to the side walls of the mounting frame and the support plate, the handle is rotatably connected to the top surface of the mounting frame, and is fixedly connected to the top of the rotating shaft by passing through the inside of the mounting frame, the gear ring is fixedly sleeved and installed on the outer side wall of the handle, and the gear ring is meshed with the gear.

[0012] Furthermore, the support component also includes a placement rack;

[0013] The placement rack is respectively fixedly connected to the front and rear side walls and the left side wall of the support plate. The placement rack is L-shaped, and the top of the placement rack is fixedly connected. The centerline axis of the valve stem and the axis of the placement rack are on the same axis.

[0014] Furthermore, the bottom of the threaded tube passes through the interior of the support plate and is rotatably connected to the interior of the support plate, and the bottom of the threaded tube is rotatably connected to the top surface of the valve cover.

[0015] Furthermore, the bottom surfaces of the handle, the gear ring and the gear do not contact the top surface of the support plate.

[0016] Furthermore, the diameter of the gear is smaller than the diameter of the gear ring.

[0017] Furthermore, the top surfaces of the placement racks are all rounded.

[0018] Compared with the prior art, the advantages of the present invention are:

[0019] The utility model can conveniently rotate the gear by turning the handle when the rising-stem soft-sealed copper-core gate valve is in use, thereby causing the gear to drive the gear ring to rotate, and the gear ring can drive the handle to rotate as a whole, thereby conveniently causing the valve stem to move up and down, and when the valve stem moves upward, the top end of the valve stem can be shielded by the placement rack to prevent the staff from colliding with the valve stem.

[0020] Based on the above beneficial effects, the handle can be easily rotated by setting the gears and gear rings. Since the diameter of the gears is small, the rotation range of the handle is small, which can effectively reduce the labor intensity of the staff. At the same time, the placement rack can be used to block the valve stem to simply protect the staff and prevent the staff from colliding with the valve stem. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] By turning the handle 34, the gear 32 can be easily rotated, so that the handle 13 can be rotated, and the internal threaded tube 36 and the valve stem 14 can cooperate to make the valve stem 14 move up and down conveniently;

[0038] Working principle: When using the valve body, when it is necessary to open the interior of the valve body 11, turn the handle 34 to rotate the gear 32, so that the gear ring 31 can easily drive the handle 13 to rotate, and the valve stem 14 can move upward to open the interior of the valve body 11. When closing, turn the handle 34 in the opposite direction to move the valve stem 14 downward, so that the interior of the valve body 11 can be easily closed.

[0039] See also Figure 1-3 As shown, this embodiment is based on the above embodiment 1, and the supporting component further includes a placement rack 23;

[0040] The placement rack 23 is respectively fixedly connected to the front and rear side walls and the left side wall of the support plate 22.

[0046] The diameter of the gear 32 is smaller than the diameter of the gear ring 31;

[0047] The small diameter of the gear 32 can reduce the rotation distance and reduce the labor intensity of the staff;

[0048] The top surfaces of the placement racks 23 are all rounded;

[0049] The top surface of the placement rack 23 is rounded, which can enhance the protection of the valve body to the staff;

[0050] Working principle: When the valve stem 14 moves upward, the top of the valve stem 14 hits the side wall of the placement rack 24, which can prevent the staff from colliding with the valve stem 11 and avoid accidental injury to the staff. At the same time, the staff can judge the switch of the valve body 11 according to the leakage of the valve stem 14.
