Description

Technical Field

[0001] The utility model relates to the technical field of bellows gate valves, in particular to a double-sealed bellows gate valve with high stability. Background Art

[0002] The double-sealed bellows gate valve is a special valve. It combines the working principle of the gate valve on the basis of the bellows and has a double-layer sealing design. The bellows is a pipe composed of a series of corrugated structures, with good elasticity and pressure-bearing capacity. The bellows can control the on-off of the fluid by changing the shape and position of the corrugations, realizing the opening and closing control of the valve. It has a simpler structure than traditional valves, is flexible in operation, and has good sealing performance.

[0003] During the use of the existing bellows gate valves on the market, it is impossible to ensure the connection stability of the overall device while also ensuring its stable sealing state during operation; for this reason, a double-sealed bellows gate valve with high stability is proposed. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the defects existing in the prior art, and to propose a double-sealed bellows gate valve with high stability.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A double-sealed bellows gate valve with high stability, including a valve body and an adjustment unit. The adjustment unit is installed on the upper end face of the valve body. The adjustment unit includes an elastic mechanism and an adjustment unit arranged on the upper end face of the elastic mechanism. A blocking mechanism is vertically inserted through the inner cavities of the elastic mechanism and the adjustment unit.

[0007] Preferably, the elastic mechanism includes a bottom column and an elastic member installed on the upper end face of the bottom column. A pressing disc is arranged at the top of the elastic member, and elastic pieces are annularly arranged on the outer ring of the pressing disc.

[0008] The bottom column and the pressing disc are elastically connected through the elastic member. Since the bottom end face of the elastic piece is connected to the outer end wall of the valve body, the elastic piece will protrude outwards while the pressing disc is pressed downwards. The protruding elastic piece can protect the overall adjustment unit from the side.

[0009] Preferably, the adjustment unit includes a support vertical rod and an installation fan blade installed at the top position of the support vertical rod. Multiple groups of the installation fan blades are connected in series through connecting pieces. A connecting cross bar is horizontally arranged on the inner end wall of the installation fan blade. The other ends of multiple groups of the connecting cross bars are connected to a combined ring piece, and multiple groups of the combined ring pieces are spliced together.

[0010] The staff can squeeze and install the fan blades from the outside to the inside, causing multiple groups of installation fan blades to turn inward. At this time, the distance between the installation fan blades and the connection pieces is reduced, and a morphological change occurs, prompting the simultaneous change of the shapes of other components such as the connecting crossbar and the combined ring. Under the morphological change of the installation fan blades, the shapes of the connecting crossbar and the combined ring change simultaneously. The connecting crossbar and the combined ring tilt downward, and the vertical cylinder is pressed downward under the driving of the downward pressing force of the combined ring, causing the entire blocking mechanism to be pressed by the vertical cylinder, thereby improving the connection stability between the adjusting unit and the blocking mechanism to ensure that the double-sealed bellows gate valve can maintain a stable sealing state during operation.

[0011] Preferably, the blocking mechanism includes a chassis and a blocking ball installed on the upper end surface of the chassis. A wrapping member is connected above the blocking ball, and a bearing plate is provided at the top of the wrapping member. A vertical cylinder is vertically arranged directly above the bearing plate.

[0012] The provided vertical cylinder can exert a downward impact force on the bearing plate. Under the downward impact state, the bearing plate and the wrapping member press downward on the upper end surface of the blocking ball, enabling the wrapping member to wrap around the outer surface of the blocking ball as a path. The outer end wall of the wrapping member in the wrapped state fits against the inner cavity wall of the valve body, thereby ensuring that the double-sealed bellows gate valve can maintain a stable sealing state during operation.

[0013] Preferably, the vertical cylinder is vertically inserted from bottom to top into the inner cavity of the annular member formed between multiple groups of combined rings.

[0014] Preferably, the chassis, the blocking ball, and the wrapping member vertically extend downward into the inner cavity of the valve body.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] 1. The bottom column and the pressing plate are elastically connected through an elastic member. Since the bottom end surface of the elastic sheet is connected to the outer end wall of the valve body, the elastic sheet will protrude outward while the pressing plate is pressed downward. The protruding elastic sheet can protect the entire adjusting unit on the side.

[0017] 2. The staff can squeeze and install the fan blades from the outside to the inside, causing multiple groups of installation fan blades to turn inward. At this time, the distance between the installation fan blades and the connection pieces is reduced, and a morphological change occurs, prompting the simultaneous change of the shapes of other components such as the connecting crossbar and the combined ring. Under the morphological change of the installation fan blades, the shapes of the connecting crossbar and the combined ring change simultaneously. The connecting crossbar and the combined ring tilt downward, and the vertical cylinder is pressed downward under the driving of the downward pressing force of the combined ring, causing the entire blocking mechanism to be pressed by the vertical cylinder, thereby improving the connection stability between the adjusting unit and the blocking mechanism to ensure that the double-sealed bellows gate valve can maintain a stable sealing state during operation.

[0018] 3. The vertically arranged cylinder can apply a downward pressing impact force to the bearing plate. When the bearing plate is in the downward pressing impact state, the bearing plate and the package press down the upper end surface of the blocking ball, enabling the package to wrap around the outer surface of the blocking ball as a path. The outer end wall of the package in the wrapped state fits against the inner cavity wall of the valve body, thereby ensuring that the double-sealed bellows gate valve can maintain a stable sealing state during operation.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0025] Refer to Figures 1 - 4 , a highly stable double-sealed bellows gate valve, including a valve body 1 and an adjustment unit 2. The adjustment unit 2 is installed on the upper end surface of the valve body 1. The adjustment unit 2 includes an elastic mechanism 21 and an adjustment unit 22 arranged on the upper end surface of the elastic mechanism 21. A blocking mechanism 23 is vertically inserted through the inner cavities of the elastic mechanism 21 and the adjustment unit 22.

[0026] The elastic mechanism 21 includes a bottom column 211 and an elastic member 212 installed on the upper end surface of the bottom column 211. A downward pressing plate 213 is arranged at the top of the elastic member 212, and elastic sheets 214 are annularly arranged around the outer circle of the downward pressing plate 213.

[0027] The provided bottom column 211 and the lower pressing plate 213 are elastically connected through an elastic member 212. Since the bottom end surface of the elastic piece 214 is connected to the outer end wall of the valve body 1, when the lower pressing plate 213 is pressed downward, the elastic piece 214 will protrude outward. The protruding elastic piece 214 can protect the adjustment unit 2 as a whole on the side.

[0028] The adjusting unit 22 includes a supporting vertical rod 221 and mounting fan blades 222 installed at the top of the supporting vertical rod 221. Multiple groups of mounting fan blades 222 are connected in series through connecting pieces 223. The inner end walls of the mounting fan blades 222 are horizontally provided with connecting cross rods 224. The other ends of multiple groups of connecting cross rods 224 are connected to a combined ring piece 225, and multiple groups of combined ring pieces 225 are spliced together.

[0029] The staff can squeeze the mounting fan blades 222 from the outside to the inside, causing multiple groups of mounting fan blades 222 to turn inward. At this time, the distance between the mounting fan blades 222 and the connecting pieces 223 is reduced, and a morphological change occurs, prompting the morphological changes of other components such as the connecting cross rods 224 and the combined ring pieces 225 at the same time. Under the morphological change of the mounting fan blades 222, the morphological changes of the connecting cross rods 224 and the combined ring pieces 225 occur simultaneously. The connecting cross rods 224 and the combined ring pieces 225 tilt downward, and the vertical cylinder 235 is pressed downward under the driving force of the downward pressing force of the combined ring piece 225, causing the blocking mechanism 23 as a whole to be pressed by the vertical cylinder 235, thereby improving the connection stability between the adjusting unit 22 and the blocking mechanism 23 to ensure that the double-sealed bellows gate valve can maintain a stable sealing state during operation.

[0030] The blocking mechanism 23 includes a chassis 231 and a blocking ball 232 installed on the upper end surface of the chassis 231. A wrapping member 233 is connected above the blocking ball 232. A bearing plate 234 is provided at the top of the wrapping member 233, and a vertical cylinder 235 is vertically arranged above the bearing plate 234.

[0031] The provided vertical cylinder 235 can exert a downward pressing impact force on the bearing plate 234. Under the downward pressing impact state, the bearing plate 234 and the wrapping member 233 press the upper end surface of the blocking ball 232 downward, enabling the wrapping member 233 to wrap around the outer surface of the blocking ball 232 as a path. The outer end wall of the wrapping member 233 in the wrapped state fits against the inner cavity wall of the valve body 1, thereby ensuring that the double-sealed bellows gate valve can maintain a stable sealing state during operation. The vertical cylinder 235 is vertically inserted from bottom to top into the inner cavity of the annular member formed between multiple groups of combined ring pieces 225, and the chassis 231, the blocking ball 232, and the wrapping member 233 vertically extend downward into the inner cavity of the valve body 1.

[0032] In summary: A double-sealed bellows gate valve with high stability includes a valve body 1 and an adjustment unit 2. The adjustment unit 2 is installed on the upper end surface of the valve body 1. The adjustment unit 2 includes an elastic mechanism 21 and an adjustment unit 22 arranged on the upper end surface of the elastic mechanism 21. A blocking mechanism 23 is vertically inserted through the inner cavities of the elastic mechanism 21 and the adjustment unit 22;

[0033] The bottom column 211 and the lower pressing plate 213 are elastically connected through an elastic member 212. Since the bottom end surface of the elastic piece 214 is connected to the outer end wall of the valve body 1, when the lower pressing plate 213 is pressed downward, the elastic piece 214 will protrude outward. The protruding elastic piece 214 can protect the entire adjustment unit 2 from the side.

[0034] The staff can squeeze the installation fan blades 222 from the outside to the inside, causing multiple groups of installation fan blades 222 to turn inward. At this time, the distance between the installation fan blades 222 and the connecting piece 223 is reduced, and a morphological change occurs, prompting the morphological changes of other components such as (224) and (225) at the same time. Under the morphological change of the installation fan blades 222, the connecting cross bar 224 and the combined ring piece 225 change their shapes simultaneously. The connecting cross bar 224 and the combined ring piece 225 tilt downward, and the vertical cylinder 235 is pressed downward under the driving force of the downward pressing force of the combined ring piece 225, causing the entire blocking mechanism 23 to be pressed by the vertical cylinder 235, thereby improving the connection stability between the adjustment unit 22 and the blocking mechanism 23 to ensure that the double-sealed bellows gate valve can maintain a stable sealing state during operation.

[0035] The provided vertical cylinder 235 can exert a downward pressing impact force on the bearing plate 234. Under the downward impact state, the bearing plate 234 and the wrapping member 233 press the upper end surface of the blocking ball 232 downward, enabling the wrapping member 233 to wrap around the outer surface of the blocking ball 232 as a path. The outer end wall of the wrapping member 233 in the wrapped state fits against the inner cavity wall of the valve body 1, thereby ensuring that the double-sealed bellows gate valve can maintain a stable sealing state during operation.

Any other changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be equivalent replacement methods and are all included in the protection scope of the present utility model.
