DETAILED DESCRIPTION

[0016] The embodiments of the utility model will be described in detail below, the examples of the embodiments are shown in the drawings, the embodiments described below are exemplary and are intended to explain the utility model, and cannot be understood as the limitation of the utility model.

[0017] Please refer to Figure 1 And Figure 2 Among them Figure 1 It is the structure schematic view of the umbrella gear double-seal gapless valve of the utility model, Figure 2 It is the partial structure schematic view of the umbrella gear double-seal gapless valve of the utility model.

[0018] The utility model provides a kind of bevel gear double-sealing gapless valve, including valve body 101, bidirectional valve seat 102, connecting piece 103, bevel gear device 104, force assembly, connecting rod 105 and shutter 106, the bidirectional valve seat 102 is installed in the two sides of the valve body 101, the connecting piece 103 is fixedly connected with the upper end of the valve body 101, the bevel gear device 104 is arranged on the connecting piece 103, and the connecting rod 105 is connected with the device of bevel gear, the other end of the connecting rod 105 is fixedly connected with the shutter 106, the shutter 106 is placed in the bidirectional valve seat 102, the force assembly is used to drive the bevel gear device 104, rectangular sealing ring 116 is also provided on the valve body 101;

[0019] The lower end of the shutter 106 is wedge-shaped.

[0020] For this specific embodiment, in specific use, the shutter 106 is opened and closed by the force assembly driving the bevel gear to move the connecting rod 105. Due to the high transmission efficiency of the bevel gear device 104, the shutter 106 can be frequently opened and closed. When the shutter 106 is opened, the medium flows into the pipeline through the valve body 101. The valve body 101 with the bidirectional valve seat 102 installed will not overflow the medium to the outside. When the shutter 106 is closed, the bidirectional valve seat 102 prevents the medium from overflowing to the inside. The shutter 106 blocks the medium from flowing in at the outlet end of the valve body 101. When the bidirectional valve seat 102 wears out, it can be replaced directly without replacing the entire valve, which is more cost-effective and easier to maintain. This way solves the technical problem of the existing technology, which requires frequent opening and closing of the valve in some situations, and the existing valve has low transmission efficiency when opening and closing, making it inconvenient to open and close frequently.

[0021] The lower end of the shutter 106 is wedge-shaped, which seals the bidirectional valve seat 102 without damaging it. When the shutter 106 is closed, it presses the bidirectional valve seat 102 to widen the sealing line and increase the seal. The wedge-shaped shutter 106 can cut slag during opening and closing, increasing the sealing performance.

[0022] The force assembly includes a block 107, a bracket 108, and a grip rod 109. The block 107 is connected to the bevel gear device 104. The bracket 108 is arranged between the block 107 and the grip rod 109.

[0023] For this specific embodiment, the block 107 is driven to rotate by holding the holding rod 109 and rotating the bracket 108 through the holding rod 109, and the block 107 drives the connecting rod 105 to move through the bevel gear device 104 to realize the opening and closing of the gate plate 106.

[0024] Secondly, the bevel gear double-seal gapless valve further comprises a packing 110 and a gland 111, and the packing 110 is pressed on the rectangular sealing ring 116 through the gland 111.

[0025] For this specific embodiment, the packing 110 is pressed on the rectangular sealing ring 116 through the gland 111 to improve the sealing effect.

[0026] Meanwhile, the bevel gear double-seal gapless valve further comprises a slag discharge device 112, and the slag discharge device 112 is welded with the lower end of the valve body 101.

[0027] For this specific embodiment, the slag discharge device 112 is used to discharge the waste slag cut by the gate plate 106.

[0028] In addition, the bidirectional valve seat 102 comprises a framework 113 and a rubber lining 114, the framework 113 is connected with the valve body 101, the framework 113 has a groove 115, and the rubber lining 114 is arranged in the groove 115.

[0029] The holding rod 109 has a circular arc surface,

[0030] For this specific embodiment, the rubber lining 114 is made of natural rubber, and the circular arc surface can comfortably hold the holding rod 109.

[0031] When the bevel gear double-seal gapless valve is used, the connecting rod 105 is driven to move through the force applying assembly to realize the opening and closing of the gate plate 106, and the gate plate 106 can be frequently opened and closed due to the high transmission efficiency of the bevel gear device 104. When the gate plate 106 is opened, the medium flows into the pipeline through the valve body 101, and the medium cannot overflow to the outside of the valve body 101 which is installed with the bidirectional valve seat 102. When the gate plate 106 is closed, the bidirectional valve seat 102 prevents the medium from overflowing to the inside, and the gate plate 106 prevents the medium from flowing into the outlet end of the valve body 101. When the bidirectional valve seat 102 is worn, the bidirectional valve seat 102 can be directly replaced, and the whole valve does not need to be replaced, which is lower in use cost and convenient to maintain. In this way, the technical problem that the existing valve has low transmission efficiency when being opened and closed and is inconvenient to frequently open and close in some occasions is solved.

[0032] The utility model discloses beneficial effect is:

[0033] 1, the bevel gear double seal gapless valve is wear -resisting, and the anti -erosion, prevents the leakage, and product sealing performance is durable good, and the bidirectional valve seat 102 can replace, and equipment maintenance is convenient, improves the service life of the bevel gear double seal gapless valve.

[0034] 2, the bevel gear double seal gapless valve adopts the special said residue discharging device 112, can discharge the residue liquid of the valve body 101, promotes the use efficiency of the gate 106, reduces the wear of the valve body 101, and the service life is long. Can be used in the occasion such as the slurry of fine particle material conveying pipeline of mine, metallurgy, power plant, coal, chemical industry and so on in the public diameter is 1200mm below.

[0035] 3, the bidirectional valve seat 102 built-in special reinforcing framework 113, can greatly increase the valve seat 102 strength, also can make equipment stable operation under harsh conditions.

[0036] 4, the valve body 101 upper end with the rectangular sealing ring 116 in the cavity has sealing groove, and the gate forms upper sealing with the rectangular sealing ring 116 in the switching process, so that medium does not leak upwards

[0037] 5, the valve body 101 upper end is equipped with the packing box inside packing 110 and is compressed with the gland 111, enhances the sealing property while making it with the rectangular sealing ring 116, the valve body 101, the gate 106 form integral sealing effect.

[0038] 6, the bevel gear device 104 makes the bevel gear double seal gapless valve operation more portable and efficient, and because of the characteristics of bevel gear, the bevel gear double seal gapless valve can be frequently switched when operating.

[0039] The above disclosed is only a preferred embodiment of the utility model, of course can not with this to limit the right range of the utility model, and the person skilled in the art can understand that the whole or part of the process of the above embodiment is realized, and the equivalent change made by the utility model right claim still belongs to the range covered by the utility model.
