Description
Technical field
The utility model is related to acetylene gas production equipment field more particularly to a kind of acetylene generator calcium carbide charging valves.
Background technology
Acetylene generator is the key equipment of calcium carbide method acetylene production, is given by calcium carbide bucket, upper bucket, lower bucket, oscillation
The part such as glassware and generator forms.Twice charging wherein between calcium carbide bucket and upper bucket, upper bucket and lower bucket
Valve plays a crucial role.Since the process that calcium carbide enters generator needs frequently, discontinuously to operate, twice charging valve
It must open, close regularly.If poorly sealed when closing, a large amount of acetylene can be caused in calcium carbide charging and reaction process
Gas leaks, and acetylene is flammable explosive gas, is mixed with air and safety accident easily occurs.
Factor of the existing calcium carbide charging valve due to overturning structure, causes in calcium carbide dropping process to the seal head in valve body
It impacts uneven, so as to cause valve body partial wear, finally influences the sealing performance of entire valve body.
Utility model content
The problem of for shortcomings and deficiencies in the prior art, the utility model proposes a kind of chargings of acetylene generator calcium carbide
Valve is avoided due to, to the impact of seal head, reducing the abrasion of seal head in calcium carbide dropping process, improving the close of charging valve
Sealing property.
Technical solution adopted by the utility model to solve its technical problems is：
A kind of acetylene generator calcium carbide charging valve, including valve body, valve seat, seal head, pivoted arm, fixing axle, clump weight, fixed cunning
Wheel and cylinder, the valve body top are equipped with valve seat, the buffer board of interlaced arrangement are equipped in valve seat, and mouth is equipped with sealing under valve seat
Circle, the seal head coordinated with mouth under valve seat are fixed on by pivoted arm in fixing axle, and fixing axle is mounted on valve body, the pivoted arm other end
It is connected with drawstring, drawstring bypasses fixed pulley and cylinders, and fixed pulley is separately fixed at cylinder on valve interior wall, and clump weight is solid
It is scheduled on the one end of pivoted arm close to drawstring.
Further, rubber block is used at the top of the seal head.
Further, the sealing ring is equipped with one layer of chimb, is mounted under valve seat in the groove of mouth by chimb insertion.
Further, the side of the valve body sets Packed maintenance door.
Further, stiffener plate is equipped between the buffer board and valve seat.
Further, the valve base inner wall by being equipped with abrasive rubber layer on charge level and buffer stopper.
The utility model has the advantages that：Sealing ring is embedded in using chimb in the groove of valve seat, and dismounting is safeguarded
Convenient, sealing effect is good；Valve base inner wall is equipped with abrasive rubber layer by charge level and buffer stopper, avoids calcium carbide in valve seat
The direct impact of wall and buffer board improves its service life, and subsequently only needs to change abrasive rubber layer, for enterprise saved at
This；The convenient repair and maintenance to equipment of maintenance door is arranged in valve body.
Description of the drawings
Fig. 1 is the utility model overall structure diagram.
Specific implementation mode
Specific embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings.
As shown in the figure：A kind of acetylene generator calcium carbide charging valve, including valve body 1, valve seat 2, seal head 3, pivoted arm 4, fixation
Axis 5, clump weight 6, fixed pulley 7 and cylinder 8,1 top of the valve body are equipped with valve seat 2, the buffer board of interlaced arrangement are equipped in valve seat 2
12,2 times mouths of valve seat are equipped with sealing ring 11, are fixed in fixing axle 5 by pivoted arm 4 with the seal head 3 of 2 times mouths of valve seat cooperation,
Fixing axle 5 is mounted on valve body 1, and 4 other end of pivoted arm is connected with drawstring, and drawstring is connected around fixed pulley 7 with cylinder 8, fixed pulley 7
It is separately fixed on 1 inner wall of valve body with cylinder 8, clump weight 6 is fixed on pivoted arm 4 close to one end of drawstring.
3 top of the seal head uses rubber block 21.
The sealing ring 11 is equipped with one layer of chimb, by chimb insertion in the groove of 2 times mouths of valve seat.
The side of the valve body 1 sets Packed maintenance door 31.
Stiffener plate 41 is equipped between the buffer board 12 and valve seat 2.
2 inner wall of the valve seat is equipped with abrasive rubber layer 42 by charge level and buffer stopper 12.
Specifically, when charging valve is closed, cylinder 8 is in stretching state, passes through the drawstring pine of fixed pulley 7
It relaxes, clump weight 6 pulls down pivoted arm 4 by gravity so that seal head 3 rises, closely sealed with 2 times mouths of valve seat.
When needing that calcium carbide is allowed to enter next equipment by charging valve, cylinder 8 contracts to recycling, and drawstring is driven to draw pivoted arm 4
It rises, so that seal head 3 is detached with valve seat 2, valve body 1 is in the open state.
When valve body 1 is closed, the calcium carbide of top falls, and the buffer board 12 that can pass through on valve seat 2 buffers, so as to avoid right
The partial wear directly caused by impact of seal head 3, reduces the influence to the sealing performance of charging valve, improves the safety of equipment
Performance.
Basic principles, main features, and advantages of the present invention has been shown and described above.This reality
It is not restricted to the described embodiments with novel, the above embodiments and description only describe the originals of the utility model
Reason, the utility model also has various changes and improvements on the premise of not departing from the spirit and scope of the utility model, these changes
Change and improve and both falls in claimed the scope of the utility model.The utility model requires protection scope is by appended right
Claim and its equivalent define.
