In order to solve the technical problem, the utility model provides a gas valve device convenient to dismantle, include control flap and connect in the mounting flange of valve both sides, its characterized in that: mounting flange is equipped with a plurality of mounting holes along self circumferencial direction spaced apart, can dismantle between two mounting flanges and be connected with the action bars, and the external diameter of action bars sets up the internal diameter for the mounting hole less than or equal to, the length of action bars sets up the interval for being greater than two mounting flanges, the action bars is including locating the bracing piece between two mounting flanges and seting up the internal thread at bracing piece length both ends, still the cover is equipped with two and internal thread assorted nut on the action bars, and the external diameter of nut sets up the internal diameter for being greater than the mounting hole.
The technical effects are as follows: when the control valve is disassembled and replaced, the valve plate can not be completely closed to cause the valve plate to be clamped between the two mounting flanges and can not be taken down, at the moment, the operating rod is inserted into one of the mounting flanges through the mounting hole, one end of the operating rod is positioned between the two mounting flanges, then the two nuts are respectively sleeved at the end part and are rotated to the supporting rod, the end part is then penetrated through the other mounting flange, the operating rod is simultaneously penetrated and arranged on the two mounting flanges, at the moment, the two nuts are also positioned between the two mounting flanges, the two nuts are respectively rotated to be abutted against the mounting flanges at the corresponding sides and are continuously rotated, and due to the threaded connection between the threads and the internal threads, the rotation of the nuts can generate driving force to the mounting flanges, so that the two mounting flanges are separated from the control valve, and the control valve can be conveniently disassembled by an operator, on the one hand, the safety is improved, and on the other hand, the maintenance efficiency of the equipment is also improved.
The utility model discloses the technical scheme who further injects is:
further, the outer diameter of the operating rod is set to be equal to the inner diameter of the mounting hole.
The internal thread is symmetrically arranged along the length direction of the supporting rod.
The gas valve device convenient to disassemble is characterized in that the mounting holes are arranged at equal intervals along the circumferential direction of the mounting flange.
The gas valve device convenient to disassemble is characterized in that the nut is a hexagon nut.
The utility model has the advantages that:
(1) in the utility model, the outer diameter of the operating rod is arranged, so that the operating rod is more tightly connected with the mounting flange, and when an operator operates the nut, the operating rod is not easy to shake, so that the nut can directly and effectively provide driving force for the mounting flange, and the convenience and the stability of the use of the whole operating rod are improved;
(2) in the utility model, the internal thread is symmetrically arranged, so that the whole structure of the whole operating rod is more reasonable, the use is more convenient, the mounting holes are arranged, the structure of the whole mounting flange is higher, the operating rod is more convenient to connect between two mounting flanges, the nut is more convenient to rotate by an operator, and the control valve is more convenient to disassemble by the operator;
(3) the utility model discloses in, the shape setting of nut for when operating personnel rotated the nut, operating personnel's hand was easily carried out the application of force to the screw thread more, thereby has strengthened the convenience of nut rotation operation greatly, also labour saving and time saving more.
Drawings
Fig. 1 is a schematic view showing an overall structure of a gas valve assembly which is easily disassembled.
Wherein: 1. a control valve; 2. installing a flange; 21. mounting holes; 3. an operating lever; 31. a support bar; 32. an internal thread; 4. and a nut.
Detailed Description
The gas valve device convenient to dismantle that this embodiment provided, the structure is shown in fig. 1, control valve 1 and connect in the mounting flange 2 of valve both sides, and mounting flange 2 is equipped with a plurality of mounting holes 21 along self circumferencial direction interval, and mounting hole 21 is along the equidistant interval setting of mounting flange 2's circumferencial direction.
Can dismantle between two mounting flanges 2 and be connected with action bars 3, and the external diameter of action bars 3 sets up the internal diameter that equals mounting hole 21, the length of action bars 3 sets up the interval that is greater than two mounting flanges 2, action bars 3 is including locating bracing piece 31 between two mounting flanges 2 and seting up the internal thread 32 at bracing piece 31 length both ends, internal thread 32 sets up along the length direction symmetry of bracing piece 31, still the cover is equipped with two and internal thread 32 assorted nut 4 on the action bars 3, and the external diameter of nut 4 sets up the internal diameter that is greater than mounting hole 21, nut 4 sets up to hexagon nut.
When the control valve 1 is disassembled and replaced, the valve plate can not be completely closed to cause the valve plate to be clamped between the two mounting flanges 2 and can not be taken down, at the moment, the operating rod 3 is inserted into one of the mounting flanges 2 through the mounting hole 21, one end of the operating rod 3 is positioned between the two mounting flanges 2, then the two nuts 4 are respectively sleeved at the end part and are rotated to the supporting rod 31, the end part passes through the other mounting flange 2, the operating rod 3 simultaneously penetrates through the two mounting flanges 2, at the moment, the two nuts 4 are also positioned between the two mounting flanges 2, the two nuts 4 are respectively rotated to be abutted against the mounting flanges 2 at the corresponding sides and are continuously rotated, and due to the threaded connection between the threads and the internal threads 32, the rotation of the nuts 4 can generate driving force on the mounting flanges 2, so that the two mounting flanges 2 are separated from the control valve 1, the control valve 1 is convenient to detach by operators, so that the safety is improved on one hand, and the maintenance efficiency of the equipment is also improved on the other hand.
