AI Technical Summary
The existing exhaust gas incinerator valves have severe wear and tear due to frequent opening and closing of the moving shaft and the guide mechanism due to severe opening and closing of the valves at high temperatures, which increases maintenance and maintenance costs.
The guide wheel is used to change the sliding friction between the moving shaft and the guide mechanism to rolling friction. The three guide wheels are evenly arranged in the circumferential direction to ensure that the moving shaft can only move axially, reduce wear and improve stability.
It effectively reduces wear of the moving shaft, improves the smoothness of the valve plate opening and closing and sealing performance, and reduces the maintenance and maintenance costs of the equipment.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of incinerators, in particular to a control valve for a waste gas incinerator. Background Art
[0002] In recent years, with the improvement of national ecological and environmental protection requirements, the application of various waste gas incinerator treatment equipment has become increasingly modernized. Since most waste gas treatment equipment needs to heat the waste gas to a high temperature for combustion, the valves of the incinerator usually use cylinders to connect the motion shaft for remote push-pull opening and closing control. However, due to the frequent opening and closing of the valve, the motion shaft constantly rubs against the guide mechanism at high temperature, resulting in severe wear and tear, requiring frequent maintenance. Utility Model Content
[0003] In view of this, the purpose of the utility model is to provide a waste gas incinerator control valve to address the deficiencies of the prior art, which converts the sliding friction between the moving shaft and the guide mechanism into rolling friction, reduces wear, and greatly reduces the maintenance and servicing costs of the equipment.
[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0005] A waste gas incinerator control valve comprises an incinerator, a cylinder, a moving shaft, a valve plate and a first guide mechanism. An opening is provided on the incinerator, a bracket is provided in front of the opening, the cylinder is provided on the bracket, the front end of the cylinder push rod is connected to the moving shaft and can drive it to move forward and backward, the valve plate is provided on the moving shaft, the valve plate is against the opening, the forward and backward movement of the moving shaft can make the valve plate contact or separate from the opening, the incinerator is provided with a first guide mechanism, the first guide mechanism comprises a base and three guide wheels provided on the base along a circumferential direction, the base is fixedly provided on the incinerator, the moving shaft passes through the centers of the three guide wheels and is rollingly connected with the three guide wheels.
[0006] Furthermore, the base is fixedly arranged at the center of the opening of the incinerator.
[0007] Furthermore, a second guide mechanism is provided on the bracket, and the motion axis passes through the second guide mechanism and the first guide mechanism in sequence.
[0008] Furthermore, the three guide wheels are evenly arranged along the circumferential direction.
[0009] The beneficial effects of the utility model are:
[0010] The utility model adopts three guide wheels to wrap the moving shaft from three angles, so that the moving shaft can only move axially, and the sliding friction between the moving shaft and the guide mechanism is changed into rolling friction, which reduces wear, makes the moving shaft move more smoothly, and makes the opening and closing of the valve plate smoother.

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0016] Reference Figure 1-Figure 3 The utility model provides a waste gas incinerator control valve, including an incinerator 1, a cylinder 2, a motion shaft 3, a valve plate 4 and a first guide mechanism 5. An opening 101 is provided on the incinerator 1, a bracket 6 is provided in front of the opening 101, the cylinder 2 is provided on the bracket 6, the front end of the push rod of the cylinder 2 is connected to the motion shaft 3 and can drive it to move forward and backward, the valve plate 4 is fixed on the motion shaft 3 by welding, the valve plate 4 is against the opening 101, and the forward and backward movement of the motion shaft 3 can make the valve plate 4 contact or separate with the opening 101, the incinerator 1 is provided with a first guide mechanism 5, which plays a role of supporting and guiding the motion shaft 3. The first guide mechanism 5 includes a base 501 and three guide wheels 502 arranged on the base 501 along the circumferential direction. The base 501 is fixedly arranged on the incinerator 1. The motion shaft 3 passes through the centers of the three guide wheels 502 and is rollingly connected with the three guide wheels 502. The three guide wheels 502 are evenly arranged along the circumferential direction to enhance the wrapping performance of the guide wheels 502 and prevent the motion shaft 3 from deviating during the movement.
[0017] The base 501 is fixedly arranged at the center of the opening 101 on the incinerator 1, so that the valve plate 4 is in closer contact with the opening 101. When the moving shaft 3 moves, the valve plate 4 is driven to reach the opening 101. Since the base 501 is arranged at the center of the opening 101, the pressure distribution around the contact position of the valve plate 4 with the opening 101 is more uniform, thereby ensuring the sealing performance and preventing leakage.
[0018] The bracket 6 is provided with a second guide mechanism 7 , and the motion shaft 3 passes through the second guide mechanism 7 and the first guide mechanism 5 in sequence, playing an auxiliary guiding role and improving the stability of the motion shaft 3 during operation.
[0019] Working principle: When closing the opening 101, the push rod of the control cylinder 2 is extended to drive the moving shaft 3 to move. Under the support and guidance of the first guide mechanism 5, the valve plate 4 on the moving shaft 3 is pushed against the opening 101 to seal it; when the opening 101 needs to be opened, the push rod of the control cylinder 2 is retracted to control the valve plate 4 to move away from the opening 101.
[0020] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
