In order to achieve the uniformity of glue application, a lot of natural on-site glue application materials are used, and on-site control components are fully pasted by glue materials, so that the service lives of a plurality of components are short, the failure rate is high, a one-way throttle valve for adjusting the lifting and closing and pressurizing speed of a glue applying press roller is one of the components, the components are used when the glue applying press roller is replaced every time, the components are basically used once every 45 days, and the glue applying press roller causes the following troubles due to the corrosion of the glue materials:
1. because the raw material of the one-way throttle valve is cast iron, the corrosion of the sizing material is easy, and the adjustment of the full grain of the adjusting part is difficult.
2. Due to sizing and pressing sizing materials, the locking part of the one-way throttle valve is seriously corroded and the shell falls off because the sizing materials are frequently washed by strong alkali.
3. Spare parts are high in loss, and basically, a batch of spare parts are replaced every half year due to corrosion, so that the cost consumption is high.
Meanwhile, when the one-way throttle valve is used in a working environment with high risk of corrosion, the problem that the anti-corrosion cover is troublesome to take when being adjusted frequently exists; meanwhile, the anti-corrosion cover body is not taken down to operate and adjust the one-way throttle valve, and a series of problems of low adjustment precision, inconvenient treatment of corrosive liquid and sealing property also exist.
Disclosure of Invention
The invention aims to solve the problems, and provides an anti-corrosion one-way throttle valve which can carry out comprehensive and reliable anti-corrosion protection on the one-way throttle valve and simultaneously ensure the operation precision of the one-way throttle valve under the condition of not taking off an anti-corrosion cover body; and further improve the corrosion-resistant sealing performance and the service life of the device.
In order to realize the purpose, the invention adopts the technical scheme that: an anti-corrosion one-way throttle valve comprises a valve body, an inlet, an outlet and a regulating pipe; an adjusting rod is arranged in the adjusting pipe, a locking nut is arranged at one end of the adjusting rod, which is positioned outside the adjusting pipe, and an anti-corrosion cover body is sleeved on the adjusting pipe; the opening of the anti-corrosion cover body is provided with a sealing hoop device, the sealing hoop device comprises a hoop which is in a circular ring shape and is sleeved on the opening end of the anti-corrosion cover body, and one end of the hoop is provided with an opening and is provided with a fastening bolt structure; the tail end of the anti-corrosion cover body is closed and is provided with an inwards-concave top edge; scales are arranged on the adjusting pipe; an edge groove is formed on the top edge of the inner concave; the side grooves are evenly distributed on the bottom surface of the tail end of the anti-corrosion cover body at intervals, and the number of the side grooves is four.
Furthermore, convex edges are arranged on the inner wall and the outer wall of the anti-corrosion cover body at positions corresponding to the locking nuts.
Furthermore, the hoop is coated with a marking coating layer with bright color on one side close to the adjusting pipe.
Furthermore, the anti-corrosion cover body is a polytetrafluoroethylene cover pipe.
The invention has the beneficial effects that:
1. the device can avoid the corrosion damage to the valve body adjusting rod and the locking nut under the working environment with high corrosion risk by sleeving the anti-corrosion cover body on the adjusting pipe; meanwhile, the sealing hoop device ensures complete sealing after adjustment; finally, the operator can be helped to know whether the length of the internal adjusting rod exceeds the standard or not through the concave top edge so as to influence the adjusting precision.
2. The device ensures the operation precision of the one-way throttle valve under the condition of not taking off the anti-corrosion cover body by arranging the convex edge corresponding to the locking nut; the frequency of replacing the anti-corrosion cover body is reduced, and meanwhile, the stability and the reliability of the functions of the one-way throttle valve are ensured.
3. The device is provided with an edge groove on the concave top edge. It is used to lie in when the accumulation has corrosive liquid on the indent topside, can carry out instant and quick evacuation to it, avoids corroding the hydrops and influences the life of device.
4. The lower edge of the hoop in the device is provided with the marking coating which is bright in color and easy to distinguish, and can help workers to more conveniently compare the lower edge of the cover body with the scale on the adjusting pipe, so that the adjustment is more efficient and reliable.
