Adjustable plug valve based on chemical production

Abstract

The invention relates to the technical field of valves, and discloses an adjustable plug valve based on chemical production. The adjustable plug valve comprises a valve body, wherein a water inlet is formed in the outer surface of the side end of the valve body, a water outlet is formed in the side end of the water inlet, mounting plates are arranged at the side ends of the water inlet and the water outlet respectively, mounting holes are formed in the side ends of the mounting plates, a sealing layer is arranged at the side ends of the mounting holes, a first valve deck is arranged at the upper end of the valve body, a locking bolt is arranged at the upper end of the first valve deck, and a second valve deck is arranged at the lower end of the valve body. The adjustable plug valve based on chemical production is simple in structure and diversified in function, the connectivity is enhanced, the handle is convenient to mount and dismount, the plug valve can be folded and stored, space is saved, the wear resistance of the interior of the plug valve is enhanced, the plug valve is convenient to dismount, ceramic blocks on a valve seat are convenient to replace, the maintenance cost is reduced, the connection sealing performance is enhanced, the rotating stability of the valve element is improved, and usability is improved.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to an adjustable plug valve based on chemical production. Background technique [0002] The plug valve is a closing member or a plunger-shaped rotary valve. By rotating 90 degrees, the channel port on the valve plug communicates with or separates from the channel port on the valve body to realize opening or closing. The shape of its valve plug It can be cylindrical or conical. In the cylindrical valve plug, the channel is generally rectangular; in the conical valve plug, the channel is trapezoidal. These shapes make the structure of the plug valve light and suitable for cutting and connecting. It is suitable for medium passage and diversion, but it can also be used for throttling according to the applicable properties and the erosion resistance of the sealing surface. The existing plug valves have certain disadvantages when used. First, the handle length of the manual plug valve is l...

Problems solved by technology

[0002] The plug valve is a closing member or a plunger-shaped rotary valve. By rotating 90 degrees, the channel port on the valve plug communicates with or separates from the channel port on the valve body to realize opening or closing. The shape of its valve plug It can be cylindrical or conical. In the cylindrical valve plug, the channel is generally rectangular; in the conical valve plug, the channel is trapezoidal. These shapes make the structure of the plug valve light and suitable for cutting and connecting. It is suitable for medium passage and diversion, but depending on the applicable properties and the erosion resistance of the sealing surface, sometimes it can also be used for throttling. There are certain disadvantages in the use of existing plug valves. First, the handle length of manual plug valves is longer. It needs to take up a lot of space, which affects the installation of other valve bodies or pipelines, and it is easy to be accidentally touched by external force, which will cause the cock to deflect and cause the situation in the fluid channel to be changed. Secondly, the cock valve has poor wear resistance, such as the fluid contains powder impurity particles , will reduce the service life of the plug valve, and the valve seat needs to be replaced as a whole after wear, and the maintenance cost is high. Finally, when the valve is in use, the connection between the external pipe and the valve body and the connection between the internal valve core and the valve body are sealed. Poor performance, resulting in easy leakage of liquid, causing losses to the entire plant
