ABSTRACT
It is impossible to imagine life without an elevator in tall buildings and structures. Although the elevator serves for quick and convenient access of people to each apartment, compliance with safety rules during their operation is considered one of the important factors. Smoothness and trouble-free operation of elevator installations are one of the main factors in ensuring the comfort and health of people. In the former USSR, an important requirement in the design of buildings above 5 floors was considered to consider the issue of providing an elevator.
Keywords: Elevator, multi-storey buildings, speed of movement, load capacity.

ABSTRACT
In the modern era, one of the main issues of oil and gas exploitation is the design and implementation of wear-resistant equipment. The importance of the issue lies in the fact that the exploited oil product consists of hydrocarbon compounds, sand, sulfur, etc. In addition, additives in the composition of oils accelerate corrosion, abrasive corrosion and other processes in the equipment used.
Currently, the main oil production in Azerbaijan is carried out in offshore fields. Along with the above processes, sea water, the environment (atmospheric phenomena) have a serious impact on the durability of equipment.
Among the equipment used in oil production and transportation, throttles are of particular importance. During operation, the throttle valve on the left side of the incoming fluid exerts high pressure at high speed at an angle of 90°. At the same time, the liquid enters the upper landing hole, at this time the end part does not open completely. The tip presses on the top of the part. This part is the lower part of the nut. At this time, it is subject to wear under the influence of oil in this part. The pressure of the incoming liquid leads to the destruction of this part.
Keywords: adjustable throttle valve, seat, end part, fountain fitting, tightness.
