Safety of automated industrial valves in operating conditions
Kryštof, Ondřej ; Trávníček, Petr (referee) ; Kotek, Luboš (advisor)
Choosing suitable and safe valve with accessories depends on general specifications for plant. Using valve for on/off, throttling, back-flow prevention, etc., pressure drop is related with Kv value or leakages from piping systems are main factors for properly valve selection. Valve have to resist chemicals and substances that may change the state, temperature and its fluctuation, pressure, corrosion and erosion. This properties determine pressure class, temperature resistance, connection into pipe and sealing material as gland packing, seats, seal between flange etc. This and other specification, listed in this thesis, can help determine suitable type of valve. This thesis deals construction design of valve and accessories as well. The last chapters are focused on calculation of safety valve and selection safe and appropriate control valve with accessories.

Water supply of scout camp by hydraulic ram
Růžička, Jakub ; Duchan, David (referee) ; Špano, Miroslav (advisor)
This work is dealing with water supply of a scout camp from Trusovický potok. The water is pumped with a ram pump to the water tank. The construction of the ram pump is simplified and it is collected from commonly available fittings and fixtures. The water from the tank is distributed by pipe network gravitationaly. Operating charakteristics of the hydraulic ram pump were measured in the laboratory.

Technological Solution of the Rough Superstructure of the Municipal House U Muchů
Bystričan, Daniel ; Porwisz, Ondřej (referee) ; Mohapl, Martin (advisor)
The main goal of my bachelor's thesis is the construction-technological solution of the rough superstructure of the Municipal House U Muchů, which is located in the village of Dolní Město near the larger town of Humpolec in Vysočina. This work contains a technical report for the given technological stage, the situation of the construction with wider relations of transport routes, a statement of dimensions for the technological stage, a technological regulation including a balance of resources (item budget together with a graph of the deployment of workers). Furthermore, the content of this work is a drawing of the construction site equipment together with a technical report and construction organization solution for the rough superstructure, a timetable for the given stage, a design of the machine assembly including a comparison of two variants and the selection of the most suitable machine, control and test plans and ensuring work safety. In the last point of this work, I am dedicated to verifying the adhesion and load-bearing capacity of the connecting material, more specifically, it is a polyurethane adhesive for masonry.

Determination of closing valve control moments
Benda, David ; Vosynek, Petr (referee) ; Hnízdil, Milan (advisor)
This bachelor thesis deals with the calculation of the torque on the output shaft of the four-concentric butterfly valves and experimental measurement of this torque on real manufactured valves. At the beginning is carried out a brief research, the purpose describe the basic components of the butterfly valves, its production variants of the offset disc, eventually types of fittings to piping. The main part describes the partial torque occurring on the individual components. Following data from the performer measurement and at the end are compared obtained results.

Heating of multifunkcional building
Kořenková, Veronika ; Formánek, Marian (referee) ; Počinková, Marcela (advisor)
The goal of this bachelor thesis is to introduce a heating system solution for multifunctional building. Thesis is divided into theroretical, calculation and project parts. Theoretical part is focused on the definition of fittings in heating systems. Second part depict the proposal of heating system and heat preparation of the multifunctional building, which contains veterinary clinic and housing units. Gas condensing boiler is chosen as a source of heat. The building is heated by steel panel radiators and towel rail radiators. Preparation of hot water is done by two indirect heating water storage tanks. Preheating of water is supported by solar collectors. Project part of the thesis contains technical report and drawing, based on the calculation part.

Fittings of heating systems
Klus, Lukáš ; Adam, Pavel (referee) ; Počinková, Marcela (advisor)
The theme of this diploma thesis is fittings of heating systems and it is divided into three parts. The first part deals with this topic on theoretical level. In the second part, there is a calculations and drawings that deals with heating and water heating of the apartment building in Uherské Hradiště. This part is solved in two variants concerning hydraulic balancing and regulation of the heating system. The last part of the thesis is an experimental solution and processing of pressure loss results of selected valves. These results are compared with the values reported by the manufactures of the valve.

Pressure loss valves in heating systems
Náglová, Michaela ; Adam, Pavel (referee) ; Počinková, Marcela (advisor)
The theoretical part of the thesis deals with the hydraulics of heating systems. The aim of the project is a design of the heating and hot water preparation system for an apartment building. The building has 6 above-ground floors and 2 underground floors. Two different options of heating systems were designed, comparison and results are presented in the thesis. In the first case the heat source during the winter season and for water heating, where chosen two gas condensing boilers, situated in separated room on the second underground floor. In the second case, each apartment has its own gas condensing boiler. The experimental part of the project deals with measurements of pressure losses in water armatures used in heating systems. The aim of this part is the determination of coefficients of added resistance for uncontrolled elements, which are normally presented as tabular value. In thesis are presented results for a ball valve, backflow preventer, filter, for slide valve and thermostatic valve. Measurements for thermostatic valve where done with different settings and results are compared with parameters listed in the datasheet.

Design and lay-out of high pressure pumping station.
Václavík, Tomáš ; Franc, Zdeněk (referee) ; Habán, Vladimír (advisor)
The aim of diploma thesis is design and lay-out of high pressure pumping station with plunger pumps for splash of scales from slabs of hot-rolled. Theoretic (introduction) part of this thesis contain description of formation of scales and description of ways how it is possible remove these scales. And this part contains also explication of effect of water jet on solid material. The practical part of diploma thesis is focused on design of pumping station including of dimensioning of machinery. Part of this work is also technical documentation for proposed pumping station and specification of main machines and devices.
