The main differences between a faucet and a valve: technical features and functionality

[ad_1]

For spe­cial­ists work­ing in indus­tri­al enter­pris­es, it is impor­tant to know what are the dif­fer­ences between a valve and a gate valve.

general information

A valve is a dri­ve valve used for the man­u­fac­ture of a pipeline, where the gate valve rotates around its own axis in a per­pen­dic­u­lar direc­tion. The ele­ment has two com­po­nents:

  • Traf­fic jam;
  • Sta­t­ic body.
Fig 1. How the design works

A valve is a valve of a dri­ve type, where the struc­ture moves along the flow and enters the sad­dle. Designed for direct open­ing or clos­ing, reg­u­la­tion of the flow of any medi­um.

What are the main differences

It is cus­tom­ary to dis­tin­guish three types of fit­tings depend­ing on the pur­pose:

  1. Dri­ven.
  2. Reg­u­la­to­ry.
  3. Shut-off.

In some clas­si­fi­ca­tions, a guard group is added.

Con­sid­er­ing the main dif­fer­ences between a valve and a ball valve, it is worth not­ing that in the first mount, flu­id flow adjust­ment is per­mis­si­ble. The ball valve is not capa­ble of this task. Based on cur­rent reg­u­la­tions, it is strict­ly for­bid­den to con­trol and change the flow of flu­id using a ball valve by safe­ty reg­u­la­tions. First of all, this is jus­ti­fied by the lim­it­ed func­tions, since the traf­fic con­troller can only open or close the flow.

With the help of a valve, changes in the work­ing pres­sure are also allowed due to the pres­sure of water in the pipelines.

This is due to design dif­fer­ences that deter­mine the func­tions and use of ele­ments. Con­sid­er­ing the main ele­ments of the fixed body of the valve, the valve mech­a­nism “sits” on the sad­dle in it. Its move­ment is car­ried out in the direc­tion of flow.

Dur­ing the oper­a­tion of the crane, the turns are car­ried out around its own axis. If addi­tion­al ele­ments are need­ed, plumbers use ball ele­ments. When the ball starts to turn, the diam­e­ter in the hole auto­mat­i­cal­ly changes.

The valve is equipped with a bot­tom box. When screw­ing in / unscrew­ing the stems, the valve moves up and down.

Com­par­ing both designs, sev­er­al con­clu­sions can be drawn:

  1. The valve is in the closed and open posi­tions.
  2. The valve is also capa­ble of reg­u­lat­ing the pres­sure.
  3. To visu­al­ly rec­og­nize whether it is a valve or a faucet, just pay atten­tion to the han­dle. At the crane, its device is quite sim­ple, unlike the valve (here it is pre­sent­ed in the form of a lamb).

Con­sid­er­ing the main types of valves, it is rec­om­mend­ed to con­sid­er anoth­er pop­u­lar ele­ment — the valve.

There are sev­er­al types of cranes, based on the body of rota­tion:

  • con­i­cal. Visu­al­ly resem­bles the shape of a trun­cat­ed cone. The hole can be seen as a rec­tan­gu­lar or round shape. Most often used in gas sup­ply. Pop­u­lar due to cost.

  • Cylin­dri­cal. Chief con­troller of the heat­ing sys­tem. Can car­ry out ver­ti­cal move­ment to con­trol the flow of flu­id.
Fig 3. Cylin­dri­cal
  • Ball. No plumber can do with­out it. The hole is made in a round­ed shape through which the medi­um pass­es.

Why do you need a valve, the main advantages and nuances

A type of valve where the adjust­ment piece moves in a per­pen­dic­u­lar posi­tion, mov­ing in the direc­tion of flow. Among rep­re­sen­ta­tives of this cat­e­go­ry, the valve is con­sid­ered more rel­e­vant.

Fig 5. Gate valve

The tool is pop­u­lar in oper­a­tion:

  • Trans­port activ­i­ties, where the diam­e­ter of prod­ucts varies — 15–2000mm;
  • In the cre­ation of water and gas sup­ply;
  • In the field of hous­ing and com­mu­nal ser­vices;
  • Oil extrac­tion.

The preva­lence of the use of valves is due to the fol­low­ing aspects:

  • Easy to oper­ate;
  • Small size;
  • Oper­a­tion in var­i­ous con­di­tions is allowed;
  • There is lit­tle resis­tance in hydraulics.

The last aspect is impor­tant in the con­struc­tion of build­ing high­ways. Con­stant­ly car­ried out in an envi­ron­ment char­ac­ter­ized by high speed.

The mech­a­nism is not with­out seri­ous nuances. When choos­ing the nec­es­sary tools and mate­ri­als, experts do not rec­om­mend using designs where the spin­dle is retractable. The stroke at the shut­ter is at least one diam­e­ter.

It is cus­tom­ary to dis­tin­guish two types of valves:

  • Full bore.

Fig 7. Nar­rowed

The first is the most com­mon. In it, the full bore diam­e­ter is equal to the val­ue of the pipeline on which the tool is installed. To reduce the amount of torque, gate valves are used to con­trol valve con­trol, includ­ing reduc­ing the wear rate of oth­er pipeline com­po­nents.

There are sev­er­al prin­ci­ples of valve con­trol:

  • Man­u­al­ly;
  • By means of an elec­tric dri­ve sys­tem;
  • By means of a pneu­mat­ic dri­ve sys­tem;
  • Through a hydraulic sys­tem.

Con­sid­er­ing the com­par­a­tive char­ac­ter­is­tics between the valve and the valve, we can con­clude that both ele­ments have a num­ber of sim­i­lar fea­tures and dif­fer­ences.

Gen­er­al signs They are used to cre­ate tight­ness dur­ing the move­ment of the flow of liq­uid, gas in the pipeline. Ide­al for high pres­sure appli­ca­tions

What are the dif­fer­ences

The move­ment of the main ele­ment (par­ti­tion) is car­ried out in all direc­tions: to the right, to the left, up and down The shut­ter acts as the main ele­ment. It can move around its own axis, as well as place the chan­nel at a dif­fer­ent angle with respect to the flu­id flow
Wear is car­ried out inten­sive­ly with con­stant use Wears out less inten­sive­ly even with con­stant use
Addi­tion­al space needs to be cal­cu­lat­ed out­side of the pip­ing cre­ation to accom­mo­date part of the baf­fle It is nec­es­sary to cal­cu­late addi­tion­al space only for the place­ment of reg­u­la­to­ry ele­ments
In prac­tice, the instal­la­tion and oper­a­tion of the device is most often encoun­tered as a lock­ing ele­ment, in the open or closed posi­tion. As a reg­u­la­tor. At any time, it is enough to set the required inten­si­ty to ensure a uni­form flow
Rarely used as a con­stituent ele­ment in a mix­er Acts as one of the main ele­ments in the mix­er.

The faucet and valve are very tight. That is why plumbers use them dur­ing plumb­ing repairs. How­ev­er, the valve is char­ac­ter­ized by less wear and tear than that of valves. They can only be used longer if the fol­low­ing basic con­di­tions are met:

  • qual­i­ty reg­u­lar main­te­nance
  • opti­mal lubri­ca­tion.

Based on this table, we can con­clude that the main dif­fer­ences between the two mech­a­nisms can be traced in the fol­low­ing indi­ca­tors:

  1. How fast do parts wear out?
  2. The amount of free space that will be need­ed out­side of the pip­ing struc­ture.
  3. where it can be used.

The crane per­fect­ly copes with the role of a reg­u­la­tor, and can also act as an aux­il­iary ele­ment in reg­u­lat­ing the sup­ply of water or gas at high pres­sure. There­fore, when cre­at­ing a pipeline, often cranes are found at the end sec­tions. Since the rotat­ing ele­ment moves around its own axis, it does not require much space. But for reg­u­lat­ing mech­a­nisms, space will be required to posi­tion the valves.

A dis­tinc­tive char­ac­ter­is­tic of the mech­a­nisms is the type of the main mech­a­nism. It is a sys­tem that moves in a per­pen­dic­u­lar direc­tion in a pipeline. In the crane, a spe­cial shut­ter acts as the main ele­ment. If it is placed par­al­lel to the flow or at a slight angle, the inten­si­ty of the move­ment of the liq­uid or gas increas­es, with a per­pen­dic­u­lar arrange­ment, the inten­si­ty decreas­es.
