Overview of Y-150 Y-200 Y-250 Pressure gauge

The pressure gauge refers to the elastic component as the sensitive component, the measurement and indicator of higher than the environmental pressure instrument, is very popular, it is almost throughout all industrial processes and scientific research fields. It can be seen everywhere in heat pipe network, oil and gas transmission, water and gas supply system, vehicle maintenance factories and shops. Especially in the process of industrial process control and technical measurement, the mechanical pressure gauge is more and more widely used because of its elastic sensitive element with high mechanical strength and convenient production.

Working priciple of Y-150 Y-200 Y-250 Pressure gauge

The pressure gauge transmits the pressure deformation to the pointer through the elastic deformation of the sensitive components (Bourdon tube, bellows, bellows) in the watch, and then causes the pointer to rotate to display the pressure.

Main structure of Y-150 Y-200 Y-250 Pressure gauge

Overflow hole: in case of emergency of bourdon tube bursting,

The internal pressure will be released to the outside through the overflow hole, preventing the glass panel from cracking. Note: In order to maintain the normal performance of the overflow hole, a space of at least 10mm should be set aside behind the table. The overflow hole cannot be modified or blocked.

Pointers: Pointers other than standard Pointers are optional.

Glass panel: in addition to standard glass, other special glass, such as reinforced glass, non reflective glass is also optional.

Performance classification: common type (standard), steam for common type (M), heat resistant type (H), vibration resistant type (V), steam for vibration resistant type (MV) heat resistant vibration resistant type (HV).

Treatment: no oil/no water treatment to remove residual water or oil in the liquid receiving part during manufacturing.

External specification: shell color should be specially indicated in addition to standard color.

Throttle valve (optional): To reduce pulsating pressure, the throttle valve is installed in the pressure inlet.

Features of Y-150 Y-200 Y-250 Pressure gauge

strong corrosion resistance

Stainless steel pressure gauge case and thread are made of authentic stainless steel material, so it can be used in corrosive environment when measuring corrosive liquids or gases, and will not be affected by the normal reading of the value will not damage the dial. In addition to the stainless steel dial glass is explosion-proof and anti-corrosion tempered glass, so the overall combination can make it in different corrosive environment can be used freely.

strength and hardness

Stainless steel pressure gauge has better strength and hardness, in use process can withstand the influence of various external load and not be destroyed, the more business users are willing to choose stainless steel pressure gauge, so shell use material made of stainless steel pressure gauge than aluminum or other material strength and hardness of the iron, Can ensure in the use process will not be affected by external force and damage dial.

high earthquake resistance

The stainless steel pressure gauge is made of stainless steel as well as the internal original, and the whole table is filled with silicone oil, which can make the pressure gauge play a good shock absorption and earthquake resistance. Therefore, in some special occasions, such as the mining site, you need to choose a good shockproof stainless steel pressure gauge, in order to achieve good precision pressure test.
