Background technology
Pressure unit refers to export the pressure transducer into standard signal, is a kind ofly to accept the instrument that pressure variations is converted to standard output signals in proportion.The physical pressure parameter such as gas, liquid that side pressing member sensor can be experienced by it changes the electric signal of standard into, carries out measuring, indicating and procedure regulation to supply the secondary instruments such as indicator alarm, registering instrument, regulator.Pressure unit is a kind of sensor the most conventional in industrial practice, it is widely used in various industrial automatic control environment, relates to numerous industries such as water conservancy and hydropower, railway traffic, intelligent building, production automatic control, Aero-Space, military project, petrochemical industry, oil well, electric power, boats and ships, lathe, pipeline.
Current pressure unit, when pressure is excessive, easily occurs that internal sensor diaphragm is impaired because of compression shock, affects measuring accuracy.And current pressure unit adopts multiple O type seal with elastometic washer core body, because the principal ingredient of O type rubber ring is rubber, rubber in high temperature environments volatile go out oxious component, at low ambient temperatures, material easily goes bad, and occurs contractingization phenomenon.Simultaneously because the media compatibility sex expression of rubber is bad, need to change different O type circles according to the difference of measuring media, change trouble.Therefore the seal with elastometic washer of O type is adopted, sealing is poor, cost is high, the problem occurring being corroded is easy to when being in oils and corrosive liquid environment for a long time, pressure unit inner seal member is easily caused to be shifted or distortion, allow by side fluid inflow pressure transmitter inner, cause electronic circuit board to be damaged, the accuracy that impact is measured.Whether in addition, before some occasion uses, need detected pressures transmitter sensitive, on-the-spot easy inspection method is: with the objects such as screwdriver direct press pressure transmitter core body, and the method easily to cause pressure unit core body to be stung bad.
Utility model content
The purpose of this utility model there is provided the two damping pressure transmitter of a kind of high withstand voltage binodal, adopt level 2 buffering structure, make pressure unit under the working environment of instantaneous pressure impact, measurement fluid flow instability, can steady pressure and flow effectively, pressure suffered by guarantee transmitter core body and the temperature of flow are within tolerance range, avoid inner diaphragm impaired because of compression shock, improve the stability of pressure unit and extend its serviceable life.Good in low temperature pressurization lower seal performance, avoid leaking, protective is good, is applicable to rugged environment.
The technical solution adopted in the utility model is as follows:
The two damping pressure transmitter of a kind of high withstand voltage binodal, comprise water joint, jiont treatment seat, housing, pressure unit core body, first pressure seat, first pulse buffer, second pressure seat and the second pulse buffer, described housing upper end connects water joint by jiont treatment seat, housing lower end connects the first pressure seat, first pressure seat is provided with pressure unit core body, pressure ring is provided with above described pressure unit core body, pressure unit core body lower end connects the first pulse buffer by fluid hose, circular gasket is provided with between pressure unit core body and fluid hose, the periphery of circular gasket is evenly equipped with through hole, described first pulse buffer connects the second pulse buffer, second pulse buffer is arranged on the second pressure seat, glassy layer is provided with between described first pressure seat and the second pressure seat.
Described housing upper end and jiont treatment seat are welded to connect, and jiont treatment seat and water joint are threaded connection.
Described glassy layer is the glass material obtained after sintering.
Compared with the prior art, the beneficial effects of the utility model are as follows:
The two damping pressure transmitter of height of the present utility model is withstand voltage binodal, adopt level 2 buffering structure, make pressure unit under the working environment of instantaneous pressure impact, measurement fluid flow instability, can steady pressure and flow effectively, pressure suffered by guarantee transmitter core body and the temperature of flow are within tolerance range, avoid inner diaphragm impaired because of compression shock, improve the barotolerance of pressure unit; Be provided with pressure ring above described pressure unit core body, pressure ring can make transformer core body position fix, and strengthens its vibration resistance; Circular gasket is provided with between described pressure unit core body and fluid hose, the periphery of circular gasket is evenly equipped with through hole, arranging of circular gasket can slow down the fashionable pressure unit core body vibrations caused of tested pressure medium flow, protective is good, can stop sharp instruments such as screwdrivers, prevent pressure unit core body from being stung bad, extend the serviceable life of transmitter, what through hole guarantee liquid pressure was reliable, sensitive passes to pressure unit core body; Glassy layer is provided with between described first pressure seat and the second pressure seat, employing glassy layer is bonding, bonding force is much larger than the pressure be subject to when adopting O type circle to make seal, strength of joint is safe and reliable, improve the withstand voltage and compressive strength of pressure unit, simultaneously, glass is a kind of nonmetallic materials, there is higher softening point temperature, and it can not discharge any oxious component when using in hot environment, under low-temperature condition state, chemistry, physical characteristics are stablized, there is very strong anticorrosion, be applicable to rugged environment.
