Abstract
The utility model discloses a balanced valve for protecting explosion -proof pressure transmitter, draw the platen press orchid including valve body, blow -down valve jam pole and T shape, install valve body one side the platen press orchid is drawn to T shape, T shape is drawn platen press orchid one side and is installed and draw the pressure mouth, draw pressure mouth one side and install lock nut, blow -down valve gland nut is installed to the valve body opposite side, blow -down valve gland nut installs one side the blow -down valve blocks up the pole, the flange is installed to the both sides of valve body. Beneficial effect lies in: discharging in too big pressure accessible valve body both sides, prevents that too big pressure from applying inside pressure transmitter, damages pressure transmitter.
Description
Technical field
This utility model relates to transmitter field, is specifically related to a kind of balance for protecting explosion-proof pressure transmitter
Valve.
Background technology
Pressure transmitter can will act at the pressure on its surface and be converted into the signal of telecommunication, is transferred on electronic equipment.Work as effect
When pressure on pressure transmitter is excessive, the DTU within pressure transmitter can be caused damage, make data without
Method shows.And common air bleeding valve can only pass through single-chamber aerofluxus, and excessive pressure quickly cannot be discharged from single-chamber, build-up of pressure
Extrude in air bleeding valve, thus cause pressure transmitter internal pressure moment to increase so that the numerical value moment of pressure transmitter increases
Add, cause measurement error.
Utility model content
The purpose of this utility model is that provides a kind of for protecting explosion-proof pressure pick-up to solve the problems referred to above
The balanced valve of device.
This utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of for protecting the balanced valve of explosion-proof pressure transmitter, including valve body, drain valve bott stick and T-shaped impulse method
Orchid, described valve body side is provided with described T-shaped impulse flange, and described T-shaped impulse flange side is provided with pressure-inducing nozzle, described impulse
Mouth side is provided with locking nut, and described valve body opposite side is provided with drain valve clamp nut, described drain valve clamp nut one
Side is provided with described drain valve bott stick, and the both sides of described housing are provided with flange.
In said structure, by described a kind of for protecting the balanced valve of explosion-proof pressure transmitter to be arranged on explosion-proof pressure pick-up
