Abstract
The utility model relates to a multi-point pressure circuit detecting valve, which is a device making use of a sensor for the circuit detection of the multi-point pressure and is composed of two plates of a plate and a B plate, wherein, the A plate is provided with multiple pressure measuring eduction tubes (2), and the corresponding position of the B plate is provided with a plunger type valve (3). The A plate or B plate is provided with a pressure transferring eduction tube (11) which is connected with a pressure sensor (1). A common valve cavity (7) is arranged between two plates. The hydraulic principle can be made use of for starting and stopping each valve by the form of the circuit for transferring pressure on each point to the sensor. Then the pressing quantity is changed into electricity quantity and is sent to a digital voltmeter with direct current or a data acquisition system for conducting the data acquisition and processing. The device can normally work under one positive-negative atmosphere pressure.
Description
The utility model relates to a kind of new device of fluid engineering test.
The pressure distribution that measures on the solid boundary when carrying out the fluid engineering test is an important content measurement.Adopting glass tube pressure measurement row to survey at present mostly reads.Air in this method connecting pipe is difficult for draining, work efficiency is low, can not adopt computer technology to carry out data acquisition.Release the pressure scanning valve for addressing this problem U.S. SCANIVALVE company.This device is made up of rotor and stator.On stator, there are 48 pressure taps to join with thin plastic pipe and measured point.A pressure tap is arranged on rotor, and its passage joins by axle center and pressure transducer.Rotor switches one by one to measuring point, and pressure is sent in the sensor.Rotor and stator are by the smooth finish sealing of self.Therefore very high to requirement on machining accuracy, and sealing property is still relatively poor, can not measure wall pressure distribution under decompression state.
The purpose of this utility model provides a kind of convenient and reliable touring detected pressures or the device of water level.It can be under a positive and negative atmospheric pressure operate as normal, and join with microcomputer and to carry out data acquisition process, improve the reliability of work efficiency and data greatly.
The utility model is with the touring device that is communicated with a sensor separately of a plurality of piezometric tube.50 measuring points of this device are one group.When surpassing 50, the measuring point number can contact with two or more sets.
The purpose of this utility model is achieved in that this device is made up of A, B two plates.Dress pressure measurement fairlead (2) on the A plate, on the correspondence position of B plate, adorn plunger valve (3), adorning a pressure transmission fairlead (11) on A plate or B plate joins with sensor (1), one public valve pocket (7) is arranged between two plates, between plate and plate with seal pad (6), (10) sealing, between valve pocket (9) and B plate with O-ring seal (8) sealing, with pressure measurement fairlead (2) between use seal pad (6) to seal.Be full of detected fluid between A, B two plates, it is the medium that transmits pressure.The utility model is simple in structure, impermeability height, reliable operation.It is rubber that seal pad and O-ring seal adopt material.
Accompanying drawing 1 is the sectional view according to the data-logger that the utility model proposes.
Below in conjunction with accompanying drawing 1 explanation working condition of the present utility model.
When measuring certain measuring point pressure, rotate its corresponding bonnet (4), mobile valve (3), utilize hydraulic principle, thereby the pressure that makes this measuring point is sent in the sensor (1), then amount of pressure is converted into electric weight and sends in the D.C. voltmeter and to show or to join with data acquisition system (DAS) and carry out data acquisition and processing (DAP).Catching up with gas to be achieved in that joins a certain pressure measurement fairlead and high flush tank as catching up with tracheae.Opening simultaneously catches up with the valve of tracheae and the valve of measured point to catch up with gas to this measuring point.
Claims (2)
1, the touring pressure detection valve of a kind of multiple spot, form by two blocks of fixing plates of A, B, it is characterized in that dress pressure measurement fairlead (2) on the A plate, on the correspondence position of B plate, adorn plunger valve (3), adorning a pressure transmission fairlead (11) on A or B plate joins with sensor (1), one public valve pocket (7) is arranged between two plates, seal with seal pad (6), (10) between plate and plate, seal with O-ring seal (8) between valve pocket (9) and B plate, plunger valve (3) seals with O-ring seal (5) with valve pocket (9), seals with seal pad (6) with pressure measurement fairlead (2).
2, detection valve according to claim 1 is characterized in that it is rubber that seal pad and O-ring seal adopt material.
