Abstract
The invention relates to a three-valve set, and belongs to the technical field of pressure detection. The three-valve set comprises a high-pressure side stop valve, low-pressure side stop valves, a balance valve and a valve body; the high-pressure side stop valve is arranged on the left side of the valve body, and the low-pressure side stop valves are arranged on the right side and at the upper part; the valve body is provided with a first connecting port and a second connecting port; an internal thread is arranged in the first connecting port; the first connecting port is connected with a first adapter; an external thread is arranged on one side of the first adapter; a first O-shaped rubber ring is arranged between the first connecting port and the first adapter; the second connecting port is connected with a second adapter and a second O-shaped rubber ring; and the second adapter has the same structure with the first adapter. As adapter rings are arranged in joints of the three-valve set, the three-valve set becomes an independent valve, and can connect with differential pressure transmitters with different brands and model numbers, the production cost is reduced, and workers are convenient to operate.
Description
Technical field
The present invention relates to a kind of three valve group, and in particular to a kind of three valve groups for differential pressure transmitter, belong to pressure detecting
Technical field.
Background technology
Differential pressure transmitter is the transmitter of the difference of measuring transducer pressure at two ends, outputting standard signal（As 4 ~ 20mA, 0 ~
5V）.Differential pressure transmitter from unlike general pressure transmitter they have 2 pressure interfaces, differential pressure transmitter typically divides
For positive pressure side and negative pressure end, generally, the pressure of the positive pressure side of differential pressure transmitter should be greater than negative pressure section pressure and could measure.
When differential pressure transmitter is used to detect, as during its start and stop, transmitter two ends pressure reduction can exceed that the highest of pipe meets
Pressure reduction, causes damage, it is therefore desirable to adopt valve group to be adjusted pressure to ensure the normal operation of equipment in start and stop, commonly uses
Regulation valve group be three valve groups.
Three valve groups be by three three valve groups communicated with each other into.According to each valve, role can be divided in systems
For：The left side is high pressure valve, and the right is low pressure valve, and middle is balanced valve.Three valve groups with difference transmitter support the use, effect be by
Positive and negative pressure measuring chamber is turned on or off with impulse point；Or positive/negative-pressure measuring chamber is disconnected or turned on, concrete principle is as shown in Figure 1.
As differential pressure transmitter model is respectively had any different, the interface size of pipeline is also different, typically in differential pressure transmitter
Three supporting valve groups can be all provided during purchase.But three valve groups are conventional components, so increased production cost；Meanwhile,
Measurement is caused also to be annoying staff because three valve group interface problems can not carry out matching with differential pressure transmitter.
The content of the invention
It is an object of the invention to overcome above-mentioned weak point, there is provided a kind of possessing universal models interface, for differential pressure
Three valve groups of transmitter.
According to the technical scheme that the present invention is provided, three valve groups, including high pressure survey stop valve, low-pressure side stop valve, balanced valve
And valve body, high pressure being provided with the left of valve body and surveys stop valve, right side is provided with low-pressure side stop valve, and top is provided with low-pressure side stop valve；
The valve body is provided with the first connector and the second connector；Be provided with female thread in first connector, the first connector with
First adaptor connects, and the first adaptor side is provided with external screw thread, an O is additionally provided between the first connector and the first adaptor
Type rubber ring；Second connector is connected with the second adaptor and the second O-shaped rubber ring；The structure of the second adaptor and the first switching
It is identical.
If first adaptor includes adapter ring of the dried layer by the threaded connection of inside and outside matching；It is same on second adaptor
If sample includes dried layer adapter ring.The connecting tube of the adapter ring correspondence different model differential pressure transmitter.
If female thread being equipped with inside the dried layer adapter ring, and diameter being homogeneous at the screw thread of every layer of connection ring connection
Together so that if dried layer connection ring can be taken as needed.
The connecting tube of the adapter ring correspondence different model differential pressure transmitter.
Beneficial effects of the present invention：The present invention arranges adapter ring by the seam to three valve groups so that three valve groups become
Independent part, can connect the differential pressure transmitter of different brands model, reduce production cost, facilitate staff behaviour
Make.

Specific embodiment
As Figure 2-3：Three valve groups, including high pressure survey stop valve 1, low-pressure side stop valve 2, balanced valve 3 and valve body 4,
High pressure is provided with the left of valve body 4 and surveys stop valve 1, right side is provided with low-pressure side stop valve 2, and top is provided with low-pressure side stop valve 2；
The valve body 4 is provided with the first connector 5 and the second connector 6；Female thread, the first connection are provided with first connector 5
Mouth 5 is connected with the first adaptor 7, and 7 side of the first adaptor is provided with external screw thread, between the first connector 5 and the first adaptor 7 also
It is provided with the first O-shaped rubber ring 8；Second connector 6 is connected with the second adaptor 9 and the second O-shaped rubber ring 10；Second adaptor 9
Structure it is identical with the first adaptor 7.
If first adaptor 7 includes adapter ring 11 of the dried layer by the threaded connection of inside and outside matching；Second adaptor 8
If upper equally include dried layer adapter ring 11.
If female thread being equipped with inside the dried layer adapter ring 11, and diameter being equal at the screw thread of every layer of connection of connection ring 11
It is identical so that if dried layer connection ring 11 can be taken as needed.
The connecting tube of 11 corresponding different model differential pressure transmitter of the adapter ring.
During present invention work, due to adapter ring 11 and existing several Traditional differential pressure transmitter connecting tube model on market
It is similar, it is only necessary to select suitable connection ring 11, unnecessary connection ring 11 is removed, subsequently by the connection ring of matching by differential pressure
Transmitter is connected with three valve group of the invention, by high pressure survey stop valve 1, low-pressure side stop valve 2, balanced valve 3 adjustment i.e. can be with
The start and stop step for completing differential pressure transmitter of safety, improves the utilization rate of three valve groups, reduce the production of differential pressure transmitter into
This.
