Description
Technical field
The utility model is related to equipment technical field, specially a kind of to seal safe bellows connection valve.
Background technology
At present, bellows is widely used in instrument and meter, is mainly used for as the measuring cell of pressure measuring instruments,
Convert pressure into displacement or power.Ripple tube wall is relatively thin, and sensitivity is higher, and measurement range is tens of handkerchiefs to tens of MPas.It is living
Moved end directly indicates the size of pressure by driving pointer.The bellows composition that usually combined with displacement transducer is output as electricity
The pressure sensor of amount, is also sometimes used as isolation element.
But existing bellows connection valve exist in use some shortcomings part, its be all mostly directly with
Bellows is connected, and is not provided with any sealing effectiveness auxiliary element well at link position, thus often lead to bellows with
Connection valve connection closely, does not cause the problems such as having spilling or leak, and causes the serious safety for wasting or even bringing many
Hidden danger.
Utility model content
The purpose of this utility model is to provide a kind of sealing safe bellows connection valve, to solve above-mentioned background
The connection valve proposed in technology is not provided with any auxiliary element with bellows junction, so as to cause connection not tight, and then band
The problems such as carrying out many potential safety hazards.
To achieve the above object, the utility model provides following technical scheme：It is a kind of to seal safe bellows company
Valve, including connection valve body and rubber cylinder are connect, one end of the connection valve body is installed with the first valve port, and connection valve
The other end of body is installed with the second valve port, and the 3rd valve port, described are installed with the top of the connection valve body
Internal thread is provided with the inside of three valve ports, and the nested inside of the 3rd valve port is provided with rubber baffle ring, the one of first valve port
Side is fixedly connected by linkage section with light bar segment, and one end of light bar segment is provided with bellows link slot, and the rubber cylinder is embedding
Set is provided with external screw thread installed in the inside of linkage section on the outside of linkage section.
Preferably, it is installed with protective case on the outside of the bellows link slot.
Preferably, it is connected with light bar segment at first valve port, the second valve port and the 3rd valve port.
Preferably, the rubber baffle ring is located at the lower section of internal thread.
Compared with prior art, the beneficial effects of the utility model are：A kind of safe bellows connection of sealing
Valve, first, on the basis of original, in junction by being provided with a baffle ring and a rubber cylinder so that kept off after installing connection
Ring is brought into close contact with cylinder, so as to ensure that there are enough sealings junction, solves traditional connection valve poor sealing
Problem；Secondly, the connecting rod that each valve port of the connection valve is connected is detachable, so that convenient each valve port problem to device
Solution and to the cleaning inside connection valve；Finally, connection valve is provided with a protective case with bellows junction, places bellows
Because caused by being split using connector too long internal liquid spray to machine and staff caused by danger.

Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of the utility model protection.
Refer to Fig. 1-3, a kind of embodiment that the utility model is provided：It is a kind of to seal safe bellows connection
Valve, including connection valve body 3 and rubber cylinder 12, the one end for connecting valve body 3 is installed with the first valve port 2, and connection valve
The other end of body 3 is installed with the second valve port 4, and the top for connecting valve body 3 is installed with the 3rd valve port 8, the 3rd valve
The inner side of mouth 8 is provided with internal thread 7, and the nested inside of the 3rd valve port 8 is provided with rubber baffle ring 6, and the side of the first valve port 2 leads to
Linkage section 10 is crossed to be fixedly connected with light bar segment 1, and one end of light bar segment 1 is provided with bellows link slot 5, rubber cylinder 12 is nested
The outside of the inside of linkage section 10, and linkage section 10 is provided with external screw thread 11, peace is fixed in the outside of bellows link slot 5
Equipped with protective case 9, it is connected with light bar segment 1 at the first valve port 2, the second valve port 4 and the 3rd valve port 8, rubber baffle ring 6 is located at interior spiral shell
