Connection.
Further, two triple valves are " L " type triple valve.
Further, balance pipe is provided with two, and one end of two balance pipes is connect with sampling bottle holder 8 respectively, the other end
It is connect respectively with the second interface of two triple valves.
Further, the spool of two triple valves is oppositely arranged, and the connecting rod is fixedly connected with the spool, is driven
The connecting rod rotation is moved, and then drives valve core rotation.
Further, the handle is vertically arranged with the connecting rod.
Further, two of the fluid reservoir, which are open, is separately positioned on the top and bottom of tank body.
Further, there is scale on sampling bottle.
The utility model obtain the utility model has the advantages that
(1) internal and external pressure balance principle has cleverly been used, the liquid in equipment can be sampled online, operation side
Just, sample rate is fast, without shutting down to equipment.
(2) liquid in fluid reservoir is the liquid under equipment running status, and sample detection error is small, and reference value is high.
(3) it can be sampled according to actual needs, in addition, sampling process No leakage, no pollution to the environment.

Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, with reference to the accompanying drawing and implement
Example is described in further detail the utility model.It should be appreciated that specific embodiment described herein is only to explain this reality
With novel, it is not used to limit the utility model.
One kind of the utility model is online without pressure sampling valve, as shown in Figure 1-3, include 1, two triple valve 2 of bracket, connect
Bar 3, handle 4, fluid reservoir 5, balance pipe 6, adapter 7, sampling bottle holder 8 and sampling bottle 9, two triple valves 2 are fixed on bracket 1
On, two openings of fluid reservoir 5 are connect with the first interface 21 of two triple valves 2 respectively, and sampling bottle 9 are divided by balance pipe 6
It is not connect with the second interface 22 of two triple valves 2, in the equipment that the access of third interface 23 of two triple valves 2 needs to sample,
Sampling bottle 9 is tightly connected by adapter 7 and sampling bottle holder 8, the movement of 4 drive connection bar 3 of handle, and then synchronously control two three
Port valve 2 acts, and the first interface 21 of triple valve 2 is connected to third interface 23 or first connects 21 mouthfuls and connect with second interface 22
It is logical.
In one embodiment, two triple valves are " L " type triple valve.
In one embodiment, balance pipe 6 is provided with two, and one end of two balance pipes 6 is connect with sampling bottle holder 8 respectively,
The other end is connect with the second interface 22 of two triple valves 2 respectively.
In one embodiment, the spool of two triple valves 2 is oppositely arranged, and connecting rod 3 is fixedly connected with spool, is drivingly connected
Bar 3 rotates, and then drives valve core rotation.
In one embodiment, handle 4 is vertically arranged with connecting rod 3.
