Ball valve is sampled.There is problems with when being sampled using ball valve：1st, when medium pressure liquid is higher in pipeline, by sampling
Valve is difficult coutroi velocity, is easily caused static focus, causes unsafe factor.Without standard measure when the 2nd, sampling, completely with operator
Member's experience, sampling amount is controlled by frequent control valve aperture, is easily caused the phenomenon of evaporating, emitting, dripping or leaking of liquid or gas or excessive sampling, causes dirt
Dye is wasted.
The content of the invention
The purpose of this utility model is to propose a kind of traditional sampling control method of improvement, accomplishes quantitative, anti-overflow sampling, is kept away
Exempt from evaporating, emitting, dripping or leaking of liquid or gas and excessive sampling, reduce pollution and the liquid quantitative sampling anti-overflow valve for wasting.
What the purpose of this utility model was realized in：Liquid quantitative samples anti-overflow valve, including by transverse tube and vertical tube group
Into probe tube, transverse tube and vertical tube intersection be provided with the middle part of valve handle link valve plug, set in the probe tube after valve plug
Sensing valve is equipped with, the sensing valve is communicated with probe tube, and sensing valve bottom is connected with the wireway being arranged in vertical tube,
Connecting place capping has soft diaphragm, and diaphragm axle is provided with diaphragm, and the Inductance valve linked with valve handle rear portion is set in sensing valve
Core, is provided with to clamp the spacing decorative pearl on top of an official cap of diaphragm axle in sensing valve element bottom.
Due to carrying out such scheme, the application overcomes traditional sample cock and cannot automatically control the problem of sampling amount, keeps away
The evaporating, emitting, dripping or leaking of liquid or gas that is caused in sampling process and excessive sampling phenomenon are exempted from, realization fast and safely samples operation, reduces workman's work
Intensity, strengthens the security of operation process, significantly improves operating efficiency.

Specific embodiment
The utility model is not limited by following embodiments, can according to the technical solution of the utility model and actual conditions come
Determine specific embodiment.
Embodiment：As shown in Figure 1, 2, liquid quantitative sampling anti-overflow valve includes the probe tube 5 being made up of transverse tube and vertical tube,
Transverse tube and vertical tube intersection are provided with the valve plug 8 with the linkage of the middle part of valve handle 1, sensing is provided with the probe tube 5 after valve plug 8
Valve, the sensing valve is communicated with probe tube 5, and sensing valve bottom is connected with the wireway 6 being arranged in vertical tube, connecting place
Capping has soft diaphragm 7, and diaphragm axle 3 is provided with diaphragm 7, and the sensing valve element linked with the rear portion of valve handle 1 is set in sensing valve
9, it is provided with to clamp the spacing decorative pearl on top of an official cap 4 of diaphragm axle 3 in sensing valve element 9 bottom.
The external port of the wireway 6 is turned on extraneous.
The sensing valve includes sensing valve body 10, and sensing valve element 9 is located in sensing valve body 10, and sensing valve element 9 upper end is stretched
Go out to sense valve body 10 and the rear portion of valve handle 1 and live be connected, the work of the middle part of valve handle 1 is connected with push rod, the bottom of push rod 2 stretch into probe tube 5 and
Valve plug 8 is connected.
Spring base is provided with probe tube 5 under valve plug 8, back-moving spring is provided between spring base and valve plug 8.The valve
Plug 8 and spring base are electric conductor, electrostatic can be safely eliminated in time, to ensure sampling process safety.
Sensing valve element 9 bottom is provided with to place the decorative pearl on top of an official cap frame 12 of the spacing decorative pearl on top of an official cap 4, and the both sides of decorative pearl on top of an official cap frame 12 respectively set one
Decorative pearl on top of an official cap frame 12 is stretched out in the spacing decorative pearl on top of an official cap 4, the outside of the spacing decorative pearl on top of an official cap 4, and aforementioned films bobbin 3 is by stretching into sensing valve element 9 between the two spacing decorative pearls on top of an official cap 4
It is interior.
Sensing valve body 10 bottom is provided with the decorative pearl on top of an official cap groove 11 for accommodating the spacing exposure portion of the decorative pearl on top of an official cap 4.
During sampling, the vertical tube of probe tube 5 is goed deep into camshaft for sample, and the external port of wireway 6 is rested on into prepared sample volume
Liquid level at, push valve handle 1, push rod 2 by valve plug 8, open downwards by top, and the rear portion of valve handle 1 above carries, the spacing decorative pearl on top of an official cap 4 depart from decorative pearl on top of an official cap groove 11 by
Gradually clamp diaphragm axle 3 so that valve handle 1 cannot reset, valve plug is in normally open.Liquid is flowed into perpendicular by the sensed valve of transverse tube
Pipe, due to the suction effect of liquid stream, can make pressure sensitive valve inside produce negative pressure.Under normal operating conditions diaphragm about 7 air pressure it is basic
State in balance.After camshaft for sample liquid level rises to be covered and close 6 external port of wireway（Now sampling amount has reached preparation
Sample volume）, negative pressure understands rapid increase in pressure sensitive valve, and now the both sides air pressure of diaphragm 7 loses balance, and diaphragm 7 will drive film
Bobbin 3 to the lateral movement of negative pressure one, so as to the spacing decorative pearl on top of an official cap 4 be pushed downwards, while the rear portion of valve handle 1 is also in the presence of back-moving spring
Certain power is held down, so that the spacing decorative pearl on top of an official cap 4 loses fixed pivot effect, so that valve handle 1 is out of supply, while valve plug 8
In the presence of back-moving spring, self-styled closing motion was completed in 0.3 second, block runner between transverse tube and vertical tube.
Above technical characteristic constitutes most preferred embodiment of the present utility model, and it has stronger adaptability and optimal implementation
Effect, can according to actual needs increase and decrease inessential technical characteristic.
