Description
Technical field
The present invention relates to the sealing structures in a kind of gas and oil separating plant, are used for suction and storing liquid more particularly to one kind
The sealing structure of body.
Background technique
Vacuum evacuation device, instrument for measuring gas content design and processing on, due to being differed with the air pressure of outside inside device
It is very big, and the accuracy in order to guarantee measurement, require that device has good air-tightness.It vacuumizes or the survey of air content
Amount, will form the environment of low pressure by the movement of actuator, should guarantee the formedness of sealing during this, also to guarantee
Movement is smoothly.
Most of product about the device, instrument for measuring gas content that vacuumize mostly uses complicated structure on the market now
Guarantee the reliability of sealing, and causes bulky, excessively heavy；Small part sealing performance is bad, leads to defect functionally.
Summary of the invention
The purpose of the present invention is to provide a kind of for suction and stores the sealing structure of liquid, is combined using static and dynamic sealing
Form, take many places to seal, ensure that the reliability and leakproofness of instrument for measuring gas content suction oil.
The technical solution adopted by the present invention is that:
The present invention include glass tube, piston, piston guide ring, piston seal, glass tube sealing ring, valve block sealing ring,
Valve block, gasket, glass tube protective cover and screw rod；Glass tube protective cover is cased with outside glass tube, one end of glass tube and glass tube are protected
One end inner hole of shield is tightly connected by glass tube sealing ring, and one end inner hole of glass tube protective cover and one end of valve block pass through
Valve block sealing ring be tightly connected, between one end end face of glass tube protective cover and one end end face of valve block be equipped with gasket, valve block it is another
One end centre bore is oil inlet B, and oil inlet B is radially provided with oil discharge outlet A, and piston is housed positioned at screw rod one end of glass tube hub,
Two slots on piston cylindrical surface and piston guide ring and piston seal are respectively provided between glass pipe orifice.
The piston seal, glass tube sealing ring, valve block sealing ring and gasket material are polytetrafluoroethylene (PTFE).
The piston guide ring and piston seal in two slots on the piston cylindrical surface, wherein piston guide ring is close
In the piston groove of screw rod side, and in piston groove of the piston seal far from screw rod side.
The invention has the advantages that:
The form that the present invention uses static and dynamic sealing to combine, takes many places to seal, and structure is simple, easy for installation, sealing element
Material corrosion resistance is strong, ensure that the reliability and leakproofness of instrument for measuring gas content suction oil.The present invention can apply vacuum means
It sets, in the sealing of instrument for measuring gas content.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
In figure: 1, glass tube, 2, piston, 3, piston guide ring, 4, piston seal, 5, glass tube sealing ring, 6, valve block

Specific embodiment
The present invention will be further explained below with reference to the attached drawings and specific examples.
As shown in Figure 1, the present invention includes including glass tube 1, piston 2, piston guide ring 3, piston seal 4, glass tube
Sealing ring 5, valve block sealing ring 6, valve block 7, gasket 8, glass tube protective cover 9 and screw rod 10；Glass tube protection is cased with outside glass tube 1
Cover 9, one end of glass tube 1 and one end inner hole of glass tube protective cover 9 are tightly connected by glass tube sealing ring 5, and glass tube is protected
One end of one end inner hole of shield 9 and valve block 7 is tightly connected by valve block sealing ring 6, one end end face of glass tube protective cover 9 and
Gasket 8 is housed, the other end centre bore of valve block 7 is oil inlet B between one end end face of valve block 7；Oil inlet B is radially provided with oil discharge outlet
A, 10 one end of screw rod positioned at 1 center of glass tube is equipped with piston 8, between 1 inner hole of two slots and glass tube on 2 cylindrical surface of piston
It is respectively provided with piston guide ring 3 and piston seal 4；7 inside of valve block is directly press-connected with glass tube 1, forms closed cavity.
The side for the instrument transmission case that the other end of glass tube 1 and the other end of glass shroud 9 are applied to mounted in the present invention
Face, the rotary nut connection in the other end and transmission case of lead screw 10.During the work time, oil discharge outlet A and oil inlet B are equipped with
Valve be in close state, under the drive of the transmission mechanism, screw rod 10 does reciprocating linear inside glass tube 1 with piston 8
Movement forms environment under low pressure and vacuumizes and Oil-gas Separation to realize.
Because piston 2 is slow in the intraluminal relative motion of glass, the sealing of glass chamber and piston 2 is all made of O-ring
Static seal form is aided with piston guide ring 3, protects glass 1；The sealing of glass tube 1 is divided at two, by glass tube 1 and valve block
7 extruding force prevents leakage of the oil liquid to two sides respectively, while using this installation sealing structure, is not only convenient for installing, simultaneously
Sealed reliable.
The piston seal 4, glass tube sealing ring 5, valve block sealing ring 6 and 8 material of gasket are preferably polytetrafluoro
The corrosion resistance of sealing element can be improved in ethylene.
The piston guide ring 3 and piston seal 4 in two slots on 2 cylindrical surface of piston, wherein piston guide ring 3
In 2 slot of piston of 10 side of screw rod, and piston seal 4 is far from 2 slot of piston of 10 side of screw rod.
Above-mentioned specific embodiment is used to illustrate the present invention, rather than limits the invention, of the invention
In spirit and scope of protection of the claims, to any modifications and changes that the present invention makes, protection model of the invention is both fallen within
It encloses.
