Description
Technical field
The present invention relates to assembly tool, and in particular to a kind of to fix its valve for the valve with wavy spring after installing valve seat
The instrument of seat.
Background technology
Valve is the control in the fluid delivery systems such as oil, chemical industry, long-distance transport pipes, various cryogenic engineerings and offshore oil production
Element, there is water conservancy diversion, block, adjust, throttling, preventing from flowing backwards, shunting or the function such as pressure release.Manual flat valve is sealed before valve to refer to close
The valve of vertical line direction moving switch of the closing member along path center line, is one of valve being most widely used at present.At present
Envelope manual flat valve demand is big before the upper valve of market, and production and the efficiency of assembling for improving valve are imperative.Sealed before valve flat manually
Plate valve is in assembling process, due to the effect of wavy spring elastic force between valve seat and valve body so that the spacing between two valve seats is small
In the thickness of valve plate, valve plate is difficult smooth and is accurately attached to valve inner（Between two valve seats）, it is therefore desirable to design one
Kind can facilitate valve site to assemble, the instrument for valve installation fixed valve base.
The content of the invention
It is an object of the invention to：A kind of convenience, instrument that is reliable, being efficiently used for valve installation fixed valve base are provided,
The instrument self structure is simple, while and can ensures to be easily understood when in use, easy to operate, so as to greatly improve the dress of valve
With efficiency.
The present invention technical solution be：The instrument includes thumbscrew 1, pad lid 2, round nut 3, steel pipe 4, pull bar
5th, resilient sleeve 6 and cone 7, the threaded one end of pull bar 5 are connected to the center of cone 7, and cone 7 is inserted in resilient sleeve 6, steel pipe 4 one
End is connected with resilient sleeve 6, and round nut 3 is threaded onto on the external screw thread of steel pipe 4, and the other end of steel pipe 4 covers pad lid 2, pull bar 5 it is another
One end stretches out pad lid 2 and screws on thumbscrew 1, is monolithically fabricated instrument.
Wherein, resilient sleeve 6 carries out wire cutting to the left by cutting start line along center line.
Wherein, the cylindrical of resilient sleeve 6 sets boss.
The present invention has advantages below：1st, for the instrument during for fixed valve valve seat, use principle is popular easily
Understand, be easy to Fast Learning and the use of onsite application personnel, while valve plate can be fast and accurately installed on valve inner（Two valves
Between seat）, substantially increase the efficiency of assembling of valve；2nd, the instrument is made up of seven parts altogether, and self structure is simple, is made and is added
Work and itself is easy to assembly, while small in volume, are convenient for carrying, are easy to use of the valve erecting yard to the instrument；
3rd, the material of resilient sleeve is spring steel, and intensity is high, has preferable pliability and plasticity, under normal circumstances, fatigue limit and
Multicolored alloy elastic is suitable, and elasticity is preferably；4th, wing nut, pad lid, round nut, steel pipe, pull bar and cone carry out phosphorus
Change is handled, and is provided surface protection to metal parts, is prevented metal to be corroded to a certain degree, while plays antifriction lubrication, so as to
Substantially increase the service life of instrument.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Fig. 2 is resilient sleeve part drawing.
Fig. 3 is the specifically used method schematic diagram of the present invention.
In figure：1 thumbscrew, 2 pad lids, 3 round nuts, 4 steel pipes, 5 pull bars, 6 resilient sleeves, 7 cones.
Embodiment
The technical solution of the present invention is further illustrated below in conjunction with the accompanying drawings.
As shown in Figure 1-2, the instrument includes thumbscrew 1, pad lid 2, round nut 3, steel pipe 4, pull bar 5, the and of resilient sleeve 6
Cone 7, the threaded one end of pull bar 5 are connected to the center of cone 7, and cone 7 is inserted in resilient sleeve 6, the one end of steel pipe 4 and resilient sleeve 6
It is connected, round nut 3 is threaded onto on the external screw thread of steel pipe 4, and the other end of steel pipe 4 covers pad lid 2, and the other end of pull bar 5 stretches out pad
Piece lid 2 simultaneously screws on thumbscrew 1, is monolithically fabricated instrument.
Wherein, resilient sleeve 6 carries out wire cutting to the left by cutting start line along center line.
Wherein, the cylindrical of resilient sleeve 6 sets boss.
As shown in Fig. 2 during use, instrument is first stretched into valve internal by valve latus rectum（Step 1）, until in instrument
The boss of resilient sleeve is to valve seat groove position, now turn thumbscrew, due to cone and resilient sleeve, thumbscrew and pad lid
Between located lateral, while thumbscrew is in rotary moving to the left, cone is moved to the right, and cone is received on the inside of resilient sleeve
Contracting, resilient sleeve are strutted by cone, cylindrical increase；The boss of resilient sleeve is caught in valve seat neck（Step 2）, then by round nut to
Left side is in rotary moving, until round nut is in contact with flange face, now continues to screw round nut, due to resilient sleeve and valve seat, circle
Located lateral between nut and flange face, valve seat move to the right, until valve seat is bonded completely in the horizontal with valve body（Step
3）；Both sides valve seat carries out aforesaid operations, realizes reliable fixation of the valve seat in valve inner, so as to which valve plate smoothly and accurately be filled
Enter between the valve seat of valve inner two（Step 4）；, only need to be anti-in order by round nut and wing nut after valve plate installation is completed
Direction is rotated to original position（Round nut is first rotated, then rotates thumbscrew）, you can instrument is taken out.
