Description
Technical field:
A kind of mounting or dismounting tools for valve plate and valve seat of gate valve is used for the mounting or dismounting of petroleum gas well head device, well control equipment valve plate and valve seat of gate valve, belongs to the maintenance tool manufacturing technology field of gate valve on wellhead assembly, the well-control equipment.
Background technology:
In the prior art, what the valve plate and valve seat of gate valve mounting or dismounting that have wavy spring were adopted is that the scissors instrument is installed and removed, when implementing the valve plate and valve seat of gate valve mounting or dismounting, the pulling block of instrument front end need be put into the groove of valve seat could strain valve seat, thereby pack valve plate into, the shortcoming of prior art is: because the pulling block head is positioned at the front end that mounting or dismounting tools is cut arm, and the centre of gyration of cutting arm is in the middle part of cutting arm, so when cutting arm and open, the running orbit that is in the pulling block of cutting the arm front end can open according to circular trace, make and be in the pulling block of cutting the arm front end and be not easy very much in the groove of inserted valve seat, the insertion that needs repeated multiple times to carry out pulling block just can make draws the groove that enters valve seat soon, because friction is repeatedly used, the head of pulling block can become circular arc owing to wearing and tearing, the fast head that draws of circular arc makes operation more difficult, and after the head wearing and tearing of pulling block, entire tool is just only scrapped; In addition, the scissors instrument can only be strained the mounting or dismounting that valve seat carries out valve plate, and in valve seat is stuck in valve body hole the time, can not be used for dismantling valve seat.
Summary of the invention:
The present invention be directed to the problem that prior art exists, adopt the mode in the vertical inserted valve seat groove of pulling block, having designed a kind of is detachable valve plate, the mounting or dismounting tools for valve plate and valve seat of gate valve of dismounting valve seat when also can be used for the valve seat jam takes place.
The present invention is achieved in that and the present invention includes top-pushing mechanism and extrusion and expansion machine structure, it is characterized in that:
Top-pushing mechanism is made of push rod 1, pull bar 3, connecting bolt 4, block 11, nut 10, draw-bar seat 9 and bolt 2, front end at push rod 1 is provided with bullet 12, the front end of bullet 12 and push rod 1 is by being threaded, push rod 1 is arranged in the pull bar 3, front end at pull bar 3 is provided with Connection Block 5, be connected with draw-bar seat 9 by bolt 2 on the flange of valve body end face, nut 10 and block 11 respectively knob on the pull bar 3 and be enclosed within on the pull bar 3;
The extrusion and expansion machine structure is by bloated pellet 7, bloated pellet seat 14, zero type rubber seal 6 and Connection Block 5 constitute, between Connection Block 5 and bloated pellet seat 14, leave clearance groove, the pellet 7 that expands is arranged in the clearance groove between Connection Block 5 and the bloated pellet seat 14, be provided with the pellet plush copper 13 that expands in the middle of on bloated pellet 7 cylindricals, the both sides of the pellet plush copper 13 that expands are provided with arc groove, and zero type rubber seal 6 is arranged in the arc groove on pellet plush copper 13 both sides of expanding;
Described pull bar 3 is hollow;
The thickness of described bloated pellet 7 leaves the hole that connecting bolt 4 is passed through less than the clearance groove between Connection Block 5 and the bloated pellet seat 14 on every bloated pellet 7;
Described bloated pellet 7 is made of two semicircles, perhaps is made of three semicircles, and the pellet 7 middle circle cambered surfaces that expand are the conical surfaces that match with conical head;
Described bloated pellet seat 14 is connected by the connecting bolt 4 that is arranged on the Connection Block 5 with pull bar 3;
Diameter stimulating the menstrual flow after described zero type rubber seal 6 is shunk less than valve body 16;
During use, first assembling tool is implemented the installation or the dismounting of valve plate and valve seat then;
The installation of valve plate and valve seat:
The tool assembly of regaining the pellet 7 that expands is put into the gate valve passage, with spanner rotation push rod 1, the cone of push rod 1 head is pushed expand the conical surface in the pellet 7, and make in the technology groove of core plush copper 13 inserted valve seats that expand the nut 10 on the rotating rod, tool assembly integral body is pulled outwardly, the valve seat integral installation is put in place, when valve seat all move to into after, the size between two valve seats is greater than the thickness of valve plate, at this moment just valve plate can be inserted the space between two valve seats, carry out the installation exercise of valve plate; After valve plate 8 installs, unscrew nut 10 after, under the effect of wavy spring, two valve seats are just on two end faces that are pressed in valve plate tightly; Carry out above-mentioned contrary operation, with the taking-up of tool assembly, the installation exercise of valve plate is finished; Valve plate, the dismounting of valve seat:
The valve plate valve seat installation procedure operation of the tool assembly that assembles being pressed gate valve is in place, turn clockwise nut 10 on the pull bar 3 under the stopping of block 11, forces tool assembly integral body to be pulled outwardly, when the size between two valve seats is pulled to thickness greater than valve plate, just valve plate can be taken out; After taking out valve plate, the nut 10 on the counter-clockwise rotating rod 3 under the stopping of draw-bar seat 9, makes pull bar 3 drive tool assembly and valve seat motion in the middle part of valve body, thereby pulls down the valve seat that is stuck in the valve seat cover body opening;
The invention has the beneficial effects as follows: the bloated pellet plush copper that is arranged on the push rod front end pellet that will expand squeezes in the technology groove of circle in valve seat firmly, the push rod as long as the step circles round, valve seat and dismounting valve seat just can be installed smoothly, under the effect of block that is provided with and draw-bar seat, as long as valve seat and valve plate can be loaded onto and pull down to clockwise or inhour rotation nut just easily, have quick, convenient and durable characteristics, by extending and shortening pull bar, push rod length, be applicable to valve plate mounting or dismounting, the valve seat dismounting of the gate valve of other 65mm latus rectum of various pressure stages.
