Background technology
When valve seat or fixator assembling, can relate to situation with the effect of spring pretension, because the valve body lumen is a cavernous structure, operating position is restricted, and installs very inconvenient.
Summary of the invention
The utility model purpose provides a kind of valve assembling specific purpose tool, to be suitable for installing valve seat or the fixator with spring pretension.
For achieving the above object, the technical solution adopted in the utility model is: a kind of valve assembling specific purpose tool, comprise hollow trombone slide, be arranged at trombone slide one end executing agency, be positioned at trombone slide transmission tube, be set in space washer and nut on the trombone slide, described trombone slide periphery cooperates with described nut and is provided with external screw thread; Described executing agency is, by cover plate, retainer and holder constitute head, holder is fixedlyed connected with described trombone slide one end, offer three radially slideways on the described retainer, be provided with three tongue pieces, lay respectively in the described radially slideway, have a hole on each tongue piece, each tongue piece rear end is provided with a spring, at the spring reset state, tongue piece front end stretches out the head periphery, be provided with a driving member in the described holder, described driving member rear end contacts cooperation with described transmission tube, and described driving member front end is provided with three pawl-like members, each pawl-like member correspondence is arranged in the hole on the tongue piece, and the contact site in pawl-like member and hole is the inclined-plane.
In the technique scheme, when pushing transmission tube, the motion of transmission tube compressing driving member, three pawl-like members on the driving member insert respectively in the hole of three tongue pieces, since the ramp effect of pawl-like member, tongue piece compression spring, slide along the slideway on the retainer, be pulled in the retainer; At this moment, executing agency is stretched into valve passage, unclamp transmission tube in the inner groove position of valve seat or fixator, three tongue pieces eject under the effect of spring, snap in the inner groove of valve seat or fixator, utilize the space washer location, rotating nut can put valve seat or fixator tension in place.Press down transmission tube once more, withdraw from behind the tongue piece that can get loose.
Further technical scheme, the other end at described trombone slide is fixed with handle set, and handle set one side is provided with a fixed handle, is rotatably connected to a flexible handle on the handle set, the end of described transmission tube correspondence is provided with fluting, and described flexible handle is arranged in the fluting of described transmission tube.Utilize the cooperation of handle, can realize pushing and getting loose of transmission tube more easily.
Further technical scheme, the back side of described tongue piece is provided with spacing circular arc projection, cooperates with described spacing circular arc projection, is provided with counterbore on described cover plate, constitutes the overhanging position limiting structure of tongue piece.Thereby avoid excessively overhanging dropping out of tongue piece.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
1. the utility model provides a kind of specific purpose tool, utilize three tongue pieces to block the inner groove of valve seat or fixator, by the distance of nut fastening adjustment space washer and tongue interblock, the tension of valve seat or fixator can be put in place, thereby be convenient to the installation of valve seat or fixator.
2. the utility model is easy to operate, particularly by the cooperating of fixed handle and flexible handle, can finish pushing and getting loose of transmission tube with one hand, has improved efficiency of assembling greatly.

The specific embodiment
Below in conjunction with figure and embodiment the utility model is further described:
Embodiment one: extremely shown in Figure 4 referring to Fig. 1, a kind of valve assembling specific purpose tool, comprise hollow trombone slide 1, be arranged at trombone slide 1 one ends executing agency, be positioned at trombone slide 1 transmission tube 2, be set in space washer 3 and nut 4 on the trombone slide 1, described trombone slide 1 periphery cooperates with described nut 4 and is provided with external screw thread; Described executing agency is, by cover plate 5, retainer 6 and holder 7 constitute head, holder 7 is fixedlyed connected with described trombone slide 1 one ends, offer three radially slideways on the described retainer 6, be provided with three tongue pieces 8, lay respectively in the described radially slideway, have a hole on each tongue piece 8, each tongue piece 8 rear end is provided with a spring 9, at the spring reset state, tongue piece 8 front ends stretch out the head periphery, be provided with a driving member 10 in the described holder 7, described driving member 10 rear ends contact cooperation with described transmission tube 2, and described driving member 10 front ends are provided with three pawl-like members 11, each pawl-like member 11 correspondence is arranged in the hole on the tongue piece 8, and pawl-like member 11 is the inclined-plane with the contact site in hole; The other end at described trombone slide 1 is fixed with handle set 12, handle set one side is provided with a fixed handle 13, be rotatably connected to a flexible handle 14 on the handle set 12, the end of described transmission tube 2 correspondences is provided with fluting, and described flexible handle 14 is arranged in the fluting of described transmission tube 2.
In the present embodiment, under the state, the tongue piece is in the locking duty of stretching out under spring action usually; For keeping stress equalization, 3 tongue pieces are circumferentially uniform, select for use high strength steel and heat treatment to improve hardness, bear service load; For guaranteeing the normal effect of spring, guide finger can be set and guide pin hole is set on retainer, guide finger is crossed to win with the tongue piece and is connected, with guide pin hole matched in clearance on the retainer.Guarantee that the tongue piece is flexible at the space free that limits, guide finger does not bear transverse load during work; For restriction tongue piece stroke, at the tongue piece back side spacing circular arc platform is set, spacing counterbore on the cover board is set, promptly realize the travel limits of tongue piece; Three pawl-like members snap in tongue piece center square hole, press flexible handle, promote three pawl-like members by transmission tube, promote tongue piece compression spring and are contracted in the retainer by conical surface effect; During nature, three-jaw promotes transmission tube in the other direction under spring action, thereby makes flexible handle be in normally open, shrinks even press the tongue piece.
During use, hand steered firmly a valve seat or a fixator put it into valve body lumen seat ring aperture, a hand is pressed the specific purpose tool flexible handle, and its head is stretched into valve passage, sounds out the inner groove position of valve seat or fixator, unclamp flexible handle after souning out, the tongue piece pins valve seat or fixator.The turn nut can put valve seat or fixator tension in place again, and flashboard or spheroid are installed to the position, unclamps nut, presses flexible handle and can take out assembly tool.So step is promptly finished a work period, improves efficiency of assembling greatly.
