Abstract
The utility model relates to a valve which can change the valve base and solve the disadvantages of the prior art which wastes time, labor and raw material and influence the producing as the prior valve needs to be detected or changed completely once the valve is leaking. The utility model is characterized in that the bottom part of the valve body 1 is provided with an inner hexagon blind hole 5; the screw 7 is positioned in the blind hole 5; the pin plate 6 is sleeved in the inner hexagon blind hole 5 and is rotated by ninety degree; the pressing plate 4 and the screw cap 3 are connected with the screw 7 in order; one end of the changeable valve base 2 is contacted with the edge of the pressing plate 4; the other end of the changeable valve base 2 is connected with the valve body. When the changeable valve base is damaged, the valve base can be exchanged. The utility model can reduce the detecting time and the exchange cost of the valve. The fixed valve base is not easy to be damaged and can be welded with the pipe. The utility model can reduce the leaking of the medium, saves the operating cost of the flange and the helix connection. The utility model can be used by the medium in the controlling pipe.
Description
The utility model relates to a kind of valve, particularly a kind of gate valve with exchangeable valve seat.
Gate valve of the prior art its objective is the medium circulation in the pilot line.Its structure is that a spool is set in the valve seat, and the two ends of valve seat link to each other with pipeline.Its deficiency is in use, and sealing surface is damaged to be leaked because of wearing and tearing, dielectric corrosion, wash away etc. makes.In order to reduce leakage, sealing surface is generally selected mill property, red hardness, corrosion-resistant good alloy material for use, but the material that damages anything but is non-existent.So because of the sealing surface damage causes gate valve to leak is inevitable.In case leak then must overhaul or whole gate valve is more changed, time-consuming, effort, the waste raw material influence production.
The purpose of this utility model is to solve above-mentioned deficiency of the prior art, and a kind of gate valve with exchangeable valve seat is provided.
Technical solution of the present utility model is: be shaped on hexagonal blind hole 5 in the bottom of valve body 1.Bolt 7 is placed in one.Pin plate 6 is placed in to place in the interior hexagonal blind hole 5 on the bolt 7 and revolve and turn 90 degrees.Pressing plate 4 links to each other with bolt 7 successively with nut 3.One end of exchangeable valve seat 2 and the side edge of pressing plate 4 are touched.The other end of exchangeable valve seat 2 is connected with valve body.After using a period of time, if exchangeable valve seat 2 damages, then can unload replacing, and needn't change whole gate valve.
The advantage that the utility model is had compared to existing technology is:
1, shortens the repair time, reduce whole valve renewal cost.
2, fixed valve base is not fragile, can be welded to connect with pipeline.Reduced medium and leaked, the processing cost that saved flange, is threaded.
