Description
Technical Field
The utility model relates to a grinder, concretely relates to grinder that can be used to valve disk seat.
Background
The gate valve is one of the important components of the Christmas tree and the throttling kill manifold, the quality of one gate valve directly influences the overall quality of the Christmas tree, and the grinding tool device is an important process for embodying the accuracy of the gate valve. In the prior working process, the repairing and machining process of the gate valve is incomplete, the repairing work intensity of workers is high, and the repairing rate of the gate valve is low, wherein the main reason is that the machining precision of a valve seat of the gate valve is insufficient.
At present, many manufacturers are single-base grinding devices, and the bidirectional accurate same machining precision cannot be well realized, so that errors are generated in the bidirectional base grinding process, and the precision cannot be very high. Some manufacturers use abrasives in combination; some abrasives may be incompatible, resulting in seizure. If the grinding precision is reduced due to single heating, the grinding agent is continuously added, and the processing efficiency is influenced by time waste.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a grinder that can be used to valve disk seat, this grinder can realize two-way grinding function.
In order to achieve the above object, the present invention provides a grinding device for valve seats, the device comprising: an upper abrasive disk and a lower abrasive disk; the first connecting rod comprises an upper connecting rod and a lower connecting rod which are movably connected so as to adjust the length of the first connecting rod; the bottom end of the lower connecting rod is connected with the upper grinding disc; the upper part of the second connecting rod is sleeved in the lower connecting rod and can move relative to the lower connecting rod, and the bottom end of the second connecting rod is connected with the lower grinding disc; when the lower connecting rod rotates, the second connecting rod is driven to rotate; the compression component is arranged between the upper grinding disc and the lower grinding disc and surrounds the second connecting rod; in the using state, the grinding device is inserted in the valve seat hole of the valve, and the upper grinding disc and the lower grinding disc are placed on the valve seat to be ground.
Preferably, the upper connecting rod and the lower connecting rod are connected through a bolt.
Preferably, the bolt is a cylindrical pin.
Preferably, the upper grinding disc is in threaded connection with the lower connecting rod; the lower grinding disc is in threaded connection with the second connecting rod.
Preferably, the compression member is a spring.
Preferably, the lower part of the second connecting rod is provided with a conversion joint, and the lower grinding disc is connected with the second connecting rod through the conversion joint.
Has the advantages that:
(1) the grinding device can grind the upper side and the lower side in a two-way manner, so that the grinding efficiency is improved;
(2) the grinding device is provided with a compression part, and the grinding process can be stretched and freely ground;
(3) the grinding device adopts a bidirectional grinding disc, can grind symmetrically, and avoids the influence on the practical service life of the gate valve caused by non-uniform precision in the unilateral grinding process.
Drawings
Fig. 1 is a schematic structural diagram of the grinding device for a valve seat according to the present invention.
Detailed Description
The technical solution of the present invention will be further explained with reference to the accompanying drawings and examples.
As shown in fig. 1, the grinding device for valve seat of the present invention is inserted into the valve seat hole, which comprises: an upper abrasive disc 31 and a lower abrasive disc 32. An upper grinding disk 31 and a lower grinding disk 32 are placed on the valve seat to be ground.
The polishing apparatus further comprises: a first connecting rod consisting of an upper connecting rod 11 and a lower connecting rod 12. The upper connecting rod 11 and the lower connecting rod 12 are connected through the bolt 2, so that the length of the first connecting rod can be adjusted; the plug 2 may use a cylindrical pin. The bottom end of the lower connecting rod 12 is connected with the upper grinding disc 31.
The polishing apparatus further comprises: and the upper part of the second connecting rod 6 is sleeved in the lower connecting rod 12 and can move relative to the lower connecting rod 12, and the bottom end of the second connecting rod 6 is connected with the lower grinding disc 32. When the lower connecting rod 12 rotates, the second connecting rod 6 is driven to rotate. The upper part of the lower connecting rod 12 is also provided with a hollow groove for limiting the moving distance of the second connecting rod 6; the upper part of the second connecting rod 6 is bigger and is limited in the hollow groove, so that the second connecting rod 6 is driven by the lower connecting rod 12 to rotate and limit the moving distance of the second connecting rod 6.
The polishing apparatus further comprises: and a compression member 5 disposed between the upper grinding disk 31 and the lower grinding disk 32 and surrounding the second connecting rod 6.
Compression part select for use the spring, it can effectually slow down pressure, can control reasonable pressure, avoids pressing to grind the in-process too big, generate heat of pressure, causes the condition that grinding precision reduces.
In some embodiments, the upper grinding disk 31 and the first connecting rod, and the lower grinding disk 32 and the second connecting rod 6 are threaded.
In some embodiments, the lower part of the second connecting rod 6 is provided with the conversion joint 4, and the conversion joint 4 has a spherical segment structure matched with the second connecting rod 6; the lower abrasive disc 32 is connected to the adapter 4.
The utility model discloses a can be used to grinder of valve disk seat, the accessible drilling machine drives the head rod rotatory, and the head rod drives abrasive disc 31 and second connecting rod 6 rotation to it is rotatory to drive abrasive disc 32 down through second connecting rod 6.
In conclusion, the grinding device for the valve seat of the utility model can realize the function of bidirectional grinding, is convenient and practical and has high precision; the grinding device can flexibly rotate and freely stretch in the working process, and the grinding requirement and the working efficiency can be well improved.
While the present invention has been described in detail with reference to the preferred embodiments thereof, it should be understood that the above description should not be taken as limiting the present invention. Numerous modifications and alterations to the present invention will become apparent to those skilled in the art upon reading the foregoing description. Accordingly, the scope of the invention should be limited only by the attached claims.
