AI Technical Summary
It is difficult to remove the valve seat during the maintenance process, resulting in delays in maintenance progress and increased costs. It is mainly because the valve seat is not equipped with a special fixing point for removal, resulting in a small gap and deep depth, making it difficult to effectively disassemble it.
A device including fixing steel plates, adjusting steel plates and screws is designed. The adjusting steel plates are provided with bolt holes and adjustment grooves. The screw rod is fixed by nuts, which can drive the adjusting steel plates and double-headed bolts to pull up and remove the valve seat.
It effectively solves the problem of difficulty in removing the valve seat, improves maintenance efficiency, reduces maintenance costs, and optimizes the maintenance process and reduces equipment damage.

Abstract
Description
Technical Field
[0001] The utility model relates to a simple device for taking out a valve seat of a regulating valve. Background Art
[0002] The valve seat of the regulating valve plays an important sealing role during the maintenance process, so the grinding of the valve seat sealing surface is very important. Because the valve seat is not equipped with a special removal fixing point, the valve diameter is small, the depth is deep, and the gap is small, it is difficult to remove the valve seat, and the maintenance work is difficult to carry out, delaying the maintenance progress and maintenance period. Summary of the invention
[0003] The utility model aims to provide a simple device for removing a valve seat of a regulating valve.
[0004] The above purpose is achieved through the following technical solutions:
[0005] A simple regulating valve seat removal device comprises a fixed steel plate, an adjusting steel plate and a screw rod, a bolt hole is provided in the middle of the adjusting steel plate, a round hole is provided in the middle of the fixing steel plate, a screw rod is screwed into the bolt hole, and the screw rod passes through the round hole on the fixing steel plate, the adjusting steel plate and the fixing steel plate are in parallel structure, two adjusting grooves are symmetrically provided on the adjusting steel plate, and stud bolts are respectively installed in the two adjusting grooves.
[0006] The simple regulating valve seat removal device has a nut fixedly connected to the screw rod.
[0007] The simple regulating valve seat removal device, the regulating steel plate is a steel plate with a length of 20 cm and a width of 5 cm.
[0008] The simple regulating valve seat removal device has a regulating groove with a length of 7 cm. Beneficial Effects
[0009] 1. The utility model can effectively solve the problem of difficult removal of the regulating valve seat, thereby improving maintenance efficiency and saving maintenance costs. It optimizes the maintenance process, can not only complete the maintenance efficiently but also minimize the damage caused to the equipment during the maintenance process.
[0010] 2. The utility model has symmetrical adjusting grooves on the adjusting steel plate, each of which has a stud bolt in it for adjusting the opening according to the size of the valve seat. A bolt hole with threaded threads is processed in the middle of the steel plate for connecting the screw rod. The upper steel plate is a fixed steel plate, and the screw rod is fixed on the adjusting steel plate. The valve seat can be pulled up and raised by tightening the nut on the fixed plate.

[0015] A simple regulating valve seat removal device includes a fixed steel plate 1, an adjusting steel plate 2 and a screw 3. A bolt hole 4 is provided in the middle of the adjusting steel plate, a round hole 5 is provided in the middle of the fixing steel plate, a screw is screwed into the bolt hole, and the screw passes through the round hole on the fixing steel plate. The adjusting steel plate and the fixing steel plate are parallel structures. Two adjusting grooves 6 are symmetrically provided on the adjusting steel plate, and stud bolts 7 are respectively installed in the two adjusting grooves. The stud bolts are composed of a screw and two adjusting nuts. A nut 8 is fixedly connected to the screw, and the nut is fixedly connected to the screw as a whole by welding. Example
[0016] A simple regulating valve seat removal device, wherein the regulating steel plate is a steel plate with a length of 20 cm and a width of 5 cm. The length of the regulating groove is 7 cm. When in use, first insert the regulating steel plate into the valve seat, and then insert the lower nut on the stud bolt and the regulating steel plate into the orifice plate of the valve seat. The length of the fixed steel plate is greater than the diameter of the valve seat, and the fixed steel plate is set at the end of the regulating valve. When the valve seat is to be removed from the regulating valve, the nut on the screw rod is twisted. Since the nut and the screw rod are welded and fixed, the nut drives the screw rod to rotate, and the screw rod cooperates with the threaded hole on the regulating steel plate through the threaded structure, so the screw rod will drive the regulating steel plate to move vertically upward, thereby pulling up the valve seat through the two stud bolts on the adjusting steel plate.
