Description

Technical Field

[0001] The utility model relates to the technical field of stop valves, in particular to a stop valve which is convenient for adjusting flow. Background Art

[0002] The opening and closing part of the stop valve is a plug-shaped valve disc, and the sealing surface is a plane or a sea cone surface. The valve disc moves linearly along the center line of the valve seat. The movement form of the valve stem is also a lifting and rotating rod type, which can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media; Patent No. CN202122517228.6 discloses a stop valve that is easy to adjust the flow. Through the cooperation between the valve body and the adjustment device, the output shaft of the servo motor drives the first gear to rotate, and the meshing force between the first gear and the second gear drives the second gear to rotate forward and backward. The threaded rod rotates forward and backward, so that the connecting rod on the threaded sleeve moves up and down in the grooves on both sides, and the threaded sleeve moves up and down in the valve body, which can automatically adjust the inlet and outlet flow, and is easy to operate; However, when adjusting the flow of the stop valve, it is inconvenient to control the lifting and lowering of the valve plate inside the valve body, which makes the staff unclear about the size of the internal flow of the stop valve after adjustment. To this end, we propose a stop valve that is easy to adjust the flow. Utility Model Content

[0003] In view of the problems in the prior art, the utility model provides a stop valve which is convenient for adjusting flow.

[0004] The technical solution adopted by the utility model to solve the technical problem is a stop valve that is convenient for adjusting flow, comprising a valve body, a disc seat for support is assembled on the top surface of the valve body through bolts, and a vertical plate for support is integrally constructed on the top surface of the disc seat, and there are multiple groups of vertical plates, a slide cylinder for adjustment is slidably mounted on the inner side of the disc seat, and a slide rod slidably connected to the vertical plate is assembled on the outer peripheral surface of the slide cylinder, and a ruler body corresponding to the slide rod is assembled on the outer side wall surface of the vertical plate;

[0005] The inner side of the valve body is integrally constructed with a ring seat for adjustment, and the inner side of the ring seat is fittedly connected with a conical plug for adjusting the flow rate, and the top surface of the conical plug is equipped with a valve stem integrally constructed with the slide cylinder.

[0006] By adopting the above technical solution, when adjusting the flow inside the stop valve, the slide cylinder inside the disc seat can be moved, so that the slide cylinder can be lifted and lowered and drive the slide rod to move, so that the slide rod can slide and move inside the vertical plate. At the same time, the ruler body outside the vertical plate is conveniently corresponding to the slide rod, so that the staff can clearly understand the distance moved by the slide rod and the slide cylinder, which is convenient for the staff to control the size of the flow when adjusting the flow inside the valve body;

[0007] When the flow inside the stop valve is adjusted, the extended ring seat and the tapered plug cooperate with each other so that the tapered plug can slowly move out of the cone inside the ring seat, thereby adjusting the flow of the stop valve. The displacement of the slide cylinder can drive the tapered plug to move up and down through the valve stem, thereby facilitating the adjustment of the flow of the stop valve.

[0008] Specifically, the end of the vertical plate away from the ring seat is integrally constructed with a supporting ring for connection, and a screw rod threadedly connected to the slide cylinder is rotatably installed on the inner side of the supporting ring. A motor is assembled on the top surface of the supporting ring through bolts, and gears for transmission are mounted on the power output end of the motor and the top surface of the screw rod, and the two sets of gears are meshed and connected to each other.

[0009] By adopting the above technical solution, when the flow inside the stop valve needs to be adjusted, the motor on the top of the support ring can be operated and drive the gear to rotate, so that the gear can mesh and transmit with the gear on the top of the screw rod, so that the screw rod rotatably installed on the inside of the support ring can rotate and mesh with the slide cylinder, and the position of the screw rod will not change, so that the slide cylinder can rise and fall under the force of the screw action, thereby facilitating the regulation of the flow inside the stop valve.

[0010] Specifically, a shell cover for protection is assembled on the top surface of the support ring through bolts.

[0011] By adopting the above technical solution, the shell cover is easy to disassemble and assemble, and it is convenient to protect the structure on the top of the support ring.

[0012] Specifically, a side of the slide rod away from the slide cylinder is coated with an arrow corresponding to the ruler body.

[0013] By adopting the above technical solution, the arrow enables the staff to more clearly understand the lifting and moving distance of the sliding rod.

[0014] Specifically, the outer peripheral inclined surface of the ring seat is provided with inclined holes for guiding flow, and there are multiple groups of inclined holes.

[0015] By adopting the above technical solution, the inclined hole enables the water source to more conveniently enter the gap between the tapered plug and the tapered hole inside the ring seat.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. The technical solution of the present application, through the design of the disc seat, vertical plate, sliding rod, sliding cylinder and ruler body, can move the sliding cylinder inside the disc seat when adjusting the flow inside the stop valve, so that the sliding cylinder can be raised and lowered and drive the sliding rod to move, so that the sliding rod can slide and displace inside the vertical plate. At the same time, the ruler body outside the vertical plate is convenient to correspond to the sliding rod, so that the staff can clearly understand the distance moved by the sliding rod and the sliding cylinder, which is convenient for the staff to control the size of the flow when adjusting the flow inside the valve body.

[0018] 2. The technical solution of the present application adopts the design of the tapered plug, the ring seat and the valve stem. When the flow inside the stop valve is adjusted, the extended ring seat and the tapered plug cooperate with each other, so that the tapered plug can be slowly moved out from the cone inside the ring seat, thereby regulating the flow of the stop valve. The displacement of the slide cylinder can drive the tapered plug to move up and down through the valve stem, thereby facilitating the regulation of the flow of the stop valve.
