Description

Technical Field

[0001] The utility model relates to the technical field of gate valves, in particular to an energy storage emergency electric gate valve. Background Art

[0002] Simply put, an electric valve uses an electric actuator to control the valve, thereby realizing the opening and closing of the valve. It can be divided into two parts, the upper part is the electric actuator, and the lower part is the valve.

[0003] Emergency electric gate valves are mainly used to replace the gate valves of the outlet manifold of the water injection station and the gate valves of the water supply main line of the water distribution room, so as to quickly shut down the leaking pipeline after the leakage alarm is triggered to prevent disasters.

[0004] However, when the electric gate valve is in use, it is easy for sediment to settle inside the valve body, which affects the long-term use of the gate valve.

[0005] Therefore, we proposed an energy storage emergency electric gate valve to solve the above problems. Utility Model Content

[0006] 1. Technical issues to be resolved

[0007] In view of the deficiencies in the prior art, the utility model provides an energy storage emergency electric gate valve, which solves the problem that sediment is easily deposited inside the valve body.

[0008] (II) Technical solution

[0009] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0010] A storage emergency electric gate valve comprises a valve body and an electric actuator, wherein an elastic valve seat is arranged inside the valve body, a valve cover is arranged on the top of the valve body, the electric actuator is mounted on the valve cover, a valve stem shaft is mounted on the output end of the electric actuator, a Gley sealing ring is arranged between the valve stem shaft and the valve cover, a metal sealing ring is mounted between the valve cover and the valve body, and a parallel gate plate is fixedly connected to the bottom end of the valve stem shaft.

[0011] Furthermore, elastic metal sheets are provided at positions on both sides of the elastic valve seat that contact the valve body.

[0012] Furthermore, a planar thrust bearing is provided between the valve stem shaft and the valve cover.

[0013] Furthermore, a grease nipple is provided on one side of the valve body.

[0014] Furthermore, the parallel gate plate contacts with the elastic valve seat and slides relatively thereto.

[0015] (III) Beneficial effects

[0016] Compared with the prior art, the utility model provides an energy storage emergency electric gate valve, which has the following

[0017] Beneficial effects:

[0018] The utility model has the parallel gate plates in close contact with the elastic valve seat, and can remove the scale layer attached to the valve body when moving up and down. When the valve is fully open, the medium flows through the flow channel and the scale cannot be deposited on the valve body. The seal is improved from graphite filler to metal ring and Gly ring, and the seal wear cycle is prolonged and the sealing effect is better, which solves the problem of the valve stem and the grinding wheel being separated due to corrosion.

[0020] In the figure: 1. elastic valve seat; 2. valve body; 3. parallel gate; 4. elastic valve seat; 5. valve stem shaft; 6. Gley sealing ring; 7. plane thrust bearing; 8. grease nipple; 9. metal sealing ring; 10. electric actuator. DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example

[0023] like Figure 1 As shown, an energy storage emergency electric gate valve proposed in an embodiment of the utility model includes a valve body 2 and an electric actuator 10, wherein an elastic valve seat (1, 4) is arranged inside the valve body 2, a valve cover is arranged on the top of the valve body 2, the electric actuator 10 is installed on the valve cover, a valve stem shaft 5 is installed at the output end of the electric actuator 10, a Gley sealing ring 6 is arranged between the valve stem shaft 5 and the valve cover, a metal sealing ring 9 is installed between the valve cover and the valve body 2, a parallel gate plate 3 is fixedly connected to the bottom end of the valve stem shaft 5, the parallel gate plate 3 is in close contact with the elastic valve seat (1, 4), and can remove the scale layer attached to the valve body when moving up and down, and when the valve is fully opened, when the medium flows through the flow channel, the heavy objects cannot be deposited on the valve body.

[0024] like Figure 1As shown, in some embodiments, elastic metal sheets are provided at the positions where the two sides of the elastic valve seat (1, 4) contact the valve body 2. The elastic metal sheets can be common arc-shaped elastic metal sheets. The purpose is to allow a certain extrusion force between the valve seat and the gate plate to achieve better sealing. In addition, the volume of the elastic metal sheet should not be too large. If it is too large, it will affect the sealing between the valve seat and the valve body. It is sufficient to provide a little elasticity.

[0025] like Figure 1 As shown, in some embodiments, a planar thrust bearing 7 is provided between the valve stem shaft 5 and the valve cover.

[0026] like Figure 1 As shown, in some embodiments, a grease nipple 8 is provided on one side of the valve body 2. The function of the grease nipple 8 is to inject grease after opening to achieve a lubricating effect.

[0027] like Figure 1 As shown, in some embodiments, the parallel gate plate 3 and the elastic valve seat (1, 4) are in conflict and slide relative to each other, which means that the parallel gate plate 3 and the elastic valve seat (1, 4) fit together under the drive of elasticity and have good sealing performance.

[0028] The above-mentioned seal is improved from graphite filler to metal ring and Gly ring, the seal wear cycle is longer, and the sealing effect is better, which solves the problem of valve stem and grinding wheel separation due to corrosion.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
