Description

a gate

technical field

The utility model belongs to a water treatment device, and mainly relates to a water level control and a steel maintenance gate for blocking upstream incoming water and providing a maintenance environment when water treatment equipment is maintained.

Background technique

The gate acts as a water level control device. Commonly used gates can be divided into cast iron gates and steel gates according to their materials. Due to the high strength and light weight of steel gates. The structure is simple and does not require molds, and the size is flexible. Therefore, steel gates are the most commonly used gates in the water treatment industry. The steel gate is pressed against the gate frame by the rubber strips around the gate body under the action of positive water pressure, so as to achieve the sealing effect. If the water pressure direction is reversed, the rubber strip cannot be pressed tightly with the door frame, and the gate will leak, which cannot achieve the water-stop effect. If rubber strips are installed on both sides of the gate, the friction between the rubber strip and the gate frame will be too large when the gate is opened and closed under the action of water pressure, and the equipment will be easily damaged and difficult to use normally. In addition, after the maintenance of the downstream equipment is completed, when the traditional maintenance gate is opened, the upstream water flows down instantly, which may impact the downstream water treatment equipment, cause certain damage to the equipment, and pose a safety hazard to the operators.

Contents of the invention

The purpose of this utility model is to overcome the deficiencies of traditional steel gates, and provide a steel maintenance gate that can be applied to water pressure in different directions, and the discharge flow can be adjusted to reduce the instantaneous water flow to downstream equipment when the gate is opened, and the opening and closing is safe and reliable.

In order to solve the above technical problems, the technical solution adopted by the utility model is: a gate, including a gate body and a gate frame, the gate body is installed in the gate frame, and the gate body is connected with a A closed opening and closing device; an overflow pipe connecting both sides of the gate is provided in the gate body; a valve for opening and closing the overflow pipe is provided on one side opening of the overflow pipe.

The opening and closing device includes a hoist, a movable hanger and a hanger; the hanger is fixedly connected to the top of the gate body; the movable hanger is slidably installed in the hanger; The hoist is connected through a transmission screw; the valve is connected with the bottom of the movable hanger.

An elliptical groove is opened on the movable hanger, and a lifting pin that can slide in the elliptical groove is arranged in the elliptical groove; the lifting pin is fixedly connected with the hanging seat.

The movable hanger is connected to the valve through a ball hanger; one end of the ball hanger is spherical, and a spherical groove matching the ball hanger is provided on the valve.

The gate body is provided with a water-stop pad on the outlet side of the overflow pipe.

Beneficial effects: compared with the prior art, the utility model has the following advantages:

1. Both sides of the steel maintenance gate of the utility model are equipped with water-stop rubber strips to realize two-way pressure, and a new type of discharge device is adopted to solve the problem of excessive friction when the gate is opened and closed, and the gate is opened and closed safely and reliably.

2. It can adjust the discharge flow, and effectively reduce the impact of water flow on downstream equipment after the maintenance of downstream equipment is completed.

3. With automatic centering function, reducing the impact of stress, the equipment has a long service life and low failure rate.

detailed description

Below in conjunction with accompanying drawing, technical scheme of the present utility model is described in detail:

Fig. 1 is the side structure schematic diagram of the utility model. As shown in Figure 1, the steel maintenance gate of the present utility model includes a hoist 1, a transmission screw 2, a movable hanger 3, a hanger 4, a ball end boom 6, a valve 11, a water stop pad 7, and an overflow pipe 8. The gate body 9 and the gate frame 10. The gate body 9 is installed in the gate frame 10, and both sides are equipped with sealing strips to cooperate with the gate frame 10. In the utility model, the sealing strips adopt water-stop rubber strips 13. The overflow pipe 8 is installed in the gate body 9 and is connected to both sides of the gate body 9, that is, the overflow pipe 8 is connected to the upstream equipment and the downstream equipment; One side of 8 outlets is equipped with water-stop pad 7. Hanger 4 is fixedly installed on the gate body 9 tops, is provided with slide rail in hanger 4, and movable hanger 3 slides on the slide rail in hanger 4 by slide block 5. The ball-end boom 6 is connected to the bottom of the movable hanger 3, and a spherical groove is provided on the valve 11, which is matched with the spherical boom 6; the valve 11 is set at the mouth of the overflow pipe 8 on the top of the gate body 9, and the water-stop pad 7 are used for opening and closing 8 outlets of the overflow pipe. The upper end of the movable hanger 3 is connected with the hoist 1 through the transmission screw 2, and an oval groove is provided in the movable hanger 3, and a lifting pin 12 which can slide in the oval groove is arranged in the oval groove, and the lifting pin 12 It is fixedly connected with the hanger 4.

When the gate is opened, as shown in Figure 1, Figure 2, Figure 3 and Figure 4, when the hoist 1 is started, first set the transmission screw 2 to move upward for 10-50mm, and the transmission screw 2 drives the movable hanger 3 and the valve 11 moves upward by 10-50mm, the cone valve breaks away from the water-stop pad 7, and the overflow pipe 8 communicates with the water levels on both sides of the gate. At this time, the position of the lifting pin 12 is located in the middle of the oval groove on the movable hanger 3, so the gate body 9 is not closed. taken off the ground. Therefore, the water head on the side with the high water level of the gate flows to the other side through the overflow pipe, which can make the water pressure on both sides of the gate relatively balanced, reduce the pressure of the water head on the gate, and solve the problem that the friction force of the water-stop rubber strips installed on both sides of the gate is too large to open and close safely. After the water pressure balance on both sides of the gate is within a certain range, the hoist 1 continues to operate, the position of the lifting pin 12 is located at the lower edge of the oval groove on the movable hanger 3, and the movable hanger 3 continues to slide upwards, driving the lifting pin 12 to move upward. As a result, the gate body 9 is driven upward, and the lower edge of the gate body 9 leaves the ground until the gate is fully opened. Because the water pressure on both sides of the gate is balanced, the instantaneous impact of the water flow on the downstream equipment is effectively reduced.

When the gate is closed, under the weight of the gate body 9 and the thrust of the drive screw 2, the gate body 9 moves downward until the ball-end boom 6 is coupled with the valve 11. As shown in Figure 5, since the ball-end boom 6 is in spherical contact with the valve 11, it has an automatic centering function, which solves the problem of deformation and jamming of the transmission screw 2 caused by accumulated errors and environmental influences, and ensures that the gate body is completely closed.
