Problems solved by technology

[0003] In view of the related technologies mentioned above, the inventor believes that if the direction of water pressure is opposite, the rubber strips around the gate cannot be pressed against the gate frame, and the gate will leak, so the water-stopping effect of the water-stop valve cannot be guaranteed.

Embodiment Construction

[0030] The following is combined with the attached Figure 1-3 Further elaboration of this application.

[0031] Embodiment of the present application is a kind of open two-way water stop valve. Reference Figure 1 and Figure 2 , two-way waterstop valve includes gate frame 1, gate frame 1 in the vertical direction sliding connected to the gate 2, gate frame 1 is installed with a screw lift 3, the bottom end of the lead screw lift 3 of the screw lift 3 and gate 2 are connected, so as to achieve the up and down movement of gate 2. Both sides of the gate 2 are fixedly connected with a water-stop rubber strip 4, the water-stop rubber strip 4 is located around the side wall of the gate 2 and closes the gate frame 1 setting, so that the water pressure no matter which side of the gate 2, can make the gate 2 through the water-stop rubber strip 4 to resist the gate frame 1 to play a tight sealing effect, reducing the possibility of leakage of gate 2.

Abstract

This application relates to the field of urban drainage, in particular to a two-way water stop valve, which is characterized in that it includes a gate frame, a gate is slidably connected to the gate frame, a screw lift is provided on the gate frame, and the wire The end of the screw rod of the rod lifter is connected with the gate. Both sides of the gate are connected with water-stop rubber strips. pressure relief structure. The application has the advantage of improving the water-stopping effect of the water-stop valve.

Description

Technical field [0001] The present application relates to the field of urban drainage, in particular to a two-way water stop valve. Background [0002] The gate is used as a water level control device. Commonly used gates can be divided into cast iron gates and steel gates according to the material, due to the high strength of steel gates and light weight. Simple construction 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 strip around the side of the gate under the action of positive water pressure, so as to achieve the sealing effect. [0003] In view of the above related technologies, the inventor believes that if the water pressure is reversed, the rubber strip around the gate cannot be pressed with the gate frame, and the gate will leak, so that the water stop effect of the water stop valve cannot be guaranteed.
