Problems solved by technology

At present, the valves used in this part often use manual gate valves or butterfly valves. The working principle is to move the valve plate by rotating the screw with the hand wheel. It often takes several turns to move the valve plate a little, so the closing time of the valve is longer.

Embodiment Construction

[0017] The fire-fighting fast valve includes a left valve body 1, a right valve body 14, a valve seat 4 arranged in the valve body, a valve plate 2 matched with the valve seat and a handle 10 connected with the valve plate. In this embodiment, the valve seats 4 are two flat plates made of stainless steel, which are arranged radially symmetrically in the inner cavities of the left and right valve bodies respectively, and the two valve seats 4 are respectively fixed on the left and right sides by pins 5. on the valve body. The valve plate 2 is a flat plate made of stainless steel sandwiched between two valve seats, and the surfaces on both sides of the valve plate 2 are slidingly matched with the surfaces of the two valve seats 4 respectively. At least one through hole 3 corresponding to each other is respectively arranged on the valve seat 4 and the valve plate 2. In this embodiment, there are twenty through holes, and all the through holes are arranged regularly. Finally, the...

Abstract

The fast valve specially for fire fighting includes one right valve body, one left valve body, one valve seat inside the valve bodies, one valve plate matching the valve seat and one handle connected to the valve plate. The valve seat and the valve plate are set radically inside the valve bodies and fitted mutually via plates, and have through holes corresponding to each other. Normally, water flows through the through holes, and shifting the valve plate to stagger the through hole in the valve seat and that in the valve plate can cut off water flow. The shift stroke of the valve plate is equal to the diameter of hole or only 20-25 % shift stroke of common gate valve, so that the valve has fast operation. In addition, the valve may be operated conveniently through one long tool.

Description

technical field [0001] The invention relates to a valve, in particular to a fast valve specially used for fire protection. Background technique [0002] The valve installed in front of the fire hydrant is generally in a normally open state to ensure that the fire hydrant has water at any time. However, when there is a problem with the fire hydrant, it is required that the valve can be closed quickly to cut off the water flow, so as to minimize the maintenance time. At present, manual gate valves or butterfly valves are often used in this area. The working principle is to move the valve plate by rotating the screw with the hand wheel. It often takes several turns to move the valve plate a little, so the closing time of the valve is longer. In addition, because the valve is generally installed in a valve well with a depth of 2 to 3 meters, the valve is often submerged in water. When the valve is closed, the operator needs to wear waterproof clothing and go down to the valve w...
