Description

Technical Field

[0001] The present invention belongs to the technical field of valve wells, and particularly relates to a water supply valve well suitable for pressure flow drainage. Background Art

[0002] Traditional valve wells, such as brick-built valve wells and reinforced concrete valve wells, are composed of a reinforced concrete cover plate, a well wall, and a well bottom. The well shaft is in the form of brickwork. The well bottom contains a small sump (with a diameter of 0.3 m and a depth of 0.5 m), and there is no dedicated drainage well chamber, so it is not easy to drain the accumulated water. The structural design uses steel bar connections, and welding or mechanical connections are preferred. Although it meets the requirements of the water supply and drainage system to a certain extent, there are still deficiencies in terms of sealing performance, pressure-bearing capacity, and corrosion resistance. Especially under soil settlement, geological disasters, or extreme climate conditions, traditional valve wells are prone to problems such as well body collapse, water seepage, and leakage. The pipeline valves are immersed in water for a long time, seriously affecting the normal operation of the water supply and drainage system and the water supply safety. Therefore, it is particularly important to develop a new type of water supply valve well that can drain water under pressure flow. Summary of the Invention

[0024] The present invention will be described in detail below in conjunction with the specific implementation manners.

[0025] Such as Figure 1 、 2As shown in the figure, the water supply valve well of the present invention applicable to pressure flow drainage includes a pump well 1 and a valve well body 2. One side of the pump well 1 is fixedly installed on one side of the valve well body 2; the bottom of the pump well 1 is lower than the bottom of the valve well body 2; the pump well 1 and the valve well body 2 are connected as a whole;

[0026] A submersible sewage pump 6 is arranged at the bottom of the pump well 1, and a drain pipe 5 is installed at the output end of the submersible sewage pump 6 and penetrates and extends to the outside of the pump well 1;

[0027] A connecting pipe 7 is installed on the right side of the bottom of the valve well body 2 and penetrates and extends into the pump well 1. The water in the valve well body 2 can be drained into the pump well 1 through the connecting pipe 7.

[0028] As Figure 3 shown, installation holes are opened at the tops of both the pump well 1 and the valve well body 2. A well seat 4 is arranged in the installation hole, and a manhole cover 3 is hinged on the well seat 4. A through hole smaller than the diameter of the manhole cover 3 is opened at the lower part of the well seat 4, and a circular sealing groove is opened on the top surface of the through hole; a sealing ring 9 is installed on the bottom surface of the manhole cover 3, and the sealing ring 9 matches the circular sealing groove opened on the top surface of the through hole of the well seat 4. When the manhole cover 3 is closed, the sealing groove can be sealed through the sealing ring 9, realizing the sealing of the manhole cover 3. The sealing ring 9 is made of corrosion-resistant rubber material.

[0029] Placing grooves are opened on the top surface of the outer ring of the installation holes opened at the tops of the pump well 1 and the pump gate well body 2, and annular flexible protrusions 8 are arranged in the placing grooves. The annular flexible protrusions 8 can achieve sealing when being extruded.

[0030] As Figure 4 、 5 shown, the annular flexible protrusion 8 includes a flexible outer shell, and a plurality of diamond-shaped frames arranged in the vertical direction are arranged in the flexible outer shell. The two ends of the diamond-shaped frame in the vertical direction are respectively fixed to the top and bottom of the flexible shell body, and the two ends of the diamond-shaped frame in the horizontal direction respectively abut against the inner wall of the flexible outer shell. The diamond-shaped frame is composed of four hinged rods 10 connected end to end and hinged to each other.

[0031] The well wall of the pump well 1, the well wall of the valve well body 2, the manhole cover 3 and the well seat 4 are all made of high-strength and corrosion-resistant materials. In this embodiment, high-density polyethylene is used. It can save the construction progress, facilitate maintenance management, and is convenient for later operation and maintenance and simple for overhaul.

[0032] The working principle and usage process of the present invention are as follows:

[0033] The accumulated water in the valve well body 2 can flow into the pump well 1 through the connecting pipe 7. At this time, the submersible sewage pump 6 can be started, and the water in the pump well 1 can be discharged into the nearby drainage ditch or rainwater inlet through the drain pipe 5. An annular flexible convex block 8 is placed in the grooves opened on the pump well 1 and the valve well body 2. When the annular flexible convex block 8 is placed in the placement groove opened on the pump well 1 and the valve well body 2, the top of the annular flexible convex block 8 is squeezed by the well seat 4 and deforms under force, thereby increasing the contact area and sealing performance between the annular flexible convex block 8 and the placement groove. At the same time, the manhole cover 3 and the well seat 4 are sealed through the rubber sealing ring 9 structure.

[0034] In the description of the present invention, unless otherwise clearly specified and limited, the terms "set", "installed", "connected", "connected", "fixed" shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0035] The content of the present invention is not limited to the examples listed. Any equivalent transformation of the technical solution of the present invention adopted by those of ordinary skill in the art by reading the specification of the present invention is covered by the claims of the present invention.
