Abstract

A fire-fighting integral valve shaft relates to a valve shaft for fire fighting, which mainly aims at resolving that an existing valve shaft wastes time and labor in construction, is not convenient to maintain and high in maintenance cost and the like. The fire-fighting integral valve shaft comprises a shaft body, a manhole is arranged at the top of the shaft body, a water collecting pit is arranged at the bottom of the shaft body and communicated with the inside of the shaft body. A water inlet pipe extends from outside the shaft body into the shaft body, a gate valve and a water escape valve are arranged on the water inlet pipe in the shaft body, a valve rod of the gate valve extends out of the top of the shaft body, a flange is arranged at an end portion of the water inlet pipe above the water escape valve, and an opening is arranged at the top of the shaft body. The fire-fighting integral valve shaft has the advantages of being convenient to install and maintain and low in maintenance cost.

Description

The integrated valve well of fire-fighting

Technical field:

The utility model relates to the valve well that a kind of fire-fighting is used.

Background technology:

Existing fire-fighting is that first facing down on ground digged pit with the building course of valve well, with brick or build with steel concrete and to form, in valve well, adorns fire protection pipeline then; On fire protection pipeline, adorn stop valve, also will outside valve well, dig a hole again, fire protection pipeline extend out to from valve well in the hole of newly digging; In this hole with hydrant or water cannon welded and installed on fire protection pipeline, shortcoming is that the construction valve well is wasted time and energy inconvenient maintenance; Maintenance cost is high; Because the borehole wall is brick or builds with steel concrete and to form, is prone in valve well, seep water corrosion pipeline.

Summary of the invention:

It is easy that the utility model technical problem to be solved provides a kind of construction, the integrated valve well of installation and maintenance fire-fighting easily.

Above-mentioned purpose is achieved in that it comprises the well body of processing with metal material, and manhole is arranged at well body top, and sump is arranged at well body bottom; The well body is inner to be communicated with sump, and water inlet pipe extend in the well body from well is external, on the water inlet pipe in the well body gate valve and drain valve is arranged; The valve rod of gate valve stretches out from the top of well body; There is flange the water inlet pipe end of drain valve top, and confession is connected fixing with hydrant or water cannon, and well body top also has opening; When hydrant or water cannon were installed, hydrant or water cannon reach well from this opening external.

The utility model has the advantages that hydrant or water cannon are connected fixing with water inlet pipe because the water inlet pipe end in the well body has confession to be connected fixing flange with hydrant or water cannon in the well body, thus do not need to dig the hole that hydrant or water cannon are installed in addition, easy for installation; When the pipeline in the well body and valve break down, service worker from manhole down to and in keeps in repair, so easy to maintenance; Maintenance cost is low, again owing to be provided with sump in well body bottom, when hydrant or water cannon need draining; Water can flow in the sump, is convenient to discharge; In addition, this device only needs to dig a hole on ground when mounted and gets final product, and it is convenient to install.

Description of drawings:

Fig. 1 is the structural representation of the utility model;

Fig. 2 is contained in the structural representation on the utility model with water cannon, and 10 is water cannons among the figure;

Fig. 3 is contained in the structural representation on the utility model with hydrant, and 11 is hydrants among the figure.

The specific embodiment:

With reference to Fig. 1, it comprises the well body of processing with metal material 1, and manhole 2 is arranged at well body top; Sump 8 is arranged at well body bottom, and the well body is inner to be communicated with sump, and water inlet pipe 9 extend in the well body from well is external; Gate valve 7 and drain valve 6 are arranged on the water inlet pipe in the well body; The valve rod 3 of gate valve 7 stretches out from the top of well body, and there is flange 5 the water inlet pipe end of drain valve top, and well body top also has opening 4.
