Abstract
The utility model provides an ultrafiltration type trace intake and exhaust valve, the middle part of trace exhaust valve body and the port of stainless steel casing adopt spinning connection structure to cover the intake and exhaust port of trace exhaust valve body, the screw thread interface of trace exhaust valve body exposes in the outside, the upper end of stainless steel casing adopts spinning connection structure installation multilayer stainless steel sintering net or stainless steel powder sintering filter plate, the advantage is, installs at pipeline corner, stationary flow jar and the container top of water supply system of water distribution network and secondary booster pump station, occupation space is little, not only environmental protection, but also health. In addition, when the water supply system is powered off, water is cut off, the pressure of a pipe network is reduced, air can be fed when the pipe network has negative pressure, and the stainless steel powder sintering filter disc can effectively filter and intercept harmful gas of dust particles from entering the water delivery system, so that the pollution to drinking water is avoided.
Description
Technical Field
The utility model relates to a part in the water supply system, in particular to an ultrafiltration type micro air inlet and outlet valve.
Background
Some air inevitably exists in the water supply system of the water transmission and distribution pipe network and the secondary booster pump station, the air forms air mass to accumulate at the highest point or local high point in the system, such as the corner of a pipeline, the top of a steady flow tank and a container, the air runs along with water in the pipe network system in the form of free bubbles to form an air bag or an air plug, and the running efficiency of the water transmission and distribution pipe network system is influenced. In order to solve the problems, at present, most of the exhaust valves made of cast iron are adopted in water supply systems of water distribution and delivery pipe networks and secondary booster pump stations, and the exhaust valves are large in size, rough in surface, large in occupied space, poor in corrosion resistance and corrosion resistance, not environment-friendly and unsanitary.
Disclosure of Invention
An object of the utility model is to solve the above-mentioned current problem that exists, provide an ultrafiltration type trace intake and exhaust valve that occupation space is little, both environmental protection, and is sanitary again.
The utility model discloses a realize like this: there are two connection structure ways:
the first connecting structure is as follows: the middle part of the micro exhaust valve body and the port of the stainless steel shell adopt a spinning connection structure to cover the air inlet and outlet of the micro exhaust valve body, the threaded connection port of the micro exhaust valve body is exposed outside, the upper end of the stainless steel shell adopts a spinning connection structure to install a plurality of layers of stainless steel sintering nets or stainless steel powder sintering filter sheets, and harmful gas of dust particles is filtered and intercepted to enter a water delivery system.
The second connection structure is: the welding of the lower part neck department of trace exhaust valve body has the connector, through the internal thread connection of the external screw thread of connector and stainless steel casing link to install the sealing washer, in order to cover the air inlet and outlet of trace exhaust valve body, the lower part screw thread interface of trace exhaust valve body exposes in the outside, and the upper end of stainless steel casing adopts spinning connection structure installation multilayer stainless steel sintering net or stainless steel powder sintering cassette, can dismantle, overhauls, simple to operate.
The utility model has the advantages that, install pipeline corner, stationary flow jar and the container top at water distribution pipe net and secondary booster pump station water supply system, occupation space is little, not only environmental protection, but also health. The free body in the effectual discharge and release system, in addition, have a power failure, the water cut off, pipe network pressure drops in water supply system, can admit air when the negative pressure appears in the pipe network, especially, the upper end of stainless steel casing 1 adopts spinning connection structure installation multilayer stainless steel sintering net or stainless steel powder sintering filter 5. Can effectively filter and intercept harmful gas of dust particles from entering a water delivery system, thereby avoiding the pollution to drinking water.
Drawings
Fig. 1 is a schematic view of a first connection structure of the present invention;
fig. 2 is a schematic view of a second connection structure of the present invention.
Detailed Description
The following detailed description is made with reference to the accompanying drawings: as shown, the first connection structure is: the middle part of the micro exhaust valve body 3 and the port of the stainless steel shell 1 adopt a spinning connection structure to cover the air inlet and outlet 2 of the micro exhaust valve body 3, the threaded connection port 4 of the micro exhaust valve body 3 is exposed outside, the upper end of the stainless steel shell 1 adopts a spinning connection structure to install a plurality of layers of stainless steel sintering nets or stainless steel powder sintering filter sheets 5, and dust particle harmful gas is filtered and intercepted to enter a water delivery system.
The second connection structure is: the lower connector 7 is welded at the lower neck of the micro exhaust valve body 3 and is connected with the inner thread of the connecting end of the stainless steel shell 1 through the outer thread of the lower connector 7, the sealing ring 6 is installed to cover the air inlet and outlet 2 of the micro exhaust valve body 3, the thread connecting port 4 of the micro exhaust valve body 3 is exposed outside, and the multi-layer stainless steel sintering net or the stainless steel powder sintering filter 5 is installed at the upper end of the stainless steel shell 1 through a spinning connection structure. Can be disassembled, and is convenient to overhaul and install.
