Abstract
一种用于管道流体开关的组合型微阻止回阀,它是由微阻止回阀、安全阀、小止回阀、小旁路管所构成。该组合型微阻止回阀能使在供水管道停泵后倒流水压超过规定数值时泄流减压,保护管道,并具有结构较简单、体积小、阻力小、耗能少等优点。主要用于冶金、石油、化工、铁路、建筑系统及自来水等部门供水使用。
The utility model relates to a combined micro check valve for pipeline fluid switch, which is composed of a micro check valve, a safety valve, a small check valve and a small bypass pipe. The combined micro-prevention return valve can discharge and reduce pressure when the backflow water pressure exceeds a specified value after the pump is stopped in the water supply pipeline, so as to protect the pipeline, and has the advantages of simple structure, small volume, small resistance, and low energy consumption. It is mainly used for water supply in metallurgy, petroleum, chemical industry, railway, building system and tap water and other departments.
Description
The utility model relates to a kind of combined little resistance safety check that is used for the pipeline fluid switch.
The safety check kind that is used for the pipeline fluid switch at present is a lot.Common have H44 type Tiny Drag Slow Shut Check Valves, H44 type Swing check valve, H45 type Multidisc swing foot valve, a H41 type Lift check valve.Existing Tiny Drag Slow Shut Check Valves, though resistance is little, the power consumption few, its structure is complicated, volume is big, the cost height, the deficiency that rotary-open type and Lift check valve exist is that volume is big, resistance big, power consumption is high.
The purpose of this utility model provides that a kind of structure is simple, volume is little, resistance is little, power consumption less, cost is lower, pipeline had combined little resistance safety check of protective action.
The utility model realizes that the technical solution of above-mentioned purpose is, safety valve is installed on little resistance safety check, the intake pipe of safety valve is installed on the water outlet pipeline section of little resistance safety check, the outlet pipe of safety valve is installed on the water inlet segment of little resistance safety check, on safety valve water outlet and little by-pass pipe that little resistance safety check water inlet segment is connected, little safety check is housed, the installation direction of its little safety check is the water outlet of water intake attachment security valve, make water can only enter little safety check and flow back in the water inlet segment of little resistance safety check, and the water of little resistance safety check water inlet segment can not enter safety valve from the water outlet of safety valve.
The utility model compared with prior art; owing to take abovementioned technology; can make earial drainage decompression when refluence hydraulic pressure surpasses regulation numerical value after the water supply line termination of pumping; fraction refluence water flows back to little resistance safety check water inlet segment through safety valve; safety pressure in the controlling plumbing fixtures exactly; the protection pipeline, and have advantages such as structure is simple, volume is little, resistance is little, power consumption is few.
Below in conjunction with a specific embodiment in accompanying drawing detailed description the utility model.Combined little resistance safety check that present embodiment is made up of little resistance elastomeric check valve, safety valve, little safety check and little by-pass pipe.
Accompanying drawing is the structural representation of combined little resistance safety check.
This combined little resistance safety check comprises that an intake pipe 8 safety valve 7 is installed on the water outlet pipeline section 9 of little resistance elastomeric check valve 3, the outlet pipe 2 of safety valve 7 is installed on the water inlet segment 1 of little resistance elastomeric check valve 3, on safety valve 7 water outlets and little by-pass pipe 6 that little resistance elastomeric check valve 3 water inlet segments 1 are connected a little safety check 5 is installed, the installation direction of little safety check 5 is that the water outlet of its water intake attachment security valve 7 constitutes.Little resistance elastomeric check valve 3 is through identical flanged (FLGD) gradually expanding shape water inlet segment 1, convergent shape water outlet pipeline section 9, flaring change convergent place is provided with a valve body that gusset constituted 4 by its diameter in pipe by two-port, on gusset, be provided with screw, linking two smaller part garden shape valve plates that iron plate is formed 14 to one by garden shape offset plate with press strip 10 and screw 11 is fixed on the gusset of valve body 4, on the shape iron plate of smaller part garden, be provided with position limiting pile 13, in the upper end of position limiting pile 13 permanent magnet 12 be housed and constitute.The material of position limiting pile 13 is a nonmagnetic substance.
During use this combined little resistance safety check is installed on the water supply line, open water supplying pump (vapour or oil), the valve plate of little resistance safety check is subjected to the thrust of current and opens, two smaller part garden shape iron plates are maintained a certain distance to be held, current are unimpeded, realize little resistance; This moment, the water of little resistance safety check water inlet segment can not enter safety valve from little by-pass pipe because of the effect that little safety check is arranged, and the water of little resistance safety check water outlet pipeline section can not enter safety valve.When pump shutdown, the valve plate of little resistance safety check is closed rapidly under the elasticity return force function of refluence water and offset plate automatically, realizes non-return.When refluence hydraulic pressure surpassed regulation numerical value, safety valve was opened automatically, and fraction refluence water flows back to the water inlet segment of little resistance safety check through the outlet pipe of the water outlet of safety valve, little safety check and safety valve, realizes the earial drainage decompression, the protection pipeline.
Claims (2)
1. combined little resistance safety check that comprises that little resistance safety check, safety valve, little safety check and little by-pass pipe are constituted, it is characterized in that: safety valve is installed on little resistance safety check, the intake pipe of safety valve is installed on little resistance safety check water outlet pipeline section, and the outlet pipe of safety valve is connected on little resistance safety check water inlet segment.
2. combined little resistance safety check according to claim 1 is characterized in that: little safety check is housed on the little by-pass pipe, and the installation direction of its little safety check is the water outlet of the water intake attachment security valve of little safety check.
