Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-3, a flow limiting device for water supply and drainage in an automatic control system of building equipment comprises a shell 1, wherein a water inlet pipe 2 and a water outlet pipe 3 are respectively welded and fixed on two sides of the shell 1, an emergency pipeline 4 is hermetically and slidably connected in the shell 1, two fixed blocks 5 are symmetrically welded and fixed on the upper side of the emergency pipeline 4, a ball valve 6 is fixedly connected on the upper sides of the two fixed blocks 5 through bolts and nuts, two ends of the ball valve 6 are respectively communicated with the water inlet pipe 2 and the water outlet pipe 3, the ball valve 6 and the fixed blocks 5 are both hermetically and slidably connected with the shell 1, a first chute 7 is formed in the upper side of the shell 1, and a lifting mechanism is.

Hoist mechanism includes and uses the screw rod 8 that the bearing rotated to be connected with first spout 7, threaded connection has slider 9 on the screw rod 8, open 7 one side of first spout has logical groove 10 with the inside intercommunication of casing 1, it has slide bar 11 to lead to sliding connection in groove 10, slide bar 11 one end and slider 9 welded fastening, the slide bar 11 other end and 5 welded fastening of fixed block, screw rod 8 drives ball valve 6 and emergent pipeline 4 upward movement, make ball valve 6 when carrying out maintenance work, emergent pipeline 4 and inlet tube 2, outlet pipe 3 intercommunication, make can not cause economic loss or bring the life inconvenience for the resident because of the maintenance.

One side welded fastening that fixed block 5 kept away from slide bar 11 has dead lever 12, it has second spout 16 to open on the casing 1 is close to one side inner wall of dead lever 12, dead lever 12 slides in second spout 16, dead lever 12 supports ball valve 6 with slide bar 11 jointly and slides and keep the level in casing 1, prevent emergent pipeline 4 because automatic action of gravity takes place the slope, thereby influence emergent pipeline 4 and inlet tube 2, the sealed connectivity of outlet pipe 3, prevent the hourglass water.

The dead lever 12 is opened flutedly 13 in the gliding one side of second spout 16, horizontal welded fastening has spring 14 in the recess 13, spring 14 welded fastening has wedge 15, the one side of dead lever 12 is kept away from to second spout 16 upper end is opened has spacing hole 17 with wedge 15 matched with, when dead lever 12 slides in second spout 16 and makes recess 13 and spacing hole 17 communicate, wedge 15 outwards stretches out under spring 14's elastic force and cooperatees with spacing hole 17, thereby fix ball valve 6, make things convenient for the staff to carry out maintenance work to the valve body.

The radius of the cross sections of the water inlet pipe 2 and the water outlet pipe 3 are the same, and the radius of the cross section of the emergency pipeline 4 is larger than that of the cross sections of the water inlet pipe 2 and the water outlet pipe 3.

The horizontal width of fixed block 5 is greater than inlet tube 2, outlet pipe 3's cross section diameter, and ball valve 6 is at the upward movement in-process, and inlet tube 2, outlet pipe 3 offset respectively with two fixed blocks 5 and do not communicate with casing 1 is inside for ball valve 6 is at the upward movement in-process, and rivers can not follow inlet tube 2, outlet pipe 3 and flow to casing 1 in,

corrode ball valve

6 and 4 outer walls of emergent pipeline, thereby influence whole device life-span.

In the utility model, when the ball valve 6 needs to be disassembled, replaced and maintained, the worker rotates the screw 8 to enable the sliding block 9 to slide upwards in the first sliding groove 7 to drive the sliding rod 11 to slide upwards, the sliding rod 11 drives the ball valve 6 to slide upwards in the shell 1 through the fixed block 5, the fixed rod 12 slides upwards in the second sliding groove 16 under the action of the fixed block 5, the wedge 15 abuts against the inner wall of the second sliding groove 16 and compresses the spring 14, the fixed rod 12 and the sliding rod 11 support the ball valve 6 to slide and keep horizontal in the shell 1 together, the emergency pipeline 4 is prevented from inclining due to the automatic gravity action, thereby the sealing connectivity between the emergency pipeline 4 and the water inlet pipe 2 and the water outlet pipe 3 is influenced, water leakage is prevented, when the ball valve 6 moves upwards, the two fixed blocks 5 abut against the water inlet pipe 2 and the opening of the water outlet pipe 3 respectively, water flow outflow is prevented, when the fixed rod 12 slides in the second sliding groove, the wedge block 15 extends outwards under the elastic force of the spring 14 to be matched with the limiting hole 17.

Emergent pipeline 4 at this moment replaces ball valve 6 and

inlet tube

2, 3 intercommunications of outlet pipe and ball valve 6 move to the casing outside, because wedge 15 cooperatees with spacing hole 17, continue to rotate screw rod 8 and also can't drive ball valve 6 upward movement, thereby fix ball valve 6, make things convenient for the staff to work the valve body, realized the staff and maintaining the change during operation to the valve body, need not to close the master switch, keep the water supply line unblocked, prevent to bring inconvenience or cause economic loss to resident's life.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
