Description
The utility model relates to a kind of waterworks, particularly a kind of fire-fighting and common water supply self-balancing gas compensating type pressurized-type water supply unit.
The utility model is to be to application number: " 96216037.7 ", name is called: the improvement of " the full-automatic self-balancing gas compensating type of mechanical type pressurized-type water supply unit " patent.Because surplus gas compensating type water supply facilities is used in and makes the water pump frequent starting in the common water supply, the volume of regulation and stipulation surplus gas compensating type auto-pneumatic cylinder should multiply by the coefficient of 1.5-2 for this reason.And self-balancing gas compensating type auto-pneumatic cylinder air capacity can not increase, so coefficient is 1, therefore can reduce the auto-pneumatic cylinder volume.General self-balancing gas compensating type pneumatic installation water supply needs with more appliance controller, electromagnetic valve, and equipment has increased, and the quality of these equipment is stable inadequately, and influence is normally used.Documents has proposed new technical scheme, mainly air supply tank, one way valve, pipeline etc. are improved, constitute the full-automatic self-balancing gas compensating type of mechanical type pressurized-type water supply unit, on this basis, the structure of its air supply tank, the dual-purpose one way valve of air water still can further be improved, and makes that structure is simpler, function is more stable.
The purpose of this utility model provides a kind of self-balancing gas compensating type pressurized-type water supply unit.It can guarantee that fire pump starts the water yield in the auto-pneumatic cylinder, rationally controls air compensation; And further optimize the structure of air supply tank, the dual-purpose one way valve of air water, install simplyr, it is more reliable to turn round, and reduces the operation troubles rate.
The purpose of this utility model is achieved in that
A kind of self-balancing gas compensating type pressurized-type water supply unit, it comprises: water tank, water pump, air supply tank, air entry, auto-pneumatic cylinder, pressure sensing device; By pipeline water tank, water pump, air supply tank, auto-pneumatic cylinder are connected, on the pipeline between air supply tank and auto-pneumatic cylinder, be provided with the dual-purpose one way valve of air water, be fixed with sealing ring on the water inlet of described air supply tank, be provided with barrier above the sealing ring, the barrier end face is provided with cover plate, and the cover plate inner face has rubber cushion, is provided with ball float in the barrier, ball float is spacing near sealing ring with barrier, with sealing ring fitted seal or unlatching.
The structure of the dual-purpose one way valve of described air water is: the upper and lower bottom surface of valve body is fixed with sealing ring, rubber cushion, the centre is provided with spool, spool is that lightweight is spherical or cylindrical, be provided with spacing barrier or valve interior wall in the valve body and have groove or fin, spool is spacing and can allow water, air communication, spool and sealing ring fitted seal or unlatching, have tank on the rubber cushion, when spool contacted with rubber cushion, water was circulated by tank, and described spool is preferably spherical ball float or cylindrical ball float.
The utility model has following advantage and good effect: it is used in the common water supply, reduces tank body volume 0.5-1 doubly than surplus gas compensating type auto-pneumatic cylinder, and water pump frequent starting problem also is resolved.Its structure is simpler, and the moving component of air supply tank, the dual-purpose one way valve of air water can have only ball float, so the possibility that breaks down reduces greatly, it is more reliable to turn round, and cost of production decreases, and is easier to promote the use of.

Describe the utility model in detail below in conjunction with drawings and Examples.
As shown in Figure 1, it comprises: water tank 1, water pump (or stabilized pressure pump) 2, air supply tank 3, air entry 5, the dual-purpose one way valve 6 of air water, auto-pneumatic cylinder 7, U type water seal 8.Auto-pneumatic cylinder is provided with pressure meter, and links with water pump, when the pressure in the auto-pneumatic cylinder reaches turn on pump pressure or termination of pumping pressure, and water pump Auto Power On or shutdown.P3 is a water pump turn on pump pressure, and P4 is a water pump termination of pumping pressure, and P4 is a control water level.During as common water supply, P1 is a starting mode of pump pressure, and P2 is a termination of pumping pressure, and the P2 water level is a control water level, and the water level control accuracy is a benchmark with the termination of pumping water level all.Shown in Fig. 2-3, to make precision very high for ball float 401 in this air supply tank, and stopping means is arranged, i.e. barrier 404 and cover plate 405, and the cover plate inner face also can have rubber cushion 403, and ball float is moved within the specific limits, unlikely left and right sides sideslip; When the jar middle water level is high, the ball float come-up, float valve 4 is opened, during termination of pumping, the air supply tank middle water level descends, and drawdown is during to certain water level, and ball float falls, ball float and sealing ring 402 fitted seal, sealing ring is preferably rubber ring, and float valve is closed, and water no longer outflows, and forms water seal.
Electromagnetic valve quality is relatively poor at present, use safety inadequately, if adopt the high-quality electromagnetic valve, be installed on the pipeline that is connected between water pump and air supply tank, in air supply tank, establish a level electrode 408 (also can not establishing), and interlock with water pump, electromagnetic valve 407 was opened when water pump left, water pump treats when closing that water level is reduced to the level electrode place in the blowdown pipe and cuts out electromagnetic valve, also can test the electromagnetic valve delayed start-up time after termination of pumping of adjusting at the scene, just can realize the quantitative draining purpose of air supply tank, this also is the another embodiment of the utility model air supply tank, as shown in Figure 7.
Shown in Fig. 4-6, on the valve body of the dual-purpose one way valve 6 of air water, bottom surface is fixed with sealing ring 601, rubber cushion 602, the centre is provided with spool 603, spool can be done globulate or cylindrical, be preferably spherical ball float, spacing and water through barrier 607 is arranged outside spool, be commonly called as the gaily decorated basket, can make water, gas circulates between spool and valve body, as not establishing the gaily decorated basket, also can open several grooves 604 or have fin 605, so that make gas at valve interior wall, current are logical, spool and sealing ring fitted seal or unlatching, have tank 606 on the rubber cushion 602, when spool contacted with rubber cushion, water was circulated by tank, do overtesting the sixth of the twelve Earthly Branches, respond well.
Principle in view of the above, the mobilizable flap valve of spool, liquid level automatic control valve all can be made the air water dual-purpose valve and use.This air water dual-purpose valve also can cooperate by electromagnetic valve, with level electrode and reach the purpose that sealing is ventilated, and level electrode is located in the auto-pneumatic cylinder, than the high 0.5-1cm of design peak level place.When water level reached the electrode place, the level electrode control electromagnetic valve was closed, and made air supply tank from outside tonifying Qi, and reached the purpose of balance tonifying Qi.
The detailed operation principle of self-balancing tonifying Qi and correlation technique are open in documents the sixth of the twelve Earthly Branches, so do not giving unnecessary details.
