Abstract
The utility model provides a combined multifunctional pump control energy saving valve. Through removing a slow closing valve from a multifunctional water pump control valve and equipping on a bypass branch pipe, an overflow amount Q1 of a quick closing valve B is effectively reduced under a precondition that a total flow amount Q is unchanged thereby reducing local loss caused by large overflow amount of the quick closing valve B for obtaining an energy saving effect. The valve is characterized in that the slow closing valve A is mounted parallelly with the quick closing valve B on a main pipe. The slow closing valve A is structurally characterized in that a slow closing shaft 13 of the slow closing valve A is provided with a pressure differential visual rod 1 which passes through the valve top cover 5. A control pipe for a lower chamber of the slow closing valve A is communicated with a threeway main pipe in front of an inlet of the quick close valve B through a pipe fitting, a filter 17, a throttle valve 18 and a pressure control pipe 19 successively. A control pipe for an upper chamber of the slow closing valve A is communicated with a threeway main pipe at a rear end of an outlet of the quick closing valve B through the pipe fitting, the filter 17, the throttle valve 18 and the pressure control pipe 19 successively. The slow closing valve A has the following advantages: simple structure, reliable operation safety, small volume and low cost.
Description
Technical field
The utility model relates to a kind of energy-saving control valve, especially the multifunctional water pump of plumbing control special service valve.
Background technology
At present, known multifunctional water pump control valve all is to be provided with to close the main valve plate soon in a valve, and then in the main valve plate slow-closure type valve is set, and it is characterized in that establishing in the valve valve.The advantage of multifunctional water pump control valve is a compact conformation; The water hammer effect that the elimination termination of pumping causes is remarkable.The deficiency that multifunctional water pump control valve exists is: the internal construction complexity of valve, manufacturing cost height; The water inlet throat of valve is provided with guiding trestle and guide peg reduces the local useful cross section of valve, so hydraulic loss is big.
Summary of the invention
In order to overcome the existing multifunctional water pump control valve complex structure of using, manufacturing cost height; The problem that hydraulic loss is big, the utility model provide a kind of energy-conservation valve of multifunctional assembled pump control with flap valve and termination of pumping elimination water hammer function.Operating principle: fluid pressure energy sharp increase before valve during turn on pump, quick closing valve and Slow Close opening of valves behind the pressure of water in the pipe after overcoming valve, the valve plate of slow-closure type valve A up and down and the pressure balance that enters by pressure control pipe road 19, choke valve 18, strainer 17 of lamina membranacea upper and lower cavity afterwards, but under the effect of pressure differential retinal rod 1, slow-closure type valve A valve open is to maximum.When fault termination of pumping or urgent termination of pumping, quick closing valve B closes soon, return pressure water among the person in charge enters the epicoele of slow-closure type valve A by pressure control pipe road 19, the choke valve of adjusting 18, strainer 17, is zero owing to descend cavity pressure after the termination of pumping, under the upper cavity pressure effect Slow Close valve plate 14 is slowly closed.Thereby reach non-return and eliminate the effect that termination of pumping produces water hammer.Energy-saving principle is: there is local head loss in the valve in the pipeline in the process of carrying fluid, fluid by local head loss's common-used formula that channel bend and valve caused is:
(1) ζ in the formula-local head loss's coefficient, V-enters the fluid average speed of valve, g-acceleration of gravity (9.81m/S
2).Because flow velocity
Its substitution formula (1) is obtained:
-(2), can reach a conclusion by the deformation type (2) of local head loss's formula: the h of local head loss and flow Q by valve square are directly proportional; With square being inversely proportional to of the overflow section A of valve.The energy-conservation valve of multifunctional assembled pump control is exactly by by-pass shunt Q
2With increase area of passage A and realize energy-conservationly, make local head loss
Effectively reduce and energy-conservation.
The technical scheme that the utility model adopted is: one, comprise slow-closure type valve A, quick closing valve B, it is characterized in that: slow-closure type valve A is by arm and the quick closing valve B aggregate erection of being responsible in parallel.Two, but the Slow Close axle 13 of slow-closure type valve A is provided with pressure differential retinal rod 1 inside and outside valve top cover 5.Three, the control piper of slow-closure type valve A cavity of resorption is by pipe fitting, strainer 17, and the threeway that choke valve 18, pressure control pipe road 19 connect in turn before quick closing valve B import is responsible for; The control piper of slow-closure type valve A epicoele is by pipe fitting, strainer 17, and choke valve 18, pressure control pipe road 19 connect in turn in the threeway of quick closing valve B outlet rear end and be responsible for.
The beneficial effects of the utility model are: be installed on the bypass arm by the slow-closure type valve in the multifunctional water pump control valve being shifted out and simplifying, the inflow-rate of water turbine that has reduced quick closing valve B under the constant prerequisite of total flow Q effectively is Q1, thereby reduces the local losses h that the main valve inflow-rate of water turbine causes greatly.And slow-closure type valve is simple in structure, and is safe and reliable to operation, and volume is little, cost is low.
