Description
Technical Field
The invention relates to a reverse blocking device of a water pump check valve, in particular to a butterfly bivalve check valve.
Background
In the chilled water and cooling water system of heating and ventilating air conditioner, a check valve which allows water flow to move in one way is installed at the outlet of a water pump, the check valve can be closed quickly when the water pump stops to prevent water flow from flowing back and generating water hammer, the butterfly-shaped double-flap check valve is composed of a valve body, a valve flap 1, a valve flap 2 and a spring, the valve flap 1 and the valve flap 2 are in a closed state under the counterforce of the spring, when the water pump starts water flow to impact the valve flap, the impact force of the water flow is greater than the counterforce of the valve flap spring, the valve flap is opened slowly until 90 degrees are all opened, once the valve flap is opened, the spring of the valve flap always generates a closing acting force on the valve flap, the water flow finally acts on the water flow and the counterforce of the spring is overcome at any time, therefore, one part of the power consumption of the, because the lift of the water pump is reduced rapidly along with the reduction of the frequency of the motor, but the resistance of the one-way valve is still overcome at the moment, the space for reducing the frequency is reduced, and the operation cost cannot be saved to the maximum extent.
The butterfly bivalve check valve has the following disadvantages: the valve clack is as long as open no matter the angle size all receives the reaction force of spring, and rivers have also born spring reaction force when the valve clack this moment passes through, and when the valve clack opening angle was little, rivers not only received the reaction force of spring, and valve clack itself has also blockked rivers simultaneously, forces the water pump to increase the rotational speed and overcomes above-mentioned resistance, is unfavorable for the energy-conserving operation of water pump.
Disclosure of Invention
In order to overcome the reverse acting force of the valve clacks of the butterfly-shaped double-clack one-way valve and the spring on water flow, the invention provides a reverse resistance device of the butterfly-shaped double-clack one-way valve, which removes the resistance of the butterfly-shaped double-clack one-way valve by clamping the valve clacks.
The technical scheme adopted by the invention for solving the technical problems is as follows: a butterfly-shaped double-flap check valve reverse blocking device comprises a push-pull type traction electromagnet, a rocker with a V-shaped opening, a stainless steel woven soft joint and an outer wire short joint, wherein the butterfly-shaped double-flap check valve reverse blocking device drives the V-shaped opening rocker to swing under the action of the push-pull type traction electromagnet, the resistance of a butterfly-shaped double-flap check valve is relieved through the V-shaped rocker, the V-shaped opening rocker is connected with the push-pull type traction electromagnet through a movable bolt, one end of a stainless steel woven hose is welded and sealed with the V-shaped opening rocker, the other end of the stainless steel woven hose is connected with the outer wire short joint welded on a pipeline through a nut, the V-shaped opening rocker is connected with a steel wire handle of the outer wire short joint to generate a limiting movable fulcrum, and the V-shaped opening rocker can swing under the action of the limiting movable. When the electromagnet is powered off, the V-shaped opening rocker is under the action of the electromagnet spring to separate the V-shaped opening from the valve clack, and the valve clack is closed fast under the action of the spring to realize the action of one-way reverse flow.
The invention has the advantages that under the action of the push-pull type traction electromagnet, the valve clack of the butterfly double-clack one-way valve is fixed in an opening state through the swinging of the V-shaped port rocker, the reaction force used for closing the valve clack spring is subjected to reverse resistance, no reaction force is generated on water flow, the valve clack can still be opened at 90 degrees when the water pump is subjected to frequency reduction, the resistance on the water flow is reduced, the frequency conversion space of the water pump is improved, and the operation power consumption of the water pump is reduced. When the water pump is closed, the power supply of the electromagnetic valve can be closed in advance through a program, the rocker releases the limitation on the valve clack under the action of the spring of the electromagnetic valve, and the one-way valve clack can be closed in time according to the stop of water flow under the action of the spring of the rocker, so that the effects of preventing water hammer and backflow are achieved.

Detailed Description
[ example 1 ]
When the butterfly-shaped double-flap one-way valve 11 is opened by 90 degrees, the V-shaped opening rocker 4 swings the V-shaped bayonet 7 to the two sides of the valve clack to clamp the valve clack under the action of the push-pull type traction electromagnet 2, the V-shaped bayonet 7 completely limits the valve clack to remove the reaction force of the valve clack spring 14, the resistance of the butterfly-shaped double-flap one-way valve 11 to the water pump is completely removed, particularly when the water pump operates at low speed (frequency reduction), the lift of the water pump is greatly reduced at the moment, and the water pump can use all the lifts for water supply after the resistance of the butterfly-shaped double-flap one-way valve 11 is removed. When the water pump stops, the power supply of the push-pull type traction electromagnet 2 is cut off in advance under the action of an automatic control program as shown in fig. 3, the V-shaped opening rocker 4 swings reversely under the action of the electromagnet spring 3, the V-shaped bayonet 7 is separated from the valve clack, and the valve clack is closed along with the stop of water flow under the action of the valve clack spring 14, so that the effects of preventing water flow from flowing back and preventing water hammer are achieved.
