Description
Technical field
The utility model relates to a kind of pump, specifically is a kind of pump of cutting off the water supply.
Background technique
In the family expenses pure water machine system, usually be equipped with when suction booster and the solenoid valve of cutting off the water supply come system carried out supercharging and shut down and cut off the water supply.The employing solenoid valve of cutting off the water supply carries out water route control, and cost is higher, installations is complicated, and there are circuit and pipeline and deposit, and the restriction of the peculiar structure of solenoid valve of being cut off the water supply, its reliability that water route is controlled is not high.In order to overcome the deficiency of the solenoid valve of cutting off the water supply; People adopt the pump of cutting off the water supply to replace the solenoid valve of cutting off the water supply to come the break-make in water route in the pure water machine system is controlled; Yet the existing pump vibrations when output hydraulic pressure is lower than former water hydraulic pressure of cutting off the water supply are bigger; Pipeline comes off in the pure water machine system thereby be prone to cause, and is prone to influence the working life of the pump of cutting off the water supply.
The model utility content
The purpose of the utility model is to overcome the deficiency of existing technology, provides a kind of and has been lower than the pump of cutting off the water supply with shock-absorbing function that can reduce vibrations when former water hydraulic pressure moves at output hydraulic pressure.
The purpose of the utility model mainly realizes through following technological scheme: the pump of cutting off the water supply with shock-absorbing function; Comprise the pump head that has former water cavity and hyperbaric chamber in it; Pump head is provided with the water intake of connecting former water cavity and the water outlet of connecting hyperbaric chamber; Said pump head is sealedly connected with capping, is provided with pressure-sensitive diaphragm between pump head and the capping, and the pressure-sensitive diaphragm periphery is sealedly attached between pump head and the capping; Constitute the water shutoff chamber of connecting former water cavity between pressure-sensitive diaphragm and the capping; Be provided with the spring that two ends act on capping inner top and pressure-sensitive diaphragm respectively in the water shutoff chamber, constitute the water chamber of connecting hyperbaric chamber and water outlet between pressure-sensitive diaphragm and the pump head, pump head constitutes the water shutoff mouth of connecting hyperbaric chamber and water chamber; Pressure-sensitive diaphragm sealing water shutoff mouth, pressure-sensitive diaphragm in hyperbaric chamber in hydraulic pressure, the water shutoff chamber in hydraulic pressure, the water chamber acting in conjunction of hydraulic pressure and spring constitute down control the water-breaking structure that change in the water route between hyperbaric chamber and the water chamber under the switching two states; Said pressure-sensitive diaphragm is connected with the damping member that moves hydraulic pressure in the hyperbaric chamber through pressure-sensitive diaphragm.The utility model is not when starting, and water shutoff chamber internal water pressure surpasses the preset elastic force acting in conjunction of interior water pressure partial action power of hyperbaric chamber and water chamber and spring in the water shutoff mouth, makes the water shutoff mouth be in the water shutoff state; When the utility model starts; Hydraulic pressure in the hyperbaric chamber increases; Hydraulic action in hyperbaric chamber and the water chamber in the force water shutoff chamber of pressure-sensitive diaphragm hydraulic pressure and spring to the active force of pressure-sensitive diaphragm; Thereby water chamber and hyperbaric chamber are connected, and the current in the hyperbaric chamber can be discharged through water chamber and from water outlet.When the utility model was shut down, the hydraulic pressure in the hyperbaric chamber reduced, in the water shutoff chamber hydraulic pressure and spring to the force hyperbaric chamber of pressure-sensitive diaphragm and the hydraulic action in the water chamber in the active force of pressure-sensitive diaphragm, thereby make pressure-sensitive diaphragm seal the water shutoff mouth gradually.
Said water shutoff is provided with the backing plate that is connected with pressure-sensitive diaphragm in the chamber, said spring action in an end apical grafting of pressure-sensitive diaphragm on backing plate.
A kind of mode of execution as the utility model; Said damping member comprises the damping piece one that is arranged in the hyperbaric chamber; Damping piece one is connected with pressure-sensitive diaphragm; Form the damping slit of connecting the water shutoff mouth between the outer side wall of damping piece one upper end and the sidewall of hyperbaric chamber, damping piece one is provided with the runner four of connecting damping slit and hyperbaric chamber.The utility model damping member adopts this mode of execution; Shutting down or output hydraulic pressure when being lower than former water hydraulic pressure, damping piece one moves to the direction of hyperbaric chamber, and the damping slit is elongated; The suffered resistance of current that gets into water chamber from hyperbaric chamber becomes big; Build the pressure in the hyperbaric chamber, hydraulic pressure raises again in the hyperbaric chamber, thereby reduces the speed of pressure-sensitive diaphragm sealing water shutoff mouth.The pressure-sensitive diaphragm that quick pressure releasing was caused in the hyperbaric chamber when the utility model was not provided with damping member seals the water shutoff mouth rapidly, and the utility model can slow down the travelling speed of pressure-sensitive diaphragm, thereby causes than big bang when avoiding pressure-sensitive diaphragm to touch the water shutoff mouth.
The end face evagination that said pressure-sensitive diaphragm contacts with water chamber constitutes end socket, and said pressure-sensitive diaphragm is through end socket sealing water shutoff mouth.
Another kind of mode of execution as the utility model; Said damping member comprises the damping piece two that is arranged in the water chamber; Damping piece two is connected with pressure-sensitive diaphragm; Form the damping slit of connecting the water shutoff mouth between the outer side wall of damping piece two upper ends and the madial wall of water chamber, damping piece two is provided with the runner five of connecting damping slit and water chamber.The principle of this mode of execution is identical with the principle that damping piece one is set in hyperbaric chamber; The both is shutting down or output hydraulic pressure when being lower than former water hydraulic pressure; Build the pressure in the hyperbaric chamber and slow down moving of pressure-sensitive diaphragm, difference between the two is: damping member comprises damping piece for the moment, and damping piece one moves in hyperbaric chamber; When damping member comprised damping piece two, damping piece two moved in water chamber.
The utility model compared with prior art has the following advantages and beneficial effect: the utility model seals the water shutoff mouth through pressure-sensitive diaphragm; The water shutoff mouth constitutes water-breaking structure under the effect of hydraulic pressure and spring in hydraulic pressure, the water shutoff chamber in hydraulic pressure, the water chamber in hyperbaric chamber; The pressure-sensitive diaphragm of the utility model also is connected with the damping member of regulating hydraulic pressure in the hyperbaric chamber through moving of pressure-sensitive diaphragm; So; The utility model is shut down or output hydraulic pressure when being lower than former water hydraulic pressure, and the vibrations that the utility model occurs are little.
