Abstract
The utility model relates to a novel transmission multifunctional water power control valve, which is composed of a main valve and an in and out bypass pipeline, wherein the main valve is composed of a Y-shaped valve body, a valve seat, a valve cover, a diaphragm, a main valve rod, a main valve plate, a slow closure valve rod, a slow closure valve plate, a spring, etc. The structure leads the valve to have the characteristics of large overflowing quantity, little pressure loss and strong cavitation damage resistant capability. In addition, the utility model can stably stop water and close, and can not generate water hammers.
Description
Affiliated technical field
The utility model relates to a kind of novel transmission multifunctional water force control valve.
Background technique
Safety check is used very extensive in all kinds of transporting systems.The check valve structure form mainly contains Swing check valve at present, heavy hammer type returns valve, micro-resistance slowly-closed butterfly check valve etc.Swing check valve is not because structural reason has the Slow Close function, as the unexpected termination of pumping of the system that runs into, and then valve plate returns to close and may produce very big impact of water hammer, and the safety of water pump and pipe network is caused very big harm; Heavy hammer type safety check and micro-resistance slowly-closed butterfly check valve since counterweight equilibrant and the axle surface friction drag of side and the oil hydraulic cylinder of hydraulic control easily have leakage phenomenon, therefore can't reach and close soon and the Slow Close function, especially can't solve because of having a power failure suddenly, control valve can not in time return to close or be not closed completely and cause the impact of pipeline medium to water-raising system.
Summary of the invention
The purpose of this utility model is to adopt a kind of novel transmission multifunctional water force control valve, can effectively solve the water hammer that produces when water pump is shut down to the impact of system, prevent that medium from flowing backwards, having and close soon and the Slow Close function.
The technological scheme that addresses the above problem is that the structure of whole valve adopts Y valve body and two chambers diaphragm drive means.Valve is made up of the main valve and the bypass line of coming in and going out, and main valve is made up of critical pieces such as Y valve body, valve seat, valve gap, barrier film, main valve stem, main valve plate, Slow Close valve rod, Slow Close valve plate and springs.Y valve body, valve seat, valve gap, barrier film are fixedly connected, and barrier film and main valve stem are fixedly connected, and valve seat and main valve stem are the suit state; The inlet bypass line communicates with water-inlet cavity and barrier film cavity of resorption, and the outlet bypass line communicates with water chamber and barrier film epicoele; Spring housing is contained on the main valve stem, and its both ends of the surface prop up valve seat and main valve plate respectively; Slow Close valve rod and main valve plate are fixedly connected, and main valve stem and Slow Close valve plate are sleeved on outside the Slow Close valve rod, also compress with the non-magnetic shim bolt with scyewed joint between Slow Close valve plate and the main valve stem.Adopt this structure to make valve have the advantages that inflow-rate of water turbine is big, the pressure loss is little, the anti-cavitation damage capability is strong, steadily sealing is closed, and does not produce water hammer.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the partial enlarged drawing of Fig. 1.
Embodiment
As shown in the figure, the utility model is made up of Y valve body 3, valve seat 4, valve gap 7, barrier film 5, main valve stem 8, main valve plate 11, spring 10, Slow Close valve rod 15, Slow Close valve plate 14, inlet bypass line 13, outlet bypass line 1, Y valve body 3, valve seat 4, valve gap 7, barrier film 5 are fixedly connected, barrier film 5 is fixedly connected with main valve stem 8, and valve seat 4 is the suit state with main valve stem 8; Inlet bypass line 13 communicates with water-inlet cavity 12 and barrier film cavity of resorption 9, and outlet bypass line 1 communicates with water chamber 2 and barrier film epicoele 6; Spring 10 is sleeved on the main valve stem 8, and its both ends of the surface prop up valve seat 4 and main valve plate 11 respectively; Slow Close valve rod 15 is fixedly connected with main valve plate 11, main valve stem 8 and Slow Close valve plate 14 are sleeved on outside the Slow Close valve rod 15, also compress with scyewed joint between Slow Close valve plate 14 and the main valve stem 8 with the non-magnetic shim bolt, so both avoided the Slow Close valve plate to connect the phenomenon that easily produces processing difficulties and welding deformation by welding with main valve stem, the Slow Close valve plate is closed enter Slow Close during the stage, motion class between Slow Close valve plate and the Slow Close valve rod is like the motion of hydraulic piston cylinder, functional and the steady sealing of self poisoning, the anti-cavitation damage capability is strong.Main valve plate 11 has been established discharge orifice 16.
The concrete working principle of valve is as follows: during starting mode of pump, feed-water end pressure imports barrier film cavity of resorption 9 into by inlet bypass line 13, main valve plate 11 and Slow Close valve plate 14 are slowly opened under the double action of feed-water end pressure and barrier film cavity of resorption hydraulic pressure, and its valve opening is determined by flow.During termination of pumping, flow and pressure reduce suddenly, main valve plate 11 begins downward landing under the effect of self gravitation and spring 10, main valve plate 11 is closed when flow system flow approaches zero, because discharge orifice 16 effects are not to close fully, has reduced impact of water hammer like this, valve export hydraulic pressure enters barrier film epicoele 6 from outlet bypass line 1 and promotes barrier film 5 simultaneously, main valve stem 8 drives Slow Close valve plate 14 to begin to close, and enters the Slow Close stage, until closing fully.
