Abstract
The utility model provides a water escape valve device with adjustable spring force. The water escape valve device comprises a valve body, a lower cover, a water escape valve plate, a lower valve base and an anti-splashing cover, wherein the lower cover is fixed below the valve body, the water escape valve plate is arranged inside the valve body and above the lower cover, the lower valve base is provided with a through hole which is blocked at the end opening position of the lower cover, and the water escape valve device further comprises a water escape groove and an adjusting spring. One end of the adjusting spring is fixed at the bottom of the lower valve base, the other end of the adjusting spring is fixed at the bottom of a cylindrical groove of the half lower portion of the water escape groove, an adjusting nut is arranged at the bottom of the lower valve base and is connected with the side wall of the lower valve base through a thread, the depth of the lower valve base can be changed by rotating, and therefore, pressure of the adjusting spring is changed. The water escape valve device with the adjustable spring force has the advantages that with the technical scheme, pressure of the adjusting spring can be adjusted, and according to different working conditions, opening differential pressure of the water escape valve can be randomly adjusted so as to meet requirements for different working conditions.
Description
Technical field
The utility model relates to a kind of drain valve, especially relates to a kind of drain valve device of adjustable spring power.
Background technique
Drain valve is playing vital effect as the significant components of backflow preventer aspect anti-medium refluence, and when medium refluence or import decompression occured, drain valve must be opened rapidly intermediate cavity water or refluence water are discharged, the safety of assurance pipe network.The unlatching of drain valve determines by spring force, and the unlatching spring force of general drain valve is fixed, and is relatively poor to the adaptive capacity of operating mode, easily causes opening having some setbacks or drain valve water clock in service, is badly in need of now a kind of drain valve device that can regulate starting differential pressure.
The model utility content
The purpose of this utility model is to provide a kind of drain valve device of simple in structure, safe and reliable adjustable spring power.
the technical solution of the utility model is: a kind of drain valve device of adjustable spring power, comprise valve body, lower cover, the sluicing valve plate, lower valve base and splash guard, described lower cover is fixed on below described valve body, described sluicing valve plate is positioned at described valve inner, and be positioned at above described lower cover, described lower valve base is with through hole, get lodged in the port of described lower cover, described splash guard is fixed on the port periphery of described lower cover, also comprise drain tank and Regulation spring, described drain tank is formed by stacking by small one and large one concentric two cylinders, with central through bore, the first half of described drain tank is small column, circular hole below described sluicing valve plate stretches into and is fixed by nut, described drain tank first half outer wall is provided with some annular seal grooves with rubber ring, the Lower Half of described drain tank is big column, and the below is with cylinder shape groove, be communicated with central through bore, the Lower Half of described drain tank stretches in described lower valve base, one end of described Regulation spring is fixed on the bottom of described lower valve base, the other end is fixed on the Lower Half cylinder shape groove bottom of drain tank, the bottom of described lower valve base is for reconciling locknut, be connected with the sidewall of described lower valve base by screw thread, can change by rotation the depth of described lower valve base, thereby change described Regulation spring pressure.
Preferably, be distributed with some water ports on described conciliation locknut.
Preferably, be lined with packing ring between described conciliation locknut and described Regulation spring.
Advantage and the good effect that the utlity model has are:
Owing to adopting technique scheme, the Regulation spring pressure is adjustable, just can arbitrarily regulate the starting differential pressure of drain valve according to different operating modes, satisfies the demand of different operating modes.
