Abstract
The utility model relates to a one way valve with a guiding cylinder and a floating ball, which solves the problems of short service life and large noise by the continuous knock between floating balls and valve seats, valve bodies and honeycomb ducts existing in the present one way valves. The lower part of the honeycomb duct in a valve body is additionally provided with a guiding cylinder for a floating ball, and a cone-shaped duct segment is arranged on the inner wall of the lower part of the valve body, so the floating ball can be stably absorbed on the sealing surface of the honeycomb duct, and the impact can not be generated by the floating ball to the honeycomb duct, the valve seat, the valve body, etc. The utility model eliminates the noise generated by the knock in the past and extends the integral service life of the one way valve.
Description
The utility model is a kind of guiding cartridge type ball float deadweight one-way valve that is installed on the pipeline.
Existing one-way valve, in valve body, there is not guide cylinder, valve body lower portion does not have the Taper Pipe section, thereby have following point: 1, the circulation area at ball float place is greater than the circulation area at honeycomb duct place, the pressure that forms in the ball float both sides falls less than the pressure at the honeycomb duct entry end and falls, and ball float effectively stably is being adsorbed on the honeycomb duct in the pressure reduction, but does upper and lower to-and-fro motion between honeycomb duct and valve seat, thereby, constantly clash into valve seat, valve body, honeycomb duct; 2, because the continuous variation of flow, make ball float can not tightly be attached to the ingress of honeycomb duct, but near honeycomb duct upper and lower beating, after ball float impinges upon on the honeycomb duct,, ball float is rebounded down again because pressure difference is not enough to the gravity and the rebounding force of balance ball float, impinge upon on valve body and the valve seat, and fluid holds up ball float once more, goes round and begins again, and produces continuous bump.Thereby noise is big, makes the working life of one-way valve very low.
The purpose of this utility model is, solves existing existing problem, and a kind of guiding cartridge type ball float deadweight one-way valve of long service life is provided.
The utility model is achieved in that the upper and lower end of valve body is separately installed with German-style metal lensring, following German-style metal lensring, and ball float is placed on down on the German-style metal lensring; Honeycomb duct is installed on the German-style metal lensring by screw thread; The flange that install in the outside of upper and lower adapter makes the whole valve body location by bolt, nut.In valve body, the ball float guide cylinder is set up in the bottom of honeycomb duct, is provided with the Taper Pipe section at the valve body lower portion inwall.
Advantage of the present utility model is that in valve body, the ball float guide cylinder is set up in the bottom of honeycomb duct, is provided with the Taper Pipe section at the valve body lower portion inwall.Make minimum critical flow less than actual flow, actual fluid flow rate is greater than minimum critical flow velocity, by the kinetic pressure of fluid generation, the gravity that supporting power sum is far longer than ball float.Therefore, ball float can be stablized on the sealing surface that is adsorbed on honeycomb duct, does not impact and honeycomb duct, valve seat, valve body etc. are not produced.The noise of having eliminated collision in the past and having produced has prolonged the working life of one-way valve integral body.
The drawing explanation:
Fig. 1 is a structural representation of the present utility model;
Describe in detail below in conjunction with accompanying drawing:
As shown in the figure, the upper and lower end of valve body 7 is separately installed with German-style metal lensring 5, following German-style metal lensring 9, and ball float 8 is placed on down on the German-style metal lensring 9; Honeycomb duct 6 is installed on the German-style metal lensring 5 by screw thread; The flange 4 that install in the outside of upper and lower adapter 1 makes the whole valve body location by bolt 2, nut 3.In valve body 7, ball float guide cylinder 6A is set up in the bottom of honeycomb duct 6, is provided with Taper Pipe section 7A in valve body 7 lower inner wall.
