Abstract
The utility model discloses a vertical check valve, which is a flow control device, overcoming the defects existing in the prior art. The vertical check valve is composed of a valve body, a valve seat and a sealing ball, wherein the sealing ball is in the valve body and vertically mounted on a liquid inlet of a pipeline; the valve body and the valve seat are connected by screw threads; the top end of the valve body is provided with a liquid outlet, the bottom of the liquid outlet is provided with a baffle, the middle part of the baffle is provided with a liquid drainage central hole, 6 liquid outlets are uniformly distributed around the liquid drainage central hole; the bottom face of the valve seat is provided with a liquid inlet; when using, the inlets and outlets can be configured into screw threads or flanges to be mounted in the vertical direction so as to prevent liquid backflow. 6 liquid outlets are uniformly distributed around the outlet to prevent the sealing ball from being projected to block the liquid outlet; the sealing ball is mounted in the valve body and the valve seat, and then vertically installed on the pipeline, when liquid flows from the valve seat at the bottom, the liquid ejects the sealing ball and flows out; if the pressure of the liquid is not enough, the sealing ball falls down onto the valve seat to seal the inlet so as to prevent liquid at the outlet from flowing back.
Description
One, technical field: the utility model relates to a kind of fluid control device, especially rectilinear one-way valve.
Two, background technique: one-way valve can be controlled the fluid individual event and flow as a kind of device of fluid control, guarantees that fluid does not flow backwards, and is widely used in the productive life.Commonly used is horizontal rotary-open type or disc-type at present, and it has complex structure, processing technology requires characteristics such as height.Above one-way valve exists following problem and narrow limitation using and manage: the one, and it is big that narrow limitation is installed, and can only horizontal install; The 2nd, spool is corroded or is damaged, and integral body is scrapped, cost of idleness: the 3rd, and volume is big, is not easy to install.
Three, summary of the invention: the purpose of this utility model provides a kind of long service life, the rectilinear one-way valve that can install in vertical place, it has overcome the defective that above-mentioned prior art exists, the purpose of this utility model is to realize like this, it is by valve body and valve seat, the ball sealer three parts are formed, and ball sealer is positioned at valve body, and is vertically mounted on the liquid entering hole of pipeline; Valve body and valve seat are with being threaded; There is liquid outlet on top at valve body, baffle plate is arranged below the liquid outlet, in the centre of baffle plate the fluid center hole is arranged, uniform 6 liquid outlet openings around the fluid center hole; On the valve seat bottom surface, liquid entering hole is arranged.
During use, import and export can repack screw thread into or flange carries out, and are installed in Vertical direction, can prevent that liquid from flowing backwards.Uniform 6 osculums prevent that ball sealer from being stopped up osculum by jack-up in the outlet.
Ball sealer is installed in valve body and the valve seat, is vertically mounted on the pipeline, after liquid enters from lower value seat, back down ball sealer and flow out, when fluid pressure is not enough, drop on the valve seat under the ball sealer, inlet seal is prevented to export liquid flow backwards from outlet.
Four, description of drawings: Fig. 1 is the structural representation of rectilinear one-way valve, among the figure 1, valve body 2, valve seat 3, ball sealer 4, liquid outlet 5, fluid center hole 6, little liquid outlet opening 7, liquid entering hole 8, baffle plate
Five, embodiment: in Fig. 1, the utility model is by valve body 1 and valve seat 2, and ball sealer 3 three parts are formed; Ball sealer 3 is positioned at valve body 1, and is vertically mounted on the liquid entering hole of pipeline; Valve body 1 is threaded with valve seat 2 usefulness; On the top of valve body 1 liquid outlet 4 is arranged, baffle plate 8 is arranged below the liquid outlet 4, fluid center hole 5 is arranged, uniform 6 little liquid outlet openings 6 around the fluid center hole in the centre of baffle plate 8; On valve seat 2 bottom surfaces, liquid entering hole 7 is arranged.
