Abstract

The invention discloses a push-type water-saving valve, comprising a valve body, a valve rod, a piston and a connecting rod, wherein the valve rod comprises a cylinder barrel with an upper opening anda guide rod; the guide rod is matched with a valve rod seat in the valve body and in an installation channel in a sliding manner; the piston is matched with the cylinder barrel; a cylinder cover is matched with the cylinder barrel in a dismountable manner; a spring is arranged between the cylinder cover and the piston; the push-type water-saving valve is characterized in that butter oil is infused in the cylinder barrel; an oil storing chamber is arranged on the piston, a steel ball is arranged in the oil storing chamber. By adopting the structure, the distance that valve rod moves down can be used for regulating the distance of the valve core and the valve core seat, thus achieving the purpose of regulating the water quantity; the valve rod loses pressure, and the valve core is restoredand matched with the valve core seat under the action of the spring; the valve core is tightly combined with the valve core seat due to the action of the spring, which can effectively prevent water from leaking; oil slowly enters the cylinder barrel through an oil guide groove on the wall of the piston under the action of negative pressure; finally the water gap is closed by ascending of the connecting rod when pressure is balanced, which plays a role of timelag.

Description

A kind of push-type water-saving valve

Technical field

The present invention relates to a kind of water valve.

Background technique

In the prior art, a kind of push-type water-saving valve comprises main body, valve body, valve rod, spool, opens handle, and valve body is installed on the main body, and intake pipe, water outlet are arranged on the main body; Valve body has valve rod passage, osculum, water inlet is installed; Spool cooperates with the valve core case of valve body, and described valve rod is made of cylinder barrel, the guide rod of upper shed, and guide rod is slidingly matched with the valve rod base of installing in the passage, and guide rod and spool are fixedly connected; Also comprise a piston, connecting rod, piston cooperates with cylinder barrel, and a cylinder cap detachably cooperates with cylinder barrel, is provided with spring between cylinder cap and the piston, and connecting rod and cylinder cap are slidingly matched, the valve gap scyewed joint of connecting rod and valve body upper end; The directional post of opening handle inserts in the pilot hole of valve gap and is slidingly matched, and directional post cooperates with cylinder cap; Press lower handle, handle promotes piston, descending in piston cylinder, the air of extruding in the cylinder barrel, when lifting hand, return spring pulling piston return, because the effect of piston rubber sealing, make and produce negative pressure in the piston cylinder, shortcoming: since with air as the time-delay medium, can not reach this type of technical products time-delay of national regulation 4--6 second, the fashion of dispatching from the factory can be used, the general time just be difficult to later guarantee stable cause defective.

Summary of the invention

The objective of the invention is: a kind of push-type water-saving valve is provided, and its can regulate streamflow according to pressing down the distance of the handle of fetching boiling water, and the spool time-delay cooperates with valve core case, can prevent from effectively to leak.

The present invention is achieved in that a kind of push-type water-saving valve, comprises valve body, valve rod, piston and connecting rod, and described valve rod is made of cylinder barrel, the guide rod of upper shed, and valve rod base in guide rod and the valve body, that install in the passage is slidingly matched; Piston cooperates with cylinder barrel, and a cylinder cap detachably cooperates with cylinder barrel, is provided with spring between cylinder cap and the piston, and connecting rod and cylinder cap are slidingly matched, the valve gap scyewed joint of connecting rod and valve body upper end; Its special way is: be marked with buffering oil in the cylinder barrel; Piston is provided with shoe cream room, is provided with steel ball in the shoe cream room; Oil guide slot is arranged on the piston wall.

Described a kind of push-type water-saving valve, its special way is: described shoe cream room is the class convex shape; The bottom of shoe cream room is that buffer cavity, top are the steel ball chamber.

A kind of push-type water-saving valve of the present invention, owing to adopt such structure, the distance that valve rod moves down can regulating spool and the distance of valve core case, thereby reaches the purpose of regulating water-quantity; Valve rod loses pressure, and under the effect of spring, valve core reset cooperates with valve core case, because the effect of spring, spool combines with valve core case closely, can prevent from effectively to leak; The oil guide slot of oil on piston wall slowly enters in the cylinder barrel under suction function, reaches pressure balance at last and the up mouth of a river of closing of connecting rod, plays time-lag action.

Embodiment

Below in conjunction with accompanying drawing the present invention is further described.

As shown in Figure 1 and Figure 2, a kind of push-type water-saving valve comprises main body 1, valve body 2, valve rod 5, spool 3, opens handle 4, and valve body 2 is installed on the main body 1, and intake pipe 11, water outlet 12 are arranged on the main body 1; Valve body 2 has valve rod and passage 22, osculum 23 is installed, is positioned at the water inlet on the valve core case 21; Spool 3 cooperates with the valve core case 21 of valve body 2, and described valve rod 5 is made of cylinder barrel 51, the guide rod 52 of upper shed, and guide rod 52 is slidingly matched with the valve rod base of installing in the passage 22 221, and guide rod 52 is fixedly connected with spool 3;

Osculum 23 is on the valve body 2 between valve rod base 221, the valve core case 21.

Also comprise a piston 6, connecting rod 7, piston 6 cooperates with cylinder barrel 51, and a cylinder cap 8 detachably cooperates with cylinder barrel 51, is provided with spring 9 between cylinder cap 8 and the piston 6, and connecting rod 7 is slidingly matched with cylinder cap 8, valve gap 10 scyewed joint of connecting rod 7 and valve body 8 upper ends; The directional post of opening handle 4 inserts in the pilot hole of valve gap 10 and is slidingly matched, and directional post cooperates with cylinder cap 8.

Piston 6 is provided with shoe cream room 61, is provided with steel ball 62 in the shoe cream room 61; Be marked with buffering oil in the cylinder barrel 51; On piston 6 walls oil guide slot is arranged.

Described shoe cream room 61 is the class convex shape; The bottom of shoe cream room 61 is that buffer cavity, top are the steel ball chamber.

The present invention in use, down by opening handle 4, cylinder cap 8, valve rod 5 move down, spool 3 leaves valve core case 21, then water is by there being intake pipe 11 on the main body 1, the water inlet on the valve core case 21, osculum 23 enters the water outlet 12 of main body 1, flows out water.

Open handle 4 and lose pressure, under the effect of spring 9, cylinder cap 8, valve rod 5 are returned to original position, and spool 3 cooperates with valve core case 21, the water inlet of cut-off valve core print seat 21.The effect of spring 9 makes spool 3 and water inlet close fit, prevents to leak.
