Description
The utility model relates to valve technology field, is a kind of delayed self-close water-saving valve.
Existing valve kind is a lot, and as water halter, self-closing valve, and general self-closing valve mechanism complexity, poor reliability, working life are short, after using a period of time, just be prone to leakage phenomenon, even damage and can not use, thereby wasted precious water resource.
In view of the problem that prior art exists, the purpose of this utility model is to design a kind of simple in structure, delayed self-close water-saving valve that reliability is high.The purpose of this utility model also is to design a kind of delayed self-close water-saving valve of long service life of good airproof performance.
The purpose of this utility model realizes by following measure: water intake and water outlet are arranged on the valve body of this delayed self-close water-saving valve, cylinder body is fixedly mounted in the valve body by sealing seat, and piston is housed in the cylinder body, form water-inlet cavity between cylinder body and the valve body, form vacuum chamber between piston and the valve body, form water-injecting cavity between piston and valve body and the sealing seat, form water cavity between sealing seat and the valve body, water intake communicates with water-inlet cavity, water inlet with water-inlet cavity and water-injecting cavity UNICOM is arranged on cylinder body, water port with water-injecting cavity and water chamber UNICOM is arranged on sealing seat, water chamber communicates with water outlet, can be fixedly mounted on the piston by axially movable push rod one end, be interlinked to the outside spring is being installed between piston and the cylinder body or between push rod and the valve body and the other end passes water port and valve body, the sealing surface that can seal the water port is arranged on the push rod; Sealing surface is that the conical surface on the push rod constitutes; Sealing surface is that the seal ring sphere on the push rod constitutes; Sealing surface is that plane or the conical surface seal pad on the push rod constitutes; Piston packing is being arranged on the piston or on the push rod; Push rod is installed on the valve body by valve gap; Between push rod and valve gap, spring is installed; Between push rod and valve body or valve gap, seal ring is installed; Sealing surface, piston and cylinder body form concentric structure; Between sealing seat and cylinder body, sealing gasket is arranged.
Accompanying drawing is that the master of the utility model most preferred embodiment looks the sectional structure schematic representation,
Coding in the accompanying drawing is respectively: 1 is valve body, and 2 is cylinder body, and 3 is piston packing, and 4 is piston, and 5 is seal ring, and 6 is sealing gasket, and 7 is sealing seat, and 8 is valve gap, and 9 is spring, and 10 is seal ring, and 11 is push rod; A is a water-inlet cavity, and B is a vacuum chamber, and C is a water-injecting cavity, and D is the water inlet, and E is a water chamber.
Below in conjunction with most preferred embodiment and accompanying drawing the utility model is further described:
As shown in drawings, on the valve body 1 of this delayed self-close water-saving valve water intake and water outlet are arranged, cylinder body 2 is fixedly mounted in the valve body 1 by sealing seat 7, and piston 4 is housed in the cylinder body 2, form water-inlet cavity A between cylinder body 2 and the valve body 1, form vacuum chamber B between piston 4 and the valve body 1, form water-injecting cavity C between piston 4 and valve body 1 and the sealing seat 7, form water cavity E between sealing seat 7 and the valve body 1, water intake communicates with water-inlet cavity A, water inlet D with water-inlet cavity A and water-injecting cavity C UNICOM is arranged on cylinder body 2, water port with water-injecting cavity C and water chamber E UNICOM is arranged on sealing seat 7, water chamber E communicates with water outlet, can be fixedly mounted on the piston by axially movable push rod 11 1 ends, and the other end passes the water port and valve body is interlinked to the outside, and between piston 4 and the cylinder body 2 or between push rod 11 and the valve body 1 spring 9 is being installed, and the sealing surface that can seal the water port is arranged on the push rod 11.During work: at first promote push rod 11, make sealing surface on the push rod 11 leave water port on the sealing seat 7, thereby make water flow into water-injecting cavity C, flow into water chamber E and flow out from water outlet and flow into the water port of water on sealing seat 7 in the water-injecting cavity C through water intake, water-inlet cavity A and water inlet D; When promoting push rod 11, piston 4 interlocks also make the water in the vacuum chamber B enter water-injecting cavity C along the gap between piston 4 and the cylinder body 2; After unclamping push rod 11, under the difference effect of the vacuum pressure of the elastic force of spring 9 and vacuum chamber B, push rod 11 resets gradually, until the sealing surface on the push rod 11 water port on the sealing seat 7 is sealed up, and is about to water-injecting cavity C and blocks with water chamber E, thereby current are stopped.
In order to reach the better seal effect, according to different situations, the conical surface that sealing surface can be on the push rod constitutes, perhaps sealing surface also can be the seal ring formation on the push rod, perhaps sealing surface is plane or the conical surface seal pad formation on the push rod, the seal ring that sealing surface is preferably on the push rod constitutes, as shown in drawings.
As shown in drawings, for the ease of installing, push rod 11 is installed on the valve body 1 by valve gap 8, and spring is installed between push rod 11 and the valve gap 8.
For further anti-sealing spills from push rod 11, between push rod 11 and valve body 1 or valve gap 8, seal ring is installed, valve gap is arranged, be preferably between push rod 11 and the valve gap 8 seal ring 10 is installed, as shown in drawings.
As shown in drawings, between sealing seat 7 and cylinder body 2, sealing gasket 6 is arranged preferably, leak to prevent water; As shown in drawings, sealing surface is that seal ring 5, piston 4 form concentric structure with cylinder body 2.
The utility model is simple in structure, reliability is high, easy for installation, good seal performance, long service life, utilizes this delayed self-close water-saving valve, has good water-saving result, and safety and sanitary are easy to use, are particularly suitable for family or public place.
