Problems solved by technology

[0004] 1. Because the traditional silicone pad is used, and the silicone is soft, and the silicone used in the traditional valve core is relatively thick. Although the silicone pad is installed, under high pressure, it is easy to cause the product to leak due to the deformation of the silicone , especially in the case of reverse water inflow, this situation is more likely to occur and is much more serious, so the pressure resistance of the traditional spool is very limited
[0005] 2. The traditional quick-opening valve core generally has two grooves on the valve stem, which are sealed with an O-ring, so that the valve stem below the sealing ring is soaked in water for a long time during use. On the one hand, the valve stem It is easy to be oxidized and affects the service life. On the other hand, when metal is soaked in water, it is easy to make heavy metal precipitates into the water, causing secondary pollution to drinking water, and causing adverse effects on people's health and the development of infants and young children.
[0006] 3. The valve stem used by the traditional quick-opening valve core is designed with two forks for positioning and switching water. These two forks are very difficult to process for metal materials with high hardness, and the processing cost is very high. As a result, the cost of the entire product is high and it is difficult to promote
[0008] At present, due to the relatively few application scenarios, the difficulty of obtaining accurate information will cause many uncertain factors and many other problems, the existing relevant research is relatively lacking.

Embodiment Construction

[0029] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0030] Such as Figure 1-7 As shown, the high-pressure resistant quick-opening valve core of the split type ceramic seal realized by the present invention includes a valve stem 1, a valve stem lubricating gasket 2, a valve core main body pressure cap 3, a ceramic moving plate O-shaped sealing ring 4, a pressure Cap O-shaped sealing ring 5, ceramic moving plate 6, spool body cover 7, anti-skid and anti-off silicone sleeve 8, ceramic static plate 9 and, silicone sealing ring 10.

[0031] combine figure 2 , image 3 , Figure 4 As shown, in order to solve the defect that the silica gel is deforme...

Abstract

The invention discloses a split type ceramic sealed high-pressure-resistant quick-opening valve element. The high-pressure-resistant quick-opening valve element comprises a valve rod, a valve element body sleeve, a ceramic movable sheet and a ceramic static sheet, a sealing groove is formed in the lower portion of the ceramic static sheet, and a silica gel sealing ring is embedded in the sealing groove; and meanwhile, the periphery of the ceramic static sheet is provided with an anti-skid and anti-disengagement groove, an anti-skid and anti-disengagement silica gel sleeve is arranged in the anti-skid and anti-disengagement groove, and the anti-skid and anti-disengagement silica gel sleeve can block the ceramic static sheet so that the ceramic static sheet can not disengage from the valve element body sleeve. According to the split type ceramic sealed high-pressure-resistant quick-opening valve element, the four defects of a traditional valve element are completely overcome, the product machining cost is lower, the product grade and quality are higher, and the valve element is healthier and more environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of valves, and more specifically relates to a high-pressure-resistant quick-opening valve core with a split-type valve stem that is directly sealed by water-proof ceramics. Background technique [0002] The existing quick-opening valve core mainly consists of a valve stem, a valve core main body, a ceramic moving piece, a ceramic static piece, a valve stem lubricating gasket, a valve stem O-ring, a main body O-ring, a sealing silica gel pad, a silica gel Pad composition. [0003] There are many disadvantages of this spool: [0004] 1. Because the traditional silicone pad is used, and the silicone is soft, and the silicone used in the traditional valve core is relatively thick. Although the silicone pad is installed, under high pressure, it is easy to cause the product to leak due to the deformation of the silicone , especially in the case of reverse water inflow, this situation is more likely to occur and ...
