Description

Explosion-proof environment-friendly quick-opening faucet sealed by all ceramics without independent valve core
Technical Field
The invention relates to the technical field of quick-opening faucets, in particular to an explosion-proof environment-friendly quick-opening faucet which is sealed by full ceramics and has no independent valve core.
Background
Most of the prior quick-opening faucets are provided with independent valve cores, namely a handle, a quick-opening faucet main body and the quick-opening valve cores are composed of three main parts, and a small part of the prior quick-opening faucet has a design scheme without the independent valve cores, but the prior quick-opening faucet is difficult to process in the design of a valve rod, or the processing cost is higher, or water leaks due to metal oxidation. In the traditional quick-opening faucet, because an independent valve core is used, the sealing is mainly realized by a thick silica gel pad, and the silica gel pad is thicker, so that the traditional quick-opening faucet is easy to deform under the condition of higher pressure to cause water leakage, and particularly when the traditional quick-opening faucet is used in a reverse direction, the probability of water leakage is higher; thirdly, most importantly, the conventional quick-opening faucet is mainly provided with a copper quick-opening independent valve core, and the copper valve core contains heavy metal lead far exceeding the national standard, so that secondary pollution is caused to water, the physical health of people is seriously influenced by direct drinking, and particularly, the influence on the intelligence development of children in the infant stage is huge. The product of the invention is designed better and more scientifically aiming at the problems.
Disclosure of Invention
Aiming at the problems, the invention provides an explosion-proof environment-friendly quick-opening faucet which is sealed by full ceramics and has no independent valve core.
In order to solve the technical problems, the technical scheme provided by the invention is as follows: the utility model provides a totally ceramic seal's of no independent case explosion-proof environmental protection is tap soon opened, it includes and opens tap body, hand wheel soon, takes the cup to press cap, valve rod, pottery moving plate and pottery still, pottery still and pottery moving plate from the bottom up install respectively inside the tap body soon opens, it is the helicitic texture soon to open tap body upper end inside, take cup to press cap lower extreme cooperation screw in to open tap body upper end soon, the valve rod pegs graft in taking the cup to press the cap, the valve rod upper end is passed and is taken cup to press cap and lateral wall to be spline structure, the hand wheel cooperation is pegged graft in the valve rod upper end, the valve rod lower extreme is pegged graft in pottery moving plate upper end.
As an improvement, the two sides in the quick-opening faucet body are respectively provided with a stator positioning lug, and the two sides of the ceramic stator are provided with positioning grooves matched with the stator positioning lugs.
As an improvement, two side walls below the ceramic moving piece are respectively provided with a limiting block matched with the stator positioning lug, and the upper end of the ceramic moving piece is provided with a sealing groove along the circumferential direction.
As an improvement, the valve rod comprises a convex block or a groove which is positioned at the bottom, and a slot or an insertion block which is matched with the convex block or the groove is arranged above the ceramic moving plate.
As an improvement, an O-shaped sealing ring of the pressing cap is arranged above the joint of the pressing cap with the cup and the quick-opening tap body.
As an improvement, a ceramic moving plate O-shaped sealing ring is arranged in the sealing groove.
As an improvement, a silica gel sealing gasket is arranged in the quick-opening faucet body below the ceramic stator plate.
After adopting the structure, the invention has the following advantages: 1. a, the material selection range of the valve core is increased, the traditional valve core is preferably made of a copper material, the copper material is easy to process and difficult to oxidize, but the defect of the copper material is obvious, the lead content is high, the valve core is easy to break, after the valve core is changed into a valve core without an independent valve core, the gland and the valve rod are designed into the simplest and easiest structure, so that a 304 or 316 stainless steel material which is difficult to process is replaced, a high-quality product can be finished at low production cost, and meanwhile, the stainless steel material is not easy to break and does not contain lead! Therefore, the stainless steel can be used as an environment-friendly stainless steel product, is free of lead and fracture, and is low in production cost.
B. The product without the independent valve core mainly omits a porcelain bushing below the valve core main body, so the material is saved.
2. Adopts a full ceramic structure, is the most environment-friendly and healthier material because the ceramic is high temperature resistant, acid resistant, alkali resistant and corrosion resistant, and in the using process, the water can not be secondarily polluted, and harmful substances such as heavy metal generation and the like are completely avoided, thereby being more beneficial to the health!
3. The sealing adopts the thin and high food-grade silica gel pad and the rubber ring of hardness, and the rubber ring dress is in the seal groove of pottery moving plate, through detecting, can normal use under 30kg pressure, than the structure that the independent case of tradition is sealed with ordinary silica gel, high pressure resistant more.
4. The design of the quick-opening main body increases two symmetrical still positioning lugs on the inner wall, and not only increases the strength of the main body except the functions of the main body, but also ensures that the main body is more explosion-proof!
5. The design and use of the gland with the cup are simpler when a split handle (hand wheel) is installed, the cost is lower, the produced grade is higher, and the gland is more easily accepted by consumers.
