Abstract
The utility model relates to a ceramic core valve which comprises a valve body 1, a valve core 2, a handle 3, a headstock gear, etc., wherein the valve core 2 comprises a movable ceramic blade 21 and a fixed ceramic blade 22 which are provided with through holes at corresponding locations, and the valve core 2 is directly arranged in the limiting cavity of the water control channel of the valve body 1. The headstock gear is formed by the vertical running fit of the movable blade 21 of the valve core 2 and a deflector rod 4 fixedly connected with the handle 3. The fixed blade 22 uses ceramic material, and the contact face with the movable ceramic blade is very smooth. The opening gear of the fixed blade 22 belongs to rotation engaging, and the opening is easy. Because of the corrosion resistance and the abrasion resistance of the fixed ceramic blade and the function of a sealing rubber ring tightly fitted with the fixed blade, the fixed ceramic blade can still keep sealing match, and the service life is extended.
Description
The utility model relates to a kind of valve, and is particularly relevant with a kind of valve of ceramic core.
The valve of commonly using as shown in Figure 1, comprise parts such as valve body 1, spool 2, handle 3 and start-stop device, described spool is for directly being arranged on the spheroid of the middle part through hole in the limit chamber of control water channel of valve body 1 by the O-ring seal sealing, it directly stretches out a body of rod and handle 3 is affixed, the through hole that rotation by handle 3 makes spheroid communicates with the control water channel or seals in out of phase, and its main shortcoming of the valve of said structure is:
1, be O-ring seal because of what match with sphere, therefore, this valve opening is effort.
2, because metal ball body contacts with water for a long time, therefore, if time length is not opened, then this valve easily gets rusty and stops up, and reduces its working life.
3, because the wearing and tearing of the perishable and metal ball body of caulking gum when cooperating, after service time was long, this valve closing was not tight, also influences its working life.
At above-mentioned defective, the purpose of this utility model is to provide a kind of valve of ceramic core, and it is easy to use, and the life-span is longer.
For reaching above-mentioned purpose, solution of the present utility model is: a kind of ceramic core valve, comprise parts such as valve body 1, spool 2, handle 3 and start-stop device, described spool 2 comprises that corresponding position is provided with the moving vane sheet 21 of fan-shaped pylone and decides limb 22, it is set directly in the limit chamber of control water channel of valve body 1, described start-stop device by the moving vane sheet 21 of spool 2 with and the affixed driving lever 4 of handle 3 be rotatably assorted and form.
Described spool 2 can be by the ceramic moving vane sheet 21 in the sleeve pipe 23 and the sleeve pipe 23 of packing into successively, pottery is decided limb 22 and O-ring seal 24 is formed, through hole and ceramic moving vane sheet 21 that driving lever 4 passes on the sleeve pipe 23 are rotatably assorted, and make this moving vane sheet 21 of pottery and the ceramic through hole of deciding limb 22 communicate or seal in out of phase.
Described start-stop device also can be formed by the gear teeth meshing that forms on the driving lever 4 terminal gear teeth that form and the ceramic moving vane sheet 21.
Described pottery is decided corresponding projection and the groove of being provided with sleeve pipe 23 cooperation positions of limb 22, and its order pottery is decided not rotatable being positioned in the sleeve pipe 23 of limb 22.
After adopting said structure, the utility model adopts ceramic materials because pottery decide limb 22, and its surface of contact with ceramic moving vane sheet is more smooth, and its opening device is engagement in rotation, and therefore, unlatching is easy.In addition, because pottery is fixed, the corrosion resistance and the wearability of moving vane sheet, this life of valve is prolonged, even and limb decided by pottery and moving vane sheet phase-contact surface has wearing and tearing, because of deciding the effect of the O-ring seal that limb is close to pottery, also can make pottery decide limb and be close on the ceramic moving vane sheet, keep being sealed and matched.
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is a plan cross-section schematic representation of commonly using product of the present utility model;
Fig. 2 is a plan cross-section schematic representation of the present utility model;
Fig. 3 is an operating state schematic representation of the present utility model.
See also Fig. 2, shown in Figure 3, a kind of preferred forms that provides for the utility model, its structure is: the ceramic core valve, comprise valve body 1, spool 2, parts such as handle 3 and start-stop device, described spool 2 comprises that corresponding position is provided with through hole 211,221 ceramic moving vane sheet 21 and pottery are decided limb 22, this spool 2 is set directly in the limit chamber 11 of control water channel of valve body 1, described start-stop device by the ceramic moving vane sheet 21 of spool 2 with and affixed driving lever 4 vertical rotation of handle 3 cooperates and forms, the gear teeth 212 Vertical Meshing that form on the gear teeth 41 that its structure can be formed by driving lever 4 ends and the ceramic moving vane sheet 21 form.
Described spool 2 can be by the ceramic moving vane sheet 21 in the sleeve pipe 23 and the sleeve pipe 23 of packing into successively, decide limb 22 and O-ring seal 24 is formed, the through hole 231 that driving lever 4 passes on the sleeve pipe 23 is rotatably assorted with ceramic moving vane sheet 21, makes this pottery moving vane sheet 21 and the ceramic through hole 211,221 of deciding limb 22 communicate or seal in out of phase.
Described pottery is decided corresponding projection 223 and the groove 232 of being provided with sleeve pipe 23 cooperation positions of limb 22, and its order pottery is decided not rotatable being positioned in the sleeve pipe 23 of limb 22.
When above-mentioned ceramic core valve is interfered in no external force, be in normally off, as shown in Figure 2, at this moment, through hole 211 on the pottery moving vane sheet 21 is in the not communicating state that staggers mutually with the through hole 221 that pottery is decided on the limb 22, at this moment, because pottery is decided the effect of limb 22 and O-ring seal 24, water can not flowed out from the outlet port by spool 2, and when pull handle 3 with hand, this handle 3 drives driving lever 4 and rotates, because the end of driving lever 4 forms the gear teeth 41, the gear teeth 212 Vertical Meshing that form on itself and the ceramic moving vane sheet 21, then ceramic moving vane sheet 21 rotates under the drive of the gear teeth 41, thereby the through hole 211 on the ceramic moving vane sheet 21 is communicated with the ceramic through hole of deciding on the limb 22 221, at this moment, the ceramic core valve is in opening state, and intake tunnel communicates with exhalant canal, and current can flow out from water outlet, it must be closed again, need only handle with sleeve 3, the through hole 211 of moving vane sheet 21 is staggered mutually with the through hole 221 that pottery is decided limb 22, this valve is in sealing state.
The foregoing description only is a kind of mode of execution of the present utility model; in use; the utility model also can adopt other similar structure; start-stop device as this ceramic core valve can not adopt the gear engagement form; can adopt the plectrum on the driving lever to cooperate with plectrum on the ceramic moving vane sheet; stirring ceramic moving vane sheet rotates in several angle; also can reach the purpose of this utility model; as long as its structure satisfies ceramic moving vane sheet and the pottery that spool comprises that corresponding position is provided with through hole and decides limb; it is set directly in the limit chamber of control water channel of valve body; described start-stop device by the ceramic moving vane sheet of spool with and the affixed driving lever vertical rotation of handle cooperates and forms, be the scope that the utility model is protected.
