Abstract
The utility model discloses novel improvement for a hard sealing gate valve, which comprises a valve body and a gate plate arranged in the valve body. A medium channel is arranged in the valve body, two sealing ring faces are arranged on the medium channel in the valve body, two sealing faces are arranged on the gate plate respectively corresponding to the sealing ring faces, the gate plate moves vertically in the valve body to enable the sealing faces to be connected with or separated from the sealing ring faces and enable the medium channel to be closed or opened, and malposition structures are arranged on the sealing ring faces. The novel improvement is simple in structure, convenient to manufacture and low in cost. After the malposition structures are added, elasticity of connection of the sealing faces and the sealing ring faces is increased, differences of angle matching or surface unfairness between the sealing faces and the sealing ring faces in a processing process are corrected, so that matching of the gate plate and the valve body achieves better sealing effect.
Description
Technical field
The utility model relates to valve, and particularly a kind of novel hard seal gate valve improves.
Background technique
The working principle of gate valve: gate valve is meant the valve that flashboard moves along the Vertical direction of valve rod.Gate valve in pipeline, can only make standard-sized sheet and complete shut-down is intercepted usefulness, can not do to regulate and throttling.Gate valve is as using by medium, and its medium comprises water, oil, and steam makes the handwheel actuate valve stem make flashboard press to valve body sealing surface by force to the transmission of flashboard through certain external power when work, to guarantee the sealing of sealing surface.Flashboard generally is used for the operating mode of standard-sized sheet or full cut-off, is not suitable for as regulating or the throttling use.
Existing a kind of gate valve be through be located at respectively on the flashboard both sides with vertical plane between angle to be small angle such as 3 ° sealing surface and two sealing surfaces in the valve body push to contact by force reaches sealing effect.This type gate valve product the simulation pipeline pressure flow to the Pressure testing state under;, valve wide open supports the air pressure that continues feeding 0.6MPa when ventilating from valve one; Throttle down then, whether have leakage phenomenon, if the sealing pair of flashboard and valve body is zero leakage in 10 minutes from the valve the other end if observing valve; Qualified products then, otherwise be substandard products.And in these existing gate valve products; Often has such defective: because the sealing surface on flashboard and the valve body is on same plane; In the process of processing, deviation and sealing surface out-of-flatness are arranged, in valve complete shut-down process, cause valve leak because of not remedying deviation because of manufacturing tolerance causes the sealing surface angle.
The model utility content
The utility model problem to be solved just provides a kind of novel hard seal gate valve and improves, and is simple in structure, easy to make, with low cost, good sealing effect, the requirements at the higher level of sealability when satisfying high-end customer valve being used.
In order to solve the problems of the technologies described above; The utility model adopts following technological scheme: a kind of novel hard seal gate valve improves; Comprise valve body and be located at the flashboard in the valve body; Be provided with medium channel in the valve body, in valve body, be positioned at be provided with on the medium channel two the sealing anchor rings, flashboard be provided with two sealing surfaces respectively with the sealing anchor ring corresponding one by one; Flashboard moves up and down in valve body and makes sealing surface engage or separate with the sealing anchor ring to make medium channel cut out or open, and it is characterized in that: said sealing anchor ring is provided with misconstruction.
Further, said misconstruction comprises the ring-shaped step that is located on the sealing anchor ring, and the side of ring-shaped step radially slopes inwardly along the sealing anchor ring.
After adopting technique scheme; The utlity model has following advantage: increase the elasticity that sealing surface engages with the sealing anchor ring; Angle in the correction course of working between sealing surface and the sealing anchor ring cooperates the difference that the out-of-flatness phenomenon is arranged with the surface; Reach better sealing effect thereby flashboard is cooperated with valve body, improved the sealability of gate valve greatly, be implemented in the leak free requirement of gate valve in 10 minutes.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is a kind of embodiment's of the utility model a structural representation;
Fig. 2 is the structural representation of valve inner;
Fig. 3 be among Fig. 2 B-B to sectional view.
Embodiment
A kind of embodiment's of the utility model structural representation shown in Fig. 1 to 3; A kind of novel hard seal gate valve improves, and comprises valve body 1 and is located at the flashboard 2 in the valve body, is provided with medium channel 10 in the valve body; In valve body, be positioned at and be provided with two sealing anchor rings 11 on the medium channel; It is corresponding one by one with the sealing anchor ring respectively that flashboard is provided with two sealing surfaces 21, and flashboard moves up and down in valve body and makes sealing surface with sealing anchor ring joint or separate and make medium channel cut out or open, and said sealing anchor ring is provided with misconstruction; Said misconstruction comprises the ring-shaped step 12 that is located on the sealing anchor ring, and the side of ring-shaped step radially slopes inwardly along the sealing anchor ring.The size of ring-shaped step is less, and for performance structure has adopted the exaggerative technique of painting, in this enforcement, ring-shaped step is provided with one, and two or more can certainly be set in Figure of description.
