Description

Stop valve

Technical Field

The utility model relates to the technical field of valves, in particular to a stop valve.

Background

The stop valve is a valve body arranged at the water outlet and can control water outlet;

conventional shut-off valves: the sealing device consists of a ring piece, a threaded rod, a sealing block and a sealing plug, wherein the sealing plug and the ring piece are matched to seal a pipeline, and the threaded rod can drive the sealing block and the sealing plug to move up and down when rotating;

the above-mentioned shut-off valve has the disadvantage: because the sealing plug is the rubber material, and the sealing plug is direct with the contact of ring spare, receive the impact of rivers for a long time, some impurity in the water can adsorb on the sealing plug surface, because the sealing plug of rubber material can receive the influence of impurity to take place deformation again, influences the sealed effect of sealing plug, appears the phenomenon that tap drips.

Therefore, a shut-off valve capable of solving the above-mentioned problems is demanded.

Detailed Description

In order that the above objects, features and advantages of the utility model will be more clearly understood, a further description of the utility model will be rendered by reference to the appended drawings and examples. It should be noted that, in the case of no conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model, however, the present utility model may be practiced otherwise than as described herein, and therefore the present utility model is not limited to the specific embodiments of the disclosure that follow.

As shown in fig. 1 and 2, in the embodiment of the present utility model: the utility model provides a stop valve, including disk seat 110, inlet 120 has been seted up to disk seat 110 below, and outlet 130 has been seted up in disk seat 110 left side, rivers flow through outlet 130 after flowing in by inlet 120, inlet 120 inner wall connection has ring 210, and ring 210 has seted up the apopore, rivers can go out water through the apopore, and shutoff apopore can accomplish the rivers and stop, disk seat 110 top threaded connection has threaded rod 220, threaded rod 220 can reciprocate when the pivoted, and threaded rod 220 top is connected with the twist grip 230, the more convenient rotation threaded rod 220 of workman, threaded rod 220 below is connected with sealed head 240, and sealed head 240 below is connected with sealed 250, ring 210 upper surface is provided with scraper 260, and scraper 260 right-hand member is connected in ring 210 upper surface through the pivot.

In a specific operation, a worker rotates the rotary handle 230 to drive the threaded rod 220 and the sealing head 240 to rotate, and the sealing head 240 and the sealing pad 250 can be driven to move upwards under the action of the threaded rod 220 and the threaded connection of the valve seat 110, at this time, the water flow impact scraper 260 drives the rotary handle to rotate, the left end of the scraper 260 abuts against the sealing pad 250, and as the sealing pad 250 continuously ascends, the scraper 260 abuts against the surface of the sealing pad 250 to rotate clockwise, so that impurities on the surface of the sealing pad 250 are scraped, and when the sealing head 240 and the sealing pad 250 descend, the scraper 260 is extruded by the sealing pad 250 to rotate anticlockwise along the lower surface of the sealing head 240 and the sealing pad 250, and impurities on the surface of the sealing pad 250 are scraped again.
