Abstract
The utility model discloses an automatic sealing water saving valve including a valve seat, a valve body arranged inside a valve seat hole of the valve seat, and an operation rod that is firmly connected with the valve body and drives the valve body to rotate; wherein, the valve body is divided into an upper sealing cover and a lower sealing ring; the upper sealing cover edge is sealed and justified with the lower sealing ring; the lower sealing ring is fixed inside the valve seat; the upper sealing cover is firmly connected with the operation rod; the middle place of the lower sealing ring is provided with an insulation belt that passes through the center and divides the sealing ring into two semicircles; the middle of the upper sealing cover is provided with an insulation piece has the same height of the cover edge and the same length of the insulation belt of the lower sealing ring and divides the sealing cover into two semicircles. The utility effectively solves the problems of disposition, bursting, dropping and leakage that are common in the civil use or industry tube; besides, the utility model has the advantages of safe and economical utilization and long service life.
Description
(1) technical field:
The utility model relates to a kind of water heating fittings, relates in particular to the selfsealings water-saving valve of using on the plumbing pipe
(2) background technique:
At present, the valve that is used on plumbing pipe or the industrial production pipeline is mainly combined by valve seat that is connected with water pipe and the valve body that is positioned at valve seat, its valve body is one cylindric, valve body is connected with screw mandrel, closing and open the lifting by screw mandrel or descending of valve realizes, when valve will be opened, screw mandrel need be mentioned the drive valve body sealing surface and be risen out, and current or its liquid promptly flow into again from the outlet outflow from the import of valve seat.Because valve often need open or close or soak in liquid for a long time under normally open, the screw that screw mandrel and valve seat fasten is worn very soon or becomes rusty decorations and damage, high-pressure water flow or liquid will flow out along screw mandrel between the screw mandrel that is worn and filler slit, and the run, drip, leak of often saying in the industrial production that Here it is show.Cause the waste of water or other liquid, cause irremediable loss to happen occasionally owing to dangerous situation appears in the wearing and tearing of valve in the industrial production.
(3) summary of the invention:
The purpose of this utility model is to solve to be used for the existing problem of run, drip, leak civilian or that industrial pipeline often occurs at present, and the selfsealings water-saving valve of a kind of safety, economy, long service life is provided; The technological scheme of these selfsealings water-saving valve is: a kind of selfsealings water-saving valve, it comprises valve seat, be positioned at the valve body of valve seat shutoff valve seat discharge orifice, the operating handle that the vertical valve body of the drive of fixedlying connected with valve body rotates, its valve body is divided into top cover labyrinth, lower seal two-part, top cover labyrinth lid edge aligns with the lower seal sealing, lower seal is fixed in the valve seat, top cover labyrinth is fixedlyed connected with operating handle, there is an isolation zone by the center that seal ring is divided into two semicircle circles in the middle of the lower seal, have in the middle of the top cover labyrinth one with cover the edge height and equate, with the spacer of lower seal isolation zone equal in length, this spacer is divided equally two semicircle lids with sealing cover.
Be fixed with gland on the operating handle, gland and valve seat are connected as a single entity by screw.
The top is fixed with one handle on the operating handle.
Two groove opposite are arranged on the lower seal edge, and valve seat interior surface has two relative boss, and the groove on the lower seal edge is stuck on the interior boss of valve seat.
Top cover labyrinth has two 90 ° of relative arc boss, and this boss is done 90 ° of rotations by two of valve seat interior surface relative boss restrictions.
(4) description of drawings:
Fig. 1 is a cross-sectional view of the present utility model.
Fig. 2 is the knot plan structure schematic representation of top cover labyrinth.
Fig. 3 is the plan structure schematic representation of lower sealing cover.
Fig. 4 be Fig. 2 along A-A to cross-sectional view.
(5) embodiment:
By Fig. 1-Fig. 4 as can be seen, valve body in the utility model valve seat 7 is divided into top cover labyrinth 4, lower seal 5 two-part, top cover labyrinth 4 lid edge align with lower seal 5 sealings, lower seal 5 is fixed in the valve seat, two groove opposite are arranged on lower seal 5 edges, valve seat 7 internal surfaces have two relative boss, groove on lower seal 5 edges is stuck on the boss in the valve seat 7 it is fixed, top cover labyrinth 4 has two 90 ° of relative arc boss 11, and this boss is done 90 ° of rotations by two of valve seat 7 internal surfaces relative boss restrictions.Also be lined with a rubber pad 6 below the lower seal 4, top cover labyrinth 4 is fixedlyed connected with operating handle 8, there is an isolation zone 9 by the center that seal ring is divided into two semicircle circles in the middle of the lower seal 4, have in the middle of the top cover labyrinth 4 one equate with lid edge height, and the spacer 10 of lower seal isolation zone equal in length, this spacer 10 is divided equally two semicircles with sealing cover 4 and is covered; Be fixed with gland 3 on the operating handle 8, gland 3 and valve seat 7 are connected as a single entity by screw; Operating handle 8 tops are fixed with one handle 2 and are fixed and clamped by nut 1.
In the time of in lower seal is fixed on valve seat, two semicircle circles are relative with water inlet and osculum on the valve seat respectively, at this moment, sealing cover is relative with Mi Quan, isolation zone on the lower seal is relative with the partition of top cover labyrinth, the inner paddle hole of valve seat is separated in two separate cavities, i.e. water-inlet cavity and water chamber, at this moment, valve is in closed condition, when 90 ° of handle with sleeves, spacer intersects with the isolation zone, and two chambeies communicate, this moment, valve was in open mode, medium flows out from the inside of sealing surface, because left rotation and right rotation is just gone up in position in the outer ring of sealing surface, so medium is in sealing state always.No matter open or close, can not cause the lifting or the decline of operating handle, thereby liquid can not occur and from the screw slit, flow out along operating handle, stopped in civilian and the industrial production race, emit, weeping.Top cover labyrinth and lower seal adopt 95 ceramic chips to make, thereby wear-resisting, have guaranteed the longevity of valve.
