Abstract
The utility model relates to a maintainable cold water valve, belonging to the water heating pipe fitting manufacturing technical field. The maintainable cold water valve comprises a valve body, a valve core, and a valve stem and a handle connected with the valve core. The cavity of the valve body is divided into a water inlet chamber and a water outlet chamber by a separation wall, wherein, the water inlet chamber and the water outlet chamber are respectively provided with a water inlet and a water outlet; the separation wall is provided with a water hole; a sealing gasket covers the orifice of the water hole at one side of the water outlet chamber to seal the water hole; the valve core withstands the sealing gasket vertically. In use, the water inlet of the valve body is connected with the water supply pipeline; as the handle is rotated to make the valve core withstand the sealing gasket tightly, the sealing gasket seals the water hole of the valve body cavity, the water in the water inlet chamber is prevented from entering the water outlet chamber, and the valve is in an off state; as the handle is rotated to turn on the valve, the sealing gasket is detached from the separation wall in the cavity with the function of the water pressure, the water in the water inlet chamber enters the water outlet chamber through the water hole and is exhausted through the water outlet. The maintainable cold water valve has the advantages of simple structure, convenient operation, easy maintenance, low cost, long service life and resource saving.
Description
Technical field
The utility model relates to a kind of pipe member, and particularly a kind of cold valves of safeguarding belongs to hot-water heating pipe fitting production technical field.
Background technique
In the prior art, the cold valves kind is a lot, divide but cut logical principle from current, nothing more than two kinds: a kind of be parallel section logical, another kind be vertical cut logical.So-called parallel section logical being meant, when water valve by the time, water is in the rear end of valve, when water valve is opened, water by after the parallel forward valve that passes; So-called vertical logical being meant of cutting, when water valve ended, water was in the lower end of valve, and when water valve was opened, water passed valve from bottom to top.The principle that vertical section water-through valve intercepts water is that valve rod drives the zero-clearance coupling between spool and the body cavity water port, in other words is exactly sealing.The valve seal of parallel section logical class realizes by metallic material often, and the valve seal major part of vertically cutting logical class realizes by rubber material, and it is by the metallic material realization that part is also arranged.These cold valves all are disposable products basically, if leaked, can only more renew, and the water valve of pulling down is thrown away.Especially vertical section logical class water valve is very short working life, and this has caused the waste of resource undoubtedly.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of simple in structure, and the cold valves of being convenient to safeguard to prolong the working life of cold valves, cuts the waste.
The technical scheme in the invention for solving the technical problem is as follows: a kind of cold valves of safeguarding, comprise valve body, spool in the structure, valve rod that links to each other with spool and handle, be characterized in that body cavity is divided into intake chamber and water-supplying chamber by partition wall, intake chamber and water-supplying chamber are respectively equipped with water intake and water outlet, have the water port that communicates with intake chamber and water-supplying chamber on the partition wall, be stamped diameter greater than the water port diameter and make the seal washer of this water port sealing on the aperture, water port of water-supplying chamber's one side, spool is positioned at water-supplying chamber and replaces on seal washer.
The cold valves of safeguarding of the present utility model belongs to vertical cut logical class water valve, seal washer and spool split, make the water port realize sealing by seal washer,, can in time change in case seal washer leaks, can normally use, thereby realize prolonging the cold valves purpose in working life.
The said cold valves of safeguarding is characterized in that the partition wall of body cavity is made up of two sections perpendicular partition walls and one section horizontal partition wall, and open on horizontal partition wall the water port, and spool is vertically replaced on seal washer.
For the facility on processing, the described cold valves of safeguarding, seal washer uses rubber material, is generally circle, is provided with through hole therebetween.The purpose of perforate be prevention under the situation that valve is closed for a long time, rubber gasket and water port metal o-ring be bonding cause can not water flowing the situation appearance.
Using method of the present utility model is: during use, the water intake of valve body is linked to each other with supply channel, water enters intake chamber, and the valve body water outlet becomes the nature water outlet.Handle with sleeve is with spool top tight sealing packing ring, and then seal washer makes the water flowing aperture sealing of body cavity and blocks, and the water in the intake chamber can't enter water-supplying chamber by the water port, and valve is in closed condition; When needs were opened, only need backward rotation handle lifted spool and breaks away from seal washer, and seal washer breaks away from the chamber internal partition wall under hydraulic action, and the water in the intake chamber enters water-supplying chamber by the water port, discharges through water outlet.
The beneficial effect that the utility model is obtained is: this cold valves is simple in structure, and is easy to operate, is easy to safeguard that cost is low, and prolong working life, economizes on resources.
Description of drawings
Accompanying drawing 1 is a partial sectional view of the present utility model.
The implication of each label representative is as follows among the figure:
