Description
Technical field
The utility model relates to valve processing technique field more particularly to a kind of angle valves with non-return structure.
Background technique
In existing technology, for the valve of fluid control systems, from simplest shut-off valve to it is extremely complex from
Various valves used in control system, kind and specification are quite various, and valve can be used for controlling empty gas and water, steam, various corruption
The flowing of the various types fluid such as corrosion medium, mud, oil product, liquid metal and radiating medium, currently in order to improving to horse
Bucket control intake pressure and the function of closing water inlet install angle valve in closestool water inlet, and angle valve is angle stop valves, angle valve sheet
Body includes shell and spool, and spool is connected with external handle, and angle valve ontology upper end is equipped with blasthole, blasthole and water supplying pipe
Road is connected, and one end is equipped with apopore, and apopore is connected with toilet tube, and the blasthole and apopore of angle valve are straight at 90 degree
Angle, the most important use of angle valve be exactly hydraulic pressure is unstable or the condition of hydraulic pressure super large, installation angle valve prevent the water in closestool by
Lead to explosion failure in hydraulic pressure is excessive, repairs and replace in the future hose and also to convenient, but when cutting off the water or hydraulic pressure hair
When raw larger fluctuation, the moment of valve or tap is opened after resuming water supply again, can make to generate in water supply line instantaneous negative
Pressure, causes the water in closestool to flow back.
Utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and providing one kind can keep away
Exempt from the angle valve with non-return structure of pipeline water reflux.
The utility model is to be achieved by the following technical programs:
A kind of angle valve with non-return structure, which is characterized in that including angle valve ontology, the handle being connect with angle valve ontology,
Interconnecting piece and time locking mechanism, the angle valve ontology and interconnecting piece are affixed, and angle valve ontology upper side is provided with blasthole, the blasthole
Top is connected with back locking mechanism, and described time locking mechanism includes hollow cavity, interior concave ring, baffle, spring and supporting rib, the chamber
Body lower end is connected with supporting rib, and the supporting rib upper surface is connected with guide rod, and guide rod channel, the guide rod are provided on the baffle
Upper end passes through guide rod channel, and guide rod outside disc is equipped with spring, and the both ends of the spring and baffle and supporting rib are affixed, in the cavity
Interior concave ring is equipped in the middle part of side, the interior concave ring downside is provided with annular groove, is connected with sealing ring inside the annular groove,
The spring resists baffle, fits closely baffle with the sealing ring lower surface in annular groove.
The beneficial effects of the utility model are:
Due to being connected with back locking mechanism above blasthole, when angle valve is opened, the water flow in water supply line is downward to baffle
Active force be greater than the spring active force upward to baffle, open non-return mechanism, water supply line gives closestool to supply water, when cutting off the water or
When larger fluctuation occurs for person's hydraulic pressure, the moment of valve or tap is opened after resuming water supply again, can make to produce in water supply line
Raw instantaneous negative pressure, causes the water in closestool to flow back, and the active force below baffle is greater than baffle upper surface, moves up baffle,
Cause baffle to fit closely with the sealing ring on concave ring in inside cavity, plays the work for preventing closestool aqueous reflux to water supply line
With.
Detailed description of the invention
Fig. 1 is the schematic view of the front view of the utility model.
In figure: 1. baffles, 2. sealing rings, 3. handles, 4. supporting ribs, 5. guide rods, 6. springs, 7. cavitys, 8. angle valve ontologies,
9. interconnecting piece, concave ring in 10..
Specific embodiment
In order to make those skilled in the art more fully understand the technical solution of the utility model, with reference to the accompanying drawing
The utility model is described in further detail with most preferred embodiment.
As shown, the utility model includes angle valve ontology 8, the handle connecting with angle valve ontology 83, interconnecting piece 9 and returns only
Mechanism, angle valve ontology 8 include shell and spool, and spool is connected with external handle 3, and 8 upper side of angle valve ontology is equipped with into water
Hole, blasthole are connected with water supply line, and one end is equipped with apopore, and interconnecting piece 9, interconnecting piece 9 and closestool are connected with outside apopore
Pipeline is connected, and the blasthole and apopore of angle valve are connected with back locking mechanism at 90 degree of right angles above the blasthole, and described time
Locking mechanism includes hollow cavity 7, interior concave ring 10, baffle 1, spring 6 and supporting rib 4, and 7 lower end of cavity is connected with supporting rib
4,4 upper surface of supporting rib is connected with guide rod 5, and 5 channel of guide rod is provided on the baffle 1, and 5 upper end of guide rod passes through guide rod
5 channels, 5 outside disc of guide rod are equipped with spring 6, and 6 both ends of spring and baffle 1 and supporting rib 4 are affixed, 7 medial surface of cavity
Middle part is equipped with interior concave ring 10, and interior 10 downside of concave ring is provided with annular groove, is connected with sealing ring inside the annular groove
2, the spring 6 resists baffle 1, fits closely baffle 1 with 2 lower surface of sealing ring in annular groove.
Due to being connected with back locking mechanism above blasthole, when angle valve is opened, the water flow in water supply line is downward to baffle 1
Active force be greater than the active force upward to baffle 1 of spring 6, open non-return mechanism, water supply line gives closestool to supply water, when cutting off the water
Perhaps the moment that valve or tap are opened after resuming water supply again when larger fluctuation occurs for hydraulic pressure, can make in water supply line
Instantaneous negative pressure is generated, the water in closestool is caused to flow back, the active force of 1 lower section of baffle is greater than 1 upper surface of baffle, keeps baffle 1 upward
It is mobile, cause baffle 1 to fit closely with the sealing ring 2 on concave ring 10 in 7 inside of cavity, plays and prevent closestool aqueous reflux to water supply
The effect of pipeline.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the protection scope of the utility model.
