Description
Technical field
The utility model relates to a kind of high low pressure switching valve, particularly relates to a kind of mechanical linkage formula high low pressure switching valve.
Background technique
In the production process, the sprinkling of the high low pressure liquid that often need hocket, and synchronism, interlocking capability when at present high low pressure liquid switches are all not high enough, but also can produce problems such as operation is unreliable, human configuration is more.
Therefore, be necessary to design a kind of high low pressure switching valve of high low pressure liquid that can switch fast and efficiently to overcome above-mentioned defective in fact.
The model utility content
The purpose of high low pressure switching valve of the present utility model is to realize switching fast and efficiently the sprinkling of height setting-out or other high low pressure liquid.
In order to achieve the above object, high low pressure switching valve of the present utility model is design like this:
A kind of high low pressure switching valve, this high low pressure switching valve comprise the low-pressure intake that is positioned at the valve body top, are provided with a low pressure flap in this low-pressure intake; Be positioned at the high pressure intake on right side, valve body below, be provided with a high pressure flap in this high pressure intake; Be positioned at the water outlet of valve body lower bottom part; Valve pocket with described low-pressure intake, high pressure intake, the equal conducting of water outlet; And the push rod that is connected with described high pressure flap.
As preferred implementation, described push rod is a hydraulic push rod.
As preferred implementation, described low pressure flap and high pressure flap are made by stainless steel material.
As preferred implementation, described low pressure flap and high pressure flap are made by anticorrosive stainless steel material.
As preferred implementation, described low pressure flap and high pressure flap are made by 316L type stainless steel or two-phase stainless steel.
The beneficial effect of high low pressure switching valve of the present utility model is: the switching in the time of can realizing height setting-out or other high low pressure spray liquid fast and efficiently, use high low pressure switching valve of the present utility model to make automaticity, synchronism and interlocking capability when liquid switches all have significant improvement, can also save manpower in addition, enhance productivity.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified, wherein identical components and parts are represented with identical reference character:
Fig. 1 is the sectional view of high low pressure switching valve of the present utility model.
Embodiment
Need to prove, describe below the word " preceding " that uses, " back ", " left side ", " right side ", " on ", D score and synonym thereof refer to the direction in the accompanying drawing, word " interior " and " outward " and synonym thereof refer to respectively towards or away from the direction of the utility model or its specific features geometrical center.
See also Fig. 1, high low pressure switching valve 1 of the present utility model comprises the low-pressure intake 10 that is positioned at the valve body top, is provided with a low pressure flap 11 in this low-pressure intake 10; Be positioned at the high pressure intake 12 on right side, valve body below, be provided with a high pressure flap 13 in this high pressure intake 12; Be positioned at the water outlet 14 of valve body lower bottom part; Valve pocket 15 with described low-pressure intake 10, high pressure intake 12, water outlet 14 equal conductings; And the push rod 16 that is connected with described high pressure flap 13.Preferably, described push rod 16 is hydraulic push rods.
It will be understood by those skilled in the art that described low pressure flap 11 and high pressure flap 13 should adopt the stainless steel material manufacturing of good airproof performance, for example 316L type stainless steel or two phase stainless steel etc.Preferably, described low pressure flap 11 and high pressure flap 13 adopt 316L type stainless steel material to make, for use in the sprinkling of corrosive liquids.
The working mechanism of high low pressure switching valve 1 of the present utility model specifically describes as follows:
When high low pressure switching valve 1 of the present utility model is in normal state, can spray low-pressure water from described water outlet 14, low-pressure water enters and pushes open low pressure flap 11 from described low-pressure intake 10, through valve pocket 15, enters the sprinkling pipeline by water outlet 14 at last.
When needs spray high pressure water, promote push rod 16 by artificial or automatic, this push rod 16 can be pushed high pressure flap 13 open, this moment, high pressure water just can be from the high pressure intake 12 enters valve pocket 15, valve pocket 15 pressure inside raise, low pressure flap 11 can be pushed closure naturally under the effect of valve pocket 15 internal pressures, high pressure water just can enter the sprinkling pipeline through water outlet 14 and realize spraying water with high pressure.When not needing to spray high pressure water, by artificial or automatic pulling push rod 16, this push rod 16 can be closed high pressure flap 13, this moment, valve pocket 15 pressure inside reduced, low pressure flap 11 can be unlocked under the effect of low-pressure water naturally, and low-pressure water just can enter valve pocket 15 and enter the sprinkling pipeline through water outlet 14 and realize the low pressure water spray.
It will be appreciated by those skilled in the art that, though explain as spraying object with water in the foregoing description, but high low pressure switching valve 1 of the present utility model also can be used for the sprinkling of other liquid fully, and according to the etching characteristic of liquid, selects corresponding corrosion-resistant or abrasion-proof stainless steel.
The utility model is described in detail in conjunction with its specific embodiment; and the foregoing description is only for the usefulness that the utility model is described; and be not to be to restriction of the present utility model; the those of ordinary skill in relevant technologies field; under the situation that does not break away from the open scope of the utility model; can also make various variations and modification, so all technological schemes that are equal to, comprise the change that all do not deviate from the utility model spirit and scope and revise all within the scope of the utility model protection.
