Abstract
The invention relates to a pipeline frost valve, which realizes the automatic opening and closing of a valve by applying a memory spring capable of automatically changing stress along with the temperature change in the valve and matching with the switch of a pilot valve; when the temperature is lower than 3 ℃, the memory spring can automatically contract to drive the movable column to lift upwards along the sliding channel, the water flow in the valve cavity reaches the downstream of the valve through the guide pipe, the valve is opened, and the stored water in the pipeline is discharged, so that the aim of preventing the pipeline from being frozen is fulfilled; when the temperature exceeds 3 ℃, the memory spring can automatically extend to drive the movable column to move downwards along the sliding channel, water enters the valve cavity through the guide valve, the valve is automatically closed, and the pipeline system normally operates.
Description
Technical field
The present invention relates to a kind of freezing prevention tubing valve, specifically a kind of automatically quick drain valve for preventing that pipeline is freezing winter.
Technical background
For many hydraulic engineerings of north cold area, due to terrian condition and various requirement, pipeline is at various bends of underground formation etc., if the depth as shallow of buried depth ratio frozen soil layer, ducted water cannot be got rid of in time, when the temperature of pipeline soil layer is during lower than zero degree, the water in the full packages road that now cannot get rid of will build-up ice, certainly will make pipeline cruelly split, common solution is to build drainage sump, and the construction of a large amount of drainage sumps, not only to spend a large amount of funds, the labor management of system is also caused to a large amount of wastes simultaneously, the destruction of also easily causing system because of administrative staff's error.
At present both at home and abroad less to the device research that adopts hydraulic automatism to sluice, and use and inconvenient, such as adopt the temperature difference to sluice to protect expensive instrument etc., and generally adopt very traditional mode, carry out draining by artificial mode.Although also there is the patent application about antifreezing valve on a small quantity, but mostly adopt for surface water supply, also need manually to control on ground simultaneously, as: Chinese patent (patent No.: zL200420047593.9) discloses a kind of solution sampling anti-freezing valve for internal fixed outer thermal insulation pipeline, mainly solves the problem of existing sample cock easy freezing.Chinese patent (patent No.: zL200520087076.9) discloses a kind of antifreezing valve, valve body can be able to be embedded in undergroundly when use, relies on surface soil insulation, and these valve mechanism relative complex, is also unfavorable for that Underground Long-term is embedding.Chinese patent (patent No.: zL200910180769.5) discloses a kind of freezing prevention tubing valve, also valve body can be embedded in underground, but because draining is too slow, the draining of main dependence pressure compensating emitter, and all the time in hull-borne, the water displacement source of wasting water too greatly, the too little effect that do not have again, causes Applicable scope too narrow.
Summary of the invention
In the time that existing seasonal pipeline water delivery, northern low temperature area causes pipeline burst problem because temperature is too low, for too much employing drainage sump or pipeline is embedded in to frozen soil layer causes below engineering work load huge, cost is high and manage extremely inconvenient problem, simultaneously existing frost valve mainly uses on high-precision end instrument equipment cost high, using scope is narrower and be not suitable for the deficiency of applying on pipeline, the invention provides a kind of simple in structure, activity freely, and the valve of the automatically quick water releasing and freezing prevention of the pipeline of durable, energy fast opening/closing valve, gush the current in pipeline, prevent pipeline burst.
The invention provides a kind of freezing prevention tubing valve, it is made up of valve A, conduit B, pilot valve C;
Wherein valve A comprises valve handle A1, spring A2, valve gap A3, valve pocket A4, barrier film A5, valve A 6; Barrier film A5, the valve gap A3 that wherein valve A 6 tops are connecting and surround the valve pocket A4 forming by barrier film A5 and valve gap A3, valve gap A3 top is valve handle A1, there is spring A2 valve pocket A4 inside, and the two ends of spring A2 are connecting respectively valve handle A1 and barrier film A5, valve A 6 and valve pocket A4 are divided into two independently spaces by barrier film A5, and the surface area that barrier film A5 connects valve pocket A4 is greater than the surface area that connects valve body A6, and barrier film A5 is by moving up and down to realize the opening and closing of valve A 6;
Wherein pilot valve C comprises hold-doun nut C1, lower spring stabilizer C2, snubber C3, limits baffle plate C4, rubber sheet gasket C5, boss baffle plate C6, mobile post C7, regulator bolts C9, upper shell C10, upper spring stabilizer C12, memory spring C13, lower casing C17; Boss C14 is arranged at upper shell C10 bottom; Water groove C8 was arranged at the bottom of mobile post C7, and the shape of crossing water groove C8 is top two tapers that are docking together; It is that outlet C22, side have the entrance C19 and the outlet C20 that communicate with sliding channel C18 that lower casing C17 has the end of upper lower logical sliding channel C18, a sliding channel C18; The upper restriction baffle plate C4 installing of mobile post C7 moves up and down in the space of snubber C3 and lower casing C17 encirclement, thereby drives mobile post C7 to move up and down; Regulator bolts C9 moves in upper shell C10 upper end perforate, thereby regulates the stress intensity of memory spring C13, and regulator bolts C9 is preferably connected by engage thread with upper shell C10; Lower casing C17 is connected to the lower end of shell C10, in the middle of both, be snubber C3, snubber C3 upper end perforate is played restriction and is limited the effect that baffle plate C6 moves upward, snubber C3 plays lower end the effect at fixing rubber sheet gasket C5 edge, and the Placement of lower casing C17 and upper shell C10 is preferably threaded;
Wherein conduit B comprise from pilot valve C outlet C22 to the conduit B1 of valve downstream, from pilot valve C outlet C20 to the conduit B2 of valve pocket A4, swim over to the conduit B3 of pilot valve C entrance C19 from valve A;
Alternatively, the shape of crossing water groove C8 can be other shape that diameter is less than mobile post C7, as cylinder type.
Preferably, each conduit B is high pressure resistant ABS plastic pipe.
The STRESS VARIATION critical value of the memory spring (C13) in pilot valve (C) is lower than 5 degrees Celsius, preferably 3 degrees Celsius.
The working principle of valve involved in the present invention is: in frost valve, memory spring C13 is in the time of critical temperature, critical stress instantaneous variation, cause spring moment telescopic variation, the telescopic variation of memory spring C13 drives mobile post C7 to move up and down in sliding channel, thereby control entrance C19, the outlet C20 of pilot valve C, the switch of outlet C22, the on off state of entrance C19, outlet C20, outlet C22, cause the switch of the valve A being attached thereto by conduit B, whether gush thereby realized the current of controlling in pipeline, finally reached the object of freezing prevention tubing.
The beneficial effect of freezing prevention tubing valve involved in the present invention is as follows:
(1) adopt memory spring, adjust stress and the length of spring according to the variation of temperature, utilize the characteristic of critical stress (corresponding critical temperature) instantaneous variation of memory spring, realize the moment unlatching of frost valve, the feature of closing, can complete automation antifreezing effect.
(2) frost valve pilot valve structure simplicity of design, exquisiteness, meets the movement process of memory spring, has limited again the overreaction of memory spring, has ensured the normal function of memory spring.
(3) valve A, by the spring A2 that uses valve handle A1 and be attached thereto, has reduced the startup working pressure causing due to the mechanical reason of valve itself, has expanded the Applicable scope of frost valve.
