Description
Technical field
The present invention relates to fluid control valve, particularly a kind of multifunctional filtering type bi-directional expansion theft-proof gate valve.
Background technique
Now, theft-proof gate valve has been widely used in tap water and heating field, theft-proof gate valve is generally arranged on water meter or calorimeter front end, the effect of water supply or heat supply is cut off when can play antitheft or user's malicious owing fee, theft-proof gate valve is in the market all more single, the demand of user cannot be met, all could must open or throttle down by magnetic key during opening anti-theft gate valve, use is restricted, because the manufacture cost of magnetic key is higher, generally a lot of magnetic lock ball valves just join a magnetic key, and pipeline is all generally be in normal operating condition, occur that the situation of malicious owing fee still occupies the minority, in the most of time that pipeline normally uses, once damaging appears in pipeline, common gate valve can not be worked as use, theft-proof gate valve cannot be closed in time, there will be cold on the one hand, the waste of hot water, make troubles to maintenance work on the other hand, simultaneously during existing theft-proof gate valve work, the on-off action of cut-off water or other flow of fluid can only be played, filtering function be there is no to the impurity existed in water and other liquid and dirt, increase filtrating equipment is also needed at starting point or to the branch road that medium free from admixture requires, carry out the residue in barrier fluid, and increase the junction point of pipeline, improve installation and maintenance cost simultaneously, make troubles to workmen.
Existing filtration gate valve Chinese Patent Application No. as open on June 3rd, 2002 is the one " filter type gate valve " of 02235907.9, it is provided with handle, spool, valve body and filter screen, it has filtering function, existing filtration gate valve Chinese Patent Application No. as open on October 29th, 2010 is the one " filter-type gate valve " of 201020589099.0 again, comprise valve body, flashboard, liquid entering hole, liquid outlet and filter screen, equally only there is filtering function, valve cost is significantly increased from structural design according to above-mentioned two existing filtration gate valves, add raw material, good economic benefit can not be brought to user, also need to install by the direction of regulation, install cumbersome, time-consumingly to require great effort again, puzzlement is brought to user.
Common theft-proof gate valve only has anti-theft feature and does not have Expansion loose joint function, and when discovery duct length rear after Pipe installing is not enough, one is need to increase pipeline, increase the junction point of pipeline simultaneously, and increase leakage hidden trouble, two is need to change sufficiently long pipeline, now serious waste material, increases cost, because gate valve body is fixed installation formula, when installing and using, can not the length of regulation valve body according to actual needs, using scope is restricted, in addition, when this closure gate valve is installed along wall, closure gate valve need be done 360 degree to repeat rotation and tighten, other can be caused to install pipeline occur loosening, impact is leaked, and be subject to the restriction that wall gap is few, install, the valve gap above valve body and opening device first need be unloaded when changing and keep in repair, install, change extremely inconvenient, make troubles and loss to production and workmen, current existing Telescopic gate valve Chinese Patent Application No. as open on October 14th, 2011 is the one " a kind of magnetic locking telescopic gate valve " of 201120394034.5, comprise valve body 1, valve gap 2, open-shut device 3, valve rod 4, opening device 5, telescopic cover 6 and union nut 7, described valve gap 2 is located at above valve body 1, on described valve body 1, part is provided with water intake 11 and water outlet 12 vertically, described open-shut device 3 to be located in valve body between water intake 11 and water outlet 12, described valve rod 4 one end is connected with open-shut device 3 through valve gap 5, described opening device 5 is located on the free end of valve rod 4, the free end of described valve body 1 water outlet 12 is provided with slip restraining groove 13, described telescopic cover 6 is slidably located at valve body 1 water outlet 11 and is slided on restraining groove 13, that one end that described telescopic cover 6 contacts with slip restraining groove 13 is provided with spacing preiection 61, avoid telescopic cover 6 to depart from valve body 1, this structural design is reasonable not, telescopic cover 6 needs to be clouted by spacing preiection 61 with special tool after installing, spacing preiection 61 distending just can be blocked on slip restraining groove 13, manually beat owing to adopting, dynamics is uneven, uncontrollable, more telescopic cover is caused to be stuck, can not be free to slide, greatly improve reject rate.
Therefore, be necessary to be improved theft-proof gate valve, one is that theft-prevention structure improves: when pipeline during normal use, make the magnetic lock of theft-proof gate valve inoperative, theft-proof gate valve can be worked as common gate valve and be used, just can opening anti-theft gate valve by general tool, when pipeline occur usurping or malicious owing fee time allow the magnetic lock of theft-proof gate valve work, only just can open or close valve by special magnetic key; Two is filtering functions to theft-proof gate valve valve design, can make the more clean available protecting water meter of water quality and water appliance; Three is newly devise bi-directional expansion loose joint function to valve for guarding against theft valve body, and Pipe installing deficiency is compensated and can reduces leakage hidden trouble, the present invention produces thus.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of multifunctional filtering type bi-directional expansion theft-proof gate valve, reasonable in design of the present invention, have that bi-directional expansion loose joint and filtering function, easy installation and removal, cost are low, compensation of pipeline, theft-proof gate valve can be worked as use, also can work as common gate valve to use, use flexibly, Applicable scope is wider.
