Description
Technical field
The utility model 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, can play antitheft or user's malicious owing fee time, cut off the effect of water supply or heat supply, theft-proof gate valve is in the market all more single, cannot meet user's demand, when opening anti-theft gate valve, all must could open or throttle down by magnetic key, use is restricted, because the manufacture cost of magnetic key is higher, general a lot of magnetic lock ball valves are just joined a magnetic key, and pipeline is all generally in normal operating condition, the situation that occurs malicious owing fee still occupies the minority, in the normal most of time using of pipeline, once damaging appears in pipeline, can not work as common gate valve uses, cannot close in time theft-proof gate valve, there will be on the one hand cold, the waste of hot water, to maintenance, work makes troubles on the other hand, when simultaneously existing theft-proof gate valve work, can only play the on-off action of cut-off water or other flow of fluid, the impurity and the dirt that in water and other liquid, exist be there is no to filtering function, the branch road requiring at starting point or to medium free from admixture also needs to increase a filtrating equipment, carry out the residue in barrier fluid, and increase the junction point of pipeline, installation and maintenance cost have been improved simultaneously, make troubles to workmen.
The one " filter type gate valve " that existing filtration gate valve Chinese Patent Application No. as open on June 3rd, 2002 is 02235907.9, it is provided with handle, spool, valve body and filter screen, it has filtering function, the one " filter-type gate valve " that existing filtration gate valve Chinese Patent Application No. as open on October 29th, 2010 is 201020589099.0 again, comprise valve body, flashboard, liquid entering hole, liquid outlet and filter screen, equally only there is filtering function, obviously increase valve cost according to above-mentioned two existing filtration gate valves from structural design, increase raw material, can not bring good economic benefit to user, also need direction in accordance with regulations to install, install cumbersome, time-consuming effort again, bring puzzlement to user.
Common theft-proof gate valve only has anti-theft feature and does not have Expansion loose joint function, and in the time that pipeline is installed rear discovery duct length deficiency, the one, need to increase pipeline, increase the junction point of pipeline simultaneously, and increase the hidden danger of leaking, the 2nd, need to change sufficiently long pipeline, now serious waste material, increases cost, because gate valve body is fixed installation formula, in the time installing and using, the length of regulation valve body according to actual needs, in using scope, be restricted, in addition, when this closure gate valve is installed along wall, closure gate valve need be done 360 degree repeat rotation tighten, can cause that other install pipeline and occur loosening, impact is leaked, and be subject to the restriction that wall gap is few, install, when changing and keeping in repair, need first unload valve gap and the opening device of valve body top, install, change extremely inconvenient, make troubles and lose to production and workmen, the one " a kind of magnetic locking telescopic gate valve " that current existing Telescopic gate valve Chinese Patent Application No. as open on October 14th, 2011 is 201120394034.5, as Figure 15 comprises 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 valve body 1 ' top, on described valve body 1 ', part is provided with water intake 11 ' and water outlet 12 ' vertically, described open-shut device 3 ' is located between the interior water intake 11 ' of valve body 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 on valve body 1 ' water outlet 11 ' slip 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 ' and valve body 1 ' to depart from, this structural design is reasonable not, telescopic cover 6 ' needs with special tool, spacing preiection 61 ' to be clouted after installing, spacing preiection 61 ' distending just can be blocked on slip restraining groove 13 ', manually beat owing to adopting, dynamics inequality, uncontrollable, cause more telescopic cover to be stuck, can not be free to slide, greatly improve reject rate.
Therefore, be necessary theft-proof gate valve to be improved, the one, 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 occurs usurping or allows the magnetic lock of theft-proof gate valve work when malicious owing fee, only just can open or close valve by special magnetic key; The 2nd, theft-proof gate valve valve body has been designed to filtering function, can make the more clean effective protection water meter of water quality and water appliance; The 3rd, valve for guarding against theft valve body has newly been designed to bi-directional expansion loose joint function, make pipeline that deficiency is installed and be compensated and can reduce the hidden danger of leaking, the utility model produces thus.
