Description

The thief-proof lock valve of heating system laser

Technical field

The utility model belongs to heat supply equipment in building trade, in particular to a kind of thief-proof locking of heating system laser Valve.

Background technique

China's heat supplying pipeline system is established in last century the nineties more, and heat supplying pipeline and system unit form whole Heating cycle.Since " urban heat supplying fee system reforms opinion ", one family of heat supply, one valve is gradually implemented, and lock valve is applied to Huge numbers of families.Previous lock valve mostly uses materials such as " copper, stainless steel, cast irons ", and the service life is short, wastes a large amount of metals.It is through excessive Year use, can frequently occur " can not open and close, open and close it is not flexible it is not in place, fall egg " phenomena such as, to heat supply, company is brought very It is mostly inconvenient, and old-fashioned locking valve arrangement is simple, and ordinary people can carry out opening operation, cause the loss of heat supply company heat source tight Weight, also results in very big economic loss.

Summary of the invention

The purpose of the utility model is to overcome above-mentioned technical deficiency, a kind of light weight, corrosion-resistant, anti-heat source loss are provided The good thief-proof lock valve of heating system laser of effect.

The utility model solve technical problem the technical solution adopted is that, the thief-proof lock valve of heating system laser includes: Valve body, core, ball bag body, ball bag body gland, its main feature is that: valve rod hole is equipped on a spherical surface of core, in valve rod hole Equipped with the valve rod on external end head being profound moon shape, o-ring groove is equipped on valve rod, it is close at valve rod with ball bag body joint face Seal groove is provided with sealing ring, and injection molding is equipped with lock in the valve body inner bore of valve rod periphery, and lock is equipped in lock inner hole The conical surface is crossed in the lock conical surface and wins cooperation equipped with the thief-proof chip of laser, and the thief-proof chip of laser is pasted by the H-shaped seating face of cast iron Laser anti-counterfeit patch, valve rod cooperate controlled valve by profound moon shape end and special key.

The beneficial effects of the utility model are: the thief-proof lock valve of heating system laser need to be dedicated using the thief-proof chip of laser The mating forcible entry of key, general tool can not be opened, and have two seals, and sealing effect is good, and valve body and core use corrosion resistant The material of erosion is made, and has the characteristics that good toughness, switch are flexible.Overall structure is light-weight, saves metal, long service life, has Good anti-theft function.

Detailed description of the invention

It is illustrated below in conjunction with attached drawing with embodiment.

Fig. 1 is the thief-proof lock valve structural front view of heating system laser.

Fig. 2 is that Fig. 1 is rotated by 90 ° A-A cross-sectional view.

Fig. 3 is the top view that Fig. 1 is rotated by 90 °.

In figure, 1- valve body；1-1- reinforcing rib；2- ball bag body gland；3- ball bag body；4- core；4-1- valve rod hole；5- sealing Circle；6- valve rod；The thief-proof chip of 7- laser；8- lock；The 8-1- lock conical surface.

Embodiment, referring to attached drawing 1~3, heating system is that middle part is set in the valve body 1 of three way type with the thief-proof lock valve of laser There is ball bag body 3, the upper surface of ball bag body 3 is equipped with ball bag body gland 2, and 2 center of ball bag body gland and 3 lower end center of ball bag body set through-hole It is connected to the upper and lower through-hole of valve body 1.Hollow in ball bag body 3 is provided with core 4, and valve rod is equipped at the right side center of core 4 Hole 4-1 is provided with valve rod 6 in valve rod hole 4-1, and two seals are equipped on the excircle of valve rod 6 Yu 3 junction of ball bag body Slot is provided with sealing ring 5 in seal groove, and profound moon shape is made in the right end of valve rod 6.The mistake on the right side inner hole wall of valve body 1 It is full of and is pressed with lock 8, lock conical surface 8-1 is equipped in the inner hole of lock 8, interference fit the swashing equipped with H-shaped in lock conical surface 8-1 The thief-proof chip 7 of light.The thief-proof chip 7 of laser is that laser anti-counterfeit patch, the thief-proof chip 7 of laser and valve are pasted by the H-shaped seating face of cast iron The valve seat conical surface 8-1 of seat 8 forms thief-proof barrier, the profound moon end switch valve of special key cooperation valve rod 6.On the right side of valve body 1 Face is equipped with symmetrical 4 reinforcing rib 1-1.Valve body 1 is made of PP-R modified polypropene material, is molded into copper lock 8 One, core 4 have good toughness using COPP co-polypropylene material, do not corrode characteristic.

The working principle of the utility model is: the thief-proof chip 7 of the laser of the thief-proof lock valve of heating system laser and lock 8 Cooperation is won using crossing, when using lock valve, the thief-proof chip 7 of laser must be dismantled and use special key switch valve, and valve rod 6 Top profound moon shape be made provide power for the switch rotary of core 4, general tool can not rotate, and realize anti-counterfeit anti-theft heat source function Energy.
