Description

The Three way type Valve with lock

The utility model relates to a kind of Three way type Valve with lock, particularly suitable is installed on the pipeline of heating equipment.

For a long time, resident's warming problem of " big-pot " of eating is heating department pain in the neck feelings always.Will thoroughly change traditional Heating Design mode, by a building or a unit, a control valve changes a family one valve into, and the air feed of paying dues or not and stopped the supple of gas or steam, and this just needs the realization that a kind of special valve guarantees this measure.The patent No. before the utility model is 99222999.5, the technology of by name " Valve with lock ", though with on the valve lock, but because project organization is loose, the connection part weakness of lock and valve body firmly just might rupture: outside keyhole is exposed to, do not satisfy the needs of insurance a little.

The purpose of this utility model is, provides a kind of reasonable in design, reliable performance, and simple in structure, cost is low, a kind of Three way type Valve with lock that under the situation that does not change original heating piping facility, can conveniently install, control.

Design proposal of the present utility model is that for guaranteeing that having the heating piping facility now does not destroy, under the situation that is not increasing other investment and convenient installation, control, valve body and valve stamen all are designed to Three way type; For guaranteeing that valve has good sealing effect, the valve stamen is designed to the cone cylinder type, and the adjustable lever of valve stamen lower end is provided with and is used for the adjusting nut of modulating valve stamen and Sealing tightness; Be locked in the valve rod center hole in the valve body, snap is contained in vertical with keyhole, and passes in the spring hole of being opened on lock wall, valve rod, trim ring and the valve body, makes the compact structure of its this valve, and firm, valve body can not be destroyed easily, the safety coefficient height; For preventing that further the behavior of stealing with gas from taking place, lockhole outside, the valve body upper end adds a loam cake again, valve body is relative with loam cake has plumbous sealing hole, seals with lead sealing, reaches secondary and insures.

Compared with the prior art Three way type Valve with lock of the present utility model has compact structure, characteristics firm, fragile, not easy for installation.As long as install before every group of heating installation movable joint, the pipeline between the upper and lower building directly connects, and can reach branch family, locellus heating.Save time, laborsaving, saving fund, and do not destroy the existing decorative environment of indoor and outdoor.The realization of this Three way type Valve with lock, for heating work progressively by the welfare type to the commercialization transition, feasible technical measures are provided.

Accompanying drawing 1 is the structural representation of Three way type Valve with lock.

Accompanying drawing 2 is the left view of accompanying drawing 1.

For structure of the present utility model is had further understanding, details are as follows in conjunction with specific embodiment of the utility model:

Embodiment, the Three way type Valve with lock.

With reference to accompanying drawing 1,2, the structure of Three way type Valve with lock of the present utility model is, fix a top at valve body [1] inner chamber of Three way type by Sealing [2] and having groove, the bottom has adjusting screw rod, is the valve stamen [3] that has three through holes on 0 °, 90 °, the 180 ° positions on cone cylinder type surface.The groove of valve stamen [3] cooperates and is connected as a single entity with the valve rod [4] of its top.Valve rod [4] outside is to prevent the upper and lower mobile trim ring of valve rod [4] [5] by screw thread being used for fixing of being connected with valve body [1].Lock [7] is located in the heart hole of valve rod [4], and snap [6] is contained in vertical with keyhole, and passes in the spring hole of being opened on lock wall, valve rod [4], trim ring [5], the valve body [1].[8] be key.Outside lockhole, valve body [1] upper end is by the loam cake that is being threaded [9], and loam cake [9] is relative with valve body [1] has plumbous sealing hole [12].On the adjustable lever of valve stamen [3] bottom of stretching out valve body [1], be provided with an adjusting nut [10].[11] be one with valve body [1] into and out of the outer threaded three-way interface that is provided with of the relative 90 ° of positions of pipe.

Use operating process: at first screw off loam cake [9], insert key [8], lock [7] is opened, make valve be in opening state (when becoming 180 °, directly thermal source being fed radiator), extract key [8] then, screw loam cake [9], seal at plumbous sealing hole [12] with lead sealing.

(when becoming 90 °, make thermal source not feed radiator, directly flow away from the bypass tube station, radiator is not worked) extracts key [8] when closing with Locked valve, screws loam cake [9] and uses lead sealing, shuts at plumbous sealing hole [12].
