Abstract

The utility model relates to a valve for discharging and closing water, comprising a T-shaped valve body. The rod body of a valve rod is sheathed with a spring. The lower end of the valve rod is riveted with a valve, and is sheathed in a sealing sleeve. The sealing sleeve is arranged in a vertical hole of the valve body. The utility model has the advantages of simple structure, small size, material saving, convenient and rapid water discharging and closing and flow quantity control, no water leakage and water overflowing when in use, and long-term reliable working.

Description

Valve

The utility model relates to a kind of plumbing, and it is for being contained on the tap water pipe line as discharging water and a kind of valve of Guan Shuiyong.

At present, on the tap water pipe line at home and abroad, be used for discharging water and close the valve of water, normally stop valve and ball valve are two kinds: stop valve is to make valve opening and closing by the threaded valve rod of rotating band.Its He Guanshui that discharges water is very slow, not very convenient, and after using a period of time, the filler between valve rod and the valve gap can be damaged, and the slit occurs.Water can be emerged from this slit and be caused waste.Though ball valve discharges water and closes water conveniently rapidly.But its difficulty of processing is big, and price is higher, and the controlled water flow amount is all not too convenient simultaneously.

The purpose of this utility model is to avoid above-mentioned deficiency of the prior art, and a kind of volume is little, simple in structure, easy processing and provide, and discharges water, Guan Shui and controlled water flow amount be all very convenient rapidly, and does not metal run out, do not emit the pipeline valve of water all the time.

The purpose of this utility model can reach by following measure: this valve is to be made of valve body, Steel Washer, valve gap, rivet, handle, valve rod, stuffing box gland, spring, valve.The external form of valve body is " ⊥ " shape, and there are two crossing holes the inside, and the hole of its substantially horizontal is the port hole of into water and water outlet, and the hole of vertical is a blind hole.The shape of valve rod is the cylindrical body that an end has little round platform.The valve of its lower end and a tapered disk shape is riveted together, and simultaneously spring is set on the cylindrical body of valve rod, and the parts that valve rod, valve are formed with spring are inserted in the stuffing box gland then, and are nested with Steel Washer at the annular groove of stuffing box gland cylindrical.Stuffing box gland is positioned at the vertical hole of valve body.The upper end of valve rod is passed middle the having of an end face and is worn groove, and there is the endoporus of the valve gap of helicoid boss on both sides, use rivet and handle hinged again.

Valve gap of the present utility model can also be two round platform rank by cylindrical, has groove on it in the middle of the round platform upper-end surface, and it is 90 °～180 ° arc groove that the lower end surface has central angle; Following round platform cylindrical has trapezoidal thread; The center is the spiral cover of through hole.The cage ring that has the vertical banking stop constitutes with having the sealing cover in trapezoidal internal thread hole.

The drawing of accompanying drawing is described as follows:

Fig. 1 is a structural drawing of the present utility model.

Fig. 2 is the plan view of Fig. 1.

Fig. 3 is the structural drawing of combined valve cover.

Fig. 4 is the punching parts figure of cage ring.

The utility model is described in further detail below in conjunction with embodiment: valve body (1) is cast as " ⊥ " shape.The annular groove of laying its periphery in its vertical hole is embedded with the stuffing box gland (7) of Steel Washer (2).Simultaneously laying shaft in stuffing box gland (7) and be with spring (8), the lower end riveting has the valve rod (6) of tapered disk shape valve (9).The upper end of valve rod (6) is the endoporus that passes valve gap (3), uses rivet (4) and handle (5) hinged then.Valve gap (3) can be to have in the middle of its end face to wear groove, and both sides have the protruding overall structure of closing of helicoid, also can be the assemblying bodys that is made of spiral cover (10), the cage ring (11) that has banking stop (13) and sealing cover (12).

When using this valve, only with hand is pressed handle lightly to next, so the valve rod that links to each other with handle overcomes the elastic force of spring, moves upward together with stuffing box gland.Separate with the dewatering outlet sealing termination of stuffing box gland, the annular space occurs, and water just enters into water outlet from water intake.As long as with hand one pine, valve rod and stuffing box gland move downward under the effect of spring together, and the termination of stuffing box gland and dewatering outlet are adjacent to, and the pressure of adding tap water can make Feng Degeng jail, dewatering outlet, accomplishes watertight.And valve rod do not contact with water in the course of the work all the time with spring, so just guarantees that valve rod and spring are lost by scale never.If waterdrainage amount is bigger, only need handle is upwards stirred 90 °, just can allow handle steadily be in straight up position, this moment standard-sized sheet dewatering outlet and discharging water, and Guan Shuishi moves back to horizontal position with handle, just can similarly close water.If control and when regulating streamflow, after just handle being changeed an angle slightly in horizontal plane, valve rod and the stuffing box gland different height that can rise according to the size of institute's gyration, thereby the annular space that occurs varying in size at the place, dewatering outlet are so reach required streamflow.

The utility model has following advantage compared to existing technology: this valve mechanism is simple, volume is little, can save a large amount of raw material, discharge water, Guan Shui and control flow all easily rapidly, seal solid and reliable, do not metal run out, do not emit water, valve rod does not contact with water at work all the time with spring, can work stably in a long term.

Claims

1, a kind of valve that is made of valve body (1), Steel Washer (2), valve gap (3), rivet (4), handle (5), valve rod (6), stuffing box gland (7), spring (8) and valve (9) is characterized in that the profile of valve body (1) is " ⊥ " shape; Valve rod (6) is the cylindrical body that the lower end has little round platform, be with spring (8) on its shaft, the parts that valve (9) valve rod (6), spring (8) and valve (9) composition of a tapered disk shape are being riveted in the lower end are inserted in the stuffing box gland (7) that is placed in valve body (1) the vertical hole; The hole of valve gap (3) is passed in the upper end that stuffing box gland (7) periphery annular groove is being nested with Steel Washer (2) valve rod (6), uses rivet (4) and handle (5) hinged again.
