Abstract
A multi-purpose water pump adapter comprises a bolt body and a control valve; a water band interface controlled by the control valve and an interface mouth cover covering the water band interface are arranged on the bolt body; the multi-purpose water pump adapter further comprises a pressure release valve mounted on the bolt body; the pressure release valve comprises a valve body, a spring and a sphere; the valve body comprises a hollow valve post and a cover body covering one end of the valve post; the cover body is provided with a water outlet; a water inlet is formed on the other end surface of the valve post; a first pressure release channel and a second pressure release channel which are communicated with the water inlet and the water outlet respectively are formed in the valve post; the clear opening of the first pressure release channel is larger than that of the second pressure release channel; a step face is formed between the first pressure release channel and the second pressure release channel; a sealing gasket is arranged on the step face; the sphere and the spring are placed in the first pressure release channel; and one end of the spring is propped against the cover body, and the other end is propped against the sphere. By adopting the design of the pressure release valve, when water in a water pipe channel flows into the water pump adapter, and the water pressure is overlarge, the pressure can be released through the pressure release valve.
Description
Technical field
The utility model relates to a kind of fire hydrant, specifically is meant the formula siamese fire department connections of using more, and it is the special-purpose fire-fighting equipment of the supporting high rise building water supply of fire-fighting power pump.
Background technology
Fire hydrant is the fire-fighting instrument, and it mainly acts on is control combustible, isolated oxidizer, eliminate ignition source.Existing fire pump adapter is of a great variety, has many with formula, ground type, underground type etc.With many uses formula siamese fire department connection is example, and the master control valve that its structure comprises key and has handwheel, this key are provided with hose coupling and the interface that is used to be covered on the hose coupling is chewed lid, this master control valve control hose coupling water outlet.During use, rotation hand wheel makes the master control valve open, for fire demand water.
Above-mentioned siamese fire department connection in use, the part that can come with some shortcomings is when water in the water pipe channel gets into siamese fire department connection; Hydraulic pressure is prone to change; Existing siamese fire department connection can not guarantee the water inlet pressure stability, therefore can not satisfy actual use needs, particularly when water inlet pressure is higher; Cause the hose coupling superpressure, influence fire-fighting work and normally carry out.
The utility model content
Use formula siamese fire department connection, its main purpose to be to overcome existing siamese fire department connection more the utility model provides and to guarantee the hose coupling pressure stability, be prone to influence the shortcoming that fire-fighting work normally carries out.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
Use the formula siamese fire department connection more, comprise key and by-pass valve control, this key is provided with the hose coupling that is controlled by by-pass valve control and the interface that is used to be covered on the hose coupling is chewed lid; Also comprise the relief valve that is installed on the key, this draining valve comprises valve body, spring and spheroid, and this valve body comprises the valve rod of hollow and the lid that is covered on valve rod one end; This lid is provided with discharge outlet; This valve rod other end offers water inlet, forms first, second pressure release passage that communicates with water inlet and discharge outlet respectively in this valve rod and constitutes, and the latus rectum of this first pressure release passage is greater than the latus rectum of second pressure release passage; Form a step surface between it; Pad is established a gasket seal on this step surface, and said spheroid places in first pressure release passage, and said spring also places in first pressure release passage; And an end contacts on the lid, and the other end contacts on the spheroid.
Aforementioned gasket seal is a rubber sheet gasketing.
Aforementioned spheroid is a glass marble.
Can know by above-mentioned description, compare, the utlity model has following advantage: adopt the design of relief valve with prior art to the utility model structure; When the water in the water pipe channel gets into siamese fire department connection, when hydraulic pressure is excessive, can carry out pressure release through relief valve; The water inlet pressure stability of siamese fire department connection; Satisfy actual use needs, hose coupling can superpressure, has guaranteed that fire-fighting work normally carries out.The operation principle of this relief valve does; Open by-pass valve control, water gets in the key, when the hydraulic pressure in the key is too high; Be the elastic force of hydraulic pressure pressure greater than spring; At this moment hydraulic pressure can be oppressed glass marble to moving away from the second pressure release passage direction, and promptly discharge outlet is opened, and ponding can be discharged through the discharge outlet on the lid; After the hydraulic pressure in the key was reduced to normal pressure, promptly hydraulic pressure pressure was less than the elastic force of spring, and at this moment elastic force can be oppressed the glass marble returning movement, makes glass marble push down gasket seal, and promptly discharge outlet is shut.

The specific embodiment
The specific embodiment of the utility model is described with reference to the accompanying drawings.
See figures.1.and.2.The formula siamese fire department connections of using more; It comprises key 1, relief valve 2 and the by-pass valve control 3 that has handwheel 30; This key 1 be provided with its in the pressure release interface that communicates of intake tunnel; This draining valve 2 is installed on the pressure release interface, also is provided with hose coupling 10 on this key 1 and is used to be covered on interface on the hose coupling 10 to chew and cover 11, these by-pass valve control 2 control hose couplings 10 water outlets.
With reference to Fig. 2, Fig. 3 and Fig. 4.Said draining valve 2 comprises valve body, spring 21 and spheroid 22, and this valve body comprises the valve rod 23 of hollow and the lid 24 that is covered on valve rod 23 1 ends, and this lid 24 is provided with discharge outlet 240; These valve rod 23 other ends offer water inlet 230, form first, second pressure release passage 231,232 that communicates with water inlet 230 and discharge outlet 240 respectively in this valve rod 23 and constitute, and the latus rectum of this first pressure release passage 231 is greater than the latus rectum of second pressure release passage 232; Form a step surface 233 between it; Pad is established a gasket seal 234 on this step surface 233, and said spheroid 22 places in first pressure release passage 231, and said spring 21 also places in first pressure release passage 231; And an end contacts on the lid 24; The other end contacts on the spheroid 22, and said gasket seal 234 is a rubber sheet gasketing, and said spheroid 22 is a glass marble.
