Abstract
The utility model relates to a conical surface upper sealing type outdoor fire hydrant. A valve body is fixedly connected with a hydrant body. An outer interface is arranged on the hydrant body. A valve seat is arranged inside the valve body. A valve clack is connected with a switch lever. The switch lever is controlled by a switch nut of the head of a hydrant cap to move upwards and downwards. The utility model is characterized in that the valve body and the hydrant body are connected in a right angle; the valve clack is fixed with a guiding pressing sleeve sheathed and matched with the inner wall of the valve seat together by a pressing nut; one side of the valve clack, which is positioned in the water inlet upstream direction of the valve seat, is matched with the valve seat through a sealing ring; a drain valve is also arranged on the valve body. The utility model has the advantages of labor saving for closing the fire hydrant, long service life, small size, light weight, good sealing performance, low cost, and convenient installation. The utility model does not need elbows.
Description
The utility model relates to the fire hydrant that a kind of fire-fighting is used.
Fire hydrant is a fire fighting device indispensable in the building group, and its effect is: 1, water receiving band, hydraulic giant can directly be put out a fire; 2, provide the water source to fire fighting truck.National Specification, outdoor fire hydrant have two kinds of ground type and underground types, are divided into three kinds of DN65, DN100, DN150 by bore.At present the outdoor fire hydrant of producing is and presses down sealedly, and when fire hydrant cut out, rotary screw compressed flap downwards, blocks valve seat, realizes closing.The shortcoming of this mode be flap in valve seat water outlet downstream direction one side, flap sails against the stream when closing, and need overcome hydraulic pressure, effort very, sealing gasket stressed big, friction is big, the life-span is short; Need elbow between valve body and the key, volume is big, heavy.
The purpose of this utility model provides a kind of very labour-saving conical surface upper sealing type outdoor fire hydrant of closing, and increases the service life, and reduces volume and weight.
The technical scheme of the utility model conical surface upper sealing type outdoor fire hydrant: valve body is fixedlyed connected with key, external tapping is arranged on the key, valve seat is arranged in valve body, flap is connected with switch lever, switch lever is moved up and down by the switch nut control of bolt cap head, it is characterized in that, valve body at right angles is connected with key, flap is fixed together with the guiding gland that cooperates in the valve base inner wall socket by clamp nut, be positioned at valve seat water inlet updrift side one side, and match with valve seat through sealing ring, also have drain valve on the valve body.Sealing ring is embedded between flap and the guiding gland edge.
Sealing ring is embedded between flap and the guiding gland edge.
The contact-making surface of sealing ring between valve seat and flap is the conical surface.
In the little valve body of drain valve valve port is arranged, the steel ball by spring apical grafting valve port position has sealing gasket between steel ball and the valve port, and the disengagement extreme position of steel ball is determined by the ring washer of valve body water outlet.
The course of work of the present utility model: be rotated counterclockwise switch nut, switch lever, move down and make the black box of forming by switch lever, guiding gland, flap, sealing ring clamp nut to moving down, when the switch nut revolves when motionless, runner is all opened, and current are external by the valve seat flow valves.The switch nut that turns clockwise after hours, at this moment black box rises under the drive of switch lever, realizes closing up to compressing with valve seat.Drain valve can discharge surplus water, avoids the key vibration.
Advantage of the present utility model: laborsaving when closing, because closing direction is consistent with water (flow) direction, just can close by hydraulic pressure; Valve body is a conical surface seal angie type valve, and valve body at right angles is connected with key, does not need elbow in addition, has further alleviated weight; Sealing gasket and seat design are conical surface seal, and the conical surface is not easy to accumulate foreign material, sealing gasket is not caused damage, and not friction between sealing gasket and the valve seat simultaneously, so conical surface seal can increase the service life 5～8 times than original press-down type.Because the change of seal form is guaranteeing that valve diameter is reduced to Φ 130mm by Φ 170mm, has dwindled volume, has alleviated weight under the constant prerequisite of flow.Original leather cup interlock drain valve is changed into the automatic drainage valve, close automatically during this valve＞0.02MPa, open automatically during＜0.02MPa, do not need the manual control switch, solved the phenomenon that fits badly after the former leather cup wearing and tearing.The utility model guaranteeing under the constant condition of serviceability, volume and weight all had very big dwindle and alleviate, as DN100 type outdoor fire hydrant original weight 130kg, now be 77kg, can save raw material 59%, reduced cost, also be convenient to install, ground, underground hydrant all are suitable for.
Below in conjunction with drawings and Examples the utility model is described in detail:
Fig. 1 is the structural representation of the outdoor post fire hydrant of the utility model conical surface upper sealing type.
Fig. 2 is the structural representation of the outdoor underground hydrant of the utility model conical surface upper sealing type.
Fig. 3 is the structural representation of drain valve.
As Fig. 1, shown in 2, conical surface upper sealing type outdoor fire hydrant, valve body 17 is fixedlyed connected by bolt 9 with key 7, key 7 is connected by hold-down bolt 3 with bolt cap 2, DN100 external tapping 6 is arranged on the key 7, DN65 external tapping 18 and chain hole 5, valve seat 13 is arranged in valve body 17, valve seat 13 matches with flap 15 through sealing ring 12, flap 15 is connected with switch lever 8, switch lever 8 is moved up and down by switch nut 1 control of bolt cap 2 heads, between hold-down bolt 3 and the key 17 O RunddichtringO 4 is arranged, also have drain valve 10 on the valve body 17, valve body 17 at right angles is connected with key 7, and flap 15 is in valve seat 13 water inlet updrift sides one side, flap is fixed together with the guiding gland 11 that cooperates in valve seat 13 inwall sockets by clamp nut 16, and sealing ring 12 contact-making surfaces between valve seat 13 and the flap 15 are conical surfaces.Sealing ring 12 is embedded between flap 15 and guiding gland 11 edges.
