Description
Technical field
The utility model relates to fire-fighting equipment field, more specifically say a kind of two outlet of bivalve fire hydrants that can voltage stabilizing.
Background technology
Indoor fireplug is the indoor fixing fire fighting devices such as the interface of pipe network in house to delivery of water, Ta Shi factory, warehouse, skyscraper, public building and boats and ships, and it is arranged in fire-hydrant cabinet conventionally, supports the use with the fire-fighting equipment such as fire hose, Fire branch.
Traditional indoor fireplug does not possess pressure-reduced and-regulated function, can not control the flow of fire water, cause at the bottom of high-rise floor hydraulic pressure excessive, be unfavorable for the use of fire-fighting lance, because hydraulic pressure is excessive, the reaction force of fire-fighting lance is larger, and fire fighter is difficult for holding, if hydraulic giant is slipped out of the hand, the personnel that very easily cause injure.According to the regulation of GB50045-95 " Code for fire protection design of high rise buildings ", in the time that the pressure of fire hydrant bolt mouth exceedes 0.8MPa, must take measures to reduce stresses.
For head it off, common way has three kinds: (1) adopts separate water supply system, to reduce the pressure differential of fire hydrant water supply system, avoids the operating pressure of fire hydrant in the time that bottom floor is put out a fire to exceed instructions for use.The shortcoming of the method is: facility complexity, cost is high.(2) before superpressure fire hydrant, on arm, set up pressure reducing orifice.The shortcoming of the method is: theoretically in design calculate loaded down with trivial detailsly, install complicatedly in construction, cost is high, if once wrongly installed, can cause bad consequence.(3) at the water outlet of fire pump, sluicing pressure-reducing valve is set.The shortcoming of the method is: valve opening degree is difficult for, and water yield loss is large.
Current common a kind of fire hydrant that reduces pressure is, between the delivery port of common fire hydrant and interface, a pressure reducing orifice is set, and decides the pressure of water outlet of fire hydrant with the aperture of pressure reducing orifice.Although the method can play certain depressurization, pressure instability, and due to the pressure difference of different floor fire demand waters, the requirement in the aperture to pressure reducing orifice is also different, arranges and calculates cumbersome, and mounting means is more complicated also.And Chinese patent CN 203264127 U disclosedly a kind ofly reduce pressure, the bivalve DH of voltage stabilizing, this fire hydrant is according to the variation of hydraulic pressure in body, automatically regulate the gap between water inlet end baffle plate and water side baffle plate, thereby realize dynamic voltage stabilizing function, ensure that the hydraulic pressure of delivery port keeps stable within the specific limits.But the decompression of this fire hydrant, stable-pressure device are to be set in exhalant canal, and not only structure is more accurate, complicated, inconvenience is installed, and its seal is also stable, easily there is drainage in long-time use; On the other hand, the fire hydrant of the two outlets of this bivalve can not connect fire hose and fire hose reel simultaneously, if need to connect fire hose reel, need to connect another water pipe from fire-fighting water inlet pipe, and then fire hose reel is connected on this water pipe, inconvenience is not only installed, and has increased installation cost.
Utility model content

The technical solution adopted in the utility model is as follows:
A kind of two outlet of bivalve fire hydrants that can voltage stabilizing, comprise base, valve body, in described base, be provided with intake tunnel, described valve body is arranged on this base and in this valve body and is provided with exhalant canal, on the madial wall of described exhalant canal inner port, form an annular retaining ring, described exhalant canal external port is provided with internal thread; In described exhalant canal, be also provided with into water back-up ring, water outlet back-up ring and the spring between water inlet back-up ring and water outlet back-up ring, described water inlet back-up ring ordinatedly active catch is located on this annular retaining ring, and described water outlet back-up ring screws and is connected with described exhalant canal external port.
Further, the described water inlet back-up ring one side relative with water outlet back-up ring is provided with positive stop lug boss one; The one side that described water outlet back-up ring is relative with water inlet back-up ring is provided with the positive stop lug boss two suitable with described positive stop lug boss one, and the another side of described water outlet back-up ring is provided with an interior angle hole.
Further, the excircle sidewall of described water outlet back-up ring is provided with external screw thread.
Further, described two cover valve bodies are respectively the first valve body and the second valve body, and the exhalant canal external port of this first valve body is provided with one for connecting the hose coupling of fire hose; The exhalant canal external port of described the second valve body is provided with one for connecting the hose connection of fire hose reel.
By above-mentioned known to description of the present utility model, compared to the prior art, the utility model has the advantage of:
1. of the present utility model simple in structure, it is convenient to install, when installation: the back-up ring of intaking successively, spring and water outlet back-up ring are put in exhalant canal, water inlet back-up ring active catch is located on the annular retaining ring in exhalant canal, and can put according to the large freedom in minor affairs adjusted position of actual hydraulic pressure; And water outlet back-up ring can directly screw the water outlet port that is connected to exhalant canal, and water outlet back-up ring is provided with inner hexagonal hole, and person easy to use utilizes instrument that water outlet back-up ring is installed.
