Description
Technical Field
The utility model belongs to the technical field of the fire-fighting equipment and specifically relates to an automatic on-off valve of fire control is related to.
Background
In recent years, along with people's the gradual attention to fire control equipment, fire control safety also becomes the important thing in the life, but there are many remote or unmanned on duty regions, there is the potential safety hazard of difficult discovery or dredging the management, in the comparatively narrow and small equipment in some space or region, because space restriction, can't set up conventional fire equipment, when taking place the condition of a fire, can't in time discover in earlier stage, when developing into great ignition point, great loss has been caused, and it is very difficult when putting out a fire, consequently need to set up a fire control valve that can automatic start and close in this type of region, can just be used in the earlier stage of the conflagration, and put out initial conflagration.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a fire control automatic on-off valve solves unmanned on duty's place and piles up the problem of the automatic fire extinguishing who easily fires the rubbish and stack the department.
In order to achieve the technical purpose, the utility model adopts the following technical scheme.
An automatic fire-fighting opening and closing valve comprises a valve body, wherein a through hole is formed in the valve body, the valve body is connected with an outer cover through a valve cover, a valve rod is arranged in an inner cavity of the outer cover, the valve rod vertically penetrates through the valve cover, the lower end of the valve rod penetrates through the through hole in the valve body, a positioning sleeve is arranged at the upper part of the valve rod, and a valve clack is arranged at the lower end of; the method is characterized in that: a spring is not arranged between the positioning sleeve and the valve cover, a common spring and a memory spring are arranged between the upper surface of the positioning sleeve and the top of the outer cover, and the common spring is sleeved in the memory spring and is in a stretched state.
Further, a rubber sealing ring is arranged between the valve rod and the valve cover.
Further, the valve cover is in threaded connection with the valve body and the outer cover.
Further, the cross section of the valve clack is hexagonal.
Further, the valve clack is made of rubber.
The utility model has the advantages that: the memory alloy is used, so that the valve can be automatically opened and closed; and the memory spring and the common spring are sleeved together, so that the size of the valve can be effectively reduced, and the valve can be arranged in a narrow space.

Fig. 1 is a schematic structural diagram of the present invention.
Reference numerals: 1-valve body, 2-valve clack, 3-valve rod, 4-rubber seal, 5-valve cover, 6-locating sleeve, 7-common spring, 8-memory spring, 9-housing.
Detailed Description
Hereinafter, the embodiment of the automatic fire-fighting on-off valve of the present invention will be described with reference to the attached drawings.
The drawings attached to the present specification are for illustrative purposes, and are used to schematically show the shapes of various parts and their relationships to each other, and the same reference numerals are used to denote the same parts.
As shown in fig. 1, the automatic fire-fighting opening and closing valve comprises a valve body 1, wherein a through hole is formed in the valve body 1, the valve body 1 is connected with an outer cover 9 through a valve cover 5, a valve rod 3 is arranged in an inner cavity of the outer cover 9, the valve rod 3 vertically penetrates through the valve cover 5, the lower end of the valve rod 3 penetrates through the through hole in the valve body 1, a positioning sleeve 6 is arranged at the upper part of the valve rod 3, and a valve clack 2 is arranged at the lower; the method is characterized in that: a spring is not arranged between the positioning sleeve 6 and the valve cover 5, a common spring 7 and a memory spring 8 are arranged between the upper surface of the positioning sleeve 6 and the top of the outer cover 9, and the common spring 7 is sleeved in the memory spring 8 and is in a stretched state. Ordinary spring 7 and memory spring 8 cover together, can effectively reduce the valve volume, have better practicality to some equipment or regional that the space is narrow and small.
As shown in fig. 1, a rubber seal 4 is provided between the valve stem 3 and the bonnet 5.
In this embodiment, through threaded connection between valve gap 5 and valve body 1 and the dustcoat 9, threaded connection has reliable and stable advantage, and the installation is simple and convenient, and when the valve volume is less, the screw thread is makeed more easily, reduce cost. The valve cover 5 can be connected with the valve body 1 and the outer cover 9 through clamping and pressing, and the valve is convenient and fast to use.
In this embodiment, the shape of the cross section of the valve flap 2 is hexagonal, the valve flap 2 can also be trapezoidal, oval and the like, the valve flap 2 is made of rubber, soft materials can be better attached to the valve port, the sealing effect is better, and the rubber has better corrosion resistance.
In the embodiment, the valve body 1 has a straight-through type and a right-angle type, and adopts different shapes according to different use conditions, so that different requirements are met.
The function principle of the utility model is explained by combining with figure 1, under the normal temperature condition, the memory spring is in the free state, the common spring is in the stretching state, the valve rod is stressed to drive the valve clack to close the valve port; when the external temperature changes and rises to the critical temperature, the memory spring is in an extension state, overcomes the pulling force of a common spring, pushes the valve rod to open the valve port, and leads water to circulate to carry out fire extinguishing work; after the temperature is reduced to the critical temperature, the memory spring is restored to the free state, the valve rod is driven by the pulling force of the common spring, and the valve port is closed.
The utility model discloses with memory spring and ordinary spring suit together, the effectual volume that reduces the valve body can be used in comparatively strict region and equipment to the space requirement.
The embodiments described in this specification are merely illustrative of implementations of the inventive concept and the scope of the invention should not be considered limited to the specific embodiments described in the examples, but rather based on the technical equivalents thereof which can be conceived by those skilled in the art based on the inventive concept.
