Description

Technical Field

[0001] The present invention relates to the technical field of fire-fighting equipment, and particularly to a production process of a fire pump adapter. Background Art

[0002] A pump adapter is a device used in combination with a pump in fire-fighting. It is usually used in combination with a flange pipe, an elbow, a check valve, a drain valve, and a gate valve to ensure the normal operation of the indoor pipe network. When a fire occurs, the pump of a fire truck can quickly and conveniently connect to the fire-fighting equipment in a building through the fire-fighting interface of the pump adapter and supply water under pressure, so that the fire-fighting equipment indoors can obtain sufficient pressurized water sources to extinguish fires on different floors, effectively solving the problems that it is difficult for a fire truck to extinguish a fire after a fire occurs in a building or the fire-fighting equipment indoors cannot extinguish a fire due to lack of sufficient pressurized water sources. However, the fire-fighting interfaces on the existing pump adapters in the market are made of copper materials and are easily stolen. Summary of the Invention

[0003] Therefore, in view of the above problems, the present invention proposes a production process of a fire pump adapter to solve the problem of theft of the fire-fighting interface on the pump adapter.

[0004] To achieve the above object, the present invention adopts the following technical solutions: A production process of a fire pump adapter includes the following steps:

[0005] a. Prepare the adapter body: including a cast adapter blank, which is heat-treated and cooled to form an adapter blank with more than one water outlet pipe, and the inner and outer surfaces of the obtained adapter blank are polished, anti-corrosion treated, and waterproof treated to obtain the adapter body. The outer surface of the end of the water outlet pipe of the obtained adapter body has a fixing ring, and the inner surface has an internal thread. The fixing ring is provided with a plurality of through holes along its axial direction;

[0006] b. Prepare the fire-fighting interface:

[0007] b1. Take a metal plate for cutting, stamping, bending, and welding to obtain an interface blank. The obtained interface blank has a cylinder blank. The outer surface of one end of the cylinder blank has a connection ring blank, and a plurality of fixing rod blanks are provided on the connection ring blank;

[0008] b2. Treat the inner and outer surfaces of the obtained interface blank with hand-laid fiberglass resin material, and after drying and polishing, obtain the fire-fighting interface. The obtained fire-fighting interface has a cylinder, a connection ring, and fixing rods. The outer surface of the other end of the cylinder without a connection ring is provided with an external thread;

[0009] c. Prepare the fixing pin;

[0010] d. Assemble the fire pump adapter: Insert the valve core and valve stem for controlling the fluid into the adapter body obtained in step a. Insert the fixing rod of the fire protection interface obtained in step b into the through hole of the fixing ring, and screw the external thread of the fire protection interface tightly with the internal thread of the water outlet pipe. Then insert the fixing pin into the through hole and have an interference fit with the through hole provided with the fixing rod.

[0011] Further improvement: In the above step a, a relief groove is further provided on the side of the fixing ring of the water outlet pipe facing the adapter body, and the relief groove communicates with the through hole. In the above step b2, an end portion of the fixing rod blank further has a clamping block blank, and the clamping block blank forms a clamping block after hand lay-up post-treatment. When the fire protection interface is screwed tightly with the water outlet pipe, the clamping block is clamped into the relief groove.

[0012] Further improvement: In step d, after the fixing pin is inserted, a filler is filled into the through hole and the relief groove, and the filler is a glass fiber resin material.

[0013] Further improvement: A filling piece for filling the gap between the connecting ring and the fixing ring is provided between the connecting ring and the fixing ring.

[0014] Further improvement: It further includes step e, preparing a plug:

[0015] e1. Take a metal plate for cutting and stamping to obtain a plug blank;

[0016] e2. Perform hand lay-up glass fiber resin material treatment on the inner and outer surfaces of the obtained plug blank, and obtain a plug after drying and grinding. The obtained plug is used to block the fire protection interface.

[0017] By adopting the foregoing technical solutions, the beneficial effects of the present invention are as follows: The present technical solution specifically designs a protection and anti-theft structure for the fire protection interface of the fire pump adapter. During the production process, the fire protection interface uses a metal blank and is then treated by hand lay-up glass fiber resin material to meet the requirements of structural installation firmness and protection, making the fire protection interface not easily damaged. Compared with the traditional metal fire protection interface structure, it is lighter in weight, not only easy to form, but also has high production accuracy compared with the metal casting process, thus facilitating assembly and transportation and reducing the subsequent processing steps; the same is true for the structure setting of its plug;

[0018] When the fire protection interface of the present invention is installed, on the basis of the spiral connection between the water outlet pipe and the fire protection interface, a fixed structure is cooperated to form a stable mortise and tenon structure between the fixing ring and the connecting ring. The entire fixed structure does not have common disassembly and assembly structural parts such as screws on the outer surface. By inserting the fixing pin, not only can the connection between the fire protection interface and the water outlet pipe be tightened, but also it cannot be knocked out by external force, thereby improving the anti-theft performance of the fire protection interface;

[0019] After the fire-fighting interface is installed, through the settings of the packing and the filling sheet, the outer surfaces of the connecting ring and the fixing ring are combined to form a flat surface, which is beautiful in appearance. Brief Description of the Drawings

[0035] And this technical solution is obtained on the basis that the fire fighting interface is made of fiberglass. Specifically:

[0036] A production process of a fire pump adapter includes the following steps:

[0037] a. Prepare the adapter body 100: including a cast adapter embryo, which is heat-treated and cooled to form an adapter embryo with more than one water outlet pipe 1.
