Abstract
The utility model relates to a protection device in industry field especially relates to a flange bolt prevents protection device that collapses, including fluid end assembly, high -pressure outlet(discharge) flange the junction of flange and fluid end assembly install two taper pins at least, the taper pin is at junction symmetrical arrangement, and it has a flange bolt safety cover to be close to high -pressure outlet(discharge) flange outer end fixed mounting, flange bolt safety cover and fluid end assembly fixed connection. Adopt this kind of structure to stabilize more being connected of high -pressure outlet(discharge) flange and fluid end assembly, prevent effectively that flange connecting bolt is not hard up, reduce the impaired and fracture of bolt, and under the condition that connecting bolt became invalid the safety of the guarantee person and equipment.
Description
Technical field
This utility model relates to a kind of equipment of industrial product technical field, particularly relates to the protection device that a kind of flange bolt is prevented collapsing.
Background technology
In the industry, a lot of job sites need pump truck feed flow, all can use Flange joint between common pump truck fluid end assembly and pipeline, and high-pressure outlet flange surrounding is fixed on fluid end assembly by bolt, nut with spring washer.Fluid end is in use, pump truck is when feed flow is interrupted, owing to pipeline vibration amplitude increases, asynchronous with pump vibrations, high-pressure outlet flange bolt is formed shearing force, thus it is impaired to cause connecting bolt to loosen, even rupture, the bolt of fracture, nut fly out at a high speed, and personal safety and equipment to operator cause safely threat greatly, there is serious potential safety hazard.
Summary of the invention
When the purpose of this utility model is to avoid pump truck feed flow process interrupted, flange bolt loosens to fly out and brings personal safety to staff; and provide the protection device that a kind of flange bolt is prevented collapsing; this utility model more consolidates the structure of flange and bolt, and staff and equipment are served protective effect.
The novel purpose of this use is achieved by the following measures: the protection device collapsed prevented by a kind of flange bolt; including fluid end assembly, high-pressure outlet flange; in the junction of described flange Yu fluid end assembly, two taper pins are at least installed; described taper pin is arranged symmetrically with in junction; next-door neighbour high-pressure outlet flange outer end is installed with flange bolt protective cover, and described flange bolt protective cover is fixing with fluid end assembly to be connected.
Preferably, described taper pin is two, is separately mounted to the symmetric position of high-pressure outlet flange and both sides, fluid end assembly junction.
Preferably, described flange bolt protective cover is connected by steel wire rope is fixing with fluid end assembly.
Preferably, being respectively arranged with annulus at described steel wire rope two ends, annulus is fixedly connected with bolt, described steel wire rope one end is bolted at fluid end assembly, and the other end is bolted on flange bolt protective cover.
Preferably, in described high-pressure outlet flange and fluid end assembly junction surrounding by 1 "-8 tooth bolts, nut be tightly fastened with spring washer.
Preferably, described bolt is 1 cun of stud.
The beneficial effects of the utility model: flange is tightly fastened with fluid end assembly by this utility model by taper pin, more consolidate the structure of flange and bolt, and the danger that flange bolt protective cover blocks the bolt of inefficacy, nut flies out protects personal safety.The steel wire rope being connected between flange bolt protective cover with fluid end assembly also plays drag effect, and when bolt failure, steel wire rope tightly hauls flange bolt protective cover and is allowed to be difficult to fly out or fall.Prevent that collapsing protection device all serves protective effect to staff or equipment for this kind.

Detailed description of the invention
In order to deepen understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail.
Embodiment one
nullSuch as Fig. 1、2、3、4、Shown in 5，The protection device collapsed prevented by flange bolt，Including fluid end assembly 1、High-pressure outlet flange 4，High-pressure outlet flange 4 passes through 1 with fluid end assembly 1 junction surrounding "-8 tooth bolts 8、Nut 6 fixedly mounts with spring washer 7，High-pressure outlet flange 4 is at least provided with two taper pins with the symmetric position of both sides, fluid end assembly 1 junction，Its taper pin can bear the shearing force of more than 15 tons，Next-door neighbour high-pressure outlet flange 4 outer end is installed with flange bolt protective cover 3，Flange bolt protective cover 3 both sides are tightly fastened in high-pressure outlet flange by bolt，And surrounding is close to flange，It is connected between flange bolt protective cover 3 with fluid end assembly 1 and has steel wire rope，Steel wire rope is respectively arranged at two ends with annulus，Bolt it is fixedly connected with on annulus，Steel wire rope one end is bolted at fluid end assembly 9，The other end is bolted at the 5 of flange bolt protective cover.
By above-mentioned protective measure, showing through 155MPa high water pressure test, such as Fig. 6 pressure-time curve figure, can be greatly increased the tensile strength of bolt, minimizing bolt is impaired and ruptures, and ensures the safety of the person and equipment in the case of connecting bolt lost efficacy.
