Abstract
The utility model belongs to the field of gas engines, and particularly relates to a high temperature resistance safety valve. The high temperature resistance safety valve comprises a valve seat, a valve clack, a bottom plate, a top plate, a spring and a guide mechanism, wherein the valve seat, the valve clack, the bottom plate and the top plate are arranged in sequence from bottom to top; the valve clack and the valve seat are in conical sealing; the bottom plate is fixed on the valve clack through a bolt in a parallel mode, and a gap is reserved between the bottom plate and the valve clack; the top plate is fixedly connected with the valve seat through a screw rod; the spring is arranged between the bottom plate and the top plate, and the two ends of the spring are fixed at the bottom plate and the top plate respectively; the guide mechanism comprises a guide pin and a guide plate which is in clearance fit with the guide pin, wherein the guide pin is in rigid connection with the valve seat in an interference fit mode, and the guide plate is in rigid connection with the valve clack. The high temperature resistance safety valve can solve the problems that an existing safety valve is complex in structure, high in cost and poor in leakproofness, and has the advantages of being good in high temperature resistance effect, simple in structure, low in cost, and good in leakproofness, thereby being suitable for the gas engines.
Description
Technical field
The utility model belongs to the gas engine field, particularly a kind of heat temperature resistant safe valve.
Background technique
In the outlet pipe of gas engine, for preventing the outlet pipe tempering, blast, affect the normal use of pressurized machine and baffler, so need to the safety valve that can be operated under high temperature condition be installed on outlet pipe.Lever and weight loaded safety valve is better to the tolerance of high temperature, is to use at present maximum a kind of safety valves.This safety valve need adopt weight and lever construction, so its structure is more complicated, and cost is higher.And it exists a maximum defect to be exactly, and its poor sealing, be mainly the impact of easily being vibrated due to its load maintainer, and usually therefore produces and reveal; Add that its Reseating pressure of a safety valve is lower, after unlatching, be difficult for closing and keep tight, therefore the sealing of palpus confirmation and regulating valve after unlatching, bring difficulty to the motor rapid re-strike.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of heat temperature resistant safe valve; This safety valve is when high temperature tolerance and sealing are protected, simple in structure and cost is low.
In order to solve the problems of the technologies described above, the utility model provides following technological scheme:
A kind of heat temperature resistant safe valve, comprise the valve seat set gradually from down to up;
One flap, form conical surface seal with valve seat;
One base plate, be fixed on flap by bolt is parallel, and and flap between leave gap;
One top board, described top board is fixedly connected with valve seat by screw rod;
Between described base plate and top board, be provided with spring, its two ends are individually fixed in base plate and top board;
Also comprise a guide mechanism, comprise guide finger and with its Spielpassung guide plate; Described guide finger is rigidly connected by interference fit and valve seat; Described guide plate and flap are rigidly connected.
The utlity model has following beneficial effect: 1. safety valve high-temperature resistant result of the present utility model is good: between flap and base plate, leave certain gap, can reduce the heat transmission of flap and spring bottom plate, and can strengthen the heat dissipation potential of spring bottom plate, thereby reduced the temperature of spring bottom plate, guaranteed the normal operation of safety valve spring;
2. safety valve structure of the present utility model is simple, cost is low: agent structure is that finished product plate or the pipe fitting blanking of employing standard processes, and the precision-fit of demand is partly few, processing technology is required simple, and most of structure (as spring, guide finger etc.) is all to use standard piece, further reduces costs;
3. safety valve good airproof performance of the present utility model: flap and valve seat form conical surface seal, and this sealing is not subject to the impact shaken, good sealing effect; Be provided with simultaneously guide mechanism, guarantee that flap returns in unlatching the precision that seat is put afterwards.
Further, described spring overcoat is connected to guide pipe.
Guide pipe is protected spring for limiting maximum compressibility, and can further help flap and return afterwards in unlatching the precision that seat is put.
Further, this heat temperature resistant safe valve also comprises the case that is fixed in valve seat, and described flap, base plate, spring, top board and guide mechanism are positioned at case; Described case is provided with vent.
Case can play to the vitals of valve body certain protective action.
Further, described case comprises side plate and the cover plate be connected with side plate, and described cover plate is conical.
On rainy day, conical cover plate can will disperse and flow to ground in the fastest time, prevents that rainwater from entering in case.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, technical solution of the present invention is further illustrated:
Fig. 1 is the sectional view of heat temperature resistant safe valve flap of the present utility model while opening;
Wherein the direction of arrow is airflow direction.
Embodiment
As shown in Figure 1, a kind of heat temperature resistant safe valve, comprise the valve seat 1 set gradually from down to up; One flap 2, the sealing pair formed with valve seat 1 is conical surface seal; One base plate 3, be fixed on flap 2 by bolt is parallel, and have gap with flap 2; One top board 4, described top board 4 is fixedly connected with valve seat 1 by screw rod; Between described base plate 3 and top board 4, be provided with spring 5, its two ends are individually fixed in base plate 3 and top board 4; The outer guide pipe 7 that is socketed with of described spring 5.Described heat temperature resistant safe valve also comprises a guide mechanism, comprise guide finger 8 and guide plate 9, guide plate 9 is provided with the through hole of bar shaped, an end of guide finger 8 pass this through hole and with guide plate 9 Spielpassung, guide finger 8 is rigidly connected by interference fit and valve seat 1, makes bar hole become vertical with base; Guide plate 9 the other ends and flap 2 are rigidly connected; Strip through-hole has limited the movement locus of guide plate 9, thereby has indirectly limited the movement locus of flap 2, has guaranteed that flap 2 returns in unlatching the precision that seat is put afterwards;
This heat temperature resistant safe valve also comprises the case that is fixed in valve seat 1; Described case comprises side plate 10 and the cover plate 11 be connected with side plate 10, and described cover plate 11 is conical, and this cover plate 11 is similar to the design of pitched roof, prevents that rainwater from entering in case.
In use, when the pressure increase in outlet pipe reaches the preload pressure of safety valve spring 5, spring is by compressed, to such an extent as to the flap assembly that flap 2 and base plate 3 form is away from upwards running of valve seat 1, thereby open valve, pressurized gas in outlet pipe are released, the gas pressure in the balance row tracheae.After pressurized gas were discharged, outlet pipe pressure sharply descended, now, the flap assembly that flap 2 and base plate 3 forms steadily falls after rise under the leading role of the pressure-acting of spring 5 and guiding device, again reach sealing effect, and then in the short period of time, motor can open machine work again again.
Above-described is only preferred implementation of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
