Abstract
The utility model discloses a kind of engine valve device, comprise valve and valve seat, valve is divided into bar portion and tapering, valve seat center is valve port, the bar portion of valve inserts this valve port, and described valve seat outer surface is provided with the screw thread coordinating with cylinder head, and valve seat upper end is six side adjustable sides, on six side adjustable sides, be combined with successively valve spring, pad and jump ring, valve seat lower end is the open end of supporting valve tapering; On the inwall of described valve port, offer spiral chute.The utility model engine valve device is convenient to maintenance and is made engine gas more thorough.
Description
Technical field
the utility model belongs to the special throttle valve field of combustion engine.
Background technique
the effect of valve (Valve) is to be responsible for specially in motor to input fuel combustion gas, and valve is responsible for pressing off by cam, and valve spring is responsible for closing.In the time that needs suck mixed gas and enter cylinder, intake valve just can be opened; In the time that needs are got rid of the waste gas after burning, exhaust valve just can be opened.
the solar term gate seat of motor is all in the time of casting cylinder cover, to cast out valve seat at present, then processes finishing with machinery, and facing-up valve.In use for some time, valve gear there will be following problem to motor: (1) due to valve seat in engine cylinder cap inside be do dead, so just can place under repair after valve or valve seat generation problem all will be pulled down engine cylinder cap; (2) because inside and outside air valve seat ring inwall is even surface, valve can only be done point-to-point moving up and down therein, thereby cause the valve face of valve and air valve seat ring very easily to produce uneven wear, greatly shortened valve and air valve seat ring working life, meanwhile, valve moves up and down in level and smooth air valve seat ring inwall, also can only produce straight moving air flow, this air-flow makes oil gas degree of mixing poor, and air feed relative quantity deficiency in addition has directly affected the firing effect of power and the fuel of internal-combustion engine.
Model utility content
the utility model is intended to provide a kind of fast engine valve device of adjusting, maintenance and airspeed of being convenient to.
the purpose of this utility model can reach by following measures: engine valve device, comprise valve and valve seat, valve is divided into bar portion and tapering, valve seat center is valve port, the bar portion of valve inserts this valve port, it is characterized in that: described valve seat outer surface is provided with the screw thread coordinating with cylinder head, and valve seat upper end is six side adjustable sides, on six side adjustable sides, be combined with successively valve spring, pad and jump ring, valve seat lower end is the open end of supporting valve tapering; On the inwall of described valve port, offer spiral chute.
technique scheme difference with the prior art is: valve seat is provided with the screw thread coordinating with cylinder head, make valve gear maintenance, check and regulate time without unloading whole cylinder head, just can directly regulate valve, in addition, because valve port inwall has spiral chute, while making gas through valve port, can form spiral air flow, make inlet and outlet more abundant, air-fuel mixture is more even, and burning more fully thoroughly.
further, described spiral fluted cross section is V-arrangement or U-shaped, has reduced groove difficulty of processing.
further, valve seat is powder metallurgy valve seat, and intensity is higher, more wear-resistant.
Brief description of the drawings
below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
fig. 1 is the utility model engine valve device embodiment 1 structural representation;
fig. 2 is the structural representation of valve seat in Fig. 1.
Embodiment
embodiment 1: as shown in Figure 1 and Figure 2, engine valve device, comprises the valve seat 2 that valve 1 and powder metallurgy are made, and valve 1 is divided into bar portion and tapering, and valve seat 2 centers are valve port 3, and the bar portion of valve 1 inserts this valve port 3 and coordinates with valve seat 2.Valve seat 2 outer surfaces are threaded 4, and valve seat 2 is threaded with cylinder head.Valve seat 2 upper ends are six side adjustable sides, use spanner to pull six side adjustable sides and can regulate or dismantle valve seat 2.Valve seat 2 lower ends are the open end of supporting valve 1 tapering, and valve seat is combined with valve spring, pad and jump ring on 2 six side adjustable sides successively, and valve 1 can be automatically replied.On the inwall of valve port 3, have spiral chute 5, the cross section of this spiral chute 5 is V-arrangement.
embodiment 2: be that with embodiment 2 difference spiral fluted cross section is U-shaped.
the foregoing is only the detailed description of the utility model preferred embodiment, be not used for limiting the utility model, the embodiment of all similar variations of doing according to creation spirit of the present utility model, all should be contained among the utility model protection domain.
Claims (3)
1. engine valve device, comprise valve and valve seat, valve is divided into bar portion and tapering, valve seat center is valve port, the bar portion of valve inserts this valve port, it is characterized in that: described valve seat outer surface is provided with the screw thread coordinating with cylinder head, and valve seat upper end is six side adjustable sides, on six side adjustable sides, be combined with successively valve spring, pad and jump ring, valve seat lower end is the open end of supporting valve tapering; On the inwall of described valve port, offer spiral chute.
2. engine valve device according to claim 1, is characterized in that: described spiral fluted cross section is V-arrangement or U-shaped.
3. engine valve device according to claim 1, is characterized in that: described valve seat is powder metallurgy valve seat.
