Abstract
The utility model discloses a three-way reversing valve which comprises a valve body. The valve body is divided into a cavity A, a cavity B and a cavity C through valve plate bases, and the three cavities are communicated with the external. Valve plates are arranged between the cavities, the valve plates are connected with an air cylinder, the matching surfaces of the valve plates and the valve plate bases are provided with annular grooves and annular bosses, and soft sealing rings are embedded into the grooves. The three-way reversing valve is good in sealing effect and long in service life.
Description
Technical field
The utility model relates to a kind of for the device on industrial combustion furnace control burner, particularly a kind of three-way diverter valve.
Background technique
In industrial combustion furnace system, in order to control the flow direction of combustion gas, generally can adopt selector valve, play the effect of opening and closing combustion gas.Three-way diverter valve is mainly made up of parts such as valve body, valve plate seat, valve plate and cylinders, drives valve plate to move by cylinder, thereby changes the flow direction of gas in pipeline.Because be carries out work in higher temperature gas, main action is to make fuel gas, air enter stove burner and waste gas eliminating, and the two is circulation alternately, and gas exchange is carried out in timing, therefore the action of valve is more frequent, and the seal request between valve plate and valve plate seat is quite strict.
The sealing of existing valve plate and valve plate seat is mainly divided into soft seal and two kinds of situations of hard sealing, soft seal has good sealing effect, but working life is short and non-refractory, hard sealing can be high temperature resistant, but sealing effect is undesirable, leakage rate is large, therefore takes merely the valve plate of these two kinds of seal form can not meet on-the-spot requirement in the time that reality is used.
Model utility content
For solving the problems of the technologies described above, the utility model provides a kind of three-way diverter valve, can improve sealing effect to reach, and the object that can increase the service life.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of three-way diverter valve, comprise valve body, described valve body is divided into three cavity A, B, C that communicate with the external world by valve plate seat, between cavity, be provided with valve plate, described valve plate is connected with cylinder, the fitting surface place of described valve plate and valve plate seat is provided with annular groove and annular boss, and described inside grooves is embedded with soft seal ring.
Preferably, described three cavitys are respectively equipped with gas-air mouth, exhaust outlet and fuel burner nozzle mouth.
Pass through technique scheme, the three-way diverter valve that the utility model provides is by the combination of annular groove and annular boss, be conducive to moving into place of valve plate, groove is embedded with soft seal ring, can prevent the damage that excessive compression causes, can make pressing more tight, play dual sealing functions.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below.
Fig. 1 is the structural representation of the disclosed a kind of three-way diverter valve of the utility model embodiment;
Fig. 2 is the enlarged diagram of D part in Fig. 1.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described.
The utility model provides a kind of three-way diverter valve, structure as shown in Figure 1, this three-way diverter valve good sealing effect, and long service life.
Three-way diverter valve as shown in Figure 1, comprise valve body, valve body is divided into three cavity A, B, C that communicate with the external world by valve plate seat 3, between cavity, be provided with valve plate 1, valve plate 1 is connected with cylinder 2, with reference to figure 2, valve plate 1 is provided with annular groove 4 and annular boss 5 with the fitting surface place of valve plate seat 3, and groove 4 inside are embedded with soft seal ring 6.
Three cavitys are respectively equipped with gas-air mouth 7, exhaust outlet 8 and fuel burner nozzle mouth 9, control valve plate 1 and move to the left side of valve plate seat 3 when cylinder 2, and when sealing contact, exhaust outlet 8 communicates with fuel burner nozzle mouth 9; Control valve plate 1 and move to the right side of valve plate seat 3 when cylinder 2, when sealing contact, gas-air mouth 7 communicates with fuel burner nozzle mouth 9.
The three-way diverter valve that the utility model provides, by the combination of annular groove and annular boss, is conducive to moving into place of valve plate, and groove is embedded with soft seal ring, can prevent the damage that excessive compression causes, can make pressing more tight, play dual sealing functions, and commutating speed be fast.
To the above-mentioned explanation of the disclosed embodiments, make professional and technical personnel in the field can realize or use the utility model.To be apparent for those skilled in the art to these embodiments' multiple modification, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
