Description
Technical field
The utility model relates to a kind of manually operated valve, relates in particular to a kind of manual asphalt valve.
Background technique
Electrode factory and negative electrode factory high-pressure impregnation workshop in pitch pressure process, because asphalt temperature height, pressure are big, are easy to take place pitch and leak, and have potential safety hazard on the one hand, cause pressure not increase simultaneously, directly influence impregnating effect.And after using after a while, manually asphalt valve need be cleared up inner slag body, and old-fashioned valve bottom and valve body are connected as a single entity, and bring a lot of inconvenience to cleaning.
The model utility content
Technical problem to be solved in the utility model is: a kind of manual asphalt valve is provided, makes valve seal better, Security is higher.
In order to solve the problems of the technologies described above, the utility model is achieved in that a kind of manual asphalt valve, it is to be connected by valve body, handwheel, the apical axis that is connected with handwheel, with the apical axis bottom and the valve plate be located in the valve body constitutes, the upper end of valve body is provided with sealing seat, the stifled post of stuffing box packing and sealing is set between sealing seat and the apical axis, valve inner is provided with valve seat, and valve seat is divided into two chambeies up and down with the valve inner cavity, and described valve plate passes valve seat.
The stifled post of described sealing is located at the top of stuffing box packing.
Be provided with seal ring between described sealing seat and the valve body.
Connect by bolt between described sealing seat and the valve body.
Described valve body is to be made of jacket structured inner valve body and the outer valve of employing, and inner valve body is provided with the pitch gateway, and outer valve is provided with the thermal insulation medium gateway.
Described apical axis is connected by coupling band with valve plate.
Described valve body lower end is provided with closure plate, is provided with seal ring between closure plate and the valve body.
Be connected by bolt between described closure plate and the valve body.
Advantage of the present utility model and effect are as follows:
Since adopted technique scheme, the good airproof performance of the utility model equipment, safe, its Applicable temperature scope is wide, and working medium can be not more than 300 ℃ in temperature, and pressure is not more than proper functioning under the 2.5MPa; Convenient, the easy row of maintenance and cleaning is changed seal ring by dismounting sealing seat and closure plate, the cleaning valve inner.Valve body adopts jacket structured, has effectively prevented the working medium cooling.
