Abstract
The utility model relates to a clamp type plate valve comprising a valve body, a valve rod, and a valve cap, which is characterized in that: a gland cover is arranged inside the through hole of the valve body; a check ring is respectively arranged at the two sides of the gland cover; a valve plate is arranged inside the valve body; the upper end of the valve plate is connected with the valve rod through a conical pin; the valve cap is arranged at the upper part of the valve body; the valve rod is arranged inside the valve cap; a seal packing ring is arranged between the valve cap and the valve rod; a gland bush is arranged on the seal packing ring; the gland bush and the seal packing ring is connected with each through a screw bolt; a hand operated mechanism is arranged on the valve cap through a nut; a locknut locks and fastens the hand operated mechanism. The utility model has the advantages in that: 1. Low costs, simple work art and high sensitivity. 2. A gland bush is arranged already, no need of adding an outer gland bush, facilitating convenience for installation. The upper medium of the valve plate exerts a face seal under force effect; the middle and lower part of the valve plate exert a brake locking seal downwards. 3. The sealing structure is reasonable, can normally handle sealing without no need of strong force effect while closing. 4. Long life expectancy, and no eddy current inside the inner cavity. 5. A clamp type plate valve can be installed onto a pipeline system with water, vapor, sewage or much impurity.
Description
Technical field; The utility model relates to a kind of wafer type plate valve that is applicable to water, steam and sewage.
Background technique: it is big that the similar valve of prior art exists the gate valve volume, and sealing part is mingled with shortcomings such as matter influence sealing, operation heaviness easily.
Summary of the invention: the purpose of this utility model is at above-mentioned the deficiencies in the prior art, is improved on the basis of plate valve and Wedge gate valve internal structure, the wafer type plate valve that the cost of production of design is low, performance good, the life-span is long.Its concrete technological scheme is: the wafer type plate valve, comprise valve body, valve rod, valve gap, valve gap is connected by bolt with valve body, stuffing box gland is installed in the valve hole, on its both sides back-up ring is installed, valve plate is installed in the valve body, the upper end of valve plate is connected with valve rod by taper pin, valve gap is installed in the top of valve body, and valve rod is installed in the valve gap, and the stuffing box packing ring is installed between valve gap and valve rod, stuffing box packing ring gland is installed on the stuffing box packing ring, and by bolt and nut connection, man-operated mechanism is installed on the valve gap by nut, back of the body cap locking man-operated mechanism.
The utlity model has following performance and characteristics: 1, operating cost is low, in light weight, technology simple, it is highly sensitive to use.When 2, installing, self has flange gasket, need not add sealing gasket, and easy for installation.Valve plate top is that face seal is leaned in the stressed back of medium, the downward lock sealing in valve plate middle and lower part.3, sealing configuration is reasonable, need not be stressed excessive when closing, and stressed less with the relatively more same specification of Wedge gate valve, and can normally seal.4, compare long service life with other gate valves, inner chamber does not have eddy current.5, the wafer type plate valve can be installed on the more pipeline of water, steam, sewage, impurity and use.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the right elevation of Fig. 1.
Embodiment:
With reference to Fig. 1,2, the wafer type plate valve, comprise valve body 4, valve rod 15, valve gap 8, valve gap 8 is connected by bolt 5 with valve body 4, it is characterized in that: stuffing box gland 3 is installed in valve body 4 through holes, on its both sides back-up ring 2 is installed, valve plate 1 is installed in the valve body 4, and the upper end of valve plate 1 is connected with valve rod 15 by taper pin 6, and valve gap 8 is installed in the top of valve body 4, valve rod 15 is installed in the valve gap 8, stuffing box packing ring 7 is installed between valve gap 8 and valve rod 15, stuffing box packing ring gland 10 is installed on stuffing box packing ring 7, and connect by bolt 9 and nut 11, man-operated mechanism 13 is installed on the valve gap 8 by nut 12, back of the body cap 14 locking man-operated mechanisms 13.
