Abstract
The utility model discloses a soft sealing locked internal-thread connecting gate valve, comprising a valve body (1) and a gate plate (2) positioned in the valve body (1), wherein a valve cover (5) matched with the valve body (1) is arranged above the valve body (1) and is internally provided with a valve rod (3); and one end of the valve rod (3) is connected with the gate plate (2). The soft sealing locked internal-thread connecting gate valve is characterized in that the gate plate (2) comprises a skeleton and a soft sealing gate valve wrapped on the skeleton and made of rubber; and a water inlet and a water outlet of the valve body (1) are provided with internal threads and are in threaded connection with pipelines. The soft sealing locked internal-thread connecting gate valve has the advantages that the closing performance is good, the use cost is low, no pressing cover is used for sealing the valve cover, the maintenance cost is low and the opening and closing reliability is high.
Description
Technical field
The utility model relates to soft sealing gate valve, especially a kind of soft sealing gate valve with lock that is threaded.
Background technique
Gate valve is widely used in the productive life field.Gate valve generally comprises valve body and valve plate, and existing valve body two ends are typically provided with flange, realize by flange when being connected with pipeline.Simultaneously existing gate valve is hard seal gate valve, because the valve body fluid passage of hard seal gate valve is provided with the groove suitable with valve plate, when adamant such as sand was arranged in the fluid, can be trapped in influenced closing of gate valve in the groove.The gate valve two ends are connected with the flange that is connected to of pipeline, and installation and dismounting workload are big, processing and user cost height.The sealing on the valve gap top of existing gate valve is to seal by gland and the valve gap scyewed joint upper end portion to valve gap, because scyewed joint is subject to the influence of external environment condition, needs frequent maintenance, has increased maintenance workload.Existing gate valve is installed in the field of employment, and switch just can be opened easily without any protection work, and its actual switch state is subject to extraneous factor influence, switch poor reliability concerning the user.
The model utility content
The purpose of this utility model solves existing gate valve exactly, and to close performance bad, and maintenance workload is big, the user cost height, and on off state is subject to external environment influence, the problem of switch poor reliability.
The technical solution adopted in the utility model is: soft seal internal thread with lock connects gate valve, it comprises valve body and is positioned at the flashboard of valve body, the top of valve body is provided with the valve gap that cooperates with it, be provided with valve rod in the valve gap, valve rod one end is connected with flashboard, it is characterized in that described flashboard comprises that skeleton and the rubber that is wrapped on the skeleton constitute soft sealing gate valve, the water intake and the water outlet of described valve body are provided with internal thread, are connected to pipeline to be threaded.
Adopt technique scheme, because gate valve is a soft sealing gate valve, no longer be provided with groove in the valve body, feasible impurity by the gate valve medium can not deposit, and does not close thereby do not influence, and improves and closes performance.Because the utility model adopts two ends scyewed joint pipeline, fast convenient, reduced user cost.
For reducing maintenance cost, it is characterized in that in the described valve gap from up to down being two shoulder holes that increase successively, being provided with seal ring between the valve rod of upper shoulder hole and the hole wall seals body cavity, be provided with locking cap between the hole wall of middle shoulder hole and the valve rod with the hole wall scyewed joint, valve rod is provided with annular boss above locking cap, stop valve rod to move down by locking cap extruding annular boss.Adopt such scheme, valve rod is positioned in the step hole, no longer need seal pressure with union (screwed)bonnet (UB above valve gap, has saved maintenance, has saved cost.
For increasing switch reliability of the present utility model, the top of described valve gap is provided with the pipe box that is connected as a single entity with valve gap, pipe box is stretched on valve rod top, the top is lower than the top of pipe box, valve rod top is multi-faceted column, top is provided with the key that matches with valve rod top, described key comprise minor axis with the vertical handle that links to each other of minor axis, the minor axis end is provided with the multiaspect cylindrical bore adaptive with valve rod.Adopt such scheme, when gate valve is installed in the uppity environment, take away key, valve rod has the pipe box protection, is difficult for contact, and does not have special tool, can not open, and has increased the reliability of gate valve switch greatly.
In sum, the utility model beneficial effect is: because the utility model adopts soft seal, it is good to close performance, adopts screw thread to be connected with pipeline, and user cost is low, does not have the gland seal valve gap, and maintenance cost is low, is provided with key, makes the reliability height of switch.
