Abstract
The utility model provides a fouling eliminating and good sealing cone core stop valve, comprising a valve seat, a valve rod, a valve core and a valve bonnet. The valve seat is provided with a water inlet and a water outlet. The through position of the water inlet and the water outlet which is inside the valve seat is provided with a sealing lip. The valve core is arranged inside the sealing lip. The utility model is characterized in that the sealing lip of the valve seat and the valve core are conical surface sealing complexion. The valve core and the valve seat contact in conical surface and tightly connected with each other which can fulfill the proposal of eliminating fouling in high-viscosity, easy sedimentation and easy cocking medium, eliminating fouling inside the valve and preventing the event of being un-tightly closed of the valve due to the fouling. The utility model has the advantages of abrasion resisting, reducing local resistance loss and excellent sealing property.
Description
Technical field
The utility model belongs to a kind of shutoff valve of pipeline in the water drainage-supply system, and especially a kind of spool is taper, and latus rectum is at the stop valve of DN25-DN250.
Background technique
Now, the sealing surface of general stop valve is discoid valve, and spool is circular flat contact seal.Should not be used for during this structure is used viscosity greatly, the easy shortcoming of the medium of precipitation and coking.The long-term use, the sealing of stop valve is relatively poor.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, and a kind of awl core stop valve that can get rid of dirt and good seal is provided.
The purpose of this utility model realizes by following approach:
A kind of awl core stop valve, comprise valve seat, valve rod, spool, valve gap, valve seat is provided with water intake and water outlet, and perforation place of entery and delivery port is provided with a sealed mouth in the valve seat, spool is installed in the sealing mouth, it is characterized in that the sealed mouth of valve seat is that conical surface seal cooperates with spool.
Advantage of the present utility model:
The utility model spool contacts with the valve seat conical surface, fit closely, for viscosity greatly, the medium of easily precipitation and coking can realize pushing blowdown, eliminate dirty thing in the valve, prevent to cause valve to fit badly phenomenon because of the dirt influence.Have and resistance to wear, reduce characteristics such as local resistance loss, good airproof performance.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the utility model bipyramid face cone core stop valve schematic representation.
Fig. 3 is the utility model conical surface plane awl core stop valve schematic representation.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing:
As shown in Figure 1, a kind of awl core of the utility model stop valve, it comprises parts such as valve seat 4 (or claiming valve body), valve rod 2, spool 3, valve gap 1, valve seat 4 is provided with water intake 5 and water outlet 6, perforation place of entery and delivery port is provided with a sealed mouth in the valve seat 4, and spool 3 is installed in the sealing mouth, and the sealed mouth of valve seat 4 cooperates for conical surface seal with spool 3, its structure is that spool 3 is taper shape, and sealed mouth is the inner conical adaptive with its shape.Valve rod 2 one ends are fixedly connected on spool 3 tops, and the other end stretches out valve gap 1, and can drive spool 3 upper and lower motions.
Fig. 2 is the utility model bipyramid face cone core stop valve schematic representation, and the sealed mouth of valve seat 4 cooperates for the bipyramid face with spool 3.Be that spool 3 comprises tapered segment and following tapered segment, the tapering of last circular cone is greater than the tapering of following circular cone.The sealed mouth of valve seat 4 is and spool 3 corresponding two female cones that both form the bipyramid face and cooperate.The following conical surface is used to push blowdown, last conical surface contact seal.
Fig. 3 is the utility model conical surface plane awl core stop valve schematic representation, spool 3 top excircles are provided with a circle boss, and the lower surface of boss is the plane, and the top outer rim of the sealed mouth of valve seat 4 is a plane structure, the bottom is the inner conical structure, and both form the conical surface and add the plane cooperation.This structure is main contact seal with the plane, and conical surface extruding blowdown is auxilliary surface of contact.Valve seat 4 in this structure also can not cause the conical surface, keeps plane sealing.
Claims (3)
