Abstract
The utility model discloses a novel gas valve which comprises a valve body and a valve plug, wherein, the upper part of the valve body is connected with an air intake pipe; the front part of the valve body is connected with an air exhaust pipe; the back of the valve body is provided with a valve rod which extends into the inside of the valve body and is fixed with the valve plug. The valve plug is sphere shaped; the inside of the sphere shaped valve plug communicated with an air exhaust pipe and a communication hole of the air exhaust pipe. Seals are respectively arranged on the upper part of the sphere shaped valve plug, the sealing surface of the air intake pipe and the lower part of the sphere shaped valve; with the sphere shaped valve plug, the utility model improves the airtight performance of the gas valve, causes no gap in use, thereby preventing the gas leakage and ensuring safe usage.
Description
The utility model relates to a kind of coal gas gas valve.
Along with society and expanding economy, the combustion gas popularity rate improves day by day, so the gas safe problem is also more and more paid attention to by people.But coal gas gas valve of the prior art generally all adopts taper valve core, and as sealing surface, and conical surface seal is easy to generate the gap with the conical surface, uses a period of time can cause gas leakage later, and poisoning takes place.
The purpose of this utility model is: a kind of novel gas gas valve is provided, and this valve adopts spherical valve core, has improved the sealability of gas valve, uses and can not produce the gap, stops gas leakage, guarantees safe handling.
The technical solution of the utility model is: a kind of novel gas gas valve, comprise valve body, the valve body top is connected with suction tude, valve body the place ahead is connected with steam outlet pipe, the valve body rear be provided with stretch in the valve body and with the fixing valve rod of spool, described spool is spherical, is provided with the intercommunicating pore that is communicated with steam outlet pipe and steam outlet pipe in the spherical valve core, and the spherical valve core top intercommunicating pore and the sealing surface of suction tude and the below of spherical valve core are respectively equipped with sealing gasket.
The further technological scheme of the utility model is: a kind of novel gas gas valve, comprise valve body, the valve body top is connected with suction tude, valve body the place ahead is connected with steam outlet pipe, the valve body rear be provided with stretch in the valve body and with the fixing valve rod of spool, described spool is spherical, is provided with the intercommunicating pore that is communicated with steam outlet pipe and steam outlet pipe in the spherical valve core, and the spherical valve core top intercommunicating pore and the sealing surface of suction tude and the below of spherical valve core are respectively equipped with sealing gasket; Also be connected with ignitron on the described valve body, the intercommunicating pore in the spherical valve core is communicated with ignitron by valve rod.
The utility model has the advantages that:
1. the utility model changes the taper valve core of existing coal gas gas valve into spherical valve core, uses the back sealing surface can not produce the gap, can stop the gas leakage phenomenon, uses safer.
2. be arranged in the utility model spherical valve core sealing gasket up and down the body cavity chamber is divided into before and after two chambeies, and ante-chamber is communicated with steam outlet pipe, and spool and steam outlet pipe can be sealed better.
The utility model will be further described below in conjunction with drawings and Examples:
Fig. 1 is a structural representation of the present utility model;
Wherein: 1 valve body; 2 suction tude; 3 steam outlet pipes; 4 spools; 5 valve rods; 6 intercommunicating pores; 7 sealing gaskets; 8 ignitrons.
Embodiment: as shown in Figure 1, a kind of novel gas gas valve, comprise valve body [1], valve body [1] top is connected with suction tude [2], valve body [1] the place ahead is connected with steam outlet pipe [3], valve body [1] rear be provided with stretch in the valve body [1] and with the fixing valve rod [5] of spool [4], described spool [4] is spherical, be provided with the intercommunicating pore [6] that is communicated with suction tude [2] and steam outlet pipe [3] in the spherical valve core [4], spherical valve core [4] top intercommunicating pore [6] is respectively equipped with sealing gasket [7] with the sealing surface of suction tude [2] and the below of spherical valve core [4]; Also be connected with ignitron [8] on the described valve body [1], the intercommunicating pore [6] in the spherical valve core [4] is communicated with ignitron [8] by valve rod [5].
The utility model changes the taper valve core of existing coal gas gas valve into spherical valve core [4], uses the back sealing surface can not produce the gap, can stop the gas leakage phenomenon, uses safer; Be arranged in the utility model spherical valve core [4] sealing gasket [7] up and down valve body [1] inner cavity chamber is divided into before and after two chambeies, and ante-chamber is communicated with steam outlet pipe [3], and spool [1] and steam outlet pipe [3] can be sealed better.
Claims (2)
